Posted: 12 Feb 2012 04:27 PM PST

A protein that protects some of our immune cells from the most common and virulent form of HIV works by starving the virus of the molecular building blocks that it needs to replicate. While researchers hope the work will one day lead to a way to make anti-HIV drugs more effective by increasing their potency against the virus, they're also excited about its implications for our knowledge of other pathogens, such as herpes viruses.

Molecular secrets of ancient Chinese herbal remedy discovered

Researchers have discovered the cellular target for a two-thousand-year-old herbal remedy known as Chang Shan. The bioactive compound, called febrifugine, triggers a stress-response pathway that tells cells to conserve resources and eliminate unnecessary functions, which in turn blocks the production of dangerous, disease-causing immune cells.
