Abstract:
G-protein-coupled receptors (GPCRs) are a major class of membrane proteins involved in numerous physiological and pathological processes. Among them, free fatty acid receptor 4 (FFAR4/GPR120), activated by long-chain free fatty acids, has shown anti-inflammatory effects and is expressed in the brain-implicating its role in neurodegenerative diseases like Alzheimer's disease (AD). AD is characterized by brain atrophy, cognitive decline, and neuroinflammation, involving complex signaling networks. This review explores the pharmacological relevance of GPR120/FFAR4 in AD, focusing on its involvement in neuroinflammatory, amyloidogenic, and intracellular signaling cascades. Targeting GPR120 may help modulate chronic inflammation and amyloid-β accumulation. Additionally, activation of nuclear receptors and regulation of pathways such as MAPK, NLRP3, PPARs, and cAMP have shown promise in mitigating AD pathology. Despite the complexity of brain signaling, GPR120 emerges as a compelling multitarget therapeutic receptor. These insights provide a foundation for developing novel anti-inflammatory strategies in AD treatment.
