Research summary
Cancer immunotherapies have revolutionized the treatment of malignancies, but these therapeutics still face enormous challenges and limited efficacy in many patients. To overcome these limitations, improved strategies for CD8 T cell-targeted therapies require an increased understanding of how other immune players, particularly CD4 helper T cells, can promote cytotoxic CD8 T cell responses against cancer neoantigens. Conventional type 1 dendritic cells (cDC1) are thought to perform antigen cross-presentation, which is required to prime CD8 T cells. We have recently shown that cDC1 also prime CD4 T cells in the context of tumor antigens. CD4 T cells are also considered to help CD8 T cell responses through a variety of mechanisms, including a process whereby CD4 T cells ‘license’ cDC1 in a CD40-dependent pathway. My research seeks to determine the functions of cDC1 in initiating CD4 and CD8 T cell anti-tumor responses and the downstream mechanisms of CD40 signaling in the cDC1.
