Figure 1.

Frequencies of major immune cell populations 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) Representative gating strategy and (b) cumulative data showing the frequencies of cell populations within live‐gated single cells. 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 followed by Bonferroni’s multiple comparison test.
