Abstract 5079: Intratumoral CD40 agonist enhances the antitumor effect of anti-PD1 immunotherapy by activation of antigen-presenting cells and selective expansion of effector CD8+ T cells
Abstract:Agonistic CD40 antibodies have shown promise when used in combination with checkpoint inhibitors in clinical trials for the treatment of malignancies. However, the mechanisms driving antitumor immune responses in patients are not well understood. The aim of this study was to use a preclinical melanoma model to evaluate the impact of intratumoral anti-CD40 administration on treatment efficacy and the tumor immune landscape in the context of systemic anti-PD1 therapy. Mice bearing 8-day established B16 melanoma … Show more
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.
