Cellular Lysis

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 infection in vitro induces cell death of sheep choroid plexus cells (SCPC) by a mechanism that can be associated with apoptotic cell death. Here, the relative implication of several caspases during acute infection with MVV is investigated by employing diverse in vitro and in situ strategies. It was demonstrated using specific pairs of caspase substrates and inhibitors that, during in vitro infection of SCPC by MVV, the two major pathways of caspase activation (i.e. intrinsic and extrinsic pathways) were stimulated: significant caspase-9 and -8 activities, as well as caspase-3 activity, were detected. To study the role of caspases during MVV infection in vitro, specific, cell-permeable, caspase inhibitors were used. First, these results showed that both z-DEVD-FMK (a potent inhibitor of caspase-3-like activities) and z-VAD-FMK (a broad spectrum caspase inhibitor) inhibit caspase-9, -8 and -3 activities. Second, both irreversible caspase inhibitors, z-DEVD-FMK and z-VAD-FMK, delayed MVV-induced cellular lysis as well as virus growth. Third, during SCPC in vitro infection by MVV, cells were positively stained with FITC-VAD-FMK, a probe that specifically stains cells containing active caspases. In conclusion, these data suggest that MVV infection in vitro induces SCPC cell death by a mechanism that is strongly dependent on active caspases.

Unfrozen and frozen/thawed cells of Listeria monocytogenes strains Scott A, V7, and California were treated with lipase and/or lysozyme. Cells of strain Scott A were more susceptible to the lytic action of lysozyme than were cells of strains V7 and California. Treatment of unfrozen cells with lipase before exposure to lysozyme enhanced cellular lysis. This also was true for cells held frozen for up to 6 weeks before they were thawed and treated with enzymes. Some variation existed among strains of L. monocytogenes in their susceptibility to effects of lysozyme. Frozen storage of cells of all three strains increased their susceptibility to lysis by lipase, and this was related inversely with the percentage of cells that survived freezing and frozen storage. Transmission electron microscopy showed some enzyme-treated cells formed protoplasts.
