Regenerative Astrocytes Repair Brain Damage

Summary: Researchers discovered a previously unknown mechanism through which the adult mammalian brain repairs itself following focal injuries or autoimmune damage. Using two-photon microscopy and longitudinal gene mapping in living…

Rare Brain Cells Offer Clues to Aging and Rejuvenation

Summary: A study reveals how brain cell interactions influence aging, showing that rare cell types either accelerate or slow brain aging. Neural stem cells provide a rejuvenating effect on neighboring…
