Theiler's murine encephalitis virus (TMEV) infection in mice is an established model of CNS demyelinating diseases. The aim of the study was to determine the chronological pattern of lesion development in this model of monophasic fulminant demyelinating disease. We followed six highly susceptible interferon-gamma receptor knockout mice with serial in vivo(More)
Brain MRI in multiple sclerosis (MS) frequently shows areas of hypointensity in the white matter on T1 weighted sequences ("T1 black holes"). These areas are thought to be consistent with irreversible axonal loss. In this study T1 black holes were characterized in Theiler's Murine Encephalitis Virus infection, an established model of demyelinating diseases(More)
The human monoclonal antibody rHIgM22 enhances remyelination following spinal cord demyelination in a virus-induced murine model of multiple sclerosis. Using three-dimensional T2-weighted in vivo spinal cord magnetic resonance imaging (MRI), we have therefore assessed the extent of spinal cord demyelination, before and after 5 weeks of treatment with(More)
We compared CNS disease following intracerebral injection of SJL mice with Daniel's (DA) and BeAn 8386 (BeAn) strains of Theiler's murine encephalomyelitis virus (TMEV). In tissue culture, DA was more virulent then BeAn. There was a higher incidence of demyelination in the spinal cords of SJL/J mice infected with DA as compared to BeAn. However, the extent(More)
Differentiating between injurious and reparative factors facilitates appropriate therapeutic intervention. We evaluated the role of tumor necrosis factor alpha (TNFalpha) in parenchymal brain pathology resolution following virus-induced encephalitis from a picornavirus, Theiler's murine encephalomyelitis virus (TMEV). We infected the following animals with(More)
