They are G-protein coupled receptors that inhibit adenylyl cyclase and reduce neurotransmitter release, mainly located presynaptically and acting as autoreceptors. This review aims to examine the differential expression and function of group III mGluRs across various brain regions such as the cortex, hippocampus, and cerebellum, with a special focus on the neonatal stage of development. Glutamate excitotoxicity plays a crucial role in the pathophysiology of brain ischemia in neonates. While ionotropic glutamate receptors are traditional targets for neuroprotection, their direct inhibition often leads to severe side effects due to their critical roles in normal neurotransmission and synaptic plasticity. Group III mGluRs provide a more nuanced and potentially safer approach by modulating rather than blocking glutamatergic transmission. Their downstream signaling cascade results in the regulation of intracellular calcium levels, neuronal hyperpolarization, and reduced neurotransmitter release, effectively decreasing excitotoxic signaling without completely suppressing essential glutamatergic functions. Importantly, the neuroprotective effects of group III mGluRs extend beyond direct modulation of glutamate release influencing glial cell function, neuroinflammation, and oxidative stress, all of which contribute to secondary injury cascades in brain ischemia.
