Amateur boxing linked to brain cell injury

... during a bout." They also had elevated levels of glial fibrillary acidic protein, which indicates damage ...d higher levels of neurofilament light protein and glial fibrillary acidic protein. Three months later, the boxers still had higher levels of neurofilament l...

Need to pull an all-nighter?

...y does not come from neurons, but from neighboring glial cells, which appear to produce the greatest amounts of nitric oxide. Until recently, glial cells have been assumed to play only a supportive role in the brain. Rosenberg speculates that the m...

Living view in animals shows how cells decide to make proteins

...a-Blanco said. For example, neurons reside next to glial cells in the brain, yet they express different proteins in different amounts, and detecting such differences in cell cultures can be exceedingly difficult, he said. "This is a powerful tool to apply to mouse genetics to learn when and where in the...

Stem cell therapy shows promise for rescuing deteriorating vision

...uous delivery system" to shuttle an agent known as glial cell line-derived neurotrophic factor or GDNF, Lund explains. "It's not a sensible thing to inject the eyes many times over years. The idea was to use the cells as a continuous delivery system, but we found they work quite well on their own." Lund...

How genetic malfunction causes a form of retardation

...ation of immature precursor cells into neurons and glial cells. Unlike neurons, which conduct nerve impulses, glial cells are supporting cells that surround neurons and insulate them from one another. In experimen...

Bioluminescence at the service of a novel cerebral imaging technique

...ells of the brain nervous system (both neurons and glial cells) in order to monitor the activity of the whole brain. Preliminary data are already available. For the first time, it is possible to draw up anatomical and functional maps of the brain (in this case, of the Drosophila) based on long-term recor...

Genetic fingerprints identify brain tumors' origins

...es for the location of PAs, as well as for another glial cell tumor called an ependymoma. In addition, scientists also detected these distinct patterns of expression in normal glia and stem cells from these brain locations, suggesting that genetic fingerprints can be used to identify the potential origins ...

Researchers develop marker that identifies energy-producing centers in nerve cells

...y the mitochondria in neuronal cells from those in glial cells," says the study's principal investigator, K... investigators are developing a similar marker for glial cells in the brain. ...

Does amateur boxing cause brain damage?

... The study found high CSF levels of neuronal and glial markers suggestive of brain damage after a fight. A particular marker for neuronal damage, neurofilament light (NFL), was four times higher in boxers within 10 days of the fight as compared with healthy non-athletes. These increased levels returned...

Gene therapy delivery of nerve growth factors reverses erectile dysfunction in animal model

...cine, researchers inserted either the gene for the glial cell line derived neurotrophic factor (GDNF) or the GDNF family ligand (neurturin) into a genetically engineered herpes simplex virus (HSV). They then injected either of the recombinant viruses into the damaged cavernous nerve of rats. GDNF is an imp...
