Porphyromonas gingivalis outer membrane vesicles exacerbate retinal microvascular endothelial cell dysfunction in diabetic retinopathy

Frontiers in Microbiology, 2023
Diabetic retinopathy (DR) is one of the leading causes of blindness. Periodontitis is one of the highest oral incidences and has been closely related to various systemic conditions through Porphyromonas gingivalis (P. gingivalis). P.

DRD2 Deficiency Underlies Pituitary Adenoma Dependent on Escherichia coli Translocation from the Gut

Advanced Science, EarlyView.
Dopamine receptor D2 (DRD2) deficiency disrupts epithelial barrier integrity in both the gut and pituitary gland, facilitating translocation of gut‐derived Escherichia coli into pituitary tissue. Intratumoral E. coli are phagocytosed by microglia, triggering GSDMD‐dependent pyroptosis and HMGB1 release, which subsequently activates MAPK signaling to ...

Porphyromonas gingivalis outer membrane vesicles augments proliferation and metastasis of oral squamous cell carcinoma cells

BMC Oral Health
Background Porphyromonas gingivalis (P. gingivalis) is closely related to Oral squamous cell carcinoma (OSCC), and P. gingivalis outer membrane vesicles (OMVs) is the main pathogenic factor, which is associated with periodontitis, atherosclerosis and ...

Gut Microbiota‐Non‐Coding RNA Axis in Immune Modulation and Disease: From Mechanisms to Clinical Translation

Advanced Science, EarlyView.
ABSTRACT Immune homeostasis is indispensable for preserving organismal integrity, orchestrated through complex molecular networks encompassing immune cell dynamics, microbial cues, and epigenetic regulation. Among these, the gut microbiota‐non‐coding RNA (ncRNA) axis has recently garnered substantial attention as a multifaceted modulator of host ...

P. GINGIVALIS–LPS-INDUCED NLRP3 INFLAMMASOME ACTIVATION DRIVES AD PATHOLOGIES [PDF]

Innov Aging, 2023
Abstract Alzheimer’s disease (AD) is the leading cause of dementia among older adults. AD is characterized by amyloid-β deposition, abnormal hyperphosphorylation of tau leading to the formation of neurofibrillary tangles, and neuroinflammation. Porphyromonas gingivalis, the keystone-pathogen of periodontitis, is being increasingly linked

Tobacco Upregulates P. gingivalis Fimbrial Proteins Which Induce TLR2 Hyposensitivity

PLoS ONE, 2010
Tobacco smokers are more susceptible to periodontitis than non-smokers but exhibit reduced signs of clinical inflammation. The underlying mechanisms are unknown. We have previously shown that cigarette smoke extract (CSE) represents an environmental stress to which P. gingivalis adapts by altering the expression of several virulence factors - including

Cascade Therapy of Periodontitis via Sequential Release of Ribosome‐Targeting Antimicrobial Peptide and Irisin From a Multifunctional MOF‐Based System

Advanced Science, EarlyView.
This study presents a novel strategy for periodontitis treatment by co‐delivering a membrane‐ and ribosome‐targeting antimicrobial peptide GF and Irisin through a pH‐responsive metal‐organic framework. The system enables sequential release, providing rapid antibacterial action, anti‐inflammatory and antioxidative effects, as well as promoting bone ...

Nucleoside‐Based Hydrogel Platform Synergizes with Photothermal Effects for Enhanced Biofilm Eradication Against Periodontitis

Advanced Science, EarlyView.
A synergistic antibiofilm hydrogel platform (ZBAg@FNP) is developed by encapsulating an organic small‐molecule photothermal agent (FNP) within a silver ion‐mediated supramolecular hydrogel (ZBAg), enabling photothermal disruption of biofilm integrity and controlled Ag⁺ ion release upon irradiation.

Immunization withPorphyromonas gingivalisCapsular Polysaccharide PreventsP. gingivalis-Elicited Oral Bone Loss in a Murine Model [PDF]

Infection and Immunity, 2003
ABSTRACTThe capsular polysaccharide (CPS) of the periodontal pathogenPorphyromonas gingivalisis an important virulence factor for this organism. We purifiedP. gingivalisCPS, immunized mice with this antigen, and assessed the vaccine potential ofP. gingivalisCPS by using the murine oral challenge model. Animals immunized withP.
