This system regulates extracellular glutamate concentrations through non-vesicular release, establishing a vital feedback loop: the released glutamate activates presynaptic group II metabotropic receptors (mGluR2/3), which in turn inhibit vesicular glutamate release and offer protection against N-methyl-D-aspartate receptor (NMDAR)-mediated excitotoxicity (Figure 2) [8,69,70,71]
