Anti-inflammatory effects of novel lipokines of fatty acid esters of hydroxy fatty acids family in obesity


The main objective  of this project is to explore  structure, mechanisms of action, anti-inflammatory  and anti-diabetic effects  of novel lipokines – branched fatty acid esters of hydroxy fatty acids  derived  from polyunsaturated fatty acids  of n-3 series (Omega-3) using obesity  and inflammation models.

Omega-3 polyunsaturated fatty acids (omega-3) of marine origin alleviate inflammation, while having favorable metabolic effects. Omega-3 reduce the risk of development of cardiovascular disorders that are linked to obesity and type 2 diabetes, and also improve lipid metabolism. A complex research of omega-3-related mechanisms of action in mouse models of obesity at the Institute of Physiology CAS, clinical research on obese patients with type 2 diabetes in the Institute for Clinical and Experimental Medicine, and a collaboration with the Institute of Organic Chemistry and Biochemistry CAS led to the identification of structures of novel signaling molecules of lipid origin - esters of fatty acids and hydroxyl-fatty acids (FAHFA) - derived from docosahexaenoic acid (DHA): 13-DHAHLA, 9-DHAHLA a 14-DHAHDHA. These molecules, which are synthesized by adipose cells and exert anti-inflammatory effects, were detected in the serum and adipose tissue of both obese mice and diabetic patients following dietary intervention with omega-3. These newly discovered molecules, which can be endogenously synthesized when eating an appropriate diet, are involved in the beneficial health effects of omega-3 and have the potential for their wide use in the prevention and treatment of severe diseases.

Chronic low-grade inflammation contributes to the development of diabetes, as well as cardiovascular, gastrointestinal and certain brain disorders. Lipids of marine origin help to prevent inflammatory diseases.
