摘要
采用Whiteside方法从19例RCC中成功地分离到17例TIL,经19天培养,TIL数量平均达1.04×10^(11)个细胞。杀伤自体肿瘤活性为57.87±5.88%,对Raji细胞的杀伤活性为37.39±10.88%,两组间比较差异有非常显著性(P<0.01)。明显高于外周血淋巴细胞(PBL)的杀伤肿瘤活性(22.39±8.84%)。TIL中CD_3和CD8细胞分别为69.93±6.80%及40.21±6.80%,均明显高于PBL中的CD3和CD_8细胞(P<0.01)。TIL对K562细胞的杀伤活性为26.89±12.79%,提示活化的TIL有显著的杀伤肿瘤活性,且对自体肿瘤细胞的杀伤活性更为显著,其杀伤活性主要由T淋巴细胞介导。
Tumor infiltrating lymphoctytes(TIL)suspensions were successfully isolated with the Whiteside method from 19 renal cell carcinoma(RCC).After cultured for an average of 19 days(13 ̄28 days),the mean TIL recovery was 1.04 ×10 ̄(11) pertumor.The cytotoxic activity of TII against autologous tumor cells was signifi cantly higher than that against Raji cells(P< 0.01).The latter was however significantly higher than that of peripheral blood lymphocytes(PBL)(P< 0.01). Phenotype studies showed that the mean percentage of CD_3 cells was 69. 93 % and CD8 cells 40.21% both of which were significantly higher than those in PBL(P<0.01). The results denoted that activated TIL has relatively specific antitumor activity against autologous RCC,mediated mainly by T lymphocytes, and the antitumor activity is stronger than that of PBL.
