It is now recognized that the WAT (white adipose tissue) produces a variety of bioactive peptides, collectively termed "adipokines". Alteration of WAT mass in obesity or lipoatrophy affects the production of most adipose secreted factors. Since both conditions are associated with insulin resistance, the idea has emerged that certain adipokines might influence insulin action. Among these, tumour necrosis factor alpha, interleukin-6 and resistin are increased in the obese state and interfere negatively with insulin-mediated processes. Conversely, leptin and adiponectin exert an insulin-sensitizing effect, at least in part by favouring tissue fatty-acid oxidation through AMP-activated kinase activation. Obesity-induced insulin resistance has been linked to leptin resistance and decreased plasma adiponectin, while administration of leptin and adiponectin normalizes plasma levels in lipoatrophic mice and reverses insulin resistance. Thiazolidinedione anti-diabetic agents increase endogenous adiponectin production in rodents and humans, supporting the idea that drugs targeting adipokines might represent a new therapeutic approach to sensitize peripheral tissues to insulin.

Thiazolidinedione (TZD) compounds enhance insulin sensitivity and attenuate inflammation. The effect of the TZD compound, rosiglitazone (RSG) on both actions was evaluated in two groups of insulin-resistant subjects with minimal elevations of fasting plasma glucose (PG) concentration: group A (n=15, PG < 7.0 mmol/L) and group B (n=14, PG 7.0-8.3 mmol/L). Insulin action, quantified by the insulin suppression test, improved after three months of treatment in both groups, and concentrations of C-reactive protein, plasminogen activator inhibitor-1 and Eselectin all fell. Significant decreases in L-selectin and P-selectin were confined to group B, and concentrations of interleukin-6, intercellular adhesion molecule-1 and vascular cellular adhesion molecule-1 did not fall in either group. Significant relationships were not discerned between enhanced insulin sensitivity and related variables and decreases in inflammatory/vascular markers, suggesting that RSG-induced changes in the latter variables in insulin-resistant individuals might be at least partly independent of the effects of the drug on insulin action.
