Induction of HSP-70 after hyperosmotic opening of the blood-brain barrier in the rat.
The cellular response resulting from breakdown of the blood-brain barrier was evaluated 24 h after hyperosomotic infusion of mannitol into the internal carotid artery in the rat. Heat shock protein (HSP-70), a marker of cellular stress and/or injury, was induced in scattered patches of neurons and glia in regions of barrier breakdown. These findings suggest that osmotically induced breakdown of the blood-brain barrier may result in cell injury.
