Possible Pathomechanisms Responsible for Injury to the Central Nervous System in the Settings of Chronic Cerebrospinal Venous Insufficiency
2012
The discovery of stenoses in the azygous and internal jugular veins, the so-called chronic cerebrospinal venous insufficiency that accompanies multiple sclerosis, has enabled the reinterpretation of knowledge about this neurologic dis- ease. Pathologic venous outflow from the central nervous system appears to lead to two main problems. Firstly, it disas- sembles the blood-brain barrier and may allow the penetration of nervous parenchyma by glutamate and leukocytes. Sec- ondly, it may result in significant hypoperfusion of the brain and spinal cord. These two overlapping pathologies are likely to trigger plaques through caspase-1-driven pyroptosis of oligodendrocytes and to evoke neurodegene…
Pharmacologic Inhibition of ADAM10 Attenuates Brain Tissue Loss, Axonal Injury and Pro-inflammatory Gene Expression Following Traumatic Brain Injury …
2021
The α-secretase A disintegrin and metalloprotease 10 (ADAM10) regulates various physiological and pathophysiological processes. Despite its broad functional implications during development, plasticity, and disease, no pharmacological approaches to inhibit ADAM10 in acute brain injury have been reported. Here, we examined the effects of the ADAM10 inhibitor GI254023X on the neurological and histopathological outcome after experimental traumatic brain injury (TBI). C57BL/6N mice were subjected to the controlled cortical impact (CCI) model of TBI or sham procedure and received GI254023X or vehicle during the acute phase of injury (n = 40, 100 mg/kg, 25% DMSO, 0.1 M Na2CO3, intraperitoneal, 30 …
