Fig. 6From: Increased citrullination and expression of peptidylarginine deiminases independently of P. gingivalis and A. actinomycetemcomitans in gingival tissue of patients with periodontitisDetection of citrullinated proteins, P. gingivalis and leukotoxins of M. haemolytica and A. actinomycetemcomitans in gingival biopsies from patients with periodontitis and RA. Representative immunohistochemistry images of gingival biopsies (n = 4), stained for citrullinated proteins, P. gingivalis, M. haemolytica LktA and A. actinomycetemcomitans LtxA in gingival tissue samples are shown.
