Figure 6. A proposed mechanism for astrocytic glutamine release.

Figure 6

Activation of glial glutamate transporters (EAATs) causes a rise in glial [Na+]i, which favours the efflux of glutamine via glial system N transporters (SN). Released glutamine is subsequently detected by system A transporters (SA) located on adjacent MNTB neurones, resulting in a neuronal glutamine transport current.
