Detection of a 640-bp deletion in the Aggregatibacter actinomycetemcomitans leukotoxin promoter region in isolates from an adolescent of Ethiopian origin

open access: yesJournal of Oral Microbiology, 2015
The expression of the leukotoxin of Aggregatibacter actinomycetemcomitans is regulated by the leukotoxin promoter. A 530-bp deletion or an 886-bp insertion sequence (IS) element in this region has earlier been described in highly leukotoxic isolates ...

The aggregatibacter actinomycetemcomitans heat shock protein GroEL interacts directly with human peripheral blood T cells [PDF]

open access: yes, 2016
Heat shock family protein GroEL of Aggregatibacter actinomycetemcomitans (Aa) has antigenic properties. We previously demonstrated that A. actinomycetemcomitans GroEL-like protein affects human CD4 T cells by converting them into IL-10 and IFNg double ...

Increased leukotoxin production: Characterization of 100 base pairs within the 530 base pair leukotoxin promoter region of Aggregatibacter actinomycetemcomitans

open access: yesScientific Reports, 2017
Aggregatibacter actinomycetemcomitans leukotoxin (LtxA) is a major virulence factor that kills leukocytes permitting it’s escape from host immune surveillance. A. actinomycetemcomitans strains can produce high or low levels of toxin.

The role of Aggregatibacter actinomycetemcomitans and its leukotoxin in periodontitis

open access: yesJournal of Oral Microbiology, 2017
Aggregatibacter actinomycetemcomitans is a Gram-negative periodontitis-associated bacterium that expresses a toxin that selectively affects leukocytes. Leukotoxin is encoded by an operon belonging to the core genome of this bacterial species.

Interactions of extracts from selected chewing stick sources with Aggregatibacter actinomycetemcomitans

open access: yesBMC Research Notes, 2012
Background Aggregatibacter actinomycetemcomitans produces a leukotoxin that activates a pro-inflammatory death of human monocytes/macrophages. A specific clone of this bacterium (JP2) has a 530-base pair deletion in the leukotoxin promoter gene and ...
