Abstract: The present application provides methods of treating a cancer in an individual that involves administering to the individual a tyrosine kinase inhibitor and a pro-inflammatory agent (such as a TLR agonist, a STING activator, a radiation therapy, or an immune checkpoint inhibitor). In some cases, the methods involve administering a tyrosine kinase inhibitor when the individual is under an inflammation reaction.

Abstract: As disclosed herein, SIRP? is integral to immuno-evasion by many different cancer types as well as cancer resistance to therapies, and reducing SIRP? levels on can bolster antigen acquisition, processing, and presentation, decrease TME immunosuppression and thereby promote tumor-specific T cell activation to eliminate tumors and generate an adaptive immune response consisting of memory T cells, circulating antibodies, and plasma cells, all of which may be specific for neo-antigens in the original cancer. Therefore, disclosed are activated SIRP?low macrophages that are useful for treating cancers.

Abstract: The present application provides compositions and methods for producing antigen presenting cells (APCs) from monocytes (e.g., monocytes from cancer patients) that involve an IL-10 receptor activator (e.g., IL-10), IFN? receptor activator (e.g., IFN?), TNF? receptor activator (e.g., TNF?), IL-4 receptor activator (e.g., IL-4), GM-CSF receptor activator (e.g., GM-CSF), and/or IL-6 receptor activator (e.g., IL-6). APCs produced accordingly are also provided, as well as methods of activating immune cells (e.g., T cells) via co-culturing with APCs. The activated immune cell compositions and the methods of treatments that involve the activated immune cells are also provided.

Abstract: The present invention relates to compositions and methods variously useful in treating cancer, inhibiting graft rejection, and treating autoimmune disease. The compositions and methods include those in which macrophages are conditioned to down regulate or upregulate the expression or activity of SIRP? or its interaction with CD47.
