| Abstract: | The pathogenesis of infection of mice by the mammalian reoviruses involves several discrete steps. Each of the three viral outer capsid proteins has a highly distinct and specialized role: one protein (sigma 1) binds to cell surface receptors; a second protein (mu 1C) determines the capacity for viral growth at mucosal surfaces; and the third protein (sigma 3) is responsible for inhibiting cell macromolecular synthesis. A detailed picture of the molecular basis of reovirus virulence and attention is now emerging. |
