A Strategy for Magnetic and Electric Stimulation to Enhance Proliferation and Differentiation of NPCs Seeded over PLA Electrospun Membranes. Biomedicines 2022; 10:2736. [PMID: 36359255 PMCID: PMC9687775 DOI: 10.3390/biomedicines10112736] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/09/2022] [Revised: 10/07/2022] [Accepted: 10/25/2022] [Indexed: 09/30/2023] Open
Abstract
Neural progenitor cells (NPCs) have been shown to serve as an efficient therapeutic strategy in different cell therapy approaches, including spinal cord injury treatment. Despite the reported beneficial effects of NPC transplantation, the low survival and differentiation rates constrain important limitations. Herein, a new methodology has been developed to overcome both limitations by applying a combination of wireless electrical and magnetic stimulation to NPCs seeded on aligned poly(lactic acid) nanofibrous scaffolds for in vitro cell conditioning prior transplantation. Two stimulation patterns were tested and compared, continuous (long stimulus applied once a day) and intermittent (short stimulus applied three times a day). The results show that applied continuous stimulation promotes NPC proliferation and preferential differentiation into oligodendrocytic and neuronal lineages. A neural-like phenotypic induction was observed when compared to unstimulated NPCs. In contrast, intermittent stimulation patterns did not affect NPC proliferation and differentiation to oligodendrocytes or astrocytes morphology with a detrimental effect on neuronal differentiation. This study provides a new approach of using a combination of electric and magnetic stimulation to induce proliferation and further neuronal differentiation, which would improve therapy outcomes in disorders such as spinal cord injury.

Hong Y, Lyu J, Zhu L, Wang X, Peng M, Chen X, Deng Q, Gao J, Yuan Z, Wang D, Xu G, Xu M. High-frequency repetitive transcranial magnetic stimulation (rTMS) protects against ischemic stroke by inhibiting M1 microglia polarization through let-7b-5p/HMGA2/NF-κB signaling pathway. BMC Neurosci 2022; 23:49. [PMID: 35927640 PMCID: PMC9351069 DOI: 10.1186/s12868-022-00735-7] [Citation(s) in RCA: 9] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/05/2022] [Accepted: 07/28/2022] [Indexed: 11/22/2022] Open
Abstract
Background Microglia assume opposite phenotypes in response to ischemic brain injury, exerting neurotoxic and neuroprotective effects under different ischemic stages. Modulating M1/M2 polarization is a potential therapy for treating ischemic stroke. Repetitive transcranial magnetic stimulation (rTMS) held the capacity to regulate neuroinflammation and astrocytic polarization, but little is known about rTMS effects on microglia. Therefore, the present study aimed to examine the rTMS influence on microglia polarization and the underlying possible molecular mechanisms in ischemic stroke models. Methods Previously reported 10 Hz rTMS protocol that regulated astrocytic polarization was used to stimulate transient middle cerebral artery occlusion (MCAO) rats and oxygen and glucose deprivation/reoxygenation (OGD/R) injured BV2 cells. Specific expression levels of M1 marker iNOS and M2 marker CD206 were measured by western blotting and immunofluorescence. MicroRNA expression changes detected by high-throughput second-generation sequencing were validated by RT-PCR and fluorescence in situ hybridization (FISH) analysis. Dual-luciferase report assay and miRNA knock-down were applied to verify the possible mechanisms regulated by rTMS. Microglia culture medium (MCM) from different groups were collected to measure the TNF-α and IL-10 concentrations, and detect the influence on neuronal survival. Finally, TTC staining and modified Neurological Severity Score (mNSS) were used to determine the effects of MCM on ischemic stroke volume and neurological functions. Results The 10 Hz rTMS inhibited ischemia/reperfusion induced M1 microglia and significantly increased let-7b-5p level in microglia. HMGA2 was predicted and proved to be the target protein of let-7b-5p. HMGA2 and its downstream NF-κB signaling pathway were inhibited by rTMS. Microglia culture medium (MCM) collected from rTMS treated microglia contained lower TNF-α concentration but higher IL-10 concentration than no rTMS treated MCM, reducing ischemic volumes and neurological deficits of MCAO mice. However, knockdown of let-7b-5p by antagomir reversed rTMS effects on microglia phenotype and associated HMGA/NF-κB activation and neurological recovery. Conclusion High-frequency rTMS could alleviate ischemic stroke injury through inhibiting M1 microglia polarization via regulating let-7b-5p/HMGA2/NF-κB signaling pathway in MCAO models.

Neuromodulation-Based Stem Cell Therapy in Brain Repair: Recent Advances and Future Perspectives. Neurosci Bull 2021; 37:735-745. [PMID: 33871821 DOI: 10.1007/s12264-021-00667-y] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/30/2020] [Accepted: 11/28/2020] [Indexed: 02/07/2023] Open
Abstract
Stem cell transplantation holds a promising future for central nervous system repair. Current challenges, however, include spatially and temporally defined cell differentiation and maturation, plus the integration of transplanted neural cells into host circuits. Here we discuss the potential advantages of neuromodulation-based stem cell therapy, which can improve the viability and proliferation of stem cells, guide migration to the repair site, orchestrate the differentiation process, and promote the integration of neural circuitry for functional rehabilitation. All these advantages of neuromodulation make it one potentially valuable tool for further improving the efficiency of stem cell transplantation.

Pang Y, Shi M. Repetitive Transcranial Magnetic Stimulation Improves Mild Cognitive Impairment Associated with Alzheimer's Disease in Mice by Modulating the miR-567/NEUROD2/PSD95 Axis. Neuropsychiatr Dis Treat 2021; 17:2151-2161. [PMID: 34239303 PMCID: PMC8259939 DOI: 10.2147/ndt.s311183] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/15/2021] [Accepted: 04/17/2021] [Indexed: 12/18/2022] Open
Abstract
BACKGROUND Mild cognitive impairment (MCI) is a typical symptom of early Alzheimer's disease (AD) and is driven by the dysfunction of microRNAs (miRs). Repetitive transcranial magnetic stimulation (rTMS) is a non-invasive technique for handling neuropsychiatric disorders and has universally effects on the functions of miRs. In the current study, the improvement effects of rTMS on MCI associated with AD were explored by focusing on miR-567/NEUROD2/PSD95 axis. METHODS MCI was induced in mice using scopolamine and was treated with rTMS of two frequencies (1 Hz and 10 Hz). The changes in cognitive function, brain structure, neurotrophic factor levels, and activity of miR-567/NEUROD2/PSD95 axis were assessed. The interaction between rTMS and miR-567 was further verified by inducing the level of miR-567 in AD mice. RESULTS The administrations of rTMS improved the cognitive function of AD mice and attenuated brain tissue destruction, which were associated with the restored production of BDNF and NGF. Additionally, rTMS administrations suppressed the expression of miR-567 and up-regulated the expressions of NEUROD2 and PSD95, which contributed to the improved condition in central nerve system. With the induced level of miR-567, the effects of rTMS were counteracted: the learning and memorizing abilities of mice were impaired, the brain neuron viability was suppressed, and the production of neurotrophic factors was suppressed even under the administration of rTMS. The changes in brain function and tissues were associated with the inhibited expressions of NEUROD2 and PSD95. CONCLUSION The findings outlined in the current study demonstrated that rTMS treatment could protect brain against AD-induced MCI without significant side effects, and the function depended on the inhibition of miR-567.

Regenerative Rehabilitation for Stroke Recovery by Inducing Synergistic Effects of Cell Therapy and Neurorehabilitation on Motor Function: A Narrative Review of Pre-Clinical Studies. Int J Mol Sci 2020; 21:ijms21093135.

Abstract
Neurological diseases severely affect the quality of life of patients. Although existing treatments including rehabilitative therapy aim to facilitate the recovery of motor function, achieving complete recovery remains a challenge. In recent years, regenerative therapy has been considered as a potential candidate that could yield complete functional recovery. However, to achieve desirable results, integration of transplanted cells into neural networks and generation of appropriate microenvironments are essential. Furthermore, considering the nascent state of research in this area, we must understand certain aspects about regenerative therapy, including specific effects, nature of interaction when administered in combination with rehabilitative therapy (regenerative rehabilitation), and optimal conditions. Herein, we review the current status of research in the field of regenerative therapy, discuss the findings that could hold the key to resolving the challenges associated with regenerative rehabilitation, and outline the challenges to be addressed with future studies. The current state of research emphasizes the importance of determining the independent effect of regenerative and rehabilitative therapies before exploring their combined effects. Furthermore, the current review highlights the progression in the treatment perspective from a state of compensation of lost function to that of a possibility of complete functional recovery.
