Brain Cells, works to circulate blood clots?

Researchers discover how small blood vessels to remove blood clots from the brain in rats.

This discovery is expected to help researchers better understand how to treat patients with Alzheimer's and stroke.

Removing clots and other blockages in the brain is so important to allow blood to flow without interruption, where blockages can be caused lack of oxygen and disrupting lines of communication between nerve cells, causing cell death.

In this latest study, researchers at Northwestern University Feinberg School of Medicine, using scanning technology to inspect small blood vessels, known as microvessle in rat brain. They found that cells on the walls of clogged arteries to improve blood flow to the seal and remove blockages.

Blood vessels in the older rats did not seem easy to move the blockage in the brain.

"The reduction in efficiency of protective mechanisms in the brain that are older and this effect of the function of nerve cells in the brain may significantly contribute to cognitive decline associated with age level," said Suzanna Petanceska researchers, from the division of neuroscience, the National Insititute of Aging, which funded this research.

"It may also be part of the mechanism by which vascular risk factors like high blood pressure and diabetes increase the risk of Alzheimer's disease at a certain age," said Petancesca.

This discovery comes online on May 26 in the journal Nature. [Mor]
