| 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 Posted: 12 Feb 2012 04:27 PM PST 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. |
| How a protein protects cells from HIV infection Posted: 12 Feb 2012 04:25 PM PST A novel discovery reveals a mechanism by which the immune system tries to halt the spread of HIV. Harnessing this mechanism may open up new paths for therapeutic research aimed at slowing the virus' progression to AIDS. |
| A mitosis mystery solved: How chromosomes align perfectly in a dividing cell Posted: 12 Feb 2012 04:25 PM PST Although the process of mitotic cell division has been studied intensely for more than 50 years, researchers have only now solved the mystery of how cells correctly align their chromosomes during symmetric mitosis. |
| Automatic suspension of insulin delivery via insulin pumps reduces hypoglycemia Posted: 09 Feb 2012 10:53 AM PST An automated on/off feature built into insulin pump systems can suspend insulin delivery when it detects low blood glucose levels (via continuous glucose monitoring), significantly reducing the severity and duration of hypoglycemia in individuals with Type 1 diabetes, according to a new study. |
