Rapid disruption of axon-glial integrity in response to mild cerebral hypoperfusion.
Myelinated axons have a distinct protein architecture essential for action potential propagation, neuronal communication, and maintaining cognitive function. Damage to myelinated axons, associated with cerebral hypoperfusion, contributes to age-related cognitive decline. We sought to determine early alterations in the protein architecture of myelinated axons and potential mechanisms after hypop...
متن کاملEffect of Centella asiatica on pathophysiology of mild chronic cerebral hypoperfusion in rats
Centella asiatica extract on cognition and hippocampal pathology of mild chronic cerebral hypoperfusion (CCH) that was induced by permanent right common carotid artery occlusion (RCO) in rats. Materials and Methods: Sixty-four male Sprague-Dawley rats were randomly divided into four groups of Sham-veh, Sham-C. asiatica, RCO-veh and RCO-C. asiatica, which were further divided into short-term and...
متن کاملMinocycline reduces microgliosis and improves subcortical white matter function in a model of cerebral vascular disease.
Chronic cerebral hypoperfusion is a key mechanism associated with white matter disruption in cerebral vascular disease and dementia. In a mouse model relevant to studying cerebral vascular disease, we have previously shown that cerebral hypoperfusion disrupts axon-glial integrity and the distribution of key paranodal and internodal proteins in subcortical myelinated axons. This disruption of my...
متن کاملWhite matter lesions and glial activation in a novel mouse model of chronic cerebral hypoperfusion.
BACKGROUND AND PURPOSE Cerebrovascular white matter (WM) lesions are closely associated with cognitive impairment and gait disorders in the elderly. We have successfully established a mouse model of chronic cerebral hypoperfusion that may provide new strategies for the molecular analysis of cerebrovascular WM lesions. METHODS Adult C57Bl/6 male mice were subjected to bilateral common carotid ...
متن کاملOrthostatic Cerebral Hypoperfusion Syndrome
OBJECTIVE Orthostatic dizziness without orthostatic hypotension is common but underlying pathophysiology is poorly understood. This study describes orthostatic cerebral hypoperfusion syndrome (OCHOs). OCHOs is defined by (1) abnormal orthostatic drop of cerebral blood flow velocity (CBFv) during the tilt test and (2) absence of orthostatic hypotension, arrhythmia, vascular abnormalities, or oth...
