Results may provide new strategy to prevent amputations Blood vessels and supporting cells appear to be pivotal partners in repairing nerves ravaged by diabetic neuropathy, and nurturing their partnership with nerve cells might make the difference between success and failure in experimental efforts to regrow damaged nerves, Johns Hopkins researchers report in a new study. About 20 percent of diabetics experience neuropathy, a painful tingling, burning or numbness in the hands and feet that...

(Ivanhoe Newswire)--Feelings of painful tingling, burning, and numbness in the hands and feet can be reflective of major nerve damage. About twenty percent of diabetics experience these symptoms, know as neuropathy, which can sometimes lead to infections and amputations of the toes, fingers, hands, and feet. However, in a recent study conducted at Johns Hopkins, blood vessels and supporting cells appeared to be pivotal partners in repairing nerves damaged by diabetic neuropathy. Current...

New information has come to light explaining how injured skin cells and touch-sensing nerve fibers coordinate their regeneration during wound healing. UCLA researchers Sandra Rieger and Alvaro Sagasti found that a chemical signal released by wounded skin cells promotes the regeneration of sensory fibers, thus helping to ensure that touch sensation is restored to healing skin. They discovered that the reactive oxygen species hydrogen peroxide, which is found at high concentrations at wounds,...

Compounds helped nerve extensions re-grow faster in mouse studies Drugs already in development to treat Alzheimer's disease may eventually be tapped for a different purpose altogether: re-growing the ends of injured nerves to relieve pain and paralysis. According to a new Johns Hopkins study, experimental compounds originally designed to combat a protein that builds up in Alzheimer's-addled brains appear to make crushed or cut nerve endings grow back significantly faster, a potential boon for...

Research into how the brain transmits messages to other parts of the body could improve understanding of disorders such as epilepsy, dementia, multiple sclerosis and stroke Research into how the brain transmits messages to other parts of the body could improve understanding of disorders such as epilepsy, dementia, multiple sclerosis and stroke. Scientists at the University of Edinburgh have identified a protein crucial for maintaining the health and function of the segment of nerve fibres...

The human brain consists of approximately one hundred billion nerve cells. Each of these cells needs to connect to specific other cells during the brain's development in order to form a fully functional organism. Yet how does a nerve cell know where it should grow and which cells to contact? Scientists of the Max Planck Institute of Neurobiology in Martinsried have now shown that growing nerve cells realize when they've reached their target area in the fly brain thanks to the interaction of...

New research using a mouse model of the motor neuron disease spinal muscular atrophy (SMA) reveals an abnormality in the way that sensory information is relayed to motor neurons in the spinal cord. Importantly, this disruption in communication occurs very early in disease progression and precedes the neuronal death and muscle weakness that are the hallmark of the disease. The study, published by Cell Press in the February 10 issue of the journal Neuron, suggests that therapeutic strategies...

Accidental damage to thin or buried nerves during surgery can have severe consequences, from chronic pain to permanent paralysis. Scientists at the University of California, San Diego School of Medicine may have found a remedy: injectable fluorescent peptides that cause hard-to-see peripheral nerves to glow, alerting surgeons to their location even before the nerves are encountered. The findings are published in the Feb. 6 advance online edition of the journal Nature Biotechnology. Nerve...

This finding has particular importance because several neurodevelopmental disorders have recently been linked to genetic mutations in the complex developmental cascade containing Erk and its sister proteins. Researchers at the University of North Carolina at Chapel Hill have pinpointed a crucial function for a key player in the development of the nervous system. They found that this player "“ a protein called Erk "“ is necessary for nerve fibers to be wrapped with an insulating...
