Cell-saving drugs may reduce stroke impairment

Long-term brain damage from strokes may be reduced by saving cells that control blood flow, new research shows.

The study found using drugs to save the pericyte cells – which expand and contract to regulate blood flow in capillaries – may reduce lasting blood flow impairment. It was previously believed blood flow was solely controlled by arterioles, blood vessels that branch out from larger arteries and into smaller capillaries.

In a lab setting, researchers identified chemicals that halved pericyte death from a simulated stroke.

Lead researcher David Attwell is hopeful the discovery could help create drugs to prevent the cells dying, and reduce disability caused by stroke.
