Identification and characterization of the Pasteurella haemolytica leukotoxin [PDF]

open access: yesInfection and Immunity, 1987
The identification and chromatographic characterization of the leukotoxin of Pasteurella haemolytica is described. The toxin, which has an apparent native molecular weight of greater than 400,000 as judged by gel exclusion chromatography, has a 105-kilodalton (105K) polypeptide as its major protein component.

PtrA is required for coordinate regulation of gene expression during phosphate stress in a marine Synechococcus [PDF]

open access: yes, 2010
Previous microarray analyses have shown a key role for the two-component system PhoBR (SYNW0947, SYNW0948) in the regulation of P transport and metabolism in the marine cyanobacterium Synechococcus sp. WH8102. However, there is some evidence that another

Autoimmunity and Periodontitis

open access: yesJournal 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 ...

Pathogenicity of the highly leukotoxic JP2 clone of Aggregatibacter actinomycetemcomitans and its geographic dissemination and role in aggressive periodontitis

open access: yesJournal of Oral Microbiology, 2014
For decades, Aggregatibacter actinomycetemcomitans has been associated with aggressive forms of periodontitis in adolescents. In the middle of the 1990s, a specific JP2 clone of A.

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

open access: yesJournal 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

Aggregatibacter actinomycetemcomitans (Aa) Under the Radar: Myths and Misunderstandings of Aa and Its Role in Aggressive Periodontitis

open access: yesFrontiers in Immunology, 2019
Aggregatibacter actinomycetemcomitans (Aa) is a low-abundance Gram-negative oral pathobiont that is highly associated with a silent but aggressive orphan disease that results in periodontitis and tooth loss in adolescents of African heritage.
