GPR 120

GPR 120 is a G protein-coupled receptor (GPCR) and the putative receptor for omega-3 fatty acids including Docosahexaenoic acid (DHA) and Eicosapentaenoic acid (EPA).[1][2] GPR 120 was among a number of free fatty acid receptors only recently discovered from the human genome database utilizing the GPCR deorphanizing strategy.[3] Binding to the GPR 120 receptor is one of the many putative mechanisms of action for the potential health benefits of consuming omega-3 fatty acids. GPR 120 has specifically shown a role in the in-vivo anti-inflammatory and insulin-sensitizing effects of DHA and EPA in macrophages. Macrophage mediated inflammation is a key player in the pathophysiology of metabolic syndrome related disorders, including diabetes and atherosclerosis. GPR 120 is also a key regulator of adipogenesis, including adipocyte development and differentiation.[4]
