In vitro (FLC-Vt) or in vivo (FLC-V) passaged Friend erythroleukaemia cells of DBA/2 origin were tested for susceptibility to natural resistance (NR) in vivo or to NK cell activity in vitro. Scarcely oncogenic FLC-Vt cells were highly susceptible to in vivo NR (measured as rapid organ clearance or growth inhibition in lethally irradiated mice) or to in vitro NK attack. Conversely, highly oncogenic FLC-V cells were weakly susceptible to NR and to NK as well. These data seem to point out that natural immunity, which is up-regulated by endogenous or exogenous interferons, can play a significant role in surveillance against mouse leukaemic cells of retrovirus origin.
对源自DBA/2的经体外传代(FLC-Vt)或体内传代(FLC-V)的弗氏红白血病细胞进行了体内对天然抵抗力(NR)或体外对NK细胞活性的敏感性测试。几乎无致癌性的FLC-Vt细胞对体内NR(以在致死剂量照射小鼠中的快速器官清除或生长抑制来衡量)或体外NK攻击高度敏感。相反,高致癌性的FLC-V细胞对NR和NK也均不敏感。这些数据似乎表明,由内源性或外源性干扰素上调的天然免疫在监测逆转录病毒起源的小鼠白血病细胞方面可发挥重要作用。
