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 ... -
Conditioned medium derived from neural progenitor cells induces long-term post-ischemic neuroprotection, sustained neurological recovery, neurogenesis, and angiogenesis
Doeppner, Thorsten R.; Traut, Viktorija; Heidenreich, Alexander; Kaltwasser, Britta; Bosche, Bert; Bahr, Mathias; Hermann, Dirk M. (Springer, 2017)Adult neural progenitor cells (NPCs) induce post-ischemic long-term neuroprotection and brain remodeling by releasing of survival- and plasticity-promoting mediators. To evaluate whether secreted factors may mimic ... -
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. ... -
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. ... -
Ischemic post-conditioning induces post-stroke neuroprotection via Hsp70-mediated proteasome inhibition and facilitates neural progenitor cell transplantation
Doeppner, Thorsten R.; Doehring, Maria; Kaltwasser, Britta; Majid, Arshad; Lin, Fengyan; Bahr, Mathias; Kılıç, Ertuğrul; Hermann, Dirk M. (Humana Press Inc, 2017)In view of the failure of pharmacological therapies, alternative strategies promoting post-stroke brain repair are needed. Post-conditioning is a potentially promising therapeutic strategy, which induces acute neuroprotection ... -
Lithium modulates miR-1906 levels of mesenchymal stem cell-derived extracellular vesicles contributing to poststroke neuroprotection by toll-like receptor 4 regulation
Haupt, Matteo; Zheng, Xuan; Kuang, Yaoyun; Lieschke, Simone; Janssen, Lisa; Bosche, Bert; Jin, Fengyan; Hein, Katharina; Kılıç, Ertuğrul; Venkataramani, Vivek; Hermann, Dirk M.; Bahr, Mathias; Doeppner, Thorsten R. (Wiley, 2021)Lithium is neuroprotective in preclinical stroke models. In addition to that, poststroke neuroregeneration is stimulated upon transplantation of mesenchymal stem cells (MSCs). Preconditioning of MSCs with lithium further ... -
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 ...
