Smad3 and Smad4 mediate transforming growth factor-β1-induced IgA expression in murine B lymphocytes
1 Jun 2001
Abstract excerpt
Transforming growth factor (TGF)-beta1 is well established as a critical IgA isotype switching factor and Smad molecules have been reported to act as transducers and transcriptional factors in the expression of TGF-beta1-targeted genes. We examined the involvement of Smad proteins in TGF-beta1-induced IgA expression. First, we found that TGF-beta1 significantly increases endogenous germ-line (GL) alpha...
