OBJECTIVE: The objective of the present study was to determine the effects of concurrent LPS and cytokine priming, reflective of the in vivo milieu, on macrophage production of key periodontitis associated cytokines TNF, IL-1β and IL-6. DESIGN: THP-1 cells were pre-treated with combinations of Porphyromonas gingivalis and Escherichia coli lipopolysaccharide (LPS), concurrently with polarising cytokines IFNγ and IL-4, or PMA as a non-polarised control. Production of key periodontitis associated cytokines in response to subsequent LPS challenge were measured by enzyme - linked immunosorbent assay. RESULTS: Compared with cells incubated with IFNγ or IL-4 alone in the "polarisation" phase, macrophages that were incubated with LPS during the first 24h displayed a down-regulation of TNF and IL-1β production upon secondary LPS treatment in the "activation" phase. In all three macrophage populations (M0, M1 and M2), pre-treatment with P. gingivalis LPS during the polarisation process led to a significant decrease in TNF production in response to subsequent activation by LPS (p=0.007, p=0.002 and p=0.004, respectively). Pre-treatment with E. coli LPS also led to a significant down-regulation in TNF production in all three macrophage populations (p<0.001). Furthermore, the presence of E. coli LPS during polarisation also led to the down-regulation of IL-1β in the M1 population (p<0.001), whereas there was no measurable effect on IL-1β production in M0 or M2 macrophages. There was no significant effect on IL-6 production. CONCLUSIONS: Macrophages become refractory to further LPS challenge, whereby production of key periodontitis associated cytokines TNF and IL-1β is reduced after exposure to LPS during the polarisation phase, even in the presence of inflammatory polarising cytokines. This diminished cytokine response may lead to the reduced ability to clear infection and transition to chronic inflammation seen in periodontitis. | |
