Figure 5.

Frequencies of cytokine‐producing cells CD8⁺ and γδ T cells in peripheral blood mononuclear cells (PBMC) from healthy controls and patients with periodontal disease. PBMC were isolated from peripheral blood from patients with chronic periodontitis (CP, n = 15) or aggressive periodontitis (AP, n = 15) as well as periodontally healthy controls (HC, n = 13). (a,b) Representative dot‐plots and cumulative data for the frequencies of IL‐17⁺, IFN‐γ⁺ and TNF‐α⁺ cells within CD8⁺ T cells (a) or γδ T cells (b). Each symbol represents an individual donor. Lines show the mean with standard error of the mean (s.e.m.). Log‐transformed data were analysed by one‐way analysis of variance with Bonferroni’s multiple comparison test.
