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(More)
We have determined the structure of a human rhinovirus (HRV)-Fab complex by using cryoelectron microscopy and image reconstruction techniques. This is the first view of an intact human virus complexed with a monoclonal Fab (Fab17-IA) for which both atomic structures are known. The surface area on HRV type 14 (HRV14) in contact with Fab17-IA was(More)
Rhinovirus (RV) infections can alter lower airway physiology and inflammation, yet the characteristics of RV replication in lower airway cells are incompletely understood. An RV serotype 16 (RV16)-specific monoclonal antibody was identified. Immunohistochemistry and an infectious center assay were used to quantitate the infectivity of RV16 in primary(More)
The structures of three different human rhinovirus 14 (HRV14)-Fab complexes have been explored with X-ray crystallography and cryoelectron microscopy procedures. All three antibodies bind to the NIm-IA site of HRV14, which is the beta-B-beta-C loop of the viral capsid protein VP1. Two antibodies, Fab17-IA (Fab17) and Fab12-IA (Fab12), bind bivalently to the(More)
Respiratory viruses, including rhinoviruses, infect respiratory epithelium and induce a variety of cytokines and chemokines that can initiate an inflammatory response. Cytokines, such as interferon (IFN)-␥ and tumor necrosis factor (TNF)-␣ , could enhance epithelial cell activation by inducing virus receptors. To test this hypothesis, effects of IFN-␥ or(More)
Antibodies represent a major component of the mammalian immunological defense against picornavirus infection. The work reviewed here examines structural details of antibody-mediated neutralization of human rhinovirus 14 (HRV14) using a combination of crystallography, molecular biology and electron microscopy. The atomic structures of the Fab fragment from a(More)
