Figure 1. NK cells are required for the control of VV infection in vivo.

Figure 1

Female C57BL/6 mice were depleted of NK cells with anti-NK1.1 antibodies (25 µg) on days −3 and 0 (+anti-NK1.1) or left untreated (Control), followed by infection with VV on day 0. (A) 48 h after infection, splenocytes were assayed for NK lytic activity on YAC-1 cells for 4 hr at different effector∶target ratios. Naïve splenocytes (Naïve) were used for comparison. The percentage of specific lysis is shown. (B) The ovaries were assayed for viral load. Data represents viral titer ± SD as pfu per ovary.
