PG - 128-32 AB - Two cytokines important in the regulation of B-cell function are tumor necrosis factor-alpha (TNF-alpha) and interleukin-6 (IL-6). They act at different steps in B-cell differentiation and can be produced by the B cells themselves upon appropriate stimulation. Crosslinking of surface Ig and signaling through CD22 or CD40 lead to increased secretion of both cytokines. Neutralization of TNF-alpha or IL-6 biologic activity in B-cell cultures results in a significant reduction in B-cell proliferation and Ig secretion. Increased production of these cytokines is found in several diseases associated with aberrant B-cell function. This review will focus on the role of TNF-alpha and IL-6 in normal and pathophysiological conditions of B-cell function.
