Big breakthrough: Research team claims to have found cure for Zika infection

A team of researchers have identified a potential target of the Zika virus, which could lead to finding a cure for the dreaded infection.

We could soon have a cure for the Zika infection as a team of researchers has identified a potential target. New research provides insights into why infection with Zika virus after birth generally causes only mild symptoms, whereas devastating foetal malformations can develop when infection occurs during pregnancy.

Healthy people are protected by antiviral factors of our innate immune system. Investigators have now shown that reducing levels of one antiviral factor called interferon-induced transmembrane protein 3 (IFITM3) makes cultured cells highly sensitive to Zika virus infection. The team found that IFITM3 normally stops multiplication of the virus in human cells at an early step, preventing the infected cells from “implosive” cell death. Therefore, drugs that block this cell death pathway might be helpful for preventing the effects of Zika virus infection during pregnancy.

“We describe a striking succession of events that may lead to the death of cells infected with Zika virus. Hopefully, the cells are equipped with antiviral gatekeepers that allow the host to control the infection,” said senior author Olivier Schwartz. The study appears in the EMBO Journal.
