WebReactive gliosis is also considered a transient process, whereas a gliopathy is permanent. However, whether chronic reactive gliosis can produce a gliopathy is not understood. WebReactive astrogliosis is a response of activated astrocytes seen in many neurological diseases. It is at least partially disease specific. In most situations, it can be viewed as a defensive reaction counteracting acute stress, restoring the CNS homeostasis and limiting the tissue damage.
WebApr 11, 2024 · Medicinal treatment against epilepsy is faced with intractable problems, especially epileptogenesis that cannot be blocked by clinical antiepileptic drugs (AEDs) during the latency of epilepsy. Abnormal circuits of neurons interact with the inflammatory microenvironment of glial cells in epileptic foci, resulting in recurrent seizures and … 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.
