that some glial cells, including astroglia, can be directly converted into neurons by specific proteins, a transformation that may aid in the functional repair of damaged brain tissue. However, in order for the repaired brain areas to function properly, it is important that astroglia be directed into appropriate neuronal subclasses. In this study, we show that non

in Boston found that amyloid plaques may also increase the activity of astrocytes, nervous system cells that play a supporting role in brain function. This astrocyte hyperactivity... and have been shown to cause relatively acute, localized neuro-toxicity. We show that astrocytes could provide a network mechanism that may stretch the impact of plaques to more

Star-shaped cells in our brains called astrocytes were once considered little more than structures to fill the gaps between all-important neurons. But more recent evidence has emerged to reveal that those astrocytes play more than a supporting role; they are involved in information processing and signal transmission and they help to regulate

Astrocytes are abundant throughout the brainmaking up about half of its total volume. The fact that amyloid beta peptides are able to induce calcium waves in astrocyte networks is a new and potentially important finding in the search for a treatment or cure for Alzheimer's disease....

and the Children's Hospital of Philadelphia, provides the strongest evidence yet that a cell called an astrocyte is the culprit.
The astrocyte is known to have a wide range of functions, including supplying nutrients to other brain cells, and even helping the brain cope with damaged nerve cells.
In some brain diseases, the astrocytes swell up and behave differently

looking at a study and going "HUH?" is this one out of France entitled "Ketogenic diet and astrocyte/neuron metabolic interactions." Okay, I know what a ketogenic diet is (one that is low enough in carbohydrates to induce ketosis) and neuron metabolic interactions sounds like something to do with the brain. I didn't have a clue what an astrocyte was until I

"There must be a secondary process toxifying the amyloid; otherwise the neuron would self-intoxicate before it made a big plaque. The neuron would die first.”
