title: Taurine chloramine modulates cytokine production by human peripheral blood mononuclear cells.
abstract: The effect of taurine (Tau) and taurine chloramine (Tau-Cl) on the production of TNF- alpha, IL-1 beta, and IL-6 by peripheral blood mononuclear cells of healthy volunteers was examined. Cells were stimulated with bacterial lipopolysaccharide (LPS) in the presence of either Tau or Tau-Cl. After 24 h culture the cytokine concentrations were measured in both culture supernatants (secreted) and cell lysates (cell-associated) using ELISA. In LPS-stimulated cells Tau-Cl inhibited both the secreted and cell-associated IL-1 beta and IL-6, while exerted dual effect on TNF- alpha production: raising it slightly at low and reducing at higher concentration. By contrast, Tau had no significant effect on the cytokine production. These results indicate that Tau-Cl modulates synthesis of pro-inflammatory cytokines, and therefore it may play a role in the initiation and propagation of immune response.
