Astrocytes are critical regulators of CNS function and are proposed to be heterogeneous in the developing brain and spinal cord. Here we identify a population of astrocytes located in the superficial laminae of the spinal dorsal horn (SDH) in adults that is genetically defined by Hes5. In vivo imaging revealed that noxious stimulation by intraplantar capsaicin injection activated Hes5 SDH astrocytes via α-adrenoceptors (α-ARs) through descending noradrenergic signaling from the locus coeruleus.

It also transports iron to ferrochelatase that catalyzes insertion of Fe into protoporphyrin IX. Here, we find that CyaY has the ability to bind heme as well as iron, exhibiting an apparent dissociation constant for heme of 21 ± 6 nM.
