TSLP + TGF-β LC expression of macrophage and DC subset markers, maturation markers, and skin-homing receptors. Representative histograms of the expression of (A) macrophage and DC subset molecules, (B) activation markers, and (C) skin-homing receptors by sorted human blood BDCA-1⁺ cells after a 24-hour culture with or without TSLP or TGF-β. Data on BDCA-1⁺ DCs treated with both TSLP and TGF-β correspond to the CD1a⁺ CD207⁺ cells. Plain histograms represent the matching corresponding isotype controls, and numbers represent specific MFIs; n = 4 to 11.
