PDC and infection: Depletion of pDCs in these FLT3L treated mice resulted in reduced inflammation and BALF cell counts 3 days after infection (Figure 6A and B), as well as a significant reduction in IL-12p40, IFN-γ, and IL-6 concentrations in both the BALF and lung homogenates after pDC depletion (Figure 6C and D).
