Researchers have identified a cheap, commonly-used compound that, applied vaginally, can stop monkeys being infected with a primate version of HIV. The discovery, by the University of Minnesota, raises hopes of a similar microbicidal treatment to block HIV transmission in humans.
The study - focusing on a compound called glycerol monolaurate (GML) - is published online by the journal Nature. GML is a naturally occurring compound widely used as an antimicrobial and anti-inflammatory agent in food and cosmetics. Crucially, it is also cheap, and is likely to protect against other sexually transmitted infections too.
Lead researcher Dr Ashley Haase said that if GML proved to be effective in blocking HIV it could potentially help to save millions of lives. A majority of cases of HIV worldwide are now contracted vaginally, and in Sub-Saharan Africa, where the pandemic is at its most intense, women account for nearly 60% of new infections.
