Yeast discovery gives insight into familial dysautonomia

... The discovery is important for FD because neurons direct new growth to a tip of the cell. "Without directional growth, neurons can't reach their intended targets, and if they can't reach their targets, they can't make synapses [connections between neurons]," says Collins. Collins suspects that the neurolo...

Researchers identify potential therapeutic target for Huntington's disease

...roglial cells. Since inhibiting KMO activity has a direct effect on toxicity of the mutant protein associated with Huntington's, that could mean microgial cells are home to an important step in progression of the disease. Huntington's affects an estimated 30,000 people in the United States. It is characteri...

Elephant seal pups suffer from ocean warming

...elephant seal pup decreases. Weaning weights are a direct indicator of food availability to mother seals during their pregnancy. Because their prey has migrated to colder waters, female seals have to swim further and spend more time searching for food. As a result, they gain less body mass while pregnant an...

Chemokines orchestrate more than migration for immune cells

.... Chemokines are molecules that have been shown to direct the migration of DCs and recent research has indicated that they may also play a role in DC maturation. Dr. Martin F. Bachman from Cytos Biotechnology in Switzerland and colleagues were interested in identifying new proteins that might indirectly go...

The program will draw on faculty from five Medical School departments: surgery, anatomy, pediatrics, pathology and radiology. Importantly, it brings the basic science of stem cells -- where most work to date has been accomplished --...
