The Keystone‐Pathogen Hypothesis Updated: The Role of Porphyromonas gingivalis in Periodontitis

Journal of Periodontal Research, EarlyView.
Porphyromonas gingivalis orchestrates a coordinated manipulation of immune and inflammatory responses in periodontal tissues which leads to the generation of a dysbiotic, subgingival biofilm community, and progression of periodontitis. The type 9 secretion system, lipid A modification, and the formation of outer membrane vesicles are important ...

Uropathogenic Escherichia coli P and Type 1 fimbriae act in synergy in a living host to facilitate renal colonization leading to nephron obstruction. [PDF]

PLoS Pathogens, 2011
The progression of a natural bacterial infection is a dynamic process influenced by the physiological characteristics of the target organ. Recent developments in live animal imaging allow for the study of the dynamic microbe-host interplay in real-time ...

Nanoparticles in Periodontology and Implant Dentistry: From Mechanisms to Clinical Applications

Journal of Periodontal Research, EarlyView.
Nanotechnology holds significant promise in improving dental care, yet there is a need for more reliable clinical studies to validate its effectiveness and safety. ABSTRACT Recent advances in nanotechnology are reshaping the landscape of periodontology and implant dentistry, particularly through the application of nanoparticles (NPs).

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

Phenotypic Expression of Type 1 Klebsiella pneumoniae Fimbriae in Escherichia coli HB101

مجلة مركز بحوث التقنيات الاحيائية, 2011
Four selected isolates of K. pneumoniae subsp. pneumoniae were tested for adhesion and the results revealed that isolates MK20, MK1, MK2, MK6 displayed adhesive capability with means (76.25 ± 6.0),(75.88 ± 5.13), (69.83 ± 8.43), (27.4±4.65) bacteria ...

The Oral‐Gut Axis: Bidirectional Interactions Between Microbiome and Diseases

Journal of Periodontal Research, EarlyView.
This study aims to summarize the mechanisms underlying ectopic colonization of the gut by oral pathobionts and the microbial and host factors that regulate this process. ABSTRACT Increased colonization of typically oral microorganisms is frequently observed in the gut mucosa or lumen of individuals with gastrointestinal disorders, including patients ...

Activation of the NLRP3 Inflammasome Pathway by Uropathogenic Escherichia coli Is Virulence Factor-Dependent and Influences Colonization of Bladder Epithelial Cells

Frontiers in Cellular and Infection Microbiology, 2018
The NLRP3 inflammasome and IL-1β release have recently been suggested to be important for the progression of urinary tract infection (UTI). However, much is still unknown regarding the interaction of UPEC and the NLRP3 inflammasome.

Osteoporosis and Periodontitis: Two‐Way Epidemiological and Mechanistic Evidence

Journal of Periodontal Research, EarlyView.
This review investigates the main mechanistic pathways connecting local periodontitis to systemic osteoporosis. Seven interconnected mechanisms are identified. ABSTRACT Osteoporosis and periodontitis are highly prevalent, chronic inflammatory diseases that constitute a major global health burden.

The export systems of type 1 and F1C fimbriae are interchangeable but work in parental pairs [PDF]

Journal of Bacteriology, 1995
Type 1 and F1C fimbriae are surface organelles of Escherichia coli which mediate receptor-specific binding to different host surfaces. Such fimbriae are found, among others, on strains associated with urinary tract infections. Biosynthesis of type 1 and F1C fimbrial organelles requires individual, specialized two-component assembly systems.

TMEM16A chloride channels in the female reproductive tract and their role in normal and dysfunctional pregnancy and labour

The Journal of Physiology, EarlyView.
Abstract figure legend TMEM16A plays a pivotal role in setting the duration of the action potential plateau in human uterine smooth muscle. An increase in TMEM16A expression in labour underpins a lengthening of the plateau and this provides time for the contraction to become larger and longer, important for timely successful labour.
