Abstract:
:Cultured post-fused human skeletal muscle monolayers exposed to WSN influenza A virus were analyzed by scanning and transmission electron microscopy. At 12-14h post-inoculation (p.i.), affected mononuclear cells retracted from the cell surface, but remained anchored to the substrate by taut filar processes. Retraction was accompanied by shortening of microvilli, appearance of hemispherical cytoplasmic protrusions and corrugation of the surface proper. These changes were more pronounced at 24 and 48h p.i. The rounded, moribund mononuclear cells eventually detached from the substratum. Surface alterations were accompanied by the intracellular appearance of electron-dense nuclear inclusions (often associated with the nucleolus) and paracrystalline ribosomestudded cytoplasmic bodies, which increased in size and number with time. In myotubes, distinct surface alterations appeared later (24h p.i.). Early myotube retraction was accompanied by accentuation of the longitudinally oriented surface pleats and appearance of "blebs" followed by cell-rounding. At 48-72 h, many myotubes detached from the substratum. The surfaces of those still adhering appeared corrugated. Intranuclear and cytoplasmic inclusions accumulated, and budding virions, often filamentous, could be demonstrated at the plasmalemma of mononuclear cells and myotubes. Late (end-stage) cytopathic effects included clumping of chromatin, breakdown of the nuclear envelope, disappearance of cortical and endoplasmic cytofilaments, mitochondrial swelling, and vesiculation of surface membranes. The lesions leading to cell injury and cell death appeared to be due to massive accumulation of virus-induced products that altered cellular metabolism, with physical and functional abnormalities of surface membranes.
