PPARG and scleroderma: We are struck by the parallels between reduced adiponectin and disappearance of fat tissue in liver fibrosis on the one hand, where quiescent fat-strong hepatic stellate cells transition into fibrogenic myofibroblasts with down-regulation of PPAR-γ, and loss of subcutaneous adipose tissue associated with dermal fibrosis in patients with scleroderma.
