Reactive gliosisとは
Gliosis is a nonspecific reactive change of glial cells in response to damage to the central nervous system (CNS).

WebGliosis is the reactive response of the glial cells in the central nervous system following a trauma or injury to the brain. Gliosis Symptoms. Gliosis symptoms depend on the molecular and cellular changes of glial cells. The changes occur as part of a non-specific body response to damage and trauma that may occur in your central nervous system.
