Degeneration of myelinating oligodendrocytes and the resulting breakdown of the myelin sheath are key drivers of neurodegeneration and disability across numerous central nervous system pathologies. Thus, a compelling strategy to preserve neuronal function is to promote endogenous myelin repair by oligodendrocyte precursor cells (OPCs). Extracellular vesicles (EVs) secreted by pro-regenerative microglia have been shown to enhance OPC maturation and remyelination across different experimental m...

Restoring the transport and concentration of vitamin C, which is deficient in the brain cells of Alzheimer's patients, may be important for delaying the onset and progression of the disease.

Astrocyte diversity is greatly influenced by local environmental modulation. Wang et al. report a critical role for astrocytic primary cilia in transmitting local cues that drive the region-specific diversification of astrocytes within the developing mouse brain.
