Adipose tissue can secrete various bioactive circulating mediators referred as ‘adipokines’, like adiponectin, leptin, chemerin, resistin, visfatin and vaspin, in addition to cytokines and chemokines such as tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6), IL-1β, and monocyte chemoattractant protein-1.136 Dysregulation of these adipokines has been implicated in the onset of obesity, IR, type 2 diabetes, cardiovascular disease, hypertension and metabolic syndromes.137. This evidence concerns the gene TNF and metabolic syndrome.
