IL37 and Familial prostate cancer: When these PC3-PSMA + prostate cancer cells were used for long-term co-culture experiments with different engineered CAR T cells, the duo-CAR T cells co-expressing the IL-23mAb and PSMA-mAb in T2A expression system had a significant higher population than the rest three different CAR T cells in co-culturing experiments at day 28, 35 and 42 (Fig. 1E), indicating the secretion of IL23 by PC3 (PSMA+) cells stimulate the growth or proliferation of IL23mAb-T2A-PSMA-CAR T cells.
