No Dye Fits All: Illuminating the Challenges of Fluorescent Extracellular Vesicle Labeling

Journal of Extracellular Vesicles, Volume 15, Issue 5, May 2026.
ABSTRACT The widespread use of fluorescent dyes for extracellular vesicle (EV) labeling has substantially improved our ability to trace EVs in vitro, ex vivo, and in vivo. However, interpretability of these experiments remains limited by methodological challenges, including incomplete dye removal, dye‐associated artifacts, and intrinsic EV ...

Host Factor Induced Bacterial Extracellular Vesicles Promote Horizontal Gene Transfer in Vibrio cholerae

Journal of Extracellular Vesicles, Volume 15, Issue 5, May 2026.
Antimicrobial stressors, that is, bile or mitomycin C, induce enlarged, nucleic acid‐rich bacterial extracellular vesicles in Vibrio cholerae that facilitate horizontal gene transfer in vitro and during intestinal colonisation. The findings provide a detailed comparison of control versus stress‐induced vesicles, identify bile as a host factor shaping ...

Recent Advances in Nickel Catalysts for Sonogashira Coupling

ChemistryOpen, Volume 15, Issue 5, May 2026.
The Sonogashira coupling, catalyzed by transition metals, has become a valuable method for forming carbon‐carbon bonds. Nickel has gained considerable interest due to its lower cost and more environmentally friendly profile compared to palladium.
