Activation status of human SLN cDC subsets. Percentages (left) and the MFIs (right) of (A) costimulatory (CD40, CD83, CD80, CD86) (n = 14) and (B) coinhibitory (B7H1 and B7H4) (n = 3) surface receptors. *P < .05 in 1-way ANOVA with post hoc multiple comparison Tukey test. Numbers indicate the significant difference compared with the (1) CD11c^hi CD1a^int, (2) CD11c^int CD1a^hi, (3) CD11c⁺CD1a⁻CD14⁻, and (4) CD11c⁺CD1a⁻CD14⁺ subsets.
