Abstract
Transforming growth factor (TGF)-β is a prototypic multifunctional cytokine whose broad modulatory mechanisms affect numerous biological functions both at the cell and organism levels. These include, but are not limited to, control of immune functions, embryogenesis, carcinogenesis, tissue responses to injury, cell proliferation, extracellular matrix (ECM) synthesis and degradation, and cell migration. The identification of Smad proteins, TGF-β receptor kinase substrates that translocate into the cell nucleus to act as transcription factors, has increased our understanding of the molecular mechanisms underlying TGF-β action. This introductory chapter will outline the current knowledge on how specific signals initiated by the TGF-β receptors are brought to the nucleus to regulate gene expression, with a specific emphasis on how such signaling relates to connective tissue remodeling, repair, and fibrosis.
