Polymorphisms in toll-like receptor (TLR) and β-defensin (DEFB) genes have been recognized as potential genetic factors that can influence susceptibility to and severity of periodontal diseases (PD). However, data regarding associations between these polymorphisms and PD are still scarce in North American populations, and are not available in HIV+ North American populations. In this exploratory...

enoxolone is a major component of a traditional plant called licorice. this substance has been found to contain some pharmaceutical properties including of both antiviral and antifungal activities. microbiological studies have identified more than seven periodontopathogens in the periodontal pockets, which less than 4 species were capnophile. the purpose of this study was to investigate the in ...

Three tetracyclines (tetracycline, doxycycline, and minocycline) were found to possess iron-chelating activity in a colorimetric siderophore assay. Determination of MICs indicated that the activity of doxycycline against the periodontopathogen Actinobacillus actinomycetemcomitans was only slightly influenced by the presence of an excess of iron that likely saturates the antibiotic. On the other...

To culture facultative and strict anaerobic bacteria is a well-established method for analyzing subgingival plaque samples. Micro-IDent and micro-IDent Plus (HAIN Lifescience GmbH, Nehren, Germany) tests are two commercially available rapid PCR-based methods for the identification and quantification of putative periodontopathogen bacteria. In this study, we compared these commercial PCR-based h...

The aim of this study was to determine the role of intracellular proteins in phagocytosis of opsonized Porphyromonas gingivalis by RAW264.7 cells, a murine macrophage-like cell line. This periodontopathogen was grown anaerobically and opsonized with an IgG2a murine monoclonal anti-P. gingivalis lipopolysaccharide antibody. RAW264.7 cells were preincubated with protein tyrosine kinase inhibitors...

BACKGROUND Evidence to date shows that mast cells play a critical role in immune defenses against infectious agents, but there have been no reports about involvement of these cells in eliminating periodontopathogens. In this study, the phagocytic ability of mast cells against Aggregatibacter actinomycetemcomitans compared with macrophages is evaluated. METHODS In vitro phagocytic assays were ...

Kartheyaene Jayaprakash (2016): Monocyte and Neutrophil Inflammatory Responses to the Periodontopathogen Porphyromonas gingivalis. Örebro studies in Medicine 138 Periodontitis is one of the most common adult infections. Duing bacteremia in healthy individuals or patients with chronic periodontitis, a number of oral bacteria such as Porphyromonas gingivalis encounter inflammatory cells in the bl...
