Native expression of GD2 on RB cells was demonstrated in human RB cell line - Y79RB….Y79RB-Wasabi cells co-cultured with 4SCAR-GD2 T cells demonstrated a significantly higher rate of tumor cell death...Close to 80% of tumor cells were killed by 24 h after co-culture...with the entire cell population had died by 3 days after co-culture...Thus, 4SCAR-GD2 T cells could effectively target and kill RB tumor cells with high specificity.
