Transforming growth factor-?1 in plaque morphea.


ABSTRACT: INTRODUCTION:Morphea (localized scleroderma) is a rare cutaneous disease characterized by skin fibrosis of unknown pathogenesis. Transforming growth factor-? (TGF-?) is a potent profibrotic factor. The role of TGF-? in morphea remains unclear. AIM:The goal of this study was to estimate the expression level of TGF-?1 in skin and peripheral blood mononuclear cells as well as the plasma levels of TGF-?1 in plaque morphea (MEP). MATERIAL AND METHODS:The study involved 20 MEP patients. Three control groups were involved: 1 - plasma: 36 healthy volunteers; 2 - PBMC: 47 healthy volunteers; 3 - skin biopsies: 13 samples collected during mastectomy (breast cancer was not skin involved). The analysis of TGF-?1 plasma levels was performed with the use an adequate ELISA kit, while real-time polymerase chain reaction was employed for the expression of TGF-?1 in peripheral blood mononuclear cells (PBMC) and skin. RESULTS:In our study we have not detected differences in TGF-? 1 expression in PBMC, skin, nor in plasma levels of TGF-?1 between MEP patients and healthy controls, regardless of disease activity and its duration. CONCLUSIONS:The results of our study contradict the claim of the substantial role of TGF-?1 in the most common morphea subtype - MEP.
