Molecular imaging is redefining in vivo characterization of multiple sclerosis, a demyelinating disease with complex and heterogeneous clinical profiles. Recent advances in PET tracers enable more ...

Nerve fibers are surrounded by a myelin sheath. Scientists at the Technical University of Munich (TUM) have now made the first-ever "live" observations of how this protective layer is formed. The team ...

Researchers have found that new myelin-making cells are constantly being made in the brain and spinal cord, even in the ...

Researchers have demonstrated that enhancing myelin renewal in the brains of transgenic APP/PS1 mouse models of Alzheimer's disease (AD) can improve their task-related hippocampal activity. "To the ...

In a new study, mice bearing a gene deletion associated with autism spectrum disorder (ASD) showed evidence of slower cognition. Another finding: cells that make myelin, a sheath around nerves 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The study covered in this summary was published in medRxiv.org as a preprint and has not yet been peer reviewed.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 ...

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 ...

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 ...

Myelin, a sheath of insulation around nerves that enables electrical impulses to efficiently travel through the central nervous system, is diminished in mice that have a gene deletion associated with ...
