未观察到肿瘤坏死因子对HL60或U937细胞有抗病毒作用。然而,它确实显著增强了干扰素-γ介导的U937细胞的抗病毒活性。干扰素-γ使U937细胞的(2‘-5’)寡聚(A)合成酶活性增加(2.5倍),但与肿瘤坏死因子-α+干扰素-γ联合作用不能显著提高该酶活性(20-40倍)。这一增加与U937细胞中(‘2-5’)寡聚(A)合成酶mRNA水平的极大增加有关。在HL60细胞中没有观察到这样的影响。此外,结合研究和交联分析表明,干扰素-γ调节U937细胞中的肿瘤坏死因子-α受体而不改变其性质,但在HL60细胞中不这样做。
TNF was not observed to have an antiviral effect on either HL60 or U937 cells. However, it did significantly enhance interferon (IFN)‐γ‐mediated antiviral activity in U937 cells. Treatment of U937 cells with IFN‐γ enhanced (2′–5′) oligo (A) synthetase activity (2.5‐fold) but treatment with TNF did not Combined treatment with TNF‐α + IFN‐γ increased this activity dramatically (20–40‐fold). This increase correlated with the very large increase in the (‘2–5’) oligo (A) synthetase mRNA level in U937 cells. No such effects were observed in HL60 cells. Furthermore, binding studies and cross‐linking analysis showed that IFN‐γ modulated TNF‐α receptors in U937 cells without altering their properties, but did not do so in HL60 cells.
