Proteome alterations in human host cells infected with coxsackievirus B3

Coxsackievirus B3 (CVB3) is a common factor in human myocarditis. The interplay between host factors and virus components is crucial for the fate of the infected cells. Despite that, host protein responses, which characterize CVB3-induced diseases, have not yet been determined in detail. To investigate the nature of modified protein patterns in infected human cells compared with uninfected cells, two-dimensional gel electrophoresis in combination with matrix-assisted laser desorption/ionization-mass spectrometry were used. The regulated proteins, e.g. nucleophosmin (nucleolar protein B23), lamin, the RNA-binding protein UNR and the p38 mitogen-activated protein kinase, were sorted according to their functional groups and interpreted in the context of the myocarditis process.
