[0031] In this study, NK cells were initially found to be different from other components of the innate immune compartment. The behavior of NK cells was characterized by their antitumor function and anti-allogeneic cell lysis function. The countless immune receptors that exert control are illustrated in Figure 1 as a "shipper" graph. Gunal signaling molecules can be broadly classified into two main groups: activating and inhibitory. Based on their structure and mode of signaling, these categories further relate to immune receptors. They can be divided into families. The membrane proteome of NK cells is not yet fully understood. Functional redundancy within the NK cell "zipper" is a complex and dynamic interaction between complementary and antagonistic pathways. It was used to regulate cell lysis while maintaining a delicate balance.

[0032] Therefore, certain embodiments of this disclosure are intended for clinical applications of cell therapy and immunotherapy. Methods for the production, expansion, quality control, and functional characterization of bed-grade NK cells and The composition is provided. A clinically reasonable number of units for injection into a patient while meeting time constraints. Proliferating and forming NK cells is difficult even under ideal conditions. In this disclosure, the methods and compositions are technical processes for producing NK cells, and the achievable N Detailed description and dynamics of K cell expansion, as well as molecular characterization to verify the success of cell formation. This will be explained in detail.

[0033] In further embodiments, human natural killer (NK) cells are conditioned against tumors. , specifically as universal antigen-presenting cells (UAPCs) for formation and weaponization A robust platform technology that will be implemented is provided herein. "UAPC" is In this specification, the following are described as being designed for the optimized expansion of immune cells such as NK cells. This refers to antigen-presenting cells. This UAPC is used to overcome inhibitory signals, and NK cells To induce optimal and specific cell-killing function, a unique combination of co-stimulatory molecules is used. Therefore, it was created. From large-scale trials, UAPC was found to improve the mechanism of NK cells and tumors. It was shown that the disappearance could be fine-tuned. This UAPC is used in NK cell-mediated cancer immunotherapy. It is possible.

[0034] An example APC is the NK cell-sensitive K562 antigen-presenting cell line (APC) (clone 46 (referred to as) membrane-bound interleukin 21 (mbIL-21) and 4-1B It is produced by forced expression of B ligand. In another embodiment, in K562 cells m By forcibly expressing bIL-21, 4-1BB ligand, and CD48, UAP C was fabricated (called Universal APC (UAPC)). In another embodiment, K5 Forced expression of mbIL-21, 4-1BB ligand, and CS1 in 62 cells. They created a UAPC (called UAPC2) using mbI. L-21, 41BBL, and NK cell-specific antigens (e.g., SLAM family antigens (Table) 1)) can be produced to express

[0035] The UAPC platform uses T cells (e.g., alpha-beta and gamma-del). It can also be applied to expand other immune effectors, including T cells. These immune cells (e.g., NK cells and T cells) are found in peripheral blood, umbilical cord blood, bone marrow, or stem cells. These immune cells may originate from (including induced pluripotent stem cells). These immune cells are used in clinical applications such as cancer immunotherapy. The amount of UAPC required for cultivation to reach a meaningful number for a suitable application It can be used for expansion and activation in xobiotics.

Autoantigens can originate from host cells, or are usually derived from host cells. It originates from symbiotic organisms such as microorganisms that form colonies on the mucous membrane surface (known as symbiotic organisms). obtain.

[0043] To “treat” a disease or condition, or such treatment, means treating the signs or symptoms of that disease. The implementation of a protocol that may include administering one or more drugs to a patient for the purpose of alleviating symptoms. This refers to the following. The desired effects of the treatment include slowing the progression of the disease and improving the disease state. This includes reducing or alleviating symptoms, and achieving remission or improving the prognosis. Reducing symptoms means... It can occur before the onset of signs or symptoms of a disease or condition, and after they have appeared. Therefore, “to treat” or “treatment” means “to prevent” a disease or undesirable condition. " or may include the "prevention" of those. Furthermore, "to treat" or "treatment" may include signs Furthermore, complete relief of symptoms is not required, nor is a cure necessary; specifically, the patient has limitations.

Cancer treatment refers to the survival time of a subject with cancer. It can also refer to an extension of that.

[0045] "Subject" and "patient" refer to human or non-human (e.g., primates, mammals and This refers to vertebrates. In certain embodiments, the subject is a human.

[0046] The phrase "pharmaceutically or pharmacologically acceptable" means that it can be administered to animals such as humans as necessary. When used, the molecular entities do not cause side effects, allergic reactions, or other adverse reactions. This refers to the composition. The preparation of a pharmaceutical composition containing antibodies or further active ingredients is the process described above. In light of the indication, this is common knowledge to those skilled in the art. Furthermore, in the case of administration to animals (e.g., humans), The product must comply with the FDA Office of Biological Standards. It must meet the required standards for sterility, pyrogenicity, overall safety, and purity. This is understood.

[0047] As used herein, “pharmaceutically acceptable carrier” means “a carrier known to those skilled in the art.” Any and all aqueous solvents (e.g., water, alcohol solution / water-soluble) may be used. Liquid, saline solution, parenteral vehicle, e.g., sodium chloride, Ringer's dextrose (and), non-aqueous solvents (for example, propylene glycol, polyethylene glycol, vegetable oil and Injectable organic esters (e.g., ethyl oleate), dispersion media, coatings, interfaces Activators, antioxidants, preservatives (e.g., antibacterial or antifungal agents, antioxidants, chelating agents) (and inert gases), isotonic agents, absorption retarders, salts, drugs, drug stabilizers, gels, binders, excipients Agents, disintegrants, lubricants, sweeteners, flavorings, colorants, fluids and nutritional supplements, and the like. This includes various materials and combinations. The pH and accuracy of various components in the pharmaceutical composition. The concentration is adjusted according to well-known parameters.

[0048] The term "haplotyping or tissue typing" refers, for example, to the lymphatic system of a specific subject. To determine which HLA loci (or multiple loci) are expressed on the sphere. The method used to identify the haplotype or tissue type of a subject. This refers to the HLA gene, which is located in the major histocompatibility complex, a region on the short arm of chromosome 6. They are located in the body (MHC) and are involved in intercellular interactions, immune responses, organ transplantation, cancer development, and It is related to susceptibility to disease. There are six important gene loci in transplantation, including HLA-A. These were named HLA-B, HLA-C, HLA-DR, HLA-DP, and HLA-DQ. Each gene locus can contain one of several different alleles.

[0049] A widely used method for haplotyping is polymerase chain reaction (PCR). Using this method, we compare known segments of the gene encoding the MHC antigen with the DNA of the subject. The diversity in these regions of those genes indicates the tissue type or haplogroup of the subject. Determine the prognosis. Serological methods are also used to detect serologically defined antigens on the cell surface. It is used for the following purposes. HLA-A, -B, and -C determinants are measured by known serological methods. It is possible. In short, lymphocytes derived from the subject (isolated from fresh peripheral blood) are known to be used. Incubate these cells with antiserum that recognizes all HLA antigens. Spread the cells in a tray with microwells containing various types of antiserum. Incubate the cells for 30 minutes. After incubation, the incubation is supplemented for another 60 minutes. Lymphocytes are then subjected to anti- If a lymphocyte has an antigen on its surface that is recognized by antibodies in the serum, that lymphocyte is lysed. By adding a dye, changes in cell membrane permeability and cell death can be observed. The pattern of cells destroyed by the solution indicates the degree of histological incompatibility. For example, HL Lymphocytes derived from a certain individual being tested for A-A3 have shown anti-hemorrhagic effects against HLA-A3. If the antigen is destroyed in a well containing the solution, the test will be positive for this group of antigens.

[0050] The term "antigen-presenting cell (APC)" refers to a cell recognized by specific effector cells of the immune system. It is possible to present one or more antigens in the form of a peptide-MHC complex, and therefore This means that the cell can induce an effective cellular immune response to the presented antigen. This refers to a whole cell (e.g., macrophage). The term "APC" refers to an intact whole cell (e.g., macrophage). (B cells, endothelial cells, activated T cells and dendritic cells), or cells that can present antigens. These are naturally occurring or synthetic molecules (for example, complexed with y2-microglobulin). It includes purified MHC class I molecules. II. Universal antigen-presenting cells

[0051] Some embodiments of this disclosure relate to the production of universal antigen-presenting cells (UAPCs) and Regarding use: UAPC is for the expansion of immune cells (e.g., NK cells and T cells). It can be used. UAPC is membrane-bound IL-21 (mbIL-21) and 41BBL( It can be manipulated to express the CD137 ligand.

[0052] UAPC expresses CD137 ligand and / or membrane-bound cytokines. It can be manipulated. The membrane-bound cytokine can be mRNA-21 or mRNA-15. In certain embodiments, UAPC expresses CD137 ligand and mIL-21. It is manipulated to do so. APCs can originate from cancer cells such as leukemia cells. APCs are internal None of the resident HLA class I, II, or CD1d molecules may be expressed. AP C may express ICAM-1 (CD54) and LFA-3 (CD58). In particular, A PCs are designed to express K562 cells (for example, CD137 ligand and mRNA-21). (K562 cells that have been manipulated) APC may be irradiated. The above manipulation is performed in the said part This could be any method known in the field, such as the introduction of a retrovirus.

[0053] Cytokines exert very potent regulatory effects on all classes of immune cells (including NK cells). It exerts its influence on cell fate, activity, and the effectiveness of cellular responses. It activates NK cells. The power of cytokine stimulation lies in the fact that these "natural" effector functions are highly sensitive to environmental interventions. Being receptive and priming can control the behavior of NK cells in vivo. This supports the point.

[0054] To address the problem of obtaining a clinically valid amount of NK cells, this method is used in this U Interlo is used as a driving substance for NK cell expansion in APC platform technology. Ikin (IL-21) can be used. In humans, NK cells are induced by IL-10 and IL-21. Cellular stimulation induces NKG2D expression in a STAT3-dependent manner. Cytokine receptor However, many immune cells share similar cellular signaling components, but NK cells Specific signaling is dependent on the IL-21 receptor-STAT3 relationship for proliferation. To exist.

[0055] Cytokine signaling is crucial for maintaining lymphocyte survival and proliferation. In vivo, IL-2 administration is the only treatment approved by the FDA to enlarge NK cells. This is the method. Another potent NK cell activator, IL-15, is a promising alternative to IL-2. Although it is currently undergoing Phase I clinical trials as an alternative, it has shown significant toxicity after systemic administration. In addition to significant toxicity, these cytokines limit the persistence of NK cells, It also induces T cell proliferation. Despite sharing the same receptor for signal transduction, IL-2, IL-4, IL-7, IL-9, IL-15 and IL-21 receptors This has different and specific effects on various types of cells. A. Membrane-bound IL-21

[0056] In a specific embodiment, this UAPC is created to specifically activate NK cells. IL-21 may be used for this purpose. The IL-21 receptor (IL21R) is common. Cytokine receptor gamma chain (transmits signals through dimerization with gamma(c)) It has a close relationship with the IL-2 receptor beta chain, which can activate human NK cells. Type I cytokines are upregulated in cells that are ready to be stimulated. IL-21 can regulate the functions of T cells, B cells, and NK cells, but this study found that Only human NK cells show significant expansion through activation of the IL21 receptor signaling pathway. They found that this caused (i.e., a 1000-fold increase over 21 days). Conversely, IL21 CD8 + It plays an important role in the reduction of T cells.

[0057] IL21R signaling is primarily driven by STAT3, a highly potent cell proliferation activator. This is promoted by the IL21R-STAT3 relationship, which was investigated using an anti-phosphotyrosine antibody. GAS and cis-inducible markers are verified by immunoprecipitation and Western blotting. Driven by IL-21-inducible STAT3 DNA binding to the element. IL21 The molecular basis of the proliferation mediated by IL-21 is STAT1 and It is tyrosine 510 (Y510) on IL21R that mediates the phosphorylation of STAT33. This can be specifically identified. This mechanism is Stat1 / Stat3 double knockout. In mice, this is clearly demonstrated by a weakened IL-21 response.

[0058] IL21R signaling is important for NK cell toxicity. Human IL21R deficiency This is associated with impaired cytolysis of 51Cr-labeled K562 target cells, but is antibody-dependent. Cell damage is unaffected. Monogenic non-embryonic lethal deletion (IL21R loss-of-function mutation) This provides an excellent opportunity to clarify the innate NK cell lysis response, and therefore the innate N It is useful for modeling, enhancing, and shaping K cell lysis reactions.

[0059] CD56 dim Cell populations and CD56 bright Both cell populations have a similar number of surface ILs. Even if 21R is present, IL-21 signaling selectively targets a subset of NK cells. Forms IL-21 induction of STAT1 and STAT3 phosphorylation, CD56dimN CD56brightNK cells show higher levels compared to K cells. In contrast, IL-21 This does not affect STAT5 activation, which is an IL-2 activation pathway that also drives T cell expansion. In addition to STAT3 activation, IL-21 signaling involves the MAPK and PI3K pathways. This involves the innate immune response genes (IFN-gamma, T-bet, IL) in NK cells. It induces the expression of (including IL-12R beta-2 and IL-18R) to kill tumor cells. Priming sea urchin NK cells.

[0060] To efficiently utilize IL-21, we use mbIL-21 expression (Figure 4A) to N The trans interaction with IL21R on K cells may be concentrated and localized. Since 21 is in close proximity to the membrane, it can be readily available when needed. Optimal cell proliferation can be maintained without the need for a large and high-concentration supply of IL-21 from an external source. Co-culture with injected K562-mb15-41BBL revealed CD56+CD in peripheral blood. A median 21.6-fold expansion of 3-NK cells was induced. This expansion was due to IL-2, IL- Derived from the covalent γc family, including 12, IL-15, and IL-21 individually or in combination. This is greater than stimulation by simple soluble cytokines. In comparison, this UAPC This can enlarge NK cells by at least 1000 times (3-log) over 14-21 days. The expression of mbIL21 on UAPC does not require exogenous clinical-grade cytokines. It is possible. B.4-1BBL (4-1BB ligand, CD137 ligand, CD137L, TNF) SF9)

[0061] In addition to the idea of ​​priming NK cell function with cytokines, Direct physical interaction with activating molecules also enhances the cell proliferation response. CD137(4 -1BB) is a member of the tumor necrosis receptor (TNF-R) gene family, It mediates cell proliferation, differentiation, and programmed cell death (apoptosis). Mouse receptor After the first homolog was characterized, the human homolog was characterized, and it was found to be 6 amino acid level. They share 0% identity, and their cytoplasmic / signaling domains are significantly conserved. CD1 37 is primarily expressed in activated T cells and activated NK cells, as well as in thymocytes and myeloid cells. It is expressed at various detectable levels in cells and endothelial cells at inflammatory sites. (Physiology) Typical CD137 signaling involves 1) NF- that promotes survival through Bcl-XL activation. κB, and 2) the PI3K / ERK1 / 2 pathway which specifically drives cell cycle progression. It is mediated by.

[0062] In activated NK cells, CD137 is a cytokine-inducing co-stimulatory molecule, and this co The stimulating molecule increases cell proliferation and IFN-γ secretion, thereby affecting NK cells. This drives the antitumor response. Studies using CD137L- / - knockout mice have shown that The importance of CD137 / CD137L signaling in the development of anti-tumor immune cells has been elucidated. CD137- / - knockout mice showed a higher tumor metastasis compared to control mice. The frequency of migration was four times higher.

[0063] CD137 ligan, a 34kDa glycoprotein member of the TNF superfamily CD137L (4-1BB ligand) is primarily used in B cells, macrophages, and dendritic cells. It was detected on activated antigen-presenting cells (APCs), including T cells, and was also detected at low levels on activated T cells. It is expressed transiently. Human CD137L is only 36% homologous to its mouse counterpart. Not possible. Consistent with the antitumor efficacy of activating CD137 antibodies, the binding of CD137L is consistent with CT It has been shown to induce L and antitumor activity.

[0064] Therefore, this UAPC is a physiological counterreceptor for CD137. The 4-1BB ligand can be manipulated to express it for stimulation. C.SLAM / CD48

[0065] In addition to cytokine conditioning and 4-1BBL co-stimulation, NK cells and target Direct physical interaction with target cells also influences the cellular response, i.e., the killing of target cells. A signaling lymphocyte-activating molecule that is widely expressed in the immune system and plays a crucial role. SLAM (formerly known as the CD2 Superfamily) Family Homologousity Epidemic globulin receptors are particularly important in relation to intercellular interactions.

[0066] Therefore, the UAPCs of this disclosure may express one or more SLAM family antigens. As members of the SLAM family, CD2, CD48, CD58 (LFA-3), CD244 (2B4), CD229 (Ly9), CD319 (CS1 (CD2 subset) 1); CRACC (CD2-like receptor-activated cytotoxic cells) and CD352 (N TB-A (NK-TB antigen) is one example. In a particular embodiment, UAPC is CD NK cells express 48 and / or CS1. NK cells belong to the SLAM family (SLAMF). It expresses at least three members of the 2B4, NK cells, T cells, and B cells. Cellular antigen (NTB-A), and CD2-like receptor-activated cytotoxic cells (CRAC) C) (These are the respective ligands on target cells and possibly other NK cells.) It recognizes CD48, NTB-A and CRACC. SLAMF1, 3, 5, 6, 7, 8, and 9 are homoaffinity (self-ligand) receptors, but SLAMF2 And SLAMF4 are counterreceptors (heteroaffinity) to each other. The affinity of knowledge (dissociation constant Kd <1 μM to 200 μM) is wide. The fact is that the signal transduction mechanisms for SLAM glycoproteins are overlapping but different. This suggests the foundation of the mechanism by which things become what they are.

[0067] Table 1. Binding affinity of SLAM family members. [Table 1]

[0068] In certain embodiments, the UAPC supports intercellular interactions and enhances NK cell responses. CD48 is manipulated to express CD48. CD48 is expressed by NK cells, T cells, monocytes, etc. Glycosylphosphatidylinositol anchored tannins are found on the surface of basophils. These are proteins (GPI-APs) involved in adhesion and activation pathways in these cells. Despite lacking an intracellular domain, CD48 stimulation is effective in lipid rafts. This involves rearranging signaling factors, inducing Lck-kinase activity, and tyrosine phosphorylation. As an adhesion-costimulatory molecule, CD48 is involved in the activity of B lymphocytes and T lymphocytes, NK cells, and mass cells. It induces numerous effects in NK cells and eosinophils. In human NK cells, CD48 It is a counterreceptor for 2B426, an important activator of NK cells. Heteroaffinity interactions compete for the interaction between MHC-I and CD244. It is thought that the 2B4 / CD48 interaction is activated in human NK cells. While it induces Gnar, mouse NK cells send inhibitory signals.

[0069] 2B4-CD48 interactions between cells of the same population, i.e., interactions between NK cells, The interaction between T cells is APC (for example, K562 myeloid cells that normally lack CD48). By expressing CD48 on the (series), activation is enhanced, but this UAPC is NK This can transform the 2B4 signaling pathway in cells and turn it on. D.SLAM / CS1

[0070] In some embodiments, the UAPC switches on the killing power of NK cells. As a co-stimulatory molecule, express CS1, another member of the SLAM family. It is manipulated. Unlike CD48 which interbonds with 2B4, the CS1 interaction is homoffinity This can be characterized in a situation that contrasts cis-interactions with trans-interactions. K562 cells, which normally do not contain CS1, are manipulated to express CS1. E. Nucleic acid delivery

[0099] Certain embodiments relate to a method of treating leukemia. Leukemia is a cancer of the blood or bone marrow characterized by abnormal proliferation (production by mitotic proliferation) of blood cells, usually white blood cells (leukocytes). Leukemia is part of a broad group of diseases called blood neoplasms. Leukemia is a broad term encompassing a range of diseases. Leukemia is clinically and pathologically divided into acute and chronic forms. Acute leukemia is characterized by rapid proliferation of immature blood cells. This crowding causes the bone marrow to The body becomes unable to produce healthy blood cells. Acute leukemia occurs in children and young adults. It is possible. In acute leukemia, there is rapid progression and accumulation of malignant cells, which then flood the bloodstream. Because it can spread to other organs in the body, prompt treatment is necessary. Central nervous system (C Although involvement of NS is rare, this disease can sometimes cause cranial nerve palsy. Chronic leukemia is It is distinguished by an excessive accumulation of relatively mature but still abnormal blood cells. Over the course of several months to several years, cells are produced at a much faster rate than normal cells. This results in the production of many abnormal white blood cells in the blood. Chronic leukemia usually occurs in the elderly. Theoretically, it can occur in any age group. Acute leukemia must be treated immediately. In contrast, for chronic cases, to ensure that the effectiveness of treatment is maximized, pre-treatment is sometimes performed. You will be under surveillance for a while.

[0100] Furthermore, the above diseases are lymphocytic or lymphoblastic (normally, lymphocytes continue to form (This indicates that cancer has occurred in a certain type of bone marrow cell) and myeloid or myeloid ( A certain type of bone that normally continues to form red blood cells, several types of white blood cells, and platelets. This is classified as a condition indicating that cancer has occurred in the medullary cells.

[0101] Acute lymphoblastic leukemia (also known as acute lymphoblastic leukemia, or ALL) is It is the most common type of leukemia in young children. This disease is also common in adults, especially 6. It can develop even in people over 5 years old. Chronic lymphocytic leukemia (CLL) almost always occurs in people over 55 years old. It develops in adults. Chronic lymphocytic leukemia (CLL) occasionally occurs in younger adults. However, it rarely occurs in children. Acute myelogenous leukemia (also known as acute myeloid leukemia, or AML) usually occurs in adults rather than children. This type of leukemia was previously called acute non-lymphocytic leukemia. Chronic myelogenous leukemia (CML) mainly occurs in adults. Lymphoma is a type of cancer that originates from lymphocytes (a type of white blood cell in the immune system of vertebrates). There are many types of lymphoma. According to the National Institutes of Health, lymphoma accounts for about 5 percent of all cancer cases in the United States, and particularly Hodgkin lymphoma accounts for less than 1 percent of all cancer cases in the United States. Since the lymphatic system is part of the body's immune system, patients with a weakened immune system due to HIV infection or certain drugs or drug therapies also have a high incidence of lymphoma.

[0116] VII. Examples The following examples are included to illustrate preferred embodiments of the present invention. The disclosed methods are those that the inventors have found to work well in carrying out the present invention. Therefore, these methods can be considered to constitute a preferred form for implementation. This should be recognized by those skilled in the art. However, those skilled in the art will see this disclosure In the specific embodiments disclosed, many things can be done without departing from the spirit and scope of the present invention. It should be recognized that changes may be made, and that similar or comparable results can still be obtained.

[0117] Example 1 - Combination of mbIL21, 4-1BBL, and SLAM (CD48 / CS1) Wase Along with either CD48-Katushka or CS1-EGFP, membrane-bound I Retroviral constructs against L-21 and 41BBL (CD137 ligand) are K5 Universal antigen-presenting cells (UAPCs) were created by transduction into 62 cells. The maps and annotations of the MMLV retrovirus constructs are shown in Figures 4A-4D. NK cell sensitive K562 (HLA-A - HLA-B - ) In APC (Figure 3A) Clone 46 (Figure 3B) was generated from the forced expression of mbIL-21 and 41BBL. By forcing the expression of mbIL-1, 41BBL, and CD48 in K562 cells, U APC was produced (Figure 3C). mbIL-21, 41BBL and UAPC2 was synthesized by forcibly expressing CS1 (Figure 3D).

[0118] Numerical expansion of NK cells is achieved by activation using clone 46, UAPC, or UAPC2. The proliferation and expansion of NK cells by APC co-culture was previously achieved with clone 46. Compared to the published clone 9 (Figure 2B), the transduced NK cells (NT-NK) ) excels at expanding both CAR-transduced NK cells (SG4-NK). It showed that they were there.

[0119] The expansion of NK cells through co-culture with UAPC was previously reported as clone 9 (33 hours). Compared to the doubling time of NK cells, it has superior ability to shorten the doubling time of NK cells to 31.38 hours. This was shown to be beneficial, resulting in a growth rate of 44% in two weeks (in the case of UAPC, (1671x magnification for clone 9, compared to 1161x magnification) (Figure 2E). The relationship between the interval, magnification, and initial cell population can be simplified by the following equation:

number

[0120] In the formula, N f This is the final cell number, N b This is the initial cell, and e=2.718 28 (a mathematical constant also known as Euler's number), where T is the incubation time in units of hours. It is a range, T D This is the doubling time, measured in hours. The doubling time is the final number of cells. Because it has a numerical effect, it further enhances the proliferative advantage over the specified cell culture period. This allows for the collection of a clinically reasonable number of cells within a compressed timeframe. Therefore, this method enables the efficient production of NK cells through co-culture with UAPC.

[0121] This platform technology utilizes specific therapeutic combination pathways to advance cancer immunotherapy. The objective was to produce a large number of clinical-grade, highly functional, and cytotoxic NK cells. This provides a practical method for this purpose. The enlarged cells are 100% NK cells, and T cells are detected. Because it is impossible to obtain, unintended graft pairs are common in many immunotherapy preparations. Host side effects are avoided.

[0122] All methods disclosed and claimed herein are, in view of this disclosure, excessive. The present invention can be carried out and implemented without conducting experiments.
