The discovery within the past decade that neural stem cells (NSCs) from the developing and adult mammalian brain can be propagated, cloned, and genetically manipulated ex vivo for ultimate transfer back into the CNS has opened the door to a novel…
The 4070A amphotropic murine leukemia virus (A-MuLV) has been variably reported to harbor neurovirulence determinants within its env gene. In this report we reexamined this issue by applying two approaches previously demonstrated to amplify murine…
The requirements for disease development in the mouse epidermal scarification-zosteriform model of HSV infection are likely to parallel those required for primary HSV disease of humans. HSV-1 strains, which are neuroinvasive in the mouse footpad…
The envelope protein (Env) from the CasBrE murine leukemia virus (MLV) can cause acute spongiform neurodegeneration analogous to that induced by prions. Upon central nervous system (CNS) infection, Env is expressed as multiple isoforms owing to…
Certain murine leukemia viruses (MLVs) can induce progressive noninflammatory spongiform neurodegeneration similar to that caused by prions. The primary MLV determinants responsible have been mapped to within the env gene; however, it has remained…
BACKGROUND: CasBrE is a neurovirulent murine leukemia virus (MLV) capable of inducing paralytic disease with associated spongiform neurodegeneration. The neurovirulence of this virus has been genetically mapped to the surface expressed subunit (SU)…
