Increased expression of the Ang‐II (Angiotensin II) precursor AGT in aged astrocytes lead to increased Ang‐II signaling from aged astrocytes to endothelium, thus increasingblood–brain barrier (BBB) ...

Scientists have discovered a way to help the brain clean itself of harmful Alzheimer’s plaques by activating its own support cells. By increasing a protein called Sox9, researchers were able to boost ...

Every stroke begins with a sudden interruption of blood flow in the brain. But what happens afterward—why neurons continue to ...

Resting brain stem cells hardly differ from normal astrocytes, which support the nerve cells in the brain. How can almost identical cells perform such different functions? The key lies in the ...

Previous studies have found similarities in gene expression between resting brain stem cells and normal astrocytes even though they have very different functions. New research into epigenetic changes ...

Alzheimer's disease (AD) is a neurodegenerative disorder that leads to progressive memory loss and a decline in mental ...

Astrocytes are star shaped cells that make up around 35% of human brain cells. They were once thought of as cells that simply supported neurons in the central nervous system (CNS). But in recent years ...

Resting brain stem cells hardly differ from normal astrocytes, which support the nerve cells in the brain. How can almost identical cells perform such different functions? The key lies in the ...

Researchers discovered that astrocytes form organized, brain-wide networks that enable long-range communication between regions. These dynamic pathways depend on gap junctions and can reorganize with ...

Long dismissed as ‘brain glue,’ star-shaped cells called astrocytes are emerging as a breakthrough in treating Alzheimer’s ...
