From: Anti-West Nile virus activity of in vitro expanded human primary natural killer cells
Anti-IFN-γ antibody neutralized NK cell supernatant inhibition of WNV replication in Vero cells. NK culture supernatants with and without antibodies to IFNs were added to WNV-infected or control Vero cultures 2 hours post infection. Supernatants from testing and control Vero cell cultures were collected 10 days post WNV infection, and WNV RNA was extracted with Qiagen viral extraction kit and then analyzed with TaqMan RT-PCR. The NK cell culture supernatant was from D2NK cells.
