WebGliosis: A process leading to scars in the central nervous system that involves the production of a dense fibrous network of neuroglia (supporting cells) in areas of damage. Gliosis is a prominent feature of many diseases of the central nervous system, including multiple sclerosis and stroke. 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 serum components, to enter the brain. … 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 Microglia, another type of glial cell, act as macrophage-like cells in the CNS when activated.

WebGliosis is a process of scarring in the central nervous system. Gliosis is the reactive response of the glial cells in the central nervous system following a trauma or injury to the …
WebGliosis, including the activation and often proliferation of glial cells, is a non-specific phenomenon observed in neuro-degenerative diseases and brain injury. There is increasing recognition that reactive astrocytes are vital and central responders to CNS injury and disease, but there is no widely accepted definition of reactive astrogliosis. WebJul 30, 2004 · Reactive gliosis specifically referred to the accumulation of enlarged glial cells, notably microglia and astrocytes, appearing immediately after CNS injury has occurred.
WebInfection leads to extended reactive gliosis and destruction of infected cells in regeneration-incompetent organisms, restricting the spread of infection. In regeneration-competent organisms, however, limited gliosis and rapid regeneration can lead to intra-CNS spread of infection. For clarity, macroglia are shown as astroglial-like rather than ...
