Abstract

Reactive gliosis is a characteristic response of astrocytes to inflammation and trauma of the central nervous system. To investigate whether soluble factors (cytokines) from inflammatory mononuclear cells that accumulate at lesion sites can provide the cellular signals to initiate gliosis and to identify such cytokines, we have tested and found that supernatants derived from subsets of activated human T lymphocytes (CD8+ or CD4+) are potent mitogens for cultured human adult astrocytes. This effect is blocked by a neutralizing antibody to gamma-interferon (IFN). Recombinant IFN alone can induce proliferation of human adult astrocytes in vitro and increase the extent of trauma-initiated gliosis in the adult mouse brain. The astrocyte proliferation-inducing activity of supernatants of glial cultures treated with IFN can be completely blocked with IFN-neutralizing antibody, suggesting that the proliferative effect does not require intermediary cytokines or cells. These results implicate IFN as an important mediator of the gliosis observed in pathologic conditions of the adult central nervous system associated with infiltrating lymphocytes.

Abstract

While reactive gliosis is readily observed close to the site of cerebral injury, astrocyte reactivity can also occur in distant areas either ipsilateral or contralateral to the lesion site. The present experiments were designed to address the origin of contralateral gliosis in adult rats following a cortical stab wound injury. One-month-old rats were subjected to either left cortical stab wound alone, callosotomy alone, callosotomy plus left cortical stab wound, or no surgery; 7 days later, animals were sacrificed. Formalin-fixed, paraffin-embedded sections were obtained and immunostained for GFAP. While untreated controls showed no cortical gliosis, callosotomy alone induced mild bilateral cortical gliosis. Whether or not rats were subjected to a callosotomy, the left cortical stab wound produced identical results: severe ipsilateral cortical gliosis and moderate contralateral gliosis. In all lesion models, both the intensity of GFAP staining and the number of reactive astrocytes were most marked in cortical areas abutting the subarachnoid spaces and decreased gradually into the deeper cortical layers. Our results suggest that the origin of contralateral gliosis in cortical stab injury is more likely due to the release of soluble substance(s) which diffuse to distant areas, rather than the migration of astrocytes through the corpus callosum from the lesion site, or being subsequent to degeneration of neurons which fibers traverse the corpus callosum.
