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 ...

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 ...

Oligodendrocytes are the myelinating cells of the central nervous system (CNS) that constitute about 5–10% of the total glial population (Yeung et al., 2019). Myelin is a lipid-rich substance ...

There has been a growing interest in the role of oligodendrocytes (OLs) and the myelin sheaths they form around axons in cognitive function. Historically, OLs were primarily considered to be involved ...

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 ...

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 ...

Multiple sclerosis is a condition whereby the immune system attacks and destroys myelin – the protective coating of nerve fibers – which triggers movement problems characteristic of the disease. Now, ...

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.
