| Research Abstract |
In human gingival cells, Sa3 cells, LPS induced the expression of IL-6 and TNF・in dependent of NF-・B but not PKR. LPS also increased the binding of PACT to PKR through NF-・B pathway, resulting in the phosphorylation of PKR. The inactivation of PKR activity caused the up-regulation of IL-6 mRNA expression in mouse osteoblastic cells, MC3T3-E1 cells. However, it still unclear whether LPS-induced pro-inflammatory cytokines are implicated in the regulation of PKR activation in Sa3 cells. These results suggest that PKR is activated by binding to PACT through NF-・B pathway in periodontitis. On the other hand, we compared the value of clinical parameters of periodontal status, the value of anti-HSP60 salivary IgA and the existence of periodontopathgenic bacteria in saliva between the rheumatoid group (n=7) and the control group (n=7). No significant difference is observed between two groups except for the existence of Campylobacter rectus. These results indicated that the measurement of the Campylobacter rectus in saliva might be the important criteria under the intervention of professional oral health care.
