The discovery of a clear, synaptic-like microvesicle in the adult hippocampal astrocyte, by Andrea Volterra's group at the University of Lausanne, Switzerland, provided the framework for understanding ...

We will begin by highlighting a subset of the many cellular functions of astrocytes, focusing specifically on those functions that have the most relevance to neurodegeneration (Figure 1). Other ...

Astrocytes may express ionotropic glutamate and gamma-aminobutyric acid (GABA) receptors, which allow them to sense and to respond to neuronal activity. However, so far the properties of astrocytes ...

Although a link has been established between chronic inflammation and neurodegenerative diseases, there have been many open questions regarding how cellular senescence, a process whereby cells that ...

Decades before Alzheimer’s disease symptoms appear, neurons become hyperactive, and the reason could be that astrocytes fail to keep them in check. In a bioRxiv preprint uploaded on April 26, ...

Astrocytes are star-shaped glial cells with many functions which include providing nutrient support to neurons, helping repair damage to nervous system tissue, regulating connectivity of brain ...

NEW YORK, NY (June 1, 2020) - A new study published today in Neuron led by The New York Stem Cell Foundation (NYSCF) Research Institute's Valentina Fossati, PhD, creates astrocytes - an integral ...

Neuroscientists from the Medical University of South Carolina (MUSC) report in Science Advances that star-shaped brain cells known as astrocytes can "turn off" neurons involved in relapse to heroin.

“The measure of intelligence is the ability to change” - Albert Einstein As we live in a dynamically changing environment, it is important for our brain to not only learn new things but also to modify ...

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, ...
