Abstract
dc.description.abstract
Background: Interleukin-21 (IL-21) controls the differentiation of T-helper Th17 cells and induces the production of IL-17
in this T-cell subtype. The aim of this study is to determine the
relative expression of IL-21 in gingival tissues of chronic periodontitis patients and correlate/associate this expression with
proinflammatory cytokines and clinical parameters of disease.
Methods: Samples of gingival biopsies were collected from
chronic periodontitis patients (n = 10) and controls (n = 8).
The mRNA expressions of IL-21, IL-1b, IL-6, IL-17, IL-23,
IL-10, and transforming growth factor-b1 (TGF-b1) were quantified using real-time reverse transcription-polymerase chain
reaction. IL-21 levels were compared between chronic periodontitis and healthy gingival tissues and correlated with cytokine and clinical parameters of tissue destruction.
Results: A significant overexpression of IL-21, IL-1b, IL-6,
IL-17, and IL-23p19 was detected in periodontal disease–
affected tissues compared to healthy gingival tissues. IL-10
and TGF-b1 were, however, downregulated in periodontal
lesions. IL-21 yielded significant positive correlations with probing depth, clinical attachment level, IL-1b, and IL-6. In addition,
IL-21 was negatively correlated with IL-10 and TGF-b1.
Conclusions: IL-21 was overexpressed in chronic periodontitis gingival tissues and correlated with clinical parameters
of periodontal destruction and with proinflammatory cytokines. Therefore, IL-21 might play a role in the tissue destruction
that characterizes chronic periodontal disease. J Periodontol
