Mutations across murine hepatitis virus nsp4 alter virus fitness and membrane modifications.
UNLABELLED A common feature of infection by positive-sense RNA virus is the modification of host cell cytoplasmic membranes that serve as sites of viral RNA synthesis. Coronaviruses induce double-membrane vesicles (DMVs), but the role of DMVs in replication and virus fitness remains unclear. Coronaviruses encode 16 nonstructural proteins (nsps), three of which, nsp3, nsp4, and nsp6, are necessa...
متن کاملGenetic analysis of Murine hepatitis virus nsp4 in virus replication.
Coronavirus replicase polyproteins are translated from the genomic positive-strand RNA and are proteolytically processed by three viral proteases to yield 16 mature nonstructural proteins (nsp1 to nsp16). nsp4 contains four predicted transmembrane-spanning regions (TM1, -2, -3, and -4), demonstrates characteristics of an integral membrane protein, and is thought to be essential for the formatio...

متن کاملPrevalence of Hepatitis B virus, Hepatitis C virus and human immunodeficiency virus infections among patients candidate for orthopedic trauma surgeries
Background: Infectious diseases are major public health problems, among which blood-borne ones are the most important infections. Patients who undergo orthopedic surgery are at higher risk of transmitting infectious diseases from and to others, due to repeated blood examinations and injection, drains secretion and receiving blood products. Accordingly, in this study we determined prevalence of ...
متن کاملHepatitis C Virus and Vaccine Development
The prevalence of Hepatitis C virus (HCV) is approximately 3% around the world. This virus causes chronic hepatitis, liver cirrhosis and hepatocellular carcinoma. The effectiveness of interferon-α and ribavirin therapy is about 50% and is associated with significant toxicity and cost. Hence, generating new vaccines or drugs is an obligation. However, there is no vaccine available for clinical u...
