Suggested mechanisms for astrocytic and microglial release of BDNF. Glial BDNF release is dependent on GPCR activation and Ca2+-release from internal Ca2+-stores (a) and on Ca2+-influx via P2X-R (b). AC adenylate cyclase, DAG diacylglycerol, ER endoplasmatic reticulum, IP3 inositol triphosphate, IP3R inositol-3-phosphate receptor, p38MAPK p38-mitogen-activated protein kinase; P2XR purinergic P2X receptor, PKA protein kinase A, PLC phospholipase C; TRPC transient receptor potential channel
