Administration of WT iTreg cells 2 days after low-dose C. albicans infection partly rescued the survival of Xiap−/− mice; 60% of infected Xiap−/− mice that received WT iTreg cells survived 40 days after infection, whereas all untreated Xiap−/− mice had died by 18 days post-infection (Fig. 6b). This evidence concerns the gene XIAP and infection.
