背景介绍

  • CD200 is a type-1 cell membrane glycoprotein of the immunoglobulin supergene family, present on both cells with myeloid/lymphoid origin as well as on epithelial cells and many cancer cells. CD200, also known as MRC OX-2, is a highly conserved, 48 kDa type 1a transmembrane glycoprotein related structurally to the B7 family of costimulatory receptors. The molecule itself consists of an IgSF extracellular domain (single V + C), a single transmembrane region and a short cytoplasmic tail lacking signaling motifs. The molecule is expressed by resting dendritic cells, thymocytes, endothelial cells, neurons and osteoblast precursors (OBp), as well as by activated B and T cells (including αβTCR+ and most γδTCR+ cells). CD200 interacts with a structurally related receptor (CD200R) expressed mainly on myeloid cells and is involved in regulation of macrophage and mast cell function. OX-2 / CD200 and CD200R associate via their respective N-terminal Ig-like domains. CD200 also plays an important role in prevention of graft rejection, autoimmune diseases and spontaneous abortion.
