As one of the major causative agents of hand, foot and mouth disease (HFMD), enterovirus 71 (EV71) is a small, non-enveloped positive stranded RNA virus. Children suffering EV71 infection may cause severe symptoms including neurological complications, pulmonary edema and aseptic meningitis. EV71 is a neurotropic virus and it can cause the damage of nervous cells, cytokine storm and toxic substance. Identifying the factors that mediate viral binding or entry to host cells is important to uncover the mechanisms which viruses utilize to cause diseases in human body. Heat shock protein 70 (HSP70) is induced during virus infection and facilitates proper protein folding during viral propagation. The role that HSP70 plays during EV71 infection is still unclear. In this study, siRNA interference technique and transgenic technique were used to investigate the interaction between HSP70 and EV71 virus. The result demonstrated that the cell surface HSP70 is not essential for EV71 infection but helps the initial binding of virus to host cells and that multiple receptors are involved during EV71 infection. In addition, HSP70 was upregulated in human neuroblastoma cells (SK-N-SH) infected with EV71.
