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

Periodontal Medicine Rewired: Mechanisms Linking Periodontitis to Systemic Diseases
Journal of Periodontal Research, EarlyView.This review reorganizes decades of research in periodontal medicine into a multi‐dimensional framework, illustrating how periodontitis influences systemic health through at least seven interconnected mechanisms. ABSTRACT Periodontitis is now recognized not merely as a localized oral condition but as a systemic disease linked to over 70 communicable and

Periodontitis and Rheumatoid Arthritis—Mechanistic Evidence
Journal of Periodontal Research, EarlyView.Periodontitis and rheumatoid arthritis are linked via the two‐hit model whereby early periodontal inflammation can lead to autoantibody production capable of interacting with inflamed synovial tissues. Subsequent systemic inflammation can exacerbate the periodontal inflammatory response and bacterial dysbiosis leading to further autoantibody production

Pathogens, 2022 Carriers of highly leukotoxic genotypes of Aggregatibacter actinomycetemcomitans are at high risk for rapid degradation of tooth-supporting tissues. The leukotoxin (LtxA) expressed by this bacterium induces a rapid pro-inflammatory response in leukocytes

Receptor-Based Peptides for Inhibition of Leukotoxin Activity [PDF]
ACS Infectious Diseases, 2018 The Gram-negative bacterium Aggregatibacter actinomycetemcomitans, commonly associated with localized aggressive periodontitis (LAP), secretes an RTX (repeats-in-toxin) protein leukotoxin (LtxA) that targets human white blood cells, an interaction that is driven by its recognition of the lymphocyte function-associated antigen-1 (LFA-1) integrin.

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 ...

Periodontitis and rheumatoid arthritis—Global efforts to untangle two complex diseases
Periodontology 2000, EarlyView.Abstract Understanding the impact of oral health on rheumatoid arthritis (RA) will inform how best to manage patients with both periodontitis and RA. This review seeks to provide an update on interventional and mechanistic investigations, including a brief summary of European Research programs investigating the link between periodontitis and RA. Recent

Nucleotide sequence of the leukotoxin gene from Actinobacillus actinomycetemcomitans: homology to the alpha-hemolysin/leukotoxin gene family [PDF]
Infection and Immunity, 1990 The leukotoxin produced by Actinobacillus actinomycetemcomitans has been implicated in the etiology of localized juvenile periodontitis. To initiate a genetic analysis into the role of this protein in disease, we have cloned its gene, lktA. We now present the complete nucleotide sequence of the lktA gene from A. actinomycetemcomitans.

Pathogens, 2020 Aggregatibacter actinomycetemcomitans is a periodontal pathogen colonizing the oral cavity in many individuals of the human population. It is equipped with several potent virulence factors that can cause cell death and induce or evade the host ...
