Proliferation (growth by reproduction) of the neuroglial tissue in the central nervous system.
the response of astrocytes and microglia to any damage or 'insult' to the nervous system.
The process of scar formation after a spinal cord injury. Gliosis clears dead tissue and walls off the damaged region to prevent aberrant nerve cell activity, but it also inhibits the survival of neighboring cells. The resultant scar poses both a physical and chemical barrier to nerve cell regeneration.
a proliferation of glial cells in the brain; a condition frequently seen in people with HIV-related dementia.
scar tissue in the form of excess astrocytes, also called astroglia.
Excessive multiplication of glial cells.
The excess growth of astrocytes in the brain or spinal cord, usually occurring after injury to one of these parts.
Gliosis is a proliferation of astrocytes in damaged areas of the central nervous system (CNS). Astrocytes are relatively large glial cells and are the connective tissue cells of the CNS. Astrocytes have various functions, including accumulating in areas where nerve cells (neurons) have been damaged.
