Human Immune Cells (VIDEO)
Caption
A new study from Washington University School of Medicine in St. Louis describes a strategy that could lead to therapies for clearing HIV infection. The video clip shows human immune cells. Those glowing green are infected with HIV. An important HIV protein is normally inactive when inside the cells. But when treated with a drug that activates the protein, tripping a newly identified natural alarm system that can detect the active protein, the infected cells self-destruct. The green glow, which labels the virus, disappears as the cells collapse over several hours in this time-lapse video.
