GPR17 is an orphan receptor that can be double-activated by uracil and cysteinyl-leukotriene (CysLT). It is phylogenetically related to both purinergic P2Y and CysLT receptors. GPR17 belongs to the superfamily of G-protein coupled receptors (GPCRs)4.
GPR17 expression is highly detected in the brain, kidney, and heart. In the brain, GPR17 is mainly distributed in white matter, gray matter, subependymal zone, and corpus callosum1.
Studies have shown that GPR17 receptor plays an important role in spinal cord injury, myelin sheath injury, cerebral ischemic injury, where its expression is extremely upregulated1,2.
GPR17 activation promotes oligodendrocyte differentiation and progression toward mature myelin-forming cells. Thus, GPR17 modulators may be used as therapeutic tools to treat pathologies associated with myelin repair in CNS demyelinating diseases3.
