Virus-immune cytotoxic T cells can inhibit effectively growth of vaccinia virus in acutely infected target cells in vitro by destroying infected target cells before infectious virus progeny is assembled. Together with the fact that virus-specific T cells are demonstrable after 3 days, very early during infection, and with strong circumstantial evidence from adoptive transfer models in vivo, these data suggest that in some virus infections T cells may in fact act cytolytically in vivo to prevent virus growth and spread and be an important early antiviral effector mechanism.
病毒免疫细胞毒性T细胞可通过在传染性病毒子代组装之前破坏被感染的靶细胞,在体外有效抑制痘苗病毒在急性感染靶细胞中的生长。鉴于病毒特异性T细胞在感染后3天即感染早期就可被检测到,以及体内过继转移模型提供的有力间接证据,这些数据表明,在某些病毒感染中,T细胞实际上可能在体内发挥溶细胞作用,以阻止病毒生长和传播,并且是一种重要的早期抗病毒效应机制。
