Dementia is a serious condition that affects millions of people around the world. It slowly damages memory, thinking ability, ...

A growing body of research suggests astrocytes, star-shaped brain cells once dismissed as support players, may lead the way ...

Astrocytes — named for their star-like shape — are a type of brain cell as abundant as neurons in the central nervous system, but little is known about their role in brain health and disease. Many ...

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) ...

Astrocytes in the lateral hypothalamus region of the brain, an area involved in the regulation of sleep and wakefulness, play a key role in neuron activity in mice and affect their behavior, Canadian ...

Researchers have shown in mice that brain cells known as astrocytes are required for a signaling chemical called norepinephrine to modify brain activity, changing the textbook understanding that ...

A Kobe University research team has pinpointed the mechanism underlying astrocyte-mediated restoration of brain tissue after an injury. This could lead to new treatments that encourage regeneration by ...

American and Chilean researchers have identified a previously unknown mechanism of appetite control in the brain. Astrocytes— ...

Your brain’s “stop eating” signal may come from an unexpected source. Researchers found that astrocytes—once thought to just support neurons—actually play a key role in controlling appetite. After a ...
