Brain cells help neighboring nerves regenerate
Researchers have uncovered a completely unexpected way that the brain repairs nerve damage, wherein cells known as astrocytes deliver a protective protein to nearby neurons. view more (2008-05-28)
New brain cells implicated in machinery of cannabinoid signaling
The brain cells called astrocytes, and not just neurons, are sensitive to the substances called cannabinoids-the active chemicals in marijuana. view more (2008-03-27)
Astrocytes and synaptic plasticity
By mopping up excess neurotrophic factor from neuronal synapses, astrocytes may finely tune synaptic transmission to affect processes such as learning and memory, say Bergami et al. view more (2008-10-13)

Neuronal survival and axonal regrowth obtained in vitro
While repair of the central nervous system has long been considered impossible, French researchers from Inserm, the CNRS and the UPMC have just developed a strategy that could promote neuronal regeneration after injury. The in vitro studies have just been published in the journal PLoS ONE. view more (2009-07-27)
Epilepsy and brain pathology linked together by the protein ADK
The brain of individuals who suffer from epilepsy is characterized by astrogliosis, a brain pathology evidenced by a complex series of changes in the morphology and function of brain cells known as astrocytes. view more (2008-01-03)
Blood flow in brain takes a twist, affecting views of Alzheimer's
New findings that long-overlooked brain cells play an important role in regulating blood flow in the brain call into question one of the basic assumptions underlying today's most sophisticated brain imaging techniques and could open a new frontier when it comes to understanding Alzheimer's disease. view more (2006-01-06)
Targeting astrocytes slows disease progression in ALS
In what the researchers say could be promising news in the quest to find a therapy to slow the progression of amyotrophic lateral sclerosis (ALS), or Lou Gehrig's disease, scientists at the University of California, San Diego (UCSD) School of Medicine have shown that targeting neuronal support cells called astrocytes sharply slows disease... view more...

The immune system and Alzheimer's disease
Utrecht researchers, funded by NWO, have determined the role played by brain cells from the immune system that are located close to dying memory cells. The research will help determine the causes of Alzheimer's disease. In patients with Alzheimer's disease, the brain cells die off. The death of these neurones takes place primarily in the vicinity... view more... (2001-11-27)
Statins show dramatic drug and cell dependent effects in the brain
Besides their tremendous value in treating high cholesterol and lowering the risk of heart disease, statins have also been reported to potentially lower the risks of other diseases, such as dementia. view more (2009-10-29)
Scientists find how neural activity spurs blood flow in the brain
New research from Harvard University neuroscientists has pinpointed exactly how neural activity boosts blood flow to the brain. The finding has important implications for our understanding of common brain imaging techniques such as fMRI, which uses blood flow in the brain as a proxy for neural activity. view more (2008-06-26)
Dogma Destroyed: "Neural Glue" Can Communicate!
For a long time glyacytes were merely regarded as a kind of glue which fills up the extra-cellular space in the brain and stabilises the nerve cells. However, researchers from the University of Bonn, together with their Swiss colleagues, have been able to prove convincingly for the first time that this "neural glue" is more communicative... view more...

New insights into how brain responds to viral infection
Scientists at Columbia University Mailman School of Public Health have discovered that astrocytes, supportive cells in the brain that are not derived from an immune cell lineage, respond to a molecule that mimics a viral infection using cellular machinery similar to that used by classical immune cells in the blood. view more (2009-04-01)
Johns Hopkins scientists map brain area that may aid hunt for human brain stem cells
A study led by a Johns Hopkins neurosurgeon has provided the first comprehensive map of a part of the adult human brain containing astrocytes, cells known to produce growth factors critical to the regeneration of damaged neural tissue and that potentially serve as brain stem cells. view more (2006-02-17)
Astrocytes help separate man from mouse
A type of brain cell that was long overlooked by researchers embodies one of very few ways in which the human brain differs fundamentally from that of a mouse or rat, according to researchers who published their findings as the cover story in the March 11 issue of the Journal of Neuroscience. view more (2009-03-24)
Roots of epilepsy may lie in oft-ignored brain cells
Star-shaped brain cells that are often overlooked by doctors and scientists as mere support cells appear to play a key role in the development of epilepsy. view more (2005-08-15)
Stem cell therapy for spinal injury
Researchers at Karolinska Institutet have shown how the transplantation of stem cells improves recovery from spinal injury. However, a painful condition can also develop, which can be prevented if the stem cells are supplemented with a certain gene that controls their maturing process. The results are important for planning of stem cell therapy... view more... (2005-02-13)
Brain protein central to both Parkinson's, drug addiction identified
Scientists have identified a protein that appears not only to be central to the process that causes Parkinson's disease but could also play a role in muting the high from methamphetamine and other addictive drugs. view more (2009-05-05)
Harvard researchers publish MRI images of genes in action in the living brain
Biologists have just confirmed what poets have known for centuries: eyes really are windows of the soul-or at least of the brain. view more (2008-03-31)
