Fig. 1From: Increased citrullination and expression of peptidylarginine deiminases independently of P. gingivalis and A. actinomycetemcomitans in gingival tissue of patients with periodontitisEvaluation of the gingival tissue inflammation in the patients with and without periodontitis. a Representative immunohistochemical staining of CD3-positive lymphocytes in gingival tissue samples obtained from patients with periodontitis and periodontally healthy controls (non-periodontitis). Magnification ×100 and ×2.5 zoom-in on the area of interest (scale bars 100 μm). b and c graphs show mean of b positive cell scores of inflammation (± SD) and c CD3-positive lymphocytes in tissue sections obtained from patients with periodontitis (n = 15) and non-periodontitis subjects (n = 15).
