Discovery underscores difficulties in developing regenerative spinal cord injury therapies Neuroscientists at the University of California, San Diego School of Medicine have found that removing three key inhibitory molecules from myelin "“ the insulating material that surrounds nerve cell fibers "“ does not significantly boost the ability of injured spinal axons to regenerate and restore themselves to full function. "I think this just shows how incredibly complicated the challenge...

Animal study suggests new target that might help aid recovery for patients with traumatic injuries A protein called fibrinogen that is known to help form blood clots also triggers scar formation in the brain and spinal cord, according to new research in the April 28 issue of the Journal of Neuroscience. Researchers found that fibrinogen carries a dormant factor that activates when it enters the brain after an injury, prompting brain cells to form a scar. Scars in the brain or spinal cord can...

Richard Borgens and his colleagues from the Center for Paralysis Research at the Purdue School of Veterinary Medicine have a strong record of inventing therapies for treating nerve damage. From Ampyra, which improves walking in multiple sclerosis patients to a spinal cord simulator for spinal injury victims, Borgens has had a hand in developing therapies that directly impact patients and their quality of life. Another therapy that is currently undergoing testing is the use of polyethylene...

New research investigating neurological decline in a population of "super healthy" elderly subjects found that the decline in neurological function of the peripheral nervous system attributed to aging may be related to metabolic factors, such as blood sugar levels, even if these factors are within the normal range. In a related study of peripheral nerve function, the same group found that aging affects the nerves of men more than women later in life. The findings imply, the researchers say,...

An electronic device is an accurate technique for locating and avoiding nerves during spinal procedures, suggests a study by Henry Ford Hospital researchers. The issue becomes important for patients as the demand for minimally invasive surgical techniques continues to grow, so does the need for effective methods for monitoring the location of nerves during surgery to avoid damage to them. Mechanomyography (MMG) systems function by measuring the mechanical response of muscle following nerve...

Scientists at the Queensland Brain Institute have uncovered a vital clue into how the brain is wired, which could eventually steer research into nervous system disorders such as Parkinson's disease and cognitive disorders including autism. It's long been known that growing nerve fibres, also known as axons, must make connections in the brain for it to function properly. "During the brain's development, billions of nerve cells send out nerve fibres which have to find the appropriate targets...

The cells regarded as the "gate-keepers" of the barrier between blood circulation and the peripheral nerves have been hard to study and even harder to isolate. However, researchers at Baylor College of Medicine have created a laboratory model that will enable scientists to study a wide variety of diseases affecting peripheral nerves. They describe their model in the January 2010 issue of the Journal of Neuropathology and Experimental Neurology. Specialized vascular system "The barrier is...

Scientists at the Babraham Institute have discovered a novel survival factor whose rapid transport along nerve cells is crucial for keeping them alive. The same factor seems likely to be needed to keep our nerves healthy as we age. These findings, published today in the online, open-access journal PLoS Biology, show that a molecule known as Nmnat2 provides a protective function; in its absence healthy, uninjured nerve cells start to degenerate and boosting levels of Nmnat2 can delay...

New study about 'helper' cells has implications for nerve disorders such as multiple sclerosis Glial cells, which help neurons communicate with each other, can leave the central nervous system and cross into the peripheral nervous system to compensate for missing cells, according to new research in the Dec. 2 issue of The Journal of Neuroscience. The animal study contributes to researchers' basic understanding of how the two nervous systems develop and are maintained, which is essential for...

Researchers have shown how an experimental drug might restore the function of nerves damaged in spinal cord injuries by preventing short circuits caused when tiny "potassium channels" in the fibers are exposed. The chemical compound also might be developed as a treatment for multiple sclerosis. Because nerves usually are not severed in a common type of spinal cord trauma, called "compression" injuries, the drug offers hope as a possible treatment, said Riyi Shi, a professor in Purdue...
