title: [Study of the antigenic structure of the E1 glycoprotein of the Venezuelan equine encephalomyelitis virus using monoclonal antibodies].
abstract: The collection of eight rat and mouse hybridomas secreting the high affinity monoclonal antibodies to glycoprotein E1 of the Venezuelan equine encephalomyelitis has been obtained. The antigenic structure of E1 protein has been studied with the use of these antibodies for the strains Trinidad, TC-83 and 230 of the virus. Antigenic map of glycoprotein E1 based on competition radioimmunoanalysis is proposed. Five sites are mapped including eight epitopes binding monoclonal antibodies. Antibodies to sites E1-1, E1-3 and E1-5 are crossreactive in interaction with the virus of Venezuelan equine encephalomyelitis, while antibodies to site E1-5 interact also with the virus of tick-borne encephalitis. Antibodies to site E1-1 possess the protective effect and lack the neutralizing effect in tissue cultures. Antibodies to all sites of E1 protein are devoid of ability to neutralize the Venezuelan equine encephalitis virus.
