WebBackground: Reactive gliosis and scar formation after brain injury can inhibit the recovery process. As many glial cells utilize gap junctions for intercellular signaling, this study investigated whether two commonly used gap junction blockers, octanol and carbenoxolone, could attenuate reactive gliosis following a minor traumatic brain injury. 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 …
