Autocrine/paracrine TGFβ1 is required for the development of epidermal Langerhans cells
15 Oct 2007
Abstract excerpt
Langerhans cells (LCs) are bone marrow (BM)-derived epidermal dendritic cells (DCs) that develop from precursors found in the dermis. Epidermal LCs are absent in transforming growth factor (TGF) beta1-deficient mice. It is not clear whether TGFbeta1 acts directly on LC precursors to promote maturation or whether it acts on accessory cells, which in turn affect LC precursors. In addition, the physiologic source of...
