The myelin sheath is a protective covering that surrounds fibers called axons, which are the long thin projections that extend from the main body of a nerve cell or neuron. This sheath is composed of ...

Nerve fibers are surrounded by a myelin sheath. Scientists have now made the first-ever 'live' observations of how this protective layer is formed. Nerve fibers are surrounded by a myelin sheath.

The disruption of axons—the thread-like part of nerve cells that transmits electrical signals—is associated with Alzheimer’s disease. One way axonal function may be hindered is through damage to the ...

Loss of myelin underlies several disorders of the central nervous system (CNS) in humans, the most well known of which may be multiple sclerosis. Multiple sclerosis affects roughly 2.5 million people ...

A research team led by neurobiologist Professor Claire Jacob has identified an important mechanism that can be used to control the restoration of myelin sheaths following traumatic injury and in ...

Nerve fibers in the brain and spinal cord are wrapped in an insulating sheath known as myelin. For a long time, this barrier, ...

In patients with multiple sclerosis, there is continuous loss of the insulating myelin sheath that wraps around neurons and increases the speed of impulses in the central nervous system. Whenever ...

Multiple sclerosis (MS) is a serious neurological disease that usually causes permanent disability. Approximately 2.9 million people are affected worldwide, 240,000 in Germany alone. The exact cause ...

Researchers at Institute of Science Tokyo have identified laminin-411 and A4G47, a synthetic peptide derived from the E8 domain of laminin-411 protein, as the key factors in the maturation of ...

We are interested in the public dissemination of our research activities. In this section, we aim to explain our research topic in a lay language, reachable for a broad public spectrum and for ...
