Controversial drug shown to act on brain protein to cut alcohol use

...byincreasing the level of a brain protein known as glial cellline-derived neurotrophic factor, or GDNF. In a separate study, theydemonstrated that GDNF by itself decreases alcohol consumption.The research is being published in the January 19 issue of The Journalof Neuroscience."By identifying the brain pro...

Rats infected as newborns grew up vulnerable to memory problems during an immune challenge

...ly alterationS may be to the basic architecture of glial cells called astrocytes within the hippocampus, which in turn help the central nervous system respond to injury or infection. Because astrocytes also help to determine the number and connectivity of nervous system synapses early in life, especially t...

Powerful new tool for studying brain development

...onstrated that specific brain cells, called radial glial cells, likely gave rise to ependymomas. "Our demonstration that identical-looking ependymomas that arise in different regions of the central nervous system are distinct diseases because they arise from different stem cells is an important insight,"...

New compound stops brain cell degeneration in Alzheimer's disease

The report demonstrates that targeting excessive glial activation can suppress brain inflammation and neuron dysfunction in the hippocampus and protect against cognitive decline in an animal model. Neuron dysfunction can lead to further glia activation and contribute to further exacerbation of the disea...

Stem cells found in adult skin can be transplanted and function in mouse models of disease

...found that SKPs can efficiently generate a type of glial cell, called Schwann cells, that can myelinate demyelinated axons (part of a neuron), and that have been shown to provide a good growth environment for injured central nervous system axons. These types of axons normally do not regenerate. "Schwann...
