Roles of the chemokine system in development of obesity,insulin resistance,and cardiovascular disease

The escalating epidemic of obesity has increased the incidence of obesity-induced complications to historically high levels. adipose tissue is a dynamic energy depot,which stores energy and mobilizes it during nutrient deficiency. excess nutrient intake resulting in adipose tissue expansion triggers lipid release and aberrant adipokine,cytokine and chemokine production,and signaling that ultimately lead to adipose tissue inflammation,a hallmark of obesity. this low-grade chronic inflammation is thought to link obesity to insulin resistance and the associated comorbidities of metabolic syndrome such as dyslipidemia and hypertension,which increase risk of type 2 diabetes and cardiovascular disease. in this review,we focus on and discuss members of the chemokine system for which there is clear evidence of participation in the development of obesity and obesity-induced pathologies. © 2014 longbiao yao et al.
