Abstract:
Vasoactive intestinal polypeptide-like immunoreactive (VIP-LIR) astrocytes were found in the subcortical white matter of the human forebrain parietal lobe. Astrocytes expressing VIP-LIR represented a minority (0.97%) of the GFAP-stained astrocyte population in the white matter. The close anatomical relationship between the VIP-LIR astrocyte bodies and processes and the brain vasculature strongly suggests that they may play a role in the local control of blood flow and of the barrier properties of the vessel walls.
