The dichotomized brain system is a concept that was generalized from the‘dual syndrome hypothesis’to explain the heterogeneity of cognitive impairment,in which anterior and posterior brain systems are independent but partially overlap.The dopaminergic system acts on the anterior brain and is responsible for executive function,working memory,and planning.In contrast,the cholinergic system acts on the posterior brain and is responsible for semantic fluency and visuospatial function.Evidence from dopaminergic/cholinergic imaging or functional neuroimaging has shed significant insight relating to the involvement of the cerebellum in the cognitive process of patients with Parkinson’s disease.Previous research has reported evidence that the cerebellum receives both dopaminergic and cholinergic projections.However,whether these two neurotransmitter systems are associated with cognitive function has yet to be fully elucidated.Furthermore,the precise role of the cerebellum in patients with Parkinson’s disease and cognitive impairment remains unclear.Therefore,in this review,we summarize the cerebellar dopaminergic and cholinergic projections and their relationships with cognition,as reported by previous studies,and investigated the role of the cerebellum in patients with Parkinson’s disease and cognitive impairment,as determined by functional neuroimaging.Our findings will help us to understand the role of the cerebellum in the mechanisms underlying cognitive impairment in Parkinson’s disease. 展开更多

Early-life stress is associated with a high prevalence of mental illnesses such as post-traumatic stress disorders,attention-deficit/hyperactivity disorder,schizophrenia,and anxiety or depressive behavior,which constitute major public health problems.In the early stages of brain development after birth,events such as synaptogenesis,neuron maturation,and glial differentiation occur in a highly orchestrated manner,and external stress can cause adverse long-term effects throughout life.Our body utilizes multifaceted mechanisms,including neuroendocrine and neurotransmitter signaling pathways,to appropriately process external stress.Newborn individuals first exposed to early-life stress deploy neurogenesis as a stress-defense mechanism;however,in adulthood,early-life stress induces apoptosis of mature neurons,activation of immune responses,and reduction of neurotrophic factors,leading to anxiety,depression,and cognitive and memory dysfunction.This process involves the hypothalamus-pituitary-adrenal axis and neurotransmitters secreted by the central nervous system,including norepinephrine,dopamine,and serotonin.The rodent early-life stress model is generally used to experimentally assess the effects of stress during neurodevelopment.This paper reviews the use of the early-life stress model and stress response mechanisms of the body and discusses the experimental results regarding how early-life stress mediates stress-related pathways at a high vulnerability of psychiatric disorder in adulthood. 展开更多

General anesthesia is widely applied in clinical practice.However,the precise mechanism of loss of consciousness induced by general anesthetics remains unknown.Here,we measured the dynamics of five neurotransmitters,includingγ-aminobutyric acid,glutamate,norepinephrine,acetylcholine,and dopamine,in the medial prefrontal cortex and primary visual cortex of C57BL/6 mice through in vivo fiber photometry and genetically encoded neurotransmitter sensors under anesthesia to reveal the mechanism of general anesthesia from a neurotransmitter perspective.Results revealed that the concentrations of γ-aminobutyric acid,glutamate,norepinephrine,and acetylcholine increased in the cortex during propofol-induced loss of consciousness.Dopamine levels did not change following the hypnotic dose of propofol but increased significantly following surgical doses of propofol anesthesia.Notably,the concentrations of the five neurotransmitters generally decreased during sevoflurane-induced loss of consciousness.Furthermore,the neurotransmitter dynamic networks were not synchronized in the non-anesthesia groups but were highly synchronized in the anesthetic groups.These findings suggest that neurotransmitter dynamic network synchronization may cause anesthetic-induced loss of consciousness. 展开更多

Alzheimer's disease is a common neurodegenerative disorder in older adults.Despite its prevalence,its pathogenesis remains unclea r.In addition to the most widely accepted causes,which in clude excessive amyloid-beta aggregation,tau hyperphosphorylation,and deficiency of the neurotransmitter acetylcholine,numerous studies have shown that the dopaminergic system is also closely associated with the occurrence and development of this condition.Dopamine is a crucial catecholaminergic neurotransmitter in the human body.Dopamine-associated treatments,such as drugs that target dopamine receptor D and dopamine analogs,can improve cognitive function and alleviate psychiatric symptoms as well as ameliorate other clinical manifestations.Howeve r,therapeutics targeting the dopaminergic system are associated with various adverse reactions,such as addiction and exacerbation of cognitive impairment.This review summarizes the role of the dopaminergic system in the pathology of Alzheimer's disease,focusing on currently available dopamine-based therapies for this disorder and the common side effects associated with dopamine-related drugs.The aim of this review is to provide insights into the potential connections between the dopaminergic system and Alzheimer's disease,thus helping to clarify the mechanisms underlying the condition and exploring more effective therapeutic options. 展开更多

BACKGROUND Cognitive dysfunction is the main manifestation of central neuropathy.Although cognitive impairments tend to be overlooked in patients with diabetes mellitus(DM),there is a growing body of evidence linking DM to cognitive dysfunction.Hyperglycemia is closely related to neurological abnormalities,while often disregarded in clinical practice.Changes in cerebral neurotransmitter levels are associated with a variety of neurological abnormalities and may be closely related to blood glucose control in patients with type 2 DM(T2DM).AIM To evaluate the concentrations of cerebral neurotransmitters in T2DM patients exhibiting different hemoglobin A1c(HbA1c)levels.METHODS A total of 130 T2DM patients were enrolled at the Department of Endocrinology of Shanghai East Hospital.The participants were divided into four groups according to their HbA1c levels using the interquartile method,namely Q1(<7.875%),Q2(7.875%-9.050%),Q3(9.050%-11.200%)and Q4(≥11.200%).Clinical data were collected and measured,including age,height,weight,neck/waist/hip circumferences,blood pressure,comorbidities,duration of DM,and biochemical indicators.Meanwhile,neurotransmitters in the left hippocampus and left brainstem area were detected by proton magnetic resonance spectroscopy.RESULTS The HbA1c level was significantly associated with urinary microalbumin(mALB),triglyceride,low-density lipoprotein cholesterol(LDL-C),homeostasis model assessment of insulin resistance(HOMA-IR),and beta cell function(HOMA-β),N-acetylaspartate/creatine(NAA/Cr),and NAA/choline(NAA/Cho).Spearman correlation analysis showed that mALB,LDL-C,HOMA-IR and NAA/Cr in the left brainstem area were positively correlated with the level of HbA1c(P<0.05),whereas HOMA-βwas negatively correlated with the HbA1c level(P<0.05).Ordered multiple logistic regression analysis showed that NAA/Cho[Odds ratio(OR):1.608,95%confidence interval(95%CI):1.004-2.578,P<0.05],LDL-C(OR:1.627,95%CI:1.119-2.370,P<0.05),and HOMA-IR(OR:1.107,95%CI:1.031-1.188,P<0.01)were independent predictors of poor glycemic control.CONCLUSION The cerebral neurotransmitter concentrations in the left brainstem area in patients with T2DM are closely related to glycemic control,which may be the basis for the changes in cognitive function in diabetic patients. 展开更多

T cells are essential for a healthy life,performing continuously:immune surveillance,recognition,protection,activation,suppression,assistance,eradication,secretion,adhesion,migration,homing,communications,and additional tasks.This paper describes five aspects of normal beneficial T cells in the healthy or diseased brain.First,normal beneficial T cells are essential for normal healthy brain functions:cognition,spatial learning,memory,adult neurogenesis,and neuroprotection.T cells decrease secondary neuronal degeneration,increase neuronal survival after central nervous system(CNS) injury,and limit CNS inflammation and damage upon injury and infection.Second,while pathogenic T cells contribute to CNS disorders,recent studies,mostly in animal models,show that specific subpopulations of normal beneficial T cells have protective and regenerative effects in seve ral neuroinflammatory and neurodegenerative diseases.These include M ultiple Sclerosis(MS),Alzheimer’s disease,Parkinson’s disease,Amyotrophic Lateral Sclerosis(ALS),stro ke,CNS trauma,chronic pain,and others.Both T cell-secreted molecules and direct cell-cell contacts deliver T cell neuroprotective,neuro regenerative and immunomodulato ry effects.Third,normal beneficial T cells are abnormal,impaired,and dysfunctional in aging and multiple neurological diseases.Different T cell impairments are evident in aging,brain tumors(mainly Glioblastoma),seve re viral infections(including COVID-19),chro nic stress,major depression,schizophrenia,Parkinson’s disease,Alzheimer’s disease,ALS,MS,stro ke,and other neuro-pathologies.The main detrimental mechanisms that impair T cell function are activation-induced cell death,exhaustion,senescence,and impaired T cell stemness.Fo urth,several physiological neurotransmitters and neuro peptides induce by themselves multiple direct,potent,beneficial,and therapeutically-relevant effects on normal human T cells,via their receptors in T cells.This scientific field is called "Nerve-Driven Immunity".The main neurotransmitters and neuropeptides that induce directly activating and beneficial effects on naive normal human T cells are:dopamine,glutamate,GnRH-Ⅱ,neuropeptide Y,calcitonin gene-related peptide,and somatostatin.Fifth, "Personalized Adoptive Neuro-Immunotherapy".This is a novel unique cellular immunotherapy,based on the "Nerve-Driven Immunity" findings,which was recently designed and patented for safe and repeated rejuvenation,activation,and improvement of impaired and dysfunctional T cells of any person in need,by ex vivo exposure of the person’s T cells to neurotransmitters and neuropeptides.Personalized adoptive neuro-immunotherapy includes an early ex vivo personalized diagnosis,and subsequent ex vivo in vivo personalized adoptive therapy,tailo red according to the diagnosis.The Personalized Adoptive Neuro-Immunotherapy has not yet been tested in humans,pending validation of safety and efficacy in clinical trials,especially in brain tumors,chronic infectious diseases,and aging,in which T cells are exhausted and/or senescent and dysfunctional. 展开更多

Alzheimer’s disease(AD)is a neurodegenerative condition that disrupts nerve cell function due to the misfolding and buildup of proteins,resulting in cognitive loss and aberrant behavior.Microglia cellsare one of the crucial immune cells in the central nervous system.Depending on their activation levels,microglia cells in the degenerative phase of AD can serve either neuroprotective or neurotoxic roles.Microglia cells express several neurotransmitter receptors that play distinct functions in the degenerative progression of AD.These receptors facilitate bidirectional communication between microglia and nerve cells.The neurotransmitter receptors on microglia cells can mediate or affect the neuroprotective or toxic effects of microglia cells,thereby affecting AD pathology.This paper focuses on the gamma-aminobutyric acid,glutaminergic,cannabinoid,cholinergic,and adrenergic receptors on microglia cells and their relationship with AD.Understanding how neurotransmitter receptors on microglia function in AD will be crucial for identifying potential treatment targets. 展开更多

[Objectives] This study was carried out to explore the combined effects of Fu Zi(Radix Aconiti Lateralis Praeparata, the secondary root of perennial herbaceous plant Acontium carmichaeli Dehx. of family Ranunculaceae) and Rou Gui(Cortex Cinnamomi, the bark of Cinnamamunz cassia Presl of family Lauraceae) on intestinal neurotransmitters and microflora in rats with slow transit constipation(STC). [Methods] Experimental rats were given loperamide hydrochloride by gavage to induce STC, and then treated with Fu Zi alone, Rou Gui alone, a combination of Fu Zi and Rou Gui(2:1 w/w), and prucalopride, respectively, for 14 days. Meanwhile, the general condition, the time to first black stool and the rate of intestinal propulsion of rats in each group were observed after STC was induced and after drug treatment, and the pathological changes in rat colon were observed via hematoxylin-eosin(HE) staining, and the levels of colonic 5-hydroxytryptamine(HT), vasoactive intestinal peptide(VIP) and substance P(SP) were detected by ELISA, and the changes in intestinal flora were detected by 16S rRNA Real-time PCR. [Results] Compared with healthy rats, the time to first black stool and the rate of intestinal propulsion, colonic 5-HT and SP levels significantly decreased(p<0.01), while their colonic VIP level significantly increased(p<0.01). Compared with STC rats, the time to first black stool, the rate of intestinal propulsion, colonic 5-HT and SP levels in Fu Zi-Rou Gui(2:1) treated rats and prucalopride treated rats significantly increased(p<0.01), while their colonic VIP level significantly decreased(p<0.01). There was no significant difference in alpha diversity between healthy rats and STC rats. However, analysis on beta diversity revealed that there were differences in microflora structure and composition between them. Compared with healthy rats, the relative abundance of Firmicutes and Proteobacteria in STC rats significantly increased, while that of Bacteroidetes decreased. Compared with STC rats, the relative abundance of Proteobacteria decreased and that of Bacteroidetes and Firmicutes increased in Fu Zi-Rou Gui(2:1) treated rats;the relative abundance of Bacteroidetes and Proteobacteria decreased while that of Firmicutes increased in Fu Zi treated rats;the relative abundance of Proteobacteria decreased while that of Bacteroidetes increased in Rou Gui treated rats;the relative abundance of Firmicutes and Proteobacteria decreased while that of Bacteroidetes increased in prucalopride treated rats. The intestinal flora in rats of all groups was dominated by Lactobacillus spp. and other genera of anaerobic bacteria. Compared with healthy rats, the relative abundance of Lactobacillus spp. and Clostridium spp. in STC rats decreased, while those of Blautia spp. and Ruminococcus spp. and Allobaculum spp. increased. Compared with STC rats, the relative abundance of Lactobacillus spp. in all rats treated with drugs increased. [Conclusions] The combination of Fu Zi and Rou Gui(2:1) can effectively improve intestinal motility in STC rats by regulating intestinal microbial community and the levels of colonic neurotransmitters. 展开更多

Na^(+)/K^(+)-ATPase is a transmembrane protein that has important roles in the maintenance of electrochemical gradients across cell membranes by transporting three Na^(+)out of and two K^(+)into cells.Additionally,Na^(+)/K^(+)-ATPase participates in Ca^(2+)-signaling transduction and neurotransmitter release by coordinating the ion concentration gradient across the cell membrane.Na^(+)/K^(+)-ATPase works synergistically with multiple ion channels in the cell membrane to form a dynamic network of ion homeostatic regulation and affects cellular communication by regulating chemical signals and the ion balance among different types of cells.Therefo re,it is not surprising that Na^(+)/K^(+)-ATPase dysfunction has emerged as a risk factor for a variety of neurological diseases.However,published studies have so far only elucidated the important roles of Na^(+)/K^(+)-ATPase dysfunction in disease development,and we are lacking detailed mechanisms to clarify how Na^(+)/K^(+)-ATPase affects cell function.Our recent studies revealed that membrane loss of Na^(+)/K^(+)-ATPase is a key mechanism in many neurological disorders,particularly stroke and Parkinson's disease.Stabilization of plasma membrane Na^(+)/K^(+)-ATPase with an antibody is a novel strategy to treat these diseases.For this reason,Na^(+)/K^(+)-ATPase acts not only as a simple ion pump but also as a sensor/regulator or cytoprotective protein,participating in signal transduction such as neuronal autophagy and apoptosis,and glial cell migration.Thus,the present review attempts to summarize the novel biological functions of Na^(+)/K^(+)-ATPase and Na^(+)/K^(+)-ATPase-related pathogenesis.The potential for novel strategies to treat Na^(+)/K^(+)-ATPase-related brain diseases will also be discussed. 展开更多

Background:The active components of Horcha-6 were identified using liquid chromatography with tandem mass spectrometry.Also,we investigated the potential mechanisms that explain why Horcha-6 may be effective in treating migraines through the use of network pharmacology and a rat migraine model.Methods:After identifying the active components of Horcha-6,the corresponding genes of the active components’target were obtained from the Universal Protein database,and a“compound-target-disease”network was constructed using Cytoscape 3.9.0 software.For the in vivo experiments,nitroglycerin was injected intraperitoneally into rats to create a migraine model.Pre-treatment with Horcha-6 was administered orally for 14 days,and rats were subjected to migraine-related behavior tests.RNA sequencing was performed to identify the gene expression regulated by Horcha-6 in the trigeminal nerve.Results:A total of 903 chemical components of Horcha-6 have been collected in the liquid chromatography with tandem mass spectrometry.We discovered 55 of the Horcha-6 bio-active components that were evaluated based on their Percent Human Oral Absorption(≥30%)and DL values(≥0.185)on the traditional Chinese medicine systems pharmacology database.The“compound-target-disease”network contained 163 intersection targets with the migraine state.Gene Ontology analysis indicated that these components significantly regulated the immune response,vascular function,oxidative stress,etc.When Kyoto Encyclopedia of Genes and Genomes enrichment analysis was performed,we observed that most of the target genes were significantly enriched in the inflammation and neuro-related signaling pathway,toll-like receptor signaling pathway,neuroactive ligand-receptor interaction,etc.These predictions were further demonstrated via in vivo animal model experiments.The RNA sequencing results showed that 41 genes were down-regulated(P<0.05)and 86 genes were up-regulated(P<0.05)in the Horcha-6 treated group compared with the untreated group.Those genes were mainly involved in neuromodulation,vascular function,and hormone metabolism.Conclusion:The 55 bio-active components in Horcha-6 regulate inflammation,hormone metabolism,and neurotransmitters and have potential as a therapy to treat migraines. 展开更多

Dysregulation of neurotransmitter metabolism in the central nervous system contributes to mood disorders such as depression, anxiety, and post–traumatic stress disorder. Monoamines and amino acids are important types of neurotransmitters. Our previous results have shown that disco-interacting protein 2 homolog A(Dip2a) knockout mice exhibit brain development disorders and abnormal amino acid metabolism in serum. This suggests that DIP2A is involved in the metabolism of amino acid–associated neurotransmitters. Therefore, we performed targeted neurotransmitter metabolomics analysis and found that Dip2a deficiency caused abnormal metabolism of tryptophan and thyroxine in the basolateral amygdala and medial prefrontal cortex. In addition, acute restraint stress induced a decrease in 5-hydroxytryptamine in the basolateral amygdala. Additionally, Dip2a was abundantly expressed in excitatory neurons of the basolateral amygdala, and deletion of Dip2a in these neurons resulted in hopelessness-like behavior in the tail suspension test. Altogether, these findings demonstrate that DIP2A in the basolateral amygdala may be involved in the regulation of stress susceptibility. This provides critical evidence implicating a role of DIP2A in affective disorders. 展开更多

Historically,psychiatric diagnoses have been made based on patient’s reported symptoms applying the criteria from diagnostic and statistical manual of mental disorders.The utilization of neuroimaging or biomarkers to make the diagnosis and manage psychiatric disorders remains a distant goal.There have been several studies that examine brain imaging in psychiatric disorders,but more work is needed to elucidate the complexities of the human brain.In this editorial,we examine two articles by Xu et al and Stoyanov et al,that show developments in the direction of using neuroimaging to examine the brains of people with schizo-phrenia and depression.Xu et al used magnetic resonance imaging to examine the brain structure of patients with schizophrenia,in addition to examining neurotransmitter levels as biomarkers.Stoyanov et al used functional magnetic resonance imaging to look at modulation of different neural circuits by diagnostic-specific scales in patients with schizophrenia and depression.These two studies provide crucial evidence in advancing our understanding of the brain in prevalent psychiatric disorders. 展开更多

Delirium,a complex neurocognitive syndrome,frequently emerges following surgery,presenting diverse manifestations and considerable obstacles,especially among the elderly.This editorial delves into the intricate phenomenon of postoperative delirium(POD),shedding light on a study that explores POD in elderly individuals undergoing abdominal malignancy surgery.The study examines pathophysiology and predictive determinants,offering valuable insights into this challenging clinical scenario.Employing the synthetic minority oversampling technique,a predictive model is developed,incorporating critical risk factors such as comorbidity index,anesthesia grade,and surgical duration.There is an urgent need for accurate risk factor identification to mitigate POD incidence.While specific to elderly patients with abdominal malignancies,the findings contribute significantly to understanding delirium pathophysiology and prediction.Further research is warranted to establish standardized predictive for enhanced generalizability. 展开更多

The gut-brain connection is a bidirectional communication system that links the gut microbiome to the central nervous system (CNS). The gut-brain axis communicates through a variety of mechanisms, including the release of hormones, neurotransmitters, and cytokines. These signaling molecules can travel from the gut to the brain and vice versa, influencing various physiological and cognitive functions. Emerging therapeutic strategies targeting the gut-brain connection include probiotics, prebiotics, and faecal microbiota transplantation (FMT). Probiotics are live microorganisms that are similar to the beneficial bacteria that are naturally found in the gut. Prebiotics are non-digestible fibers that feed the beneficial bacteria in the gut. FMT is a procedure in which faecal matter from a healthy donor is transplanted into the gut of a person with a diseased microbiome. Probiotics, prebiotics, and FMT have been shown to be effective in treating a variety of gastrointestinal disorders, and there is growing evidence that they may also be effective in treating neurological and psychiatric disorders. This review explores the emerging field of the gut-brain connection, focusing on the communication pathways between the gut microbiome and the central nervous system. We summarize the potential roles of gut dysbiosis in various neurological and psychiatric disorders. Additionally, we discuss potential therapeutic strategies, research limitations, and future directions in this exciting area of research. More research is needed to fully understand the mechanisms underlying the gut-brain connection and to develop safe and effective therapies that target this pathway. However, the findings to date are promising, and there is the potential to revolutionize the way we diagnose and treat a variety of neurological and psychiatric disorders. 展开更多

During CNS development, the role of GABA is switched from an excitatory transmitter to an inhibitory transmitter, which is caused by an inhibition of calcium influx into postsynaptic neuron derived from release of GABA. The switch is influenced by the neuronal chloride concentration. When the neuronal chloride concentration is at a high level, GABA acts as an excitatory neurotransmitter. When neuronal chloride concentration decreases to some degree, GABA acts as an inhibitory neurotransmitter. The neuronal chloride concentration is increased by Na^+-K^+-Cl^-Cl^- cotransporters 1 (NKCC 1), and decreased by K^+-Cl^- cotransporter 2 (KCC2). 展开更多
