  2. Gliosis - Wikipedia

    en.wikipedia.org/wiki/Gliosis

    Micrograph showing gliosis in the cerebellum. Reactive astrocytes on the left display severe proliferation and domain overlap. 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, modulating synapse function, and forming the blood–brain ...

  3. Gliogenesis - Wikipedia

    en.wikipedia.org/wiki/Gliogenesis

    Cell replacement strategies are now intensely studied as a possible therapeutic intervention of glial associated neurodegenerative disorders and glial tumors. Similar to any novel strategy, however, set-backs and liabilities accompany the promises this technique withholds.

  4. Glial scar - Wikipedia

    en.wikipedia.org/wiki/Glial_scar

    A glial scar formation is a reactive cellular process involving astrogliosis that occurs after injury to the central nervous system.As with scarring in other organs and tissues, the glial scar is the body's mechanism to protect and begin the healing process in the nervous system.

  5. Gemistocyte - Wikipedia

    en.wikipedia.org/wiki/Gemistocyte

    Gemistocytes are glial cells that are characterized by billowing, eosinophilic cytoplasm and a peripherally positioned, flattened nucleus. Gemistocytes most often appear during acute injury; and eventually, shrink in size. [1] They are usually present in anoxic-ischemic brains, which occurs when there is a complete lack of blood flow to the brain.

  6. Glia - Wikipedia

    en.wikipedia.org/wiki/Glia

    Glial cells known as astrocytes enlarge and proliferate to form a scar and produce inhibitory molecules that inhibit regrowth of a damaged or severed axon. In the peripheral nervous system (PNS), glial cells known as Schwann cells (or also as neuri-lemmocytes) promote repair. After axonal injury, Schwann cells regress to an earlier ...

  7. Brain healing - Wikipedia

    en.wikipedia.org/wiki/Brain_healing

    Brain healing is the process that occurs after the brain has been damaged. If an individual survives brain damage, the brain has a remarkable ability to adapt. When cells in the brain are damaged and die, for instance by stroke, there will be no repair or scar formation for those cells.

  8. Rosenthal fiber - Wikipedia

    en.wikipedia.org/wiki/Rosenthal_fiber

    Rosenthal fibers. H&E staining showing these elongated eosinophilic structures in a case of pilocytic astrocytoma.Magnification 400x. A Rosenthal fiber is a thick, elongated, worm-like or "corkscrew" eosinophilic (pink) bundle that is found on staining of brain tissue in the presence of long-standing gliosis, occasional tumors, and some metabolic disorders.

  9. Astrogliosis - Wikipedia

    en.wikipedia.org/wiki/Astrogliosis

    Reactive astrogliosis is a spectrum of changes in astrocytes that occur in response to all forms of CNS injury and disease. Changes due to reactive astrogliosis vary with the severity of the CNS insult along a graduated continuum of progressive alterations in molecular expression, progressive cellular hypertrophy, proliferation and scar formation.
