In present study, we deeply investigated the expression patterns of IFITM1 and IFITM1-mediated antiviral response induced by H9N2 virus infection and inactivated viral particle inoculation in HUVECs. Epithelial cells that are considered target cells of the influenza virus were selected as a reference control. The results indicated that the cellular interaction between intracellular molecules and viral particles might be involved in the induction of IFITM1 expression in HUVECs. To determine the antiviral activity of IFITM1 protein induced by H9N2 virus infection, HUVECs or BEAS-2Bs were infected with H9N2 virus at MOI of 5 and incubated for 1 h, then cells were transfected with IFITM1 specific siRNA or control siRNA for 36 h. ./cache/cord-339744-xrit0w5i.txt ./txt/cord-339744-xrit0w5i.txt
