The content and skin distribution of the transforming growth factor β1 (TGF-β1), transforming growth factor-β receptor type I receptor (TGF-βRI) and platelet-derived growth factor receptor a (PDGFR-α), which are key fibrosis mediators, were examined in ten patients with localized scleroderma and ten healthy volunteers by using the immunohistochemistry method. A reduced derma concentration of TGF-β1+ cells (р = 0.007) and increased amount of TGF-βRI+ (р = 0.001) and PDGFR-α+ (р < 0.001) cells was discovered in the patients vs. the control group. Te reduced amount of TGF-β1 in the affected loci can be apparently explained by its reduced production by cells taking part in the immune inflammation. Increased expression of TGF-βRI receptors (р = 0.001) and PDGFR-α in the foci of localized scleroderma confirms their important role in the pathogenesis of the disease and activation of the fibrosis process in the skin.
