ChAT-positive neurons participate in subventricular zone neurogenesis after middle cerebral artery occlusion in mice.
In this study, we assessed whether these ChAT(+) neurons also participate in stroke-induced neurogenesis. We used a permanent middle cerebral artery occlusion (MCAO) model produced by transcranial electrocoagulation in mice, atropine (muscarinic cholinergic receptor [mAchR] antagonist), and donepezil (acetylcholinesterase inhibitor) to investigate the role of ChAT(+) neurons in stroke-induced neurogenesis. We found that mAchRs, phosphorylated protein kinase C (p-PKC), and p-38 levels in the SVZ were upregulated in mice on day 7 after MCAO. MCAO also significantly increased the number of BrdU/doublecortin-positive cells and...

Bone Marrow-Derived Endothelial Progenitor Cells Protect Against Scopolamine-Induced Alzheimer-Like Pathological Aberrations
Abstract Vascular endothelial dysfunction plays a key role in the pathogenesis of Alzheimer’s disease (AD). Patients with AD have displayed decreased circulating endothelial progenitor cells (EPCs) which repair and maintain the endothelial function. Transplantation of EPCs has emerged as a promising approach for the management of cerebrovascular diseases including ischemic stroke, however, its impact on AD has been poorly described. Thus, the current study aimed at investigating the effects of bone marrow-derived (BM) EPCs transplantation in repeated scopolamine-induced cognitive impairment, an experimental mode...
