Glial cell types that cause gliomas

Glial cell types that cause gliomas

Astrocytes, oligodendrocytes, and ependymocytes.

Astrocytes fix neurons to their blood supply and serve a number of important support and structural roles, oligodendrocytes coat axons in the CNS creating a myelin sheath allowing electrical signals in the nervous system to travel faster, and ependymocytes line the ventricular system of the brain and spinal cord, helping create and secrete cerebrospinal fluid (CSF).

Are gliomas found in different brain regions depending on age? 

Yes, gliomas are mostly supratentorial in adults but infratentorial in children.

Which is the most frequent glioma? 

Glioblastoma (grade IV astrocytoma) is the most common and most malignant brain tumor in adults.

It typically occurs in patients in the fourth and fifth decades of life.
