Abstract

See full text

Compositions and methods are provided for blocking Tim4 on the surface of myeloid cells in order to treat and prevent cancer in a subject. Blocking Tim4 on the surface of myeloid cells can restore anti-tumor immunity and reduce the uptake of apoptotic cells. Further, by administering an anti-Tim4 antibody, the pro-inflammatory anti-tumor response can be increased. Accordingly, methods for reducing the uptake of apoptotic cells and methods for increasing anti-tumor immunity are provided herein. The present disclosure further describes a method for producing monoclonal antibodies that bind Tim4 on the surface of myeloid cells. The anti-Tim4 antibodies can further be selected for their ability to inhibit engulfment of dead or dying cells, to elicit the production of inflammatory cytokines, and to restrict the growth of tumors.
