Data Sheet

Background: Epstein-Barr virus-induced gene 2 (EBI2, also known as GPR183) is a GPCR required for humoral immune responses and polymorphisms have been associated with inflammatory autoimmune diseases. It is expressed in B-lymphocyte cell lines as well as lymphoid tissues but not T-lymphocyte cell lines or peripheral blood T-lymphocytes. 7α,25-dihydroxycholesterol (7α,25-OHC) and other oxysterols act as chemoattractants for immune cells expressing EBI2 by directing cell migration. Mice deficient in cholesterol 25- hydroxylase (CH25H, required for generation of 7α,25-OHC) fail to generate EBI2 biological activity in vivo and shows that the EBI2-oxysterol signaling pathway plays an important role in the adaptive immune response.
