TGFβ/BMP immune signaling affects abundance and function of C. elegans gut commensals. [PDF]

, 2019
The gut microbiota contributes to host health and fitness, and imbalances in its composition are associated with pathology. However, what shapes microbiota composition is not clear, in particular the role of genetic factors.

A Bifunctional T3SS‐Effector Simultaneously Cleaves Host MAP Kinase and Inhibits PPM1A Phosphatase

Advanced Science, EarlyView.
Pathogenic bacteria exploit the metalloprotease effector NleD to subvert host defenses. Structural, biochemical, and infection analyses reveal a bifunctional mechanism by which NleD binds and inhibits the host phosphatase PPM1A while preserving its proteolytic activity against MAPKs.

Self-reinoculation with fecal flora changes microbiota density and composition leading to an altered bile-acid profile in the mouse small intestine [PDF]

, 2019
Background: The upper gastrointestinal tract plays a prominent role in human physiology as the primary site for enzymatic digestion and nutrient absorption, immune sampling, and drug uptake.

Extracellular Vesicles of Streptococcus anginosus Mediate Gastritis via Epithelial Barrier Disruption and Macrophage‐driven Inflammation

Advanced Science, EarlyView.
Streptococcus anginosus extracellular vesicles (SA‐EVs) accumulate in gastric tissue, disrupt epithelial tight junctions, and induce gastritis characterized by neutrophil infiltration and elevated cytokines (TNF‐α, IL‐6, IL‐17A). Proteomics identifies TMPC and FBP62 as key SA‐EVs virulence factors; their genetic deletion attenuates inflammation ...

The Research Progress on Intestinal Stem Cells and Its Relationship with Intestinal Microbiota

Frontiers in Immunology, 2017
The intestine is home to trillions of microorganisms, and the vast diversity within this gut microbiota exists in a balanced state to protect the intestinal mucosal barrier.

MGM as a Large‐Scale Pretrained Foundation Model for Microbiome Analyses in Diverse Contexts

Advanced Science, EarlyView.
We present the Microbial General Model (MGM), a transformer‐based foundation model pretrained on over 260,000 microbiome samples. MGM learns contextualized microbial representations via self‐supervised language modeling, enabling robust transfer learning, cross‐regional generalization, keystone taxa discovery, and prompt‐guided generation of realistic,

MicroRNA‐microbiota interactions: Emerging strategies for modulating intestinal homeostasis and enhancing host health

iMetaOmics
Long‐term artificial selection and environmental shifts have driven adaptive changes in both the host genome and the intestinal microbiota. The complex symbiotic relationship between these two has become essential for maintaining intestinal homeostasis ...

Para-cresol production by Clostridium difficile affects microbial diversity and membrane integrity of Gram-negative bacteria [PDF]

, 2018
Clostridium difficile is a Gram-positive spore-forming anaerobe and a major cause of antibiotic-associated diarrhoea. Disruption of the commensal microbiota, such as through treatment with broad-spectrum antibiotics, is a critical precursor for ...

Intestinal Microbiota in Colorectal Cancer Surgery

Cancers, 2020
The intestinal microbiota consists of numerous microbial species that collectively interact with the host, playing a crucial role in health and disease. Colorectal cancer is well-known to be related to dysbiotic alterations in intestinal microbiota. It is evident that the microbiota is significantly affected by colorectal surgery in combination with ...
