[0169] Some embodiments of the methods and compositions provided herein relate to engineered immune cells and combinations thereof for immunotherapy. In several embodiments, engineered cells are engineered in various ways, for example, to express a receptor complex that induces cytotoxicity. As used herein, the term "cytotoxic receptor complex" should have its usual meaning, and (unless otherwise specified) also refers to chimeric antigen receptors (CARs) and chimeric receptors (also referred to as activating chimeric receptors for NKG2D chimeric receptors). In several embodiments, cells are further engineered to achieve changes in the responsiveness of cells to non-tumor tissues. Several embodiments relate to modifying T cells by various genetic engineering methods so that the alloreactivity of the resulting T cells is reduced and / or eliminated. Such T cells without alloreactivity can also be engineered to express chimeric antigen receptors (CARs), which allow T cells without alloreactivity to produce cytotoxic effects on tumor cells. In several embodiments, natural killer (NK) cells are also engineered to express receptor complexes (e.g., chimeric antigen receptors or chimeric receptors) that induce cytotoxicity. In several embodiments, combinations of these engineered immune cell types are used in immunotherapy to produce both rapid (NK cell-based) and durable (T cell-based) anti-tumor effects, with the advantage of little or no graft-versus-host disease (GvHD). Some embodiments include methods of using the compositions or cells in immunotherapy.
[0170] Although autologous CAR-T cell therapies have been developed and shown to have significant durability and efficacy in vivo, the majority of patients treated with autologous CAR T cell therapies experience cytokine release syndrome (CRS) and / or neurotoxicity. In addition, autologous CAR T cell therapies face numerous challenges, including the need to leukapheresis of patients and then prepare qualified CAR T cell products from patients who are often extremely ill, heavily pretreated, or both. It may be difficult or, in some cases, impossible to produce sufficient numbers of CAR T cells from such patients. In addition, potential patients may not survive the time required to produce the final CAR T cell product from their own T cells.
[0171] In contrast, NK cell therapy, including allogeneic NK cell therapy made from healthy donors, can avoid many of these challenges. For example, due to the better quality of the donor cells input, the manufacturing success rate of allogeneic CAR-NK cells may be higher. Allogeneic CAR-NK cell therapy can also be provided when the patient needs it, without having to wait for the preparation of the patient's own cells. Therefore, allogeneic NK cell therapy is being studied as a ready-made product. Although NK cells offer potential advantages, their persistence in the body is not as good as T cells. Therefore, it is necessary to find a solution to overcome this challenge. This article describes gene editing that can increase the persistence, efficacy (e.g., cytotoxicity) or both of NK cells. Embodiments of such gene-edited NK cells include compositions and methods of use for treating a disease or disorder (e.g., cancer) in a subject. For example, experiments described herein found that destroying specific genes (including, for example, ADAM17, MED12, CISH, CBLB, or a combination thereof) brought unexpected beneficial effects to NK cells, including enhanced cytotoxicity in vitro and in vivo. These results were observed in NK cells expressing CARs against different antigens (e.g., BCMA, CD19, or CD70). Without wishing to be bound by theory, these findings are consistent with the observation that such gene editing can provide advantages to NK cells expressing CARs, regardless of the specific antigen targeted by the CAR.
[0172] The term "anti-cancer effect" refers to a biological effect that can be manifested in various ways, including but not limited to a reduction in tumor size, a reduction in the number of cancer cells, a reduction in the number of metastases, an increase in life expectancy, a reduction in cancer cell proliferation, a reduction in cancer cell survival, and / or an improvement in various physiological symptoms associated with cancerous conditions. Cell type
[0173] Some embodiments of the methods and compositions provided herein relate to cells such as immune cells. In some embodiments, immune cells are engineered to express chimeric receptors that bind to antigens (e.g., antigens expressed by cancer cells). For example, immune cells (e.g., T cells) can be engineered to include chimeric receptors (e.g., chimeric receptors directed by CD19), or engineered to include nucleic acids encoding the chimeric receptors as described herein. In some embodiments, natural killer (NK) cells are engineered to express chimeric receptors that bind to antigens (e.g., antigens expressed by cancer cells). Additional embodiments relate to engineering a second group of cells so that they express another cytotoxic receptor complex, such as the NKG2D chimeric receptor complex disclosed herein. Therefore, in some embodiments, a combination or composition comprising two different types of immune cells (e.g., T cells and NK cells) is contemplated. In some embodiments, engineered T cells and engineered NK cells express the same chimeric receptor. In some embodiments, engineered T cells and engineered NK cells express different chimeric receptors. In some embodiments, engineered T cells and engineered NK cells express chimeric receptors that bind to the same antigen (e.g., different epitopes of the same antigen). In some embodiments, the engineered T cells and engineered NK cells express chimeric receptors that bind different antigens.
[0174] Additional embodiments relate to further genetic manipulation of NK cells (e.g., donor NK cells) to increase the persistence and / or efficacy of engineered NK cells. Still additional embodiments relate to further genetic manipulation of T cells (e.g., donor T cells) to reduce, disrupt, minimize, and / or eliminate the ability of donor T cells to produce allogeneic responses (graft-versus-host disease) to recipient cells. For example, in some embodiments, T cells are engineered to reduce allogeneic responses to recipient cells.
[0175] Traditional anti-cancer therapies rely on surgery, radiation therapy, chemotherapy, or a combination of these methods. As research has given people a deeper understanding of some of the pathogenesis of certain cancers, this knowledge has been used to develop targeted cancer therapies. Targeted therapy is a type of cancer treatment method that uses certain drugs that target specific genes or proteins in cancer cells or cells that support cancer growth (such as blood vessel cells) to reduce or prevent cancer cell growth. Recently, genetic engineering technology has made it possible to develop methods that utilize certain characteristics of the immune system to fight cancer. In some cases, the patient's own immune cells are modified to specifically eradicate the type of cancer that the patient suffers from. Various types of immune cells can be used, such as T cells, natural killer (NK) cells, or a combination thereof, as described in more detail below.
[0176] In order to promote cancer immunotherapy, provided herein are polynucleotides (e.g., encoding chimeric receptors), polypeptides (e.g., chimeric receptors), and vectors encoding chimeric antigen receptors (CARs), which comprise target binding moieties (e.g., extracellular binders of ligands, or chimeric receptors targeted by tumor markers expressed by cancer cells) and cytotoxic signaling complexes. For example, some embodiments include a polynucleotide, polypeptide, or vector encoding, for example, a chimeric antigen receptor for tumor markers (e.g., CD19, CD123, CD70, Her2, mesothelin, Claudin 6, BCMA, EGFR, etc.) to promote immune cell targeting of cancer and exert cytotoxic effects on cancer cells. Also provided herein are engineered immune cells (e.g., T cells or NK cells) expressing such CARs. In some embodiments, the chimeric antigen receptor binds to a ligand of NKG2D. In some embodiments, the chimeric antigen receptor binds to CD19. In some embodiments, the chimeric antigen receptor binds to CD70. In some embodiments, the chimeric antigen receptor binds to BCMA. In some embodiments, polynucleotides, polypeptides, and vectors are also provided herein, encoding a construct comprising an extracellular domain comprising two or more subdomains, for example, a first subdomain targeting CD19 comprising a CD19 binding portion disclosed herein, and a second subdomain comprising a C-type lectin-like receptor and a cytotoxic signaling complex. Also provided herein are engineered immune cells (e.g., T cells or NK cells) expressing such bispecific constructs. Also provided herein are methods for treating cancer and other uses of such cells in cancer immunotherapy.
[0177] Also provided herein are chimeric receptors comprising antigen binding domains and cytotoxic signaling complexes.For example, some embodiments include chimeric receptors for tumor antigens (such as CD19, BCMA or CD70).Also provided herein are genetically engineered immune cells (such as NK cells) expressing such CARs.In some embodiments, immune cells are subjected to gene editing (for example, at MED12 and / or CISH).
[0178] To promote cancer immunotherapy, polynucleotides (e.g., encoding chimeric receptors), polypeptides (e.g., chimeric receptors), and vectors encoding chimeric receptors are also provided herein, wherein the chimeric receptor comprises a target binding portion (e.g., an extracellular binder of a ligand expressed by a cancer cell) and a cytotoxic signaling complex. For example, some embodiments include a polynucleotide, polypeptide, or vector encoding, for example, an activating chimeric receptor comprising an extracellular domain of NKG2D, which targets tumor markers such as MICA, MICB, ULBP1, ULBP2, ULBP3, ULBP4, ULBP5, and ULBP6, to promote the targeting of immune cells to cancer and exert a cytotoxic effect on cancer cells. In some embodiments, the chimeric receptor comprises an extracellular domain of NKG2D.
[0179] Also provided herein are engineered immune cells (e.g., T cells or NK cells) expressing such chimeric receptors. In some embodiments, polynucleotides, polypeptides, and vectors are also provided herein, encoding a construct comprising an extracellular domain comprising two or more subdomains, e.g., a first and a second ligand binding receptor and a cytotoxic signaling complex. Also provided herein are engineered immune cells (e.g., T cells or NK cells, in some embodiments, the first and second ligand binding domains target the same ligand) expressing such bispecific constructs. Also provided herein are methods for treating cancer and other uses of such cells for cancer immunotherapy. Engineered cells for immunotherapy
[0180] In several embodiments, the cells of the immune system are engineered to have enhanced cytotoxic effects on target cells (such as tumor cells). For example, the cells of the immune system can be engineered to include chimeric receptors and / or tumor-oriented CARs as described herein. In several embodiments, leukocytes are used because their natural function is to protect the body from abnormal cell growth and infectious diseases. There are various types of leukocytes that play a specific role in the human immune system and are therefore preferred starting cells for the engineering of cells disclosed herein. Leukocytes include granulocytes and agranulocytes (referring to survival or lack of particles in the cytoplasm, respectively). Granulocytes include basophils, eosinophils, neutrophils and mast cells.

[0212] As mentioned above, a variety of cell types can be used for cellular immunotherapy. In addition, as described in more detail below and shown in the examples, these cells can be genetically modified to enhance one or more aspects of their efficacy (such as cytotoxicity) and / or persistence (such as active lifespan). As discussed herein, in several embodiments, NK cells are used for immunotherapy. In several embodiments provided herein, gene editing of NK cells can advantageously give the edited NK cells the ability to resist and / or overcome the various inhibitory signals produced in the tumor microenvironment.

[0213] As discussed below, in several embodiments, gene editing is employed to reduce or knock out expression of a target protein, for example by disrupting the underlying gene encoding the protein.

[0216] In several embodiments, gene editing is used to "knock in" or otherwise increase the transcription of a target gene. In several embodiments, the transcription of a target gene increases by about 30%, about 40%, about 50%, about 60%, about 70%, about 75%, about 80%, about 85%, about 90%, about 95%, about 97%, about 98%, about 99% or more (including any amount between the listed values).

[0218] Unless otherwise indicated to the contrary, guide RNA (gRNA) sequences expressed using deoxyribonucleotides refer to target DNA sequences (which are complementary to the corresponding non-target DNA sequences to which the gRNA binds) and should be considered to refer to those guide sequences used in actual applications (e.g., using ribonucleotides, wherein the ribonucleotide uracil replaces the deoxyribonucleotide thymine, whereas when thymine is used instead of uracil, both are complementary to adenine when expressing RNA or DNA sequences). In other words, the specific gRNA sequences provided herein are identical to the gRNA sequences used in actual applications, except that uracil is used instead of thymine in the gRNA sequence. For example, a gRNA with the sequence ATGCTCAATGCGTC (SEQ ID NO: 977) also refers to the following sequence AUGCUCAAUGCGUC (SEQ ID NO: 978); or a gRNA with the sequence AUGCUCAAUGCGUC (SEQ ID NO: 978) also refers to the following sequence ATGCTCAATGCGTC (SEQ ID NO: 977). In addition, the non-target DNA sequence bound by a specific gRNA sequence is complementary to the sequence of the specific gRNA. For example, a gRNA with the sequence ATGCTCAATGCGTC (SEQ ID NO: 977) binds to the non-target DNA sequence TACGAGTTACGCAG (SEQ ID NO: 979). In this case, the corresponding target DNA sequence complementary to the non-target DNA sequence is ATGCTCAATGCGTC (SEQ ID NO: 977).
[0219] In several embodiments, the gene editing of immune cells also provides unexpected enhanced amplification capacity, persistence and / or cytotoxicity of edited immune cells. As disclosed herein, engineered cells (such as those expressing CAR) can also be edited, and the two are combined to provide powerful cells for immunotherapy. In several embodiments, the editing makes the amplification, persistence and / or cytotoxicity of NK cells unexpectedly improved. In several embodiments, knocking out gene expression in NK cells removes the potent negative regulator or other inhibitory factors for NK cell signaling and / or activity, thereby relieving the inhibition of NK cells, and enhancing one or more aspects of NK cell homing, NK cell migration, NK cell activation, amplification, cytotoxicity and / or persistence. In addition, in several embodiments, the editing can enhance the function of NK cells and / or T cells in an originally inhibitory tumor microenvironment.
[0220] In several embodiments, the gene editing of any target gene disclosed herein (whether knocking out or knocking in) is achieved by targeting the introduction of DNA breaks, which are subsequently achieved by means of DNA repair mechanisms. In several embodiments, the double-strand break of DNA is repaired by non-homologous end joining (NHEJ), wherein an enzyme is used to directly connect the DNA end to the other end to repair the break. NHEJ is an error-prone process. Typically, in the absence of a repair template, the NHEJ process reconnects the broken DNA chain ends, which often results in nucleotide deletions and insertions at the cut site. However, in several embodiments, double-strand breaks (DSBs) are repaired by homology-directed repair (HDR), which has the advantage of being more accurate, thereby achieving sequence-specific breakage and repair. HDR uses homologous sequences as templates for regenerating missing DNA sequences at breakpoints, such as within sequences homologous to the flanking sequences of the double-strand break, with a vector of desired genetic elements (e.g., insertion elements for destroying gene coding sequences). This will result in the desired change (e.g., insertion) being inserted at the site of the DSB. The HDR approach can occur by classical HDR approaches or alternative HDR approaches. Unless otherwise indicated, the terms "HDR" or "homologous directed repair" as used herein encompass both classical HDR and alternative HDR.
[0221] Classical HDR, "canonical homology-directed repair" or "cHDR" are used interchangeably and refer to the process of repairing DNA damage using homologous nucleic acids (e.g., endogenous homologous sequences, such as sister chromatids; or exogenous nucleic acids, such as donor templates). Classical HDR typically works when significant resection occurs at the DSB, forming at least one segment of single-stranded DNA. In normal cells, classical homology-directed repair typically involves a series of steps, such as break recognition, break stabilization, resection, stabilization of single-stranded DNA, formation of DNA crossover intermediates, splitting and ligation of crossover intermediates. The classical HDR process requires RAD51 and BRCA2, and the homologous nucleic acid (e.g., repair template) is typically double-stranded. In classical HDR, a double-stranded polynucleotide (e.g., a double-stranded repair template) is introduced, which contains a sequence homologous to the target sequence, and this sequence will be directly integrated into the target sequence, or used as a template to insert the sequence or portion of the repair template into the target gene. After resection of the break, repair can proceed through different pathways, such as through the double Holliday junction model (also known as double-strand break repair, or DSBR pathway), or through the synthesis-dependent strand annealing (SDSA) pathway.
[0222] In the double Holliday ligation model, the overhangs of the two single strands of the target sequence invade the homologous sequence in the double-stranded polynucleotide (such as the double-stranded donor template), resulting in strand invasion, which leads to an intermediate with two Holliday junctions. As new DNA is synthesized from the ends of the invading strands to fill the gap created by the excision, the junction migrates. The ends of the newly synthesized DNA are connected to the ends of the excision, and the junction splits, resulting in an insertion at the target sequence or a portion of the target sequence containing the gene variant. When the junction splits, it can cross with a polynucleotide (such as a repair template).
[0223] In the SDSA approach, only one single-stranded overhang invades a polynucleotide (such as a donor template), and new DNA is synthesized from the end of the invading strand to fill the gap created by the excision. The newly synthesized DNA then anneals to the remaining single-stranded overhang, new DNA is synthesized to fill the gap, and the strands are ligated to produce a modified DNA duplex.
[0224] Alternative HDR, "alternative homology-directed repair" or "alternative HDR" are used interchangeably and, in some embodiments, refer to the process of repairing DNA damage using homologous nucleic acids (e.g., endogenous homologous sequences, such as sister chromatids; or exogenous nucleic acids, such as repair templates). Alternative HDR differs from classical HDR in that the process uses a different pathway from classical HDR and can be inhibited by the classical HDR mediators RAD51 and BRCA2. In addition, alternative HDR is also characterized by involving single-stranded or nicked homologous nucleic acid templates (such as repair templates), while classical HDR often involves double-stranded homologous templates. In the alternative HDR approach, a single-stranded template polynucleotide (such as a repair template) is introduced. The nick, single-strand break or double-strand break at the cleavage site is used to change the desired target site (such as a gene variant in a target gene), which is mediated by a nuclease molecule, and resection occurs at the break to expose a single-stranded overhang. As described herein, the sequence of a template polynucleotide (such as a repair template) is typically integrated into DNA via the SDSA approach to change the target site. In some embodiments, HDR is performed by introducing one or more agents capable of inducing DSBs and a repair template (such as a single-stranded oligonucleotide) into a cell. The introduction operation can be performed by any suitable delivery method. The conditions that allow HDR to occur can be any conditions suitable for performing homology-directed repair (HDR) in a cell.
[0225] In several embodiments, gene editing is accomplished by one or more engineered nucleases. In several embodiments, restriction endonucleases are used, particularly when double-strand breaks need to be generated in multiple regions. In several embodiments, bioengineered nucleases are used. According to various embodiments, one or more of zinc finger nucleases (ZFNs), transcription activator-like effector nucleases (TALENs), meganucleases, and / or clustered regularly interspaced short palindromic repeats (CRISPR / Cas9) systems are used to specifically edit genes encoding one or more TCR subunits.
[0226] The characteristic of a meganuclease is that it can recognize and cut long DNA sequences (14 to 40 base pairs). In several embodiments, a meganuclease from the LAGLIDADG family is used, and mutagenesis and screening are performed to generate a meganuclease variant capable of recognizing unique sequences (such as specific sites in TCR subunits (such as TRAC), CISH or any other target gene disclosed herein). The target site in the TCR subunit can be easily identified. More information about target sites in the region of TCR can be found in U.S. Patent Publication No. 2018 / 0325955 and U.S. Patent Publication No. 2015 / 0017136, the contents of which are incorporated herein by reference in their entirety. In several embodiments, two or more meganucleases or their functional fragments are fused to create a hybrid enzyme that recognizes the target sequence required in a target gene (such as CISH).
[0227] Unlike large-scale nucleases, zinc finger nucleases (ZFNs) and transcription activator-like effector nucleases (TALENs) work based on non-specific DNA cutting catalytic domains, which are connected to specific DNA sequence recognition peptides such as zinc fingers or transcription activator-like effectors (TALEs). Advantageously, zinc finger nucleases and transcription activator-like effector nucleases can therefore achieve sequence-independent DNA cutting while having high sequence specificity in target recognition. Zinc finger motifs naturally play a role in transcription factors, identifying specific DNA sequences for transcription. The C-terminal portion of each zinc finger is responsible for the specific recognition of the DNA sequence. Although the sequence recognized by zinc finger nucleases is relatively short (such as about 3 base pairs), in several embodiments, 2, 3, 4, 5, 6, 7, 8, 9, 10 or more zinc finger combinations whose recognition sites have been characterized are used to target specific sequences, such as part of the TCR (or immune checkpoint). The combined zinc finger nuclease is then fused to the catalytic domain of an endonuclease (such as FokI, optionally a FokI heterodimer) to induce targeted DNA breakage. More information about using zinc finger nucleases to edit TCR subunits and / or immune checkpoints can be found in U.S. Patent No. 9,597,357, the contents of which are incorporated herein by reference.
[0228] Transcription activator-like effector nucleases (TALENs) are specific DNA binding proteins characterized by having a series of 33 or 34 amino acid repeats. Like zinc finger nucleases, TALENs are fusions of the DNA cleavage domain of a nuclease with a TALE domain, which enables the introduction of sequence-independent double-stranded DNA breaks while enabling highly accurate recognition of target sites. TALENs can create double-strand breaks at the target site, which can be repaired by error-prone non-homologous end joining (NHEJ), which results in gene disruption by introducing small insertions or deletions. Advantageously, TALENs are used in several embodiments, at least in part because they have higher specificity in DNA binding, reduced off-target effects, and easier construction of DNA binding domains.
[0229] CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats) is a genetic element that bacteria use to resist viruses. The repetitive sequence is a short sequence derived from the viral genome and integrated into the bacterial genome. Cas (CRISPR-associated protein) processes these sequences and cuts matching viral DNA sequences. By introducing a plasmid containing the Cas gene and a specifically constructed CRISPR into eukaryotic cells, the eukaryotic genome can be cut at any desired position. More information about CRISPR can be found in U.S. Patent Publication No. 2014 / 0068797, the contents of which are incorporated herein by reference. In several embodiments, CRISPR is used to manipulate genes encoding target genes to be knocked out or knocked in (such as CISH, TGFBR2, TCR, B2M, CIITA, CD47, HLA-E, etc.). In several embodiments, CRISPR is used to edit one or more TCRs of T cells and / or genes encoding one or more immune checkpoints. In several embodiments, immune checkpoints are selected from one or more of CTLA4 and PD1. In several embodiments, CRISPR is used to truncate one or more of TCRα, TCRβ, TCRγ, and TCRδ. In several embodiments, the TCR is truncated without affecting the function of the CD3ζ signaling domain of the TCR.
[0230] Depending on the embodiment and the target gene to be edited, Class 1 or Class 2 Cas proteins are used. In several embodiments, Class 1 Cas proteins are used, and the Cas protein types are selected from the following types: I, IA, IB, IC, ID, IE, IF, IU, III, IIIA, IIIB, IIIC, IIID, IV, IVA, IVB, and combinations thereof. In several embodiments, the Cas protein is selected from Cas3, Cas8a, Cas5, Cas8b, Cas8c, Cas10d, Cse1, Cse2, Csy1, Csy2, Csy3, GSU0054, Cas10, Csm2, Cmr5, Cas10, Csx11, Csx10, Csf1, and combinations thereof. In several embodiments, Class 2 Cas proteins are used, and the Cas protein types are selected from the following types: II, IIA, IIB, IIC, V, VI, and combinations thereof. In several embodiments, the Cas protein is selected from Cas9, Csn2, Cas4, Cas12a (formerly known as Cpf1), C2c1, C2c3, Cas13a (formerly known as C2c2), Cas13b, Cas13c, CasX, CasY, and combinations thereof. In some embodiments, the Cas protein is Cas9. In some embodiments, two types of CasX are used, wherein CasX is capable of forming a complex with a guide nucleic acid, and wherein the complex can bind to a target DNA, and wherein the target DNA comprises a non-target strand and a target strand. In some embodiments, two types of CasY are used, wherein CasY is capable of binding to and modifying a target nucleic acid and / or a polypeptide associated with a target nucleic acid. Targets for gene editing
[0231] As described above, gene editing can be used to destroy one or more target genes to enhance the function (such as amplification ability, cytotoxicity) or persistence (lifespan or anti-hypoxia ability) of immune cells (such as NK cells). In some embodiments, ADAM17, HIF-1α, DGKζ, GSK-3β, LAG3, TIM3, TRIM29, IL-1R8, CD38, FBP-1, INSIG1, MED12, MED13, CCNC, CDK8, ID3, SOX4, or any combination thereof are used to edit immune cells. In some embodiments, ADAM17, HIF-1α, DGKζ, GSK-3β, LAG3, TIM3, TRIM29, IL-1R8, CD38, FBP-1, INSIG1, MED12, MED13, CCNC, CDK8, CBLB, CISH, ID3, SOX4, or any combination thereof are used to edit immune cells.
[0232] As a non-limiting example, in several embodiments, a member of the disintegrin metalloproteinase domain (ADAM) family (specifically ADAM17) is a target for gene editing. ADAM17 (located on chromosome 2) is associated with antibody-dependent cell-mediated cytotoxicity (ADCC), a key mechanism of action in anti-tumor responses. CD16A is a membrane-bound protein expressed by NK cells and a receptor for the Fc portion of IgG. Although engagement of CD16A (e.g., by antibody-coated target cells) triggers NK cell-mediated ADCC, upon NK cell activation, CD16A is cleaved from the NK cell surface and rapidly downregulated (either in vivo or in vitro, e.g., by PMA). ADAM17 is considered to be the main protease responsible for cleaving CD16A from the surface of NK cells; inhibition of ADAM17 (e.g., by disrupting ADAM17 expression) reduces, improves, or otherwise inhibits the cleavage of CD16A, thereby allowing ADCC to continue as an effective anti-tumor pathway (Wu et al., J Leukoc Biol (2019) 105(6):1297-1303). In addition, CD62 ligand (CD62L) is a substrate of ADAM17, and in several embodiments, disrupting the expression function of ADAM17 can stabilize the expression of CD62L. CD62L (L-selectin molecule) mediates homing of leukocytes to lymphoid organs. CD56dimCD62L+ cells represent a unique subset of mature, multifunctional NK cells that influence the intensity of local NK cell responses, particularly through the ability to produce IFN-γ after cytokine stimulation, the ability to proliferate in vivo during viral infection, and the ability to kill target cells after activating receptor engagement. Therefore, in several embodiments, stabilizing CD62L can further enhance the function of NK cells.
[0233] In several embodiments, gene editing reduces the transcription of ADAM17 by about 30%, about 40%, about 50%, about 60%, about 70%, about 75%, about 80%, about 85%, about 90%, about 95%, about 97%, about 98%, about 99% or more (including any amount between the listed values). In several embodiments, gene editing reduces the transcription of ADAM17 by at least about 30%, in several embodiments, gene editing reduces the transcription of ADAM17 by at least about 40%, in several embodiments, gene editing reduces the transcription of ADAM17 by at least about 50%, in several embodiments, gene editing reduces the transcription of ADAM17 by at least about 60%, in several embodiments, gene editing reduces the transcription of ADAM17 by at least about 70%, in several embodiments, gene editing reduces the transcription of ADAM17 by at least about 80%, and in several embodiments, gene editing reduces the transcription of ADAM17 by at least about 90%.
[0234] In several embodiments, gene editing can reduce the expression of the target protein by about 30%, about 40%, about 50%, about 60%, about 70%, about 75%, about 80%, about 85%, about 90%, about 95%, about 97%, about 98%, about 99% or more (including any amount between the listed values). In several embodiments, gene editing reduces the expression of ADAM17 by about 30%, about 40%, about 50%, about 60%, about 70%, about 75%, about 80%, about 85%, about 90%, about 95%, about 97%, about 98%, about 99% or more (including any amount between the listed values).

[0235] In several embodiments, a guide RNA (gRNA) comprising any one of SEQ ID NOs: 682-687 is used to disrupt (eg, reduce expression of) the ADAM17 gene.
[0236] In several embodiments, hypoxia-inducible factor 1α (HIF1α) is a target for gene editing. HIF1α (which is located on chromosome 15) is a transcriptional activator of CD274 (also known as PDL1). When hypoxic conditions exist, HIF1α interacts with the hypoxia response element in the promoter of PDL1, thereby promoting increased expression of PDL1. PDL1 expression is upregulated on a variety of cells, including tumor cells, immune cells (including MDSCs, macrophages, DCs, and bone marrow-derived macrophages (BMDMs)), and other cells in the tumor microenvironment (TME). Through the binding of PD1 to PDL1, it is used to inhibit the ability of T cells and / or NK cells to kill tumors. Studies using single-cell RNA sequencing of tumor-infiltrating NK cells have shown that inhibition of HIF1α promotes the activity of tumor-infiltrating NK cells (Ni et al., Immunity (2020) 52(6):1075-87). In some embodiments, loss of HIF1α in NK cells inhibits tumor growth by, for example, stimulating ineffective angiogenesis (eg, starving tumor cells of a blood supply).
[0237] In several embodiments, gene editing reduces the transcription of HIF1α by about 30%, about 40%, about 50%, about 60%, about 70%, about 75%, about 80%, about 85%, about 90%, about 95%, about 97%, about 98%, about 99% or more (including any amount between the listed values). In several embodiments, gene editing reduces the transcription of HIF1α by at least about 30%, in several embodiments, gene editing reduces the transcription of HIF1α by at least about 40%, in several embodiments, gene editing reduces the transcription of HIF1α by at least about 50%, in several embodiments, gene editing reduces the transcription of HIF1α by at least about 60%, in several embodiments, gene editing reduces the transcription of HIF1α by at least about 70%, in several embodiments, gene editing reduces the transcription of HIF1α by at least about 80%, and in several embodiments, gene editing reduces the transcription of HIF1α by at least about 90%.
[0238] In several embodiments, gene editing can reduce the expression of the target protein by about 30%, about 40%, about 50%, about 60%, about 70%, about 75%, about 80%, about 85%, about 90%, about 95%, about 97%, about 98%, about 99% or more (including any amount between the listed values). In several embodiments, gene editing reduces the expression of HIF1α by about 30%, about 40%, about 50%, about 60%, about 70%, about 75%, about 80%, about 85%, about 90%, about 95%, about 97%, about 98%, about 99% or more (including any amount between the listed values).

[0239] In several embodiments, a guide RNA (gRNA) comprising any one of SEQ ID NOs: 750-760 is used to disrupt (eg, reduce expression of) the HIF1α gene.
[0240] As a non-limiting example, diacylglycerol kinase ζ (DGKζ) is a target for gene editing to reduce or knock out expression. DGKζ is located on chromosome 11 and is a negative regulator of diacylglycerol kinase-mediated signaling. Studies have shown that mice lacking DGKζ increase cytokine production and degranulation, which in some cases occurs in an ERK (also known as Ras-Raf-MEK-ERK pathway)-dependent manner. In addition, CRISPR / Cas9-mediated DGK knockout can improve T cell function (such as anti-tumor activity). However, in NK cells, destroying DGKζ is considered to be particularly beneficial because, according to some embodiments, destroying DGKζ does not negatively affect the expression or function of inhibitory NK cell receptors, thereby maintaining the natural balance of NK cell activation and inhibitory signals that regulate NK cell activity in many aspects (SingH and Kambayashi, Front Cell Dev Bio (2016) 4: 96). Thus, in several embodiments, enhancement of NK cell function is achieved by enhancing NK cell activity and signaling by disinhibiting the negative regulatory aspects of activation pathways rather than by disrupting the "brakes" on NK cell function (expression or function of inhibitory NK cell receptors, which can lead to uncontrolled NK cell activity and potential off-target cytotoxicity).
[0241] In several embodiments, gene editing reduces the transcription of DGKζ by about 30%, about 40%, about 50%, about 60%, about 70%, about 75%, about 80%, about 85%, about 90%, about 95%, about 97%, about 98%, about 99% or more (including any amount between the recited values). In several embodiments, gene editing reduces the transcription of DGKζ by at least about 30%, in several embodiments, gene editing reduces the transcription of DGKζ by at least about 40%, in several embodiments, gene editing reduces the transcription of DGKζ by at least about 50%, in several embodiments, gene editing reduces the transcription of DGKζ by at least about 60%, in several embodiments, gene editing reduces the transcription of DGKζ by at least about 70%, in several embodiments, gene editing reduces the transcription of DGKζ by at least about 80%, and in several embodiments, gene editing reduces the transcription of DGKζ by at least about 90%.
[0242] In several embodiments, gene editing can reduce the expression of the target protein by about 30%, about 40%, about 50%, about 60%, about 70%, about 75%, about 80%, about 85%, about 90%, about 95%, about 97%, about 98%, about 99% or more (including any amount between the listed values). In several embodiments, gene editing reduces the expression of DGKζ by about 30%, about 40%, about 50%, about 60%, about 70%, about 75%, about 80%, about 85%, about 90%, about 95%, about 97%, about 98%, about 99% or more (including any amount between the listed values). In several embodiments, gene editing reduces the expression of DGKζ by at least about 30%, in several embodiments, gene editing reduces the expression of DGKζ by at least about 40%, in several embodiments, gene editing reduces the expression of DGKζ by at least about 50%, in several embodiments, gene editing reduces the expression of DGKζ by at least about 60%, in several embodiments, gene editing reduces the expression of DGKζ by at least about 70%, in several embodiments, gene editing reduces the expression of DGKζ by at least about 80%, and in several embodiments, gene editing reduces the expression of DGKZ by at least about 90%.
[0243] In several embodiments, a guide RNA (gRNA) comprising any one of SEQ ID NOs: 688-723 is used to disrupt (e.g., reduce expression of) the DGKze gene.
[0244] In several embodiments, glycogen synthase kinase-3β (GSK3β) is a target for gene editing. GSK3β is located on chromosome 11 and is a ubiquitously expressed serine / threonine kinase that is involved in a variety of cellular functions, including differentiation, survival, glycogen metabolism, protein synthesis, immune response, and cell death. In patients with AML, inhibition of GSK3β is thought to restore the cytotoxicity of NK cells. In addition, GSK3β inhibition (e.g., by small molecule inhibitors) can drive NK cell maturation and, in some embodiments, enhance anti-tumor activity (Cichocki et al., Cancer Res (2017) 77(20): 5664-75). Normal levels of GSK3β are thought to have a negative regulatory effect on multiple aspects of NK cell function, including those functions triggered by one or more (e.g., combinations) of activating NK cell receptors. Returning to the role of small molecules, small molecule inhibitors of GSK3β can specifically inhibit the transcription of the inhibitory co-receptor LAG-3 (Rudd et al., Cell Rep (2020) 30(7):2075-82; discussed in more detail below).
[0245] In several embodiments, gene editing reduces the transcription of GSK3β by about 30%, about 40%, about 50%, about 60%, about 70%, about 75%, about 80%, about 85%, about 90%, about 95%, about 97%, about 98%, about 99% or more (including any amount between the listed values). In several embodiments, gene editing reduces the transcription of GSK3β by at least about 30%, in several embodiments, gene editing reduces the transcription of GSK3β by at least about 40%, in several embodiments, gene editing reduces the transcription of GSK3β by at least about 50%, in several embodiments, gene editing reduces the transcription of GSK3β by at least about 60%, in several embodiments, gene editing reduces the transcription of GSK3β by at least about 70%, in several embodiments, gene editing reduces the transcription of GSK3β by at least about 80%, and in several embodiments, gene editing reduces the transcription of GSK3β by at least about 90%.
[0246] In several embodiments, gene editing can reduce the expression of the target protein by about 30%, about 40%, about 50%, about 60%, about 70%, about 75%, about 80%, about 85%, about 90%, about 95%, about 97%, about 98%, about 99% or more (including any amount between the listed values). In several embodiments, gene editing reduces the expression of GSK3β by about 30%, about 40%, about 50%, about 60%, about 70%, about 75%, about 80%, about 85%, about 90%, about 95%, about 97%, about 98%, about 99% or more (including any amount between the listed values). In several embodiments, gene editing reduces the expression of GSK3β by at least about 30%, in several embodiments, gene editing reduces the expression of GSK3β by at least about 40%, in several embodiments, gene editing reduces the expression of GSK3β by at least about 50%, in several embodiments, gene editing reduces the expression of GSK3β by at least about 60%, in several embodiments, gene editing reduces the expression of GSK3β by at least about 70%, in several embodiments, gene editing reduces the expression of GSK3β by at least about 80%, and in several embodiments, gene editing reduces the expression of GSK3β by at least about 90%.
[0247] In several embodiments, a guide RNA (gRNA) comprising any one of SEQ ID NOs: 724-749 is used to disrupt (eg, reduce expression of) the GSK3β gene.
[0248] In several embodiments, lymphocyte activation gene 3 (LAG3) is a target for gene editing. LAG3 (located on chromosome 12) acts as an immune checkpoint and inhibits the activation of its host cells (such as NK cells and / or T cells), and generally promotes a more suppressive immune response. For example, on T cells, LAG3 reduces cytokine and granzyme production and cell proliferation, while promoting T cell differentiation into regulatory T cells rather than cytotoxic T cells. LAG3 acts as a checkpoint in NK cells, reducing cytokine production by CD56+Dim cytotoxic cells.
[0249] In several embodiments, gene editing reduces LAG3 transcription by about 30%, about 40%, about 50%, about 60%, about 70%, about 75%, about 80%, about 85%, about 90%, about 95%, about 97%, about 98%, about 99%, or more (including any amount in between). In several embodiments, gene editing reduces LAG3 transcription by at least about 30%; in several embodiments, gene editing reduces LAG3 transcription by at least about 40%; in several embodiments, gene editing reduces LAG3 transcription by at least about 50%; in several embodiments, gene editing reduces LAG3 transcription by at least about 60%; in several embodiments, gene editing reduces LAG3 transcription by at least about 70%; in several embodiments, gene editing reduces LAG3 transcription by at least about 80%; in several embodiments, gene editing reduces LAG3 transcription by at least about 90%.
[0250] In several embodiments, gene editing can reduce the expression of the target protein by about 30%, about 40%, about 50%, about 60%, about 70%, about 75%, about 80%, about 85%, about 90%, about 95%, about 97%, about 98%, about 99% or more (including any amount between the listed values). In several embodiments, gene editing reduces the expression of LAG3 by about 30%, about 40%, about 50%, about 60%, about 70%, about 75%, about 80%, about 85%, about 90%, about 95%, about 97%, about 98%, about 99% or more (including any amount between the listed values). In several embodiments, gene editing reduces the expression of LAG3 by at least about 30%; in several embodiments, gene editing reduces the expression of LAG3 by at least about 40%; in several embodiments, gene editing reduces the expression of LAG3 by at least about 50%; in several embodiments, gene editing reduces the expression of LAG3 by at least about 60%; in several embodiments, gene editing reduces the expression of LAG3 by at least about 70%; in several embodiments, gene editing reduces the expression of LAG3 by at least about 80%; and in several embodiments, gene editing reduces the expression of LAG3 by at least about 90%.
[0251] In several embodiments, a guide RNA (gRNA) comprising any one of SEQ ID NOs: 761-789 is used to disrupt (e.g., reduce expression of) the LAG3 gene.
[0252] In several embodiments, T-cell immunoglobulin and mucin domain 3 (TIM3) is a target for gene editing. TIM3 is a receptor expressed on NK cells and is considered a marker of dysfunctional NK cells. TIM3 is an immune checkpoint and belongs to the TIM protein family. TIM3 has multiple ligands, including CEACAM1, high-mobility group protein B1 (HMGB1), phosphatidylserine (PtdSer), and galectin-9 (Gal-9), which interact with TIM3 to reduce cell signaling. Like LAG3 mentioned above, TIM3 is induced by hypoxia, for example in certain regions of the tumor microenvironment (along with other genes, including CTLA4, PD1, PDL1, CD47, and other immune checkpoints). In several embodiments, genetic disruption of TIM3 reduces the negative effects of a hypoxic tumor microenvironment and can enhance NK cell anti-tumor activity.
[0253] In several embodiments, gene editing reduces the transcription of TIM3 by about 30%, about 40%, about 50%, about 60%, about 70%, about 75%, about 80%, about 85%, about 90%, about 95%, about 97%, about 98%, about 99% or more (including any amount between the listed values). In several embodiments, gene editing reduces the transcription of TIM3 by at least about 30%; in several embodiments, gene editing reduces the transcription of TIM3 by at least about 40%; in several embodiments, gene editing reduces the transcription of TIM3 by at least about 50%; in several embodiments, gene editing reduces the transcription of TIM3 by at least about 60%; in several embodiments, gene editing reduces the transcription of TIM3 by at least about 70%; in several embodiments, gene editing reduces the transcription of TIM3 by at least about 80%; in several embodiments, gene editing reduces the transcription of TIM3 by at least about 90%.
[0254] In several embodiments, gene editing can reduce the expression of the target protein by about 30%, about 40%, about 50%, about 60%, about 70%, about 75%, about 80%, about 85%, about 90%, about 95%, about 97%, about 98%, about 99% or more (including any amount between the listed values). In several embodiments, gene editing reduces the expression of TIM3 by about 30%, about 40%, about 50%, about 60%, about 70%, about 75%, about 80%, about 85%, about 90%, about 95%, about 97%, about 98%, about 99% or more (including any amount between the listed values). In several embodiments, gene editing reduces the expression of TIM3 by at least about 30%; in several embodiments, gene editing reduces the expression of TIM3 by at least about 40%; in several embodiments, gene editing reduces the expression of TIM3 by at least about 50%; in several embodiments, gene editing reduces the expression of TIM3 by at least about 60%; in several embodiments, gene editing reduces the expression of TIM3 by at least about 70%; in several embodiments, gene editing reduces the expression of TIM3 by at least about 80%; and in several embodiments, gene editing reduces the expression of TIM3 by at least about 90%.
[0255] In several embodiments, a guide RNA (gRNA) comprising any one of SEQ ID NOs: 790-825 is used to disrupt (eg, reduce expression of) the TIM3 gene.
[0256] In several embodiments, tripartite motif-containing protein 29 (TRIM29) is a target of gene editing. TRIM29 (located on chromosome 11) is a member of a protein family involved in many biological processes, including cell development, differentiation, apoptosis, and tumorigenesis. TRIM29 is induced by IL-12 and IL-18 in NK cells, and because it has E3 ubiquitin ligase function, it promotes the proteasome-mediated degradation of various target genes (such as TAB2 (TGF-β activated kinase binding protein 2)), which leads to the inhibition of IFN-γ production of activated NK cells, thereby limiting their cytotoxicity (Dou et al., J Immunol (2019) 203 (4): 873-80). In several embodiments, for example, by gene editing, the deletion of TRIM29 in NK cells can lead to significantly enhanced NK cell function even after IL-12 and IL-18 stimulation.
[0257] In several embodiments, gene editing reduces the transcription of TRIM29 by about 30%, about 40%, about 50%, about 60%, about 70%, about 75%, about 80%, about 85%, about 90%, about 95%, about 97%, about 98%, about 99% or more (including any amount between the listed values). In several embodiments, gene editing reduces the transcription of TRIM29 by at least about 30%; in several embodiments, gene editing reduces the transcription of TRIM29 by at least about 40%; in several embodiments, gene editing reduces the transcription of TRIM29 by at least about 50%; in several embodiments, gene editing reduces the transcription of TRIM29 by at least about 60%; in several embodiments, gene editing reduces the transcription of TRIM29 by at least about 70%; in several embodiments, gene editing reduces the transcription of TRIM29 by at least about 80%; in several embodiments, gene editing reduces the transcription of TRIM29 by at least about 90%.
[0258] In several embodiments, gene editing can reduce the expression of the target protein by about 30%, about 40%, about 50%, about 60%, about 70%, about 75%, about 80%, about 85%, about 90%, about 95%, about 97%, about 98%, about 99% or more (including any amount between the listed values). In several embodiments, gene editing reduces the expression of TRIM29 by about 30%, about 40%, about 50%, about 60%, about 70%, about 75%, about 80%, about 85%, about 90%, about 95%, about 97%, about 98%, about 99% or more (including any amount between the listed values). In several embodiments, gene editing reduces the expression of TRIM29 by at least about 30%; in several embodiments, gene editing reduces the expression of TRIM29 by at least about 40%; in several embodiments, gene editing reduces the expression of TRIM29 by at least about 50%; in several embodiments, gene editing reduces the expression of TRIM29 by at least about 60%; in several embodiments, gene editing reduces the expression of TRIM29 by at least about 70%; in several embodiments, gene editing reduces the expression of TRIM29 by at least about 80%; and in several embodiments, gene editing reduces the expression of TRIM29 by at least about 90%.
[0259] In several embodiments, a guide RNA (gRNA) comprising any one of SEQ ID NOs: 826-835 is used to disrupt (eg, reduce expression of) the TRIM29 gene.
[0260] In several embodiments, interleukin-1 receptor 8 (IL-1R8) is a target for gene editing. IL-1R8 (located on chromosome 11) is a member of the interleukin-1 receptor (ILR) family and acts as a negative regulator of signaling pathways downstream of ILRs and Toll-like receptors (TLRs), as well as inflammation. IL-1R8 is a co-receptor for IL-37 with IL-1R5 / IL-18Rα. IL-1R8 is a checkpoint in NK cells that negatively regulates anti-tumor and antiviral activity.

[0264] In several embodiments, CD38 is a target for gene editing. CD38 (located on chromosome 4) is an extracellular enzyme with nicotinamide adenine dinucleotide-positive (NAD+) glycohydrolase and ADP-ribosyl cyclase activities. CD38 is also expressed on a variety of tumor cells, such as multiple myeloma cells and acute myeloid leukemia cells. The function of CD38 and these glycohydrolase and cyclase activities produce the immunosuppressive molecule adenosine in certain cases, which: (i) inhibits the lysis of tumor cells by T cells and NK cells; (ii) induces the production of M2 macrophages and tolerogenic dendritic cells (DC); and / or (iii) induces Treg expansion. In addition, the endogenous expression of CD38 can cause problems for the persistence of therapeutic cells, for example, if a CAR targeting CD38 is used, it can lead to fratricide.
[0265] In several embodiments, gene editing reduces CD38 transcription by about 30%, about 40%, about 50%, about 60%, about 70%, about 75%, about 80%, about 85%, about 90%, about 95%, about 97%, about 98%, about 99%, or more (including any amount in between).

[0268] In several embodiments, fructose-1,6-bisphosphatase (FBP1) is a target for gene editing. FBP1 (located on chromosome 9) is a rate-limiting enzyme involved in gluconeogenesis. It primarily promotes gluconeogenesis while inhibiting glycolysis. FBP1-related impairment of NK cell glycolysis leads to NK cell dysfunction (Cong et al., Cell Metab (2018) 28(2):243-55). However, according to several embodiments, disrupting FBP1 expression restores NK cell function.
[0269] In several embodiments, gene editing reduces the transcription of FBP1 by about 30%, about 40%, about 50%, about 60%, about 70%, about 75%, about 80%, about 85%, about 90%, about 95%, about 97%, about 98%, about 99% or more (including any amount in between).

[0272] In some embodiments, insulin-induced gene 1 (INSIG1) is a target for gene editing. INSIG1 (located on chromosome 7) is a negative regulator of sterol regulatory element binding protein (SRBP) transcription. SRBP (after transcription and expression) is a protein involved in key aspects of glucose metabolism in NK cells, particularly related to NK cell functional responses (such as cytotoxicity) (Assmann et al., Nat Immunol (2017) 18(11): 1197-1206). According to some embodiments, disruption of INSIG1 expression relieves inhibition, thereby restoring NK cell function.
[0273] In several embodiments, gene editing reduces transcription of INSIG1 by about 30%, about 40%, about 50%, about 60%, about 70%, about 75%, about 80%, about 85%, about 90%, about 95%, about 97%, about 98%, about 99%, or more (including any amount in between).

[0276] Cells require a variety of different types of molecular complexes to carry out the cellular processes of transcription and translation. These complexes, composed of multiple (sometimes different) subunits, can confer specific functions on cells, depending on their assembly and activity. One such molecular complex is the Mediator complex, which is expressed and essential in cells where genes are actively expressed (e.g., immune cells like NK cells). It primarily acts as a "molecular bridge," connecting two otherwise unconnected regions of DNA within the cell. For example, it can connect promoters and enhancers, thereby physically positioning the various elements and associated transcription factors required for RNA polymerase to transcribe gene expression. Mediator complex subunit 12 (MED12) is part of the four-part cyclin-dependent kinase (CDK) module of Mediator, which also includes MED13, cyclin-dependent kinase 8 (CDK8), and cyclin C (CCNC). Mutations in MED12 have been associated with lymphoproliferative disorders (Kampjarvi et al., Oncotarget (2015) 6(3):1884-88). Recently, it has been observed that targeted deletion of MED12, CCNC or CDK8 in human CAR-T cells can increase cell proliferation, cytokine production and anti-tumor activity. In particular, MED12-deficient T cells show changes in genes that regulate effector T cell differentiation. See Freitas et al., Cancer Res (2022) 82 (12_suppl): 2822; and Freitas et al., Science (2022) 378 (6620): eabn5647. It is expected that reducing the level of MED12, MED13, CDK8 and / or CCNC can provide enhanced persistence for edited cells (such as NK cells), so that (when engineered according to the embodiments provided herein) the cytotoxicity to target tumor cells is enhanced.

[0288] Two other transcription factors (which are known key regulatory factors for T cell exhaustion) are also expected to become ideal targets in NK cells to destroy or otherwise reduce NK cell exhaustion. DNA binding inhibitor 3 (ID3) is known to be highly expressed in progenitor NK cells, but expression is reduced in mature cells (Boos et al., J Exp Med (2007) 204 (5): 1119-30). Therefore, in several embodiments, knocking out ID3 causes NK cells to present a more mature phenotype and activity, and / or reduce exhaustion. Similarly, in several embodiments, reducing the expression of SOX4 by gene editing reduces NK cell exhaustion (Good et al., Cell 184 (25): P6081-6100).

[0295] According to other embodiments, other regulatory factors of one or more aspects of NK cell (or T cell) function are regulated by gene editing. A variety of cytokines transmit negative (such as TGF-β mentioned above) or positive signals to immune cells. As a non-limiting example, IL-15 is a positive regulatory factor for NK cells, as disclosed herein, it can enhance one or more of NK cell homing, NK cell migration, NK cell expansion / proliferation, NK cell cytotoxicity and / or NK cell persistence. Under normal physiological conditions, in order to control NK cells, cytokine-induced SH2 domain-containing protein (CIS, encoded by CISH gene) acts as a key negative regulatory factor of IL-15 signal transduction in NK cells. As discussed herein, due to the multiple aspects of IL-15 biological characteristics affecting NK cell function, including but not limited to proliferation / amplification, activation, cytotoxicity, persistence, homing, migration, etc. Therefore, according to several embodiments, CISH is edited to enhance the function of NK cells in multiple functional aspects, thereby producing a more effective and lasting NK cell therapy. In several embodiments, CIS inhibitors are used in combination with the administration of engineered NK cells. In several embodiments, CIS expression is knocked down or eliminated by gene editing of the CISH gene (e.g., using CRISPR-Cas editing technology). In other embodiments, small interfering RNA, antisense RNA, TALEN, or zinc finger proteins are used. In some embodiments, CIS expression is knocked down in T cells by gene editing.
[0296] In several embodiments, as discussed above, the editing of CISH advantageously gives the edited cells (particularly edited NK cells) enhanced expansion capacity, cytotoxicity and / or persistence. In addition, in several embodiments, the modification of TCR includes modification of TCR α, but does not affect the signal transduction by the CD3 complex, thereby allowing T cell proliferation. In one embodiment, TCR α is inactivated by expressing pre-T α (pre-T α) in the cell, thereby restoring the functional CD3 complex in the absence of functional α / β TCR. As disclosed herein, non-allogeneic modified T cells are also engineered to express CAR to redirect the specificity of non-allogeneic reactive T cells to tumor markers, but are independent of MHC. In several embodiments, a combination of multiple editors is used, for example, as a non-limiting example, a combination of TCR and CISH knockout, or a combination of CISH knockout and CD47 knock-in. In some embodiments, a combination of CISH knockout and CDK8 knockout is used in combination. In some embodiments, a combination of CISH knockout and CCNC knockout is used in combination. In some embodiments, a combination of CISH knockout and MED12 knockout is used in combination. In some embodiments, a combination of CISH knockout and MED13 knockout is used in combination.
[0297] In several embodiments, CISH gene editing gives NK cells enhanced ability to home to target sites. In several embodiments, CISH gene editing gives NK cells enhanced migration ability, for example, in response to chemical attractants or away from repellents within the tissue for migration. In several embodiments, CISH gene editing gives NK cells enhanced ability to be activated, thereby exerting, for example, anti-tumor effects. In several embodiments, CISH gene editing gives NK cells enhanced proliferation ability, which, in several embodiments, makes it possible to generate a stable number of NK cells from a donor blood sample. In addition, in such embodiments, CISH is edited and engineered to express CAR NK cells in culture more easily, more firmly and more consistently amplified. In several embodiments, CISH gene editing gives NK cells enhanced cytotoxicity. In several embodiments, the editing of CISH synergistically enhances the cytotoxic effects of engineered NK cells and / or engineered T cells expressing CAR.
[0298] In several embodiments, CISH gene editing activates or inhibits multiple pathways. CIS protein is a negative regulator of IL-15 signaling, for example by inhibiting the JAK-STAT signaling pathway. These pathways typically result in the transcription of IL-15 response genes (including CISH). In several embodiments, knocking down CISH relieves the inhibition of JAK-STAT (such as JAK1-STAT5) signaling, thereby enhancing the transcription of IL-15 response genes. In several embodiments, knocking out CISH leads to enhanced signaling through the mammalian target of rapamycin (mTOR), while the expression of genes related to cell metabolism and respiration increases accordingly. In several embodiments, knocking out CISH leads to increased expression of IL-2Rα (CD25) induced by IL-15, but does not affect IL-15Rα or IL-2 / 15Rβ, enhances the binding of NK cell membranes to IL-15 and / or IL-2, increases the phosphorylation of STAT-3 and / or STAT-5, and increases the expression of anti-apoptotic proteins (such as Bcl-2). In several embodiments, knocking out CISH results in IL-15 induction of upregulation of selected genes associated with mitochondrial function (such as the electron transport chain and cellular respiration) and the cell cycle. Thus, in several embodiments, knocking out CISH by gene editing enhances the cytotoxicity and / or persistence of NK cells at least in part by metabolic reprogramming. In several embodiments, negative regulators of cellular metabolism (such as TXNIP) are downregulated due to CISH knockout. In several embodiments, after CISH knockout, promoters for cell survival and proliferation (including BIRC5 (survival protein), TOP2A, CKS2, and RACGAP1) are upregulated, while anti-proliferative or pro-apoptotic proteins (such as TGFB1, ATM, and PTCH1) are downregulated. In several embodiments, CISH knockout alters the signaling state (e.g., activates or inactivates signaling) by or through one or more of CXCL-10, IL-2, TNF, IFNγ, IL-13, IL-4, Jnk, PRF1, STAT5, PRKCQ, IL-2 receptor beta, SOCS2, MYD88, STAT3, STAT1, TBX21, LCK, JAK3, IL-8 receptor, ABL1, IL-9, STAT5A, STAT5B, Tcf7, PRDM1, and / or EOMES.
[0299] As a non-limiting example, TGF-β is a cytokine released by tumor cells that leads to immunosuppression within the tumor microenvironment. This immunosuppression reduces the ability of immune cells (or even engineered CAR immune cells in some cases) to destroy tumor cells, thereby allowing the tumor to progress. In several embodiments, as discussed in detail below, immune checkpoints are destroyed by gene editing. In several embodiments, blockers of immunosuppressive cytokines in the tumor microenvironment are used, including blocking their release or using competitive inhibitors to reduce the ability of signal molecules to bind and suppress immune cells. Such signal molecules include but are not limited to TGF-β, IL-10, arginase, inducible NOS, reactive-NOS, Arg1, indoleamine 2,3-dioxygenase (IDO) and PGE2. However, in other embodiments, immune cells (such as NK cells) are provided, wherein the responsiveness of NK cells (or other cells) to given immunosuppressive signal molecules is destroyed and / or eliminated. For example, in several embodiments, NK cells or T cells are gene edited to reduce their sensitivity to TGF-β. TGF-β is an inhibitor of NK cell function at least at the level of proliferation and cytotoxicity. Therefore, according to some embodiments, the expression of TGF-β receptor is knocked down or knocked out by gene editing, so that the edited NK cells are resistant to the immunosuppressive effects of TGF-β in the tumor microenvironment. In several embodiments, the TGFβ2 receptor is knocked down or knocked out by gene editing (for example, using CRISPR-Cas editing technology). In other embodiments, small interfering RNA, antisense RNA, TALEN or zinc finger protein are used. In some embodiments, other isoforms of TGF-β receptor (such as TGF-β1 and / or TGF-β3) are edited. In some embodiments, the TGF-β receptor in T cells is knocked down by gene editing.
[0300] Other cell engineering strategies are also provided herein to further enhance the persistence of allogeneic cell therapy products (such as allogeneic CAR-T cells and / or allogeneic CAR-NK cells). In several embodiments, provided herein are genetically engineered immune cell populations for cancer immunotherapy, wherein genetically engineered immune cells are genetically modified (such as gene editing) at one, two, three or more loci to enhance the cytotoxic activity, persistence or other properties of cells (such as NK cells and / or T cells).
[0301] As discussed herein, there are various strategies that can be used to reduce the propensity of allogeneic cell therapy products to induce host cell-mediated graft rejection. For example, in several embodiments, to reduce host-mediated graft rejection, the expression of B2M is reduced and / or eliminated. In several embodiments, one or more of the following B2M-specific guide RNAs are used to disrupt and / or knock out the expression of B2M using a CRISPR-Cas mediated approach (such as Cas9) or other guide nucleases disclosed elsewhere herein: SEQ ID 199-CGCGAGCACAGCTAAGGCCA; SEQ ID 200-GAGTAGCGCGAGCACAGCTA; SEQ ID 201-GCTACTCTCTCTTTCTGGCC; SEQ ID 202-GGCCGAGATGTCTCGCTCCG; SEQ ID 203-GGCCACGGAGCGAGACATCT; SEQ ID 204-CACAGCCCAAGATAGTTAAG; SEQ ID 205-AGTCACATGGTTCACACGGC; SEQ ID 206-AAGTCAACTTCAATGTCGGA; SEQ ID 207-ACTTGTCTTTCAGCAAGGAC; and SEQ ID 208-TGGGCTGTGACAAAGTCACA.
[0302] In several embodiments, gene editing reduces the transcription of B2M by about 30%, about 40%, about 50%, about 60%, about 70%, about 75%, about 80%, about 85%, about 90%, about 95%, about 97%, about 98%, about 99% or more (including any amount between the listed values). In several embodiments, gene editing reduces the transcription of B2M by at least about 30%; in several embodiments, gene editing reduces the transcription of B2M by at least about 40%; in several embodiments, gene editing reduces the transcription of B2M by at least about 50%; in several embodiments, gene editing reduces the transcription of B2M by at least about 60%; in several embodiments, gene editing reduces the transcription of B2M by at least about 70%; in several embodiments, gene editing reduces the transcription of B2M by at least about 80%; in several embodiments, gene editing reduces the transcription of B2M by at least about 90%.
[0303] In several embodiments, gene editing can reduce the expression of the target protein by about 30%, about 40%, about 50%, about 60%, about 70%, about 75%, about 80%, about 85%, about 90%, about 95%, about 97%, about 98%, about 99% or more (including any amount between the listed values). In several embodiments, gene editing reduces the expression of B2M by about 30%, about 40%, about 50%, about 60%, about 70%, about 75%, about 80%, about 85%, about 90%, about 95%, about 97%, about 98%, about 99% or more (including any amount between the listed values). In several embodiments, gene editing reduces the expression of B2M by at least about 30%; in several embodiments, gene editing reduces the expression of B2M by at least about 40%; in several embodiments, gene editing reduces the expression of B2M by at least about 50%; in several embodiments, gene editing reduces the expression of B2M by at least about 60%; in several embodiments, gene editing reduces the expression of B2M by at least about 70%; in several embodiments, gene editing reduces the expression of B2M by at least about 80%; and in several embodiments, gene editing reduces the expression of B2M by at least about 90%.
[0304] In several embodiments, to enhance the overall activation of the resulting T cells and / or NK cells or other cell types described herein, the expression of ADORA2A (adenosine 2a receptor) is reduced and / or eliminated. In several embodiments, ADORA2A is destroyed and / or knocked out using one or more gene editing methods disclosed herein. In several embodiments, CRISPR-Cas mediated methods (such as Cas9) or other guide nucleases disclosed elsewhere herein are used to guide nucleases using one or more of the following ADORA2A-specific guide RNAs (SEQ ID NO: 404-407) to destroy and / or knock out ADORA2A. In several embodiments, gene editing can reduce the expression of the target protein by about 30%, about 40%, about 50%, about 60%, about 70%, about 75%, about 80%, about 85%, about 90%, about 95%, about 97%, about 98%, about 99% or more (including any amount between the listed values). Loss of ADORA2A expression induces decreased sensitivity to adenosine, a recognized immunosuppressant for T cells and NK cells (Young et al., Cancer Res. (2018) 78(4):1003-16; Cekic and Linden, Cancer Res. (2014) 74(24):7239-49). In NK cells, loss of ADORA2A leads to loss of maturation, proliferation, and effector function (as shown in constitutive knockout mice). In T cells, loss of ADORA2A leads to loss of CD8 downstream activation and function, increase in Treg and TH2, and loss of TH1. Therefore, according to various embodiments, gene editing of ADORA2A can increase the cytotoxicity, persistence, immune evasion ability, or otherwise enhance the efficacy of engineered NK cells, T cells, or other cells as disclosed herein.
[0305] In several embodiments, gene editing reduces the transcription of ADORA2A by about 30%, about 40%, about 50%, about 60%, about 70%, about 75%, about 80%, about 85%, about 90%, about 95%, about 97%, about 98%, about 99% or more (including any amount between the recited values). In several embodiments, gene editing reduces the transcription of ADORA2A by at least about 30%; in several embodiments, gene editing reduces the transcription of ADORA2A by at least about 40%; in several embodiments, gene editing reduces the transcription of ADORA2A by at least about 50%; in several embodiments, gene editing reduces the transcription of ADORA2A by at least about 60%; in several embodiments, gene editing reduces the transcription of ADORA2A by at least about 70%; in several embodiments, gene editing reduces the transcription of ADORA2A by at least about 80%; in several embodiments, gene editing reduces the transcription of ADORA2A by at least about 90%.
[0306] In several embodiments, gene editing can reduce the expression of the target protein by about 30%, about 40%, about 50%, about 60%, about 70%, about 75%, about 80%, about 85%, about 90%, about 95%, about 97%, about 98%, about 99% or more (including any amount between the listed values). In several embodiments, gene editing reduces the expression of ADORA2A by about 30%, about 40%, about 50%, about 60%, about 70%, about 75%, about 80%, about 85%, about 90%, about 95%, about 97%, about 98%, about 99% or more (including any amount between the listed values).

[0307] As its name implies, the tumor microenvironment (TME) is the environment surrounding the tumor, including the surrounding blood vessels and capillaries, immune cells circulating or resident in the area, fibroblasts, tumor cells, various signaling molecules released by immune cells or other cells in the area, and the surrounding extracellular matrix. Tumors use various mechanisms to evade detection and / or destruction by host immune cells, including changes to the tumor microenvironment. Tumors can modify the tumor microenvironment by releasing extracellular signals, promoting tumor angiogenesis, and even inducing immune tolerance, in part by restricting the entry of immune cells into the tumor microenvironment and / or restricting the proliferation / expansion of immune cells in the tumor microenvironment. Tumors can also modify the extracellular matrix (ECM), which can create pathways for tumor extravasation to new sites. Transforming growth factor-β (TGF-β) has beneficial effects in reducing inflammation and preventing autoimmunity. However, it can also inhibit antitumor immune responses, and therefore, upregulated expression of TGFb has been associated with tumor progression and metastasis (Pickup et al., Nat. Rev. Cancer (2013) 13(11):788-99). For example, TGF-β signaling can inhibit the cytotoxic function of NK cells by interacting with TGF-β receptors expressed by NK cells, such as TGF-β receptor isoform II (TGFBR2). According to multiple embodiments disclosed herein, reducing or eliminating the expression of TGFBR2 by gene editing (e.g., CRISPR / Cas9 guided by TGFBR2 guide RNA) blocks the inhibitory effect of TGF-β on NK cells.
[0308] In several embodiments, to enhance the overall activation of the resulting T cells and / or NK cells or other cell types disclosed herein, the expression of TGFBR2 is reduced and / or eliminated. In several embodiments, one or more gene editing methods disclosed herein are used to destroy and / or knock out TGFBR2. Table 6 below provides non-limiting examples of guide RNAs for reducing and / or eliminating TGFBR2 expression. Table 6: TGFβ receptor type 2 isoform guide RNAs SEQ ID NO: name sequence target 147 TGFBR2-1 CCCCTACCATGACTTTATTC Exon 4 148 TGFBR2-2 ATTGCACTCATCAGAGCTAC Exon 4 149 TGFBR2-3 AGTCATGGTAGGGGAGCTTG Exon 4 150 TGFBR2-4 TGCTGGCGATACGCGTCCAC Exon 1 151 TGFBR2-5 GTGAGCAATCCCCCGGGCGA Exon 4 152 TGFBR2-6 AACGTGCGGTGGGATCGTGC Exon 1
[0309] In several embodiments, TGFBR2 is disrupted and / or knocked out using a CRISPR-Cas mediated approach (such as Cas9) or other guide nucleases disclosed elsewhere herein, using one or more of the following TGFBR2-specific guide RNA-guided nucleases: sequences of SEQ ID NOs: 445-448.
[0310] In several embodiments, gene editing reduces transcription of TGFBR2 by about 30%, about 40%, about 50%, about 60%, about 70%, about 75%, about 80%, about 85%, about 90%, about 95%, about 97%, about 98%, about 99%, or more (including any amount between the recited values). In several embodiments, gene editing reduces transcription of TGFBR2 by at least about 30%; in several embodiments, gene editing reduces transcription of TGFBR2 by at least about 40%; in several embodiments, gene editing reduces transcription of TGFBR2 by at least about 50%; in several embodiments, gene editing reduces transcription of TGFBR2 by at least about 60%; in several embodiments, gene editing reduces transcription of TGFBR2 by at least about 70%; in several embodiments, gene editing reduces transcription of TGFBR2 by at least about 80%; in several embodiments, gene editing reduces transcription of TGFBR2 by at least about 90%.
[0311] In several embodiments, gene editing can reduce the expression of the target protein by about 30%, about 40%, about 50%, about 60%, about 70%, about 75%, about 80%, about 85%, about 90%, about 95%, about 97%, about 98%, about 99% or more (including any amount between the listed values). In several embodiments, gene editing reduces the expression of TGFBR2 by about 30%, about 40%, about 50%, about 60%, about 70%, about 75%, about 80%, about 85%, about 90%, about 95%, about 97%, about 98%, about 99% or more (including any amount between the listed values). In several embodiments, gene editing reduces the expression of TGFBR2 by at least about 30%; in several embodiments, gene editing reduces the expression of TGFBR2 by at least about 40%; in several embodiments, gene editing reduces the expression of TGFBR2 by at least about 50%; in several embodiments, gene editing reduces the expression of TGFBR2 by at least about 60%; in several embodiments, gene editing reduces the expression of TGFBR2 by at least about 70%; in several embodiments, gene editing reduces the expression of TGFBR2 by at least about 80%; and in several embodiments, gene editing reduces the expression of TGFBR2 by at least about 90%.
[0312] In NK cells, TGFBR2 is a key checkpoint in NK cell-mediated tumor immunity, and for T cells, knocking out TGFBR2 can rescue CAR-T cell exhaustion induced by TGF-β1 (Tang et al., JCI Insight (2020) 5(4):e133977). Therefore, according to various embodiments, gene editing of TGFBR2 increases the cytotoxicity, persistence, or otherwise enhances the efficacy of engineered NK cells, T cells, or other cells disclosed herein.
[0313] According to additional embodiments, the expression of receptors, signaling pathways or proteins on immune cells is destroyed or eliminated, which can lead to enhanced activity of immune cells against target cancer cells (such as cytotoxicity, persistence, etc.). In several embodiments, this is because the inhibitory effect of immune cells is lifted. Natural killer cells express a variety of receptors, especially those in the natural killer cell family 2 receptor. According to multiple embodiments disclosed herein, one such receptor (NKG2D receptor) is used to generate a cytotoxic signaling construct expressed by NK cells, thereby enhancing the anti-cancer activity of such NK cells. In addition, NK cells express NKG2A receptors, which are inhibitory receptors. One mechanism by which tumors become resistant to immune cells is through the expression of class I histocompatibility complex molecules (HLA-E) loaded with peptides, which inhibit the activity of NK cells through the connection of HLA-E to NKG2A receptors. Therefore, although one method may be to block the interaction of HLA-E with the NKG2A receptor expressed on NK cells, according to multiple embodiments disclosed herein, the expression of NKG2A is destroyed, which short-circuits this inhibitory pathway, thereby enhancing the cytotoxicity of NK cells.
[0314] Table 7 below provides non-limiting examples of guide RNAs for reducing and / or eliminating NKG2A expression. Table 7: NKG2A guide RNA SEQ ID NO: name sequence target 158 NKG2A-1 GGAGCTGATGGTAAATCTGC Exon 4 159 NKG2A-2 TTGAAGGTTTAATTCCGCAT Exon 3 160 NKG2A-3 AACAACTATCGTTACCACAG Exon 4
[0315] In several embodiments, NKG2A is disrupted and / or knocked out using CRISPR-Cas mediated methods (such as Cas9) or other guide nucleases disclosed elsewhere herein using one or more of the following NKG2A-specific guide RNA-guided nucleases: sequences of SEQ ID NOs: 450-452.
[0316] In several embodiments, gene editing reduces the transcription of NKG2A by about 30%, about 40%, about 50%, about 60%, about 70%, about 75%, about 80%, about 85%, about 90%, about 95%, about 97%, about 98%, about 99% or more (including any amount between the listed values). In several embodiments, gene editing reduces the transcription of NKG2A by at least about 30%. In several embodiments, gene editing reduces the transcription of NKG2A by at least about 40%. In several embodiments, gene editing reduces the transcription of NKG2A by at least about 50%. In several embodiments, gene editing reduces the transcription of NKG2A by at least about 60%. In several embodiments, gene editing reduces the transcription of NKG2A by at least about 70%. In several embodiments, gene editing reduces the transcription of NKG2A by at least about 80%. In several embodiments, gene editing reduces the transcription of NKG2A by at least about 90%.
[0317] In several embodiments, gene editing can reduce the expression of the target protein by about 30%, about 40%, about 50%, about 60%, about 70%, about 75%, about 80%, about 85%, about 90%, about 95%, about 97%, about 98%, about 99% or more (including any amount between the listed values). In several embodiments, gene editing reduces the expression of NKG2A by about 30%, about 40%, about 50%, about 60%, about 70%, about 75%, about 80%, about 85%, about 90%, about 95%, about 97%, about 98%, about 99% or more (including any amount between the listed values). In several embodiments, gene editing reduces the expression of NKG2A by at least about 30%. In several embodiments, gene editing reduces the expression of NKG2A by at least about 40%. In several embodiments, gene editing reduces the expression of NKG2A by at least about 50%. In several embodiments, gene editing reduces NKG2A expression by at least about 60%. In several embodiments, gene editing reduces NKG2A expression by at least about 70%. In several embodiments, gene editing reduces NKG2A expression by at least about 80%. In several embodiments, gene editing reduces NKG2A expression by at least about 90%.
[0318] NKG2A binds to HLA-E and is considered a receptor that recognizes MHC. Since NKG2A is an inhibitory receptor, the loss of NKG2A expression induces increased activation of constitutive cells. In NK cells and T cells, the loss of NKG2A leads to increased activation and cytotoxicity against tumor cells expressing HLA-E (Kamiya et al., J. Clin. Invest. (2019) 129 (5): 2094-2106). Therefore, according to various embodiments, gene editing of NKG2A increases the cytotoxicity and persistence of engineered NK cells, T cells, or other cells disclosed herein, or otherwise enhances their efficacy.
[0319] Interleukins, especially interleukin-15, are important in the function and survival of NK cells. Suppressor of cytokine signaling (SOCS) is a negative regulator of NK cell cytokine release. Protein tyrosine phosphatase CD45 is an important regulator of NK cell activity through Src family kinase activity. CD45 expression is involved in immunoreceptor tyrosine activation motif (ITAM)-specific NK cell function and degranulation, cytokine production and amplification processes (Hesslein et al., Blood (2011) 117 (11): 3087-95). Therefore, knocking out the expression of CD45 should lead to weakened NK cell function. As described above, CRISPR / Cas9 is used to destroy the expression of CD45 (encoded by PTPRC) and SOCS2, but in other embodiments, other gene editing methods may also be used. Non-limiting examples of guide RNAs targeting CD45 and SOCS2 are shown in Table 8 below.

[0330] Cbl-b is an E3 ubiquitin ligase that negatively regulates T cell activation. Loss of Cbl-b expression in NK cells and T cells has been shown to enhance anti-tumor immunity. In addition, Cbl-b-deficient T cells and NK cells are resistant to PD-L1 / PD-1-mediated inhibition (Fujiwara et al., Front. Immunol. (2017) 8:42). Therefore, according to various embodiments, Cbl-b is genetically edited to increase the cytotoxicity and persistence of engineered NK cells, T cells, or other cells as disclosed herein, or to otherwise enhance their efficacy.
[0331] Another E3 ubiquitin ligase (triplet motif-containing protein 29 (TRIM29)) is a negative regulator of NK cell function (Dou et al., J. Immunol. (2019) 203 (4): 873-80). Resting NK cells do not usually express TRIM29, but are easily upregulated after activation (especially by IL-12 / IL-18 stimulation). Non-limiting examples of guide RNAs targeting TRIM29 for reducing and / or eliminating TRIM29 expression are shown in Table 10 below.

In several embodiments, gene editing reduces the expression of TRIM29 by at least about 30%. In several embodiments, gene editing reduces the expression of TRIM29 by at least about 40%. In several embodiments, gene editing reduces the expression of TRIM29 by at least about 50%. In several embodiments, gene editing reduces the expression of TRIM29 by at least about 60%.

In several embodiments, gene editing reduces B2M expression by at least about 90%.
[0337] Loss of B2-microglobulin expression leads to a substantial reduction in the levels of MHC class I molecules, and in NK cells and T cells, the reduction of B2-microglobulin can modulate overall cellular recognition of autologous and allogeneic cells. Thus, according to several embodiments, genetic editing of B2-microglobulin enhances the cytotoxicity, persistence, and / or otherwise enhances the efficacy of the engineered NK cells, T cells, or other cells disclosed herein.
[0338] In several embodiments, in order to enhance the overall activation of the resulting T cells and / or NK cells or other cell types described herein, the expression of T cell immune receptor (TIGIT) with Ig and ITIM domains is reduced and / or eliminated.

[0340] In several embodiments, gene editing can reduce the expression of the target protein by about 30%, about 40%, about 50%, about 60%, about 70%, about 75%, about 80%, about 85%, about 90%, about 95%, about 97%, about 98%, about 99% or more (including any amount between the listed values). In several embodiments, gene editing reduces the expression of TIGIT by about 30%, about 40%, about 50%, about 60%, about 70%, about 75%, about 80%, about 85%, about 90%, about 95%, about 97%, about 98%, about 99% or more (including any amount between the listed values).

In several embodiments, gene editing reduces the expression of TIGIT by at least about 90%.
[0341] TIGIT is a checkpoint receptor associated with T cell and NK cell exhaustion. Loss of TIGIT expression in NK cells prevents NK cell exhaustion and promotes NK cell-dependent tumor immunity (Zhang et al., Nat. Immunol. (2018) 19(7): 723-32). Loss of TIGIT expression in T cells similarly leads to downstream activation of the resulting T cells. Therefore, according to multiple embodiments, gene editing of TIGIT increases the cytotoxicity, persistence, or otherwise enhances the efficacy of engineered NK cells, T cells, or other cells described herein.
[0342] In several embodiments, to enhance the overall activation of obtained T cells and / or NK cells or other cell types disclosed herein, the expression of programmed cell death protein -1 (PD-1, encoded by PDCD1) is reduced and / or eliminated. In several embodiments, PD-1 is destroyed and / or knocked out using one or more gene editing methods disclosed herein. In several embodiments, PD-1 is destroyed and / or knocked out using CRISPR-Cas mediated methods (such as Cas9) or other guide nucleases disclosed elsewhere herein, by utilizing the following one or more PD-1 specific guide RNA-guided nucleases to destroy and / or knock out PD-1: SEQ ID NO: 412-415.
[0343] In several embodiments, gene editing reduces the transcription of PDCD1 by about 30%, about 40%, about 50%, about 60%, about 70%, about 75%, about 80%, about 85%, about 90%, about 95%, about 97%, about 98%, about 99% or more (including any amount between the listed values).

[0344] In several embodiments, gene editing can reduce the expression of the target protein by about 30%, about 40%, about 50%, about 60%, about 70%, about 75%, about 80%, about 85%, about 90%, about 95%, about 97%, about 98%, about 99% or more (including any amount between the listed values). In several embodiments, gene editing reduces the expression of PD-1 by about 30%, about 40%, about 50%, about 60%, about 70%, about 75%, about 80%, about 85%, about 90%, about 95%, about 97%, about 98%, about 99% or more (including any amount between the listed values). In several embodiments, gene editing reduces the expression of PD-1 by at least about 30%. In several embodiments, gene editing reduces the expression of PD-1 by at least about 40%.

[0345] PD-1 plays an inhibitory role in immune regulation and downregulates overall function by suppressing immune cell activity. The loss of PD-1 expression in NK cells increases overall cytotoxicity due to increased secretion of interferon-γ, granzyme B, and perforin (Niu et al., Int. J. Med. Sci. (2020) 17 (13): 1964-73). Similarly, T cells with lost PD-1 expression show increased cytotoxicity and increased overall activation of caspase (caspase) (Zhao et al., Ocotarget (2018) 9 (4): 5208-15). Therefore, according to multiple embodiments, PD-1 is genetically edited to increase the cytotoxicity, persistence, or otherwise enhance the efficacy of engineered NK cells, T cells, or other cells disclosed herein.
[0346] In several embodiments, to enhance the overall activation of the resulting T cells and / or NK cells or other cell types disclosed herein, the expression of T cell immunoglobulin and mucin domain-3 (TIM-3, also known as HAVCR2) is reduced and / or eliminated.

In several embodiments, gene editing reduces the transcription of TIM3 by at least about 70%. In several embodiments, gene editing reduces the transcription of TIM3 by at least about 80%. In several embodiments, gene editing reduces the transcription of TIM3 by at least about 90%.
[0348] In several embodiments, gene editing can reduce the expression of the target protein by about 30%, about 40%, about 50%, about 60%, about 70%, about 75%, about 80%, about 85%, about 90%, about 95%, about 97%, about 98%, about 99% or more (including any amount between the listed values).

In several embodiments, gene editing reduces the expression of TIM-3 by at least about 30%. In several embodiments, gene editing reduces the expression of TIM-3 by at least about 40%. In several embodiments, gene editing reduces the expression of TIM-3 by at least about 50%. In several embodiments, gene editing reduces TIM-3 expression by at least about 60%. In several embodiments, gene editing reduces TIM-3 expression by at least about 70%. In several embodiments, gene editing reduces TIM-3 expression by at least about 80%. In several embodiments, gene editing reduces TIM-3 expression by at least about 90%.
[0349] TIM-3 is an inhibitory receptor involved in immune checkpoint function. Loss of TIM-3 expression increases the overall cytotoxicity of engineered NK cells and T cells and reduces the exhaustion of NK cells and T cells, thereby improving the effector function of component cells lacking TIM-3 expression (Pires de Silva et al., Cancer Imunol. Res. (2014) 2 (5): 410-22). Therefore, according to multiple embodiments, TIM-3 is genetically edited to increase the cytotoxicity, persistence, immune evasion ability of engineered NK cells, T cells, or other cells disclosed herein, or to otherwise enhance their efficacy.
[0350] In several embodiments, to enhance the overall activation of the resulting T cells and / or NK cells or other cell types disclosed herein, the expression of CD38 is reduced and / or eliminated. In several embodiments, CD38 is destroyed and / or knocked out using one or more gene editing methods disclosed herein. In several embodiments, CD38 is destroyed and / or knocked out using CRISPR-Cas mediated methods (such as Cas9) or other guide nucleases disclosed elsewhere herein by utilizing one or more of the following CD38-specific guide RNAs to guide nucleases: SEQ ID NOs: 420-423.
[0351] In several embodiments, gene editing reduces the transcription of CD38 by about 30%, about 40%, about 50%, about 60%, about 70%, about 75%, about 80%, about 85%, about 90%, about 95%, about 97%, about 98%, about 99% or more (including any amount between the listed values). In several embodiments, gene editing reduces the transcription of CD38 by at least about 30%. In several embodiments, gene editing reduces the transcription of CD38 by at least about 40%. In several embodiments, gene editing reduces the transcription of CD38 by at least about 50%. In several embodiments, gene editing reduces the transcription of CD38 by at least about 60%.

In several embodiments, gene editing reduces the transcription of CD38 by at least about 90%.
[0352] In several embodiments, gene editing can reduce the expression of the target protein by about 30%, about 40%, about 50%, about 60%, about 70%, about 75%, about 80%, about 85%, about 90%, about 95%, about 97%, about 98%, about 99% or more (including any amount between the listed values). In several embodiments, gene editing reduces the expression of CD38 by about 30%, about 40%, about 50%, about 60%, about 70%, about 75%, about 80%, about 85%, about 90%, about 95%, about 97%, about 98%, about 99% or more (including any amount between the listed values). In several embodiments, gene editing reduces the expression of CD38 by at least about 30%. In several embodiments, gene editing reduces the expression of CD38 by at least about 40%. In several embodiments, gene editing reduces the expression of CD38 by at least about 50%. In several embodiments, gene editing reduces CD38 expression by at least about 60%.

In several embodiments, gene editing reduces CD38 expression by at least about 90%.
[0353] CD38 plays a role in the maturation cycle of immune cells, and blood cancers often show upregulation of CD38. The loss of CD38 expression on constitutive NK cells can achieve stronger cytotoxicity due to reduced fratricide (Nagai et al., Blood (2019) 134 (suppl. 1): 870). Wild-type NK cells themselves express CD38, which leads to downstream self-targeting effects in wild-type NK cells. For T cells, the loss of constitutive T cell CD38 expression leads to increased cytotoxicity. Therefore, according to multiple embodiments, gene editing of CD38 increases the cytotoxicity, persistence, or otherwise enhances the efficacy of the engineered NK cells, T cells, or other cells disclosed herein.
[0354] In several embodiments, to enhance the overall activation of the obtained T cells and / or NK cells or other cell types provided herein, the expression of T cell receptor alpha (TCR alpha) is reduced and / or eliminated.

[0357] The T cell receptor (TCR) is a protein complex on T cells that is responsible for recognizing major histocompatibility complex (MHC) molecules. The loss of certain TCRs and the preferential expression of other TCRs can lead to increased cytotoxicity of engineered cells due to enhanced selective targeting and recognition of the constituent cells. Therefore, according to various embodiments, gene editing of TCRs can increase the cytotoxicity, persistence, or otherwise enhance the efficacy of engineered NK cells, T cells, or other cells as disclosed herein.
[0358] Cytokine-induced SH2 domain protein (CIS) is a negative regulator of the IL-15 signaling pathway in natural killer (NK) cells and is encoded by the CISH gene in humans. The IL-15 signaling pathway has a positive effect on the amplification, survival, cytotoxicity and cytokine production of NK cells. Therefore, the destruction of CISH can make NK cells more sensitive to IL-15, thereby enhancing their anti-tumor effects. In several embodiments, to enhance the overall activation of the obtained T cells and / or NK cells or other cell types provided herein, the expression of CISH is reduced and / or eliminated. In the experiments described herein, it was observed that although the destruction (such as knocking out) MED12 can increase the cytotoxicity of NK cells, it also tends to reduce the proliferation capacity of such cells. However, it was surprisingly found that the effect of MED12 destruction on proliferation can be rescued by destroying (such as knocking out) CISH. Therefore, in some aspects, it is encompassed that MED12 and CISH are knocked out simultaneously in immune cells (such as NK cells). In some embodiments, gene editing is performed on a target sequence in the MED12 gene and a target sequence in the CISH gene of an immune cell, wherein the editing results in reduced expression and / or function of CIS and MED12 proteins encoded by the CISH and MED12 genes, respectively, compared to immune cells in which the target sequences have not been edited.
[0359] In several embodiments, one or more gene editing methods disclosed herein are used to disrupt and / or knock out CISH. Non-limiting examples of guide RNAs targeting CISH for reducing and / or eliminating expression of CIS (a protein encoded by CISH) are shown in Table 11 below.

In several embodiments, gene editing reduces the expression of CISH by about 30%, about 40%, about 50%, about 60%, about 70%, about 75%, about 80%, about 85%, about 90%, about 95%, about 97%, about 98%, about 99% or more (including any amount between the listed values).

[0363] In CD8+ T cells, CISH actively inhibits T cell receptor (TCR) signaling to maintain tumor tolerance, and CISH has been shown to be a downstream negative regulator of IL-15 receptor signaling (Palmer et al., J. Exp. Med. (2015) 212 (12): 2095-2113). In NK cells and T cells, CISH plays a role in checkpoint maturation and proliferation (Delconte et al., Nature Immunol (2016) 17: 816-24). Therefore, according to various embodiments, CISH is gene-edited to increase the cytotoxicity, persistence, or otherwise enhance the efficacy of engineered NK cells, T cells, or other cells described herein.

[0367] CEACAM1 is an immune checkpoint in NK cells and T cells that inhibits lysis of tumor cell lines expressing CEACAM1. Loss of CEACAM1 expression can increase the overall cytotoxicity of NK and T cells (Markel et al., J. Clin. Oncol. (2016) 34(suppl. 15):3044). Therefore, according to various embodiments, gene editing of CEACAM1 can increase the cytotoxicity, persistence, or otherwise enhance the efficacy of engineered NK cells, T cells, or other cells described herein.
