Although, the majority of mice transplanted with both control and DUSP6-T cells developed progressive weight loss and died of GVHD (Supplementary Fig. 30a, b), the untransduced (ΔNGFR−) donor T-cell population predominated over DUSP6-overexpressing T cells at the time of death (Fig. 7j). This evidence concerns the gene DUSP6 and graft versus host disease.
