Interleukin 4 induces selective production of interleukin 6 from normal human B lymphocytes

In this paper we have shown that extensively purified human B lymphocytes respond to IL-4 treatment with a marked production of IL-6. Addition of anti-mu potentiated the effect of IL-4 on IL-6 production. Other cytokines tested like TNF-alpha and-beta, IFN-gamma, IL-1, IL-2, and IL-5 did not induce IL-6 secretion when given to resting B cells. Although B cells generally also produced TNF-alpha ...

Human recombinant interleukin 4 induces Fc epsilon receptors (CD23) on normal human B lymphocytes

Human rIL-4 is able to induce the expression of low-affinity receptors for IgE (Fc epsilon RL/CD23) on resting B lymphocytes, as determined by the binding of either the anti Fc epsilon RL/CD23-specific mAb 25 or IgE. Stimulation of B cells with insolubilized anti-IgM antibody increases the number of cells expressing Fc epsilon RL/CD23 upon culturing with IL-4 and enhances the level of Fc epsilo...

Interleukin-1 induces interleukin-6 production in peripheral blood monocytes.

Interleukin-6 (IL-6), a multifunctional cytokine produced in monocytes, fibroblasts, endothelial cells, and keratinocytes, is induced by a variety of stimulating signals, including lipopolysaccharide (LPS), poly (I), poly (C), IL-1, tumor necrosis factor (TNF), and platelet-derived growth factor. Some of these signals induce IL-6 effectively only in one cell type, and this selectivity of induct...

Interleukin-6 and interleukin-6 receptor secretion by chronic lymphatic leukaemia and normal B lymphocytes: effect of PMA and PWM

Interleukin-6 (IL-6) and soluble interleukin-6 receptor (sIL-6R) were detected in supernatants of cultures of B chronic lymphatic leukaemia (CLL) lymphocytes. Phorbol-12-myristate 13 acetate (PMA) caused a decrease in the levels of IL-6 in 14 out of 16 cultures and an increase in levels of sIL6R in all 15 cases. The effect of pokeweed mitogen (PWM) was variable and not significant. The levels o...

The interleukin-12 and interleukin-12 receptor system in normal and transformed human B lymphocytes.

BACKGROUND AND OBJECTIVES Interleukin-12 (IL-12) is a heterodimeric cytokine that induces interferon-g (IFN-g) production by natural killer and T-lymphocytes. IL-12 also activates human B-cells through the IL-12 receptor (IL-12R) complex. Here we review the expression and function of IL-12 and IL-12R in human B-cells and in their malignant counterparts. EVIDENCE AND INFORMATION SOURCES The in...
