Description:This R6H1 monoclonal antibody reacts with CD196 (also known as CCR6), a seven transmembrane G protein-coupled receptor expressed on T, B, dendritic, natural killer, and Langerhans cells. This CC chemokine receptor uniquely binds MIP-3a/CCL20, a chemoattractant for dendritic cells, effector/memory T cells, and B cells. CD196 is also involved in host defense and inflammation at epithelial sites. Furthermore, this receptor has been implicated in Th17 differentiation and CD4+FoxP3+ regulatory T cell development.
