Abstract

While multiple pathways of dendritic cell (DC) maturation result in transient production of IL-12, fully mature DCs show reduced ability to produce IL-12p70 upon a subsequent interaction with Ag-specific T cells, limiting their in vivo performance as vaccines. Such “DC exhaustion” can be prevented by the presence of IFNγ during the maturation of human DCs (type-1-polarization), resulting in improved induction of tumor-specific Th1 and CTL responses in vitro. Here, we show that type-1 polarization of mouse DCs strongly enhances their ability to induce CTL responses against a model tumor antigen, OVA, in vivo, promoting the induction of protective immunity against OVA-expressing EG7 lymphoma. Interestingly, in contrast to the human system, the induction of mouse DC1s requires the participation of IL-4, a nominal Th2-inducing cytokine. The current data help to explain the previously reported Th1-driving and anti-tumor activities of IL-4, and demonstrate that type-1 polarization increases in vivo activity of DC-based vaccines.
