New insights into insulin resistance pathophysiology: how it affects glucose and lipid metabolism

Insulin resistance is a metabolic state encountered in many physiological and physiopathological conditions. Its pivotal effect on glucose and lipid metabolism is increasingly recognised. Over the last few years, numerous molecular/intracellular pathways affected by this condition have been elucidated. The author reviews some recent findings underlying several major metabolic abnormalities. An overview of current and future therapeutics is also provided.
