Reactive astrocytosis
WebHence, we deduced that microglial activation, accompanied by reactive astrocytosis, is likely a defining feature of EAP-induced depression. Neuroinflammation refers to the cellular and biochemical responses to different stimuli that occur in the CNS. 6 Glial activation is an important component of the entire series of events, which can ... WebInterventions that cause early disruption of glial scar formation typically impede restoration of neurological function. Marked reactive astrogliosis also develops in cells more distant …

WebDr. Ben Barres categorizes two types of reactive astrocytes, A1 and A2, and describes how they affect the fate of neurons after brain injuries. Data from his laboratory shows that A2 cells are induced after ischemia (low oxygen), and seem to release factors that could help neuron survival. WebNov 30, 2010 · Dark neurons appear to be in a shrunken or contracted state, and it is possible that this may be the result of contraction of cytoskeletal proteins such as actin. It has recently been shown that dark neuron formation could be prevented (in cerebral cortex biopsies) by blocking glutamate receptors ( Kherani and Auer 2008 ).
