FFAR2

FFAR2

A gene on chromosome 19q13.1 that encodes a member of the GP40 family of G protein-coupled receptors that is a receptor for short-chain free fatty acids. FFAR2 may be involved in the inflammatory response and in regulating lipid plasma levels.

Targeting Ffar2 (GPR43) and Ffar3 (GPR441) and down-regulating NF-?B, this patent covers the company's first major drug, SFA001, and provides a way of treating patients afflicted with hepatitis B.

found that SCFA butyrate suppressed colonic stem cell proliferation [112], perhaps through receptors encoded by Ffar3, Ffar2, and Niacr1 [113].
GPR41 (i.e., FFAR3) and GPR43 (i.e., FFAR2) are both highly expressed on immune cells such as polymorphonuclear cells and macrophages [ 22].
SCFAs can stimulate glucagon-like peptide 1 (GLP-1) secretion via the G-protein-coupled receptor FFAR2 (free fatty acid receptor 2) in the colonic mucosa (44).
Receptors for SCFAs are two Gprotein coupled receptors (GPCRs): FFAR2 (free fatty acid receptor2, previously known as GPR43) and FFAR3 (or GPR41) [37-40].
Deficiency of FFAR2 results in increasing or maintaining inflammation in models of colitis, arthritis, and asthma, related to increased production of inflammatory mediators and increased immune cell recruitment [48].
Expression of both FFAR2 and FFAR3 was reported in the colon, with particularly strong expression in GLP-1 producing L-cells [42-44, 64].
The poor responsiveness to SCFAs of the GLP1, secreting cell line GLUTag, has been associated with the very low expression of FFAR2 [49].
