To examine the requirement for autophagy in BMgraft Treg engraftment and GVHD control, we next utilized grafts comprised of BM from WT-FoxP3cre-YFP+ or Atg7fl/fl-FoxP3cre+-YFP+ donors supplemented with B6.FoxP3-RFP T cells (Figure 3C). This evidence concerns the gene FOXP3 and graft versus host disease.
