Abstract:
Objective:To select an appropriate dosage of IL-2 for tumor infiltrating lymphocyte(TIL).Methods:Isolated by the attachment method we established,TIL was cultivated in self-supernatant of malignant pleura,with three different concentrations of IL-2,such as 6000u per ml,6000u per ml for the first administration followed by 1000u per ml,or 1000u per ml.The expansion,killing activity and phenotype changes of TIL cultured in different cultures were assessed.Results:As cultured in self-supernatant of malignant pleura fluid,the concentrations of IL-2,such as 6000u per ml or 6000u per ml for the first administration followed by 1000u per ml seemed benefit for TIL proliferation.Conclusion:6000u per ml of IL-2 for the first administration was very important.It could help TIL to activate and proliferate early.The study described here offers the possibility for TIL cultured in vitro self-supernatant of malignant pleura fluid in vitro for a short time,and then reinfuse to thorax for further expanding and controlling the malignant pleura effusion in the presence of IL-2,and thereby minimizing the risks of contamination.
