"Unveiling the Neuroprotective Power of Astrocyte Reactivity: The Molecular Switch"
Researchers have discovered a molecular switch that regulates the reactivity of astrocytes, a type of brain cell, which can have neurotoxic or neuroprotective effects on the central nervous system. The study found that injured white matter astrocytes can differentiate into two distinct reactive populations, with neuroprotective astrocytes inhibiting microglial activation and promoting cell survival. By targeting this molecular switch, it may be possible to develop new treatments for conditions such as glaucoma and optic neuropathies.
