A Non-Internalizing Anti-CD40 Antibody, CHIR-12.12, Blocks CD40L-Induced Cytokine Production and Mediates Greater ADCC Than Rituximab in Primary CLL Cells.
Abstract:CD40 is expressed on chronic lymphocytic leukemia (CLL) cells, and CD40 activation leads to signaling critical for cell survival and proliferation. We have previously described a novel, fully human IgG1 anti-CD40 antagonistic monoclonal antibody, CHIR-12.12, generated in XenoMouse® mice (Abgenix, Inc.), and have demonstrated that it inhibits normal human B cell proliferation and survival and mediates potent antibody-dependent cellular cytotoxicity (ADCC) against primary CLL and non-Hodgkin’s lymphoma cells.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
