Astrocytes, the predominant glial population in the human central nervous system, play crucial roles in neuroprotection, immunity, and homeostasis. However, when exposed to certain neuroinflammatory ...

A newly developed system to deliver tiny capsules containing anti-inflammatory proteins to specific parts of the brain may help fight Alzheimer’s and Parkinson’s diseases. AstroCapsules, described in ...

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

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 ...

The human brain contains about 86 billion neurons. These cells fire electrical signals that help the brain store memories and send information and commands throughout the brain and the nervous system.

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 ...

Object recognition software is used by law enforcement to help identify suspects, by self-driving cars to navigate roadways and by many consumers to unlock their cell phones or pay for their morning ...

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 potential effects of astrocyte dysfunction in neurodegenerative diseases are summarized in Figure 2. AD is characterized clinically by cognitive loss in two or more domains, including memory, ...

A new study has pinpointed cells in the brains of mice that have the unique ability to proliferate and may help to repair damaged tissue. Scientists now need to determine if similar cells exist in ...
