Schematic representation of the signaling pathway mediated by GABAB receptor in CGN neuroprotection. Activation of GABAB receptor leads to the release of Gβγ subunits from Gi/o-protein to activate PLC/Ca2+-dependent FAK1 pathway, which in turn transactivates IGF-IR to induce Akt phosphorylation through the Src family kinases.
