Antagonistic Regulation of Type I Collagen Gene Expression by Interferon-γ and Transforming Growth Factor-β
1 Apr 2001
Abstract excerpt
Among the extracellular signals that modulate the synthesis of collagen, transforming growth factor-beta (TGF-beta) and interferon-gamma (IFN-gamma) are preeminent. These two cytokines exert antagonistic effects on fibroblasts, and play important roles in the physiologic regulation of extracellular matrix turnover. We have shown previously that in normal skin fibroblasts, TGF-beta positively regulates alpha2(I)...
