Differential expression of NeurimmiRs in human microglial cells after JEV infection. CHME3 cells were mock-infected or infected with JEV. Total RNA was isolated from cells at different time points. (A) Relative abundance of six NeurimmiRs obtained from human miRNA microarray was shown as log2 fold-change. (B) Levels of miR-155 and miR-146a were determined by qPCR and plotted as relative to that seen in the mock-infected cells. Data were normalized against U6 snRNA. h, hours; JEV, Japanese encephalitis virus; pi, post-infection. *, P <0.05; **, P <0.005.
