What Is a Myelin Sheath? Myelin sheaths are sleeves of fatty tissue that protect your nerve cells. These cells are part of your central nervous system, which carries messages back and forth between ...

Scientists have discovered another molecule that plays an important role in regulating myelin formation in the central nervous system. Myelin promotes the conduction of nerve cell impulses by forming ...

This news release is available in Japanese. Researchers in Japan have revealed the molecular mechanism involved in the process of repair to damage of the myelin sheath. In vertebrates, axons extending ...

Most nerve axons of higher vertebrates are surrounded by a multilayered myelin membrane that is essential for promotion of rapid nerve conduction. A new study genetically uncouples the ...

Nodes of Ranvier are important for rapid, saltatory nerve conduction. Although the molecular constituents of the nodes and paranodes are well established, how they are assembled is still a mystery.

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 ...

Researchers identify a new type of skin-related stem cell in a mouse model study that holds promise for restoring lost myelin in neurodegenerative disorders. Formed from oligodendrocytes, the myelin ...

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 ...
