Glial Scar

Glial scar formation (gliosis) is a reactive cellular process involving astrogliosis that occurs after injury to the Central Nervous System. As with scarring in other organs and tissues, the glial scar is the body's mechanism to protect and begin the healing process in the nervous system.

In the context of neurodegeneration, formation of the glial scar has been shown to have both beneficial and detrimental effects. Particularly, many neuro-developmental inhibitor molecules are secreted by the cells within the scar that prevent complete physical and functional recovery of the central nervous system after injury or disease. On the other hand, absence of the glial scar has been associated with impairments in the repair of the blood brain barrier.

Famous quotes containing the word scar:

    Nothing is uglier than the sinner, nothing so leprous or fetid; the scar of his crimes is still raw, and he stinks like the cave of Hell.
    Aurelius Clemens Prudentius (c. 348–405)
