Extracellular Vesicles of Streptococcus anginosus Mediate Gastritis via Epithelial Barrier Disruption and Macrophage‐driven Inflammation

open access: yesAdvanced Science, Volume 13, Issue 19, 2 April 2026.
Streptococcus anginosus extracellular vesicles (SA‐EVs) accumulate in gastric tissue, disrupt epithelial tight junctions, and induce gastritis characterized by neutrophil infiltration and elevated cytokines (TNF‐α, IL‐6, IL‐17A). Proteomics identifies TMPC and FBP62 as key SA‐EVs virulence factors; their genetic deletion attenuates inflammation ...
