Chronic heart failure (CHF) impairs cognitive function. Xijiaqi Formula (XJQ), a traditional Chinese medicine (TCM) used clinically to treat CHF, demonstrates potential for improving cognition in CHF patients. However, its precise mechanism in treating post-CHF cognitive dysfunction remains unclear. This study systematically investigates XJQ's effects on post-CHF cognitive dysfunction and the underlying mechanisms. The components of XJQ were identified through liquid chromatography-mass spectrometry. CHF was induced in rats via ligation of the left anterior descending coronary artery, followed by six weeks of XJQ treatment. Cardiac function was evaluated through echocardiography and hemodynamic parameters, while cognitive function was assessed using Morris water maze (MWM) and open field tests (OFT). XJQ treatment enhanced both cardiac and cognitive functions in CHF rats. Network pharmacology identified 12 core active components of XJQ and indicated its effect on cognitive dysfunction involved regulating synapses, inflammation, and phosphodiesterase 4 (PDE4)-dependent cyclic adenosine monophosphate (cAMP) signaling. XJQ inhibited microglial and astrocyte activation, decreased proinflammatory cytokines, and mitigated neuronal damage. Notably, XJQ promoted synaptic repair and dendritic growth by downregulating PDE4 and upregulating cAMP, protein kinase A (PKA), cAMP-response element binding protein (CREB), brain-derived neurotrophic factor (BDNF), PSD95, and synapsin I levels. Molecular docking and Bio-layer interferometry assays confirmed direct binding of quercetin, kaempferol, isorhamnetin, and darutoside to PDE4. In conclusion, XJQ alleviates neuroinflammation and enhances synaptic plasticity to improve cognitive dysfunction in CHF rats via the PDE4/cAMP/PKA/CREB signaling pathway. These findings provide valuable insight into the heart-brain axis. Show less

Major depressive disorder (MDD) involves multifaceted pathologies including neurotransmission, neuroplasticity, inflammation, and hypothalamic-pituitary-adrenal (HPA) axis dysfunction. Growing evidence implicates zinc homeostasis imbalance in MDD, yet a systematic framework integrating it into these mechanisms is lacking. This narrative review synthesizes literature (2000-2024) to elucidate the multidimensional associations between zinc homeostasis and MDD pathology, focusing on zinc's roles in neurotransmitter regulation, BDNF signaling, inflammation, oxidative stress, and HPA axis activity. Epidemiological studies indicate an inverse correlation between serum zinc levels and MDD. Mechanistically, zinc imbalance may disrupt neural signaling via glutamate/GABA/5-HT receptors, impair neurotrophy via BDNF, exacerbate neuroinflammation and oxidative stress, and promote HPA axis hyperactivity. Zinc supplementation shows efficacy in mild-to-moderate MDD and augments conventional antidepressants, especially in treatment-resistant cases. Novel targets like GPR39 and zinc transporters, along with brain-targeted formulations, offer promising therapeutic avenues. Zinc homeostasis is critically involved in MDD's heterogeneous pathology, making it a promising target for precision treatment. However, this potential is tempered by inconsistent data and methodological limitations. Future research should prioritize: standardizing assessment methods; investigating brain region-specific zinc dynamics; developing novel targeted formulations; and exploring gene-environment interactions in zinc signaling.

Electroconvulsive therapy (ECT) stands as the most effective intervention for treatment-resistant depression; however, its interaction with dietary regulation of the gut-brain axis has not been thoroughly explored. This study aimed to elucidate the mechanistic link between ECT, gut microbiota remodeling, short-chain fatty acid (SCFA) production, and neural plasticity. In this study, mice were subjected to chronic restraint stress (6 h/d for 28 consecutive days) to establish a depression-like model. Utilizing a translational approach that incorporated behavioral assessments, multimodal neuroimaging techniques such as PET-CT and laser speckle contrast imaging, along with multiomics analyses including metagenomics, metabolomics, and transcriptomics in rodent models, we demonstrated that ECT induced significant gut microbiota remodeling, characterized by an enrichment of SCFA-producing genera like Lactobacillus and Bifidobacterium. This remodeling was associated with restored intestinal barrier integrity and elevated plasma SCFA levels. Mechanistically, these microbial metabolites activated hippocampal Wnt/β-catenin signaling pathways, enhancing synaptic plasticity restoration, while concurrent probiotic supplementation further amplified brain-derived neurotrophic factor (BDNF) expression via SCFA-dependent epigenetic mechanisms. Neuroimaging corroborated the normalization of cerebral glucose metabolism and hemodynamic function post-ECT. In conclusion, our findings unveil a novel gut-brain communication pathway by which ECT exerts its antidepressant effects, positioning SCFAs as vital mediators connecting microbial metabolic alterations to neural plasticity. This research not only redefines the role of nutritional biochemistry in neuromodulation but also suggests the potential of microbial metabolite monitoring to tailor antidepressant therapies for enhanced efficacy.

Dietary bile acids (BAs) have been shown to affect food intake in chicks; however, the underlying central mechanisms remain unclear. This study investigated the effects of taurochenodeoxycholic acid (TCDCA), sodium taurocholate (STC), chenodeoxycholic acid (CDCA), taurocholic acid (TCA), hyodeoxycholic acid (HDCA), allocholic acid (ACA), and a mixed BA (MBA; 4.6% hyodicolate, 72.6% hyodeoxycholate, and 18.3% chenodeoxycholate) on feed intake and hypothalamic mRNA expression of appetite-related neuropeptides in chicks. To determine the effects, intracerebroventricular (ICV) injections of three doses (0.25, 0.5, and 1 μg) of each BA were administered to 5-day-old layer-type chicks, and feed intake was recorded at 30, 60, and 120 minutes post-injection. Quantitative PCR was used to determine the hypothalamic mRNA expression of neuropeptide Y (NPY) and its receptors, agouti-related peptide (AgRP), pro-opiomelanocortin (POMC), and melanocortin receptors. Results showed that feed intake decreased after ICV administration of CDCA, CA, HDCA, MBA, and STC, whereas ACA and TCDCA increased intake (P < 0.05). TCDCA upregulated NPY5R, while CDCA downregulated NPY4R (P < 0.05). STC and CA increased POMC and MC4R expression and reduced AgRP (P < 0.05), whereas HDCA decreased AgRP (P < 0.05). ACA reduced MC4R expression, and MBA downregulated both NPY4R and NPY5R (P < 0.05). The result suggests that both orexigenic and anorexigenic neuropeptide genes are involved in the effects of BAs. The effect of BAs acts in a dose-dependent manner in the hypothalamus to influence feed intake. Show less

Keratoconus (KC) is a progressive disorder of corneal thinning characterized by responses in the extracellular matrix and cellular interactions. This study used bioinformatics methods to identify key genes involved in KC development and in anoikis and endoplasmic reticulum (ER) stress. KC and control datasets from the GEO database were analyzed to identify differentially expressed genes (DEGs). These were cross-referenced with anoikis and ER stress-related genes from Genecards. Functional enrichment, immune infiltration analysis, and machine learning techniques (LASSO, Random Forest) were used to identify candidate molecular signatures, which were then validated in an animal model. We identified 46 DEGs associated with anoikis and 41 DEGs related to ER stress. Functional analysis linked them to apoptosis and IL-17 signaling. Five key molecular signatures were identified: CDKN1A, MCL1, PTGS2, PTHLH, and ANGPTL4. The expression of ANGPTL4, CDKN1A, and MCL1 was consistent in the animal model. These genes are associated with inflammatory and oxidative stress responses. Twelve potential therapeutic drugs were predicted. This study identifies five candidate molecular signatures for KC related to anoikis and ER stress, offering insights into KC pathogenesis and potential targeted therapies. Show less

With global climate warming increasingly threatening aquatic ecosystems, prolonged exposure to high temperatures has become a major environmental stressor for both wild and cultured fish. However, the long-term effects of chronic heat stress on blood physiology and hematopoietic processes remain poorly understood. To assess the long-term impacts of chronic heat stress on hematopoiesis in largemouth bass (Micropterus salmoides), we conducted a 180-day acclimation experiment at 34 °C. Hematological analyses showed significant reductions in red blood cell counts and hemoglobin concentrations, indicating impaired oxygen transport capacity. Blood cell morphology was altered, with erythrocytes exhibiting a lower major-to-minor axis ratio and leukocytes (lymphocytes and granulocytes) showing increased volumes. Histological and ultrastructural observations of the head kidney revealed tissue loosening, hemosiderin deposition, mitochondrial damage, and elevated apoptosis. Furthermore, transcriptomic analysis combined with GO and KEGG enrichment revealed that pathways involved in vascular development, stress response, and fatty acid metabolism were significantly activated under heat stress. Notably, key genes associated with angiogenesis, lipid metabolism, stimuli response, apoptosis and immunity, including mmp9, angptl4, abca1 and stab2, were markedly upregulated, suggesting their crucial roles in vascular remodeling and thermotolerance. Together, these results provide the first integrative cellular and molecular characterization of hematopoietic responses to prolonged high temperature in M. salmoides. The findings enhance understanding of fish physiological plasticity under environmental stress and have implications for aquaculture management and the development of heat-resilient strains.

Angiopoietin-like protein 8 (ANGPTL8), a member of the angiopoietin-like protein (ANGPTL) family, is a physiological inhibitor of lipoprotein lipase (LPL), and plays a critical role in lipoprotein and triglyceride metabolism in response to nutritional cues. ANGPTL8 is implicated in a wide range of systemic and cellular processes and is closely associated with metabolic and cardiovascular diseases (CVD). Circulating ANGPTL8 is primarily secreted by the liver, with adipose tissue as a secondary source. Its expression is regulated by multiple transcription factors and microRNAs, and is responsive to fasting/refeeding states, hormonal signals, and stress conditions. In lipid metabolism, ANGPTL8 forms complexes with ANGPTL3 and ANGPTL4 to modulate LPL activity under fasting and feeding conditions. In glucose metabolism, ANGPTL8 plays a complex role. While some studies suggest it may improve glucose tolerance and insulin resistance, others indicate it could exacerbate glucose metabolism disorders and diabetes, or have no effect. Cardiovascular diseases are intricately linked to metabolic disorders and diseases. Increasing evidence also links ANGPTL8 to various cardiovascular pathologies, including atherosclerosis, hypertension, cardiomyopathy, cardiac hypertrophy, aortic aneurysm, and dissection. Given the strong interplay between metabolic dysregulation and CVDs, elucidating the role of ANGPTL8 in these processes is of significant interest. This review provides a balanced assessment of ANGPTL8's roles in key pathophysiological processes, highlighting its established functions in metabolism alongside its emerging involvement in CVDs. Understanding the diverse functions of ANGPTL8 in various tissues and metabolic states will lead to new opportunities for therapeutic intervention in cardiometabolic disorders. Show less

The genetic and phenotypic spectrum of homozygous familial hypercholesterolemia (HoFH) in Han Chinese populations remains insufficiently defined. To delineate the nationwide genetic and clinical features of HoFH in Taiwan, including true HoFH, double heterozygous FH (HeFH), and compound HeFH. Patients with clinically diagnosed probable or definite FH enrolled in the Taiwan FH Registry who underwent genetic testing between 2006 and 2025 were analyzed. A comprehensive workflow integrating microarray assay, mass spectrometry, targeted next-generation sequencing, and multiplex ligation-dependent probe amplification was implemented. Variants were classified using American College of Medical Genetics and Genomics guidelines. Of 1479 screened individuals, 63 were genetically confirmed to have HoFH (mean age, 32.8 ± 22.7 years), including 28.6% with atherosclerotic vascular disease. The cohort comprised 14 true HoFH (including homozygous APOB variants), 6 double HeFH, and 43 compound HeFH. The highest documented low-density lipoprotein cholesterol (LDL-C) levels were 357.3 ± 123.5 mg/dL in true HoFH, 347.3 ± 39.2 mg/dL in double HeFH, and 443.5 ± 170.9 mg/dL in compound HeFH.

This study aims to investigate the underlying pathophysiological relationship between obesity and osteoporosis (OP) in obese individuals, involving lipid metabolism, inflammation, and bone mineral density (BMD). Data from 318 patients diagnosed OP at our hospital between January 2023 to December 2025 were collected and analyzed. The basic information of the patient included gender, age, BMI, drinking and smoking history, diabetes, hypertension and bone mineral density (T-scores) were recorded. Baseline peripheral blood was employed to calculate lipid markers and inflammatory cytokines. Linear regression and mediation analyses were employed to assess the relevance and differences. Increased level of blood lipids and inflammatory cytokines were associated with increased risks of OP in obesity. Compared to normal-weight individuals, obese subjects exhibited significantly lower BMD. Dysregulated lipids (TC, TG, HDL-C, ApoB) negatively correlated with BMD in obesity. Pro-inflammatory cytokines (TNF-α, IL-1β, IL-6, IL-8) inversely associated with BMD, while anti-inflammatory IL-10 showed positive association. Hyperlipidemic obese individuals had elevated inflammatory cytokines (TNF-α, IL-1β) and exacerbated BMD loss. Mediation analysis revealed TNF-α mediated 41.91% and IL-6 mediated 33.20% of the TC-BMD association; TNF-α and IL-6 mediated 28.76% and 37.38% of HDL-C-BMD effects, respectively. Obesity-associated dyslipidemia drives BMD loss partly through inflammation-mediated pathways. Key inflammatory cytokines significantly mediate lipid metabolism’s impact on bone health. Targeting lipid-inflammatory crosstalk may optimize OP management in obese populations. Show less

The effects of lipid traits on colorectal cancer (CRC) risk and the extent to which obesity may modify these effects remain unclear. To examine the associations between lipid traits and CRC risk using an observational study and Mendelian randomization (MR) analyses, and the role of weight status in the potential associations. In the Guangzhou Biobank Cohort Study (GBCS), lipid profiles were measured during 2003-2008, and CRC events were identified through record linkage with the cancer registry. MR analyses assessed the causal effects of lipid traits on CRC using a genome-wide association study meta-analysis of 185,616 Europeans. Among 28,576 GBCS participants followed until 2020, 599 CRC events occurred. Participants in the highest quartile of apolipoprotein B (apoB) had a higher CRC risk (hazard ratio [HR] 1.43, 95% CI 1.02-2.01). This association remained in those with overweight/obesity (HR 2.21, 95% CI 1.28-3.83). MR analyses supported a detrimental effect of apoB on CRC (odds ratio 1.12 per 1 SD, 95% CI 1.02-1.22). MR analyses also showed positive associations for total cholesterol and the apoB/apolipoprotein A-I ratio, which were not significant in the observational study. Higher apoB levels were associated with an increased CRC risk in both observational and MR analyses, suggesting a potential role of apoB in CRC prevention, especially among participants with overweight/obesity. However, the limitations of single-time lipid measurements and the use of different ancestries across study designs indicate the need for further research to confirm the robustness and generalizability of the findings.

This study developed and validated a continuous metabolic syndrome (MetS) risk score (msRS) for adolescents and evaluated its clinical utility in identifying multiple clinical cardiovascular markers (CCMs) using dual adolescent populations. Adolescents aged 12‒18 from two stratified random samples were used: the nationwide Nutrition and Health Survey in Taiwan (NAHSIT, n = 1920) for development and the Adiposity‒Cardiovascular Disease Axis study in Southern Taiwan (adiCards, n = 3295) for validation. Four sex-and-age-specific msRS were developed through confirmatory factor analysis (CFA) utilizing five MetS components-waist circumference, high-density lipoprotein cholesterol, triglycerides, fasting glucose, and mean arterial pressure. Their discriminatory ability for clinical outcomes was validated using the area under receiver operating characteristic (AU-ROC) curve. The msRS demonstrated exceptional capability in detecting MetS in NAHSIT and adiCards cohorts (AU-ROCs: 0.954‒0.969). Adjusted for covariates, msRS explained higher variability in body-fat percentage, apolipoproteins B/A1, and homeostatic model assessment of insulin resistance (HOMA-IR) than binary MetS and abnormal components count (partial R The CFA-derived sex-and-age-adjusted msRS scheme provides an improving measure to assess and manage adolescent cardiometabolic health. Adolescent MetS components share a latent metabolic construct. A scoring system through confirmatory factor analysis captures sex-and-age specific metabolic heterogeneity. Continuous risk score accurately discriminates pediatric MetS. MetS risk score effectively detects pediatric cardiovascular risk.

BuYang HuanWu Decoction (BYHW), a classical herbal formula first documented in Yilin Gaicuo (1830), is officially listed in the Chinese Pharmacopoeia for the treatment of stroke and sequelae attributed to "qi deficiency and blood stasis." Vertebral artery stenosis (VAS) is a leading cause of posterior circulation ischemic stroke-a condition for which BYHW has been traditionally prescribed. However, the molecular mechanism underlying its therapeutic effects against VAS remains poorly understood. This study aimed to systematically predict the therapeutic targets of BYHW against VAS using network pharmacology and to experimentally validate its core mechanism of action, with a focus on the AGE-RAGE/NF-κB signaling axis. Potential targets of BYHW and VAS-related genes were retrieved from TCMSP and DisGeNET databases for network construction and enrichment analysis. Key predictions were validated in vitro using ox-LDL/AGEs-stimulated human umbilical vein endothelial cells (HUVECs) and RAW 264.7 macrophages, and in vivo using ApoE Network analysis identified 62 common targets and six core hubs (IL-6, IL-10, FOS, MAPK1, AKT1, and CTNNB1), with the AGE-RAGE signaling pathway being the most significantly enriched. In vitro, BYHWE inhibited ox-LDL/AGEs-induced endothelial inflammation, oxidative stress, and macrophage foam cell formation by suppressing the AGE-RAGE/NF-κB axis. In vivo, BYHWE administration (2 g/kg/day for 4 weeks) significantly attenuated atherosclerotic plaque burden by 34.7% and reduced macrophage infiltration in ApoE This study provides the first evidence that BYHW alleviates VAS through multi-target modulation of the AGE-RAGE/NF-κB pathway, thereby protecting endothelial function and stabilizing plaques. These findings offer a mechanistic explanation for its traditional use in stroke-related disorders and support its therapeutic potential for atherosclerotic vertebral artery stenosis. Show less

The apolipoprotein E ε4 (APOE ε4), a well-established genetic risk factor for Alzheimer's disease (AD), is deeply involved in amyloid-β (Aβ) and tau pathology. Blood-based biomarkers (BBMs), including Aβ42/40, phosphorylated tau (p-tau181), glial fibrillary acidic protein (GFAP) and neurofilament light (NfL), offer accessible proxies of AD pathology. Reactive astrocytes, indicated by elevated GFAP, are increasingly recognized as key players in AD progression. However, how astrocyte reactivity interacts with APOE genotype to shape BBMs and Aβ deposition remains unclear. We included 283 participants across the cognitive spectrum including cognitively unimpaired (CU), mild cognitive impairment (MCI), and all-cause dementia (ACD) from Guangzhou health aging and dementia cohort. Primary outcome measures were plasma biomarkers (Aβ42/40 ratio, p-tau181, GFAP, and NfL) and amyloid PET standardized uptake value ratio (SUVR). Participants were stratified by APOE ε4 carrier status and astrocyte activation. Group comparisons, correlation analyses, and sensitivity analyses were performed. Stage-dependent APOE effects were observed: while modulating Aβ42/40 ratios in both CU and MCI, APOE influenced p-Tau181 only in MCI, exclusively under Ast-. SUVR was significantly higher in APOE ε4 + group at MCI stage, particularly in Ast- cases. Intriguingly, p-Tau/Aβ42 showed strong SUVR correlations across all subgroups except APOE ε4- Ast- group. Our findings indicate that astrocyte reactivity is associated with differences in how APOE ε4 relates to both peripheral BBMs and central Aβ deposition, supporting an interplay between genetic risk and neuroinflammatory states in AD pathogenesis.

Atherosclerotic plaque rupture, driven by a vicious pathological cycle between endothelial-to-mesenchymal transition (EndMT) and chronic inflammation, represents a major therapeutic challenge in cardiovascular disease. Current clinical strategies, including statins and antiplatelet agents, fail to disrupt the EndMT-inflammation axis, while conventional TGF-β pathway inhibitors-critical for EndMT regulation-exhibit narrow therapeutic windows and systemic toxicity owing to the pleiotropic nature of TGF-β signaling. Here, we reported VRBPC, a VCAM-1-targeting, reactive oxygen species (ROS)-responsive baicalin-peptide conjugate that undergoes in situ self-assembly within atherosclerotic plaques to form a "molecular latch" that breaks the EndMT-inflammation loop. Upon VCAM-1-mediated endocytosis into activated endothelial cells, VRBPC responds to elevated ROS levels in the plaque microenvironment, triggering localized self-assembly that enhances baicalin retention and promotes its competitive binding to HSP90-a critical chaperone for TGF-β receptor stabilization. This mechanism inhibits Smad2/3 phosphorylation, reverses EndMT, and simultaneously suppresses inflammatory responses in macrophages. In vitro, VRBPC effectively restored endothelial phenotype, reduced aberrant migration, and diminished foam cell formation alongside pro-inflammatory cytokine secretion. In ApoE Show less

Atherosclerosis is respectively correlated with interleukin-6/interleukin-6 receptor (IL6/IL6R) mediated inflammation signaling and macrophages ferroptosis. Nonetheless, the underlying mechanism of IL6/IL6R signaling mediated macrophages ferroptosis in atherosclerosis remains unknown. This study aims to investigate whether IL6/IL6R signaling mediated macrophages ferroptosis through mitochondrial fragmentation and mitophagy impairment. Two human atherosclerotic transcriptomic datasets were used to conduct bioinformatic analysis. In vitro, counting kit-8 (CCK-8) assays, flow cytometry, immunofluorescence staining, malondialdehyde (MDA) and glutathione (GSH) assay kits were employed to evaluate reactive oxygen species (ROS) levels and macrophages ferroptosis. Transmission electron microscopy (TEM), laser confocal microscope and seahorse experiments were used to evaluate changes of mitochondrial morphology and mitochondrial function. Western blotting (WB) was used to quantify key markers of mitophagy and ferroptosis. In vivo, histological stainings and WB were used to determine the effects of IL6R deficiency on atherosclerosis, mitophagy and ferroptosis. Integrated bioinformatic analysis revealed that the IL6 expression could stratify early and advanced plaques. IL6 induced macrophages ferroptosis by increasing ROS and MDA levels, depleting GSH level, promoting lipid peroxidation and suppressing glutathione peroxidase 4 (GPX4) expression. Dynamin-related protein 1 (Drp1) mediated excessive mitochondrial fragmentation in IL6-induced macrophages, resulting in more shortened mitochondria, impaired oxidative phosphorylation (OXPHOS) and ROS accumulation. Activation of mitophagy, the process of mitochondrial fragmentation clearance, could increase GPX4 expression and attenuate the lipid peroxidation level in IL6 induced macrophages. Aggravation of ferroptosis further compromised mitophagy-related proteins expression.

Based on the TCM theory of "phlegm-stasis intermingling", this study aims to investigate the mechanism of Danzha Tongmai Pills(DZTMW) in treating atherosclerosis(AS), focusing on elucidating its in vivo active components, metabolic regulatory effects in serum, hepatoprotective effects, and anti-inflammatory efficacy. An AS model was established in apolipoprotein E knockout(ApoE~(-/-)) mice, which were divided into a normal group, an model group, low/medium/high-dose DZTMW groups, and an atorvastatin positive control group. The normal group was fed a standard diet, while the other groups were fed a high-fat diet to induce AS lesions. During the intervention phase, the groups were administered corresponding drugs or an equal volume of solvent by gavage. A series of tests were conducted after continuous intervention. Ultra-performance liquid chromatography-quadrupole-time-of-flight mass spectrometry(UPLC-Q-TOF-MS) was used to identify the blood-entering components of DZTMW, and liquid chromatography-high-resolution mass spectrometry(LC-HRMS) was employed for non-targeted serum metabolomics analysis. Pearson correlation analysis was used to analyze the correlation between blood-entering components and differential metabolites. Levels of serum lipid [total cholesterol(TC), triglycerides(TG), low-density lipoprotein cholesterol(LDL-C), high-density lipoprotein cholesterol(HDL-C), and free fatty acids(FFA)] and liver function markers [alanine aminotransferase(ALT) and aspartate aminotransferase(AST)] were measured. Liver histopathology and lipid deposition were assessed by HE and oil red O staining, and serum levels of inflammatory factors [lipoprotein-associated phospholipase A2(LP-PLA2), high-sensitivity C-reactive protein(hs-CRP), interleukin-6(IL-6), tumor necrosis factor-alpha(TNF-α), and interleukin-1 beta(IL-1β)] were measured by enzyme-linked immunosorbent assay(ELISA). The results showed that 23 blood-entering components were identified from DZTMW, including three prototype compounds, 20 metabolites, and 142 differential metabolites of serum. Core blood-entering components such as hydroxyl asiatic acid M1 and neocryptotanshinone metabolite were highly/extremely correlated with differential metabolites like 5-hydroxytryptamine, lysophosphatidylcholine(P-18:1/0:0) and sphingomyelin(d18:1/15:0). DZTMW administration at various doses significantly reduced the serum levels of TC, TG, LDL-C, and FFA(P<0.01), increased the HDL-C level(P<0.01), decreased ALT and AST activities(P<0.05, P<0.01), alleviated hepatocyte steatosis and lipid droplet deposition, and down-regulated the expression of inflammatory factors in a dose-dependent manner(P<0.01). The effects of the high-dose DZTMW group were comparable to those of the atorvastatin group. In summary, DZTMW can effectively inhibit the progression of AS in ApoE~(-/-) mice. Its mechanism may involve the regulation of hepatic lipid metabolism by its in vivo active components to ameliorate the "phlegm-turbidity" pathology and reduce liver injury, and the inhibition of systemic inflammation to alleviate the "blood stasis" process. The study can provide a modern biological basis for the theory of "phlegm-stasis intermingling". Show less

The We employed a multi-omics approach, combining snRNA-seq and locus-specific epigenetic analysis, alongside microglia-specific gene manipulation in ApoE-targeted replacement (TR) mice. Primary microglia were challenged with cholesterol to simulate lipid overload conditions. In mid-life ApoE4-TR mice, microglia within the dentate gyrus developed pronounced lipid droplet accumulation, concurrent with impaired Aβ clearance and a pro-inflammatory shift. snRNA-seq unveiled a unique microglial cluster in ApoE4 mice, enriched for lipid-metabolism genes and marked by the pronounced downregulation of the hub gene Asxl1. Mechanistically, ApoE4 attenuated the Asxl1–LXRα interaction, leading to reduced H3K4me3 occupancy at promoters of lipid-efflux genes such as Abca1. Crucially, CRISPR-mediated, microglia-specific overexpression of Asxl1 restored H3K4me3 levels, normalized cholesterol efflux, and rescued Aβ phagocytic deficits in vivo. Our findings define an epigenetic pathway whereby ApoE4 drives microglial dysfunction via the Asxl1–LXRα–H3K4me3 axis, fostering the LDAM phenotype. Enhancing Asxl1 function presents a promising therapeutic avenue for countering ApoE4-mediated pathogenesis in AD.

Atherosclerosis (AS) is a chronic inflammatory disease that constitutes the primary pathological basis of cardiovascular disorders. Although the natural isoflavone C-glycoside puerarin (PU) has demonstrated promising anti-atherosclerotic effects, its underlying molecular mechanisms remain incompletely elucidated. In this study, we aimed to systematically characterize the pharmacological actions and mechanistic basis of PU in AS by integrating network pharmacology analyses with experimental validation. Potential targets of PU were identified by integrating network pharmacology databases and intersecting them with AS-related genes. Protein-protein interaction analysis, functional enrichment, and machine-learning-based screening were subsequently performed to identify key regulatory targets. Molecular docking and molecular dynamics simulations were then conducted to evaluate the feasibility and stability of PU-target interactions. In addition, single-cell transcriptomic and immune infiltration analyses were used to determine the cellular localization and inflammatory relevance of the core targets. Finally, a high-fat diet (HFD)-induced ApoE This integrative analysis identified 56 potential PU-AS-related targets, among which TNF, NFKBIA, STAT3, SRC, and PTGS2 emerged as central hub genes. Notably, TNF was consistently highlighted as a key regulatory target across differential expression analysis, molecular docking, and molecular dynamics simulations. Single-cell transcriptomic and immune infiltration analyses further revealed that TNF was predominantly expressed in macrophages and related immune cell subsets. Experimental validation demonstrated that PU treatment significantly attenuated inflammatory responses, reduced aortic plaque burden, enhanced plaque stability, and suppressed macrophage infiltration in HFD-induced ApoE PU ameliorates atherogenesis by suppressing TNF-NF-κB-mediated inflammatory responses. These findings identify the TNF-NF-κB axis as a key mechanistic pathway underlying the anti-atherosclerotic effects of PU and support its potential as a natural product-based therapeutic strategy for cardiovascular disease.

The identification of plasma biomarkers for the diagnosis of Alzheimer's disease (AD) has been a longstanding research priority; however, few plasma biomarkers have yet been implemented in routine clinical practice. This study enrolled 141 participants, including 71 patients with AD, 44 individuals with mild cognitive impairment, and 28 cognitively healthy controls (HC). A total of 16 plasma inflammatory proteins were quantified using multiplex liquid-chip assays, and APOE genotyping was performed. The diagnostic utility of plasma proteins was assessed using the least absolute shrinkage and selection operator (LASSO) with nested cross-validation. Patients with AD exhibited marked alterations in plasma inflammatory profiles, with elevated levels of IFN-γ, IL-33, and IL-18, and reduced levels of IL-7 and CCL11. Integrating inflammatory markers with clinical variables and APOE genotype substantially improved discrimination between AD and HC, increasing the area under the ROC curve from 0.863 to 0.953. Among all biomarkers, IFN-γ emerged as the most informative predictor and was significantly elevated in AD patients carrying the APOE ϵ4 allele. Analyses of single-nucleus RNA sequencing data further revealed pronounced enrichment of IFN-γ signaling in APOE4/4 AD-associated lipid droplet-accumulating microglia (LDAM), defined by high ACSL1 expression. Notably, IFN-γ stimulation enhanced ACSL1 expression in ApoE4-overexpressing HMC3 microglial cells. These findings provide a new perspective on the involvement of plasma inflammatory markers for AD diagnosis, and suggest a novel link between IFN-γ and APOE ϵ4-associated AD risk through modulating the ACSL1-driven pathogenic LDAM phenotype.

Atherosclerosis is characterized by chronic vascular inflammation involving endothelial dysfunction and macrophage-mediated inflammatory responses. However, the molecular mechanisms linking these processes remain incompletely understood. This study investigates the role of interleukin-32γ (IL-32γ) in mediating endothelial-macrophage interactions during atherosclerosis progression. IL-32 isoform expression was analyzed in peripheral blood samples from atherosclerosis patients and healthy controls. Human endothelial cells were treated with oxidized low-density lipoprotein (Ox-LDL) with or without NF-κB inhibitor. Endothelial-macrophage interactions were studied using Transwell co-culture systems with THP-1-derived macrophages. Macrophage polarization was assessed by flow cytometry, qRT-PCR, and ELISA. The direct effects of IL-32γ were evaluated using recombinant protein with or without p38 MAPK inhibitor. In vivo studies employed ApoE-/- mice fed a Western diet and administered with IL-32γ alone or with p38 inhibitor. IL-32γ was significantly upregulated in atherosclerosis patients. Ox-LDL induced IL-32γ expression in endothelial cells through NF-κB activation, concurrent with endothelial dysfunction. Ox-LDL-treated endothelial cells promoted M1 macrophage polarization and migration, effects attenuated by either NF-κB inhibition or IL-32γ neutralization. Treatment with recombinant IL-32γ induced M1 polarization through p38 MAPK signaling. In ApoE-/- mouse model, IL-32γ administration accelerated atherosclerotic plaque formation and macrophage infiltration, while p38 inhibition reversed these effects. IL-32γ serves as a crucial mediator between Ox-LDL-induced endothelial dysfunction and macrophage-mediated inflammatory responses in atherosclerosis. Endothelial-derived IL-32γ promotes M1 macrophage polarization through p38 MAPK signaling, accelerating disease progression. These findings identify IL-32γ as a potential therapeutic target for atherosclerotic cardiovascular disease. Show less
