In this study we analysed the in vitro effect of recombinant interferon gamma on cytotoxic activities mediated by both lymphoid and polymorphonuclear cells from 16 patients with myelodysplastic syndromes. Our results indicate the inability of interferon to restore the defective natural killer activity, natural killer cells and lectin-induced cytotoxicity. On the contrary we detected a boosting effect on the depressed polymorphonuclear cell cytotoxic activities. In our view, the ability of interferon to potentiate polymorphonuclear cell lytic efficiency could support an alternative defensive pathway against either neoplastic or infectious agents.
在本研究中,我们分析了重组干扰素γ对16例骨髓增生异常综合征患者的淋巴细胞和多形核细胞介导的细胞毒性活性的体外作用。我们的结果表明,干扰素无法恢复缺陷的自然杀伤活性、自然杀伤细胞和凝集素诱导的细胞毒性。相反,我们检测到对降低的多形核细胞细胞毒性活性有增强作用。我们认为,干扰素增强多形核细胞裂解效率的能力可能支持针对肿瘤或感染因子的另一种防御途径。
