ObjectiveTo summarize the research advancement of peroxisome proliferator-activated receptor γ (PPARγ) agonists inhibiting transforming growth factor-β (TGF-β)-induced organ fibrosis. MethodsThe related literatures on PPARγ agonists inhibiting TGF-β-induced organ fibrosis were reviewed. ResultsTGF-β was a major fibrosispromoting cytokine, which could promote a variety of organ fibrosis. PPARγ agonists could effectively block TGFβ signal transduction, and then suppressed organ fibrosis well. ConclusionsThe main antifibrotic mechanism of PPARγ agonists is to inhibit TGF-β signal transduction. The studies on this mechanism will help promoting the clinical application of PPARγ agonists, and provide a new way of the treatment for organ fibrosis.
