Figure Lengend Snippet: CBNK-EVs rapidly impair ZIKV infectivity and protect host cells. (a) Multiplex immunohistochemical analysis of ZIKV infection in neural progenitor cells. Co-staining for Nestin (neural progenitor cells, green) and ZIKV E protein (red) was performed, and double-positive cells were quantified across six random fields, mean ± SD, ∗P < 0.05. Scale bar, 20 μm. (b) KEGG pathway enrichment bubble plot from RNA-seq of HTR-8/Svneo cells treated with CBNK-EVs (3 × 10 11 particles/mL, 10 μl) and ZIKV (MOI = 1) for 1 h. (c) GSEA analysis of transcriptomic data from HTR-8/Svneo cells. (d) Western blot analysis of ZIKV E and ZIKV NS5 protein levels after co-incubation of ZIKV particles with CBNK-EVs for the indicated time periods (0–30 min) prior to infection. (e) The abundance of NK cell-associated proteins in CBNK-EVs. ∗P < 0.05 (one-way ANOVA).
