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) ...
Researchers at the Center for Neuroscience Imaging Research within the Institute for Basic Science (IBS) have uncovered a two-step mechanism by which the brain regulates blood volume—a breakthrough ...
In a recent primer paper published in the journal Current Biology, researchers elucidated the structure and function of the blood-brain barrier (BBB). It highlights the BBB as a complex, dynamic ...
Peter Searson is leading a Johns Hopkins University team that is unravelling how Alzheimer's and other diseases disrupt the blood-brain barrier, the complex interface that allows or blocks the passage ...
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 ...
More than 55 million people worldwide live with dementia, and Alzheimer’s disease accounts for the majority of cases. For ...
The cells that line the blood vessels in our brains are highly selective. By deciding which molecules are allowed in and out of our most important organ, the barrier these cells form is critical for ...
Scientists have engineered a nanowire platform that mimics brain tissue to study astrocytes, the star-shaped cells critical for brain health, for the first time in their natural state. Astrocytes are ...
