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 ...

Oral and Pancreatobiliary Microbiota in Cancer: A Systematic Review of Compositional Alterations and Their Clinical Implications

Journal of Oral Pathology &Medicine, EarlyView.
ABSTRACT Background Associations between microbial dysbiosis and malignancies of the pancreatobiliary system have been described in recent studies. As a result of the limited number of studies that have been done specifically on the malignancies of the biliary tract, information regarding oral, biliary and tumour‐related microbial alterations was ...

The Role of Viruses in the Pathogenesis of Periodontitis

Journal of Periodontal Research, EarlyView.
This narrative review aimed to summarize current evidence on the presence and potential pathogenic role of viruses in periodontitis. Design: Narrative Review; Population: Patients with periodontitis; Exposure: Detection of viruses in oral samples (biopsies, saliva, gingival crevicular fluid, subgingival plaque, blood); Outcome: Viral prevalence, load ...

Autoimmunity and Periodontitis

Journal of Periodontal Research, EarlyView.
In a microbe‐driven inflammatory environment, peptidyl‐arginine deiminase (PAD) enzymes from neutrophils and Porphyromonas gingivalis citrullinate both microbial and self‐antigens. B cell presentation of citrullinated or self‐mimicking epitopes activates T cells that assist B cells in antibody isotype switching, affinity maturation, epitope spreading ...

Localized Periodontitis in Young Individuals: Aggregatibacter JP2 Clone, Immunological Dysfunctions and Other Stories

Journal of Periodontal Research, EarlyView.
This review describes the features of grade C molar‐incisor pattern periodontitis and discusses the role of A. actinomycetemcomitans in its pathogenesis and why molars and incisors are preferably affected. Possible future studies on this aggressive disease in primary and permanent dentition and emerging omics techniques for diagnosis and management are

Bdellovibrio bacteriovorus Attacks Aggregatibacter actinomycetemcomitans

Journal of Dental Research, 2009
Periodontitis is a polymicrobial infectious disease primarily associated with Gram-negative periodontopathogens. Bdellovibrio and like organisms are predatory bacteria that feed on Gram-negative bacteria. This study investigated whether predatory bacteria can attack Aggregatibacter actinomycetemcomitans. Therefore, A.
