Generation of DelNS1 Influenza Viruses: a Strategy for Optimizing Live Attenuated Influenza Vaccines.

abstract：:Tumor necrosis factor alpha-induced protein 3 (TNFAIP3), also known as A20, is a ubiquitin-editing enzyme capable of ubiquitination or deubiquitination of its target proteins. In this study, we show that hepatitis C virus (HCV) infection could induce the expression of A20 via the activation of the A20 promoter. The in...
