Cerebrolysin is a peptide preparation mimicking the action of neurotrophic factors and has beneficial effects on neurodegenerative diseases and stroke. The present study investigated the effect of Cerebrolysin on neurogenesis in a rat model of embolic middle cerebral artery occlusion (MCAo). Treatment with Cerebrolysin at doses of 2.5 and 5 ml/kg significantly increased the number of bromodeoxyuridine-positive (BrdU+) subventricular zone (SVZ) neural progenitor cells and doublecortin (DCX) immunoreactivity (migrating neuroblasts) in the ipsilateral SVZ and striatal ischemic boundary 28 days after stroke when the treatment was initiated 24 hr after stroke. The treatment also reduced TUNEL+ cells by ~50% in the ischemic boundary. However, treatment with Cerebrolysin at a dose of 2.5 ml/kg initiated at 24 and 48 hr did not significantly reduce infarct volume but substantially improved neurological outcomes measured by an array of behavioral tests 21 and 28 days after stroke. Incubation of SVZ neural progenitor cells from ischemic rats with Cerebrolysin dose dependently augmented BrdU+ cells and increased the number of Tuj1+ cells (a marker of immature neurons). Blockage of the PI3K/Akt pathway abolished Cerebrolysin-increased BrdU+ cells. Moreover, Cerebrolysin treatment promoted neural progenitor cell migration. Collectively, these data indicate that Cerebrolysin treatment when initiated 24 and 48 hr after stroke enhances neurogenesis in the ischemic brain and improves functional outcome and that Cerebrolysin-augmented proliferation, differentiation, and migration of adult SVZ neural progenitor cells contribute to Cerebrolysin-induced neurogenesis, which may be related to improvement of neurological outcome. The PI3K/Akt pathway mediates Cerebrolysin-induced progenitor cell proliferation. © 2010 Wiley-Liss, Inc.

Alzheimer's disease (AD) is characterized by degeneration of neocortex, limbic system, and basal forebrain, accompanied by accumulation of amyloid-β and tangle formation. Cerebrolysin (CBL), a peptide mixture with neurotrophic-like effects, is reported to improve cognition and activities of daily living in patients with AD. Likewise, CBL reduces synaptic and behavioral deficits in transgenic (tg) mice overexpressing the human amyloid precursor protein (hAPP). The neuroprotective effects of CBL may involve multiple mechanisms, including signaling regulation, control of APP metabolism, and expression of neurotrophic factors. We investigate the effects of CBL in the hAPP tg model of AD on levels of neurotrophic factors, including pro-nerve growth factor (NGF), NGF, brain-derived neurotrophic factor (BDNF), neurotropin (NT)-3, NT4, and ciliary neurotrophic factor (CNTF). Immunoblot analysis demonstrated that levels of pro-NGF were increased in saline-treated hAPP tg mice. In contrast, CBL-treated hAPP tg mice showed levels of pro-NGF comparable to control and increased levels of mature NGF. Consistently with these results, immunohistochemical analysis demonstrated increased NGF immunoreactivity in the hippocampus of CBL-treated hAPP tg mice. Protein levels of other neurotrophic factors, including BDNF, NT3, NT4, and CNTF, were unchanged. mRNA levels of NGF and other neurotrophins were also unchanged. Analysis of neurotrophin receptors showed preservation of the levels of TrKA and p75NTR immunoreactivity per cell in the nucleus basalis. Cholinergic cells in the nucleus basalis were reduced in the saline-treated hAPP tg mice, and treatment with CBL reduced these cholinergic deficits. These results suggest that the neurotrophic effects of CBL might involve modulation of the pro-NGF/NGF balance and a concomitant protection of cholinergic neurons. © 2012 Wiley Periodicals, Inc.

Background: Alzheimer's Disease (AD) and Fronto temporal lobar dementia (FTLD) are common causes of dementia in the aging population for which limited therapeutical options are available. These disorders are associated with Tau accumulation. We have previously shown that CerebrolysinTM (CBL), a neuropeptide mixture with neurotrophic effects, ameliorates the behavioral deficits and neuropathological alterations in amyloid precursor protein (APP) transgenic (tg) mouse model of AD by reducing hyper-phosphorylated Tau. CBL has been tested in clinical trials for AD, however it's potential beneficial effects in FTLD are unknown. For this purpose we sought to investigate the effects of CBL in a tg model of tauopathy. Accordingly, double tg mice expressing mutant Tau under the mThy-1 promoter and GSK3β (to enhance Tau phosphorylation) were treated with CBL and evaluated neuropathologically.Results: Compared to single Tau tg mice the Tau/GSK3β double tg model displayed elevated levels of Tau phosphorylation and neurodegeneration in the hippocampus. CBL treatment reduced the levels of Tau phosphorylation in the dentate gyrus and the degeneration of pyramidal neurons in the temporal cortex and hippocampus of the Tau/GSK3β double tg mice. Interestingly, the Tau/GSK3β double tg mice also displayed elevated levels of Dynamin-related protein-1 (Drp-1), a protein that hydrolyzes GTP and is required for mitochondrial division. Ultrastructural analysis of the mitochondria in the Tau/GSK3β double tg mice demonstrated increased numbers and fragmentation of mitochondria in comparison to non-tg mice. CBL treatment normalized levels of Drp-1 and restored mitochondrial structure.Conclusions: These results suggest that the ability of CBL to ameliorate neurodegenerative pathology in the tauopathy model may involve reducing accumulation of hyper-phosphorylated Tau and reducing alterations in mitochondrial biogenesis associated with Tau. © 2014 Rockenstein et al.; licensee BioMed Central Ltd.

Stroke | Year: 2016

Background and Purpose - The aim of this trial was to investigate whether stroke patients who receive Cerebrolysin show improved motor function in the upper extremities at day 90 compared with patients who receive a placebo. Methods - This study was a prospective, randomized, double-blind, placebo-controlled, multicenter, parallel-group study. Patients were treated with Cerebrolysin (30 mL/d) or a placebo (saline) once daily for 21 days, beginning at 24 to 72 hours after stroke onset. The patients also participated in a standardized rehabilitation program for 21 days that was initiated within 72 hours after stroke onset. The primary end point was the Action Research Arm Test score on day 90. Results - The nonparametric effect size on the Action Research Arm Test score on day 90 indicated a large superiority of Cerebrolysin compared with the placebo (Mann-Whitney estimator, 0.71; 95% confidence interval, 0.63-0.79; P<0.0001). The multivariate effect size on global status, as assessed using 12 different outcome scales, indicated a small-to-medium superiority of Cerebrolysin (Mann-Whitney estimator, 0.62; 95% confidence interval, 0.58-0.65; P<0.0001). The rate of premature discontinuation was <5% (3.8%). Cerebrolysin was safe and well tolerated. Conclusions - Cerebrolysin had a beneficial effect on function and global outcome in early rehabilitation patients after stroke. Its safety was comparable with that of the placebo, suggesting a favorable benefit/risk ratio. Because this study was exploratory and had a relatively small sample size, the results should be confirmed in a large-scale, randomized clinical trial.

Functionalized Magnetic Iron Oxide Nanoparticles (FMIONPs) are being explored for the development of various biomedical applications, e.g., cancer chemotherapy and/or several other radiological or diagnostic purposes. However, the effects of these NPs per se on the central nervous system (CNS) injury or repair are not well known. This review deals with different aspects of FMIONPs in relation to brain function based on the current literature as well as our own investigation in animal models of CNS injuries. It appears that FMIONPs are innocuous when administered intravenously within the CNS under normal conditions. However, abnormal reactions to FMIONPs in the brain or spinal cord could be seen if they are combined with CNS injuries e.g., hyperthermia or traumatic insults to the brain or spinal cord. Thus, administration of FMIONPs in vivo following whole body hyperthermia (WBH) or a focal spinal cord injury (SCI) exacerbates cellular damage. Since FMIONPs could help in diagnostic purposes or enhance the biological effects of radiotherapy/chemotherapy it is likely that these NPs may have some adverse reaction as well under disease condition. Thus, under such situation, adjuvant therapy e.g., Cerebrolysin (Ever NeuroPharma, Austria), a suitable combination of several neurotrophic factors and active peptide fragments are the need of the hour to contain such cellular damages caused by the FMIONPs in vivo. Our observations show that co-administration of Cerebrolysin prevents the FMIONPs induced pathologies associated with CNS injuries. These observations support the idea that FMIONPs are safe for the CNS in disease conditions when co-administered with cerebrolysin. This indicates that cerebrolysin could be used as an adjunct therapy to prevent cellular damages in disease conditions where the use of FMIONPs is required for better efficacy e.g., cancer treatment.

Object. Cerebrolysin is a unique peptide preparation that mimics the action of neurotrophic factors. This study was designed to investigate the effects of acute treatment of experimental closed head injury (CHI) in rats with Cerebrolysin on neurological function. Methods. Adult male Wistar rats (n = 60) were subjected to impact acceleration-induced CHI. Closed head injured rats received intraperitoneal injection of saline (n = 30) or Cerebrolysin (2.5 ml/kg, n = 30) starting 1 hour postinjury and administered once daily until they were killed (2 or 14 days after CHI). To evaluate functional outcome, the modified neurological severity score (mNSS), foot fault, adhesive removal, and Morris water maze (MWM) tests were performed. Animals were killed on Day 14 (n = 20) after injury, and their brains were removed and processed for measurement of neuronal cells, axonal damage, apoptosis, and neuroblasts. The remaining rats (n = 40) were killed 2 days postinjury to evaluate cerebral microvascular patency by fluorescein isothiocyanate (FITC)-dextran perfusion (n = 16) and to measure the expression of vascular endothelial growth factor (VEGF) and matrix metalloproteinase-9 (MMP-9) by using real-time reverse transcriptase-polymerase chain reaction (RT-PCR, n = 8) and by immunohistochemical analysis (n = 16). Results. At 14 days post-CHI, the Cerebrolysin treatment group exhibited significant improvements in functional outcomes (the adhesive removal, mNSS, foot-fault, and MWM tests), and significantly more neurons and neuroblasts were present in the dentate gyrus (DG) (p < 0.05) compared with the saline-treated group (p < 0.05). At 2 days post-CHI, the Cerebrolysin group exhibited a significantly higher percentage of phosphorylated neurofilament H (pNF-H)-positive staining area in the striatum (p < 0.05), a significant increase in the percentage of FITC-dextran perfused vessels in the brain cortex (p < 0.05), a significant increase in the number of VEGF-positive cells (p < 0.05), and a significant reduction in the MMP-9 staining area (p < 0.05) compared with the saline-treated group. There was no significant difference in mRNA levels of MMP-9 and VEGF in the hippocampus and cortex 48 hours postinjury between Cerebrolysin- and saline-treated rats that sustained CHI. Conclusions. Acute Cerebrolysin treatment improves functional recovery in rats after CHI. Cerebrolysin is neuroprotective for CHI (increased neurons in the dentate gyrus and the CA3 regions of the hippocampus and increased neuroblasts in the dentate gyrus) and may preserve axonal integrity in the striatum (significantly increased percentage of pNF-H-positive tissue in the striatum). Reduction of MMP-9 and elevation of VEGF likely contribute to enhancement of vascular patency and integrity as well as neuronal survival induced by Cerebrolysin. These promising results suggest that Cerebrolysin may be a useful treatment in improving the recovery of patients with CHI. © AANS, 2013.

Stroke | Year: 2013

BACKGROUND AND PURPOSE - : Cerebrolysin, a mixture of neurotrophic peptides, enhances neurogenesis and improves neurological outcome in experimental neurodegenerative diseases and stroke. The Sonic hedgehog (Shh) signaling pathway stimulates neurogenesis after stroke. The present study tests whether the Shh pathway mediates cerebrolysin-induced neurogenesis and improves neurological outcome after stroke. METHODS - : Rats subjected to embolic stroke were treated with cerebrolysin with or without cyclopamine. RESULTS - : Using neural progenitor cells derived from the subventricular zone of the lateral ventricle of adult rats, we found that cerebrolysin significantly increased neural progenitor cells proliferation and their differentiation into neurons and myelinating oligodendrocytes, which were associated with upregulation of Shh and its receptors patched and smoothened. Blockage of the Shh signaling pathway with a pharmacological smoothened inhibitor, cyclopamine, abolished cerebrolysin-induced in vitro neurogenesis and oligodendrogenesis. In the ischemic rats, treatment with cerebrolysin starting 24 hours after stroke significantly increased neural progenitor cell proliferation in the subventricular zone and enhanced neurogenesis, oligodendrogenesis, and axonal remodeling in the peri-infarct area. Moreover, profound neurological function improvements were observed in rats treated with cerebrolysin from week 3 to week 5 after stroke onset compared with vehicle-treated rats. However, in vivo inhibition of the Shh pathway with cyclopamine completely reversed the effects of cerebrolysin on neurorestoration and functional recovery. CONCLUSIONS - : These results demonstrate that the Shh pathway mediates cerebrolysin-enhanced neurogenesis and white matter remodeling and improves functional recovery in rats after stroke. © 2013 American Heart Association, Inc.

The safety of Cerebrolysin has been shown through many years of clinical use, observations from postmarketing surveillance studies, and safety data from randomized, controlled clinical trials. The reported events showed that adverse reactions to Cerebrolysin were generally mild and transient. Most common adverse events included vertigo, agitation and feeling hot. In the controlled clinical trials analyzed for this report, the incidence of adverse events was similar in Cerebrolysin- and placebo-treated groups. Cerebrolysin seems to be safe when used in combination with recombinant tissue-type plasminogen activator or cholinesterase inhibitors such as donepezil or rivastigmine. To our knowledge, Cerebrolysin was not associated with major changes in vital signs or laboratory parameters. Copyright © 2012 Prous Science, S.A.U. or its licensors. All rights reserved.

Cerebrolysin (EVER Neuro Pharma GmbH, Austria) is a peptidergic drug indicated for clinical use in stroke, traumatic brain injury and dementia. The therapeutic effect of Cerebrolysin is thought to ensure from its neurotrophic activity, which shares some properties with naturally occurring neurotrophic factors. However, the exact mechanism of action of Cerebrolysin is yet to be fully deciphered. This study aimed to investigate the neuroprotective effect of Cerebrolysin in a widely used in vitro model of hypoxia-induced neuronal cytotoxicity, namely cobalt chloride (CoCl2)-treatment of PC12 cells. CoCl2-cytotoxicity was indicated by a reduced cell-diameter, cell shrinkage, increased pro-apoptotic Caspase-activities and a decreased metabolic activity. Cerebrolysin maintained the cell-diameter of CoCl2-treated naïve PC12 cells, decreased the activation of Caspase 3/7 in CoCl2-stressed naïve PC12 cells and restored the cells' metabolic activity in CoCl2-impaired naïve and differentiated PC12 cells. Cerebrolysin treatment also decreased the levels of superoxide observed after exposure to CoCl2. Investigating the mechanism of action, we could demonstrate that Cerebrolysin application to CoCl2-stressed PC12 cells increased the phosphorylation of GSK3β, resulting in the inhibition of GSK3β. This might become clinically relevant for Alzheimer's disease, since GSK3β activity has been linked to the production of amyloid beta. Taken together, Cerebrolysin was found to have neuroprotective effects in CoCl2-induced cytotoxicity in PC12 cells. © 2014 ISDN.
