Fully developed cDCs or pDCs, if free of NK cells or IKDCs, showed little capacity for IFN- production. However, an early developmental form of the CD4–8+ cDC subtype, and the Ly6C– Ly49Q– pDC subtype, both were able to produce moderate amounts of IFN-, although less than IKDCs. In response to toll-like receptor 9 stimuli, both the Ly6C+ Ly49Q+ and the Ly6C– Ly49Q– pDC subtypes were effective producers of IFN-. However, IKDCs, which efficiently produced IFN- and showed immediate cytotoxicity on NK target cells, did not produce IFN- un-der these conditions.
