[Peroxisome proliferator activated receptors PPARs: their role in carbohydrate and lipid metabolism].
Peroxisome proliferator activated receptors (PPAR) belong to a family of nuclear receptors broadly distributed in the organism. Their pleiotropic role has been recently proved as well as their pathogenic significance in diabetes, obesity, cell cycle controlling, carcinogenesis, inflammation and atherosclerosis. The three types of PPAR identified until today have different tissue localization. PPARgamma, primarily identified in macrophages and adipocytes, play an important role in the expression of proteins essential for lipid metabolism and adipogenesis. PPARalpha are localized predominantly in hepatocytes and have also an important role in lipid metabolism. PPAR are though to be lipid sensors in organism. Carbohydrate metabolism is also under the control of PPAR and their exogenous ligands, (ie: thiasolidinediones), are important antidiabetic drugs.
