NK cells and supernatants inhibited WNV replication in Vero cells. NK cells or culture supernatants were added to WNV-infected or control Vero cultures 2 hours post infection. Supernatants from testing and control Vero cell cultures were collected on day 10 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.
