人们认为病毒通过感染、复制和释放的迭代过程在易感细胞中传播,因此传播速率受到复制动力学的限制。在这里,我们证明痘苗病毒每 75 分钟就会在一个细胞中传播,比其复制周期允许的速度快四倍。为了解释这种现象,我们发现新感染的细胞表达两种表面蛋白,将细胞标记为感染的,并通过利用细胞机制,诱导重复感染的病毒体排斥未感染的细胞。从机制上讲,蛋白质 A33 和 A36 的早期表达对于病毒粒子的排斥和快速传播至关重要,表达这些蛋白质的细胞可以快速排斥外源病毒粒子。其他病毒可能存在额外的传播机制,其传播速度也比复制动力学预测的要快。
Viruses are thought to spread across susceptible cells through an iterative process of infection, replication, and release, so that the rate of spread is limited by replication kinetics. Here, we show that vaccinia virus spreads across one cell every 75 minutes, fourfold faster than its replication cycle would permit. To explain this phenomenon, we found that newly infected cells express two surface proteins that mark cells as infected and, via exploitation of cellular machinery, induce the repulsion of superinfecting virions away toward uninfected cells. Mechanistically, early expression of proteins A33 and A36 was critical for virion repulsion and rapid spread, and cells expressing these proteins repelled exogenous virions rapidly. Additional spreading mechanisms may exist for other viruses that also spread faster than predicted by replication kinetics.
