Reactive astrocytosis
WebNational Center for Biotechnology Information 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 ...

WebAug 25, 2024 · In Dach-SMOX mice, both reactive astrocytosis and activation of glutamate release from astrocyte processes seem to contribute, together with increased reactive oxygen species (ROS) production, to the vulnerability to kainate excitotoxicity and epileptogenic activity [9,10]. WebReactive astrocytosis is a hallmark of mesial temporal lobe epilepsy. Astrocytes in an epileptogenic focus within the human hippocampus, surgically resected from patients with temporal lobe epilepsy, exhibit dramatic changes in their anatomy and biology.
WebEncouraged by the promising “in vivo” observations, “ex vivo” experiments were carried out to quantify the impact of EAm and PEm administration on markers of demyelination and inflammation, as well as on reactive astrocytosis/gliosis, lymphocyte infiltration and microglia activation.

Congratuations to Simon Kaja, PhD, for his research grant proposal entitled Polycystin-2: A novel target against reactive astrocytosis accepted for funding by the Eversight Center for Vision and Eye Banking Research. The proposed work was awarded a total of $15,000.
WebReactive astrocytosis is defined and characterized by gross hypertrophy of the cell body and processes of astrocytes in injured and/or diseased areas of the brain 17.
