Although gingipains are the major virulence factor of the pathogen, their role in impairing apoptosis and immune cell function is not fully understood. To investigate the impact of gingipains on neutrophil viability and function, we conducted studies using murine HoxB8 neutrophils and primary human neutrophils infected with wild-type strains of\n                    <jats:italic>Porphyromonas gingivalis<\/jats:italic>\n                    (W83 and ATCC 33277), or a gingipains-null mutant with deleted gingipains encoding genes, or wild-type bacteria preincubated with specific gingipain inhibitors.

Importantly, experiments using primary human neutrophils and macrophages revealed that gingipains play a significant role in the disruption of immune cell functions via the induction of reactive oxygen species and inactivation of neutrophil elastase activity. Additionally, although gingipains played a role in modulating the IL-8-dependent inflammatory response of human neutrophils, they did not affect the expression levels of pro-inflammatory cytokines TNF-\u03b1 and IL-6.\n                  <\/jats:p>","DOI":"10.3389\/fcell.2025.1419651","type":"journal-article","created":{"date-parts":[[2025,1,28]],"date-time":"2025-01-28T01:44:54Z","timestamp":1738028694000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":6,"title":["Porphyromonas gingivalis affects neutrophil pro-inflammatory activities"],"prefix":"10.3389","volume":"13","author":[{"given":"Agnieszka","family":"Zimny","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alicja","family":"P\u0142onczy\u0144ska","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wiktor","family":"Jakubowski","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Natalia","family":"Zubrzycka","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jan","family":"Potempa","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maja","family":"Sochalska","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2025,1,28]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"726","DOI":"10.1902\/jop.2010.100508","article-title":"Refractory periodontitis population characterized by a hyperactive oral neutrophil phenotype","volume":"82","author":"Aboodi","year":"2011","journal-title":"J.
