Leucocytes from normal individuals and from patients with acute myeloid leukaemia (AML) in remission receiving active immunotherapy with allogeneic AML blasts (AML-I) were cultured for 6 days with AML-I blasts, Burkitt's lymphoma cells (BL) or lymphoblastoid cells (LCL). The leucocytes were then tested for cell-mediated cytotoxicity (CMC) against 51Cr-labelled AML-I, BL or LCL target cells. There was no substantial difference in the CMC of leucocytes from patients and normals cultured without stimulation, and tested against AML-I, BL or LCL targets. Patient's leucocytes stimulated in vitro with AML-I had a greater frequency of positive CMC responses against AML-I, BL and LCL than normal individuals. The results suggest that co-cultivation of leucocytes with AML-I blasts reactivates memory cytotoxic leucocytes in AML patients receiving immunotherapy and that this test may be useful in measuring the effectiveness of immunotherapy.
将来自正常个体以及处于缓解期且接受同种异体急性髓细胞白血病母细胞主动免疫治疗(AML-I)的急性髓细胞白血病(AML)患者的白细胞,与AML-I母细胞、伯基特淋巴瘤细胞(BL)或淋巴母细胞样细胞(LCL)共同培养6天。然后检测这些白细胞对51Cr标记的AML-I、BL或LCL靶细胞的细胞介导细胞毒性(CMC)。在未受刺激情况下培养并针对AML-I、BL或LCL靶细胞进行检测时,患者和正常人白细胞的CMC没有实质性差异。体外经AML-I刺激的患者白细胞对AML-I、BL和LCL的阳性CMC反应频率高于正常个体。结果表明,白细胞与AML-I母细胞共培养可使接受免疫治疗的AML患者体内的记忆性细胞毒性白细胞重新激活,并且该检测可能有助于评估免疫治疗的效果。
