| Summary |
Cancer vaccines utilizing naturally circulating dendritic cell (DC) subsets, such as plasmacutoid DCs (pDCs) and type 2 convential DCs (cDC2s), have demonstrated their potential as a therapy. For melanoma in recent clinical trials. These DC vaccines aim to. human. DC subsets on the. T cell transcriptional program, which. forms the. molecular. basis. of an. antitumor. T cell response, is. poorly understood. In. this study, we investigated the eraly gene expressionsignature of CD8+ T. cells following. stimulation by pDCs or cDC2s. in. a culture system that mimics. the. current protocol of primary DC-based cancer vaccines. Our results demonstrate that pDCs and cDC2s induce a remarkably similar transcriptomic profile in CD8_ T cells, which. is tailored for increased effector function, survival and sensitivity. towards secondary signals. Nonetheless, differences between pDC- and cDC2-induced T cell gene expression signatures encompass genes with a role in proliferation, cytolytic capacity and differentiation. Combining both DC subsets results in a T cell. transcriptomic program that. is very. similar to. the program induced by. pDCs alone. The results suggest that the. choice of DC subsets for use in cancer vaccines impacts the induced antitumor CD8+ T cell response.
