Cardiac Fibrosis in Proteotoxic Cardiac Disease is Dependent Upon Myofibroblast TGF -β Signaling.

Background Transforming growth factor beta ( TGF -β) is an important cytokine in mediating the cardiac fibrosis that often accompanies pathogenic cardiac remodeling. Cardiomyocyte-specific expression of a mutant αB-crystallin (Cry AB), which causes human desmin-related cardiomyopathy, results in significant cardiac fibrosis. During onset of fibrosis, fibroblasts are activated to the so-called myofibroblast state and TGF -β binding mediates an essential signaling pathway underlying this process.
