A team of UNC researchers filed a patent for a potential Zika virus vaccine in late January. No vaccine or treatment exists yet for the Zika virus, which gained notoriety in recent years, particularly during the 2016 summer Olympic Games.
The patent covers specific proteins on the Zika virus that contribute to initiating the body’s immune response. The Zika virus is made up of 180 proteins that form a ball-like structure. The research team, led by professor Ralph Baric and assisted by postdoctoral scholar Jessica Plante, graduate research assistant Jesica Swanstrom and research technician Matthew Begley, discovered that some of these individual proteins can be manipulated in ways to decrease the virus’s effects on the body.
Although the patent is not a vaccine itself, the framework it provides can be used to help develop future vaccines, according to Begley.
The best way to think of the new patent is similar to that of a completed Lego set, he said. The Zika virus’s surface is the finished Lego set, which is made up of many blocks. The patent contains instructions for how to build the final "Lego set" and manipulate the ways in which the “blocks” fit together. By changing the ways in which the “blocks” fit together, researchers can hopefully achieve a better immune response to reduce the spread of the Zika virus and lead to a reduction of symptoms, Begley said.
