CD4+ T cells produce IFN-I to license cDC1s for induction of cytotoxic T-cell activity in human tumors

Abstract excerpt

Abstract CD4 + T cells can "help” or "license” conventional type 1 dendritic cells (cDC1s) to induce CD8 + cytotoxic T lymphocyte (CTL) anticancer responses, as proven in mouse models. We recently identified cDC1s with a transcriptomic imprint of CD4 + T-cell help, specifically in T-cell-infiltrated human cancers, and these cells were associated with a good prognosis and response to PD-1-targeting immunotherapy....
