Astrocytes are one of the most populous cell types of the brain and central nervous system and maintain vital roles in CNS structure, neuronal metabolism, neurogenesis, maintenance of the blood-brain barrier and much more. They do not, however, produce myelin in the peripheral nervous system.

Satellite glial cells are found within ganglia and are thought to play the role of the astrocyte within the PNS including support of neuronal metabolism. However, they are not involved in the production of myelin.

Guillain-Barre syndrome is an acute inflammatory demyelinating disease of the peripheral nervous system (PNS). In the PNS, myelin is produced by Schwann cells.

Schwann cells
QuestionChoice
The microglia cells are the immune cells of the central nervous system. Although they promote myelination by encouraging the differentiation of oligodendrocytes and clearing old myelin debris, they do not produce myelin themselves.

QuestionChoice
Oligodendrocytes are the myelin-producing cells of the central nervous system (CNS). Therefore they are not involved in Guillain-Barre syndrome but do produce the myelin involved in multiple sclerosis.

A 45-year-old male presents with symmetrical ascending limb weakness which began in his legs and has progressed proximally. 2 weeks ago he suffered an episode of gastroenteritis. He is diagnosed with Guillain-Barre syndrome, an immune-mediated demyelinating disease.

What cells produce the myelin involved in this disease?
