Abstract:Enterovirus 71 (EV71) is a major causative factor of hand, foot and mouth disease (HFMD). Currently, the mechanism of HFMD is not clearly understood, and neither vaccine nor antiviral therapy is available. As a capsid protein of EV71, VP1 plays an important role during the adsorption and penetration of EV71. The presence of the VP1-specific neutralizing epitopes makes it an important position in the EV71 vaccine research. This review article provides a summary of the structure, function and associated vaccine of EV71 VP1.
