Antibody-forming cell response to virus challenge in mice immunized with DNA encoding the influenza virus hemagglutinin.

abstract：:Ascoviruses (family Ascoviridae) are double-stranded DNA viruses with circular genomes that attack lepidopterans, where they produce large, enveloped virions, 150 by 400 nm, and cause a chronic, fatal disease with a cytopathology resembling that of apoptosis. After infection, host cell DNA is degraded, the nucleus fra...
