摘要

Viruses and their hosts have co-evolved for million years.In order to successfully replicate their genome,viruses need to usurp the biosynthetic machinery of the host cell.Depending on the complexity and the nature of the genome,replication might involve or not a relatively large subset of viral products,in addition to a number of host cell factors,and take place in several subcellular compartments,including the nucleus,the cytoplasm,as well as virus-induced,rearranged membranes.Therefore viruses need to ensure the correct subcellular localization of their effectors and to be capable of disguising from the cellular defensive mechanisms.In addition,viruses are capable of exploiting host cell activities,by modulating their post-translational modification apparatus,resulting in profound modifications in the function of cellular and viral products.Not surprisingly infection of host cells by these parasites can lead to alterations of cellular differentiation and growing properties,with important pathogenic consequences.In the present hot topic highlight entitled“Reprogramming the host:modification of cell functions upon viral infection”,a number of leading virologists and cell biologist thoroughly describe recent advances in our understanding of how viruses modulate cellular functions to achieve successful replication and propagation at the expenses of human cells.
