The survival curve analysis showed that around 90% of control mice (mice having only VECadCreERT2 or COUP-TF2flox/flox mice lacking CreERT2) were able to survive indefinitely (up to 25 days after infection), while ablation of COUP-TF2 (COUP-TF2EC−/−) significantly reduced the survival to less than 50% (Fig. 3E). Here, NR2F2 is linked to infection.
