Similarly, when compared to mean velocities of CD8+ T cells in the livers of Pyuis4(−) sporozoite immunized mice (9.18±0.94 μm/min), the mean velocities of splenic CD8+ T cells adoptively transferred into PyXNL-GFP infected mice were significantly lower when adoptive transfer was done at 18 h (1.45±0.57 μm/min) and 42 h (1.51±0.14 μm/min) post infection (Fig.6A). This evidence concerns the gene CD8A and infection.
