Synergistic Promotion of Triple‐Negative Breast Cancer Tumorigenesis and Metastasis by Oral Polystyrene Nanoplastics Exposure via Alloprevotella‐Derived Glutamate and Platelet Activation

Advanced Science, Volume 12, Issue 46, December 11, 2025.
Polystyrene nanoplastics (PS‐NPs) administered via oral exposure accelerate triple‐negative breast cancer (TNBC) progression by synergistically modulating gut microbiota‐derived glutamate production and platelet activation. This study uncovers a pivotal crosstalk between microbial metabolites and platelet‐tumor interactions, offering mechanistic ...

Differential response of the cynomolgus macaque gut microbiota to Shigella infection. [PDF]

PLoS ONE, 2013
Little is known about the role of gut microbiota in response to live oral vaccines against enteric pathogens. We examined the effect of immunization with an oral live-attenuated Shigella dysenteriae 1 vaccine and challenge with wild-type S. dysenteriae 1

Comparative Analysis of Fecal Microbiota in Healthy Controls and Pancreatic Cancer Patients: A Focus on Tumor Localization Differences in Pancreatic Head and Body–Tail

Cancer Medicine, Volume 14, Issue 24, December 2025.
ABSTRACT Background Pancreatic cancer (PC) remains one of the most lethal malignancies worldwide, characterized by late‐stage diagnosis and a poor prognosis. This study explores the clinical, biochemical, and gut microbiota differences between PC patients and healthy controls (CTRL), as well as between subgroups of PC patients with pancreatic head ...

MALDI-TOF MS Using a Custom-Made Database, Biomarker Assignment, or Mathematical Classifiers Does Not Differentiate Shigella spp. and Escherichia coli

Microorganisms, 2022
Shigella spp. and E. coli are closely related and cannot be distinguished using matrix-assisted laser desorption-ionization time-of-flight mass spectrometry (MALDI-TOF MS) with commercially available databases.

PGLYRP4 Enhances Shigella flexneri Virulence by Promoting virF Transcription via the CpxA/R Two‐Component System

MicrobiologyOpen, Volume 14, Issue 6, December 2025.
Shigella can use the host's innate immune system to optimize the expression of its virulence factors. The PGLYRP4 protein, a member of the host's innate immune system, increases VirF expression in Shigella by stimulating the CpxA/R TCS, thereby enhancing the expression of the virulence system.

The labile antigens of Shigella dysenteriae Shiga [PDF]

Journal of Hygiene, 1948
Our data suggest that there are four different thermolabile antigens in S. dysenteriae (Shiga) appearing in different combinations in the five variants described. These antigens are:1. The agglutination-inhibiting factor ‘I’, found in variants 1 and 3, which is a typical surface antigen.2.
