In stunning new science, a research team at the University of Lleida, Spain and the IrsiCaixa AIDS Research Institute in Barcelona have developed a variety of transgenic rice that can be used to produce a topical medication to prevent HIV infection.
The idea behind this type of research is that these modified plants are essentially a delivery mechanism for medical compounds. Once the initial investment to develop thevariety is achieved, costs to scale-up and produce useful medication are relatively low. Plus, medications produced this way may require less processing and manufacturing – the plant does that work for you.
In this case, the transgenic rice produces three key Fernández, 2018). The medication is administered by producing a simple topical cream from the seed of the modified rice plants. This cream is than applied to the skin, which absorbs the target .that neutralizes HIV in the body by binding to on the virus, blocking them from interacting with a patient’s cells and preventing infection (
One of the most interesting developments seemed to surprise the researchers (it’s even in the title of the PNAS article about the study – “Unexpected synergistic HIV neutralization by a triple microbicide produced in rice endosperm”). They observed that the HIV produced by the transgenic rice were actually even more effective than those produced using standard methods, yet another example of an unintended consequence, if a positive one for once.
