Enabling nerve regeneration means evicting the cleanup crew

02-28-2007 · EurekAlert!

Macrophages are the immune cells that engulf and destroy the debris of damaged tissue to enable the healing process to begin. Their presence at the scene of damage is critical, but once their task is complete, it is just as critical that macrophages exit rapidly, ending the inflammatory process and making way for regrowth. In fact, the continued presence of macrophages could damage tissue, compromising repair.

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.

Children with gene show reduced cognitive function
11-05-2007 · EurekAlert!
Children possessing a gene known to increase Alzheimer's disease risk already show signs of reduced cognitive function, an Oregon Health & Science University study has found. Scientists discovered that 7- to 10-year-olds with a member of a family of genes implicated in development, nerve cell regeneration and neuroprotection display reduced spatial learning and memory, associated with later-life cognitive impairments. This suggests brain changes predisposing a person to Alzheimer's might occur much sooner than previously thought.

Associative memory -- Learning at all levels
03-14-2007 · EurekAlert!
"Green" means "go," but what does "red" mean? Just about everybody says "stop" since we all have learned to imbue certain colors with meaning (or we would be road kill by now). Long thought to be limited to higher levels of information processing, researchers at the Salk Institute for Biological Studies successfully traced this type of associative learning to early stages of the visual processing pathway.

Nanomedicine opens the way for nerve cell regeneration
05-20-2007 · EurekAlert!
The ability to regenerate nerve cells in the body could reduce the effects of trauma and disease in a dramatic way. In two presentations at the NSTI Nanotech 2007 Conference, researchers describe the use of nanotechnology to enhance the regeneration of nerve cells.

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.

Bone marrow cell transplants help nerve regeneration
12-04-2007 · EurekAlert!
Researchers inserted bone marrow-derived cells (BMCs) into 15mm silicon tubes and subsequently implanted into animal models at sites intended for nerve regeneration. When the BMCs were nourished with bioengineered additives -- such as growth factors and cell adhesion molecules -- the BMCs differentiated into cells with characteristics of Schwann cells -- a variety of neural cell providing insulating myelin around the axons of peripheral nerve cells. The work represents a further step in developing artificial nerves.

Medicalize me: Experts look at how our perceptions of illness are shaped
02-22-2007 · EurekAlert!
Do prescription drug ads make people think they're sick when they're not, or create "disease" out of thin air? Does the "empowered patient" movement mean that doctors have lost some of their professional clout when it comes to making diagnoses and prescribing treatment? These questions and more are the focus of a set of probing essays in The Lancet, all addressing the topic of "medicalization" and what it means in modern society.

Salk scientists identify key nerve navigation pathway
11-21-2007 · EurekAlert!
Newly-launched nerve cells in a growing embryo must chart their course to distant destinations, and many of the means they use to navigate have yet to surface. Scientists at the Salk Institute for Biological Studies have recovered a key signal that guides motor neurons -- the nascent cells that extend from the spinal cord and must find their way down the length of limbs such as arms, wings and legs.
