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 … See more Reactive astrogliosis is the most common form of gliosis and involves the proliferation of astrocytes, a type of glial cell responsible for maintaining extracellular ion and neurotransmitter concentrations, … See more In general after any CNS insult, gliosis begins after the blood brain barrier is disrupted, allowing non-CNS molecules, such as blood and See more Gliosis is the universal response of the CNS to tissue injury and occurs as a result of many acute conditions such as trauma, ischemia, and stroke. Additionally, gliosis is present in a wide variety of CNS pathologies, including Alzheimer's disease, Korsakoff's syndrome See more • Bergmann gliosis See more Microglia, another type of glial cell, act as macrophage-like cells in the CNS when activated. Unlike other glial cell types, microglia are extremely sensitive to even small changes in the … See more Oligodendrocytes are another type of glial cell which generate and maintain the formation of myelin around the axons of large neurons in the CNS, allowing for rapid transmission of neural signals. Unlike astrocytes and microglia, oligodendrocytes … See more The implications of gliosis in various neuropathologies and injury conditions has led to the investigation of various therapeutic routes which would regulate specific aspects of … See more WebFeb 15, 2024 · Histologic analysis of LITT effects in pathologic states, performed exclusively in rodent models of glioma and metastasis, has revealed that LITT ablates tumor cells/tissue resulting in similar features of central necrosis with tissue breakdown, granulation tissue formation and surrounding edema. the prissteens
