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

The role of type 1 and curli fimbriae of Shiga toxin-producing Escherichia coli in adherence to abiotic surfaces

, 2002
Biofilm formation on abiotic surfaces may provide a source of microbial contamination and may also enhance microbial environmental survival. The role of fimbrial expression by Shiga toxin-producing Escherichia coli (STEC) in biofilm formation is poorly ...

Subversion of a family of antimicrobial proteins by Salmonella enterica

Frontiers in Cellular and Infection Microbiology
Salmonella enterica is a food-borne pathogen able to cause a wide spectrum of diseases ranging from mild gastroenteritis to systemic infections. During almost all stages of the infection process Salmonella is likely to be exposed to a wide variety of ...

Oophorectomy‐Corrected Ovarian Cancer Incidence, Survival, and Mortality by Subtype, Race, Ethnicity

Cancer Medicine, Volume 15, Issue 6, June 2026.
When combining ovarian, fallopian tube, and peritoneal sites, the decrease in ovarian cancer incidence is slower compared to ovarian cancer alone, suggesting reclassification of ovarian cancers as fallopian tube cancers. ABSTRACT Background Most ovarian cancers are detected at advanced stages, with poor outcomes.

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,

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

Binding characteristics ofEscherichia colitype 1 fimbriae in the human kidney [PDF]

FEMS Microbiology Letters, 1987
Binding of the Escherichia coli type 1 fimbriae to frozen sections of human kidney was examined by indirect immunofluorescence. The purified fimbriae bound specifically to the luminal and cytoplasmic aspects of proximal tubules and to the connective tissue layer of veins and arteries. Distal tubules, collecting ducts, glomeruli and vascular endothelium

Regulation of type 1 fimbriae synthesis and biofilm formation by the transcriptional regulator LrhA of Escherichia coli

, 2005
Type 1 fimbriae of Escherichia coli facilitate attachment to the host mucosa and promote biofilm formation on abiotic surfaces. The transcriptional regulator LrhA, which is known as a repressor of flagellar, motility and chennotaxis genes, regulates ...
