A Gene Variant Linked to Alzheimer’s May Disrupt Myelin Production

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

Brain Fluid from Youngsters Gives Old Mice a Memory Boost

Dan Robitzski | May 11, 2022 | 3 min read

A growth factor found in the cerebrospinal fluid of young mice triggered the proliferation of myelin-making cells when injected into the brains of older mice.

Two oligodendrocyte progenitor cells are being generated from adult stem cells nestled on the surface of brain ventricle

Scientists Discover “Gorditas” and Other Novel Brain Cell Types

Amanda Heidt | Jun 10, 2021 | 5 min read

A pool of neural stem cells that ordinarily lies dormant in the brains of adult mice spawns two types of never-before-documented glial cells when artificially reactivated, potentially pointing to a novel mechanism of brain plasticity.
