Myelin integrity is increasingly recognised as a critical factor in Alzheimer’s disease pathogenesis. In transgenic mouse models, structural defects in the myelin sheath emerge with advancing age and ...

Researchers found that greater age-related cognitive decline was associated with more dysfunctional oligodendrocytes, reduced ...

In the central nervous system of humans and all other mammals, a vital insulating sheath composed of lipids and proteins around nerve fibers helps speed the electrical signals or nerve impulses that ...

The study covered in this summary was published in medRxiv.org as a preprint and has not yet been peer reviewed. Tau protein levels are lower in more highly myelinated cortical regions. Tau spreading ...

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 ...

As the brain ages, the insulating myelin sheath around axons begins to degrade. Could this white-matter degeneration trigger Alzheimer’s disease? In a preprint on bioRxiv, researchers led by Constanze ...

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.

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.

Devaux and Gow demonstrate how a tight junction protein called claudin 11 makes the neuronal myelin sheath a snug fit. The study will be published in the December 1, 2008 issue of the Journal of Cell ...

In long-lived animals, renewed but thin myelin sheaths are enough to restore the impaired nervous system and can do so for years after the onset of disease, scientists have discovered. In the central ...

MADISON, Wisconsin - In the central nervous system of humans and all other mammals, a vital insulating sheath composed of lipids and proteins around nerve fibers helps speed the electrical signals or ...
