Enveloped viruses distinct from HBV induce dissemination of hepatitis D virus in vivo

Abstract

Hepatitis D virus (HDV) relies on a helper virus to package and transmit its ribonucleoprotein (RNP). Here, Perez-Vargas et al. show that HDV can use envelope proteins from HBV-unrelated viruses, including HCV and flaviviruses, to propagate in vitro and in humanized mice.
