A team of researchers from Spain, the U.S. and the U.K. has genetically modified a strain of rice to produce HIV-neutralizing proteins. In their paper published in the Proceedings of the National Academy of Sciences, the group describes the technique by which they modified the rice and how it might be used to prevent HIV infections.

Medical scientists have made great strides in treating people infected with HIV—death rates from infections have plummeted, especially in the developed parts of the world. Scientists have also put in a lot of time and effort to develop a vaccine against the virus, but thus far, have come up empty. In the meantime, oral medications have been developed that can stave off an infection for a short period of time. But as the researchers with this new effort note, such medications are not generally available in third world countries. To help those at risk, they have been hard at work developing a strain of rice that has the same HIV-neutralizing proteins as the oral medications. Once grown, the rice produces seeds that can be processed on-site to make a topical cream containing the proteins—the cream can then be applied to the skin to allow the proteins to enter the body.
