Three-dimensional structure of poliovirus receptor bound to poliovirus.
Poliovirus initiates infection by binding to its cellular receptor (Pvr). We have studied this interaction by using cryoelectron microscopy to determine the structure, at 21-A resolution, of poliovirus complexed with a soluble form of its receptor (sPvr). This density map aided construction of a homology-based model of sPvr and, in conjunction with the known crystal structure of the virus, allo...
متن کاملBlockade of the poliovirus-induced cytopathic effect in neural cells by monoclonal antibody against poliovirus or the human poliovirus receptor.
The poliovirus (PV)-induced cytopathic effect (CPE) was blocked in neural cells but not in HeLa cells by the addition of monoclonal antibody (MAb) against PV or the human PV receptor (CD155) 2 h postinfection (hpi). Since each MAb has the ability to block viral infection, no CPE in PV-infected neural cells appeared to result from the blockade of multiple rounds of viral replication. Pulse-label...
متن کاملInteraction of poliovirus with its receptor affords a high level of infectivity to the virion in poliovirus infections mediated by the Fc receptor.
Poliovirus infects susceptible cells through the poliovirus receptor (PVR), which functions to bind virus and to change its conformation. These two activities are thought to be necessary for efficient poliovirus infection. How binding and conformation conversion activities contribute to the establishment of poliovirus infection was investigated. Mouse L cells expressing mouse high-affinity Fcga...
متن کاملTransgenic mice carrying the human poliovirus receptor: new animal models for study of poliovirus neurovirulence.
Recombinant viruses between the virulent Mahoney and attenuated Sabin 1 strains of poliovirus type 1 were subjected to neurovirulence tests using a transgenic (Tg) mouse line, ICR-PVRTg1, that carried the human poliovirus receptor gene. The Tg mice were inoculated intracerebrally with these recombinant viruses and observed for clinical signs, histopathological lesions, and viral antigens as par...
