Figure 5. Antigen-specific CD8+ T cells increase in the lungs and spleens following influenza infection.
Mice were infected with PR8 and Aichi Influenza viruses or mock PBS infected on day 0 and day 35, respectively. Six days after the second infection spleens and lungs were harvested and analyzed by Flow Cytometry for the presence of T cells staining with the Dimer-X reagent (as described in Methods and Materials). Data are representative of two experimental repeats of least n=3 animals per group and are expressed as means ± SEM.
