Cytotoxic activity against maedi-visna virus-infected macrophages [PDF]

Journal of Virology, 1994
The cell type predominantly infected by maedi-visna virus (MVV) is the macrophage, and we have looked at the ability of MVV-infected macrophages to interact with cytotoxic T lymphocytes (CTL), important effector cells against virus infections. MVV-specific CTL precursors were detected, after in vitro culture with MVV antigen and recombinant human ...

Implication of caspases during maedi–visna virus-induced apoptosis

Journal of General Virology, 2002
Maedi–visna virus (MVV) causes encephalitis, pneumonia and arthritis in sheep.In vitro, MVV infection and replication lead to strong cytopathic effects characterized by syncytia formation and subsequent cellular lysis. It was demonstrated previously that MVV infectionin vitroinduces cell death of sheep choroid plexus cells (SCPC) by a mechanism that ...
