Plasma RgpB, CPP3 and RPP3 levels. Mean plasma concentrations (AU/ml ± SE) of antibodies against a RgpB, b CPP3 and RPP3 in arthritis rats with and without periodontitis and healthy control animals at endpoint of the experimental period of 15 weeks. *P < 0.05 was considered statistically significant. PA rats with experimental periodontitis and PIA (n = 9), A rats with PIA without periodontitis (n = 12), Healthy control rats without induced arthritis or periodontitis (n = 4), RgpB arginine gingipain B, CPP3 citrullinated peptide derived from PPAD, RPP3 arginine-containing (uncitrullinated) PPAD peptide
