Exosomes from TMEV-infected microglia activate bystander astrocytes. Exosomes were isolated from uninfected (naïve) microglia or TMEV-infected microglia and placed on naive astrocytes for 24 h. Astrocytes were lysed, RNA isolated, converted to cDNA, and analyzed by real time PCR for expression of TMEV (A), IFNα (B), IFNβ (C), IL-6 (D), IL-12 (E), TNFα (F), and CCL2 (G). Significant difference was determined by the one way ANOVA and Bonferroni’s multiple comparison test (*p < 0.001) based on unstimulated microglia. These are representative graphs from one experiment of four independent repeated experiments.
