Neurorestorative Responses to Delayed Human Mesenchymal Stromal Cells Treatment of Stroke in Type 2 Diabetic Rats Basic Sciences
Conclusions—In T2DM stroke rats, delayed hMSC treatment significantly improves neurological functional outcome and increases neurorestorative effects and M2 macrophage polarization. Increasing brain platelet-derived growth factor expression may contribute to hMSC-induced neurorestoration.

Cell-Based Therapies for Stroke: Promising Solution or Dead End? Mesenchymal Stem Cells and Comorbidities in Preclinical Stroke Research
Conclusion The high prevalence of comorbidities in patients with stroke indicates the need for therapies in preclinical studies that take into account these comorbidities in order to avoid failures in translation to the patient. Preclinical studies are beginning to evaluate the efficacy of MSC treatment in stroke associated with comorbidities, especially hypertension, for ischemic and hemorrhagic stroke. Regarding aging and diabetes, only ischemic stroke studies have been performed. For the moment, few studies have been performed and contradictory results are being reported. These contradictory results may be due to the u...

Stroke Dysbiosis Index (SDI) in Gut Microbiome Are Associated With Brain Injury and Prognosis of Stroke
Conclusions: We developed an index to measure gut microbiota dysbiosis in stroke patients; this index was significantly correlated with patients' outcome and was causally related to outcome in a mouse model of stroke. Our model facilitates the potential clinical application of gut microbiota data in stroke and adds quantitative evidence linking the gut microbiota to stroke. Introduction Ischemic stroke imposes a heavy burden on society, with 24.9 million cases worldwide (1). Although intravenous thrombolysis and endovascular treatment greatly improve some patients' prognosis, the prognosis for most pa...

World-Wide Efficacy of Bone Marrow Derived Mesenchymal Stromal Cells in Preclinical Ischemic Stroke Models: Systematic Review and Meta-Analysis
Conclusions: Our results show worldwide efficacy of BM-MSCs in improving functional outcomes in pre-clinical animal models of stroke and support testing these cells in clinical trials in various ranges of time windows using different delivery routes. The continued growing number of publications showing functional benefit of BM-MSCs are now adding limited value to an oversaturated literature spanning 18 years. Researchers should focus on identifying definitive mechanisms on how BM-MSCs lead to benefit in stroke models. Introduction Ischemic stroke is the 5th leading cause of death and the leading cause of long term di...

Obesity-induced type 2 diabetes impairs neurological recovery after stroke in correlation with decreased neurogenesis and persistent atrophy of parvalbumin-positive interneurons
Type 2 diabetes (T2D) hampers stroke recovery though largely undetermined mechanisms. Few preclinical studies have investigated the effect of genetic/toxin-induced diabetes on long-term stroke recovery. However, the effects of obesity-induced T2D are mostly unknown. We aimed to investigate whether obesity-induced T2D worsens long-term stroke recovery through the impairment of brain's self-repair mechanisms - stroke-induced neurogenesis and parvalbumin (PV)+ interneurons-mediated neuroplasticity. To mimic obesity-induced T2D in the middle-age, C57bl/6j mice were fed 12 months with high-fat diet and subjected to transient mi...

Exosomes derived from bone marrow mesenchymal stem cells harvested from type two diabetes rats promotes neurorestorative effects after stroke in type two diabetes rats.
CONCLUSIONS: T2DM-MSC-Exo treatment for stroke in T2DM rats promotes neurorestorative effects and improves functional outcome. Down regulation of miR-9 expression and increasing its target ABCA1 pathway may contribute partially to T2DM-MSC-Exo treatment induced white matter remodeling and anti-inflammatory responses.

Predictive Risk Factors of In-Hospital Mortality Following Acute Stroke in the United States: Data from the Nationwide Inpatient Database, 2006-2010 (P02.015)
CONCLUSIONS: The rate of in-hospital mortality is relatively high following acute stroke (8.42%). We identified multiple risk factors of in-hospital mortality in acute stroke patients. The strongest risk factor is the type stroke (hemorrhagic). The present finding suggests that patients at increased risk of mortality can be identified and additional treatment for prevention might be warranted.Disclosure: Dr. Naderi has nothing to disclose.

Linagliptin enhances neural stem cell proliferation after stroke in type 2 diabetic mice.
In conclusion, we found no correlation between acute neuroprotection (occurring in both T2D and normal mice) and increased NSC proliferation (occurring only in T2D mice). However, our results show that linagliptin evokes a differential response on NSC proliferation after stroke in normal and T2D mice suggesting that DPP-4 inhibition effect in the CNS might go beyond the well known increase of GLP-1.

Fifty years of stroke researches in India
Tapas Kumar Banerjee, Shyamal Kumar DasAnnals of Indian Academy of Neurology 2016 19(1):1-8Currently, the stroke incidence in India is much higher than Western industrialized countries. Large vessel intracranial atherosclerosis is the commonest cause of ischemic stroke in India. The common risk factors, that is, hypertension, diabetes, smoking, and dyslipidemia are quite prevalent and inadequately controlled; mainly because of poor public awareness and inadequate infrastructure. Only a small number of ischemic stroke cases are able to have the benefit of thrombolytic therapy. Benefits from stem cell therapy in established ...

Stroke and the Cell Therapy Saga: Towards a Safe, Swift and Efficient Utilization of cells.
Abstract The first clinical trials of cell therapy in stroke were first published in the 2000s and consisted of neural stems cells transplanted via the intracerebral pathway. Since mesenchymal stem cells showed similar capacities to differentiate into neural cells and allowed autologous cell transplantation, they were then preferentially studied, including diabetes and hypertension. More recently, bone marrow derived mononuclear cells were successfully transplanted in stroke with no need of culture processing, and simple collection by density gradient centrifugation rendering them immediately ready for use. They i...

Endothelial Progenitor Cells: Therapeutic Perspective for Ischemic Stroke.
Abstract Endothelial progenitor cells (EPCs), which can be cultured in vitro from mononuclear cells in peripheral blood or bone marrow, express both hematopoietic stem cell and endothelial cell markers on their surface. They are believed to participate in endothelial repair and postnatal angiogenesis due to their abilities of differentiating into endothelial cells and secreting protective cytokines and growth factors. Mounting evidence suggests that circulating EPCs are reduced and dysfunctional in various diseases including hypertension, diabetes, coronary heart disease, and ischemic stroke. Therefore, EPCs have ...

MiR‐126 Contributes to Human Umbilical Cord Blood Cell‐Induced Neurorestorative Effects After Stroke in Type‐2 Diabetic Mice
Abstract Diabetes mellitus (DM) is a high risk factor for stroke and leads to more severe vascular and white‐matter injury than stroke in non‐DM. We tested the neurorestorative effects of delayed human umbilical cord blood cell (HUCBC) treatment of stroke in type‐2 diabetes (T2DM). db/db‐T2DM and db/+‐non‐DM mice were subjected to distal middle cerebral artery occlusion (dMCAo) and were treated 3 days after dMCAo with: (a) non‐DM + Phosphate buffered saline (PBS); (b) T2DM + PBS; (c) T2DM + naïve‐HUCBC; (d) T2DM + miR‐126−/−HUCBC. Functional evaluation, vascular and white‐matter cha...

miR-145 Regulates Diabetes-Bone Marrow Stromal Cell-Induced Neurorestorative Effects in Diabetes Stroke Rats
In rats with type 1 diabetes (T1DM), the therapeutic effects and underlying mechanisms of action of stroke treatment were compared between bone-marrow stromal cells (BMSCs) derived from T1DM rats (DM-BMSCs) and BMSCs derived from normal rats (Nor-BMSCs). The novel role of microRNA-145 (miR-145) in mediating DM-BMSC treatment-induced benefits was also investigated. T1DM rats (n = 8 per group) underwent 2 hours of middle cerebral artery occlusion (MCAo) and were treated 24 hours later with the one of the following (5 x 106 cells administered i.v.): (a) phosphate-buffered saline (PBS); (b) Nor-BMSCs; (c) DM-BMSCs; (d) DM-BMSC...
