HAVCR2 and neoplasm: In Batf3<sup>-/-</sup> mice lacking cDC1s, anti-Tim-3-based vaccines still elicited significant CD8 T cell cross-priming and tumor control-albeit both were reduced compared to wild-type mice- demonstrating that cDC1s contribute to but are not essential for Tim-3-targeted vaccine-induced CD8 T cell priming and anti-tumor efficacy.
