RESUMO
Glucose and lipid metabolism is the most fundamental metabolic activity of higher organisms. This process is affected by both genetic polymorphisms and environmental factors. Excessive uptake and accumulation of lipids lead to obesity and disorder of glucose metabolic homeostasis characterized by insulin resistance and hyperglycemia, suggesting that the cross-regulation between lipid and glucose metabolism happens precisely at organ, cellular and molecular levels by known mechanisms. Adenine nucleotides and their metabolites have emerged as mediators in the mutual regulation of glucose and lipid metabolism. This review summarizes the roles of purinergic signaling induced by fatty acids in glucose metabolism and the development of type 2 diabetes.
