Porphyromonas gingivalis Induces Apoptosis and Autophagy via ER Stress in Human Umbilical Vein Endothelial Cells

Mediators of Inflammation, 2018
It has been reported that periodontitis is associated with an increased risk of atherosclerosis. Accumulating evidence suggests that endothelial dysfunction is an early marker for atherosclerosis.

Porphyromonas gingivalis lipopolysaccharide alters atherosclerotic-related gene expression in oxidized low-density-lipoprotein-induced macrophages and foam cells [PDF]

, 2011
The molecular mechanism between atherosclerosis formation and periodontal pathogens is not clear although positive correlation between periodontal infections and cardiovascular diseases has been reported.

P. gingivalis accelerates gingival epithelial cell progression through the cell cycle [PDF]

Microbes and Infection, 2008
P. gingivalis, an opportunistic pathogen in periodontal disease, can reside within the epithelial cells that line the gingival crevice. A proteomic analysis revealed that infection of gingival epithelial cells with P. gingivalis induces broadly based changes in the level and phosphorylation status of proteins that exert multi-level control on the ...

CRP Deficiency Rescues Periodontitis‐Induced Hippocampal Neurogenesis Impairment by Suppressing OPC‐Derived BMP4 Signaling in Rats

Advanced Science, EarlyView.
Chronic periodontitis elevates circulating CRP, which enters the hippocampus to upregulate BMP4 in oligodendrocyte precursor cells (OPCs), thereby impairing neurogenesis and inducing anxiety/depression‐like behaviors in rats. Counteracting this pathway, CRP deficiency helps confer functional resilience to OPCs.

Porphyromonas Gingivalis Survives In BMECs By Kgp Inhibiting Lysosomal Acidification

International Dental Journal
Aim or purpose: This study aimed to investigate Porphyromonas gingivalis (P. gingivalis) persistence in human brain microvascular endothelial cells (BMECs), its impact on cellular lysosomal acidification and regulatory mechanisms, given that brain ...

Study on porphyromonas gingivalis- and porphyromonas endodontalis- mediated signaling pathway [PDF]

, 2019
It is known that anaerobic microbes like Porphyromonas gingivalis (P. gingivalis) are involved in the progression and initiation of multiple forms of periodontal disease such as chronic periodontitis.

Anthelmintic tolerance in free-living and facultative parasitic isolates of Halicephalobus (Panagrolaimidae) [PDF]

, 2012
Studies on anthelmintic resistance in equine parasites do not include facultative parasites. Halicephalobus gingivalis is a free-living bacteriovorous nematode and a known facultative parasite of horses with a strong indication of some form of tolerance ...

Multi‐Enzyme Mimetic Molybdenum Nitride Nanozymes Reshape Subgingival Microenvironment for Synergistic Periodontitis Therapy via ROS Regulation and Microbiome Remodeling

Advanced Science, EarlyView.
ABSTRACT Periodontitis, a chronic inflammatory disease initiated and sustained by plaque microorganisms and host immune response, remains an intractable oral disease and a leading cause of tooth loss worldwide. Traditional mechanical debridement and adjunctive antibiotic or antiseptic therapy often shows limited efficacy due to the complex anatomical ...

Macrophage Extracellular Traps in Immunity and Cancer

Advanced Science, EarlyView.
As a macrophage‐mediated innate defense mechanism, the dysregulated release of METs drives chronic inflammation and influences tumor progression. Furthermore, METs exhibit a functional duality within the tumor microenvironment, capable of both promoting and suppressing tumor development.

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 ...
