The role of the host—Neutrophil biology
Periodontology 2000, EarlyView., 2023 Abstract Neutrophilic polymorphonuclear leukocytes (neutrophils) are myeloid cells packed with lysosomal granules (hence also called granulocytes) that contain a formidable antimicrobial arsenal. They are terminally differentiated cells that play a critical role in acute and chronic inflammation, as well as in the resolution of inflammation and wound ...

Staphylococcus aureus Leukotoxin GH Promotes Inflammation [PDF]
The Journal of Infectious Diseases, 2012 Staphylococcus aureus produces numerous molecules that facilitate survival in the host. We recently identified a novel S. aureus leukotoxin (leukotoxin GH [LukGH]) using proteomics, but its role in virulence remains unclear. Here we investigated the role of LukGH in vivo.We tested cytotoxicity of LukGH toward polymorphonuclear leukocytes (PMNs) from ...

Severe Necrotizing Community-Acquired Pneumonia and Bilateral Empyema in an Immunocompetent Patient due to <i>Fusobacterium necrophorum</i>. [PDF]
Case Rep PulmonolNecrotizing pneumonia and empyema caused by Fusobacterium necrophorum are uncommon. The classical presentation of Lemierre′s syndrome, characterized by pharyngotonsillitis and internal jugular vein thrombosis, is not always observed, and incomplete and atypical variants can cause diagnostic uncertainty and delay in treatment.

Immunosuppressive properties of Actinobacillus actinomycetemcomitans leukotoxin [PDF]
Infection and Immunity, 1988 Actinobacillus actinomycetemcomitans produces a leukotoxin that kills human polymorphonuclear cells (PMNs) and monocytes but not lymphocytes. In this study, we examined A. actinomycetemcomitans leukotoxin for its ability to alter human peripheral blood lymphocyte (HPBL) responsiveness.

Periodontal Disease: A Contributing Factor to Adverse Outcome in Diabetes. [PDF]
J DiabetesABSTRACT Periodontal disease is a prevalent and chronic inflammatory condition increasingly recognized for its systemic implications beyond oral health. While traditionally confined to dentistry, recent evidence reveals strong associations between periodontitis and chronic systemic conditions such as cardiovascular disease, diabetes mellitus ...
