Proof-of-principle study provides hope for stimulating remyelination Scientists at Joslin Diabetes Center, Harvard University, and the University of Cambridge have found that the age-related impairment of the body's ability to replace protective myelin sheaths, which normally surround nerve fibers and allow them to send signals properly, may be reversible, offering new hope that therapeutic strategies aimed at restoring efficient regeneration can be effective in the central nervous system...

New laboratory approach could aid brain recovery, TAU research finds In humans, active periods of the debilitating disease Multiple Sclerosis (MS) can last for mere minutes or extend to weeks at a time. They're caused by lesions in the brain that develop, partly heal, and then recur. Research into a cure has been difficult, because to date scientists have not been able to replicate these brain recurring symptoms in laboratory mice. That's frustrating because these lab animals, known as...

Mayo Clinic researchers have identified critical steps leading to myelin destruction in neuromyelitis optica (NMO), a debilitating neurological disease that is commonly misdiagnosed as multiple sclerosis (MS). The findings could lead to better care for the thousands of patients around the world with NMO. The paper was published in the journal, Proceedings of the National Academy of Sciences, USA. NMO is an inflammatory autoimmune disease of the central nervous system that damages the optic...

Findings suggest new treatments to limit damage from stroke, very premature birth New research released today demonstrates the brain's remarkable capacity to repair itself. The animal studies, which propose ways to prevent or limit damage after blood and oxygen deprivation and blood clots, were presented at Neuroscience 2011, the Society for Neuroscience's annual meeting and the world's largest source of emerging news about brain science and health. Stroke is the number one cause of...

Beneficial intestinal bacteria can activate immune cells and trigger the overreaction of the immune system Multiple sclerosis is caused by a combination of genetic and environmental factors. For a long time, pathogens were believed to be such external influences. According to scientists from the Max Planck Institute of Neurobiology in Martinsried, however, it is apparently not  harmful bacteria that trigger multiple sclerosis, but beneficial ones — specifically, the natural...

Scientists have improved upon their own previous world-best efforts to pluck out just the right stem cells to address the brain problem at the core of multiple sclerosis and a large number of rare, fatal children´s diseases. Details of how scientists isolated and directed stem cells from the human brain to become oligodendrocytes — the type of brain cell that makes myelin, a crucial fatty material that coats neurons and allows them to signal effectively — were published...

Study findings indicate a key step in the generation of white matter and understanding developmental disabilities Through the identification of a gene's impact on a signaling pathway, scientists at Children's National Medical Center continue to make progress in understanding the mechanics of a key brain developmental process: growth and repair of white matter, known as myelination. The study, published online in the September 2011 online edition of The Journal of Neuroscience, identified...

Process paves way for research, possible treatments of multiple sclerosis and more Scientists at Case Western Reserve University School of Medicine found a way to rapidly produce pure populations of cells that grow into the protective myelin coating on nerves in mice. Their process opens a door to research and potential treatments for multiple sclerosis, cerebral palsy and other demyelinating diseases afflicting millions of people worldwide. The findings will be published in the online...

A new imaging technique could help doctors and researchers more accurately assess the extent of nerve damage and healing in a live patient. Researchers at Laval University in Québec and Harvard Medical School in Boston aimed lasers at rats' damaged sciatic nerves to create images of the individual neurons' insulating sheath called myelin. Physical trauma, repetitive stress, bacterial infections, genetic mutations, and neurodegenerative disorders such as multiple sclerosis can all...

Narcolepsy is a rare disorder characterized by an excessive urge to sleep at inappropriate times and places. Narcoleptics are also often subject to "cataplexy," a sudden muscle weakness that is triggered by strong emotions. Although most cases of narcolepsy are thought to be caused by complex mechanisms, a small percentage of cases are associated with unidentified inherited mutations. Now, a new study published by Cell Press on September 8th in the American Journal of Human Genetics uncovers...
