Abstract:
:Hand, foot and mouth disease is mainly caused by enterovirus A71 (EV-A71) and coxsackievirus A16 (CV-A16), but EV-A71 is also associated with severe neurological complications. Host factors may contribute to the different clinical outcomes of EV-A71 and CV-A16 infections. A neurovirulent EV-A71 strain (EV-A71/UH1) from a fatal case, a non-neurovirulent EV-A71 strain (EV-A71/Sha66) and a CV-A16 strain (CV-A16/22159) from cases of uncomplicated HFMD were used. Replication of the viruses in SK-N-MC (neuronal) and HT-29 (intestinal) cell lines correlated with the severity of clinical disease associated with each virus. EV-A71/UH1 showed the greatest replication in neuronal cells. In HT-29 cells, both EV-A71 strains replicated well, but CV-A16/22159 showed no effective replication. The proteomes of mock and infected SK-N-MC and HT-29 cell lines were compared by 2D-SDS-PAGE. The differentially expressed proteins were identified by MALDI-TOF/TOF analysis. There were 46 and 44 differentially expressed proteins identified from SK-N-MC and HT-29 cells, respectively, categorized under apoptosis, stress, cytoskeletal, energy metabolism proteins and others. Western blot validation showed that EV-A71/UH1 and CV-A16 also differentially induced proteins involved in viral RNA translation and host cell stress responses in neuronal and intestinal cell lines.
