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 ...

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) ...

The connection between perturbations in BBB barrier function and damage to the astrocyte network and its functions arises from BBB damage, leading to the extravasation of albumin. In the physiological ...

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 ...

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 ...

Silent cells deep in your spinal cord may hold a surprising key to healing after devastating injuries and brain disease. A ...

The concept of a “leaky” brain is an enigma, the fortress of our brain, seemingly protected by the blood-brain barrier now disrupted. However, to understand whether a breach has altered our cognitive ...

Breakthroughs, discoveries, and DIY tips sent every weekday. Terms of Service and Privacy Policy. How does the brain store—and access—our memories? While our ...

A project led by Johns Hopkins University has successfully imaged astrocytes, the brain's most abundant cells, in their natural state. The star-shaped astrocytes are known to be responsible for ...
