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...

Donepezil promotes neurogenesis via Src signaling pathway in a rat model of chronic cerebral hypoperfusion.
In this study, we investigated whether donepezil could promote SVZ neurogenesis in chronic cerebral hypoperfusion (CCH) injury via Src signaling pathway. In the bilateral carotid artery occlusion (2VO) rat model, we observed more nestin/5-bromo-2'-deoxyuridine (BrdU)-positive cells and doublecortin (DCX)/BrdU-positive cells in the SVZ than that in the sham group. Further, donepezil obviously improved neurologic function after 2VO, induced the greater number of SVZ proliferative NSCs and neuroblasts, and elevated levels of Src, p-FGFR1, p-EGFR, p-Akt and p-Raf in ipsilateral SVZ. Lastly, Src inhibitor KX-01 abolished the be...
