From: Friend retrovirus infection induces the development of memory-like natural killer cells
Effect of transferred memory-like NK cells on viral loads. Mice were naïve or infected with FV for 28 days. Bone marrow, spleens and lymph nodes were removed and cells were pooled. NK cells were isolated from pooled bone marrow, spleens and lymph nodes (mixed NK cells) or from the livers. Isolated NK cells were transferred i. v. into naïve C57BL/6 mice. Recipient mice were infected with FV at the same day. At 3 dpi, mice were sacrificed and viral loads were determined by an IC assay in the spleen. Mean values are shown, with SEM indicated by error bars. At least seven animals from at least three independent experiments were used for the analysis. Statistically significant differences were analyzed by an unpaired t test and were indicated by *p < 0.05
