Outline of Final Research Achievements

We report that short-chain fatty acid receptor GPR43 is abundantly expressed in adipose tissues and GPR43-deficient mice are obese on a normal diet, whereas mice overexpressing GPR43 specifically in adipose tissue remain lean. We further report that short-chain fatty acid-mediated activation of GPR43 suppresses insulin signalling in adipocytes, which inhibits fat accumulation in adipose tissue and promotes the metabolism of unincorporated lipids and glucose in other tissues. Recently, we confirmed that GPR43 was expressed in macrophage in adipose tissue inflammation.
