Induction of Alpha/Beta Interferon by Myxoma Virus Is Selectively Abrogated When Primary Mouse Embryo Fibroblasts Become Immortalized
Keyword(s):
ABSTRACT Mouse embryo fibroblasts (MEFs) are a widely used cell culture system in life sciences, including virology. Here, we show that although primary MEFs are nonpermissive to myxoma virus replication, the corresponding immortalized MEFs support a highly productive myxoma virus infection. We further demonstrate that this permissive phenotype for myxoma virus in immortalized MEFs is due to the immortalization-associated selective block to the cellular alpha/beta interferon induction machinery involved in responding to myxoma virus challenge. Thus, our report presents a clear example, illustrating that a drastic phenotypic alteration can occur with respect to virus infection between primary cells and their immortalized counterparts.
