microRNAs as a New Mechanism Regulating Adipose Tissue Inflammation in Obesity and as a Novel Therapeutic Strategy in the Metabolic Syndrome

الملخص EN

Obesity is associated closely with the metabolic syndrome (MS).

It is well known that obesity-induced chronic inflammation plays a fundamental role in the pathogenesis of MS.

White adipose tissue (AT) is the primary site for the initiation and exacerbation of obesity-associated inflammation.

Exploring the mechanisms of white AT inflammation and resetting the immunological balance in white AT could be crucial for the management of MS.

Several prominent molecular mechanisms have been proposed to mediate inflammation in white AT, including hypoxia, endoplasmic reticulum stress, lipotoxicity, and metabolic endotoxemia.

Recently, a growing body of evidence supports the role of miRNAs as a new important inflammatory mediator by regulating both the adaptive and innate immunity.

This review will focus on the implication of miRNAs in white AT inflammation in obesity, and will also highlight the potential of miRNAs as targets for therapeutic intervention in MS as well as the challenges lying in miRNA-targeting therapeutics.
