New research reveals that Alzheimer's disease may impair nerve function not by reducing myelin, but by altering the proteins ...

Right next to these gaps are "paranodes," where the myelin sticks tightly to the nerve, helping anchor it in place and organize the nerve for fast, accurate signaling.

Researchers have identified structural abnormalities at the myelin-axon interface in Alzheimer's that may hinder electrical signaling.

Development of myelin sheath along NM axons Formation of nodes requires maturation of myelin sheaths. To clarify their relationship on NM axons, we also examined the development of myelin with an ...

In this theoretical and numerical proof of concept study, we propose a novel dMRI model for the diffusion process within a series of impermeable concentric cylinders separated by infinitesimal gaps ...

The nerve fibers that transmit itch, like those that transmit pain, are not covered by the myelin sheath that encloses most nerves. Perhaps that makes them easier to damage.

Gaps between segments of myelin sheaths (a) are small enough to consider the entire myelin-coated axon as a cylinder (b) with the axon's radius as 𝑎, the entire cylinder's radius as 𝑏, and the ...

Besides providing lipids for the synthesis of myelin sheaths during development, astrocytes, namely those contacting the nodes of Ranvier, were also reported to reversibly modify myelin thickness and ...

A new study shows that an inhibitor called ESI1 could potentially treat multiple sclerosis and other conditions associated with demyelination.

Myelin sheath, a sleeve that protects a part of your nerve cells, and how it's related to multiple sclerosis. Read to learn more about its functions and how to protect it from damage.
