A new starring role for astrocytes
Astrocytes, previously thought of as helper cells for neurons, have recently been shown to send signals themselves. The signals are chemical not electrical and astrocytes send them to neurons, vascular cells and other ...

Taking the fate of stem cells in hand: Researchers generate immature nerve cells
German biologists have deliberately transformed stem cells from the spinal cord of mice into immature nerve cells. This was achieved by changing the cellular environment, known as the extracellular matrix, using the substance ...

Neuron-nourishing cells appear to retaliate in Alzheimer's
When brain cells start oozing too much of the amyloid protein that is the hallmark of Alzheimer's disease, the astrocytes that normally nourish and protect them deliver a suicide package instead, researchers report.

Astrocytes found to bridge gap between global brain activity and localized circuits
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. ...
