Accordingly, the control of extracellular levels of glutamate dictates its physiological/pathological actions and this equilibrium is maintained primarily by the action of glutamate transporters (such as GLAST, GLT1, and EAAC1) located on astrocytic cell membranes, which remove the excitatory neurotransmitter from the synaptic cleft, keeping its extracellular concentrations below toxic levels (Anderson and Swanson, 2000
It was initially identified on the basis of three unique properties: its mediation of the skeletal growth-promoting actions of GH, its mitogenic properties, and its mimicry of the actions of insulin
