Infectious genotype 1a, 1b, 2a, 2b, 3a, 5a, 6a and 7a hepatitis C virus lacking the hypervariable region 1 (HVR1): Patent #: 8,846,891
Research output: Patent
The present inventors used the previously developed H77/JFH 1.sub.T27OOC,A4O8OT (1a/2a), J4/JFH .sub.1T2996C,A4827T,.DELTA.HVRI (1b/2a), J6/JFH .sub.1.DELTA.HVRI (2a/2a), J8/JFH 1.sub..DELTA.HVRI (2b/2a), S52/JFH 1.sub.T27i8G,.tau.7i6oc (3a/2a), SA13/JFH 1.sub.C34O5G,A3696G (5a/2a) and HK6a/JFH 1T.sub.1389c,A1590G (6a/2a) constructs for the deletion of Hypervariable Region 1 (HVR1) to construct viable, JFH 1 (genotype 2a) based, genomes. The present inventors serially passaged the viruses in cell culture obtaining relatively high HCV RNA titers and infectivity titers. Sequence analysis of the viruses identified mutations adapting H77/JFH 1.sub.T27OOC,A4O8OT,.DELTA.HVR1 (1a/2a), J8/JFH .sub.1.DELTA.HVR1 (2b/2a), S52/JFH 1.sub.T2718G,T716OC,.DELTA.HVR1 (3a/2a) and J4/JFH 1.sub.T2996C,A4827T,.DELTA.HVR1 (1b/2a) to the HVR1 deletion.
