A pioneer in the study of neural cells revealed today (Oct. 23, 2018) how a single mutation affecting the most common protein in a supporting brain cell produces devastating, fibrous globs. These, in turn, disturb the location ...

Neurons often get most of the credit for keeping our brains sharp and functioning—as well as most of the blame when it comes to brain diseases. But star-shaped cells called astrocytes, another abundant cell in the human ...

When the brain gets injured, star-shaped brain cells called astrocytes come to the rescue. In the case of glioma—the most common type of primary brain tumor—this protective action comes at a price.

Microglia—the brain's immune cells—play a primary role in removing cellular debris from the brain. According to a recent study by a Nagoya University-led research team in Japan, another kind of brain cell, called astrocyte, ...

Past neuroscience studies found that when the central nervous system (CNS) is damaged, for instance following a stroke or spinal cord injuries, the lesions become surrounded by borders of newly proliferated astrocytes.
Global network activity in the brain modulates local neural circuitry via calcium signaling in non-neuronal cells called astrocytes (Fig. 1), according to research led by Hajime Hirase of the RIKEN Brain Science Institute. ...
