The present invention is directed to antibodies and fragments thereof (especially chimeric and humanized) having binding specificity for HGF and their use in therapy and diagnosis. These antibodies inhibit or block HGF-associated activities including HGF's effects on cell proliferation, invasion, angiogenesis, metastasis and fibrosis. Particularly the antibodies may be used as a monotherapy or in combination therapies in treating cancer, other proliferative disorders and other conditions wherein inhibition of HGF and/or the HGF/HGF-R (c-met) interaction is desired.

The invention provides monoclonal antibodies that specifically bind to TIGIT. The monoclonal antibodies have the capacity for substantial activation of T cells and natural killer cells by inhibiting binding of TIGIT to CD155. The monoclonal antibodies can be used for treatment of cancer and infectious disease, among other applications.

Disclosed herein are methods of increasing response to radiation therapy in subjects afflicted with cancer. In some embodiments, the method comprises reducing the ability of an immune suppressor cell (e.g., MDSC) to migrate to the microenvironment of the cancer. In some embodiments, the method further comprises suppressing the migration of the immune suppressor cell to a non-malignant cell and/or suppressing the malignant transformation of the non-malignant cells.

The present invention relates to an anti-Notch 3 antibody therapy useful for treatment of patients with cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy. In particular, the invention relates to an anti-Notch3 antibody or a fragment thereof having a 2 fold, 4 fold or 10 fold higher affinity to Notch 3 than to Notch 1 or Notch 2 for use in therapy.

Provided herein, inter alia, are isolated antibodies that bind an extracellular domain of a human SIRP-α v1 polypeptide (e.g., the D1 domain), an extracellular domain of a human SIRP-α v2 polypeptide, or both. In some embodiments, the antibodies also bind an extracellular domain of a monkey SIRP-α polypeptide, an extracellular domain of a mouse SIRP-α polypeptide, an extracellular domain of a human SIRP-β polypeptide, and/or an extracellular domain of a human SIRP-γ polypeptide. In some embodiments, the antibodies block or do not binding between an extracellular domain of a human SIRP-α polypeptide and an IgSF domain of a human CD47 polypeptide, while in some embodiments, the antibodies reduce the affinity of a human SIRP-α polypeptide for binding an IgSF domain of a human CD47 polypeptide. Further provided herein are methods, polynucleotides, vectors, and host cells related thereto.

The present application relates to anti-LOX and anti-LOXL2 antibodies and their use in purification, diagnostic and therapeutic methods. Antibodies include monoclonal antibodies, humanized antibodies and functional fragments thereof. Anti-LOX and anti-LXL2 antibodies can be used to identify and treat conditions such as a fibrotic condition, angiogenesis, or to prevent a transition from an epithelial cell state to a mesenchymal cell state.

Provided herein are compositions, methods and uses involving antibodies that bind to ErbB, a receptor tyrosine kinase, and modulate the activity of ErbB. Also provided are uses and methods for treating disorders, such as cancer, by administering to subject an antibody that binds to ErbB.

The present invention relates to rapid clearance molecules that bind target antigens and FcγRIIb with increased affinity as compared to parent molecules, the compositions being capable of causing accelerated clearance of such antigens. Such compositions are useful for treating a variety of disorders, including allergic diseases, atherosclerosis, and a variety of other conditions.

Disclosed herein are compositions comprising one or more antibodies that specifically bind active plasma kallikrein (e.g., human plasma kallikrein) and methods of using such compositions for the treatment of retinal diseases, such as diabetic macular edema.

The invention relates to antibodies against carcinoembryonic antigen (CEA) which have a direct cell growth inhibition activity on tumor cells expressing CEA and to their use for the treatment and diagnosis of cancer.
