摘要
目的:观察自体胸腔积液上清作为培养液对肿瘤浸润淋巴细胞(TIL)生长的影响.方法:恶性胸腔积液中的TIL经贴壁法分离后,分别采用含有细胞因子白细胞介素2(IL2)、CD3单克隆抗体(OKT3)及植物血球凝集素(PHA)的自体胸腔积液上清及含10%人AB型血清的RPMI1640进行培养,比较两种培养液对TIL的增殖速度、培养前后免疫表型变化和对自体肿瘤细胞的杀伤活性。结果:培养2周,经统计学比较发现,自体胸腔积液上清作为培养液对TIL的生长速度、免疫表型和对自体肿瘤细胞杀伤活性的影响与应用含10%人AB型血清的RPMI1640培养液培养无差异。结论:自体胸腔积液上清作为培养液培养TIL是可行的。为自体TIL疗法治疗恶性胸腔积液提供理论基础。
Objective:To study the effect of autologous supernatant of malignant pleura effusion and RPMI1640 with 10% AB+ serum on the culture of tumor infiltrating lymphocytes (TIL) in vitro. Methods:Isolated by the attachment method we established, TIL was cultured in either autologous supernatant of malignant pleura fluid or RPMI1640 with 10% AB+ serum, and various types of cytokines such as (IL-2,) PHA and antibody against CD3 (OKT3) were added into both cultures. The proliferation as well as the killing activity and the phenotype changes of TIL cultured in the two kinds of cultures were compared. Results:There was no difference in the proliferation or the killing activity in vitro as well as the phenotype changes of TIL between the two kinds of cultures. Conclusion: Autologous supernatant of malignant pleura fluid could be used as TIL culture medium. The method described here made it possible for TIL to be cultured in vitro for a short time, and then reinfused back to thorax for further expanding and controlling the malignant pleura effusion in the presence of IL-2, and it alsominimized the risks of contamination.
