DCs subsets may differently affect NK cell function. Distinct DC subsets reflect different capability to promote NK cell function: IL-15 released by LC may promote NK cell proliferation; IL-12, mainly produced by CLEC9A+/BDCA3+ DCs and BDCA1+ DCs, induces IFN-γ release and subsequent Th1 polarization of T cells; NK cytolytic activity may be boosted by IFN-α secreted by pDCs and CLEC9A+/BDCA3+ DCs.
