Mouse models show that myelin dysfunction and associated inflammation increase with age, which can promote amyloid-β deposition and therefore risk of developing Alzheimer’s disease.

Resident microglia in the central nervous system are identified as the specific macrophage population that regulates myelin growth and integrity.

APOE4 impairs myelination via cholesterol dysregulation in oligodendrocytes
APOE4 is associated with widespread gene expression changes across all cell types of the human brain, altered cholesterol homeostasis and transport signalling pathways, and decreased myelination in the brain.

Niche stiffness underlies the ageing of central nervous system progenitor cells
Aged progenitor cells in the rat central nervous system can be made to behave as young cells by reducing the stiffness of the tissue microenvironment, or by inhibiting the mechanosensitive protein PIEZO1.

Altered human oligodendrocyte heterogeneity in multiple sclerosis
Single-nucleus RNA sequencing analysis identifies different subclusters of oligodendroglia in white matter from individuals with multiple sclerosis compared with controls, and these differences may be important for understanding disease progression.

Dynamics of oligodendrocyte generation in multiple sclerosis
There are no new oligodendrocytes in potentially remyelinated multiple sclerosis shadow plaques, although oligodendrocyte generation is increased in the normal appearing white matter of patients with aggressive disease, informing the development of new therapies.

Proton-gated Ca2+-permeable TRP channels damage myelin in conditions mimicking ischaemia
Ischaemia damages nerve myelin by depriving neurons and their myelinating oligodendrocytes of oxygen and glucose; here it is shown that ischaemic damage is caused through the H+-dependent activation of TRPA1 channels, and not via glutamate receptors of the NMDA type, as previously thought, providing a new mechanism and promising therapeutic targets for diseases as diverse and prevalent as cerebral palsy, spinal cord injury, stroke and multiple sclerosis.

Intranasal epidermal growth factor treatment rescues neonatal brain injury
Diffuse white matter injury is common in very preterm infants; here, enhanced epidermal growth factor receptor signalling in oligodendrocyte precursor cells in a mouse model of such injury is shown to increase cellular and functional recovery.

Glycolytic oligodendrocytes maintain myelin and long-term axonal integrity
After myelination, oligodendrocytes are able to survive without mitochondrial respiration, suggesting that they can switch to aerobic glycolysis and release lactate.
