The effect of the dentifrice ingredient triclosan (2,4,4'-trichloro-2'-hydroxyldiphenyl ether) on the production of interleukin (IL)-1beta and IL-6 was studied in human gingival fibroblasts challenged with tumor necrosis factor alpha (TNFalpha) in vitro. When gingival fibroblasts were treated simultaneously with triclosan (0.25, 0.5 microg/ml) and TNFalpha (10 ng/ml), the stimulatory effect of TNFalpha on IL-1beta production was reduced by the agent. In situ hybridisation showed that the TNFalpha-induced expression of IL-1beta mRNA was significantly reduced by triclosan. Furthermore, when the cells were treated simultaneously with a known protein kinase C (PKC) activator, phorbol 12-myristate-13-acetate (PMA) and TNFalpha in the presence of triclosan (0.5 microg/ml), the agent reduced the production of IL-1beta. In contrast to its effect on IL-1beta, triclosan did not influence the mRNA expression or the production of IL-6 induced by TNFalpha. The finding that triclosan reduces the production of the inflammatory mediator IL-1beta in gingival fibroblasts further supports the view that triclosan exhibits an anti-inflammatory effect.
