Periodontitis is an irreversible, chronic inflammatory, infectious disease of the oral cavity that affects approximately half of all adults 30 years or older in the USA. The oral cavity is under high immune surveillance because of its constant exposure to microbes in the environment. The primary immune cell responsible for this surveillance is the neutrophil. Pathogens associated with periodontitis possess virulence factors and have evolved strategies to evade neutrophil antimicrobial responses to survive. One such pathogen is Filifactor alocis, whose presence is associated with the progression of periodontitis. F. alocis manipulates several neutrophil antimicrobial functional responses to avoid killing, an …

Almost 50% of adult Americans suffer from periodontitis which is a bacterially induced inflammation of the tissue that surround and support the tooth. The accumulation of neutrophils, a critical cell component of the innate immune system, in the gingival crevice contributes to tissue damage. Filifactor alocis is a newly appreciated pathogen present in oral biofilms at periodontal disease sites. Studying the interactions between neutrophils and F. alocis will provide valuable information for delineating the role of this bacterium in periodontal disease and enhance our understanding of bacterial strategies to evade leukocytes’ antimicrobial mechanisms. The hypothesis that F. alocis modulates human …
