Astrocytes do not express AQP1 in normal conditions, but in a recent report (13) in a nonhuman primate (Macaca fascicularis), a subtype of astrocytes mainly located in the white matter and the glia limitans did express this protein in the processes and perivascular endfeet.

Bergman glia constitutes a large volume fraction in cerebellum (33%), more than three times that of hippocampus and cortex [29, 40, 41].

Astrocyte-synapse structural plasticity

We showed that fluorocitrate, which specifically blocks glial metabolic activity by inhibiting the activity of aconitase, a Krebs cycle enzyme found exclusively in glia [33-36] and served as positive control in this study, reduced the pain response in both models as previous reported [12, 37, 38].

Puerarin alleviates neuropathic pain by inhibiting neuroinfiammation in spinal cord

* Microglia: These glia constitute the brain's immune defense, operating behind the blood-brain barrier to identify, hunt down, and destroy organisms that invade the brain.

Glial cells come out of the shadows: researchers have discovered that keeping these important cells healthy is essential to proper brain function

Similar effects were obtained when the concentration of [K.sup.+] ions in the axon perfusate was drastically reduced, thereby inducing depolarization of the axon but not of the glia. These results suggested that the increased rate of synthesis, delivery, or both, of [[H.sup.3]]RNA to the axon perfusate was mediated by the release of one or more neurotransmitters from the depolarized axon that activated receptors in the glial plasma membrane.

Gene expression in the squid giant axon: neurotransmitter modulation of RNA transfer from periaxonal glia to the axon

Alcohol is thought to affect the migration of neuronal and glia cells in the foetus's developing brain.

Scientists find possible causes for autism; RESEARCH

Mark Saltzman and Melissa Mahoney of Cornell University in Ithaca, New York first enzymatically dissociated fetal rat brain cells, resulting in a mixture of differentiated cells resembling neurons and glia. In a separate step, they produced microparticles from lactide-co-glycolide, in which nerve growth factor (NGF) and agents to alter its release were encapsulated.

Brain cell transplant with controlled-release nerve growth factor developed

Tests revealed that the mice who could not chew had lost essential cells called glia in the hippocampus, the area of the brain critical for learning.

These helper cells, called olfactory ensheathing glia (EG), are found only in nerves that carry odor sensations to the brain.
