Core Tip

Core tip: New antiviral strategies have been developed, including the interferon/ribavirin-free therapy, to control hepatitis viruses replication. Although, IFN-free regimens have generated excitement among scientists, for the reason that they are better tolerated, they are not still able to completely eradicate the viruses. Here we underline the circadian relationship between host cell and hosted hepatitis viruses, that has to be taken into account in order to optimize the timing of therapeutic regimens, not only to minimize the pharmacological agents’ toxicity but also to improve the efficacy of treatment modalities through optimized timing of therapeutic regimens, targeting in a better way virus replication.
