Porphyromonas gingivalis (Pg) is a significant periodontal pathogen; it is the only bacterium known to possess a peptidyl arginine deiminase (PAD) which generates a citrullinated peptide by posttranslational modification (citrullination) of protein bound arginine; the citrullinated peptide and anticyclic citrullinated peptide (anti-CCP) autoantibody are capable of breaking down self tolerance and lead to the development of autoimmune RA.
(7) Genomewide association studies have identified variants in potentially pathogenic genes in non-HLA regions, including PTPN22 (8) [protein tyrosine phosphatase, non-receptor type 22 (lymphoid)], the TRAF1-C5 locus [TRAF1 (TNF receptor-associated factor 1) to C5 (complement component 5)], PADI4 (peptidyl arginine deiminase, type IV), and STAT4 (signal transducer and activator of transcription 4).
This hypothesis is supported by expression of arcA, arcB, arcC, and arcD, genes predicted to encode an arginine deiminase, an ornithine carbamoyltransferase, a carbamate kinase, and an arginine/ornithine antiporter, respectively (Table 3).
