A collaborative French–Swiss study reveals a previously unknown role for astrocytes in the brain's information processing. Published in the journal Cell, the research shows that these glial cells 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) ...

As a neuromodulator, norepinephrine is a powerful force in the brain. We all know it orchestrates rapid changes in behavior such as the fight-or-flight response. Fewer people know that astrocytes ...

Astrocytes are found throughout the brain. Each astrocyte is in contact with several neurons and more than 100'000 synapses. A new study shows that, at the microscopic level, dozens of synapses from ...
