Figure 1. TGFβ1 impacts on dendritic cell differentiation. (A) Autocrine and paracrine transforming growth factor β1 (TGFβ1) production in the epidermis by Langerhans cells (LCs, red) and keratinocytes (blue). (B) TGFβ1 produced by stromal cells (blue) impacts on multipotent progenitor cells (MPPs) and committed dendritic cell precursors (CDPs) during dendritic cell (DC) commitment and differentiation into conventional and plasmacytoid DCs (cDCs and pDCs, respectively). (C) TGFβ1 induces the expression of Id2, Irf4, Irf8 and Runx3, which are key transcription factors for DC development.
