Reversal of Neuropsychiatric Comorbidities in an Animal Model of Temporal Lobe Epilepsy Following Systemic Administration of Dental Pulp Stem Cells and Bone Marrow Mesenchymal Stem Cells.
Introduction: We aim to investigate whether timed systemic administration of dental pulp stem cells (DPSCs) or bone marrow mesenchymal stem cells (BM-MSCs) with status epilepticus (SE) induced blood-brain barrier (BBB) damage could facilitate the CNS homing of DPSCs/BM-MSCs and mitigate neurodegeneration, neuroinflammation and neuropsychiatric comorbidities in an animal model of Temporal Lobe epilepsy (TLE).
Background: Cognitive impairments, altered emotional responsiveness, depression, and anxiety are the common neuropsychiatric co-morbidities observed in TLE patients. Mesenchymal stem cells (MSCs) transplantation has gained immense attention in treating TLE, as ~30% of patients do not respond to anti-epileptic drugs. While MSCs are known to cross the BBB, better CNS homing and therapeutic effects could be achieved when the systemic administration of MSC is timed with BBB damage following SE.
Objectives: The objectives of the present study are to investigate the effects of systemic administration of DPSCs/BM-MSCs timed with BBB damage on CNS homing of DPSCs/BM-MSCs, neurodegeneration, neuroinflammation and neuropsychiatric comorbidities in an animal model of TLE.
Methodology: We first assessed the BBB leakage following kainic acid-induced SE and timed the intravenous administration of DPSCs/BM-MSCs to understand the CNS homing/engraftment potential of DPSCs/BM-MSCs and their potential to mitigate neurodegeneration, neuroinflammation and neuropsychiatric comorbidities.
Results: Our results revealed that systemic administration of DPSCs/BM-MSCs attenuated neurodegeneration, neuroinflammation, and ameliorated neuropsychiatric comorbidities. Three months following intravenous administration of DPSCs/BM-MSCs, we observed a negligible number of engrafted cells in the corpus callosum, sub-granular zone, and sub-ventricular zone.
Conclusion: Thus, it is evident that functional recovery is still achievable despite poor engraftment of MSCs into CNS following systemic administration.
期刊介绍：
Current Gene Therapy is a bi-monthly peer-reviewed journal aimed at academic and industrial scientists with an interest in major topics concerning basic research and clinical applications of gene and cell therapy of diseases. Cell therapy manuscripts can also include application in diseases when cells have been genetically modified. Current Gene Therapy publishes full-length/mini reviews and original research on the latest developments in gene transfer and gene expression analysis, vector development, cellular genetic engineering, animal models and human clinical applications of gene and cell therapy for the treatment of diseases.
Current Gene Therapy publishes reviews and original research containing experimental data on gene and cell therapy. The journal also includes manuscripts on technological advances, ethical and regulatory considerations of gene and cell therapy. Reviews should provide the reader with a comprehensive assessment of any area of experimental biology applied to molecular medicine that is not only of significance within a particular field of gene therapy and cell therapy but also of interest to investigators in other fields. Authors are encouraged to provide their own assessment and vision for future advances. Reviews are also welcome on late breaking discoveries on which substantial literature has not yet been amassed. Such reviews provide a forum for sharply focused topics of recent experimental investigations in gene therapy primarily to make these results accessible to both clinical and basic researchers. Manuscripts containing experimental data should be original data, not previously published.
