In this study the role of anti-flavivirus antibodies during antibody-dependent enhancement of dengue virus (DENV) infection was characterized by using FcγR-expressing cells. Infection-enhancement antibody enhances dengue virus (DENV) replication in FcγR-expressing cells, contributing to high levels of viral replication during secondary infection; a prelude of severe DENV illness. The neutralizing and infection-enhancement activity of antibodies after dengue virus (DENV) infection, Japanese encephalitis virus (JEV) infection and JE vaccination was determined in this study. Using FcγR-expressing cells, serum samples from the early phase of DENV infection exhibited ADE activity but serum samples from late phase of DENV infection exhibited DENV neutralizing activity. Serum sample from a JEV patient exhibited ADE activity during the late phase of JEV infection. Additionally, serum samples from JEV vaccinees exhibited DENV cross-reactive IgG antibodies after JEV vaccination, but neutralizing activity to DENV was absent. The results suggest that other than DENV, flavivirus infection and vaccination also induce cross-reactive antibodies to DENV but cross-neutralizing activity may be low or absent, implying a role of these anti-flavivirus antibodies during DENV infection.
