Potent new anti-HIV proteins found in Australian coral reefs

Last Updated: Wednesday, April 30, 2014, 19:03

Researchers have found a new class of proteins capable of blocking the HIV virus from penetrating T-cells, which has raised hope that the proteins could be adapted for use in gels or sexual lubricants to provide a potent barrier against HIV infection.
