Scratch no more: Gene for itch sensation discovered
...ing itchiness and providing relief for chronic and severe
itching. The "itch gene" is GRPR (gastrin-releasing peptide receptor), which codes for a receptor found in a very small population of spinal cord nerve cells where pain and itch signals are transmitted from the skin to the brain. The researchers, le...
Brain inflammation may be friend, not foe, for Alzheimer's patients
...ty, producing side effects such as encephalitis or severe
brain inflammation in people with Alzheimer’s. “The potential to treat Alzheimer’s disease by modulating the immune system is tremendous and is an area that has not been fully explored,” said O’Banion. “That said, people have to remember that the ...

In mice, drug protects against diabetes and atherosclerosis
...diet for eight weeks, at which time they developed severe
atherosclerosis. Then they were started on the drug to determine whether the drug could halt or reverse the disease process. In both experiments, the drug treatment reduced the size of fatty plaques in the animals' aortas by more than 50 percent c...
Researchers shed light on shrinking of chromosomes

diseases including cancer can arise. But so far we know only little about condensation, a process crucial to the successful separation of chromosomes. Using powerful microscopes, researchers led by Jan Ellenberg at EMBL looked at living mammalian cel...

threat to plant health or to plant products. Although direct losses from potato wart may be insignificant when first detected, indirect economic losses resulting from zero-tolerance regulations for potato wart can be devastating to growers. Indir...
Weizmann Institute scientists develop a general 'control switch' for protein activity

diseases with genetically engineered proteins, and to control these proteins’ activity levels in a precise manner by giving appropriate doses of the drug. Another potential future application is in agricultural genetic engineering. The method might m...
Fat fish put obesity on the hook

obesity in humans. The genetic change blocks the activity of a receptor, the melanocortin-4 receptor, which is at the heart of a “device” in our brains called the “adipostat.” The adipostat regulates body weight homeostatically, like the thermostat ...
Researchers use MRI to predict recovery after spinal cord injury
