Tsg101 is a component of the host cellular ESCRT machinery and is required for HIV-1 replication. Here, the authors show that disruption of ubiquitin binding of the Tsg101 UEV domain through commonly used drugs arrests virus assembly, which might facilitate the development of potent HIV inhibitors.
Influenza B virus causes substantial illness globally, particularly in children. Treatment options are limited, as the most widely used antiviral drug appears to be less effective than against influenza A. A new antibody targeting the influenza B neuraminidase shows promise in mice as a therapeutic option.
In a new report, adolescents with genotype 2 or 3 HCV infection who were given sofosbuvir and ribavirin showed a near 100% sustained virologic response. This study is the beginning of a new wave of treatments for paediatric HCV infection, forming part of a global strategy to eradicate viral hepatitis.
Unexpected data from new studies show that direct-acting antiviral agents might promote tumour occurrence in patients with cirrhosis, or recurrence in patients with presumed cure of hepatocellular carcinoma. In view of the potential clinical implications, this controversy calls for a thorough and expeditious consideration of the hypothetical oncogenic activity of novel HCV drugs.
