3H12 was reactive with all DENV types, and cross-reacted with these viruses, such as Japanese encephalitis and West Nile viruses. MAb 3H12 exhibited only enhancing activities, which were suppressed by pretreatment of cells with anti-FcγRIIa. Induction of 3H12 in Mochizuki-immunized mice may have implications for dengue vaccine strategies designed to minimize induction of enhancing antibodies in vaccinated humans.
Figure 1 Neutralizing and enhancing activities of DENV-1 MAbs.
Balance between neutralizing and enhancing activities of five DENV-1 MAbs obtained in our assay system using semiadherent K562 cells. C(+), presence of complement; C(−), absence of complement; Ave, average.
A Mouse Monoclonal Antibody against Dengue Virus Type 1 Mochizuki Strain Targeting Envelope Protein Domain II and Displaying Strongly Neutralizing but Not Enhancing Activity
Figure 2 Effect of the IgG subclass or epitope site on the balance of neutralizing activity and enhancing activity.
The balances were compared among four antibodies of different IgG subclasses (IgG1, IgG2a, IgG2b, and IgG3) engineered from 7F4 (closed circles) or 3H12 (open circles) in the absence.
