Gliosis is a nonspecific reactive change of glial cells in response to damage to the central nervous system (CNS). In most cases, gliosis involves the proliferation or hypertrophy of several different types of glial cells, including astrocytes, microglia, and oligodendrocytes. In its most extreme form, the proliferation associated with gliosis leads to the formation of a glial scar. The process of gliosis involves a series of cellular and molecular events that occur over several … WebGliosis occurs when your body creates more or larger glial cells (cells that support nerve cells). These new glial cells can cause scars in your brain that impact how your body works. Though they are not brain tumors, necrosis and gliosis can cause symptoms similar to brain tumors.
