Direct T-cell Presentation by cDC1: The Key Feature for Cancer Vaccine Success?

In this issue of Cancer Immunology Research, Ferris and colleagues demonstrate that type 1 conventional DC (cDC1) vaccines drive tumor rejection through direct antigen presentation, without the need of endogenous cDC1. This suggests that cDC1-based vaccines could represent an optimal strategy to induce antitumor immunity in patients. See related article by Ferris et al., p. 920 (7) .
