Immunopharmacology Comments
CLEC4C (BDCA2) is a type 2 transmembrane protein that is selectively expressed by plasmacytoid dendritic cells (pDCs). Like other C-type lectins, this membrane protein has roles in inflammation and immune responses. It is reported to capture non-sialylated galactose-terminated complex glycan antigens [4] and present them to T cells [1]. Ligand binding to CLEC4C inhibits induction of interferon (IFN) α/β production in pDCs. Since pDC-derived IFN α/β is considered to be a major pathophysiological driver in systemic lupus erythematosus (SLE), CLEC4C is being investigated as molecular target for the treatment of autoimmune lupus diseases, both SLE and the cutaneous form [2].
