Favipiravir inhibits in vitro Usutu virus replication and delays disease progression in an infection model in miceby Guerrero et al.
This study shows that treatment of mice with favipiravir (150 mg/kg/dose, BID, oral gavage) significantly reduced viral load in blood and tissues and significantly delayed virus-induced disease. The USUV mouse model is amenable for assessing the potential in vivo efficacy of (novel) USUV/flavivirus inhibitors.
Research Models and Tools for the Identification of Antivirals and Therapeutics against Zika Virus Infectionby Alves et al.
This review focuses on the recent advances regarding research models, as well as available experimental tools that can be used for the identification and characterization of potential antiviral targets and therapeutic intervention strategies.
This study provides key insights into how ZIKV may persist in semen and alter semen parameters, as well as a valuable tool for testing antiviral agents.
Replication of the Zika virus in different iPSC-derived neuronal cells and implications to assess efficacy of antiviralsby Lanko et al.
This study demonstrates for the first time that motor neurons support ZIKV replication and these cells are as a consequence of ZIKV replication destroyed by the virus, and that human iPSC derived neuronal cells offer a physiologically relevant system to assess the potential antiviral effect of small molecule inhibitors of viral replication that are being developed to clear ZIKV infections in the nervous system.
