ABSTRACT
Myelination of axons in the central nervous system (CNS) is a concerted effort between many cell types, resulting in significant cross-talk and communication among cells. Adhesion G protein-coupled receptor ADGRG1 (GPR56) is expressed in all major glial cells and regulates a wide variety of physiological processes by mediating cell-cell and cell-matrix communications. Previous literature has demonstrated the requirement of ADGRG1 in oligodendrocyte precursor cells (OPCs) during developmental myelination. However, it is unknown if ADGRG1 is responsible for myelin formation in a cell-type-specific manner. To that end, here we profiled myelin status in response to deletion of Adgrg1 specifically in OPCs, microglia, astrocytes, and neurons. Interestingly, we find that knocking out Adgrg1 in OPCs significantly decreases OPC proliferation and reduced number of myelinated axons. However, deleting Adgrg1 in microglia, astrocytes, and neurons does not impact developmental myelination. These data support an autonomous functional role for Adgrg1 in OPCs related to myelination.
