Infection of BALB/c mouse cells with UV-irradiated herpes simplex virus (HSV) types 1 and 2 resulted in activation of a xenotropic type C virus detected by infectious center formation in permissive rat cells. The levels of type C virus activated by HSV were related to the UV dose and the multiplicity of infection used. The ability of HSV to activate type C virus was eliminated by heat-inactivation and by neutralization with specific antiserum against HSV, but was not affected by purification or treatment with DNase and RNase. Maximum levels of type C virus in the cells and medium were observed within 1 day after HSV infection, and the levels returned to control cell values within 3-4 days. The possible significance of these findings with respect to the putative oncogenic potential of HSV is discussed.
用紫外线照射的1型和2型单纯疱疹病毒(HSV)感染BALB/c小鼠细胞,导致一种嗜异性C型病毒被激活,该病毒可通过在允许性大鼠细胞中形成感染中心来检测。HSV激活的C型病毒水平与紫外线剂量和所用感染复数有关。HSV激活C型病毒的能力可通过热灭活和用抗HSV的特异性抗血清中和而消除,但不受纯化或用DNA酶和RNA酶处理的影响。在HSV感染后1天内观察到细胞和培养基中C型病毒的最高水平,并且在3-4天内这些水平恢复到对照细胞的值。讨论了这些发现关于HSV假定致癌潜力的可能意义。
