Sleep apnea syndrome (SAS) is a prevalent disorder characterized by recurrent respiratory pauses during sleep; however, the neural mechanisms governing respiratory stability remain poorly understood. In this study, we identify the ratio of sigh expiratory volume to eupneic expiratory volume as a potential predictor of post-sigh apnea in susceptible C57BL/6J mice. We demonstrate that leptin signaling within the nucleus tractus solitarius (NTS) is critical for maintaining respiratory drive and suppressing apnea. Chemogenetic activation of Leptin receptor b-expressing NTS (NTSLepRb) neurons significantly reduced apnea incidence, whereas their ablation exacerbated respiratory dysfunction. Moreover, NTSLepRb neurons mediate these effects through anatomically and functionally segregated projections to the dorsomedial hypothalamus and the lateral parabrachial nucleus. These findings define a specific leptin-mediated brainstem circuit that stabilizes respiratory output, providing new mechanistic insights and potential therapeutic targets for sleep-disordered breathing.
OBJECTIVE:The globus pallidus externa (GPe) is involved in mediating physiological functions and contains two types of neurons: Forkhead box protein P2-expressing (GPeFoxP2) neurons which inhibit motor, and parvalbumin-expressing (GPePV) neurons which improve motor. The functional complexity of the GPe, directly linked to its neuronal heterogeneity, necessitates exploring the neuroanatomical circuits of its distinct neuron types as a foundation for functional research. METHODS:In this study, we employed specific, modified rabies viruses and adeno-associated viruses to investigate the monosynaptic inputs of GPeFoxP2 and GPePV neurons. RESULTS:We found that the input projections to both types of neurons are widespread, including the cortex, subcortical structures, amygdala, thalamus, hypothalamus, and brainstem. These inputs exhibit significant similarity, with 49 nuclei simultaneously innervating both types of neurons. However, GPePV neurons receive a lower proportion of inputs from the cortex and a higher proportion of inputs from the thalamus, compared to GPeFoxP2 neurons. Clustering analysis indicates that GPeFoxP2 neurons receive extensive afferent inputs from four nuclear clusters in the brain, whereas GPePV neurons receive afferent inputs from only three clusters, suggesting GPeFoxP2 neurons may be involved in more diverse functional regulations than GPePV. CONCLUSION:Collectively, our results reveal the similarities and differences in the input projections to the two types of neurons in the GPe and lay the neuroanatomic groundwork for further studies to explore the critical physiological functions of GPe.
Central sleep apnea (CSA), characterized by unstable ventilatory control during sleep, poses significant health risks, particularly in patients with cardiovascular comorbidities. This bibliometric analysis evaluated 1,687 CSA-related publications (2004–2025) from the Web of Science Core Collection. Annual publications surged post-2016, peaking in 2021 (115 articles), reflecting growing research interest. The U.S. and Germany dominated contributions, with American Journal of Respiratory and Critical Care Medicine as the top journal. Keyword analysis revealed three focal areas: CSA-heart failure interactions (e.g., mortality, ejection fraction), CSA mechanisms (e.g., hypercapnia, chemosensitivity), and clinical management (e.g., adaptive servo-ventilation, phrenic nerve stimulation). Emerging trends include pediatric CSA, pathophysiology, and AI-driven diagnostics. International collaboration and multidisciplinary approaches are critical for advancing CSA research. Limitations include database constraints and evolving literature. This study maps CSA research trends, highlights gaps, and guides future investigations into mechanisms, biomarkers, and personalized therapies.
High entropy alloys have garnered considerable attention within the realm of electrocatalysis. This study introduces a Ni-Fe-Co-Mn-V high entropy alloy (NFCMV-HEA) electrocatalyst fabricated on a nickel foam substrate via a facile and controlled one-step electrodeposition process. Remarkably, in a 1 M KOH electrolyte, the NFCMV-HEA catalyst exhibits exceptional catalytic efficiency, needing only a mere 7 mV overpotential for hydrogen evolution to reach a current density of 10 mA cm- 2 . Furthermore, the Tafel slope is relatively low at 147.5 mV dec- 1 , suggesting favorable kinetics. The catalyst maintains its performance stability even following an extensive 90 h durability assessment. Further elucidation reveals that the nano-scale resberry-like micro-convex surface structure of the electrodeposited HEA yields a profusion of electrochemically active sites, synergized with the distinctive cocktail effect intrinsic to HEAs, thereby endowing the catalyst with exceptional HER electrocatalytic prowess.
OBJECTIVE:Phenylethanolamine N-methyltransferase (PNMT)-expressing neurons in the nucleus tractus solitarii (NTS) contribute to the regulation of autonomic functions. However, the neural circuits linking these neurons to other brain regions remain unclear. This study aims to investigate the connectivity mechanisms of the PNMT-expressing neurons in the NTS (NTSPNMT neurons). METHODS:The methodologies employed in this study included a modified rabies virus-based retrograde neural tracing technique, conventional viral anterograde tracing, and immunohistochemical staining procedures. RESULTS:A total of 43 upstream nuclei projecting to NTSPNMT neurons were identified, spanning several key brain regions including the medulla oblongata, pons, midbrain, cerebellum, diencephalon, and telencephalon. Notably, dense projections to the NTSPNMT neurons were observed from the central amygdaloid nucleus, paraventricular nucleus of the hypothalamus, area postrema, and the gigantocellular reticular nucleus. In contrast, the ventrolateral medulla, lateral parabrachial nucleus, and lateral hypothalamic area were identified as the primary destinations for axon terminals originating from NTSPNMT neurons. Additionally, reciprocal projections were evident among 21 nuclei, primarily situated within the medulla oblongata. CONCLUSION:Our research findings demonstrate that NTSPNMT neurons form extensive connections with numerous nuclei, emphasizing their essential role in the homeostatic regulation of vital autonomic functions.
AIMS:To identify whether and how a younger systemic internal milieu alleviates acute kidney injury (AKI) in grafts after kidney transplantation.MATERIALS AND METHODS:We conducted an allogenic heterotopic rat kidney transplantation model with young and adult recipients receiving similar donor kidneys. We evaluated the renal function, histological damage, apoptosis, dedifferentiation, proliferation, hub regulating cytokines, and signaling pathways involved in young and adult recipients based on transcriptomics, proteomics, and experimental validation. We also validated the protective effect and mechanism of interleukin-13 (IL-13) on tubular epithelial cell injury induced by transplantation in vivo and by cisplatin in vitro.KEY FINDINGS:Compared with adult recipients, the young recipients had lower levels of renal histological damage and apoptosis, while had higher levels of dedifferentiation and proliferation. Serum IL-13 levels were higher in young recipients both before and after surgery. Pretreating with IL-13 decreased apoptosis and promoted regeneration in injured rat tubular epithelial cells induced by cisplatin, while this effect can be counteracted by a JAK2 and STAT3 specific inhibitor, AG490. Recipients pretreated with IL-13 also had lower levels of histological damage and improved renal function.SIGNIFICANCE:Higher levels of IL-13 in young recipients ameliorates tubular epithelial cell apoptosis and promotes regeneration via activating the JAK-STAT signaling pathway both in vivo and in vitro. Our results suggest that IL-13 is a promising therapeutic strategy for alleviating AKI. The therapeutic potential of IL-13 in injury repair and immune regulation deserves further evaluation and clinical consideration.
High-entropy alloy electrocatalysts can better regulate the electronic structure and provide opportunities for catalytic reactions to a greater extent due to the synergistic effect between its multi-metal components. In this paper, Ni-Fe-Co-Mn-Sn high-entropy alloy (NFCMS-HEA) electrocatalysts were successfully prepared by one-step electrodeposition method on nickel foam substrate. The introduction of Sn atoms, which have significantly different atomic sizes compared to other elements, results in an increased degree of lattice distortion in the HEA and a highly open multi-level nanostructured surface, thereby endowing the catalyst with exceptionally high hydrogen evolution performance. The optimized NFCMS-HEA electrocatalyst exhibits a low overpotential of 4.3 mV at a current density of 10 mA cm- 2 and a low Tafel slope of 59.7 mV dec- 1 in 1 M KOH solution. In addition, it maintains a superior stability of electrolysis for more than 100 h in 1 M KOH solution. In conclusion, the present study offers prospects for the preparation of HER high-entropy catalysts by one-step electrodeposition.
The central leptin signaling system has been found to facilitate breathing and is linked to obesity-related hypoventilation. Activation of leptin signaling in the nucleus tractus solitarii (NTS) and retrotrapezoid nucleus (RTN) enhances respiratory drive. In this study, we investigated how medullary leptin signaling contributes to hypoventilation and whether respective deletion of SOCS3 in the NTS and RTN could mitigate hypoventilation in diet-induced obesity (DIO) male mice. Our findings revealed a decrease in the number of CO2-activated NTS neurons and downregulation of acid-sensing ion channels in DIO mice compared to lean control mice. Moreover, NTS leptin signaling was disrupted, as evidenced by the downregulation of phosphorylated STAT3 and the upregulation of SOCS3 in DIO mice. Importantly, deleting SOCS3 in the NTS and RTN significantly improved the diminished hypercapnic ventilatory response in DIO mice. In conclusion, our study suggests that disrupted medullary leptin signaling contributes to obesity-related hypoventilation, and inhibiting the upregulated SOCS3 in the NTS and RTN can alleviate this condition.
The nucleus tractus solitarii (NTS) is the primary central station that integrates visceral afferent information and regulates respiratory, gastrointestinal, cardiovascular, and other physiological functions. Leptin receptor b (LepRb)-expressing neurons of the NTS (NTSLepRb neurons) are implicated in central respiration regulation, respiratory facilitation, and respiratory drive enhancement. Furthermore, LepRb dysfunction is involved in obesity, insulin resistance, and sleep-disordered breathing. However, the monosynaptic inputs and outputs of NTSLepRb neurons in whole-brain mapping remain to be elucidated. Therefore, the exploration of its whole-brain connection system may provide strong support for comprehensively understanding the physiological and pathological functions of NTSLepRb neurons. In the present study, we used a cell type-specific, modified rabies virus and adeno-associated virus with the Cre-loxp system to map monosynaptic inputs and outputs of NTSLepRb neurons in LepRb-Cre mice. The results showed that NTSLepRb neurons received inputs from 48 nuclei in the whole brain from five brain regions, including especially the medulla. We found that NTSLepRb neurons received inputs from nuclei associated with respiration, such as the pre-Bötzinger complex, ambiguus nucleus, and parabrachial nucleus. Interestingly, some brain areas related to cardiovascular regulation-i.e., the ventrolateral periaqueductal gray and locus coeruleus-also sent a small number of inputs to NTSLepRb neurons. In addition, anterograde tracing results demonstrated that NTSLepRb neurons sent efferent projections to 15 nuclei, including the dorsomedial hypothalamic nucleus and arcuate hypothalamic nucleus, which are involved in regulation of energy metabolism and feeding behaviors. Quantitative statistical analysis revealed that the inputs of the whole brain to NTSLepRb neurons were significantly greater than the outputs. Our study comprehensively revealed neuronal connections of NTSLepRb neurons in the whole brain and provided a neuroanatomical basis for further research on physiological and pathological functions of NTSLepRb neurons.

Abstract Bone marrow‐derived mesenchymal stem cells (BM‐MSCs) are important precursors of tumor stromal cells. Previously, we have demonstrated that miR‐155‐5p inhibition directly induced transition of BM‐MSCs into gastric cancer‐associated MSCs. Whether miR‐155‐5p is involved in the education of BM‐MSCs by gastric cancer cells has not been established. Murine BM‐MSCs (mMSCs) were isolated and grown in conditioned medium derived from gastric cancer cell line MFC (MFC‐CM). The tumor‐promoting phenotype and function of mMSCs were detected by immunofluorescence staining, quantitative reverse transcription‐polymerase chain reaction (qRT‐PCR), cell colony formation assay, transwell migration, and invasion assays. Luciferase reporter assays and western blot analyses were conducted to reveal the relationship between nuclear factor kappa‐light‐chain‐enhancer of activated B cells (NF‐κB) p65 and mmu‐miR‐155‐5p. miRNA mimics, inhibitor, and the NF‐κB inhibitor pyrrolidine dithiocarbamic acid (PDTC) were used to evaluate the role of miR‐155‐5p‐NF‐κB signaling in the education of mMSCs by MFC‐CM. We successfully established the education model of mMSCs by MFC‐CM and found that mmu‐miR‐155‐5p expression levels were reduced in mMSCs. Mimicking this deregulation by transfecting miRNA inhibitor into mMSCs produced a similar effect as that of MFC‐CM on mMSCs. NF‐κB p65 was validated as a target of mmu‐miR‐155‐5p, which also negatively regulated NF‐κB activation. Inhibition of NF‐κB activation by PDTC abolished the effect of the miRNA inhibitor on mMSCs. mmu‐miR‐155‐5p overexpression partially blocked the effect of MFC‐CM in educating mMSCs, while PDTC treatment completely eliminated MFC‐CM activity. These results indicate that miR‐155‐5p is not the sole miRNA mediating the education of BM‐MSCs by gastric cancer cells, but downstream NF‐κB signaling is indispensable for this process.
Objective To observe the effects of recombinant human erythropoietin(rHuEPO) on the hippocampal neurons of status epilepticus(SE) Sprague-Dawley(SD) rats which kindled by pentylenetetrazol(PTZ) and then explore the possible mechanism of rHuEPO through the variations of X-linked inhibitor of apoptosis protein (XIAP) post the phosphatidyl inositol 3-kinase(PI3K) inhibitors LY294002 application.Method The SE rats kindled by the PTZ were randomly divided into normal control group(normal saline, NS)、PTZ group(PTZ+NS), rHuEPO group(PTZ+rHuEPO)、LY294002 group(PTZ+LY294002+rHuEPO) and LY294002 solvent dimethyl sulfoxide(DMSO) control group(PTZ+DMSO+rHuEPO). The behavior changes and electroencephalogram(EEG)recording of rats were detected; The changes of hippocampal pathology were detected through HE staining; The expression of phosphorylated protein kinase B(PKB/p-Akt)、XIAP were detected through immunohistochemical method; The expression of hippocampal XIAPmRNA were detected through reverse transcription polymerase chain reaction (RT-PCR); The expression of Akt, p-Akt and XIAP protein in hippocampal neurons were detected through Western blot method.Results The expression of p-Akt and XIAP were down-regulated by PTZ. rHuEPO can increase the expression of p-Akt and XIAP, and then play the neuroprotective role. With the application of PI3K inhibitor LY294002, the expression p-Akt, XIAP protein and XIAPmRNA decreased than rHuEPO group in hippocampus, and decreased the protective effect of rHuEPO.Conclusion The PI3K/Akt signaling pathway is one of the pathways through that rHuEPO play neuroprotective effects and be testified from the two aspects of positive and negative. The mechanism may be rHuEPO activated the PI3K/Akt pathway, regulated the expression of XIAP and then mediated mitochondrial apoptosis pathway to play the role of antiapoptotic and promote survival effects.
