Following nerve injury,axonal disconnection in neurons usually results in persistent functional deficits,such as paralysis.However,axons in the adult mammalian central nervous system (CNS) have very limited regenerative ability.Understanding the molecular mechanism of controlling axon regeneration can provide idea for the design of effective therapeutic interventions for CNS injury,such as spinal cord injuries.Efficient axonal regeneration is achieved via gene expression in the neuronal soma,axonal transport of raw materials along the shaft,and membrane and cytoskeleton assembly at the nerve growth cone.Each process is delicately regulated by spatial-temporal controlled signaling pathways that target distinct effectors.Gene expression in the neuronal soma,especially of transcription factors,is often activated immediately following nerve injury.Injury signals at distal axons are interpreted and transmitted back to the soma,initiating a stream of gene expression events which positively regulate subsequent axonal regeneration.Over the past few decades,extensive studies have identified many regeneration-associated genes,including CREB,nuclear factor of activated T-cells,protein 53,Sprr1a,c-Jun,Smad1,activating transcription factor 3,signal transducer and activator of transcription 3,SRF,Sox11,and Kruppel-like factors.However,we know far less about how the coordinated expression of these regeneration-associated genes is regulated during axonal regeneration.Indeed,it is possible that they are regulated by a single common upstream regulator.If so,identification of this upstream regulator will provide us with an invaluable target for the development of more effective treatments for traumatic nerve injuries.Adult dorsal root ganglion (DRG) neurons represent a favorable medium in which to study the molecular mechanisms controlling intrinsic neuronal axon growth ability.Axotomy of the peripheral branch of a DRG neuron,known as a “conditioning lesion”,has been well-documented to greatly accelerate axonal growth both in v 展开更多

MiR-219 and miR-338(miR-219/miR-338)are oligodendrocyte-specific microRNAs.The overexpression of these miRs in oligodendrocyte precursor cells promotes their differentiation and maturation into oligodendrocytes,which may enhance axonal remyelination after nerve injuries in the central nervous system(CNS).As such,the delivery of miR-219/miR-338 to the CNS to promote oligodendrocyte precursor cell differentiation,maturation and myelination could be a promising approach for nerve repair.However,nerve injuries in the CNS also involve other cell types,such as microglia and astrocytes.Herein,we investigated the effects of miR-219/miR-338 treatment on microglia and astrocytes in vitro and in vivo.We found that miR-219/miR-338 diminished microglial expression of pro-inflammatory cytokines and suppressed astrocyte activation.In addition,we showed that miR-219/miR-338 enhanced oligodendrocyte precursor cell differentiation and maturation in a scratch assay paradigm that re-created a nerve injury condition in vitro.Collectively,our results suggest miR-219/miR-338 as a promising treatment for axonal remyelination in the CNS following nerve injuries.All experimental procedures were approved by the Institutional Animal Care and Use Committee(IACUC),Nanyang Technological University(approval No.A0309 and A0333)on April 27,2016 and October 8,2016. 展开更多

Most current studies quantify axon regeneration by immunostaining regeneration-associated proteins,representing indirect measurement of axon lengths from both sensory neurons in the dorsal root ganglia and motor neurons in the spinal cord.Our recently developed method of in vivo electroporation of plasmid DNA encoding for enhanced green fluorescent protein into adult sensory neurons in the dorsal root ganglia provides a way to directly and specifically measure regenerating sensory axon lengths in whole-mount nerves.A mouse model of sciatic nerve compression was established by squeezing the sciatic nerve with tweezers.Plasmid DNA carrying enhanced green fluorescent protein was transfected by ipsilateral dorsal root ganglion electroporation 2 or 3 days before injury.Fluorescence distribution of dorsal root or sciatic nerve was observed by confocal microscopy.At 12 and 18 hours,and 1,2,3,4,5,and 6 days of injury,lengths of regenerated axons after sciatic nerve compression were measured using green fluorescence images.Apoptosis-related protein caspase-3 expression in dorsal root ganglia was determined by western blot assay.We found that in vivo electroporation did not affect caspase-3 expression in dorsal root ganglia.Dorsal root ganglia and sciatic nerves were successfully removed and subjected to a rapid tissue clearing technique.Neuronal soma in dorsal root ganglia expressing enhanced green fluorescent protein or fluorescent dye-labeled microRNAs were imaged after tissue clearing.The results facilitate direct time course analysis of peripheral nerve axon regeneration.This study was approved by the Institutional Animal Care and Use Committee of Guilin Medical University,China(approval No.GLMC201503010)on March 7,2014. 展开更多

Hypertension is a risk factor for a large number of vision-threatening eye disorders.In this study,we investigated for the first time the retinal neural structure of the hypertensive BPH/2J mouse(Schlager mouse)and compared it to its control counterpart,the normotensive BPN/3J strain.The BPH/2J mouse is a selectively inbred mouse strain that develops chronic hypertension due to elevated sympathetic nervous system activity.When compared to the BPN/3J strain,the hypertensive BPH/2J mice showed a complete loss of outer layers of the neural retina at 21 weeks of age,which was indicative of a severe vision-threatening disease potentially caused by hypertension.To elucidate whether the retinal neural phenotype in the BPH/2J strain was attributed to increased BP,we investigated the neural retina of both BPN/3J and BPH/2J mice at 4 weeks of age.Our preliminary results showed for the first time that the BPH/2J strain develops severe retinal neural damage at a young age.Our findings suggest that the retinal phenotype in the BPH/2J mouse is possibly due to elevated blood pressure and may be contributed by an early onset spontaneous mutation which is yet to be identified or a congenital defect occurring in this strain.Further characterization of the BPH/2J mouse strain is likely to i)elucidate gene defects underlying retinal disease;ii)understand mechanisms leading to neural retinal disease and iii)permit testing of molecules for translational research to interfere with the progression of retinal disease.The animal experiments were performed with the approval of the Royal Perth Hospital Animal Ethics Committee(R535/17-18)on June 1,2017. 展开更多

Extracellular vesicles,including exosomes and microvesicles,play a fundamental role in the activity of the nervous system,participating in signal transmission between neurons and providing the interaction of central nervous system with all body systems.In many neurodegenerative diseases,neurons pack toxic substances into vesicles and release them into the extracellular space,which leads to the spread of misfolded neurotoxic proteins.The contents of neuron-derived extracellular vesicles may indicate pathological changes in the central nervous system,and the analysis of extracellular vesicle molecular content contributes to the development of non-invasive methods for the diagnosis of many central nervous system diseases.Extracellular vesicles of neuronal origin can be isolated from various biological fluids due to their ability to cross the blood-brain barrier.Today,the diagnostic potential of almost all toxic proteins involved in nervous system disease pathogenesis,specificallyα-synuclein,tau protein,superoxide dismutase 1,FUS,leucine-rich repeat kinase 2,as well as some synaptic proteins,has been well evidenced.Special attention is paid to extracellular RNAs mostly associated with extracellular vesicles,which are important in the onset and development of many neurodegenerative diseases.Depending on parental cell type,extracellular vesicles may have different therapeutic properties,including neuroprotective,regenerative,and anti-inflammatory.Due to nano size,biosafety,ability to cross the blood-brain barrier,possibility of targeted delivery and the lack of an immune response,extracellular vesicles are a promising vehicle for the delivery of therapeutic substances for the treatment of neurodegenerative diseases and drug delivery to the brain.This review describes modern approaches of diagnosis and treatment of central nervous system diseases using extracellular vesicles. 展开更多

Oxidative stress contributes to the pathogenesis of neurodegenerative diseases.With the aim to find reagents that reduce oxidative stress,a phage display library was screened for peptides mimicking a2,6-sialyllactose(6'-SL),which is known to beneficially influence neural functions.Using Sambucus nigra lectin,which specifically binds to 6'-SL,we screened a phage display library and found a peptide comprising identical sequences of 12 amino acids.Mimetic peptide,reverse peptide and scrambled peptide were tested for inhibition of 6'-SL binding to the lectin.Indeed,lectin binding to 6'-SL was inhibited by the most frequently identified mimetic peptide,but not by the reverse or scrambled peptides,showing that this peptide mimics 6'-SL.Functionally,mimetic peptide,but not the reverse or scrambled peptides,increased viability and expression of neural cell adhesion molecule L1 in SK-N-SH human neuroblastoma cells,and promoted survival and neurite outgrowth of cultured mouse cerebellar granule neurons challenged by H_20_2-induced oxidative stress.The combined results indicate that the 6'-SL mimetic peptide promotes neuronal survival and neuritogenesis,thus raising hopes for the treatment of neurodegenerative diseases.This study was approved by the Medical Ethics Committee of Shantou University Medical College,China(approval No.SUMC 2014-004)on February 20,2014. 展开更多

The central nervous system is known to have limited regenerative capacity.Not only does this halt the human body’s reparative processes after central nervous system lesions,but it also impedes the establishment of effective and safe therapeutic options for such patients.Despite the high prevalence of stroke and spinal cord injury in the general population,these conditions remain incurable and place a heavy burden on patients’families and on society more broadly.Neuroregeneration and neural engineering are diverse biomedical fields that attempt reparative treatments,utilizing stem cells-based strategies,biologically active molecules,nanotechnology,exosomes and highly tunable biodegradable systems(e.g.,certain hydrogels).Although there are studies demonstrating promising preclinical results,safe clinical translation has not yet been accomplished.A key gap in clinical translation is the absence of an ideal animal or ex vivo model that can perfectly simulate the human microenvironment,and also correspond to all the complex pathophysiological and neuroanatomical factors that affect functional outcomes in humans after central nervous system injury.Such an ideal model does not currently exist,but it seems that the nonhuman primate model is uniquely qualified for this role,given its close resemblance to humans.This review considers some regenerative therapies for central nervous system repair that hold promise for future clinical translation.In addition,it attempts to uncover some of the main reasons why clinical translation might fail without the implementation of nonhuman primate models in the research pipeline. 展开更多

In the peripheral nervous system,the vast majority of axons are accommodated within the fibre bundles that constitute the peripheral nerves.Axons within the nerves are in close contact with myelinating glia,the Schwann cells that are ideally placed to respond to,and possibly shape,axonal activity.The mechanisms of intercellular communication in the peripheral nerves may involve direct contact between the cells,as well as signalling via diffusible substances.Neurotransmitter glutamate has been proposed as a candidate extracellular molecule mediating the cross-talk between cells in the peripheral nerves.Two types of experimental findings support this idea:first,glutamate has been detected in the nerves and can be released upon electrical or chemical stimulation of the nerves;second,axons and Schwann cells in the peripheral nerves express glutamate receptors.Yet,the studies providing direct experimental evidence that intercellular glutamatergic signalling takes place in the peripheral nerves during physiological or pathological conditions are largely missing.Remarkably,in the central nervous system,axons and myelinating glia are involved in glutamatergic signalling.This signalling occurs via different mechanisms,the most intriguing of which is fast synaptic communication between axons and oligodendrocyte precursor cells.Glutamate receptors and/or synaptic axon-glia signalling are involved in regulation of proliferation,migration,and differentiation of oligodendrocyte precursor cells,survival of oligodendrocytes,and re-myelination of axons after damage.Does synaptic signalling exist between axons and Schwann cells in the peripheral nerves?What is the functional role of glutamate receptors in the peripheral nerves?Is activation of glutamate receptors in the nerves beneficial or harmful during diseases?In this review,we summarise the limited information regarding glutamate release and glutamate receptors in the peripheral nerves and speculate about possible mechanisms of glutamatergic signalling in the nerves.We highli 展开更多

Unlike the peripheral nervous system (PNS), the central nervous system (CNS) has a low intrinsic regenerative capacity and has mechanisms that actively suppress axon regrowth, for example, glial scarring and myelin inhibition (Fischer, 2012). Even in the PNS, which has the principle ability to regenerate injured axons, functional recovery remains limited, particularly in cases where the nerve target has become unreceptive to re-innervation over time due to an insufficient axonal growth rate (Diekmann and Fischer, 2015). Progress towards robust neuroregenerative therapies depends upon an understanding of the relevant signaling and cytoskeletal proteins that drive and control axon extension. Muscle LIM protein (MLP), also known as cysteine and glycine-rich protein 3, was recently discovered to be one such protein that is expressed in regenerating rat neurons and whose overexpression can promote the axon regeneration of adult central, and peripheral neurons of different species (Levin et al., 2019). 展开更多

MicroRNAs (miRNAs) are small, noncoding transcripts, and ~22 nucleotides long, which belong to a class of endogenous small regulatory RNA molecules that target mRNAs and trigger either translational suppression or mRNA degradation [1–3]. Several studies have shown that miRNAs play crucial roles in neurogenesis and development of nervous system [4,5] and have distinct expression patterns within the developing brain and central nervous system (CNS)[6]. Abnormal expression of miRNAs has also been reported in dysregulated neural tube (NT) development including NT defects (NTDs)[7,8]. To date, however, all NTD-related miRNA profiles were obtained from different microarray platforms, which always contain limited probes, and the data obtained are less precise in quantitative analysis. No quantitatively profiled global miRNA expression in mouse NTD fetuses has been characterized so far. To gain further insight of the possible roles of miRNAs in NTDs, we used deep sequencing to carry out a comprehensive survey of miRNA expression in all-trans retinoic acid (RA)-induced NTD mouse fetuses collected from three different embryonic time points (E8.5, E9.5, and E10.5). This study is the first, to our knowledge, to report the deep sequencing miRNA profile, which defined unique gene expression signatures of a range of miRNAs and their potential regulatory networks in response to RA stress and the development of NTDs in mouse model. 展开更多

The devastating losses following traumatic spinal cord injury (SCI) encompass the motor, sensory and autonomic nervous systems. Neurogenic bowel is a slow transit colonic dysfunction marked by constipation, rectal evacuation difficulties, decreased anorectal sensation, fecal incontinence or some combination thereof. Furthermore, neurogenic bowel is one of the most prevalent comorbidities of SCI and is recognized by afflicted individuals and caregivers as a lifelong physical and psychological challenge that profoundly affects quality of life. The restoration of post-injury control of movement has received considerable scientific scrutiny yet the daily necessity of voiding the bowel and bladder remains critically under-investigated. Subsequently, physicians and caregivers are rarely presented with consistent, evidence-based strategies to successfully address the consequences of dysregulated voiding reflexes. Neurogenic bowel is commonly believed to result from the interruption of the supraspinal control of the spinal autonomic circuits regulating the colon. In this mini-review, we discuss the clinical challenges presented by neurogenic bowel and emerging pre-clinical evidence that is revealing that SCI also initiates functional remodeling of the colonic wall concurrent with a decrease in local enteric neurons. Since the enteric input to the colonic smooth muscle is the final common pathway for functional contractions of the colon, changes to the neuromuscular interface must first be understood in order to maximize the efficacy of therapeutic interventions targeting colonic dysfunction following SCI. 展开更多

Adult T-cell leukemia(ATL)is a mature T-cell malignancy caused by human T-cell leukemia virus type I infection,and 10%-25%of patients show central nervous system(CNS)involvement.CNS involvement significantly reduces survival and there are no effective treatments for CNS involvement.Therefore,an appropriate animal model is required to evaluate the inhibitory effects of novel drugs on the progression of ATL with CNS involvement.Here,we established a mouse model of ATL with CNS involvement using NOD.Cg-Prkdc scid Il2rg tm1Wjl/SzJ mice inoculated with ATL cells intramuscularly in the postauricular region,and these mice showed paraparesis.Of the 10 mice inoculated with ATL cells intramuscularly(I.M.)at 5 weeks of age,8(80%)showed paraparesis,whereas none of the 10 mice inoculated with ATL cells subcutaneously(S.C.)showed paraparesis.In the I.M.group,PCR detected HTLV-1-specific genes in the thoracic and lumbar vertebrae;however,in the S.C.group,the vertebrae were negative for HTLV-1 genes.Histological analysis revealed a particularly high incidence of tumors,characterized by accumulation of the injected cells,in the thoracic vertebrae of mice in the I.M.group.Tumor cell infiltration was relatively high in the bone marrow.Spinal cord compression caused by invasion of the tumor mass outside the pia mater was observed in the thoracic vertebrae of the spinal cord.In conclusion,we have reported a mouse model of tumor growth with paraparesis that may be used to assess novel therapeutic agents for ATL with CNS involvement. 展开更多

Stem cell transplantation has brought new hope for the treatment of neurological diseases.The key to stem cell therapy lies in inducing the specific differentiation of stem cells into nerve cells.Because the differentiation of stem cells in vitro and in vivo is affected by multiple factors,the final differentiation outcome is strongly associated with the microenvironment in which the stem cells are located.Accordingly,the optimal microenvironment for inducing stem cell differentiation is a hot topic.EGb761 is extracted from the leaves of the Ginkgo biloba tree.It is used worldwide and is becoming one of the focuses of stem cell research.Studies have shown that EGb761 can antagonize oxygen free radicals,stabilize cell membranes,promote neurogenesis and synaptogenesis,increase the level of brain-derived neurotrophic factors,and replicate the environment required during the differentiation of stem cells into nerve cells.This offers the possibility of using EGb761 to induce the differentiation of stem cells,facilitating stem cell transplantation.To provide a comprehensive reference for the future application of EGb761 in stem cell therapy,we reviewed studies investigating the influence of EGb761 on stem cells.These started with the composition and neuropharmacology of EGb761,and eventually led to the finding that EGb761 and some of its important components play important roles in the differentiation of stem cells and the protection of a beneficial microenvironment for stem cell transplantation. 展开更多

Almost any type of cells can secrete vesicles, especially stem cells. Recent years, stem cells are becoming a research hotspot of cytotherapy for their capacity of self-renewing, expansion and proliferation in vitro and the microvesicles derived from the conditioned medium of stem cells have been widely used to regenerative medicine because they are safer, easily obtained, measurable and cause no obvious immune rejection. Stem cells derived microvesicles have been confirmed to be closely related to the progress and treatment of atherosclerosis, diabetes, inflammation and tumor. This review focuses on the new progress of stem cells derived microvesicles treating various nervous system diseases and its application in biological therapy and the behind molecule mechanisms. 展开更多

Acute ethanol intoxication has a diversity of clinical pictures that extend from mere euphoria to severe neurological impairment culminating in coma. Although the majority of cases have a reversible and benign course, the situation needs a careful medical monitoring. Authors describe pharmacological aspects of the acute ethanol intoxication, with organs and systems affected during the consumption of exaggerated quantities. Correlations between blood alcohol concentration and neurological symptomatology are given, and a brief discussion of the criteria for the acute intoxication is made. The fact that this occurrence has been of little attention is due not only to the reversibility of the majority of symptoms, but also because that medical research has been ever since focused more on chronic diseases related to alcohol abuse, withdrawal syndrome and recently with hangover as an independent situation. With no specific antidote actually at hand, treatment is symptom-oriented and the pharmacological armamentarium is richer when it comes to dealing with withdrawal, abstinence and other chronic complications of ethanol abuse. 展开更多

Syncope is defined as a transient loss of consciousness due to global cerebral hypoperfusion, accompanied by loss of muscle tone and failure to maintain an active position. Vasovagal syncope (VVS) is the most common presentation of syncope, and its diagnostic criteria include:(1) absence of any other evident etiology for syncope or presyncope,(2) positive response to head-up tilt test with evident vasovagal reaction (hypotension and/or bradycardia), and (3) no concomitant chronic or acute disease [1, 2]. The onset of VVS peaks initially in childhood and adolescence, and accounts for 60%–70% of all syncopal cases. Clinicians pay great attention to syncope among children and adolescents, due to its high prevalence and its impact on patients’ quality of life. Affected individuals often experience mental stress, economic burdens, and accidental bodily injuries related to syncope [2]. While the pathogenesis of VVS is not fully understood, autonomic nervous dysfunction has been identified as a contributing mechanism. The examination of autonomic nervous function can provide important information about patients with syncope. 展开更多

To the Editor:Meningiomas are the most common central nervous system neoplasms.[1] The World Health Organization (WHO) 2016 classification system classifies meningiomas into three grades:grade Ⅰ (benign),grade Ⅱ (atypical),and grade Ⅲ (anaplastic/malignant) meningioma.[1] Benign meningiomas are usually associated with favorable prognosis;however,higher grade (WHO grades Ⅱ and Ⅲ) menigiomas are more aggressive,resulting in less favorable outcome. 展开更多
