PPAR delta as a therapeutic target in metabolic disease

PPAR delta is the only member in the PPAR subfamily of nuclear receptors that is not a target of current drugs. Animal studies demonstrate PPAR delta activation exerts many favorable effects, including reducing weight gain, increasing skeletal muscle metabolic rate and endurance, improving insulin sensitivity and cardiovascular function and suppressing atherogenic inflammation. These activities stem largely from the ability of PPAR delta to control energy balance, reduce fat burden and protect against lipotoxicity caused by ectopic lipid deposition. Therefore, PPAR delta represents a novel therapeutic target and the development of PPAR delta gonists/modulators may be useful for treating the whole spectrum of metabolic syndrome.
