Abstract
Transforming growth factor-beta (TGF-beta), a multifunctional polypeptide is produced by a wide variety of cells and regulates a broad array of physiological and pathological functions. TGF-beta appears to play a central role in pulmonary fibrosis and may contribute to tumor-associated immunosuppression. Alveolar macrophages are a rich source of TGF-beta and are intimately involved in lung inflammation. We therefore chose to study TGF-beta regulation in murine alveolar macrophages as well as an immortalized peritoneal macrophage cell line (IC-21). Murine macrophages were incubated with cytokines to evaluate their role in regulating TGF-beta mRNA expression. We conclude that IFN-alpha downregulates TGF-beta mRNA expression in murine macrophages.Entities:
