PPARs function as metabolic sensors that bind directly to a variety of natural fatty acids and oxidized fatty acid metabolites (eicosanoids), coupling fatty acid flux to the transcriptional regulation of lipid and glucose homeostasis genes.
Your body's PPAR receptors are naturally activated by the fatty acids you eat and metabolize. These receptors act as sensors, adjusting gene expression to manage lipid and glucose levels based on your dietary fat intake.
GoodSupportsHIGH confidence
Thus, the PPARs may function as generalized sensors of fatty acid levels, coupling fluxes in the levels of these fatty acids to the transcriptional regulation of genes involved in lipid and glucose homeostasis.
Why this rating
Strong evidence from binding assays and gene expression studies, though the exact in vivo ligand concentrations and specificity remain areas of active research.

- PPARγ agonists (glitazones) improve insulin sensitivity and lower glucose in type 2 diabetes by promoting fatty acid flux into adipose tissue, thereby reducing lipid interference with glucose utilization in muscle and liver.Strong
- PPARα agonists (fibrates) lower serum triglycerides and raise HDL cholesterol by directly binding to the PPARα receptor, thereby inducing genes involved in fatty acid oxidation and peroxisome proliferation.Good
