Annotation rationales
Astrocytes are central-nervous-system glia that ensheath synapses and blood vessels and maintain extracellular ion, water and neurotransmitter balance.
Functional implications
They support neurons metabolically, clear glutamate, contribute to the blood–brain barrier and coordinate inflammatory and repair responses after neural injury.
