以前,干扰素作用的抑制剂已经从促分裂原刺激的小鼠脾细胞中分离出来。这种抑制剂与IFN-γ分子相关,可能代表一种改变的IFN-γ分子,其不再能诱导有效的抗病毒状态。本报告进一步研究了这种抑制剂的生物学特性。抑制剂活性与干扰素试验中使用的病毒无关。还发现抑制剂活性具有种属特异性。小鼠抑制剂不抑制人IFN-γ或人IFN-β的抗病毒活性。然而,抑制剂的产生并不限于小鼠系统。抑制剂也存在于人IFN-γ制剂中。该抑制剂似乎不直接与IFN-γ竞争特异性细胞表面受体,因为抑制剂活性与干扰素浓度无关。抑制剂的存在允许一种独特的,尽管降低水平的抗病毒保护发展。增加干扰素浓度并不能增加抑制剂允许的抗病毒保护水平。这种干扰素作用的抑制剂可能代表了一种天然机制,由此IFN-γ诱导的作用在体内受到调节。
Previously an inhibitor of interferon action had been isolated from mitogen stimulated mouse spleen cells. This inhibitor was associated with the IFN-γ molecule and might possibly represent an altered IFN-γ molecule which can no longer induce an effective antiviral state. This report further investigates the biological properties of this inhibitor. Inhibitor activity is independent of the virus used in the interferon assay. Inhibitor activity has also been found to be species specific. Mouse inhibitor does not inhibit the antiviral activity of either human IFN-γ or human IFN-β. However, inhibitor production is not limited to the mouse system. Inhibitor is also present in preparations of human IFN-γ. The inhibitor does not appear to directly compete with IFN-γ for a specific cell surface receptor since inhibitor activity is independent of interferon concentration. The presence of inhibitor allows a unique, albeit reduced level of antiviral protection to develop. Increasing concentrations of interferon do not increase the level of antiviral protection allowed by the inhibitor. This inhibitor of interferon action may represent a natural mechanism whereby IFN-γ-induced effects are regulated in vivo.
