Abstract: The present invention is based on the finding that CD11b signaling inhibits immune suppression, modulates neovascularization and promotes anti-tumor immune responses in models of murine and human cancer. As such, provided herein are methods of treating cancer using an antibody, protein or small molecule that modulates CD11b activity or expression. Also provided are methods of identifying cancer that is amenable to such treatment and/or increasing susceptibility of cancer cells to treatment with a chemotherapeutic agent.

Abstract: The present disclosure relates to PI3K? inhibitors and methods of their use.

Abstract: The present invention is directed to compositions and methods for inhibiting the development of new lymphatic vessels, and for inhibiting tumor cell dissemination through the lymphatics. In preferred embodiments, the present invention utilizes agents that inhibit the specific binding of integrin alpha4beta1 (?4?1, VLA-4) to one or more of its ligands. The invention further relates to methods for screening test compounds for their ability to inhibit undesirable lymphangiogenesis and/or tumor metastasis.

Abstract: The invention relates to methods for detecting and inhibiting angiogenesis, cell migration, cell adhesion, and/or cell survival in endothelial and non-endothelial cells as well as in normal and tumor cells. The invention further relates to methods for screening test compounds for their ability to inhibit angiogenesis, cell migration, cell adhesion, and/or cell survival.

Abstract: The invention provides methods for detecting and inhibiting angiogenesis, endothelial cell adhesion, and endothelial cell migration using agents which inhibit the specific binding of integrin ?4?1 to one or more of its ligands. The invention further provides methods for screening test compounds for their ability to inhibit angiogenesis, endothelial cell adhesion, or endothelial cell migration by employing agents which inhibit the specific binding of integrin ?4?1 to one or more of its ligands. The invention additionally relates to methods for isolating endothelial progenitor cells which express integrin ?4?1. The methods of the invention are useful in, for example, diagnosing and inhibiting pathological conditions that are associated with angiogenesis, endothelial cell adhesion, and/or endothelial cell migration.

Abstract: The invention is directed to a method for inhibiting angiogenesis and thus treating inflammatory diseases (e.g., rheumatoid arthritis, diabetic retinopathy, psoriasis, and macular degeneration), inhibiting and preventing tumor growth and preventing metastases in a mammal comprising administering to the mammal an effective amount of a monoclonal antibody which is an antagonist of the integrins, GPIIb/IIIa (&agr;IIb&bgr;3) and &agr;v&bgr;3.
