Abstract: The present application features antibodies that bind to human neonatal Fc receptor (FcRn). These anti-FcRn antibodies are useful, e.g., to promote clearance of autoantibodies in a subject, to suppress antigen presentation in a subject, to block an immune response, e.g., block an immune complex-based activation of the immune response in a subject, and to treat immunological diseases (e.g., autoimmune diseases) in a subject. These anti-FcRn antibodies are also useful, e.g., to decrease pathogenic antibody transport across the placenta of a pregnant subject, to increase pathogenic antibody catabolism in a pregnant subject, and to treat an antibody-mediated enhancement of viral disease in a fetus or a neonate.

Abstract: The invention relates to an isolated immunoglobulin heavy chain polypeptide and an isolated immunoglobulin light chain polypeptide that bind to a protein encoded by the interleukin 36 receptor (IL-36R). The invention provides an IL-36R-binding agent that comprises the aforementioned immunoglobulin heavy chain polypeptide and immunoglobulin light chain polypeptide. The invention also provides related vectors, compositions, and methods of using the IL-36R-binding agent to treat a disorder or disease that is responsive to IL-36R inhibition, such as cancer, an infectious disease, or an autoimmune disease.

Abstract: Provided are antibodies and antigen binding fragments thereof that bind to human interleukin-11 receptor subunit ? (IL-11R?) and related compositions, which may be used in any of a variety of therapeutic or diagnostic methods, including the treatment or diagnosis of cancers, inflammatory diseases, autoimmune diseases, and others.

Abstract: Provided are antibodies that bind to interleukin-18 binding protein (IL-18BP) and related compositions, which may be used in any of a variety of therapeutic or diagnostic methods, including the treatment or diagnosis of cancers and other diseases.

Abstract: Provided herein are anti-T Cell Immunoglobulin and Mucin Protein-3 (TIM-3) antibodies having particular immunoglobulin heavy chain polypeptide and immunoglobulin light chain polypeptide sequences and methods of using the anti-TIM-3 antibodies to treat a disorder or disease that is responsive to TIM-3 inhibition, such as cancer, an infectious disease, or an autoimmune disease.

Abstract: Provided are antibodies and antigen binding fragments thereof that bind to human interleukin-11 receptor subunit ?
