Inflammatory and Immunological Basis of Periodontal Diseases
Journal of Periodontal Research, EarlyView.The periodontal lesion emerges as an evolving immunological battlefield, where host–microbiome interactions, dysregulated immune responses, fragile resolution mechanisms, and inflammophilic dysbiosis converge to shift the balance from homeostasis to unrestrained tissue destruction.

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 ...

Maturation of fimbria precursor protein by exogenous gingipains inPorphyromonas gingivalisgingipain-null mutant [PDF]
FEMS Microbiology Letters, 2007 Porphyromonas gingivalis expresses several virulence factors such as fimbriae and proteases, termed gingipains, which are enzymes that process precursor fimbriae proteins. Thus, gingipain-null mutants lack mature fimbriae. Membrane vesicle-depleted supernatants (VDS) containing soluble gingipains were prepared as an exogenous gingipain fraction ...

Curli of Uropathogenic Escherichia coli Enhance Urinary Tract Colonization as a Fitness Factor
Frontiers in Microbiology, 2019 Curli, a type of fimbriae widely distributed in uropathogenic Escherichia coli (UPEC), are involved in adhesion to human bladder cell surfaces and biofilm development. The role of UPEC curli was evaluated in a murine model of urinary tract infection. The

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).

Characterization of Porphyromonas gingivalis Mfa1 fimbriae.
, 2017 Porphyromonas gingivalis, an obligate anaerobic bacterium associated with chronic periodontitis, utilizes various virulence factors to achieve pathogenicity, one of which is the Mfa1 fimbriae.

Permissive linker insertion sites in the outer membrane protein of 987P fimbriae of Escherichia coli
Journal of Bacteriology, 1994 The FasD protein is essential for the biogenesis of 987P fimbriae of Escherichia coli. In this study, subcellular fractionation was used to demonstrate that FasD is an outer membrane protein. In addition, the accessibility of FasD to proteases established the presence of surface-exposed FasD domains on both sides of the outer membrane.

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

Role of Mfa5 in Expression of Mfa1 Fimbriae in Porphyromonas gingivalis
, 2016 Fimbriae are protein-based filamentous appendages that protrude from the bacterial cell surface and facilitate host adhesion. Two types of fimbriae, FimA and Mfa1, of the periodontal pathogen Porphyromonas gingivalis are responsible for adherence to ...
