Abstract
CD200 and its receptor, CD200R, constitutes an endogenous inhibitory signaling, and is being increasingly recognized in studies of various central nervous system (CNS) disorders. Emerging data have demonstrated that neuronal CD200 binds to CD200R to modulate immune responses to pathogenic stimuli. However, on which component of the immune response that CD200-CD200R signaling acts is not well understood. In this review, we focused on cellular expression of the signaling, the effects on immune cell activation, and the function in pathological procedures of neurodegenerative diseases, in both clinical and experimental disease models. Essential functions of CD200-CD200R interaction and the treatment relevance have been elaborated. Immune responses to diseases under the control of CD200-CD200R axis were also discussed in the review.
