Bacterial Outer Membrane Vesicles in Potentiating Cancer Vaccines: Progress and Prospects
Advanced Science, EarlyView.Bacterial outer membrane vesicles (OMVs) have emerged as versatile platforms for cancer vaccine development owing to their intrinsic immunostimulatory properties and high engineering flexibility. This review summarizes OMV biology, immune mechanisms, and engineering strategies that enhance vaccine efficacy, discusses key translational challenges, and ...

Neisseria gonorrhoeae Porin Modulates Phagosome Maturation [PDF]
Journal of Biological Chemistry, 1998 The porin (PorB) of Neisseria gonorrhoeae has been implicated in the pathogenesis of this species. Porin is believed to translocate from the bacterial outer membrane into target cell membranes affecting various cell functions. Here we investigated the effect of porin on phagosome maturation.

Advanced Science, EarlyView.Urinary Fusobacterium nucleatum–derived outer membrane vesicles are shown to promote bladder cancer lymphatic metastasis. The vesicle protein FomA activates TLR2/NF‐κB signaling in tumor cells, induces IL‐6 secretion, and drives M2b macrophage polarization and VEGF‐C–dependent lymphangiogenesis, revealing a microbiota‐driven mechanism linking tumor ...

Borrelia burgdorferi tolerates alteration to P66 porin function in a murine infectivity model
Frontiers in Cellular and Infection MicrobiologyBorrelia burgdorferi exists in a complex enzootic life cycle requiring differential gene regulation. P66, a porin and adhesin, is upregulated and essential during mammalian infection, but is not produced or required within the tick vector.

Rhenium Complexes as Antimicrobial Agents
Helvetica Chimica Acta, EarlyView.Rhenium complexes are stepping into the fight against superbugs. Our new review explores how these metallic complexes could inspire the next generation of antimicrobial therapies. ABSTRACT The escalating crisis of antimicrobial resistance (AMR) necessitates the exploration of unconventional therapeutic scaffolds.

The Emerging Role of Microbial Extracellular Vesicles in Neuroinflammation and Neurodegeneration
Medicine Bulletin, EarlyView.ABSTRACT Neurodegenerative and neuropsychiatric disorders are increasingly viewed as systemic conditions shaped by interactions among peripheral immunity, microbiota, and the central nervous system. However, the mechanisms linking microbial activity to neuroinflammation and neurodegeneration remain poorly defined.

Microbiology and Immunology, EarlyView.ABSTRACT The emergence of bacteria with both antimicrobial resistance and high virulence has become a global health concern, underscoring the urgent need to elucidate the molecular basis underlying these traits. Here, we employed the silkworm (Bombyx mori) infection model, which is suitable for high‐throughput screening, together with an Escherichia ...
