Tumour necrosis factors modulate the affinity state of the leukotriene B4 receptor on human neutrophils

J Brom et al. Immunology. 1988 Dec.

Abstract

Pre-incubation of human polymorphonuclear granulocytes with recombinant human tumour necrosis factors (TNF) revealed a time- and dose-dependent reduction of the expression of leukotriene B4-receptor sites. Analysis of the binding data by Scatchard plots showed a shift from a heterologous receptor population (indicating high- and low-affinity subsets) to a homologous population. From the results it is considered that TNF can influence host defence through the modulation of leukotriene B4 receptor affinity.
