WebNov 15, 2024 · Reactive astrogliosis is a defensive brain reaction which is aimed at (a) isolation of the damaged area from the rest of the CNS tissue, (b) reconstruction of the blood-brain barrier, and (c) facilitation of the remodelling of brain circuits in areas surrounding the lesioned region. 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 barrier. Like other forms of gliosis, astrogliosis accompanies traumatic brain injury as well as many neuropathologi…
