ABSTRACT
PURPOSE:
Interleukin (IL)-8 is one of pro-inflammatory cytokines. Reactive oxygen species (ROS) are reduced metabolites of O2. Aggregatibacter actinomycetemcomitans is one of representative periodontopathogens. To investigate the role of A. actinomycetemcomitans in IL-8 expression of periodontal ligament (PDL) cells, we estimated the production of IL-8 and ROS in A. actinomycetemcomitans treated PDL cells.METHODS:
The IL-8 production was determined by enzyme-linked immunosorbent assay. The ROS production was estimated using H2DCFDA and FACS.RESULTS:
A. actinomycetemcomitans increased the production of IL-8 and ROS at 10, 100, and 500 multiplicity of infection. N-cetylcysteine, an antioxidant of ROS, down-regulated the production of IL-8 induced by A. actinomycetemcomitans.CONCLUSION:
These results suggest that A. actinomycetemcomitans induces IL-8 production and ROS may act as a mediator in this process.
