myelin : Definition, Usages, News and More
- n a white fatty substance that forms a medullary sheath around the axis cylinder of some nerve fibers
- Throughout our lives, fresh layers of myelin sheathing are laid down in the brain.
- The white matter is composed of fatty myelin sheaths that encase axons and, like insulation on a wire, make nerve-signal transmissions faster and more efficient.
- Antibodies with a low affinity for myelin-producing cells in the central nervous system may stimulate these cells to divide and develop.

- Early diagnosis and treatment may reduce MS relapses
Multiple sclerosis is a chronic autoimmune disease that disrupts nerve impulses in the central nervous system (brain, optic nerves and spinal cord) by attacking the protective coverings around nerve fibers known as myelin, and often damaging the nerve fibers (axons) themselves. Consequently, it can cause a diverse range of symptoms including numbness, weakness, spasticity, gait disturbances ...

- Multiple sclerosis: Phase 1 trial safely resets patients' immune systems, reduces attack on myelin protein
A phase 1 clinical trial for the first treatment to reset the immune system of multiple sclerosis (MS) patients showed the therapy was safe and dramatically reduced patients' immune systems' reactivity to myelin by 50 to 75 percent. The therapy used billions of patients' own specially processed blood cells to create tolerance to myelin, the insulating layer that forms around nerves. In MS, the ...

After nerve injury, the degenerating myelin downstream from the injury is rapidly cleared in the peripheral, but not the central, nervous system,said Barres. "In fact in an injured human brain or spinal cord, the degenerating myelin just...

This finding is a departure from mainstream thinking about MS and related disorders, where the major focus of research in the past century has been the myelin that insulates nerve fibers, and the cell that manufactures myelin, known as the...
