Background

The bidirectional relationship between Alzheimer's disease (AD) and periodontitis highlights a critical interface between oral and brain health, increasingly recognized as a key axis in aging-related degenerative diseases. This review synthesizes epidemiological, pathological, and mechanistic evidence underpinning their interconnected pathogenesis.

Results and Conclusion

Epidemiologically, periodontitis is associated with an increased risk of AD, while AD patients exhibit a higher prevalence of periodontitis, driven by cognitive decline-impaired oral hygiene and synergistic inflammatory mechanisms. Pathologically, periodontal pathogens (e.g., Porphyromonas gingivalis) translocate to the brain via hematogenous, trigeminal, or oral-intestinal pathways, inducing neuroinflammation, β-amyloid (Aβ) aggregation, and tau hyperphosphorylation through virulence factors like gingipains and LPS. Conversely, AD-related neurodegeneration disrupts bone homeostasis to aggravate periodontitis via multiple mechanisms: (1) Aβ-mediated osteoclast activation through RAGE/NF-κB signaling and suppression of osteoblastogenesis; (2) autonomic nervous system dysregulation, where sympathetic hyperactivity promotes RANKL-dependent bone resorption; and (3) endocrine dysfunction, including HPA axis hyperactivation (chronic hypercortisolism), sex hormone deficiency, insulin resistance, and growth hormone/IGF-1 insufficiency, all of which perturb the balance between bone formation and resorption. Aging exacerbates this bidirectional interplay through immunosenescence (e.g., impaired neutrophil phagocytosis, senescent microglia) and inflammaging, creating a pro-degenerative milieu that amplifies both diseases. Clinical interventions, such as periodontal therapy and microbiota modulation, show promise in reducing systemic inflammation and slowing AD progression, though causal links require validation. Future research must prioritize longitudinal cohort studies, pathogen-specific mechanistic investigations, and translational strategies targeting the oral-brain axis to develop preventive interventions for aging populations.

背景：阿尔茨海默病（AD）和牙周炎之间的双向关系突出了口腔和大脑健康之间的关键接口，越来越被认为是与衰老相关的退行性疾病的关键轴。这篇综述综合了流行病学，病理学和机械证据，支持其相互关联的发病机制。结果和结论：流行病学上，牙周炎与AD风险增加有关，而AD患者表现出更高的牙周炎患病率，这是由认知能力下降、口腔卫生受损和协同炎症机制驱动的。病理上，牙周病原体（如牙龈卟啉单胞菌）通过血液、三叉神经或口腔-肠道途径转运到大脑，通过毒力因子如牙龈痛和LPS诱导神经炎症、β-淀粉样蛋白（Aβ）聚集和tau蛋白过度磷酸化。相反，ad相关神经退行性变通过多种机制破坏骨稳态，加重牙周炎：(1)a β通过RAGE/NF-κB信号介导破骨细胞活化，抑制成骨细胞形成；(2)自主神经系统失调，交感神经过度活跃促进rankl依赖性骨吸收；(3)内分泌功能障碍，包括HPA轴过度激活（慢性高皮质醇症）、性激素缺乏、胰岛素抵抗、生长激素/IGF-1不足，这些都扰乱了骨形成和吸收之间的平衡。衰老通过免疫衰老（例如，中性粒细胞吞噬功能受损，小胶质细胞衰老）和炎症加剧了这种双向相互作用，创造了一种促进退行性的环境，放大了这两种疾病。临床干预措施，如牙周治疗和微生物群调节，显示出减少全身性炎症和减缓AD进展的希望，尽管因果关系需要验证。未来的研究必须优先考虑纵向队列研究、病原体特异性机制调查和针对口腔-脑轴的转化策略，以开发针对老龄化人口的预防性干预措施。

Background

The primary cilium (PC) is a pivotal organelle for neuronal signaling and development, while tau tubulin kinase 2 (TTBK2) is a key initiator of ciliogenesis. However, the role of TTBK2 in spinal neurons during spinal cord injury (SCI) and subsequent neural repair remains unclear.

Methods

We manipulated TTBK2 expression in spinal neurons using adenovirus-mediated overexpression and knockdown in vitro. Transcriptomic profiling (RNA-sequencing) and RT-qPCR were employed to explore the potential regulatory pathways at the molecular level. In vivo, Ttbk2^fl/fl-Rosa-CreERT2^+/− conditional knockout mice were subjected to a spinal cord hemisection model. Behavioral assays, immunofluorescence, and biotinylated dextran amine (BDA) tracing were conducted to assess neuronal survival, axonal regeneration, and circuit reorganization.

Results

Here, we demonstrated that intact activity of TTBK2 in PC promoted neural survival, axonal regeneration, and neural circuit remodeling. However, loss of TTBK2 impaired PC function and hindered recovery after SCI.

Conclusions

These findings extend the role of PCs beyond neurodevelopment, demonstrating that the TTBK2–PC functions as an endogenous repair mechanism after SCI. Targeting this pathway may provide novel therapeutic strategies for enhancing neural regeneration.

背景：初级纤毛（PC）是神经元信号传导和发育的关键细胞器，而tau微管蛋白激酶2 （TTBK2）是纤毛发生的关键启动器。然而，在脊髓损伤（SCI）和随后的神经修复过程中，TTBK2在脊髓神经元中的作用尚不清楚。方法：利用腺病毒介导的TTBK2过表达和敲低技术，在体外调控TTBK2在脊髓神经元中的表达。利用转录组学分析（rna测序）和RT-qPCR在分子水平上探索潜在的调控途径。在体内，Ttbk2fl/fl-Rosa-CreERT2+/-条件敲除小鼠进行脊髓半切模型。通过行为分析、免疫荧光和生物素化右旋糖酐胺（BDA）示踪来评估神经元存活、轴突再生和回路重组。结果：在这里，我们证明了TTBK2在PC中的完整活性促进了神经存活、轴突再生和神经回路重塑。然而，TTBK2的缺失损害了脊髓损伤后的PC功能，阻碍了脊髓损伤后的恢复。结论：这些发现将pc的作用扩展到神经发育之外，表明TTBK2-PC在脊髓损伤后作为内源性修复机制发挥作用。靶向这一通路可能为增强神经再生提供新的治疗策略。

Aims

Intraventricular hemorrhage (IVH) has a high mortality and disability rate and poses significant clinical challenges, which often leads to hydrocephalus and neurological dysfunction. Emerging evidence implicates dysfunction of the glymphatic-meningeal lymphatic-deep cervical lymphatic system in the pathogenesis of post-IVH hydrocephalus. Therapeutic hypothermia (TH) holds promise for mitigating these sequelae. This study investigates the potential of TH to ameliorate IVH-induced hydrocephalus and neurological dysfunction, while elucidating its underlying mechanisms.

Methods

Rat models of IVH are established by intraventricular injection of autologous blood. TH, deep cervical lymph nodes (dCLNs) ligation, and intraperitoneal injection of AMPK inhibitor are used to intervene.

Results

In rat models of IVH, TH alleviates neurological dysfunction and attenuates hydrocephalus and pathology damage. TH protects physiological function and maintains normal structure of the glymphatic system. TH improves function and structure of the meningeal lymphatic system and promotes drainage of the deep cervical lymphatic system. TH upregulates RTN3, facilitates phosphorylation of AMPK, and suppresses ERS. All the above effects are reversed by ligation of dCLNs and AMPK inhibitor.

Conclusion

TH alleviates hydrocephalus and neurological dysfunction post IVH by enhancing drainage of the glymphatic-meningeal lymphatic-deep cervical lymphatic system. The RTN3/AMPK/ERS pathway may be the proposed mechanism mediating this effect. TH is expected to become a novel therapeutic strategy for IVH.

目的：脑室内出血（IVH）死亡率和致残率高，是临床面临的重大挑战，常导致脑积水和神经功能障碍。新出现的证据暗示淋巴-脑膜淋巴-颈深淋巴系统在ivh后脑积水发病机制中的功能障碍。治疗性低温（TH）有望减轻这些后遗症。本研究探讨了TH改善ivh诱导的脑积水和神经功能障碍的潜力，同时阐明了其潜在机制。方法：采用脑室内注射自体血建立大鼠IVH模型。采用TH、颈深淋巴结（dCLNs）结扎、AMPK抑制剂腹腔注射进行干预。结果：在IVH大鼠模型中，TH可减轻神经功能障碍，减轻脑积水和病理损害。TH保护生理功能，维持淋巴系统的正常结构。TH改善脑膜淋巴系统的功能和结构，促进颈深淋巴系统的引流。TH上调RTN3，促进AMPK磷酸化，抑制ERS。通过连接dcln和AMPK抑制剂，上述所有作用都被逆转。结论：TH可增强淋巴-脑膜淋巴-颈深淋巴系统引流，减轻IVH后脑积水和神经功能障碍。RTN3/AMPK/ERS通路可能是介导这种作用的机制。TH有望成为IVH的一种新的治疗策略。

Background

Parkinson's disease with motor complications (PD-MC) lacks effective diagnostic and therapeutic strategies. The perturbations of the gut microbiota and plasma metabolites are closely associated with the etiopathogenesis of PD. However, whether fecal microbiome dysbiosis and changed plasma metabolites are involved in PD progression, particularly in the development of PD-MC, is still unclear.

Methods

In this study, we performed an extensive multiomics analysis involving 108 PD patients for 16S rRNA gut microbiome profiling and 246 PD patients for plasma nontargeted metabolomics. Our findings revealed distinct gut microbiota and plasma metabolites associated with PD-MC. Utilizing these discriminative features, we developed a multivariate diagnostic model for PD-MC. The relationships between differential metabolites and microorganisms were evaluated using Spearman correlation analysis. Functional interpretation of the key metabolites was conducted through enrichment and pathway analysis, employing the KEGG and SMPDB databases.

Results

PD-MC patients had distinct gut microbial signatures as compared with PD without motor complications (PD-NMC) individuals and were increased in fecal Lactobacillus, Limosilactobacillus, Bifidobacterium, and Ligilactobacillus genera along with depleted Agathobacter. Moreover, metabolomic analysis revealed the differences in plasma 3-deoxysappanchalcone (3-DSC), 1,3-Dimethyluracil (1,3-DTl), Leucine, and N-Acetylisoleucine (N-AIL), Dodec-6-enoic acid (D-6-E), N-butyl Oleate (N-BO), and 4-hydroxyundecanoic acid (4-HUA) in PD-MC compared to PD-NMC. Spearman correlation analysis showed that the fecal microbiota aberrations in PD-MC patients were linked to plasma metabolic changes, indicating the association between key microbial populations and metabolomic profiles in PD-MC.

Conclusions

This study underscores the value of employing integrated multiomics profiling of the fecal microbiome and plasma metabolome to enhance the mechanistic understanding of PD-MC and to identify potential diagnostic biomarkers.

背景：帕金森病伴运动并发症（PD-MC）缺乏有效的诊断和治疗策略。肠道菌群和血浆代谢物的紊乱与PD的发病密切相关。然而，粪便微生物群失调和血浆代谢物的改变是否参与PD的进展，特别是PD- mc的发展，尚不清楚。方法：在这项研究中，我们对108名PD患者进行了广泛的多组学分析，进行了16S rRNA肠道微生物组分析，并对246名PD患者进行了血浆非靶向代谢组学分析。我们的研究结果揭示了与PD-MC相关的不同肠道微生物群和血浆代谢物。利用这些判别特征，我们开发了PD-MC的多变量诊断模型。采用Spearman相关分析评价差异代谢物与微生物之间的关系。利用KEGG和SMPDB数据库，通过富集和通路分析对关键代谢物进行功能解释。结果：与没有运动并发症的PD- nmc患者相比，PD- mc患者具有明显的肠道微生物特征，并且粪便中乳酸杆菌、乳酸杆菌、双歧杆菌和乳酸杆菌属的数量增加，同时Agathobacter的数量减少。此外，代谢组学分析显示PD-MC与PD-NMC血浆中3-脱氧葡查尔酮（3-DSC）、1,3-二甲基尿嘧啶（1,3- dtl）、亮氨酸和n -乙酰异亮氨酸（N-AIL）、十二-6-烯酸（D-6-E）、n -丁基油酸（N-BO）和4-羟基十一烷酸（4-HUA）的差异。Spearman相关分析显示，PD-MC患者的粪便微生物群畸变与血浆代谢变化有关，表明PD-MC患者的关键微生物群与代谢组学特征之间存在关联。结论：本研究强调了利用粪便微生物组和血浆代谢组的综合多组学分析来增强PD-MC的机制理解和识别潜在的诊断生物标志物的价值。

Background

Plasma markers of neuronal injury in Creutzfeldt–Jakob disease (CJD) are established, but peripheral biomarkers reflecting glial activation, synaptic dysfunction, and vascular impairment remain less explored. We systematically assessed these markers in symptomatic CJD and asymptomatic PRNP mutation carriers to improve diagnosis and identify early pathophysiology.

Methods

This prospective cohort study recruited CJD, frontotemporal dementia (FTD), healthy controls (HCs), and preclinical familial CJD pedigrees. Sixteen plasma proteins representing neuronal injury, glial activation, synaptic function, and vascular/BBB integrity were measured. Analyses included group differences, discriminative performance, clinical/imaging correlations, and longitudinal trajectories.

Results

We enrolled 130 CJD patients, 145 FTD, 70 HCs, 16 asymptomatic PRNP carriers (4–6 years follow-up, 4 converters), and 16 non-carrier family controls. In symptomatic CJD, plasma NfL, t-tau, and GFAP were strongly elevated, each showing excellent discriminative performance (AUCs > 0.93 vs. HCs and > 0.82 vs. FTD). We also observed alterations in vascular/BBB markers, with VCAM-1 levels elevated and significantly associated with both clinical decline and DWI hyperintensity. In asymptomatic carriers, biomarker levels remained largely normal and stable preclinically. Notably, two G114V carriers showed mild pre-symptomatic elevations in NfL and GFAP, and one exhibited a slight VCAM-1 increase before clinical onset; all changes exceeded the 90th percentile of control values. E200K and T188K carriers showed no pre-onset changes.

Conclusions

背景：克雅氏病（Creutzfeldt-Jakob disease， CJD）神经元损伤的血浆标志物已经建立，但反映神经胶质激活、突触功能障碍和血管损伤的外周生物标志物仍然很少被探索。我们在有症状的CJD和无症状的PRNP突变携带者中系统地评估了这些标记物，以提高诊断和识别早期病理生理。方法：这项前瞻性队列研究招募了克雅氏病、额颞叶痴呆（FTD）、健康对照（hc）和临床前家族性克雅氏病谱系。测量了代表神经元损伤、神经胶质活化、突触功能和血管/血脑屏障完整性的16种血浆蛋白。分析包括组间差异、鉴别表现、临床/影像学相关性和纵向轨迹。结果：我们招募了130名CJD患者，145名FTD患者，70名hc患者，16名无症状PRNP携带者（随访4-6年，4名转化者）和16名非携带者家族对照。在有症状的CJD中，血浆NfL、t-tau和GFAP均显著升高，分别表现出优异的鉴别性能（auc为> 0.93 vs. hc, > 0.82 vs. FTD）。我们还观察到血管/血脑屏障标志物的改变，VCAM-1水平升高，与临床衰退和DWI高强度显著相关。在无症状携带者中，生物标志物水平在临床前基本保持正常和稳定。值得注意的是，两名G114V携带者在症状前表现出轻微的NfL和GFAP升高，一名在临床发病前表现出轻微的VCAM-1升高；所有变化均超过控制值的第90个百分位数。E200K和T188K携带者未见发病前变化。结论：血浆生物标志物可能反映了克雅氏病的多系统参与，神经元标志物具有很强的鉴别潜力，血管蛋白表明可能存在血脑屏障功能障碍。在无症状携带者中，轻微的变化可能只发生在那些进展相对缓慢的突变的发病附近。

Background

Peripheral neuropathy (PN) is a common consequence of peripheral nervous system (PNS) disorders, yet its effective treatment remains a significant clinical challenge. Pyroptosis, an inflammatory form of programmed cell death (PCD) triggered by gasdermin A–E (GSDMA-E), contributes to the pathogenesis of PN and represents a promising therapeutic target. While reviews of pyroptosis in other diseases are extensive, comprehensive reviews focusing on PN are lacking.

Method

We systematically searched PubMed, Scopus, Web of Science, and Google Scholar (1986–2025). Only original studies investigating pyroptosis in PN were included.

Results

This review first consolidates established evidence, highlighting a context-dependent dual role of pyroptosis in PN. Its detrimental effects in chronic pain involve canonical (caspase-1/GSDMD) or noncanonical pathways (e.g., caspase-4/5/11/GSDMD, caspase-3/GSDME, caspase-8/GSDMC), often initiated by inflammasomes (e.g., NOD-like receptor family pyrin domain containing 3 [NLRP3]). Conversely, its beneficial, tumoricidal role is leveraged in neuroblastoma. Preclinically, diverse inhibitors—including NLRP3 inhibitors (e.g., MCC950), caspase-1 inhibitors (e.g., VX-765), and P2X7R antagonists (e.g., Brilliant Blue G)—alleviate pain and promote nerve repair, while pyroptosis inducers (e.g., axitinib) combat chemoresistant tumors. We then identify critical knowledge gaps and emerging frontiers. The roles of most gasdermins (GSDMA, GSDMB, GSDMC) in PN are unknown. We explore the emerging concept of PANoptosis (crosstalk among pyroptosis, apoptosis, and necroptosis) as a novel conceptual framework for PNS pathologies, where shared molecular hubs may amplify neuroinflammation. Furthermore, despite promising strategies like combination therapy and drug repurposing, a significant translational gap exists, with no current clinical trials specifically targeting pyroptosis for PN.

Conclusion and Perspective

Targeting pyroptosis is a novel therapeutic avenue for PN. This review synthesizes current mechanistic understanding, evaluates preclinical therapeutic strategies, and delineates crucial future directions, including elucidating gasdermin diversity, validating PANoptosis, and bridging the translational divide, thereby accelerating their application for patients suffering from PN.

背景：周围神经病变（PN）是周围神经系统（PNS）疾病的常见后果，但其有效治疗仍然是一个重大的临床挑战。焦亡是一种由气皮蛋白a - e （GSDMA-E）引发的程序性细胞死亡（PCD）的炎症形式，有助于PN的发病机制，是一个有希望的治疗靶点。虽然对其他疾病的焦亡的综述很广泛，但缺乏对PN的全面综述。方法：系统检索PubMed、Scopus、Web of Science和谷歌Scholar（1986-2025）。仅纳入了研究PN焦亡的原始研究。结果：这篇综述首先巩固了已有的证据，强调了焦亡在PN中依赖于环境的双重作用。它在慢性疼痛中的有害作用涉及典型（caspase-1/GSDMD）或非典型途径（如caspase-4/5/11/GSDMD、caspase-3/GSDME、caspase-8/GSDMC），通常由炎症小体（如nod样受体家族pyrin结构域3 [NLRP3]）启动。相反，其有益的杀瘤作用在神经母细胞瘤中发挥作用。临床前，多种抑制剂——包括NLRP3抑制剂（如MCC950）、caspase-1抑制剂（如VX-765）和P2X7R拮抗剂（如Brilliant Blue G）——可以缓解疼痛并促进神经修复，而焦死诱导剂（如阿西替尼）可以对抗化疗耐药肿瘤。然后，我们确定关键的知识差距和新兴的前沿。大多数gasdermins （GSDMA， GSDMB， GSDMC）在PN中的作用尚不清楚。我们将PANoptosis（焦亡、凋亡和坏死之间的串扰）这一新兴概念作为PNS病理的新概念框架进行探讨，其中共享的分子中心可能会放大神经炎症。此外，尽管联合治疗和药物再利用等有希望的策略，但存在显著的翻译差距，目前没有专门针对焦亡治疗PN的临床试验。结论与展望：靶向性焦亡是治疗PN的新途径。这篇综述综合了目前的机制理解，评估了临床前治疗策略，并描绘了关键的未来方向，包括阐明gasdermin多样性，验证PANoptosis，弥合翻译鸿沟，从而加速它们在PN患者中的应用。

Background

Supratentorial focal lesions following ischemic stroke can lead to crossed cerebellar diaschisis (CCD). However, it remains unclear how CCD affects the functional connectivity between the cerebellum and the rest of the brain in ischemic stroke patients.

Methods

This case–control study involved resting-state fMRI data from 65 patients with basal ganglia ischemic stroke (Stroke) and 72 healthy controls (HC). Cerebral, cerebellar, and cerebrocerebellar inter-module functional connectivity in both 7-module and 17-module conditions were calculated and compared between the Stroke and HC groups. Spearman correlation analyses were further conducted to examine the relationships between connectivity alterations and both stroke severity and lesion size in Stroke patients.

Results

The Stroke patients exhibited disrupted inter-module functional connectivity, characterized by increased intra-hemispheric and decreased inter-hemispheric connectivity between cerebral modules, increased inter-module connectivity in the cerebellum, and reduced connectivity between ipsilesional cerebral modules and cerebellar modules while increasing connectivity between contralesional cerebral modules and cerebellar modules. Moreover, these connectivity changes, particularly disruptions in the cerebellar connectome, may be associated with lesion size and stroke severity in Stroke patients.

Conclusions

These findings highlight the importance of cerebellar connectome disruptions in ischemic stroke, which may provide valuable insights into the disease's underlying brain mechanisms.

背景：缺血性脑卒中后幕上局灶性病变可导致交叉小脑水溶（CCD）。然而，目前尚不清楚CCD如何影响缺血性中风患者小脑和大脑其他部分之间的功能连接。方法：本病例对照研究包括65例基底节区缺血性脑卒中（卒中）患者和72例健康对照（HC）的静息状态fMRI数据。计算并比较卒中组和HC组在7模块和17模块条件下的大脑、小脑和脑小脑模块间功能连通性。进一步进行Spearman相关分析，检验脑卒中患者连通性改变与脑卒中严重程度和病变大小之间的关系。结果：脑卒中患者表现为脑模块间功能连接中断，表现为脑模块间半球内连接增加，半球间连接减少，小脑模块间连接增加，同侧脑模块与小脑模块间连接减少，对侧脑模块与小脑模块间连接增加。此外，这些连通性的改变，特别是小脑连接组的破坏，可能与中风患者的病变大小和中风严重程度有关。结论：这些发现强调了缺血性卒中中小脑连接体中断的重要性，这可能为该疾病的潜在脑机制提供有价值的见解。

Objective

This study aimed to systematically map the functional organization of the cingulate gyrus using cortical electrical stimulation (CES) guided by the Brainnetome Atlas.

Methods

We retrospectively analyzed CES data from 234 patients with drug-resistant epilepsy who underwent stereoelectroencephalography (SEEG) implantation in the cingulate cortex. A total of 1141 stimulation sites across seven cingulate subregions (A23d, A24rv, A32p, A23v, A24cd, A23c, A32sg) were examined. Responses were categorized into somatosensory, motor, autonomic, vestibular, visual, emotional, memory, and pain-related phenomena.

Results

Key findings included: (1) Somatosensory responses (n = 99) were widely distributed, with motor responses localized to middle-posterior subregions (A23c/A24rv/A24cd); (2) Autonomic (n = 58) and emotional (n = 15) responses showed broad distribution, with ventral MCC (A24rv) as an affective hub; (3) Pain responses (n = 30) involved both anterior (affective) and posterior (spatial) subregions; (4) Memory deficits (n = 8) specifically localized to posterior cingulate (A23d); (5) Visual (n = 13) and vestibular (n = 51) responses clustered in posterior and middle-posterior regions, respectively.

Conclusion

This study provides a systematic functional mapping of the cingulate gyrus using the Brainnetome Atlas, demonstrating its integrated role in diverse neurological functions. The findings advance understanding of cingulate pathophysiology and have implications for surgical planning in epilepsy.

Aims

This study aims to evaluate 5-(but-1-en-1-yl)-1,2,3-trimethoxybenzene (BETMB) as a novel dual-target anti-seizure agent for refractory epilepsy and elucidate the synergistic neuroelectrophysiological mechanism between Na_V channels and GABA_A receptors.

Methods

Whole-cell patch-clamp recordings characterized BETMB's dual-target activity. Antiseizure efficacy was assessed in maximal electroshock (MES), pentylenetetrazole (PTZ), and kainic acid (KA) models. Cognitive function in chronic KA mice was evaluated using the Morris water maze (MWM). Histopathological, immunohistochemical, and Western blot analyses explored neuroprotection. Synergy between Na_V and GABA_AR modulation was systematically investigated using both an in vitro Mg²⁺-free model of neuronal hyperexcitability and an in silico model of cortical spreading depolarization (CSD).

Results

BETMB acted as a GABA_AR positive allosteric modulator (EC₅₀ = 93.2 μM) and a state-dependent Na_V blocker (K_I = 1.9 μM). It significantly suppressed seizures across models, improved cognition in chronic epilepsy, and modulated downstream expression of GABRA1, NR2B, and BDNF-pAKT-CREB signaling. Synergistic Na_V and GABA_AR modulation completely abolished ictal-like discharges in Mg²⁺-free cellular models and prevented CSD initiation in computational simulations.

Conclusion

BETMB is a promising dual-target therapy for refractory epilepsy, supported by the first electrophysiological evidence that dual modulation of GABA_AR and Na_V synergistically suppresses neuronal hyperexcitability. Beyond epilepsy, this finding may also extend to CSD-related conditions such as stroke, traumatic brain injury, and migraine.

目的：本研究旨在评价5-（丁-1-烯-1-基）-1,2,3-三甲氧基苯（BETMB）作为一种新型双靶点抗难治性癫痫药物的作用，并阐明NaV通道与GABAA受体之间的协同神经电生理机制。方法：全细胞膜片钳记录表征BETMB的双靶点活性。在最大电击（MES）、戊四唑（PTZ）和kainic酸（KA）模型中评估抗癫痫效果。采用Morris水迷宫（MWM）评价慢性KA小鼠的认知功能。组织病理学、免疫组织化学和Western blot分析探讨了神经保护作用。通过体外无Mg2+神经元高兴奋性模型和皮质扩张性去极化（CSD）模型，系统地研究了NaV和GABAAR调节之间的协同作用。结果：BETMB具有GABAAR阳性变构调节剂（EC50 = 93.2 μM）和状态依赖性NaV阻滞剂（KI = 1.9 μM）的作用。它显著抑制了所有模型的癫痫发作，改善了慢性癫痫的认知，并调节了GABRA1、NR2B和BDNF-pAKT-CREB信号的下游表达。协同NaV和GABAAR调制完全消除了无Mg2+细胞模型中的初始样放电，并在计算模拟中阻止了CSD的启动。结论：BETMB是治疗难治性癫痫的一种很有前景的双靶点疗法，首次得到GABAAR和NaV双调节协同抑制神经元高兴奋性的电生理证据支持。除了癫痫，这一发现也可能延伸到与脑脊病相关的疾病，如中风、创伤性脑损伤和偏头痛。

Background

Postoperative delirium (POD) is a serious complication in elderly patients, associated with prolonged recovery and adverse outcomes. Recent evidence links POD to mitochondrial dysfunction. While intermittent fasting (IF) has been shown to enhance mitochondrial function and exert neuroprotective effects, potentially through gut microbiota modulation, its ability to prevent POD and the underlying mechanisms remain unclear.

Methods

We examined the effects of preoperative IF on delirium-like behavior in aged mice following anesthesia/surgery. Assessments included neurobehavioral tests, gut microbiota composition, fecal shortchain fatty acids (SCFAs), hippocampal synaptic and mitochondrial ultrastructure via transmission electron microscopy, mitochondrial function, and related molecular markers. To establish causality, fecal microbiota transplantation and SCFA supplementation experiments were conducted.

Results

Preoperative IF significantly attenuated anesthesia/surgery-induced delirium-like behaviors. Mechanistically, IF reshaped the gut microbiota and preserved SCFA levels, which collectively maintained hippocampal mitochondrial homeostasis. Both fecal microbiota transplantation and SCFA supplementation replicated the protective effects of IF, confirming the causal role of gut microbiota and its metabolites.

Conclusion

These findings demonstrate that preoperative intermittent fasting mitigates delirium-like behavior by modulating the gut microbiota–SCFA–mitochondrial axis, highlighting its potential as a non-pharmacological strategy to enhance neurocognitive resilience and prevent POD in elderly surgical patients.

背景：术后谵妄（POD）是老年患者的严重并发症，与恢复时间长和不良后果相关。最近的证据表明POD与线粒体功能障碍有关。虽然间歇性禁食（IF）已被证明可以增强线粒体功能并发挥神经保护作用，可能通过调节肠道微生物群，但其预防POD的能力及其潜在机制尚不清楚。方法：我们检查了术前IF对麻醉/手术后老年小鼠谵妄样行为的影响。评估包括神经行为测试、肠道微生物群组成、粪便短链脂肪酸（SCFAs）、海马突触和线粒体超微结构（透射电镜）、线粒体功能和相关分子标记。为了建立因果关系，进行了粪便微生物群移植和SCFA补充实验。结果：术前IF明显减轻麻醉/手术引起的谵妄样行为。从机制上讲，IF重塑了肠道微生物群并保持了SCFA水平，这共同维持了海马线粒体的稳态。粪便微生物群移植和SCFA补充都复制了IF的保护作用，证实了肠道微生物群及其代谢物的因果作用。结论：这些研究结果表明，术前间歇性禁食通过调节肠道微生物群- scfa -线粒体轴来减轻谵妄样行为，突出了其作为增强老年外科患者神经认知弹性和预防POD的非药物策略的潜力。
