Abstract

The present study examined the protective effect of IFN-alpha against mouse cytomegalovirus (MCMV) infection in embryo fibroblasts (MEF) of genetically resistant (C3H/HeJ) and susceptible (C57BL/6) mouse strains. At a M.O.I. of 1 IFN-alpha was protective in C3H/HeJ-MEF but not in C57BL/6-MEF. Dot-blot analysis during MCMV replication in C3H/HeJ-MEF showed that IFN-alpha pretreatment reduced the steady state level of immediate early and late mRNAs but partially reduced early gene expression.

干扰素对小鼠巨细胞病毒复制的影响。
本研究研究了ifn - α对小鼠巨细胞病毒(MCMV)感染的保护作用,这些小鼠的基因抗性(C3H/HeJ)和易感(C57BL/6)小鼠的胚胎成纤维细胞(MEF)。在mo.i为1时,ifn - α对C3H/HeJ-MEF有保护作用,而对C57BL/6-MEF无保护作用。MCMV在C3H/HeJ-MEF中复制期间的Dot-blot分析显示,ifn - α预处理降低了即时早期和晚期mrna的稳态水平,但部分降低了早期基因的表达。
