title: Regulating with Reg proteins: a new role in Th17 cell-mediated skin inflammation.
abstract: The mechanisms linking skin inflammation and observed defects in skin barrier function and integrity need further elucidation. In this issue of Immunity, Lai et al. (2012) identify REG3A as a downstream mediator of interleukin 17A that enhances keratinocyte proliferation and downmodulates keratinocyte differentiation.
