P. gingivalis targets a wide range of fibroblast-derived inflammatory mediators. Fibroblasts (50,000 cells/well) were stimulated with 50 ng/ml TNF-α for 6 h before the cells were treated with viable, or heat-killed P. gingivalis (MOI:1000) for 24 h. The used cytokine array renders possible detection of the cytokines and chemokines specified in Table 1. Cytokine and chemokine levels were determined according to manufacturer’s instructions (A). Treatment with viable P. gingivalis resulted in degradation of all inflammatory mediators except TNF-α and Serpin-1 (B).
