We report the first atomic resolution structure of an animal virus, human rhinovirus 14. It is strikingly similar to known icosahedral plant RNA viruses. Four neutralizing immunogenic regions have been identified. These, and corresponding antigenic sequences of polio and foot-and-mouth disease viruses, reside on external protrusions. A large cleft on each icosahedral face is probably the host cell receptor binding site. 相似文献

Summary In the brain wall of different vertebrate species, ependymal cells of different type occur. These cells possess protuberances which protrude into the ventricle.Although cytologically these structures are all variations of one theme, they must at present be interpreted in different ways as regards function.Probably these cell types form a complex system for the regulation of the cerebrospinal fluid. It remains possible that one or more of these cell types act as light receptors. 相似文献
