Mucosa-Environment Interactions in the Pathogenesis of Rheumatoid Arthritis [PDF]
, 2019 Mucosal surfaces play a central role in the pathogenesis of rheumatoid arthritis (RA). Several risk factors, such as cigarette smoking, environmental pollution, and periodontitis interact with the host at the mucosal level, triggering immune system ...

Effects of Aggregatibacter actinomycetemcomitans leukotoxin on endothelial cells
Microbial Pathogenesis, 2013 Aggregatibacter actinomycetemcomitans is a human pathogen that produces leukotoxin (LtxA) as a major virulence factor. In this study the effect of LtxA on microvascular endothelial cell viability and phenotype was studied. High doses of single LtxA treatment (500 ng/ml to 5 μg/ml) significantly and irreversibly decreased cell proliferation and induced ...

International Journal of Food Science, Volume 2026, Issue 1, 2026.Staphylococcus aureus is a leading cause of foodborne diarrhea, primarily due to staphylococcal enterotoxins (SEs). This study employed whole‐genome sequencing to characterize 106 S. aureus isolates from diarrheal patients in East China (2019–2024). We identified 23 sequence types, with ST398 (22.6%) and ST5 (7.5%) among the most prevalent.

Lipopolysaccharides mediate leukotoxin secretion in Aggregatibacter actinomycetemcomitans [PDF]
Molecular Oral Microbiology, 2011 SummaryWe previously reported that lipopolysaccharide (LPS) ‐related sugars are associated with the glycosylation of the collagen adhesin EmaA, a virulence determinant of Aggregatibacter actinomycetemcomitans. In this study, the role of LPS in the secretion of other virulence factors was investigated.

The FASEB Journal, Volume 39, Issue 23, 15 December 2025.Salivary multiomics from healthy, PD, RA, and PD‐RA cohorts identified PD−/RA‐linked microbial and metabolic signatures. We then transplanted salivary microbiota from a PD donor or a healthy donor into collagen‐induced arthritis mice. PD microbiota colonized the gut, reshaped communities, weakened epithelial tight junctions, and provoked systemic ...

Microbial Community Composition Impacts Pathogen Iron Availability during Polymicrobial Infection [PDF]
, 2016 Iron is an essential nutrient for bacterial pathogenesis, but in the host, iron is tightly sequestered, limiting its availability for bacterial growth. Although this is an important arm of host immunity, most studies examine how bacteria respond to iron ...
