Edg2 receptor distribution in adult rat brain.
The Edg (endothelial differentiation gene) receptors are recently discovered G-protein coupled receptors which are activated by endogenous lysophospholipids. The cellular activities mediated by Edg receptors are reminiscent of those normally associated with Trk receptor activation and include modulation of cell growth, differentiation, proliferation and migration as well as apoptotic and cytoskeletal effects. In this study we have investigated immunohistochemically the distribution of one family member, the Edg2 receptor, within the adult rat brain and shown the protein expression to be most prominent in white matter tract regions. This suggests a possible role for the Edg2 receptor in nerve cell myelination.
