Dengue Virus Antibodies Enhance Zika Virus Infection

Abstract

Background For decades, human infections with Zika virus (ZIKV), a mosquito-transmitted flavivirus, were sporadic, associated with mild disease, and went underreported since symptoms were similar to other acute febrile diseases endemic in the same regions. Recent reports of severe disease associated with ZIKV, including Guillain-Barre syndrome and severe fetal abnormalities, have greatly heightened awareness. Given its recent history of rapid spread in immune naive populations, it is anticipated that ZIKV will continue to spread in the Americas and globally in regions where competent Aedes mosquito vectors are found. Globally, dengue virus (DENV) is the most common mosquito-transmitted human flavivirus and is both well-established and the source of outbreaks in areas of recent ZIKV introduction. DENV and ZIKV are closely related, resulting in substantial antigenic overlap. Through a mechanism known as antibody-dependent enhancement (ADE), anti-DENV antibodies can enhance the infectivity of DENV for certain classes of immune cells, causing increased viral production that correlates with severe disease outcomes. Similarly, ZIKV has been shown to undergo ADE in response to antibodies generated by other flaviviruses. However, respo...Continue Reading

Antibody-Dependent Enhancement

Antibody-dependent enhancement of viral infection is the entry of virus into host cells mediated by antiviral antibodies interacting with Fc or complement receptors. This has been most extensively observed with the dengue virus. Find the latest research on antibody-dependent enhancement here.
