Amodiaquine Enhances Anti‐Melanoma Efficacy of Attenuated Salmonella via Targeting Glutathione Reductase in Neutrophils

open access: yesAdvanced Science, Volume 13, Issue 17, 23 March 2026.
This study shows that Salmonella VNP20009 recruits pro‐tumor neutrophils that reduce its anticancer efficacy. Combining VNP with amodiaquine selectively eliminates these neutrophils by targeting glutathione reductase. A GR‐shRNA‐loaded VNP strain was further developed, demonstrating an innovative strategy integrating drug repurposing with synthetic ...
