Electrical activity alters language used by nerve cells

12-19-2006 · EurekAlert!

University of California, San Diego biologists have shown that the chemical language with which neurons communicate depends on the pattern of electrical activity in the developing nervous system. The findings suggest that modification of nerve activity could have potential as a treatment for a wide range of brain disorders.

Researchers discover gene crucial for nerve cell insulation
04-16-2007 · EurekAlert!
Researchers funded by the National Institutes of Health have discovered how a defect in a single master gene disrupts the process by which several genes interact to create myelin, a fatty coating that covers nerve cells and increases the speed and reliability of their electrical signals

Stem cell activity deciphered in the aging brain
12-18-2006 · EurekAlert!
Neurobiologists have discovered why the aging brain produces progressively fewer new nerve cells in its learning and memory center. The scientists said the finding, made in rodents, refutes current ideas on how long crucial "progenitor" stem cells persist in the aging brain.

New HIV vaccine target could solve mutation problem
11-08-2007 · EurekAlert!
While HERV are present in every cell, HIV may disrupt the normal constraints on HERV activity as it alters the cell to produce more HIV. A vaccine could be created containing HERV antigens that would stimulate T-cells targeting cells expressing HERV. Although the vaccine would not produce T-cells capable of recognizing HIV itself, it would evoke immune responses that could still protect people from becoming infected or limit the extent of damage caused by HIV.

A new study of living cells could revolutionize the way we test drugs
04-11-2007 · EurekAlert!
Researchers have made a breakthrough by detecting the electrical equivalent of a living cell’s last gasp. The work takes them a step closer to both seeing the "heartbeat" of a living cell and a new way to test drugs.

Milestone in the regeneration of brain cells
08-20-2007 · EurekAlert!
Neuherberg, 20 Aug. The research group of Prof. Dr. Magdalena Götz at the Institute of Stem Cell Research of the GSF -- National Research Centre for Environment and Health, and the Ludwig Maximilians University, Munich, has achieved an additional step for the potential replacement of damaged brain cells after injury or disease: functional nerve cells can be generated from astroglia, a type of supportive cells in the brain by means of special regulator proteins.

Key Function Of Nervous System Enzyme Found; Impact On Drug Development Against Alzheimer's
09-29-2006 · ScienceDaily
Ever since scientists first elucidated the molecular mechanisms underlying the pathology and loss of nerve cells in Alzheimer's disease, drug companies have been working to develop drugs which will inhibit the outbreak of this severe form of dementia. Now researchers in Munich and Berlin (Germany) have discovered that an enyzme which has a central causal role in Alzheimer's disease happens also to have a key function in the normal development of the nervous system. This enzyme, beta-secretase or BACE1, ensures that nerve fibers (axons) are adequately isolated with sheaths of myelin, enabling rapid conduction of electrical impulses, as well as preventing short-circuits, akin to plastic insulation on electrical wires.

Scientists have discovered a new source of stems cells and have used them to create muscle, bone, fat, blood vessel, nerve and liver cells in the laboratory. The first report showing the isolation of broad potential stem cells from the amniotic fluid that surrounds developing embryos was published today in Nature Biotechnology.

Innovative movies show real-time immune-cell activity within tumors
11-20-2006 · EurekAlert!
Using advanced new microscopy techniques in concert with sophisticated transgenic technologies, scientists have for the first time created three-dimensional, time-lapse movies showing immune cells targeting cancer cells in live tumor tissues. Immune cells called T cells can be seen actively migrating though tissues, making direct contact with tumor cells, and killing them. Insights from this new view of the body's on-board defenses against cancer may open the way for improved immunotherapies to treat the disease.
