Targeting amyloid to stop HIV

Scientists have created a substance that targets amyloid structures in semen and weakens HIV's ability to infect the body's immune cells. The experimental compound makes it harder for HIV particles to stick to human immune cells, offering a new lead in developing a microbicide to prevent HIV transmission.
