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 ...

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 ...

There is a precise and predictable relationship between the diameter of an axon and the thickness of the myelin that surrounds it. Writing in Science, Michailov, Sereda and colleagues describe ...

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 cells transmit their signals to other nerve cells via their processes (axons). An insulating sheath spirally wrapped around the axons increases the speed of the electrical impulses enormously.

Researchers have found that Schwann cells, a special type of cells are capable of generating protective myelin sheath covers for the nerves at rates higher than earlier believed. Senior author Dr.

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 ...

This is a preview. Log in through your library . Abstract In rat sciatic nerves, a small bundle of fibers was identified in which myelin sheaths were absent at birth, appeared within 3 days, and grew ...

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, ...

A sponge-like implant in mice has helped guide a treatment that slowed or stopped a degenerative condition similar to multiple sclerosis in humans. It has also given University of Michigan researchers ...
