Transfer of serum from infected wild-type mice to Myd88 knockout mice rescues control of F-MLV.

<p>Myd88 knockout mice or heterozygous littermates were infected with F-MLV. At 7 dpi, infected mice were injected intraperitoneally with 0.5 ml serum from uninfected C57BL/6 mice or from C57BL/6 mice that had been infected with F-MLV for 14 days. At 14 dpi, the levels of viral focus-forming units in the spleens of infected mice were analyzed. Each bar represents the average of 4–7 mice from one of two independent experiments.
