Some neurological conditions such as multiple sclerosis and cerebral palsy are associated with the inability to repair the chronic destruction of myelin sheaths that surround the core of a nerve fiber and function to speed transmission of nerve impulses. To better understand the failure to remyelinate these nerves in disorders involving loss of these sheaths, researchers at Baylor College of Medicine examined how myelin forms during development. They found that a transcription factor known...

Glial cells pass on metabolites to neurons Around 100 billion neurons in the human brain enable us to think, feel and act. They transmit electrical impulses to remote parts of the brain and body via long nerve fibers known as axons. This communication requires enormous amounts of energy, which the neurons are thought to generate from sugar. Axons are closely associated with glial cells which, on the one hand, surround them with an electrically insulating myelin sheath and, on the other...

Researchers studying multiple sclerosis (MS) have long been looking for the specific molecules in the body that cause lesions in myelin, the fatty, insulating cells that sheathe the nerves. Nearly a decade ago, a group at Mayo Clinic found a new enzyme, called Kallikrein 6, that is present in abundance in MS lesions and blood samples and is associated with inflammation and demyelination in other neurodegenerative diseases. In a study published this month in Brain Pathology, the same group...

Researchers at the Perinatology Research Branch of the National Institutes of Health, located at the Wayne State University School of Medicine and the Detroit Medical Center, have demonstrated that a nanotechnology-based drug treatment in newborn rabbits with cerebral palsy (CP) enabled dramatic improvement of movement disorders and the inflammatory process of the brain that causes many cases of CP. The findings strongly suggest that there may be an opportunity immediately after birth for...

Intravenous immune globulin (IVIg) is an effective treatment for certain disorders of the nerve and muscles, including Guillain-Barré syndrome (GBS) and a form of neuropathy called chronic inflammatory demyelinating polyneuropathy (CIDP), according to a guideline issued by the American Academy of Neurology. The guideline is published in the March 27, 2012, print issue of Neurology®, the medical journal of the American Academy of Neurology. IVIg is a type of immunotherapy...

Millions of adults suffer from the incurable disease multiple sclerosis (MS). It is relatively certain that MS is an autoimmune disease in which the body's own defense cells attack the myelin in the brain and spinal cord. Myelin enwraps the nerve cells and is important for their function of transmitting stimuli as electrical signals. There are numerous unconfirmed hypotheses on the development of MS, one of which has now been refuted by the neuroimmunologists in their current research: The...

(Ivanhoe Newswire)-- Recent studies give hope for patients with the irreversible disease known as MS or multiple sclerosis by possibly reversing the aging effects of the central nervous system. Approximately 100,000 people in the United Kingdom, 400,000 in the United States and several million worldwide are affected by MS. With age our bodies' regenerative abilities decrease. While wrinkles allow us to see visible aging effects of skin many other body tissues are left invisibly aging....
