Target Data

Function Inhibitory receptor for the CD200/OX2 cell surface glycoprotein. Limits inflammation by inhibiting the expression of proinflammatory molecules including TNF-alpha, interferons, and inducible nitric oxide synthase (iNOS) in response to selected stimuli. Also binds to HHV-8 K14 viral CD200 homolog with identical affinity and kinetics as the host CD200.

  12. data show that the expression of CD200R, CD95 and CD95L was influenced by cardiac surgery and imply the role of these membrane molecules in cell regulation-inhibition and apoptosis following cardiac surgery. PMID: 25404054
  13. The authors showed that the viral orthologues e127 from rat cytomegalovirus and K14 from human herpesvirus 8 do not bind the activating CD200R-like proteins from their respective species, although they do bind the inhibitory receptors. PMID: 26538068
  14. The proportion of CD200R1+ cells in PBMCs, peripheral CD14+ cells and CD4+ T cells was significantly lower in rheumatoid arthritis patients compared to controls. PMID: 25261692
