Adiponectin suppresses fibrotic responses. Ligands of PPAR-γ induce adiponectin which triggers autocrine or paracrine activation of AMP kinase. AMP kinase in turn blocks TGF-β/Smad signaling and consequent stimulation of profibrotic gene expression. PPAR-γ, peroxisome proliferator activated receptor gamma; TGF-β, transforming growth factor-β.
