Summary
This study investigated CD26 receptor expression in periodontal disease. Results indicate no significant difference in CD26 expression between sites with and without clinical attachment loss, suggesting Th1 cell impairment is not directly linked to periodontal attachment loss.
Area of Science:
- Immunology
- Periodontology
- Cell Biology
Background:
- Chronic inflammatory periodontal disease (CIPD) involves complex immunological mechanisms.
- Human CD4(+) lymphocytes exhibit diverse cytokine production profiles.
- CD26, a glycoprotein, marks Th1-like cytokine development.
Purpose of the Study:
- To compare the immuno-expression of the CD26 receptor in periodontal sites with and without clinical attachment loss (CAL).
Main Methods:
- Immunohistochemical identification of the CD26 receptor using the MIB-DS2/7 antibody.
- Biopsies were taken from ten periodontal sites with CAL and nine sites without CAL from six patients with different forms of periodontitis.
Main Results:
- The percentage of CD26-positive cells in periodontal sites with CAL was not significantly different compared to sites without CAL.
- No statistically significant difference was observed in CD26 receptor expression between the two groups.
Conclusions:
- Th1 cell impairment may not be directly implicated in the pathogenesis of periodontal attachment loss.
- The role of CD26 expression in the context of periodontal disease progression requires further investigation.
