On the Host Side of the Hepatitis E Virus Life Cycle

Abstract: Hepatitis E virus (HEV) infection is one of the most common causes of acute hepatitis in the world. HEV is an enterically transmitted positive-strand RNA virus found as a non-enveloped particle in bile as well as stool and as a quasi-enveloped particle in blood. Current understanding of the molecular mechanisms and host factors involved in productive HEV infection is incomplete, but recently developed model systems have facilitated rapid progress in this area. Here, we provide an overview of the HEV life cycle… Show more

“…Subgenomic RNA acts as a mRNA for the translation of ORF2 and ORF3 proteins. Translation of the capsid proteins and phosphoproteins occurs on the ribosomes of the host cell [ 1 , 19 , 23 , 24 ]. The next step is to assemble the virus and release the newly produced virions.…”

“…HEV appears as a non-enveloped particle in the feces and as a quasi- enveloped particle in serum and cell culture supernatant [ 9 ]. The genome consists of a 5′-capped and 3′-polyadenylated positive-oriented single-stranded RNA, which contains three open reading frames (ORFs) [ 10 , 11 ].…”
