The CD3+CD4-CD8- T cell ratio in Balb/cJ mice was raised significantly since 24 h post MHV-3 infection and reach the peak until day 3. The CD3+CD4+CD8- and CD3+CD4-CD8+ T cell ratios degraded accordingly.

• Balb/cJ小鼠于感染后24h外周血、脾脏以及肝脏T淋巴细胞中DNT细胞比率明显升高直至小鼠3d后全部死亡,CD3+CD4+CD8-和CD3+CD4-CD8+T淋巴细胞比率相应下降;
