RESUMEN
Flaviviruses are a class of positive-strand RNA viruses mainly transmitted by arthropods, which can cause high mortality and morbidity worldwide. At present, there is no specific therapy. Therapeutic antibodies bring hope for the treatment of flavivirus infection, but the antibody-dependent enhancement (ADE) effect induced by flavivirus infection can lead to disease progression. The ideal therapeutic antibodies against flaviviruses should not only treat flavivirus infection, but also avoid the harm caused by ADE. Therefore, researchers have optimized some of the antibodies to seek the best therapeutic antibodies. This review briefly described the research progress and mechanism of therapeutic antibodies against flaviviruses as well as some strategies to reduce the ADE effect induced by the therapeutic antibodies.
