Our new paper reveals that chronic active MS lesions feature CD8⺠T cell niches with lipid-laden, inflamed microglia. IFN-γ drives cholesterol buildup, linking dysregulated lipid metabolism to inflammation and meurodeg. Check it out

Single-cell spatial transcriptomic profiling defines a pathogenic inflammatory niche in chronic active multiple sclerosis lesions
Compartmentalized inflammation is a key driver of multiple sclerosis (MS) progression, but the mechanisms sustaining its persistence remain unclear. Aā¦

Adaptor protein complex 2 (AP2) participates in biogenesis and homeostasis of myelin sheaths in the central nervous system
Myelination of CNS axons requires oligodendrocytes to undergo extensive morphological changes by producing large amounts of myelin membrane with defined protein composition and structure. The formatio...

How does aging affect the white matter and what are the consequences for brain function and neurodegenerative disease? Thankful to see this review with Mika Simons now published in a fascinating collection on the science of brain aging

White matter aging and its impact on brain function
Aging leads to a decrease in white matter volume and damage to myelinated axons, contributing to neurodegeneration. Myelin breakdown can trigger inflammation, creating a vicious cycle that causes further damage. Understanding these changes is key to preventing age-related neurodegenerative disease.
