In Mouse Study, Researchers Discover New Mechanism for Clearing Blockages from Smallest Blood Vessels – 1
Narrator: This is NIH Health Matters. I’m Joe Balintfy. Uninterrupted blood flow is critical for brain function. Dr. Suzana Petanceska at the National Institute of Aging explains that even tiny blockages in the smallest blood vessels—called microvessels—are bad.
Petanceska: Obstructed blood flow, even in the tiniest microvessel, has negative consequences on the connections between nerve cells, which is how they communicate and this is how the brain operates, and on the general health of individual nerve cells.
Narrator: The brain has many ways to maintain blood flow, but Petanceska adds that a recent study in mice has shown a previously unknown way microvessels clear blockages.
