Both humanized IMT001 and IMT006, derived from mouse mAbs, have high affinity for human and cynomolgus Gal3, while IMT001 also has high affinity for mouse Gal3. [Figure 51] Figure 51 depicts a graphic representation of the inhibition of TGF-β-induced procollagen production in LX-2 cells when treated with IMT001 (TB001), IMT006 (TB006; 4A11.H3L1), and hIgG4 (isotype control) at increasing concentrations of antibody. LX-2 cells were stimulated with TGF-β (10 ng / mL) for 2 hours. [Figure 52]Figure 52 depicts a graphical representation of the inhibition of TGF-β-induced procollagen production and Gal3 expression in LX-2 cells when treated with IMT001 and 4A11.H3L1. TGF-β-stimulated expression of procollagen in LX-2 cells is increased by exogenous Gal3 and inhibited by IMT006. Gal3 increased on the LX-2 cell surface (Panel A) and in the culture medium (Panel B) in response to TGF-β stimulation. The anti-Gal3 antibody IMT006 reduced procollagen protein after either TGF-β treatment or TGF-β + rhGal3. [Figure 53] Figure 53 depicts a graphical representation of reduced Gal3 and membrane TGFBR2 expression in LX2 cells transfected with a Gal3 short hairpin RNA (shRNA) vector, as well as reduced membrane TGFbR1 expression in control LX-2 cells treated with IMT001. TGFbR2 and Gal3 expression were reduced on the cell surface of LX-2 cells as a result of Gal3 knockdown. LX-2 cells were transfected with either a short hairpin RNA vector for silencing Gal3 or a control vector, and single clones were isolated (designated LX-shGal3 and LX2-shCon, respectively). After treatment with TGF-b, Gal3 expression was significantly reduced in LX2-shGal3 compared to LX2-shCon. TGFbR2 and Gal3 expression on the cell membrane of LX2-shGal3 cells was reduced compared to LX2-shCon cells. In non-transfected LX-2 cells, treatment with IMT001 reduced plasma membrane TGFbR1. [Figure 54] Figure 54 depicts a graphical representation of the inhibition of TGF-β-induced procollagen production in LX-2 cells transfected with Gal3 shRNA vectors. Knockdown of Gal3 in LX-2 cells reduces TGF-β-induced procollagen production. The TGF-β EC50 for procollagen production in the LX2-scrambled control was 1.01 ng / mL, and the TGF-β EC50 for procollagen production in the LX2-shGal3 Gal3 knockdown cells was 2.04 ng / mL. [Figure 55] Figure 55 depicts a graphical representation of the pharmacokinetics of IMT001 in rats, with a half-life of approximately 2 weeks. The PK of IMT001 is dose-proportional in rats, with a half-life of approximately 2 weeks. [Figure 56] Figure 56 depicts a graphic representation of the tissue distribution of TB006 (IMT006, 4A11.H3L1) in mice after a single injected dose. ELISA was used to measure IMT006 exposure in plasma and tissues. [Figure 57] Figure 57 depicts a graphical representation of the assay of total and unbound Gal3 in rat plasma after treatment with IMT001. A single dose of IMT001 was given via iv at 3 mg / kg (n=3) and 30 mg / kg (n=4). Samples were collected 21 days after dosing. In SD rats treated with 30 mg / kg IMT001, there was a 2.97-fold increase in total rGal3. Unbound rGal3 was approximately 85% lower than total rGal3 in SD rats treated with 30 mg / kg IMT001. Compared to untreated rats, unbound rGal3 was 55% lower after treatment with IMT001. [Figure 58] Figure 58 depicts a graphical representation of transcriptomics in methionine-choline deficient (MCD) mice treated with mIMT001 (mouse IMT001).

[0044] Detailed Description of the Disclosure Some embodiments provided herein relate to an anti-Gal3 antibody or binding fragment thereof. In some embodiments, the anti-Gal3 antibody or binding fragment thereof binds to the N-terminal domain of Gal3, the N-terminus of Gal3, or the tandem repeat domain (TRD) of Gal3.

[0045] Some embodiments provided herein relate to anti-Gal3 antibodies or binding fragments thereof that disrupt the interaction of Gal3 with proteins associated with proteopathies or neurological diseases. In some embodiments, there are methods and uses of the anti-Gal3 antibodies and binding fragments thereof disclosed herein for the treatment of proteopathies and / or neurological diseases.

[0046] Some embodiments provided herein relate to an anti-Gal3 antibody or binding fragment thereof that can cross the blood-brain barrier. In some embodiments, the blood-brain barrier is that of a subject with a neurological disease. In some embodiments, the anti-Gal3 antibody or binding fragment thereof is a multispecific antibody that increases the permeability of another antibody across the blood-brain barrier. In some embodiments, the anti-Gal3 antibody or binding fragment thereof is conjugated to a payload that increases the permeability of the payload across the blood-brain barrier.

[0047] Some embodiments provided herein relate to anti-Gal3 antibodies or binding fragments thereof that disrupt the interaction of Gal3 with cell surface markers or tumor cell surface markers. In some embodiments, there are methods and uses of the anti-Gal3 antibodies and binding fragments thereof disclosed herein for treating diseases associated with cell surface markers or tumor cell surface markers. In some embodiments, the disease is cancer, fibrosis, or an immune-related disorder.

[0048] Galectin-3 (Gal3, GAL3) plays an important role in cell proliferation, adhesion, differentiation, angiogenesis, and apoptosis. This activity is due, at least in part, to its immunomodulatory properties and binding affinity for other immunomodulatory proteins, signaling proteins, and other cell surface markers. Gal3 functions through distinct N- and C-terminal domains. The N-terminal domain (isoform 1: amino acids 1–111) contains a tandem repeat domain (TRD, isoform 1: amino acids 36–109) and is largely responsible for Gal3 oligomerization. The C-terminal domain (isoform 1: amino acids 112–250) contains a carbohydrate recognition binding domain (CRD) that binds β-galactosides.

[0049] Galectin-3 (Gal3) has been implicated in immunomodulatory activity. An example of this is the interaction of Gal3 with T-cell immunoglobulin-mucin domain-containing molecule-3 (TIM-3), which can lead to suppression of immune responses, such as T-cell activation, and allow cancer cells to escape immune clearance. This phenomenon and methods for inhibiting it are explored in U.S. Patent No. 6,223,629 (expressly incorporated herein by reference in its entirety). Anti-Gal3 antibodies and methods of use thereof are also explored, for example, in U.S. Patent No. 6,223,629 (expressly incorporated herein by reference in its entirety).

[0050] There is a long-lasting need for a deeper understanding of whether Gal3 plays a role in disease.Some diseases that may be associated with Gal3 include cancer, fibrosis, inflammatory disease, neurological disease and proteopathy, such as Alzheimer's disease.There is also a need for the development of new and improved treatments for these diseases.

[0051] Disclosed herein are various embodiments of anti-Gal3 antibodies or binding fragments thereof and methods of use, for example, for the treatment of diseases described above or otherwise provided herein.

[0052] Disclosed herein are antibodies or binding fragments thereof that bind to or are selective for Gal3, and compositions thereof. Also disclosed herein are methods for using anti-Gal3 antibodies or binding fragments thereof to disrupt the interaction of Gal3 with cell surface markers and / or proteins associated with fibrosis, liver fibrosis, kidney fibrosis, cardiac fibrosis, pulmonary fibrosis, non-alcoholic fatty liver disease, non-alcoholic steatohepatitis, sepsis, atopic dermatitis, psoriasis, cancer, brain cancer, breast cancer, colorectal cancer, kidney cancer, liver cancer, lung cancer, pancreatic cancer, bladder cancer, gastric cancer, hematological malignancies, neurodegenerative diseases, and / or proteopathies (e.g., those caused by protein misfolding or aggregation in a subject), for example, to treat diseases in a subject.

[0053] In some embodiments, the method involves an antibody that binds to Gal3 and disrupts the interaction of Gal3 with another protein. This can result in direct blockage of the interaction zone between Gal3 and the other protein, or indirect alteration, such as a conformational change in Gal3 such that Gal3 no longer binds to or is active with the other protein. It can also result from binding to the first section of Gal3, with some other portion of the antibody disrupting or altering the interaction of Gal3 with the other protein. In some embodiments, the first section of Gal3 is the N-terminal domain of Gal3, the tandem repeat domain (TRD) of Gal3, or the C-terminal domain of Gal3. In some embodiments, the antibody that binds to Gal3 does not bind to the C-terminal domain of Gal3. In some embodiments, any anti-Gal3 antibody or binding fragment thereof, or any configuration of any anti-Gal3 antibody or binding fragment provided herein, can be replaced with an antigen-binding molecule that binds to Gal3.

[0054] Alzheimer's disease (AD) is a progressive neurodegenerative disorder and the most common type of dementia. Amyloid beta (Aβ) is a major component of amyloid plaques and is therefore suspected to be a pathogenic contributor to AD. Proteolytic cleavage of the amyloid precursor protein (APP; including isoforms such as APP695) generates Aβ peptides, the aggregation of which is associated with the development of AD. Serum levels of Gal3 increase with the severity of memory loss in AD patients. Gal3 is specifically expressed in microglia, which are associated with Aβ plaques. Gal3 expression is also significantly increased in the frontal cortex of AD patients, in parallel with enhanced Aβ oligomerization. O-glycosylation can occur at Tyr-10 of Aβ peptides in human cerebrospinal fluid and is increased in AD patients.

[0055] Disclosed herein are antibodies specific for Gal3 and binding fragments thereof, and methods of using them for the treatment or prevention of neurodegenerative diseases and / or proteopathies (e.g., Alzheimer's disease). The anti-Gal3 antibodies and binding fragments thereof disclosed herein disrupt the interaction of Gal3 with proteins associated with neurodegenerative diseases and / or proteopathies. In some embodiments, the proteins associated with neurodegenerative diseases and / or proteopathies cause disease in subjects due to protein misfolding or aggregation. One non-limiting example of a protein associated with neurodegenerative diseases and / or proteopathies is amyloid-beta (Aβ) peptide.

[0056] In some embodiments, the anti-Gal3 antibodies or binding fragments disclosed herein disrupt the interaction of Gal3 with APP695. Some exemplary antibodies that strongly (e.g., at least 90%) disrupt the interaction of Gal3 with APP695 include 19B5.2E6, 7D8.2D8, F846C.1B2, F846C.1H12, F846TC.14A2, F849C.8D10, F849C.8H3, 4A11.H3L1 [IMT006-5 (TB006)], 15F Some exemplary antibodies that moderately (e.g., at least 45%) disrupt the interaction of Gal3 with APP695 include, but are not limited to, 10.2D6, F846TC.16B5, 23H9.2E4, F846C.1F5, IMT001-4[TB001], F846C.2H3, 14H10.2C9, 15FG7.2A7, 20H5.A3, F846TC.14E4, 3B11.2G2, 20D11.2C6, and 2D10.2B2. Some exemplary antibodies that moderately (e.g., at least 45%) disrupt the interaction of Gal3 with APP695 include, but are not limited to, 13G4.2F8, F846TC.7F10, F847C.12F12, and F847C.4B10. In some embodiments, any anti-Gal3 antibody or binding fragment thereof, or any configuration of any anti-Gal3 antibody or binding fragment provided herein, may be replaced with an antigen-binding molecule that binds to Gal3.

[0057] In some embodiments, the anti-Gal3 antibodies or binding fragments disclosed herein disrupt the interaction of Gal3 with Aβ (e.g., Aβ monomers, oligomers, or fibrils, or any combination thereof). Some exemplary antibodies that strongly (e.g., at least 90%) disrupt the interaction of Gal3 with Aβ monomers include, but are not limited to, 2D10.2B2, 20D11.2C6, 3B11.2G2, 20H5.A3, 846TC.14E4, 15G7.2A7, 14H10.2C9, 846C.2H3, TB001, 846C.1F5, 846TC.16B5, TB006, 846C.1B2, 846TC.14A2, 849C.8D10, and 19B5.2E6. Some exemplary antibodies that strongly (e.g., at least 90%) disrupt the interaction between Gal3 and Aβ oligomers include, but are not limited to, 2D10.2B2, 20D11.2C6, 3B11.2G2, 20H5.A3, 846TC.14E4, 14H10.2C9, TB001, 846C.1F5, and TB006. In some embodiments, the anti-Gal3 antibodies or binding fragments disclosed herein block the interaction between Gal3 and Aβ oligomers better than the small molecule Gal3 inhibitor TD139. In some embodiments, any of the anti-Gal3 antibodies or binding fragments thereof, or any configuration of any of the anti-Gal3 antibodies or binding fragments provided herein, may be replaced with an antigen-binding molecule that binds to Gal3.

[0058] In some embodiments, administering any one of the anti-Gal3 antibodies or binding fragments disclosed herein can at least one of, if not both, enhance cognitive function and / or attenuate the accumulation of toxic conformational species of Aβ, e.g., Aβ oligomers and / or Aβ fibrils, in a subject.

[0059] In some embodiments, administering any one of the anti-Gal3 antibodies or binding fragments disclosed herein can reduce inflammation (e.g., inflammation of the brain) and / or encephalitis in a subject.

[0060] In some embodiments, administering any one of the anti-Gal3 antibodies or binding fragments disclosed herein can do one or more of the following in the brain of a subject: reduce phospho-tau levels, reduce microglial activation (as detected by an Iba-1 antibody), or reduce Gal3 levels.

[0061] In some embodiments, administering any one of the anti-Gal3 antibodies or binding fragments disclosed herein can at least one of regenerating neuronal structures and / or reducing extracellular Aβ in a subject, if not both.

[0062] In some embodiments, administering any one of the anti-Gal3 antibodies or binding fragments disclosed herein can promote microglial phagocytic function and promote clearance of Aβ deposits in a subject.

[0063] In some embodiments, administering any one of the anti-Gal3 antibodies or binding fragments disclosed herein can inhibit Aβ aggregate (e.g., Aβ oligomers or Aβ fibrils)-mediated activation of microglia in a subject.

[0064] In some embodiments, administering any one of the anti-Gal3 antibodies or binding fragments disclosed herein can block the interaction of Gal3 with TLR4 or TREM2, or both.

[0065] Also provided herein are embodiments relating to anti-Gal3 antibodies or binding fragments and their use in methods of disrupting the interaction of Gal3 with cell surface markers, such as TGF-β, VEGFR1, VEGFR2, VEGFR3, EGFR, PDGFRa, PDGFRb, ErbB2, HGFR, TNF-sRI, CTLA4, CD47, PD-L1, FGFR, FGFR1 alpha-IIIb, FGFR1 alpha-IIIc, FGFR IIIc, or FGFR4. In some embodiments, this disruption can be used to alter biological processes regulated by these cell surface markers. In some embodiments, the cell surface marker is a tumor cell surface marker, a cancer cell surface marker, or a fibrocyte surface marker.

[0066] Cells use a wide range of signaling molecules and cognate cell surface receptors for signal transduction and cell communication. Abnormal function of these interactions has been linked to many diseases and disorders. For example, TGF-β is a potent signaling molecule that acts with pleiotropic effects, including modulation of immune processes during the progression of cancer or fibrosis, such as liver fibrosis.

[0067] For example, biological processes regulated by TGF-β include (but are not limited to): a) TGF-β regulates many biological responses, including tissue fibrosis (liver, kidney, lung, heart, etc.), cell proliferation, apoptosis, differentiation, autophagy, and immune responses; b) TGF-β plays an essential role in liver physiology and pathology, contributing to all stages of disease progression, from liver injury to inflammation, fibrosis, cirrhosis, and hepatocellular carcinoma; c) TGF-β also mediates the epithelial-mesenchymal transition process in hepatocytes, which can directly or indirectly contribute to an increase in the myofibroblast (MFB) population; hepatic stellate cell (HSC) activation is one of the most important steps during liver fibrosis; and d) TGF-β plays an essential role in the activation of HSCs into MFBs, which are the major cause of extracellular matrix protein accumulation and prominent mediators of fibrosis. Therefore, in some embodiments, any one or more of the above processes can be disrupted through the use of Gal3 antibodies that reduce binding of Gal3 to the TGF-β receptor.

[0068] TGF-β binds to the TGF-βRII receptor, which binds to and phosphorylates TGF-βRI, triggering the recruitment of receptor-regulated SMAD proteins (R-SMADs) SMAD2 and SMAD3 to the cytoplasmic domain of activated TGF-βRI, which then phosphorylates SMAD2 / 3. Upon phosphorylation, SMAD2 / 3 form a trimer with SMAD4, which then translocates to the nucleus, where it binds to SMAD-binding elements and modulates gene expression. In some embodiments, the antibodies or binding fragments provided herein alter the binding of TGF-β to TGF-βRII by altering the manner in which TGF-β binds to its receptor. In some embodiments, the antibodies or binding fragments do not alter the binding of TGF-β to TGF-βRII by altering the manner in which TGF-β binds to Gal3.

[0069] TGF-β activates a number of SMAD-independent signaling pathways, referred to as non-canonical TGF-β pathways, such as the WNT, ERK, P38, MAPK, PI3K, and AKT pathways. In some embodiments, the antibodies or binding fragments provided herein can alter the manner in which TGF-β binds to its receptor, thereby altering the manner in which TGF-β activates these multiple SMAD-independent signaling pathways.

[0070] Inflammation plays a key role in the development of liver fibrosis. After injury, infiltrating immune cells (macrophages, lymphocytes, eosinophils, and plasma cells) are recruited to the damaged site. Lymphocytes produce secreted protein signaling molecules called cytokines and chemokines, which activate macrophages. Activated macrophages then stimulate inflammatory cells, such as lymphocytes, among others, contributing to the sustained maintenance of a pro-inflammatory environment. During fibrosis, macrophages produce pro-fibrotic factors, such as TGF-β and platelet-derived growth factor (PDGF), and control extracellular matrix turnover by regulating the balance of various matrix metalloproteinases (MMPs) and tissue inhibitors of metalloproteinases (TIMPs). Macrophages are found in close proximity to collagen-producing myofibroblasts, suggesting that macrophages are highly involved in the activation of MFBs. In this context, hepatic macrophages have been described as a potential target for the treatment of liver fibrosis. In vitro and in vivo studies have demonstrated that both Kupffer cells and monocyte-derived macrophages can activate HSCs and induce their transdifferentiation through paracrine mechanisms, including through TGF-β. Endogenous liver macrophages secrete the chemokine CCL2 (a potent chemoattractant) to recruit monocytes, which can increase and promote fibrosis. Macrophages are essential players in the regulation of liver fibrosis and are an important source of TGF-β. Recent observations point to a role for TGF-β in inducing profibrotic M2-like macrophage localization via SNAIL. M2 activation / localization plays a relevant role in the development of fibrosis in mice and patients with liver fibrosis. Therefore, in some embodiments, the role of TGF-β is altered by applying one or more of the anti-Gal3 antibodies or binding fragments thereof provided herein that disrupt the interaction of Gal3 with the TGF-β receptor, thereby altering one or more of the above pathways or processes.

[0071] In some embodiments, the method involves an antibody or binding fragment thereof that binds to Gal3 and disrupts the interaction of Gal3 with a cell surface marker or cell surface receptor. In some embodiments, the cell surface marker or cell surface receptor is a cell surface marker or cell surface receptor that appears on tumor cells, immune cells, cancer cells, or fibrocytes. This can result in direct blockage of the interaction zone between Gal3 and the cell surface marker or cell surface receptor, or indirect alteration, such as a conformational change in Gal3 such that Gal3 is no longer able to bind to or be active with the cell surface marker or cell surface receptor. It can also result from binding to the first section of Gal3 while some other portion of the antibody disrupts or alters the interaction of Gal3 with the cell surface marker or cell surface receptor.

[0072] In some embodiments, the methods involve antibodies that bind to Gal3 and disrupt the interaction of Gal3 with TGF-beta receptor, VEGFR1, VEGFR2, VEGFR3, EGFR, PDGFRa, PDGFRb, ErbB2, HGFR, TNF sRI, CTLA4, CD47, PD-L1, FGFR1 alpha-IIIb, FGFR1 alpha-IIIc, FGFR2 alpha-IIIc, FGFR3 IIIc, or FGFR4, or any combination thereof. This can result in a direct blockage of the interaction zone between Gal3 and TGF-β receptor, VEGFR1, VEGFR2, VEGFR3, EGFR, PDGFRa, PDGFRb, ErbB2, HGFR, TNF-sRI, CTLA4, CD47, PD-L1, FGFR1 alpha-IIIb, FGFR1 alpha-IIIc, FGFR2 alpha-IIIc, FGFR3 IIIc, or FGFR4, or any combination thereof; or indirect alteration, e.g., a conformational change of Gal3, such that Gal3 no longer interacts with TGF-β receptor, VEGFR1, VEGFR2, VEGFR3, EGFR, PDGFRa, PDGFRb, ErbB2, HGFR, TNF-sRI, CTLA4, CD47, PD-L1, FGFR1 alpha-IIIb, FGFR1 alpha-IIIc, FGFR2 alpha-IIIc, FGFR3 IIIc, or FGFR4, or any combination thereof. The binding can be such that the antibody no longer binds to or is active with TGF-β receptor, VEGFR1, VEGFR2, VEGFR3, EGFR, PDGFRa, PDGFRb, ErbB2, HGFR, TNF sRI, CTLA4, CD47, PD-L1, FGFR1 alpha-IIIb, FGFR1 alpha-IIIc, FGFR2 alpha-IIIc, FGFR3 IIIc, or FGFR4, or any combination thereof. It can also be the result of binding to the first section of Gal3 while some other portion of the antibody interferes with or alters the interaction of Gal3 with TGF-β receptor, VEGFR1, VEGFR2, VEGFR3, EGFR, PDGFRa, PDGFRb, ErbB2, HGFR, TNF sRI, CTLA4, CD47, PD-L1, FGFR1 alpha-IIIb, FGFR1 alpha-IIIc, FGFR2 alpha-IIIc, FGFR3 IIIc, or FGFR4, or any combination thereof.

[0073] In some embodiments, any anti-Gal3 antibody or binding fragment thereof, or any configuration of any anti-Gal3 antibody or binding fragment provided herein, may be replaced with an antigen-binding molecule that binds to Gal3. Thus, although the present disclosure also contemplates antigen-binding molecules whenever it refers to an antibody or binding fragment thereof, for brevity, the present disclosure may simply refer to an antibody or binding fragment thereof. It is noted that the term "antigen-binding molecule" encompasses antibodies and binding fragments thereof and represents a broader genus of options.

[0074] This disclosure claims priority to one or more priority documents, which may be submitted with one or more appendices. All subject matter disclosed in the priority documents and any appendices is hereby expressly contemplated as part of the disclosure in this document as further embodiments that can be combined and / or modified with any of the embodiments provided herein. All subject matter disclosed in the priority documents and appendices, including but not limited to antibodies, binding fragments thereof, antigen-binding molecules, and any methods, such as methods of manufacture, use, or treatment, may be applied to any of the embodiments or configurations disclosed in this section of the application. Similarly, all subject matter disclosed herein, including but not limited to antibodies, binding fragments thereof, antigen-binding molecules, and any methods, such as methods of manufacture, use, or treatment, is contemplated as being applied to any of the embodiments or configurations disclosed in the priority documents and appendices.

[0075] definition In the following detailed description, reference is made to the accompanying drawings, which form a part hereof. In the drawings, like symbols typically identify like components, unless context dictates otherwise. The illustrative embodiments described in the detailed description, drawings, and claims are not meant to be limiting. Other embodiments may be utilized, and other changes may be made, without departing from the spirit or scope of the subject matter presented herein. It will be readily understood that the aspects of the present disclosure, as generally described herein and illustrated in the drawings, can be adapted, substituted, combined, separated, and designed in a variety of different configurations, all of which are expressly contemplated herein.

[0076] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the claimed subject matter belongs. It is to be understood that the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of any claimed subject matter.

[0077] The section headings used herein are for organizational purposes only and should not be construed as limiting the subject matter described.

[0078] The articles "a" and "an" are used herein to refer to one or to more than one (e.g., to at least one) of the grammatical object of the article. By way of example, "an element" means one element or more than one element.

[0079] By "about" is meant an amount, level, value, number, frequency, percentage, dimension, size, amount, weight or length that varies by up to about 30, 25, 20, 15, 10, 9, 8, 7, 6, 5, 4, 3, 2, or 1% of the referenced quantity, level, value, number, frequency, percentage, dimension, size, amount, weight or length.

[0080] Throughout this specification, unless the context requires otherwise, the words "comprise," "comprises," and "comprising" are understood to imply the inclusion of a recited step or element or group of steps or elements, but not the exclusion of any other step or element or group of steps or elements. By "consisting of," it is meant to include and be limited to whatever precedes the phrase "consisting of." Thus, the phrase "consisting of" indicates that the listed elements are required or mandatory, and that no other elements may be present. By "consisting essentially of," it is meant to include any elements listed before it, and to be limited to other elements that do not interfere with or contribute to the activity or function specified in this disclosure for the listed elements. Thus, the phrase "consisting essentially of" indicates that the listed elements are required or mandatory, but that other elements are optional and may or may not be present depending on whether they substantially affect the activity or function of the listed elements.

[0081] As used herein, the terms "individual," "subject," and "patient" refer to any mammal. In some embodiments, the mammal is a human. In some embodiments, the mammal is a non-human. None of the terms require or are limited to situations characterized by the supervision (e.g., constant or intermittent) of a medical professional (e.g., a physician, registered nurse, nurse practitioner, physician assistant, orderly, or hospice worker).

[0082] The terms "polypeptide", "peptide" and "protein" are used interchangeably herein to refer to any length of amino acid polymer.Polymer may be linear, cyclic or branched, may contain modified amino acids, and may be interspersed with non-amino acids.The term also encompasses modified amino acid polymers, for example, through sulfation, glycosylation, lipidation, acetylation, phosphorylation, iodination, methylation, oxidation, proteolytic processing, phosphorylation, prenylation, racemization, selenoylation, transfer RNA-mediated addition of amino acids to proteins, for example, arginylation, ubiquitination, or any other manipulation, for example, conjugation with a labeling component.

[0083] As used herein, the term "amino acid" refers to either natural and / or unnatural or synthetic amino acids, including glycine and both the D or L optical isomers, as well as amino acid analogs and peptidomimetics.

[0084] A polypeptide or amino acid sequence "derived from" a specified protein refers to the origin of the polypeptide. Preferably, the polypeptide has an amino acid sequence essentially identical to the amino acid sequence of the polypeptide encoded in the sequence, or a portion thereof, comprising at least 10-20 amino acids, or at least 20-30 amino acids, or at least 30-50 amino acids, or an amino acid sequence immunologically identifiable from the polypeptide encoded in the sequence. The term also includes polypeptides expressed from a specified nucleic acid sequence. Peptide sequences having at least 80%, 85%, 90%, 95%, 99%, or 100% homology to any one of the peptide sequences disclosed herein and having the same or similar functional properties are contemplated. The percent homology may be determined according to amino acid substitutions, deletions, or additions between the two peptide sequences. Peptide sequences having any percent homology to any one of the peptide sequences disclosed herein can be prepared and tested by one of skill in the art through conventional methods.

[0085] As used herein, the term "antibody" refers to the meaning ascribed to it by those skilled in the art and is further intended to include any polypeptide chain-containing molecular structure having a unique shape that fits and recognizes an epitope, with one or more non-covalent interactions stabilizing the complex between the molecular structure and the epitope. While the antibodies utilized in the present invention may be polyclonal, monoclonal antibodies are preferred because they can be reproduced in cell culture or recombinantly and can be modified to reduce their antigenicity.

[0086] In addition to whole immunoglobulins (or their recombinant counterparts), immunoglobulin fragments or "binding fragments" containing epitope-binding sites (e.g., Fab', F(ab')2, single-chain variable fragments (scFv), diabodies, minibodies, nanobodies, single-domain antibodies (sdAb), or other fragments) are useful as antibody portions in the present invention. Such antibody fragments can be generated from whole immunoglobulins by ricin, pepsin, papain, or other protease cleavage. Minimal immunoglobulins can be engineered using recombinant immunoglobulin technology. For example, "Fv" immunoglobulins for use in the present invention can be produced by linking the variable light chain region to the variable heavy chain region via a peptide linker (e.g., poly-glycine or another sequence that does not form an alpha-helix or beta-sheet motif). Nanobodies or single-domain antibodies can also be derived from selected organisms, such as dromedaries, camels, llamas, alpacas, or sharks. In some embodiments, the antibody can be a conjugate, such as a pegylated antibody, a drug, a radioisotope, or a toxin conjugate. Monoclonal antibodies directed to a specific epitope or a combination of epitopes can target and / or deplete cell populations that express markers. A variety of techniques using monoclonal antibodies to screen cell populations that express markers are available, including magnetic separation using antibody-coated magnetic beads, "panning" using antibodies attached to a solid matrix (i.e., plate), and flow cytometry (see, e.g., Patent Document 3; expressly incorporated herein by reference in its entirety).

[0087] As known in the art, the term "Fc region" is used to define the C-terminal region of an immunoglobulin heavy chain. The "Fc region" may be a native sequence Fc region or a variant Fc region. Although the boundaries of the Fc region of an immunoglobulin heavy chain can vary, the human IgG heavy chain Fc region is usually defined to stretch from the amino acid residue at position Cys226, or from Pro230, to the carboxyl terminus. The numbering of residues in the Fc region is that of the EU index as in Kabat. (Non-Patent Document 1). The Fc region of an immunoglobulin generally comprises two constant domains, CH2 and CH3. As known in the art, the Fc region can exist in a dimeric or monomeric form.

[0088] As known in the art, a "constant region" of an antibody refers to the constant region of the antibody light chain or the constant region of the antibody heavy chain, either alone or in combination.

[0089] The "variable region" of an antibody refers to the variable region of the antibody light chain or the variable region of the antibody heavy chain, either alone or in combination. As is known in the art, each of the heavy and light chain variable regions consists of four framework regions (FRs) connected by three complementarity-determining regions (CDRs), also known as hypervariable regions, which contribute to the formation of the antigen-binding site of the antibody. When a variant of a subject variable region is desired, particularly one having a substitution of an amino acid residue outside the CDR region (i.e., in the framework region), appropriate amino acid substitutions, preferably conservative amino acid substitutions, can be identified by comparing the subject variable region with the variable regions of other antibodies containing CDR1 and CDR2 sequences in the same canonical class as the subject variable region (Non-Patent Document 2).

[0090] In certain embodiments, definitive delineation of CDRs and identification of the residues that constitute the antibody binding site are achieved by solving the structure of the antibody and / or the structure of the antibody-ligand complex. In certain embodiments, this can be achieved by any of a variety of techniques known to those skilled in the art, such as X-ray crystallography. In certain embodiments, various analytical methods can be used to identify or estimate CDR regions. In certain embodiments, various analytical methods can be used to identify or estimate CDR regions. Examples of such methods include, but are not limited to, the Kabat definition, the Chothia definition, the IMGT approach (Non-Patent Document 3), computer programs such as Paratome (Non-Patent Document 4), the AbM definition, and conformational definitions.

[0091] The Kabat definition is a standard for numbering residues in antibodies and is typically used to identify CDR regions. See, e.g., Non-Patent Document 5. The Chothia definition is similar to the Kabat definition, but takes into account the location of certain structural loop regions. See, e.g., Non-Patent Document 6; Non-Patent Document 7. The AbM definition uses an integrated computer program produced by the Oxford Molecular Group to model antibody structure. See, e.g., Non-Patent Document 8; Non-Patent Document 9. The AbM definition models the tertiary structure of an antibody from its primary sequence using a combination of knowledge databases and ab initio methods, such as those described in Non-Patent Document 10. The contact definition is based on an analysis of available complex crystal structures. See, e.g., Non-Patent Document 11. In another approach, referred to herein as the "conformational definition" of CDRs, the positions of CDRs can be identified as residues that contribute enthalpic-wise to antigen binding. See, e.g., Non-Patent Document 12. Still other CDR boundary definitions may not strictly follow one of the above approaches, but nevertheless overlap with at least a portion of the Kabat CDRs, although they may be shortened or extended in light of predicted or experimental findings that certain residues or groups of residues do not significantly affect antigen binding. As used herein, CDRs can refer to CDRs defined by any approach known in the art, including combinations of approaches. The methods used herein may utilize CDRs defined according to any of these approaches. For any given embodiment containing more than one CDR, the CDRs may be defined according to any of the Kabat, Chothia, extended, IMGT, Paratome, AbM, and / or conformational definitions, or any combination thereof.

[0092] The term "compete," as used herein with respect to antibodies, means that a first antibody, or antigen-binding portion thereof, binds to an epitope in a manner sufficiently similar to that of a second antibody, or antigen-binding portion thereof, such that the binding of the first antibody to its cognate epitope is detectably reduced in the presence of the second antibody compared to the binding of the first antibody in the absence of the second antibody. Binding of the second antibody to its epitope can optionally also be detectably reduced in the presence of the first antibody, but this need not be the case. That is, a first antibody can inhibit binding of a second antibody to its epitope without the second antibody inhibiting binding of the first antibody to its respective epitope. However, antibodies are said to "cross-compete" with each other for binding of their respective epitopes if each antibody detectably inhibits binding of the other antibody to its cognate epitope or ligand, whether to the same, greater, or lesser extent. Both competing and cross-competing antibodies are encompassed by the present invention. Regardless of the mechanism by which such competition or cross-competition occurs (e.g., steric hindrance, conformational change, or binding to a common epitope, or portion thereof), those skilled in the art will recognize that, based on the teachings provided herein, such competing and / or cross-competing antibodies are encompassed and may be useful for the methods disclosed herein.

[0093] An antibody that "preferentially binds" or "specifically binds" (used interchangeably herein) to an epitope is a term well understood in the art, and methods for determining such specific or preferential binding are also well known in the art. A molecule is said to exhibit "specific binding" or "preferential binding" if it reacts or associates more frequently, and / or more rapidly, and / or with a longer duration, and / or with a higher affinity with a particular cell or substance than with alternative cells or substances. An antibody "specifically binds" or "preferentially binds" to a target if it binds with higher affinity and / or avidity and / or more readily and / or with a longer duration than it binds to other substances. For example, an antibody that specifically or preferentially binds to a CFD epitope is an antibody that binds to this epitope with higher affinity and / or avidity, and / or more readily and / or with a longer duration than it binds to other CFD epitopes or non-CFD epitopes. For example, it is understood by reading this definition that an antibody (or portion or epitope) that specifically or preferentially binds to a first target may or may not also specifically or preferentially bind to a second target. Thus, "specific binding" or "preferential binding" does not necessarily require (although can include) exclusive binding. Generally, but not necessarily, reference to binding means preferential binding.

[0094] As used herein, the term "antigen-binding molecule" refers to a molecule comprising an antigen-binding portion that binds to an antigen and, optionally, a scaffold or framework portion that allows the antigen-binding portion to adopt a conformation that facilitates binding of the antigen-binding portion or provides some additional property to the antigen-binding molecule. In some embodiments, the antigen is Gal3. In some embodiments, the antigen-binding portion comprises at least one CDR from an antibody that binds to the antigen. In some embodiments, the antigen-binding portion comprises all three CDRs from the heavy chain of the antibody that binds the antigen or from the light chain of the antibody that binds the antigen. In some embodiments, the antigen-binding portion comprises all six CDRs (three from the heavy chain and three from the light chain) from an antibody that binds the antigen. In some embodiments, the antigen-binding portion is an antibody fragment.

[0095] Non-limiting examples of antigen-binding molecules include antibodies, antibody fragments (e.g., antigen-binding fragments of antibodies), antibody derivatives, and antibody analogs. Further specific examples include, but are not limited to, single-chain variable fragments (scFv), nanobodies (e.g., VH domains of camelid heavy chain antibodies; VHH fragments, see Non-Patent Document 13), Fab fragments, Fab' fragments, F(ab')2 fragments, Fv fragments, Fd fragments, and complementarity-determining region (CDR) fragments. These molecules can be derived from any mammalian source, such as human, mouse, rat, rabbit, pig, dog, cat, horse, donkey, guinea pig, goat, or camelid. Antibody fragments may compete with intact antibodies for target antigen binding, and fragments may be produced by modification of intact antibodies (e.g., enzymatic or chemical cleavage) or synthesized de novo using recombinant DNA technology or peptide synthesis. Antigen-binding molecules can include, for example, alternative protein scaffolds or artificial scaffolds with grafted CDRs or CDR derivatives. Such scaffolds include, but are not limited to, antibody-derived scaffolds containing mutations introduced to stabilize the three-dimensional structure of the antigen-binding molecule, as well as entirely synthetic scaffolds, for example, including biocompatible polymers. See, for example, Non-Patent Document 14; Non-Patent Document 15. Additionally, in addition to peptide antibody mimics ("PAMs"), scaffolds based on antibody mimics that utilize fibronectin components as scaffolds can be used.

[0096] An antigen-binding molecule can also include proteins containing one or more antibody fragments incorporated into a single polypeptide chain or multiple polypeptide chains. For example, antigen-binding molecules may include, but are not limited to, diabodies (see, e.g., Patent Document 4; Patent Document 5; and Non-Patent Document 16); intrabodies; domain antibodies (a single VL or VH domain, or two or more VH domains joined by a peptide linker; see Non-Patent Document 17); maxibodies (two scFvs fused to an Fc region; see Non-Patent Document 18 and Non-Patent Document 19); triabodies; tetrabodies; minibodies (scFvs fused to a CH3 domain; see Non-Patent Document 20); peptibodies (one or more peptides attached to an Fc region; see Patent Document 6); linear antibodies (a pair of tandem Fd segments (VH-CH1-VH-CH1); see Non-Patent Document 21), which form a pair of antigen-binding regions together with complementary light chain polypeptides; small modular immunopharmaceuticals (see Patent Document 7); and immunoglobulin fusion proteins (e.g., IgG-scFv, IgG-Fab, 2scFv-IgG, 4scFv-IgG, VH-IgG, IgG-VH, and Fab-scFv-Fc).

[0097] In certain embodiments, the antigen-binding molecule can have the structure of, for example, an immunoglobulin. An "immunoglobulin" is a tetrameric molecule, with each tetramer containing two identical pairs of polypeptide chains, each pair having one "light" chain (approximately 25 kDa) and one "heavy" chain (approximately 50-70 kDa). The amino-terminal portion of each chain contains a variable region of approximately 100-110 or more amino acids primarily responsible for antigen recognition. The carboxy-terminal portion of each chain defines a constant region primarily responsible for effector function.

[0098] As used herein, the terms "treat" or "treatment" (as understood in the art) refer to an approach to obtain beneficial or desired results in a subject's condition, including clinical results. Beneficial or desired clinical results can include, but are not limited to, the alleviation or amelioration of one or more symptoms or conditions, whether partial or total, and whether detectable or undetectable; a reduction in the extent of the disease; stabilization (i.e., not worsening) of the disease state; prevention of the spread or spread of the disease; delay or slowing of disease progression; remission or palliation of the disease state; reduction in disease recurrence; and remission. "Treat" and "treatment," as used herein, also include prophylactic treatment. Treatment methods include administering a therapeutically effective amount of an active agent to a subject. The administering step may consist of a single administration or may include a series of administrations. The composition is administered to the subject in an amount and for a duration sufficient to treat the subject. The length of the treatment period depends on various factors, such as the severity of the condition, the age and genetic profile of the subject, the concentration of the active agent, the activity of the composition used in the treatment, or a combination thereof. It is also recognized that the effective dosage of an agent used for treatment or prevention may increase or decrease over the course of a particular treatment or prevention regime. Changes in dosage may be determined and revealed by standard diagnostic assays known in the art. In some cases, chronic administration may be required.

[0099] The term "effective amount" or "effective dose" as used herein has its plain and ordinary meaning as understood in light of the present specification, and refers to the amount of the described composition or compound that results in an observable, specified effect. The actual dosage level of the active ingredient in the active composition of the presently disclosed subject matter can be modified to administer an amount of the active composition or compound that is effective to achieve the specified response for a specific subject and / or application. The selected dosage level can be modified based on various factors, including, but not limited to, the activity of the composition, formulation, route of administration, combination with other drugs or treatments, the severity of the condition being treated, and the physical condition and past medical history of the subject being treated. In some embodiments, a minimum dose is administered, and the dose is titrated up in the absence of dose-limiting toxicity to the minimum effective dose. In addition to determining and adjusting the effective dose, evaluation of the timing and method of making such adjustments is contemplated herein.

[0100] The term "administering" includes oral administration, topical contact, administration as a suppository, intravenous, intraperitoneal, intramuscular, intralesional, intrathecal, intranasal, or subcutaneous administration to a subject, or implantation of a slow-release device, such as a mini-osmotic pump. Administration can be by any route, including parenteral and transmucosal (e.g., buccal, sublingual, palatal, gingival, nasal, vaginal, rectal, or transdermal). Parenteral administration can include, for example, intravenous, intramuscular, intraarterial, intradermal, subcutaneous, intraperitoneal, intraventricular, and intracranial. Other modes of delivery include, but are not limited to, the use of liposomal formulations, intravenous infusion, transdermal patches, and the like. By "co-administering" is meant that a first compound described herein is administered simultaneously with, immediately before, or immediately after the administration of a second compound described herein.

[0101] As used herein, the term "therapeutic target" refers to a gene or gene product, the modulation of whose activity (e.g., by expression, modulation of biological activity, etc.) can provide for modulation of a disease phenotype. As used throughout, "modulation" is meant to refer to an increase or decrease in the indicated phenomenon (e.g., modulation of biological activity refers to an increase in biological activity or a decrease in biological activity).

[0102] As used herein, the terms "standard of care," "best practice," and "standard therapy" refer to treatments that are accepted by physicians as appropriate, reasonable, effective, and / or widely used for a particular disease. The standard of care for a particular disease depends on many different factors, including the biological effectiveness of the treatment, the area or location in the body, the condition of the patient (e.g., age, weight, sex, genetic risks, other disabilities, secondary conditions), toxicity, metabolism, bioaccumulation, therapeutic index, dosage, and other factors known in the art. Determining the standard of care for a disease also depends on establishing safety and efficacy in clinical trials standardized by regulatory agencies, such as the US Food and Drug Administration, the International Council for Harmonization of Technical Requirements for Registration of Pharmaceuticals for Human Use, Health Canada, the European Medicines Agency, the Therapeutics Goods Administration, the Central Drugs Standard Control Organization of India, the National Medical Products Administration of China, the Pharmaceuticals and Medical Devices Agency, the Ministry of Food and Drug Safety, and the World Health Organization. Standard treatments for a disease may include, but are not limited to, surgery, radiation, chemotherapy, targeted therapy, or immunotherapy (e.g., PD1 / PDL1 or CTLA4 blockade). For example, temozolomide is an orally administered chemotherapy compound used as a standard of care treatment for brain cancers, such as glioblastoma and astrocytoma.Those skilled in the art will recognize that the ability of temozolomide to cross the blood-brain barrier is one aspect that determines its usefulness as a standard of care for these diseases, and that temozolomide may not necessarily be used as a standard of care treatment for other diseases.

[0103] As used herein, the term "supplement" refers to a compound, molecule, or substance that provides an effect to patients and is provided in combination with at least one other compound, molecule, or substance for treating cancer.The term "immuno-oncology supplement" refers to a supplement that provides an effect to the patient's immune system.The administration of at least two compounds, molecules, or substances can also be referred to as combination therapy.In some embodiments, at least one other compound, molecule, or substance is PD1 blockade therapy, PDL1 blockade therapy, or CTLA4 blockade therapy.

[0104] As used herein, "PD1 blockade therapy" refers to a PD1 inhibitor treatment that involves blocking the interaction between programmed cell death protein 1 (PD1) and programmed cell death ligand 1 (PDL1). Cancer cells express PDL1, and PDL1 binds to PD1 expressed on T cells or other immune cells to inhibit immune clearance of cancer cells. PD1 inhibitors block this interaction by binding to or inhibiting PD1. PD1 inhibitors include, but are not limited to, pembrolizumab, nivolumab, cemiplimab, spartalizumab, camrelizumab, sintilimab, tislelizumab, toripalimab, AMP-224, or AMP-514, or any combination thereof. As used herein, "PDL1 blockade therapy" refers to a PDL1 inhibitor treatment that behaves similarly to a PD1 inhibitor. PDL1 inhibitors bind to or inhibit PDL1. PDL1 inhibitors include, but are not limited to, atezolizumab, avelumab, durvalumab, KN035, CK-301, AUNP12, CA-170, or BMS-986189, or any combination thereof.

As used herein, "CTLA4 blockade therapy" refers to CTLA4 inhibitor therapy involving blocking the interaction of cytotoxic T-lymphocyte-associated protein 4 (CTLA4) with CD80 or CD86. T cells express CTLA4, which binds to CD80 or CD86 on other T cells to inhibit their immune activity. CTLA4 inhibitors include, but are not limited to, ipilimumab or tremelimumab. PD1 blockade therapy, PDL1 blockade therapy, and / or CTLA4 blockade therapy are used as standard treatments for some cancers or other diseases.

[0105] As used herein, the term "neurological disorder" refers to a disease that affects the central and / or peripheral nervous system of a patient.Neurological disorders have physical causes, such as external or internal mechanical trauma (for example, stroke or concussion), biological trauma (for example, infection), chemical trauma (for example, toxins or drugs), aging and age-related aging, genetics, and many other causes.Some neurological disorders are caused by the effects or accumulation of mutations or misfolded proteins.These diseases may involve the death of neurons or other cell types associated with the nervous system. Non-limiting examples of neurological disorders include inflammation, encephalitis, Alzheimer's disease, Parkinson's disease, Huntington's disease, traumatic brain injury, spinal cord injury, multiple sclerosis, amyotrophic lateral sclerosis, olfactory dysfunction, aphasia, Bell's palsy, transmissible spongiform encephalopathy, Creutzfeldt-Jakob disease, fatal familial insomnia, epilepsy, seizures, neurodevelopment, Tourette's syndrome, neuroinfectious disorders, meningitis, encephalitis, bovine spongiform encephalopathy, West Nile virus encephalitis, Neuro-AIDS, Fragile X syndrome, Guillain-Barré syndrome, brain metastases, or brain cancer, or others known to those skilled in the art. Some neurological disorders may also be categorized as proteopathies.

[0106] As used herein, the term "proteopathy" refers to a disease caused by the abnormal folding or accumulation of proteins. Abnormal proteins can acquire toxic functions or lose their normal functions. It is possible that misfolded proteins can induce misfolding of otherwise normally folded proteins, resulting in the amplification of disease (e.g., prion disease). Some non-limiting examples of proteopathies include Alzheimer's disease, cerebral beta-amyloid angiopathy, retinal ganglion cell degeneration in glaucoma, Parkinson's disease, Lewy dementia, multiple system atrophy, synucleinopathies, Pick's disease, corticobasal degeneration, tauopathy, frontotemporal lobar degeneration, Huntington's disease, dentatorubral-pallidoluysian atrophy, spinal and bulbar muscular atrophy, spinocerebellar ataxia, Fragile X syndrome, Baratella-Scott syndrome, Friedrich's ataxia, myotonic dystrophy, Alexander disease, familial British dementia, familial Danish dementia, Palizaeus-Merzbacher disease, and disease), seipinopathy, AA (secondary) amyloidosis, type II diabetes, fibrinogen amyloidosis, dialysis amyloidosis, inclusion body myositis / myopathy, familial amyloid neuropathy, senile systemic amyloidosis, serpinopathy, atrial amyloidosis, pituitary prolactinoma, insulin amyloidosis, corneal lactoferrin amyloidosis, pulmonary alveolar proteinosis, seminal vesicle amyloidosis, cutaneous lichen amyloidosis, Mallory bodies, or odontogenic (Pindborg) tumor amyloid, or any disease caused by protein misfolding or aggregation, or others known to one of skill in the art.

In particular, "Aβ" refers to any peptide produced by proteolytic processing of the amyloid precursor protein (APP) gene product, particularly peptides associated with amyloid pathology.

[0108] As used herein, the term "blood-brain barrier" has its plain and ordinary meaning as understood in light of the present specification and refers to the protective cellular boundary between the circulatory system and the central nervous system. This boundary is composed of closely interacting brain capillary endothelial cells (BCECs) of capillaries connected through tight junctions, which exhibit selectivity for different small and large molecules in addition to larger particles, such as circulating immune cells and pathogenic organisms. Generally, small polar or hydrophobic molecules can naturally diffuse through the blood-brain barrier, while larger and / or more polar molecules (e.g., glucose, proteins) require specific transporters expressed by endothelial cells to be able to cross the barrier. Some antibodies have been shown to be able to cross the blood-brain barrier by having specificity for cellular receptors or transporters on endothelial cells that internalize and undergo transcytosis. The BBB functions as a physical, metabolic, and immunological barrier. As disclosed herein, in some embodiments, the antibodies or binding fragments thereof disclosed herein may be able to cross the blood-brain barrier of a subject. In some embodiments, the subject may have an intact blood-brain barrier. In some embodiments, the subject may have a damaged or improperly functioning blood-brain barrier. In some embodiments, the damaged or improperly functioning blood-brain barrier is caused by neurodegenerative diseases, including but not limited to Alzheimer's disease, or is associated with brain cancer, such as primary and / or secondary brain tumor-related damage.

[0109] As used herein, the term "neuronal regeneration" has its plain and ordinary meaning as understood in light of the present specification and refers to the new proliferation (growth) of cells or components thereof associated with the nervous system. For example, regeneration can occur with the development of neurons, glia, oligodendrocytes, astrocytes, ependymal cells, microglia, or their components, such as axons, dendrites, myelin, or new synaptic / neuronal interactions. Neuronal tissue generally regenerates much slower than other tissues in adults, although some repair occurs after injury or damage. While there are currently no treatments to enhance neuronal regeneration, research is being conducted toward treatment and prevention, such as the prevention of neurodegeneration in diseases such as Alzheimer's disease and multiple sclerosis. As disclosed herein, in some embodiments, the antibodies or binding fragments thereof disclosed herein may be capable of promoting neuronal regeneration.

[0110] The terms "cancer," "neoplasm," "tumor," and "carcinoma" are used interchangeably herein to refer to cells that exhibit relatively autonomous growth and, as a result, an abnormal growth phenotype characterized by a significant loss of cell proliferation control. Generally, cells of interest for detection or treatment in this application include precancerous (e.g., benign), malignant, premetastatic, metastatic, and nonmetastatic cells. Detection of cancerous cells is of particular interest. The term "normal," when used in the context of "normal cells," is meant to refer to cells of a non-transformed phenotype or cells that exhibit the morphology of non-transformed cells of the tissue type being examined. A "cancerous phenotype" generally refers to any of a variety of biological phenomena characteristic of cancerous cells, which may vary with the type of cancer. A cancerous phenotype is generally identified by abnormalities, such as cell growth or proliferation (e.g., uncontrolled growth or proliferation), cell cycle regulation, cell mobility, cell-cell interactions, or metastasis.

[0111] The term "tumor microenvironment" refers to the cellular environment in which a tumor resides, which includes tumor cells as well as surrounding blood vessels, immune cells, fibroblasts, bone marrow-derived inflammatory cells, lymphocytes, signaling molecules, and the extracellular matrix.

[0112] The term "immune cells" refers to cells of hematopoietic origin that are involved in the specific recognition of antigens.

[0113] The term "immune response" refers to a T cell-mediated and / or B cell-mediated immune response. Exemplary immune responses include B cell responses (e.g., antibody production), T cell responses (e.g., cytokine production and cytotoxicity), and activation of cytokine-responsive cells, such as macrophages. The term "activating an immune response" refers to enhancing the level of a T cell-mediated and / or B cell-mediated immune response using methods known to those skilled in the art. In one embodiment, the level of enhancement is at least 20-50%, alternatively at least 60%, at least 70%, at least 80%, at least 90%, at least 100%, at least 120%, at least 150%, or at least 200%.

[0114] As used herein, the term "transforming growth factor beta receptor" (TGF-b receptor, or TGF-β receptor) refers to a family of serine / threonine kinase receptors expressed on the cell surface that are specific for the protein transforming growth factor beta (TGF-b, TGF-β).
