Adipose-derived mesenchymal stem cells reduce autophagy in stroke mice by extracellular vesicle transfer of miR-25
Kuang, Yaoyun; Zheng, Xuan; Zhang, Lin; Ai, Xiaoyu; Venkataramani, Vivek; Kılıç, Ertuğrul; Hermann, Dirk M.; Majid, Arshad; Baehr, Mathias; Doeppner, Thorsten R. (Taylor & Francis Ltd, 2020)Grafted mesenchymal stem cells (MSCs) yield neuroprotection in preclinical stroke models by secreting extracellular vesicles (EVs). The neuroprotective cargo of EVs, however, has not yet been identified. To investigate ... -
Cellular prion protein promotes post-ischemic neuronal survival, angioneurogenesis and enhances neural progenitor cell homing via proteasome inhibition
Doeppner, Thorsten Roland; Kaltwasser, Britta; Schlechter, Jana; Jaschke, J.; Kılıç, Ertuğrul; Baehr, Mathias; Hermann, Dirk Matthias; Weise, Jens (Nature Publishing Group, 2015)Although cellular prion protein (PrPc) has been suggested to have physiological roles in neurogenesis and angiogenesis, the pathophysiological relevance of both processes remain unknown. To elucidate the role of PrPc in ... -
Emerging roles of extracellular vesicle-associated non-coding RNAs in hypoxia: Insights from cancer, myocardial infarction and ischemic stroke
Hermann, Dirk M.; Xin, Wenqiang; Baehr, Mathias; Giebel, Bernd; Doeppner, Thorsten R. (Ivyspring International Publisher, 2022)Hypoxia is a central pathophysiological component in cancer, myocardial infarction and ischemic stroke, which represent the most common medical conditions resulting in long-term disability and death. Recent evidence suggests ... -
Extracellular vesicles from hypoxia-preconditioned microglia promote angiogenesis and repress apoptosis in stroke mice via the TGF-beta/Smad2/3 pathway
Zhang, Lin; Wei, Wei; Ai, Xiaoyu; Kılıç, Ertuğrul; Hermann, Dirk M.; Venkataramani, Vivek; Baehr, Mathias; Doeppner, Thorsten R. (Springer Nature, 2021)Systemic transplantation of oxygen-glucose deprivation (OGD)-preconditioned primary microglia enhances neurological recovery in rodent stroke models, albeit the underlying mechanisms have not been sufficiently addressed. ... -
The indirect NMDAR antagonist acamprosate induces postischemic neurologic recovery associated with sustained neuroprotection and neuroregeneration
Doeppner, Thorsten Roland; Pehlke, Jens; Kaltwasser, Britta; Schlechter, Jana; Kılıç, Ertuğrul; Baehr, Mathias; Hermann, Dirk Matthias (Nature Publishing Group, 2015)Cerebral ischemia stimulates N-methyl-D-aspartate receptors (NMDARs) resulting in increased calcium concentration and excitotoxicity. Yet, deactivation of NMDAR failed in clinical studies due to poor preclinical study ... -
The indirect NMDAR inhibitor flupirtine induces sustained post-ischemic recovery, neuroprotection and angioneurogenesis
Jaeger, Hanna; Pehlke, Jens; Kaltwasser, Britta; Kılıç, Ertuğrul; Baehr, Mathias; Hermann, Dirk; Doeppner, Thorsten (Impact Journals, 2015)N-methyl-D-aspartate receptor (NMDAR) activation induces excitotoxicity, contributing to post-stroke brain injury. Hitherto, NMDAR deactivation failed in clinical trials due to insufficient pre-clinical study designs and ... -
Inhibition of fatty acid synthesis aggravates brain injury, reduces blood-brain barrier integrity and impairs neurological recovery in a murine stroke model
Janssen, Lisa; Ai, Xiaoyu; Zheng, Xuan; Wei, Wei; Çağlayan, Ahmet Burak; Kılıç, Ertuğrul; Wang, Ya-chao; Hermann, Dirk M.; Venkataramani, Vivek; Baehr, Mathias; Doeppner, Thorsten R. (Frontiers Media SA, 2021)Inhibition of fatty acid synthesis (FAS) stimulates tumor cell death and reduces angiogenesis. When SH-SY5Y cells or primary neurons are exposed to hypoxia only, inhibition of FAS yields significantly enhanced cell injury. ... -
Lithium-induced neuroprotection in stroke involves increased miR-124 expression, reduced RE1-silencing transcription factor abundance and decreased protein deubiquitination by GSK3 beta inhibition-independent pathways
Doeppner, Thorsten Roland; Kaltwasser, Britta; Sanchez-Mendoza, Eduardo H.; Çağlayan, Ahmet Burak; Baehr, Mathias; Hermann, Dirk M. (Sage Publication Inc., 2017)Lithium promotes acute poststroke neuronal survival, which includes mechanisms that are not limited to GSK3 inhibition. However, whether lithium induces long-term neuroprotection and enhanced brain remodeling is unclear. ... -
Neural progenitor cell-derived extracellular vesicles enhance blood-brain barrier integrity by NF-kappa B (Nuclear Factor-kappa B)-dependent regulation of ABCB1 (ATP-Binding Cassette Transporter B1) in stroke mice
Zhang, Lin; Graf, Irina; Kuang, Yaoyun; Zheng, Xuan; Haupt, Matteo; Majid, Arshad; Kılıç, Ertuğrul; Hermann, Dirk M.; Psychogios, Marios-Nikos; Weber, Martin S.; Ochs, Jasmin; Baehr, Mathias; Doeppner, Thorsten R. (Lippincott Williams & Wilkins, 2021)Objective: Extracellular vesicles (EVs) derived from neural progenitor cells enhance poststroke neurological recovery, albeit the underlying mechanisms remain elusive. Since previous research described an enhanced poststroke ... -
Post-stroke transplantation of adult subventricular zone derived neural progenitor cells - A comprehensive analysis of cell delivery routes and their underlying mechanisms
Doeppner, Thorsten Roland; Kaltwasser, Britta; Teli, Mahesh; Sánchez-Mendoza, Eduardo; Kılıç, Ertuğrul; Baehr, Mathias; Hermann, Dirk Matthias (Academic Press, 2015)With neuroprotective approaches having failed until recently, current focus on experimental stroke research has switched towards manipulation of post-ischemic neuroregeneration. Transplantation of subventricular zone (SVZ) ...
