Abstract

It is recognized that abdominal obesity is accompanied by a chronic low-grade inflammation that is involved in the pathogenesis of insulin resistance and type 2 diabetes. Metabolic syndrome and type 2 diabetes are associated with an abnormal production of pro-inflammatory cytokines, an increased level of acute-phase proteins and an activation of inflammatory signalling pathways. These pro-inflammatory cytokines, mainly produced by adipose tissue macrophages, are involved in development of obesity-associated insulin resistance and in the progression from obesity to type 2 diabetes. Particularly, the interleukin-1 beta may play a key role through the activation of the NLRP3 inflammasome. Adipose tissue topography, more than the total amount of fat, may play an important pathogenic role. Indeed, the presence of metabolic abnormalities in obesity is associated with a deleterious immunological and inflammatory profile of visceral adipose tissue and with an increased activation of the NLRP3 inflammasome in macrophages infiltrating visceral adipose tissue. Targeting inflammation, especially NLRP3 inflammasome, may offer potential novel therapeutic perspectives in the prevention and treatment of type 2 diabetes.
