Overview of Gene Research
Ffar3, also known as GPR41, is a G protein-coupled receptor activated by short-chain fatty acids (SCFAs), mainly acetate, butyrate, and propionate [2]. It is involved in multiple physiological functions such as metabolism and immune response regulation, and is part of the microbiota-gut-brain axis [2,3].
In a study, young mice with intestine-specific loss of FFAR2/3 exhibited gut and brain abnormalities similar to those in older mice. This indicates that reduced FFAR2/3 signaling, including that of Ffar3, due to low butyrate levels caused by a decline in butyrate-producing bacteria in aged gut microbiota, leads to increased gut permeability, inflammation, and brain abnormalities [1]. In another study, global knockout FFAR3 (Ffar3(-/-)) mouse islets secreted more insulin in a glucose-dependent manner compared to wild-type islets, suggesting that FFAR3 signaling inhibits glucose-dependent insulin secretion through a Gαi/o pathway [4].
In conclusion, Ffar3 plays a crucial role in maintaining gut-brain health and regulating insulin secretion. The use of Ffar3 knockout mouse models has revealed its significance in age-related cognitive decline and metabolic regulation, providing insights into potential therapeutic strategies for age-associated diseases and diabetes [1,4].
