Abstract Background: Anisodine hydrobromide (AT3), an anti-cholinergic agent, could be delivered to the brain across the blood-brain barrier and has been used clinically for the treatment of cerebral ischemia/reperfusion injury. Endothelial dysfunction can be caused by hypoxia/reoxygenation (H/R) via oxidative stress and metabolic alterations. The present study investigated whether AT3 regulates the production of nitric oxide (NO) and reactive oxygen species (ROS), and the HIF-1α pathway via regulation of muscarinic acetylcholine receptors (mAChRs) in brain microvascular endothelial cells after H/R exposure. Methods: Under H/R conditions, hCMEC/D3 cerebral microvascular endothelial cells were treated with AT3. Specific inhibitors of M2- and M4- mAChRs… More >
