Demonstrates how transforming growth factor beta regulates B lymphocyte function, suggesting immunomodulatory effects.

The study aims to understand the regulatory role of transforming growth factor beta on B lymphocyte growth and differentiation.
B lymphocytes were exposed to varying concentrations of transforming growth factor beta in vitro.
Interaction effects were analyzed by measuring B cell proliferation and immunoglobulin secretion.
Northern blot analysis quantified TGF-beta mRNA levels in activated and unactivated B cells.
TGF-beta suppresses interleukin 2-dependent B cell proliferation and immunoglobulin secretion.
B lymphocytes increase TGF-beta mRNA and secretion upon activation, with a sixfold to sevenfold increase noted after stimulation.
The inhibition of immunoglobulin secretion by TGF-beta cannot be reversed by increasing interleukin 2 levels.

Kehrl et al. (1986) studied this question.
