resolvin e-1

Resolvin E1 is an effective endogenous pro-resolving mediator of inflammation. Resolvin E1 has unique counterregulatory actions that inhibit PMN transendothelial migration. Resolvin E1 also acts as an effective inhibitor of leukocyte infiltration, dendrit

Resolvin E2 (RvE2) is a member of the specialized pro-resolving mediator (SPM) family of bioactive lipids.1It is produced from eicosapentaenoic acidviaan 18-HEPE intermediate, which is formed by aspirin-acetylated COX-2-mediated oxidation of EPA, by 5-lipoxygenase (5-LO) in human polymorphonuclear (PMN) neutrophils.2,3RvE2 (20 ng/animal) inhibits increases in inflammatory exudate neutrophil infiltration in a mouse model of peritonitis induced by zymosan A .3Hepatic RvE2 levels are increased in mice fed normal chow, as well as in a mouse model of high-fat diet-induced non-alcoholic fatty liver disease (NAFLD), by dietary supplementation with EPA.4Plasma levels of RvE2 are increased by dietary supplementation with fish oil containing ω-3 polyunsaturated fatty acids (PUFAs) in patients with peripheral artery disease or chronic kidney disease.1,5,6 1.Chiang, N., and Serhan, C.N.Specialized pro-resolving mediator network: An update on production and actionsEssays Biochem.64(3)443-462(2020) 2.Tjonahen, E., Oh, S.F., Siegelman, J., et al.Resolvin E2: Identification and anti-inflammatory actions: Pivotal role of human 5-lipoxygenase in resolvin E series biosynthesisChemistry & Biology131193-1202(2006) 3.Sungwhan, F.O., Pillai, P.S., Recchiuti, A., et al.Pro-resolving actions and stereoselective biosynthesis of 18S E-series resolvins in human leukocytes and murine inflammationJ.

Resolvins are a family of potent lipid mediators derived from both eicosapentaenoic acid and docosahexaenoic acid . [1] In addition to being anti-inflammatory, resolvins promote the resolution of the inflammatory response back to a non-inflamed state.[2] Resolvin D5 (RvD5) is a DHA-derived resolvin generated by a double dioxygenation mechanism.[3] RvD5 has been identified in media from ionophore-stimulated trout brain cells, in human synovial fluid from patients with rheumatoid arthritis, and in exudates of bacterial infections in mice. [4][5][6] RvD5 stimulates the phagocytosis of E. coli by human macrophages, and RvD5 methyl ester enhances bacterial killing in mice inoculated with E. coli. [6] Analytical and biological comparisons of synthetic RvD5 with endogenously derived RvD5 have confirmed its identity as matching the natural product.[7]
