Cell surface vimentin serves as an attachment receptor for Enterovirus 71, and soluble vimentin or anti-vimentin antibodies can inhibit EV71 binding to host cells.
Does vimentin mediate the binding and infectivity of Enterovirus 71 in host cells?
Cell surface vimentin acts as an attachment receptor for Enterovirus 71, presenting a potential new target for treating EV71 infections.
UNLABELLED: Enterovirus 71 (EV71) is a highly transmissible pathogenic agent that causes severe central nervous system diseases in infected infants and young children. Here, we reported that EV71 VP1 protein could bind to vimentin intermediate filaments expressed on the host cell surface. Soluble vimentin or an antibody against vimentin could inhibit the binding of EV71 to host cells. Accompanied with the reduction of vimentin expression on the cell surface, the binding of EV71 to cells was remarkably decreased. Further evidence showed that the N terminus of vimentin is responsible for the interaction between EV71 and vimentin. These results indicated that vimentin on the host cell surface may serve as an attachment site that mediated the initial binding and subsequently increased the infectivity of EV71. IMPORTANCE: This study delivers important findings on the roles of vimentin filaments in relation to EV71 infection and provides information that not only improves our understanding of EV71 pathogenesis but also presents us with potentially new strategies for the treatment of diseases caused by EV71 infections.
