Abstract
Chemokine and chemokine receptor expression in gingival tissues plays a central role in periodontal disease during aging. In the present study, we explored the modulation of chemokines and chemokine receptors expression in aging rat gingival tissues. In the 24-month-old (Old) rat gingival tissues, RANTES and CCR5 mRNA and protein levels were 2–4 fold increased over those of the 6-month-old (Young) rats. The Old rats had considerable enhancement of all three of the studied MAPK activities: extracellular signal regulated kinase (ERK), c-Jun N-terminal kinase (JNK), and p38 MAPK. These results suggest that age-related increases in RANTES and CCR5 expression are associated with increased IκBα, nuclear NF-κB, and MAPK activity in gingival tissues.
