PPARγ, 10 years later

It is now over 10 years since the discovery of peroxisome proliferator activated receptor γ (PPARγ) and its unique role in adipogenesis. The subsequent identification of PPARγ as the target of insulin sensitizing drugs certified this ligand-regulated transcription factor as an exciting link between adipocyte biology and peripheral insulin resistance. Here, I summarize the great progress that has been made over the past decade in elucidating the biology of PPARγ and its role in adipogenesis and glucose metabolism. Prospects for future research leading to new therapies for obesity and diabetes are also discussed.
