The study identifies astrocyte-secreted CCN1 as a key factor in maintaining neural circuit stability in the adult brain, particularly in the visual cortex, by regulating synaptic maturation, inhibitory neuron development, and oligodendrocyte maturation, thereby restricting plasticity and preserving functional connectivity.

The study reveals that lesion-remote astrocytes (LRAs) in the injured spinal cord adopt distinct molecular states that regulate microglia-mediated white matter repair, primarily through CCN1 secretion, which influences microglial lipid metabolism, debris clearance, and neurological recovery. Loss of astrocyte-derived CCN1 impairs debris clearance and functional recovery, positioning LRAs as key orchestrators in CNS repair processes.
