Aedes albopictus (mosquito) cells persistently infected with Sindbis virus for a period of 6 months release into the medium a low-molecular-weight material capable of specifically reducing the yields of Sindbis virus during the "acute phase" of infection in mosquito cells. The antiviral activity was produced in detectable levels at 3 days after infection, and its concentration in the extracellular medium increased thereafter. The antiviral activity was inactivated by treatment with the enzyme protease K and heat. It was not activated by treatment with antibody prepared against extracts of Sindbis virus-infected BHK-21 cells. The antiviral activity differs from interferon produced by vertebrate cells in that it is virus specific as well as cell specific.
白纹伊蚊(蚊子)细胞被辛德毕斯病毒持续感染6个月后,会向培养基中释放一种低分子量物质,该物质能够在蚊子细胞感染的“急性期”特异性降低辛德毕斯病毒的产量。抗病毒活性在感染后3天达到可检测水平,此后其在细胞外培养基中的浓度增加。该抗病毒活性经蛋白酶K处理和加热后失活。用针对辛德毕斯病毒感染的BHK - 21细胞提取物制备的抗体处理不能激活它。这种抗病毒活性与脊椎动物细胞产生的干扰素不同,因为它具有病毒特异性和细胞特异性。
