We injected tumor-bearing mice with a single infusion (i.p.)of TAG72-CAR T cells in combination with 10 mg/kg dex and huIL-7-secreting cells i.p. As in our ALL model, the combination of CAR+dex+IL-7 conferred significantly better tumor control than the CAR+IL-7 group (Figure 6G). Here, IL7 is linked to neoplasm.
