ABSTRACT
Objective To investigate the mechanisms of attachment of respiratory syncytial virus(RSV) to human airway epithelial cells.Methods Attachment of RSV to CFBE was quantitatively assessed by flow cytometry.Various polyclonal and monoclonal antibodies to RSV and heparin were pre-incubated with RSV.The blocking effects of these antibodies and heparin on attachment were evaluated.Results CFBE cells reduced capacity being bound by RSV.All the antibodies used were failed to block attachment of RSV on CFBE,whereas heparin blocked RSV attachment in a dose-response manner and the blokade by heparin was almost complete at the concentration of 0.4 mg/L.Conclusions Flow cytometry provides direct evaluation of attachment without growth of virus.Heparin-like molecules on cell surface of CFBE appears to be involved in attachment between RSV and human epithelial cells.
