title: [Effect of toll-like receptors (TLR) ligands on in vitro synthesis of proinflammatory cytokines by peripheral blood mononuclear cells from healthy persons and from patients with common variable immunodeficiency].
abstract: Production of citokines of tumor-necrosis factor (TNF)-alpha and interferon (IFN)-alpha by peripheral blood mononuclear cells (PBMC) from healthy men and from patients with common variable immunodeficiency (CVID) after stimulation with zymosan, lypopolysaccharides, flagellin and CpG, which are ligands of TLR 2/6, TLR 4, TLR 5, TLR 9 respectively, was studied in vitro. In healthy men production of TNF-alpha varied between individuals, whereas synthesis of IFN-alpha was similar. Spontaneous production of TNF-alpha by PBMC in patients with CVID was increased and accompanied by decrease in TNF-alpha production stimulated by each analyzed ligands except CpG. Observed changes in TLR-dependent TNF-alpha production can play important role in pathogenesis of CVID.
