Our previous study proved that Lithocarpus polystachyus Rehd. aqueous extract (sweet tea aqueous extract, STAE) effectively inhibits hydrogen peroxide‐induced neuronal cell injury. However, it is not clear whether STAE can protect against AD, and its underlying mechanisms are still uncertain. Therefore, the present study was designed to evaluate the possible behavioral and neurochemical effects of STAE on Aβ25‐35‐induced AD rats administered STAE (20, 40, 80 mg/mL) for 14 days. We showed that STAE administration significantly and dose‐dependently ameliorated the cognitive deficits in the AD rat models, assessed in the Morris water maze (MWM) test, Y‐maze test, and novel object recognition (NOR) test. The results of hematoxylin and eosin (H&E) staining and Nissl staining showed that after treatment with STAE, the pathological damage to the hippocampal CA1, CA3, and dentate gyrus (DG) neurons of rats was significantly improved. Furthermore, STAE dose‐dependently inhibited microglia and astrocyte activation in the hippocampus of rats accompanied by increased protein expression of silent mating‐type information regulation 2 homolog 6 (SIRT6) and decreased protein expression of nod‐like receptor thermal protein domain‐associated protein 3 (NLRP3) and its downstream pyroptosis‐related genes after following Aβ25‐35. In summary, our findings indicate that STAE effectively inhibits Aβ25‐35‐induced learning and memory impairment in rats, and the mechanism is, at least partially, related to the regulation of SIRT6/NLRP3 signaling pathway.","PeriodicalId":94030,"journal":{"name":"Ibrain","volume":"21 9","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141271712","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It results in associated neurological abnormalities due to a variety of factors, including disruption of cerebral arterial blood flow, hypoxia, and ischemic necrosis of local brain tissues. The neurovascular unit (NVU) is a dynamic structural complex that consists of neurons, glial cells, pericytes, vascular endothelial cells, and the extracellular matrix. Many cells work together to preserve the integrity of the central nervous system (CNS) under physiological conditions. However, following ischemic stroke, NVU homeostasis is disrupted along with the development of tissue ischemia and hypoxia, as well as impaired interactions between various components of the NVU. Collectively, the changes result in increased blood–brain barrier permeability, neuronal dysfunction, and functional destruction of nerve conduction bundles, ultimately leading to the clinical manifestation of neurological deficits including motor, cognitive, and speech impairments that hinder the rehabilitation process. In recent years, with continuously expanding research on ischemic cerebrovascular disease, the role of interconnections between different cells in the NVU in ischemic stroke has received increasing attention. To describe new concepts for the prevention and treatment of ischemic cerebrovascular illnesses, this article reviews the interplay between NVU in the pathogenesis of ischemic stroke.","PeriodicalId":94030,"journal":{"name":"Ibrain","volume":"27 8","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141272050","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

String database and Cytoscape3.7.2 were used to perform the protein–protein interaction (PPI) and construct genes network. The key target genes were analyzed using gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG). Then, the aging-related genes were verified by reverse-transcription polymerase chain reaction in SAM-P/8 mice, and performed molecular docking with the main components of PNS. Moreover, it produced cluster between Hub genes and differential genes. A total of 169 crossover genes were obtained, and the results of GO and KEGG indicated that the antiaging effect of PNS was mediated by apoptosis, cancer, and neurodegeneration and that five of the eight Hub genes had good binding activity with the main components of PNS. In addition, animal experiments reported that MAP2, MAPKK4, RAB6A, and Sortilin-1 have different levels of expression in the brain tissues of aging mice, and bind well docking with the main active components of PNS. However, there was no crossover between the 169 PNS intersecting genes and the four differential genes, while they yielded a link from PPI in which MAP2K4 was only linked to AKT1 and CASP3; MAP2 was only linked to AKT1 and CASP3; RAB6A was only linked to AKT1; but Sortlin-1 did not link to the Hub genes. In summary, the antiaging effect of PNS is associated with the eight Hub genes and four differential genes.

Ongoing efforts focus on implementing diverse strategies to mitigate the adverse effects of neurodegeneration, with the goal of decelerating the pathology progression. Notably, in recent years, it has emerged that the use of nanoparticles (NPs), particularly those obtained through green chemical processes, could constitute a promising therapeutic approach. Green NPs, exclusively sourced from phytochemicals, are deemed safer compared to NPs synthetized through conventional chemical route. In this study, the effects of green chemistry-derived silver NPs (AgNPs) were assessed in neuroblastoma cells, SHSY-5Y, which are considered a pivotal model for investigating neurodegenerative diseases. Specifically, we used two different concentrations (0.5 and 1 µM) of AgNPs and two time points (24 and 48 h) to evaluate the impact on neuroblastoma cells by observing viability reduction and intracellular calcium production, especially using 1 µM at 48 h. Furthermore, investigation using atomic force microscopy (AFM) unveiled an alteration in Young's modulus due to the reorganization of cortical actin following exposure to green AgNPs. This evidence was further corroborated by confocal microscopy acquisitions as well as coherency and density analyses on actin fibers. Our in vitro findings suggest the potential efficacy of green AgNPs against neurodegeneration; therefore, further in vivo studies are imperative to optimize possible therapeutic protocols.","PeriodicalId":94030,"journal":{"name":"Ibrain","volume":"10 2","pages":"123-133"},"PeriodicalIF":0.0,"publicationDate":"2024-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ibra.12157","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141107082","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There is uncertainty regarding whether clearing Aβ is beneficial or harmful to cognitive function. This question has been a central topic of research, especially given the lack of success in developing Aβ-targeted drugs for AD. However, with the Food and Drug Administration's approval of Lecanemab as the first anti-Aβ medication in July 2023, there is a significant shift in perspective on the potential of Aβ as a therapeutic target for AD. In light of this advancement, this review aims to illustrate and consolidate the molecular structural attributes and pathological ramifications of Aβ. Furthermore, it elucidates the determinants influencing its expression levels while delineating the gamut of extant Aβ-targeted pharmacotherapies that have been subjected to clinical or preclinical evaluation. Subsequently, a comprehensive analysis is presented, dissecting the research landscape of Aβ across the domains above, culminating in the presentation of informed perspectives. Concluding reflections contemplate the supplementary advantages conferred by nanoparticle constructs, conceptualized within the framework of multivalent theory, within the milieu of AD diagnosis and therapeutic intervention, supplementing conventional modalities.","PeriodicalId":94030,"journal":{"name":"Ibrain","volume":"10 3","pages":"266-289"},"PeriodicalIF":0.0,"publicationDate":"2024-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ibra.12155","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141103669","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Previous studies mostly used ultrasound-guided out-of-plane puncture for CMBB, while this prospective study was designed to investigate the efficacy of ultrasound-guided in-plane puncture, specifically focusing on the new target of CMBB for cervical pain. This study includes two parts: the accuracy study (N = 15, CMBB was completed by ultrasound and confirmed by computed tomography [CT], in which a good distribution percentage of the analgesic solution was observed) and the efficacy study (N = 40, CMBB was completed by ultrasound or CT, while the proportion of pain relief (numerical rating scale) decrease by more than 50% postoperatively was analyzed). The results showed that the good distribution percentage of the analgesic solution was 97.8%. Furthermore, in the early period (30 min and 2 h postoperatively), the proportion of patients with pain relief was lower in the ultrasound group than that in the CT group, especially at 2 h postoperatively (52% vs. 94%). However, at 24 h postoperatively and later, the proportion of patients with pain relief gradually stabilized to about 60%–70%, and lasted for about 2 weeks to 1 month. Therefore, the new target for CMBB, guided by ultrasound in-plane, offers high visibility and accuracy. A single CMBB performed under ultrasound guidance resulted in pain relief comparable to that of a CT-guided procedure (1 day to 1 month postoperatively). This study indicated that CMBB guided by ultrasound in-plane could be regarded as a promising approach for treatment of cervicogenic pain.","PeriodicalId":94030,"journal":{"name":"Ibrain","volume":"10 1","pages":"34-45"},"PeriodicalIF":0.0,"publicationDate":"2024-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ibra.12151","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140235155","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The brain, a highly sophisticated organ, orchestrates a diverse array of physiological processes encompassing motor control, sensory perception, cognition, emotion, and the regulation of vital functions, such as heartbeat, respiration, and hormonal equilibrium. A notable attribute of neurological diseases manifests as the depletion of neurons and the occurrence of tissue necrosis subsequent to injury. The transplantation of neural stem cells (NSCs) into the brain exhibits the potential for the replacement of lost neurons and the reconstruction of neural circuits. Furthermore, the transplantation of other types of cells in alternative locations can secrete nutritional factors that indirectly contribute to the restoration of nervous system equilibrium and the mitigation of neural inflammation. This review summarized a comprehensive investigation into the role of NSCs, hematopoietic stem cells, mesenchymal stem cells, and support cells like astrocytes and microglia in alleviating neurological deficits after cell infusion. Moreover, a thorough assessment was undertaken to discuss extant constraints in cellular transplantation therapies, concurrently delineating indispensable model-based methodologies, specifically on organoids, which were essential for guiding prospective research initiatives in this specialized field.","PeriodicalId":94030,"journal":{"name":"Ibrain","volume":"10 1","pages":"93-105"},"PeriodicalIF":0.0,"publicationDate":"2024-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ibra.12152","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140250044","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
