Peroxisome proliferator-activated receptors (PPARs) α, δ, γ are ligand-activated nuclear transcription factors involved in the regulation of energy homeostasis as well as insulin sensitivity and glucose metabolism. Pharmacologies of PPARδ receptor agonists, though relatively obscure, have recently been reported to elevate high-density lipoprotein (HDL) cholesterol and lower plasma triglyceride (TG) levels in obese insulin resistant rhesus monkeys.
