Activation of Bacteroides fragilis toxin by a novel bacterial protease contributes to anaerobic sepsis

Nature Network Boston, 2016
Bacteroides fragilis is the leading cause of anaerobic bacteremia and sepsis. Enterotoxigenic strains that produce B. fragilis toxin (BFT, fragilysin) contribute to colitis and intestinal malignancy, yet are also isolated in bloodstream infection.

Improvement of the Anticancer Efficacy of PD‐1/PD‐L1 Blockade: Advances in Molecular Mechanisms and Therapeutic Strategies

MedComm, Volume 6, Issue 8, August 2025.
Mechanisms of alleviating resistance to PD‐1/PD‐L1 blockade by IFN‐α and IFN‐β. In these mechanisms, the “yin‐yang balance” is disrupted, thus preventing T cells from attacking cancer cells. Restoring this balance may improve the efficacy of anti‐PD‐1/PD‐L1 therapy and reinvigorate T cells and other immune cells to target and destroy cancer cells ...

Gut microbiome compositional and functional features associate with Alzheimer's disease pathology

Alzheimer's &Dementia, Volume 21, Issue 7, July 2025.
Abstract BACKGROUND The gut microbiome is a potentially modifiable risk factor for Alzheimer's disease (AD); however, understanding of its composition and function regarding AD pathology is limited. METHODS Shallow‐shotgun metagenomics was used to analyze the fecal microbiome of participants in the Wisconsin Microbiome in Alzheimer's Risk Study ...

Influence of Citrobacter freundii on NINJ2 Expression and Oxaliplatin Resistance in Colorectal Cancer

Cancer Medicine, Volume 14, Issue 13, July 2025.
Oxaliplatin resistance was found to be induced in colon cancer cells by bacterial filtrates from Citrobacter freundii. This resistance was associated with downregulation of the NINJ2 gene, which was found to suppress apoptosis and reactive oxygen species.

Cancer stem cells: Bridging microenvironmental interactions and clinical therapy

Clinical and Translational Medicine, Volume 15, Issue 7, July 2025.
Cancer stem cells (CSCs) drive tumor progression through their dynamic self‐renewal capacity, epigenetic plasticity, and drug resistance. These cells interact bi‐directionally with the tumor ecosystem to promote immunosuppressive reprogramming and metastatic spread.
