Skin-derived DCs in the draining lymph nodes are significantly reduced in GM-CSF– and FL-deficient mice in steady state. (A) Flow cytometry and analysis of DC subsets in skin-draining LNs (pooled inguinal, axillary, and cervical LNs). Horizontal lines indicate mean values of the results. LN DC subsets gated as CD40hiCD11cint, CD40+CD11chi, and CD40−CD11cint. Total LN cell numbers (A) and percentage of each LN DC subset (B) are shown in graphs. *P < .05; **P < .01.
