Transforming growth factor-beta 1 is a costimulator for IgA production.

Abstract

Transforming growth factor-beta 1 (TGF-beta 1) belongs to a family of polypeptides involved in the regulation of cell growth and differentiation. We have examined the ability of TGF-beta 1 to regulate isotype specific Ig secretion by murine spleen B cells. TGF-beta 1, in the presence of rIL-2, induced a synergistic 10-fold or greater increase in IgA… (More)
