Choroid plexus remodeling linked to impaired CSF‐mediated clearance and Alzheimer's disease progression

Alzheimer's &Dementia, Volume 22, Issue 6, June 2026.
Abstract INTRODUCTION Impaired cerebrospinal fluid (CSF) ‐mediated clearance has been implicated in Alzheimer's disease (AD), but how choroid plexus (ChP) remodeling relates to these processes in vivo remains incompletely understood. METHODS In a large ADNI cohort, we integrated structural magnetic resonance imaging (MRI), amyloid/tau positron emission

Aggregatibacter Actinomycetemcomitans – A Tooth Killer? [PDF]

Journal of Clinical and Diagnostic Research, 2014
Strong evidence is available on Aggregatibacter actinomycetemcomitans (A.a) on its role as the causative agent of localised juvenile periodontitis (LJP), a disease characterised by rapid destruction of the tooth-supporting tissues.

The Silent Link: Exploring the Impact of Periodontal Diseases on Head and Neck Carcinogenesis

Clinical and Experimental Dental Research, Volume 12, Issue 3, June 2026.
ABSTRACT Objectives Oral dysbiosis can accelerate the progression of head and neck squamous cell carcinoma (HNSCC) by fostering a pro‐inflammatory, immunosuppressive, and metabolically altered environment. This narrative review examines the relationships between periodontitis‐associated bacteria and HNSCC, focusing on their impact on oncogenic pathways,

Structural and adhesive properties of the long polar fimbriae protein LpfD from adherent-invasiveEscherichia coli [PDF]

Acta Crystallographica Section D Biological Crystallography, 2015
Crohn's disease (CD) is an inflammatory bowel disease characterized by an exaggerated immune response to commensal microbiota in the intestines of patients. Metagenomic studies have identified specific bacterial species and strains with increased prevalence in CD patients, amongst which is the adherent-invasiveEscherichia coli(AIEC) strain LF82.

H-NS is the major repressor of Salmonella Typhimurium Pef fimbriae expression

, 2019
Fimbriae play an important role in adhesion and are therefore essential for the interaction of bacteria with the environments they encounter. Most of them are expressed in vivo but not in vitro, thus making difficult the full characterization of these ...

Effective assembly of fimbriae in Escherichia coli depends on the translocation assembly module nanomachine [PDF]

, 2016
Outer membrane proteins are essential for Gram-negative bacteria to rapidly adapt to changes in their environment. Intricate remodelling of the outer membrane proteome is critical for bacterial pathogens to survive environmental changes, such as entry ...

RNAs Associated With Bacterial Outer Membrane Vesicles: Structural Insights Into Surface Composition

Journal of Extracellular Vesicles, Volume 15, Issue 6, June 2026.
This work uncovers a new layer of bacterial communication. We show that RNAs, aided by the Hfq RNA‐chaperone, are not only packed inside Gram negative Outer Membrane Vesicles (OMVs) but can also be embedded in their membranes. This suggests that bacteria may use surface‐exposed RNAs to directly interact with host cells. Overall, our results broaden the

Dancing to Another Tune—Adhesive Moonlighting Proteins in Bacteria

Biology, 2014
Biological moonlighting refers to proteins which express more than one function. Moonlighting proteins occur in pathogenic and commensal as well as in Gram-positive and Gram-negative bacteria.
