The sRNA vvrr1 Modulates the VarS/VarA‐Csr System via LeuO to Regulate Biofilm Formation and Virulence in Vibrio alginolyticus

Animal Research and One Health, EarlyView.
vvrr1, a small RNA, post‐transcriptionally represses the transcriptional regulator LeuO, which directly inhibits the VarS/VarA two‐component system. This triggers a Csr cascade that relieves LuxO repression, ultimately modulating exopolysaccharide production to control biofilm formation and virulence in Vibrio alginolyticus.

Elimination of Fusobacterium nucleatum With Biomimetic Nanoparticles to Reverse Tumor Immunosuppression and Enhance Colorectal Cancer Therapy

Exploration, EarlyView.
Tumor‐related pathogenic bacteria can affect the treatment efficiency of tumors. Therefore, we have designed a nanoparticle that can accurately target tumor cells and related pathogenic bacteria, reverse the immunosuppressive effect of pathogenic bacteria on tumors, and synergistically enhance tumor treatment efficiency through sonodynamic therapy ...
