myelin

The APOE4 variant causes cholesterol buildup in the cells that make protective fatty sheaths for neurons, possibly helping explain its role in neurodegeneration.

A study shows that a molecule produced by intestinal microbes can enter the brain and that its presence is also associated with altered brain connectivity.

A mouse model of autism and postmortem brains of autistic individuals showed a lack of mature oligodendrocytes and less myelination than controls.

In children’s brain scans, scientists uncovered signs of multiple sclerosis before the kids showed any symptoms of the disease.

Snail not extinct after all; results too good to be true?; mice need myelin production for motor learning; keeping the brain young; the evolution of archaea

The production of new myelin in the brain—a function of non-neuronal glial cells—may be necessary for motor learning, a mouse study shows.

New oligodendrocytes in the adult mouse brain appear to remodel existing myelin sheaths, which may fine-tune the speed of nerve impulses.

In a Phase I trial, researchers show that neural stem cells transplanted into humans can differentiate and begin producing myelin.
