"Nature" discovered a new hormone, which has an important relationship with diabetes and obesity!
A hormone complex of the protein FABP4 and nucleoside kinases regulates islet function. Fat cells secrete a molecule called fatty acid binding protein 4 (FABP4) during lipolysis, which is involved in the composition of the protein complex fabkin1. Abnormal or chronic lipolysis can damage islet B cells and lead to type 1 diabetes. Can be cured. This article is a paper on basic medical research related to diabetes, obesity, cardiovascular endocrine and metabolic diseases, etc.

摘要:The liberation of energy stores from adipocytes is critical to support survival in times of energy deficit; however, uncontrolled or chronic lipolysis associated with insulin resistance and/or insulin insufficiency disrupts metabolic homeostasis1,2. Coupled to lipolysis is the release of a recently identified hormone, fatty-acid-binding protein 4 (FABP4)3. Although circulating FABP4 levels have been strongly associated with cardiometabolic diseases in both preclinical models and humans4,5,6,7, no mechanism of action has yet been described8,9,10. Here we show that hormonal FABP4 forms a functional hormone complex with adenosine kinase (ADK) and nucleoside diphosphate kinase (NDPK) to regulate extracellular ATP and ADP levels. We identify a substantial effect of this hormone on beta cells and given the central role of beta-cell function in both the control of lipolysis and development of diabetes, postulate that hormonal FABP4 is a key regulator of an adipose–beta-cell endocrine axis. Antibody-mediated targeting of this hormone complex improves metabolic outcomes, enhances beta-cell function and preserves beta-cell integrity to prevent both type 1 and type 2 diabetes. Thus, the FABP4–ADK–NDPK complex, Fabkin, represents a previously unknown hormone and mechanism of action that integrates energy status with the function of metabolic organs, and represents a promising target against metabolic disease.
