...reatine (NAA/Cr) ratio, an indicator of neuron and axon integrity, compared to four untreated control patients after one year of treatment. This increase was maintained at two years of follow-up. Additionally, patients treated with COPAXONE? showed a significant 50 percent reduction in relapses compared t...

Stem Cells From Hair Follicle To Repair Nerve Damage

...ggest hair follicle stem cells can promote nervous axon growth and functional recovery after nerve injury, thus offering an opportunity for the clinical treatment of peripheral nerve diseases, said the researchers. The team, including researchers from the Massachusetts Institute of Technology, the Kitasa...

Chemical Signaling Helps Regulate Sensory Map Formation In The Brain

...in graded fashion in the brain and are involved in axon guidance. The A-class ephrins are required for map formation along the anterior-posterior (front-to-back) axis and the B-class for median-lateral (side-to-side) axis. For several years, Zou's lab has been studying a different family of proteins, kn...

Transport of Proteins Unravels the Mystery behind Neurodegenerative Diseases

...mutated protein in SBMA, caused inhibition of fast axon transport by activating an enzyme called JNK that can inhibit these transport proteins. Brady said this is the first proposed mechanism for polyQ diseases that explains why only nerve cells die and why the terminals die before the cell body. The link...

Scientists Coax Nerve Fibers to Regrow After Spinal Cord Injury

...from growing. Schnaar refers to these molecules as axon regeneration inhibitors, or simply ARIs. “Treatments that eliminate ARIs might allow the nerve ends to regain their natural regenerative abilities as they do in the periphery and improve recovery,” says Schnaar. The researchers looked at the bou...

Fines Paid By Speeding Motorists Used in Funding Spinal Cord Injury Research

...ce they've been severed. Giger is an expert on how axon guidance molecules act as a sort of traffic cop in the central nervous system, determining the paths along which nerve cells grow to link up with each other to form vast networks. He has identified molecules that likely play a role in preventing the...

Blame Myelin for Many Neuropsychiatric Disorders

...hat myelin, the sheet of fat that coats a neuron’s axon — a long fiber that conducts the neuron’s electrical impulses — is akin to the wrapping around an electrical wire, protecting and fostering efficient signaling. But the research of UCLA neurology professor George Bartzokis, M.D., has already shown th...

NMNAT Protein Protects Against Nerve Cell Degeneration

...ynapses (the functional connection between a nerve axon and the target cell)," said Bellen. However, late in the development of the eye, the insects in the pupal stage begin to sense light. As the neurons become active, they degenerate rapidly. Within two weeks after birth, there are almost no neurons l...

Myelin basic protein (MBP) is a major component of the myelin sheath and when used as an antigen will induce experimental autoimmune encephalitis (EAE) in mice, which is used as an animal model of human MS. Interestingly, myelin-specific T...
