GPR37 and ischemic stroke: The contribution of GPR37 L1 in microglial polarization and macrophage dynamics has not been investigated, but the combination of GPR37 L1′s high expression profile within astrocytes and the ability for astrocytic factors to modulate microglial responses following injury [70,71] could suggest a potential regulatory role for GPR37 L1 in the modulation of microglial responses following ischemic stroke.
