There’s no place like OM: subcellular sorting and secretion of PPAD in Porphyromonas gingivalis
Our present findings show for the first time that the virulence factor PPAD protects the oral pathogen P. gingivalis against neutrophil insults at three distinct levels, namely phagocytosis, NETosis and CAMP activity. This identifies PPAD as a major agent in the evasion of human innate immunity, a v...

Accessory fimbrial subunits and PPAD are necessary for TLR2 activation by Porphyromonas gingivalis
Porphyromonas gingivalis is an oral pathogen that promotes dysbiosis by quenching the bactericidal activity of the host immune system while maintaining chronic inflammation, leading to periodontitis. This involves the secretion of virulence factors such as P. gingivalis peptidyl arginine deiminase (...

Macrophage activation and invasion by Porphyromonas gingivalis is modulated by PPAD and accessory fimbriae subunits
Background: Porphyromonas gingivalis is a master manipulator of host immune responses in periodontium. Peptidyl arginine deiminase (PPAD), a recently described virulence factor of P. gingivalis, responsible for both host- and bacterium-derived proteins and peptides citrullination, also plays an impo...
