Abstract: Enterovirus 71 (EV71) causes Hand, foot and mouth disease (HFMD) and neither vaccine nor therapeutic treatment is currently available. In this study, antisera were raised in Balb/c mice against overlapping synthetic peptides spanning the VP1 capsid protein of EV71 strain 41. Two peptides, SP55 and SP70, elicited anti-EV71 neutralizing antibodies with SP70 eliciting a higher neutralizing antibody titer. Anti-SP70 antibodies were also able to confer good in vivo passive protection against homologous and heterologous EV71 strains in suckling Balb/c mice. This study also identified a major human IgG-specific immunodominant VP1 linear epitope by Pepscan analysis. To identify human CD4+ T-cell epitope, a virtual matrix-based prediction program (ProPred) was employed. Three predicted VP1 regions were tested in vitro for their abilities to induce CD4+ T-cell proliferation. Altogether, these can provide a better understanding in protective immunity and may help in the design of vaccines and diagnostic tools against EV71.
