A versatile transreplication-based system to identify cellular proteins involved in geminivirus replication.

abstract：UNLABELLED:Hepatitis C virus (HCV) is a major cause of chronic hepatitis, liver cirrhosis, and hepatocellular carcinoma in humans. We showed previously that HCV induces autophagy for viral persistence by preventing the innate immune response. Knockdown of autophagy reduces extracellular HCV release, although the precis...
