The number of splenic virus specific CD8+ T cells and CD4+ T cells is lower in JNK1−/− mice than in either JNK2−/− or JNK+/+ mice during the acute response but not during the secondary response. JNK1−/−, JNK2−/−, and JNK+/+ mice were injected intraperitoneally with LCMV ARM 2 × 105 PFU. Spleens were harvested at day 7, 8, 14, or 60 postinfection or 4 d after a challenge with Cl-13 (106 PFU intravenously) in memory animals. Spleen cells were stimulated for 5 h in vitro with virus specific peptides GP aa 33–41 or NP aa 396–404, then stained for CD8 and intracellular IFN-γ. The number of virus specific T cells was calculated from the number of total spleen cells obtained per animal. Data represent average values obtained from three animals per group and are representative of two independent experiments. *P < 0.05, #P = 0.057 compared with JNK+/+.
