The heavy metal lead modulates the expression of both TNF-alpha and TNF-alpha receptors in lipopolysaccharide-activated human peripheral blood mononuclear cells.

Abstract:

:It has been shown that lead (Pb) potentiates lipopolysaccharide (LPS) lethality in animals by increasing the secretion and uptake or reactivity of tumor necrosis factor-alpha (TNF-alpha). Herein we report that PbCl2 increased TNF-alpha secretion from LPS-treated human peripheral blood mononuclear cells (PBMC) in a concentration- and time-dependent manner. PbCl2 also increased total cellular TNF-alpha levels but had no effect on the steady-state levels of TNF-alpha mRNA. PbCl2 decreased membrane-associated TNF-alpha (mTNF-alpha) on LPS-treated monocytes, whereas PbCl2 increased TNF-alpha receptor (TNF-R) p55 surface expression, and had no effect on TNF-R p75 surface expression by LPS-treated monocytes. Overall, the results suggest that PbCl2 increases TNF-alpha expression by posttranscriptional mechanisms in human PBMC, and enhances the reactivity and uptake of TNF-alpha by increasing the surface expression of TNF-R p55.
