Figure 1 Analysis of E1E2 of diverse HCV genotypes.
Radiolabeled proteins in the lysate of HEK 293T cells cotransfected with different plasmids as described in A above were immunoprecipitated using a mixture of anti-E2 MAbs AP33 and ALP98. The immune complexes were analyzed by SDS-10% PAGE under reducing conditions. Positions of protein size markers are shown (in kDa).

Figure 2 Lysine residues upstream of the conserved epitope 412-423 are important for mAb AP33 binding.
The binding pattern of mAb 3/11 and AP33 was compared using wild type or mutated patientderived peptides spanning AA region 406-427. Serial dilutions of mAbs were incubated with surface-attached peptides (25 lg/mL), and bound antibodies were detected with a horseradish peroxidase–conjugated antispecies secondary antibody. Peptides were generated with K- or A-substitutions at positions 408 and/or 410 (H77c: K408A, N410K, N410A, and double mutants K408A-N410K and K408A-N410A; LT-P05_VF: T408A, T408K, K410A, and double mutants T408K-K410A and T408A-K410A; CC-P08_VA: A408K, K410A, and double mutant A408KK410A). The resulting peptide sequences are shown and changed AA marked. Dots indicate AA similarity.

Figure 3 mAb AP33 protects humanized mice against an HCV gt1b challenge.
Chimeric animals were challenged with 104 IU of HCV RNA of mLT_P05 without pretreatment (no IgG) or after passive immunization on day 23 with 1 mg of mAb 3/11 or AP33. Plasma HCV-RNA levels (IU/mL) were measured until 8 weeks after viral challenge. Mice that remained noninfected postinoculation are shown as HCV RNA <750 IU/mL (LOQ, dotted line). Animal B338RL died 4 weeks after viral challenge.

This study investigates the role of antibodies targeting the hypervariable region 1 (HVR1) of the hepatitis C virus (HCV) envelope protein in blocking viral infection. The researchers demonstrated that antibodies specific to the HVR1 region could inhibit the interaction between the HCV E2 protein and the SR-B1 receptor, which is crucial for viral entry into host cells. Through experiments with antibodies derived from chronic hepatitis C (CHC) patients and rabbits immunized with HVR1 peptides, the study showed that these antibodies could effectively neutralize multiple HCV genotypes, thereby highlighting the potential of HVR1-targeting antibodies in controlling HCV infections.
Creative Biolabs provided the monoclonal antibody AP33 (Cat# PABX-079) used to block cell-free transmission of HCV in the cell-cell transmission assays. The AP33 antibody was crucial in demonstrating the efficacy of patient-derived IgGs and HVR1-specific antibodies in inhibiting both cell-free and cell-cell transmission of the virus. This contribution was essential for validating the study's findings on the role of HVR1-targeting antibodies in preventing HCV infection and transmission.
