Attenuation of adipose tissue inflammation by pro-resolving lipid mediators

Abstract

Adipose tissue inflammation drives systemic pathophysiology, for instance, obesity-related cardiometabolic disease. Specialized pro-resolving lipid mediators are a superfamily of endogenously produced lipids that promote the resolution of inflammation, an actively regulated process. New evidence suggests that such lipids (e.g. lipoxins) could resolve adipose tissue inflammation and, thus, subvert obesity-related diseases. A key feature of pro-resolving lipids is their ability to promote an M2-like macrophage phenotype and enhance efferocytosis while avoiding adverse side-effects typically associated with anti-inflammatory drugs, such as increased sensitivity to infections. This brief review discusses the therapeutic potential of pro-resolving lipid mediators in mitigating systemic disease fueled by adipose tissue inflammation in both experimental and human disease models.
