Astrocytes
Astrocytes are the glial cell which are present in brain and spinal cord. astrocytes perform many function such as metabolism , regulation of the cell 's energy, transport of the blood to the neuron.
Astrocytes participate in glutamate clearance with the help of specific glutamate transporter.

A 35 year old female presents with a history of several episodes, each separated by several months, in which she experiences brief periods of physical weakness, clumsiness of the legs and hands, visual disturbances, and mood swings. Her weakness is most prominent in the lower extremities. CT scans show evidence of multiple lesions in the white matter of the brain and spinal cord. During her last episode, there were increasing neurological deficits due to an increasing number of disseminated lesions....
