Latest Excitotoxicity Stories
New research by scientists at UC San Francisco shows that one of the brain's fundamental self-protection mechanisms depends on coordinated, finely calibrated teamwork among neurons and non-neural cells knows as glial cells, which until fairly recently were thought to be mere support cells for neurons.
Johns Hopkins biophysicists have discovered that full activation of a protein ensemble essential for communication between nerve cells in the brain and spinal cord requires a lot of organized back-and-forth motion of some of the ensemble's segments.
Studies suggest that neurotrophic factors, which play a role in the development and survival of neurons, have significant therapeutic and restorative potential for neurologic diseases such as Huntington's disease.
Researchers from Virginia Commonwealth University Massey Cancer Center and the VCU Institute of Molecular Medicine have discovered a mechanism by which glioblastoma multiforme (GBM), the most common form of brain cancer, promotes the loss of function or death of neurons, a process known as neurodegeneration.
Bochum's neurobiologists have found that certain receptors for the neurotransmitter glutamate determine the architecture of nerve cells in the developing brain.
Neuroscientists have identified a natural protection mechanism in some of the brain's nerve cells during the onset of stroke.
A protective molecule has been identified in the brain which, if used artificially, may prevent brain damage from the likes of stroke, head injury and Alzheimer's.
A team of researchers, led by Scott Oakes, at the University of California, San Francisco, has identified a way to prevent symptom onset, weight loss, and paralysis and extend survival in a mouse model of amyotrophic lateral sclerosis (ALS; also known as Lou Gehrig's disease), providing a new avenue of research for the development of therapeutics for ALS and other motor neuron diseases.
For the first time, research led by Youming Lu, PhD, MD, Professor of Neurology and Neuroscience at LSU Health Sciences Center New Orleans School of Medicine, has identified a novel mechanism that may trigger brain damage during stroke and identified a therapeutic approach to block it.
Biomedical scientists from the University of Central Florida and Louisiana State University have identified a way to block a "cell death signal" that they believe triggers brain damage during strokes.

- Specifically— The legendary sweat-cloth; the handkerchief of St. Veronica, according to tradition miraculously impressed with the mask of Christ; also, the napkin about Christ's head (Johu xx. 7).
- In general, any miraculous portrait of Christ.
