Clec4A4 is a regulatory receptor for dendritic cells that impairs inflammation and T-cell immunity

Abstract

Clec4A4 is a C-type lectin receptor highly expressed by CD8α− dendritic cells. Here the authors show that its loss of function results in enhanced T cell responses and exacerbated autoimmunity, implicating Clec4A4 in limiting activation of the CD8α−dendritic cells.
