Free fatty acid receptor 2 (FFAR2), also known as G-protein coupled receptor 43 (GPR43), functions as the cell membrane receptor for short chain fatty acids that ultimately stimulates G protein coupled, inhibitory (Gi) signals via the adenylate cyclase pathway. FFAR2/GPR43 is found expressed in leukocytes in the lamina propria of the small intestine mostly but some expression can be also be found in splenocytes, adipose tissue, and enteroendocrine cells of the gut. Interesting, FFAR2/GPR43 because it senses short chain fatty acids which are often key metabolites of gut microbiota, it may serve as a biological sensor to regulate the activity of regulatory T cells and the immune response in diseases such as colitis.
