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 ... -
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 ... -
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 ... -
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-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. ... -
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) ... -
Sustained neurological recovery induced by resveratrol is associated with angioneurogenesis rather than neuroprotection after focal cerebral ischemia
Hermann, Dirk Matthias; Zechariah, Anil; Kaltwasser, Britta; Bosche, Bert; Çağlayan, Ahmet Burak; Kılıç, Ertuğrul; Doeppner, Thorsten Roland (Academic Press, 2015)According to the French paradox, red wine consumption reduces the incidence of vascular diseases even in the presence of highly saturated fatty acid intake. This phenomenon is widely attributed to the phytoalexin resveratrol, ... -
Systemic proteasome inhibition induces sustained post-stroke neurological recovery and neuroprotection via mechanisms involving reversal of peripheral immunosuppression and preservation of blood-brain-barrier integrity
Doeppner, Thorsten Roland; Kaltwasser, Britta; Kuckelkorn, Ulrike; Henkelein, Petra; Bretschneider, Eva; Kılıç, Ertuğrul; Hermann, Dirk M. (Springer, 2016)In view of its profound effect on cell survival and function, the modulation of the ubiquitin-proteasome-system has recently been shown to promote neurological recovery and brain remodeling after focal cerebral ischemia. ...
