ABSTRACT:
A norovirus-permissive cell culture infected with a norovirus, and methods of culturing a norovirus, are disclosed. Norovirus-permissive cells include dendritic cell-lineage cells, and macrophage-lineage cells, such as dendritic cells, and macrophages having a deficiency in a cellular anti-viral pathway such as a STAT-1-dependent pathway, an interferon receptor-dependent pathway, or a PKR-dependent pathway. Also disclosed are methods of screening anti-viral compounds against norovirus-permissive cells infected with norovirus, and norovirus adapted to grow in fibroblasts as well as macrophages that are not deficient in a cellular anti-viral pathway. Methods of making a norovirus vaccine are also disclosed.
