Like a string of beads, the cholesterol- and lipid-rich myelin sheaths coat and insulate nerve fibres in order to enable fast and efficient impulse transmission. As we all know, a string of beads can ...

Efficient removal of abnormal myelin allows survival of nerve fibers targeted by adaptive immune cells, according to a novel study. Myelin is an insulating sheath around axons -- the processes ...

A new study suggests that restricting calorie intake over a lifetime may slow the biological aging of support cells in the ...

Long-term calorie restriction reshapes the aging brain at the cellular level, maintaining healthier pathways that make it ...

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 ...

Oligodendrocytes may show early immune-like changes in multiple sclerosis (MS), according to findings from a mouse study.

Researchers from the F.M. Kirby Neurobiology Center in the US have discovered a new approach to restore myelin sheaths, the fatty substance that surrounds nerve cells. The findings may be able to aid ...

Multiple sclerosis (MS) is a serious neurological disease that usually causes permanent disability. Approximately 2.9 million people are affected worldwide, 240,000 in Germany alone. The exact cause ...

When lesions develop in myelin disorders such as multiple sclerosis, the cholesterol- and lipid-rich insulating layer around the nerve fibres is lost. In order to prevent permanent damage, the now ...
