We also previously showed that TCR1045-T cells infiltrate ID8VEGF tumors, but that antitumor activity is limited by low persistence.10 To evaluate if TCR1045/Fas-4-1BBtm T cells persist better in mouse ovarian tumors than control TCR1045 cells, T cells were transferred into ID8VEGF tumor-bearing mice, following an established protocol.10 Briefly, 5×106 ID8VEGF cells were injected intraperitoneally (i.p.)into 8 week-old female C57Bl/6 mice. This evidence concerns the gene FAS and neoplasm.
