Alt...Mitochondrial dysfunction has emerged as a critical factor in the etiology of various neurodevelopmental disorders, including autism spectrum disorders, attention-deficit/hyperactivity disorder, and Rett syndrome. Although these conditions differ in clinical presentation, they share fundamental pathological features that may stem from abnormal mitochondrial dynamics and impaired autophagic clearance, which contribute to redox imbalance and oxidative stress in neurons. This review aimed to elucidate the relationship between mitochondrial dynamics dysfunction and neurodevelopmental disorders. Mitochondria are highly dynamic organelles that undergo continuous fusion and fission to meet the substantial energy demands of neural cells. Dysregulation of these processes, as observed in certain neurodevelopmental disorders, causes accumulation of damaged mitochondria, exacerbating oxidative damage and impairing neuronal function. The phosphatase and tensin homolog-induced putative kinase 1/E3 ubiquitin-protein ligase pathway is crucial for mitophagy, the process of selectively removing malfunctioning mitochondria. Mutations in genes encoding mitochondrial fusion proteins have been identified in autism spectrum disorders, linking disruptions in the fusion-fission equilibrium to neurodevelopmental impairments. Additionally, animal models of Rett syndrome have shown pronounced defects in mitophagy, reinforcing the notion that mitochondrial quality control is indispensable for neuronal health. Clinical studies have highlighted the importance of mitochondrial disturbances in neurodevelopmental disorders. In autism spectrum disorders, elevated oxidative stress markers and mitochondrial DNA deletions indicate compromised mitochondrial function. Attention-deficit/hyperactivity disorder has also been associated with cognitive deficits linked to mitochondrial dysfunction and oxidative stress. Moreover, induced pluripotent stem cell models derived from patients with Rett syndrome have shown impaired mitochondrial dynamics and heightened vulnerability to oxidative injury, suggesting the role of defective mitochondrial homeostasis in these disorders. From a translational standpoint, multiple therapeutic approaches targeting mitochondrial pathways show promise. Interventions aimed at preserving normal fusion-fission cycles or enhancing mitophagy can reduce oxidative damage by limiting the accumulation of defective mitochondria. Pharmacological modulation of mitochondrial permeability and upregulation of peroxisome proliferator-activated receptor gamma coactivator 1-alpha, an essential regulator of mitochondrial biogenesis, may also ameliorate cellular energy deficits. Identifying early biomarkers of mitochondrial impairment is crucial for precision medicine, since it can help clinicians tailor interventions to individual patient profiles and improve prognoses. Furthermore, integrating mitochondria-focused strategies with established therapies, such as antioxidants or behavioral interventions, may enhance treatment efficacy and yield better clinical outcomes. Leveraging these pathways could open avenues for regenerative strategies, given the influence of mitochondria on neuronal repair and plasticity. In conclusion, this review indicates mitochondrial homeostasis as a unifying therapeutic axis within neurodevelopmental pathophysiology. Disruptions in mitochondrial dynamics and autophagic clearance converge on oxidative stress, and researchers should prioritize validating these interventions in clinical settings to advance precision medicine and enhance outcomes for individuals affected by neurodevelopmental disorders.展开更多

文摘BACKGROUND Non-suicidal self-injury(NSSI)is common among adolescents with depressive disorders and poses a major public health challenge.Rumination,a key cognitive feature of depression,includes different subtypes that may relate to NSSI through distinct psychological mechanisms.However,how these subtypes interact with specific NSSI behaviors remains unclear.AIM To examine associations between rumination subtypes and specific NSSI behaviors in adolescents.METHODS We conducted a cross-sectional study with 305 hospitalized adolescents diagnosed with depressive disorders.The subjects ranged from 12-18 years in age.Rumi-nation subtypes were assessed using the Ruminative Response Scale,and 12 NSSI behaviors were evaluated using a validated questionnaire.Network analysis was applied to explore symptom-level associations and identify central symptoms.RESULTS The network analysis revealed close connections between rumination subtypes and NSSI behaviors.Brooding was linked to behaviors such as hitting objects and burning.Scratching emerged as the most influential NSSI symptom.Symptomfocused rumination served as a key bridge connecting rumination and NSSI.CONCLUSION Symptom-focused rumination and scratching were identified as potential intervention targets.These findings highlight the psychological significance of specific cognitive-behavioral links in adolescent depression and suggest directions for tailored prevention and treatment.However,the cross-sectional,single-site design limits causal inference and generalizability.Future longitudinal and multi-center studies are needed to confirm causal pathways and verify the generalizability of the findings to broader adolescent populations.
文摘Musculoskeletal injuries are among the most common causes of disability worldwide,with early detection and appropriate intervention critical to minimizing long-term complications.Infrared thermography(IRT)has emerged as a noninvasive,real-time imaging modality that captures superficial temperature changes reflecting underlying physiological processes such as inflammation and vascular alterations.This review explores the fundamental principles of medical thermography,differentiates between passive and active approaches,and outlines key technological advancements including artificial intelligence integration.The clinical utility of IRT is discussed in various contexts–ranging from acute soft tissue injuries and overuse syndromes to chronic pain and rehabilitation monitoring.Comparative insights with conventional imaging techniques such as ultrasound and magnetic resonance imaging are also presented.While IRT offers functional imaging capabilities with advantages in portability,safety,and speed,its limitations–such as lack of deep-tissue penetration and protocol standardization–remain significant barriers to broader adoption.Future directions include the integration of IRT with other imaging modalities and digital health platforms to enhance musculoskeletal assessment and injury prevention strategies.

文摘Aerobic glycolysis,also known as the Warburg effect,and the accumulation of lactate that it causes,are increasingly recognized outside the field of oncology as triggers of chronic non-neoplastic disorders.This review integrates preclinical and clinical evidence to evaluate the ability of melatonin to reverseWarburg-effect-like metabolic reprogramming.Literature on neurodegeneration,age-related sarcopenia,type 2 diabetes,chronic kidney disease,heart failure and pulmonary arterial hypertension(PAH)has been reviewed and synthesised.In all of these conditions,hypoxia-inducible factor 1α(HIF-1α)and pyruvate dehydrogenase kinase 4(PDK4)inhibit the pyruvate dehydrogenase complex.This diverts pyruvate away fromthe tricarboxylic acid(TCA)cycle and promotes glycolysis.In cell and animal models,melatonin consistently inhibits PDK4,destabilizes HIF-1αunder normoxic conditions,activates SIRT1/3-dependentmitochondrial biogenesis andmitophagy,and eliminates reactive oxygen and nitrogen species.These actions reduce lactate production,restore oxidative phosphorylation and attenuate tissue damage.This appears to induce cognitive and synaptic improvements in Alzheimer’s and Parkinson’s disease models,increased muscle mass and function in ageing rodents,improved insulin sensitivity alongside suppression of hepatic gluconeogenesis in diabetic models,reduced fibrosis in nephropathy,and normalization of vascular remodeling in hypoxia-induced pulmonary arterial hypertension(PAH).Early-stage clinical trials corroborate a decrease in oxidative and inflammatorymarkers,improved sleep quality and modest cognitive benefits.However,they report conflicting effects on insulin sensitivity,which are largely related to the dose and timing of administration in relation to food intake.Overall,the current data suggest that melatonin is a pleiotropic metabolic modulator capable of counteracting the Warburg phenotype in multiple organs.However,human studies remain scarce,and well-designed randomised trials incorporating chronotherapy are needed before clinical adoption.
文摘Obesity is widely recognized as a global epidemic,primarily driven by an imbalance between energy expenditure and caloric intake associated with a sedentary lifestyle.Diets high in carbohydrates and saturated fats,particularly palmitic acid,are potent inducers of chronic low-grade inflammation,largely due to disruptions in glucose metabolism and the onset of insulin resistance(Qiu et al.,2022).While many organs are affected,the brain,specifically the hypothalamus,is among the first to exhibit inflammation in response to an unhealthy diet,suggesting that obesity may,in fact,be a brain-centered disease with neuroinflammation as a central factor(Thaler et al., 2012).
文摘Cell function has a tight relationship with cell architecture.Distribution of proteins to the correct compartment is one of the functions of the traffic pathway through the Golgi apparatus.The others are to ensure proper protein folding,the addition of post-translational modifications,and delive ring to intracellular and extracellular destinations.Astrocytes are fundamental homeostatic cells,controlling multiple aspects of the central nervous system physiology,such as ion balance,nutrients,blood flow,neurotransmitte rs,and responses to insults.Astrocytes are polarized cells,and,such as neurons,extensively use the secretory pathway for secreting factors and exposing functional receptors,channels,and transporte rs on the plasma membrane.In this review,we will underline the importance of studying the Golgi apparatus and the secretory pathway in astrocytes,based on the possible tight connection between the Golgi apparatus and astrocytes'homeostatic function.Given the topic of this review,we will provide examples mostly about the Golgi apparatus structure,function,localization,and its involvement in astrocytes'homeostatic response,with an insight into congenital glycosylation disorders,as an example of a potential future field in the study of astrocyte homeostatic failu re and Golgi apparatus alteration.

文摘Background:Antipsychotic-induced movement disorders(AIMDs)are prevalent side effects of antipsychotics,particularly during the acute phase of treatment.This study aimed to elucidate the genetic mechanisms underlying AIMDs using a genome-wide association study(GWAS).Methods:GWASs on AIMDs were conducted in three independent cohorts:a discovery cohort of 3067 patients(2016 subjects were reserved after quality control),a validation cohort of 277 patients,and a multi-ancestry validation cohort of 766 patients.Subsequent post-GWAS analyses included gene-based analyses,transcriptome-wide association studies(TWASs),and polygenic risk score(PRS)profiling.Results:Our study identified two loci located in RAB44 gene(rs116249243,P=5.98×10^(-9);rs117097482,P=1.17×10^(-8))associated with extrapyramidal symptoms(EPSs),1 locus(rs6826172,P=5.56×10^(-9))related to akathisia,and 76 loci linked to involuntary movements(11 genes were mapped).Risk loci located in CNTNAP2,LUZP2,TMEM167A,and RAB44 genes were successfully replicated in the validation cohort,whereas the locus located in RAB44 was also replicated in the multi-ancestry cohort.Gene-based analyses indicated that XRCC4 and PAIP2B reached significance at the genome-wide level in involuntary movements.Tissue expression analysis revealed that involuntary movement-related genes are predominantly expressed in the substantia nigra.Additionally,the TWAS suggested a causal relationship between XRCC4 and involuntary movement.The PRSs derived from the discovery cohort significantly predicted AIMDs in the validation cohort,with area under the receiver operating characteristic curve(AUC)values from 0.60 to 0.80.Conclusions:Our findings highlight the role of substantia nigra related gene polymorphisms in AIMDs.This study provides novel insights into the pathogenesis of AIMDs and supports the potential for personalized treatment approaches for schizophrenia.

文摘Investigating the mechanisms underlying central nervous system disorders is a major scientific issue in the 21st century.However,the inaccessibility and complexity of the human brain have always represented a challenge in understanding the pathophysiology of the central nervous system.Brain organoids are self-assembled threedimensional aggregates derived from pluripotent stem cells with cell types and structures similar to the embryonic human brain,giving them potential for investigating the atypical cellular,molecular,and genetic characteristics characteristic of central nervous system disorders.Brain organoids also provide a platform for drug screening and serve as a potential source for transplantation therapy for brain injuries.However,the broad application of brain organoids is hampered by several limitations,such as the lack of high-fidelity cell types,insufficient maturation,and considerable heterogeneity,undermining their reliability in specific applications.This review summarizes brain organoid evolution,discusses recent technological and methodological innovations,and reviews their applications in drug screening,transplantation therapy,and disease modeling,as well as clinical research progress.Additionally,we emphasize the limitations of current brain organoid research and explore the potential for advancing the technology to enhance its applicability.
文摘Neurodevelopmental processes represent a finely tuned interplay between genetic and environmental factors,shaping the dynamic landscape of the developing brain.A major component of the developing brain that enables this dynamic is the white matter(WM),known to be affected in neurodevelopmental disorders(NDDs)(Rokach et al.,2024).WM formation is mediated by myelination,a multifactorial process driven by neuro-glia interactions dependent on proper neuronal functionality(Simons and Trajkovic,2006).Another key aspect of neurodevelopmental abnormalities involves neuronal dynamics and function,with recent advances significantly enhancing our understanding of both neuronal and glial mitochondrial function(Devine and Kittler,2018;Rojas-Charry et al.,2021).Energy homeostasis in neurons,attributed largely to mitochondrial function,is critical for proper functionality and interactions with oligodendrocytes(OLs),the cells forming myelin in the brain’s WM.We herein discuss the interplay between these processes and speculate on potential dysfunction in NDDs.

文摘Traditional psychiatric diagnosis relies on subjective symptom assessment,lacking objective biomarkers that hinder early detection and personalized treatment.Plasma proteins and polygenic risk score(PRS),as potential predictive tools,hold promise for advancing early diagnosis of mental disorders.This study aims to evaluate the predictive potential of proteomic features and PRS in multiple mental illnesses(depression,schizophrenia,and post-traumatic stress disorder(PTSD)).Using participant data from the UK Biobank-Pharma Proteomics Project,we screen protein associations with mental disorders through least absolute shrinkage and selection operator(LASSO)analysis and construct a Cox regression risk prediction model by integrating the PRS.Additionally,we evaluate predictive performance using 6 machine learning methods and Kaplan-Meier survival curves.Our findings reveal distinct predictive patterns across dis-orders.For depression,integrating plasma proteins with PRS significantly improves prediction beyond the clinical model(C-index=0.6322).For schizophrenia,adding plasma proteins enhances predictive performance,whereas PRS provides no significant improvement.For PTSD,neither plasma proteins nor PRS add substantial predictive value beyond clinical variables.Risk stratification analysis demonstrat that all three mental disorders models can clearly distinguish high-risk from low-risk groups(depression:HR=2.34,P<0.001;schizophrenia:HR=5.47,P<0.001;PTSD:HR=3.02,P<0.001).Al-though it shows good performance in short-term prediction,its long-term prediction ability has decreased,and it needs to be further optimized in the future.This study underscores the differential utility of biomarkers across mental disorders and provides a rationale for disorder-specific predictive modeling in precision psychiatry.
