Fig 1: Induction of langerin in CD1c+ blood myeloid DCs.(A) Langerin induction on whole-cultured PBMC after 18 h (T18) of culture in vitro, with or without TGF-β, compared with isotype control. DCs and monocytes were identified by the gating strategy shown and the expression of langerin displayed below. Representative example of 4 experiments. (B) Langerin induction on sorted monocytes and blood DCs after 18 h of culture in serum containing medium and TGF-β. *P < 0.05; **P < 0.01. Mean of 4 experiments. (C) Expression of langerin mRNA by CD14+ monocytes (blue bars) and CD1c+ blood DCs (red bars) at 0 h and 18 h with TGF-β. One of 3 experiments is shown. (D) Inhibition of langerin induction in serum containing medium and TGF-β by an ALK-3-Fc chimeric-blocking agent. One of 3 experiments is shown.
