Stem cells taken from the brain of a 13-year-old girl were transplanted into newborn mice and developed into a variety of brain cells almost identical to the animals' own — a procedure that someday could be used to replace the misfiring cells in some epilepsy patients, the researchers said.

Metformin, a drug used in type 2-diabetes might have the potential to also act against Alzheimer's disease. This has been shown in a study from scientists of the German Center for Neurodegenerative Diseases (DZNE), the University of Dundee and the Max-Planck-Institute for Molecular Genetics.

An old pinworm medicine is a new lead in the search for compounds that block a signaling pathway implicated in colon cancer. The findings, reported by Vanderbilt University Medical Center researchers in the November issue of Nature Chemical Biology, suggest a fresh approach for developing therapeutics that target the pathway.

New animal research has identified factors, such as the stress response and immune system, that may play important roles in depression. Scientists have also found that the regulation of nerve cell signals influences depression in animals, and that new drug combinations may more effectively treat it. The findings were presented at Neuroscience 2010, the annual meeting of the Society for Neuroscience and the world's largest source of emerging news on brain science and health.

A new study by Greek researchers suggests that the biologic drug bortezomib (Velcade), a proteasome inhibitor used to treat multiple myeloma (bone marrow cancer), may represent a promising treatment for rheumatoid arthritis (RA).

A molecular pathway within the brain’s reward circuitry appears to contribute to alcohol abuse, according to laboratory mouse research supported by the National Institute on Alcohol Abuse and Alcoholism (NIAAA), part of the National Institutes of Health (NIH). The findings, published online today in Proceedings of the National Academy of Sciences, also provide evidence that the pathway may be a promising new target for the treatment of alcohol problems.

University scientists are using a seemingly unlikely animal to study development, cell function and the effects of debilitating human diseases. Ninety percent of zebrafish's amino acids are in the same order as a human's. Because of these similarities, zebrafish make excellent model organisms for research on human diseases.

At Sanford-Burnham Medical Research Institute (Sanford-Burnham), a team led by Sean Oldham, Ph.D., and Rolf Bodmer, Ph.D., recently created a simple model to link high-fat diet, obesity and heart dysfunction. Using fruit flies, they discovered that a protein called TOR influences fat accumulation in the heart.

Scientists at the National Institutes of Health have redefined the roles of several cytokines involved in the generation of immune cells implicated in severe autoimmune diseases. The study in mice showed that development of Th17 immune cells can occur without the presence of transforming growth factor (TGF)-beta, a mediator thought to be required for Th17 cell development.

Type 1 diabetes (T1D), formerly known as juvenile diabetes, is a multifactorial disease of complex etiology characterized by the autoimmune destruction of pancreatic beta cells. In addition to genetic susceptibility, it is generally accepted that environmental factors play important roles in triggering disease, with virus infection having perhaps the strongest association.
