چکیده
|
No evidence for the role of protease-activated receptor-2 (par2) in human periodontal disease has been demonstrated so far. thus,we sought to investigate the expression of par2 mrna in chronic periodontitis,and to examine whether its expression is related to the presence of par2 potential activators. microbiological and gingival crevicular fluid samples were collected from individuals with chronic periodontitis and control individuals,and the presence of neutrophil serine proteinase 3 (p3) and porphyromonas gingivalis was evaluated. par2 mrna expression was higher (p < 0.001) in those with chronic periodontitis compared with control individuals,and it was statistically decreased (p = 0.0006) after periodontal treatment. furthermore,those with chronic periodontitis presented higher (p < 0.05) levels of il-1±,il-6,il-8,and tnf-±,total proteolytic activity,p. gingivalis prevalence,and p3mrna expression compared with control individuals. we conclude that par2 mrna expression and its potential activators are elevated in human chronic periodontitis,therefore suggesting that par2 may play a role in periodontal inflammation. © international & american associations for dental research.
