Human glia are far more complex than mouse glia, and they help form many, many more connections, called synapses, between neurons. (nbcnews.com)

The study, out today in the journal Cell Stem Cell , suggests that the evolution of a subset of glia called astrocytes - which are larger and more complex in humans than other species - may have been one of the key events that led to the higher cognitive functions that distinguish us from other species.

Astrocytes are part of a larger class of brain cells known as glia, which are basically the "everything else" in the brain besides neurons. (alleninstitute.org)
The connection between astrocytes and brain disease is an age-old problem that's now taking on increased importance because of this emerging genetic evidence," said Baljit Khakh , Ph.D., a neuroscientist at UCLA who is also an Allen Distinguished Investigator . (alleninstitute.org)
The study also found that some - but not all - of the disease-linked behaviors in mice can be reversed by boosting the activity of a certain protein in astrocytes in one part of the brain. (alleninstitute.org)
Astrocytes make up as much as 20 to 40% of the cells in the human brain but their function remains mysterious. (alleninstitute.org)
As much as we don't understand about how our brains work and where things go wrong in disease, we know even less about astrocytes and other glial cells. (alleninstitute.org)
Khakh and his colleagues had also seen that striatum astrocytes look very different from astrocytes in other parts of the brain, lending further credence to the idea that the cells are not just glue. (alleninstitute.org)
To test that theory, the UCLA team "poked" mouse striatum astrocytes with 14 different types of experiments, including a model of Huntington's disease, and looked at how gene activity changed in the cells. (alleninstitute.org)
