WebAstrocytes participating in gliosis are referred to as reactive astrocytes. Gemistocytic astrocytes are assumed to be intensely active cells because the astrocytomas evolve into glioblastomas. Gliosis is a nonspecific reactive change of glial cells in response to damage to the central nervous system (CNS).
