Abstract

Radiation leukemia virus, isolated from radiation-induced lymphomas in C57BL/Ka mice and propagated in that strain, is thymotropic and leukemogenic in vivo but replicates poorly, if at all, in mouse and mink fibroblast cultures in vitro. Comparative studies indicate that this naturally occurring virus is distinct from the previously recognized classes of endogenous murine ecotropic and xenotropic C-type viruses which are capable of replication on fibroblasts (fibrotropic) but are neither thymotropic nor leukemogenic. These studies also demonstrate that a differentiation-specific restriction system governing the replication of the murine ecotropic C-type viruses operates in addition to the previously defined Fv-1 and SRV gene restriction systems.

摘要

从C57BL/Ka小鼠辐射诱导的淋巴瘤中分离出来并在该品系中传代的辐射白血病病毒,在体内具有嗜胸腺性和致白血病性,但在体外小鼠和貂成纤维细胞培养物中复制能力很差,甚至根本不复制。比较研究表明,这种天然存在的病毒不同于先前公认的内源性鼠嗜亲性和异嗜性C型病毒类别,后者能够在成纤维细胞上复制(嗜纤维性),但既无嗜胸腺性也无致白血病性。这些研究还表明,除了先前定义的Fv-1和SRV基因限制系统外,还有一个控制鼠嗜亲性C型病毒复制的分化特异性限制系统在起作用。
