- GPR120 is a receptor for omega-3 fatty acids and is expressed in the CNS on microglia, astrocytes, and neurons.
- Activation of GPR120 inhibits neuroinflammation via β-arrestin2, suppressing NF-κB and NLRP3 inflammasome pathways.
- GPR120 signaling also regulates mitophagy and reduces endoplasmic reticulum stress, promoting neuronal survival.
- GPR120 activation shows neuroprotective effects in epilepsy, Alzheimer's disease, stroke, and depression models.
- Preclinical studies support the efficacy of selective GPR120 agonists like TUG-891 and CpdA.
- Clinical translation faces challenges including species differences, weak ligands, high protein binding, and lack of clinical trials.
- Future research should focus on species differences, brain-targeted delivery, and advancing translational studies.
