The activity of the antiviral protein induced by various ratios of poly rI.rC and diethylaminoethyl (DEAE)-dextran was studied. It was found that, when large doses of poly rI.rC were used, very little viral interference was observed. This effect was initially attributed to the cells being refractory for production of antiviral protein. Subsequent experiments offered alternative explanations suggesting that, at any given dosage of poly rI.rC, an excess of DEAE-dextran is necessary for the production of viral interference. It is suggested that DEAE-dextran acts by exposing a cell receptor site for poly rI.rC.
聚胞苷酸(poly rI.rC)和二乙氨基乙基(DEAE)-葡聚糖诱导的抗病毒蛋白的活性。结果发现,当使用大剂量的poly rI.rC时,观察到的病毒干扰很少。这种效应最初被归因于细胞对抗病毒蛋白的产生具有抗性。随后的实验提供了其他解释,表明在任何给定剂量的poly rI.rC下,产生病毒干扰都需要过量的DEAE-葡聚糖。有人提出,DEAE-葡聚糖通过暴露细胞上的poly rI.rC受体位点来发挥作用。
