To clarify the role of electrostatic interactions in the binding of Sindbis virus (SNV) to cell membrane receptors, we investigated the effect of different polyions on the initial steps of infection of Vero cells by the virus. Several polyanions (mucin, heparin, polygalacturonic acid) and polycations (polylysine, protamine, polybrene) were able to reduce(More)
The role of electrostatic interactions in the attachment and fusion at acidic pH of Sindbis virus (SNV) with goose erythrocytes was studied, investigating the effect of several anionic and cationic polyelectrolytes on SNV hemagglutination and hemolysis. In order to establish the target of active drugs, the compounds were incubated either with the virus(More)
