Depression and anxiety disorders are highly comorbid, yet their complex pathogenesis often limits the efficacy of monotherapy. Growing evidence implicates neuroinflammation in their pathogenesis. Co-drugs that linked two active molecules into a single compound and released the drugs after administration, which offering improved efficacy and tolerability than individual drug mixtures or monotherapy. In this work, five new co-drugs ODV-NSAIDs were synthesized from O-desmethylvenlafaxine (ODV) with non-steroidal anti-inflammatory drugs (NSAIDs) to achieve synergistic antidepression and anxiolytic effects. In vitro stability studies exhibited that these co-drugs can be metabolized into two single drugs within 60 min in simulated intestinal fluid. In both acute and chronic LPS-induced models, co-drug ODV-NAP significantly ameliorated depressive-like behaviors, evidenced by increased sucrose preference, reduced immobility in the tail suspension test (TST) and forced swim test (FST), and enhanced locomotion in the open field test (OFT). Furthermore, ODV-NAP decreased brain levels of pro-inflammatory cytokines (TNF-α, IL-1β, IL-6) and malondialdehyde (MDA), while elevating serotonin (5-HT), norepinephrine (NE), and superoxide dismutase (SOD) activity. Nissl staining confirmed ODV-NAP significantly attenuated hippocampal neuronal damage. Moreover, western blotting revealed ODV-NAP inhibited the TLR4/NF-κB signaling pathway and upregulated BDNF and p-TrkB protein expression. ODV-NAP also inhibited LPS-induced p65 nuclear translocation in BV-2 microglia in vitro, and caused no toxicity in histology. Thus, co-drug ODV-NAP represented a promising novel candidate for treating depression and anxiety. Show less

Precise identification of vulnerable plaque (VAP) is essential for the prevention of acute cardiovascular diseases, yet current molecular probes are hampered by poor VAP lesion penetration and high background. Here, the innate tropism of circulating inflammatory monocytes for VAP, and their differentiation-driven expression of legumain (Lgmn) in response to the VAP microenvironment is exploited. A monocyte differentiation-activated fluorescent (MDAF) probe is conceived that hitchhikes monocytes to precisely migrate to VAP and is activated by Lgmn during monocyte differentiation. This activation triggers in situ self-assembly, resulting in spatiotemporally controlled aggregation-induced emission (AIE) fluorescence signals, and turning the monocyte itself into an on-site "scout" that reports plaque instability.

To evaluate the preventive effect of dipeptidyl peptidase-4 inhibitors (DPP-4i) on post-stroke cognitive impairment (PSCI) in patients with type 2 diabetes mellitus (T2DM) and concurrent acute ischemic stroke (AIS). A retrospective cohort study was conducted on 236 patients with T2DM+AIS recruited from April 2021 to October 2024. Patients were grouped based on DPP-4i use: an observation group (107 cases) with DPP-4i therapy and a control group (129 cases) without. Patients' baseline demographics, clinical features, laboratory indices, and follow-up data were extracted from the electronic medical record system. The primary outcome measure was the incidence of PSCI, defined as a Montreal Cognitive Assessment Scale (MoCA) score <26 at six months after AIS. Secondary outcomes included inflammatory cytokines, oxidative stress markers, neuroprotective factors (BDNF), glycemic metabolism indicators, and life quality [Barthel Index (BI), Functional Independence Measure (FIM), and Instrumental Activities of Daily Living (IADL)]. At 6 months after AIS, the incidence of PSCI was significantly lower in the observation group than in the control group (P<0.05). Furthermore, inflammatory and oxidative stress marker levels were decreased whereas BDNF level was significantly elevated in the observation group compared to the control group (all P<0.05). According to the quality-of-life assessment, patients receiving DPP-4i had higher BI, FIM, and IADL scores (P<0.05), along with a lower all-cause readmission rate (P<0.05). Subgroup analysis indicated that different DPP-4i types (e.g., sitagliptin, saxagliptin) had consistent cognitive protective effects (P>0.05). DPP-4i can lower PSCI risk in T2DM+AIS patients. Its mechanism involves multi-dimensional effects like anti-inflammation, anti-oxidation, insulin sensitivity enhancement, and neuroprotection. Show less

Silica exposure precipitates irreversible lung injury; however, its long-term neurological sequelae—and the microglial mechanisms underlying these effects—remain poorly understood. Here, we demonstrate that inhaled crystalline silica induces persistent hippocampal inflammation, anxiety- and depression-like behaviors, and neuronal loss in mice. Bulk RNA sequencing, immunophenotyping, and pharmacological depletion studies revealed that microglia are the primary source of complement C1q in silica-exposed brains. Mechanistically, silica-induced lipocalin-2 (LCN2) engages the melanocortin-4 receptor (MC4R) on microglia, activating a cAMP/PKA/NF-κB cascade that transcriptionally upregulates C1q. Pharmacological blockade of MC4R (using PF) abolished C1q overproduction, normalized brain-derived neurotrophic factor levels, and restored both synaptic integrity and behavioral performance. Our findings establish the LCN2–MC4R–C1q axis as a critical microglial pathway in silica-related neurotoxicity and identify MC4R antagonism as a promising, readily translatable intervention for occupational neuroinflammation.

Fear of progression (FoP) is a prevalent psychological issue among stroke patients. Previous studies failing to distinguish characteristics of patient groups with varying FoP levels. Latent profile analysis (LPA) classifies individuals into distinct subgroups via continuous FoP indicators, boosting classification accuracy by accounting for variable uncertainty. Given FoP's heterogeneity, investigating FoP profiles and their influencing factors in stroke patients is clinically significant for personalized psychological care and improved patient quality of life. A total of 366 stroke patients were selected as study subjects through convenience sampling, and a cross-sectional survey was conducted. FoP was assessed using the Fear of Progression Questionnaire-Short Form (FoP-Q-SF, 2 dimensions, 12 items). Independent variables included demographic characteristics, clinical indicators, the Recurrence Risk Perception Scale for Stroke patients (RRPSS), and the Medical Coping Modes Questionnaire (MCMQ). LPA was performed on the FoP-Q-SF items to identify subgroups. The R3STEP method was used to analyze influencing factors of subgroup membership, and the BCH method was applied to compare differences in distal outcomes across subgroups. Statistical significance was set at The study sample had a mean age of 63.93 ± 10.58 years, with 70.5% males and 65.0% first-ever stroke patients. Two latent profiles were identified: Low-FoP Adaptive Type (C1, 48.6%) and High-FoP Sustained Type (C2, 51.4%). The R3STEP showed that age 18-59 years (OR = 0.476, 95%CI = 0.245-0.924, This study revealed significant heterogeneity in FoP among stroke patients. Age, hypertension comorbidity, excessive recurrence risk perception, MCMQ-confrontation, and MCMQ-avoidance were associated with high FoP. Healthcare providers should prioritize identifying high-risk individuals and develop tailored interventions to reduce FoP and improve rehabilitation outcomes. Show less

Lecanemab has been approved for the treatment of mild cognitive impairment due to Alzheimer's disease (AD) and mild AD dementia based on the efficacy in slowing cognitive decline and preliminary safety data from the phase Ⅲ Clarity AD trial. However, this trial excluded patients with high risk of cerebral hemorrhage, such as individuals with intracranial aneurysms or > 4 microhemorrhages. A 70-year-old male with mild AD, intracranial aneurysm, microhemorrhages, and APOE ε3/ε4 genotype received lecanemab after multidisciplinary evaluation and informed consent. Over six months of intensive monitoring, cognitive function stabilized with no deterioration, daily activities were preserved, microhemorrhages remained stable (with one new small lesion noted at 3 months), and no aneurysm rupture or severe adverse events (including amyloid-related imaging abnormalities) occurred. This case suggests that, despite hemorrhage risks, lecanemab may have a manageable risk-benefit profile in selected real-world AD patients under intensive monitoring and multidisciplinary care, with its application beyond clinical trial criteria requiring more nuanced and individualized consideration.

Nasopharyngeal carcinoma (NPC) is a complicated pathological cancer, which has a close association with pyroptosis and abnormal alternative splicing (AS). However, the molecular changes and functions of AS-mediated pyroptosis in cisplatin-resistant NPC cells remain poorly understood. The expression patterns of different splicing isomers of dual-specificity phosphatase 6 (DUSP6) were evaluated by semi-quantitative PCR. The effects of DUSP6 knockdown on cisplatin sensitivity and pyroptosis in NPC were examined by CCK-8 assay, immunofluorescence and ELISA. The occurrence mechanism of DUSP6 AS was explored by RNA pull down, mass spectrometry and MeRIP-PCR. DUSP6 underwent AS, among which the intron retention isoform DUSp6-IR1 increased in expression dependent on the dose and time of cisplatin. Knockdown of DUSP6-IR1 significantly suppressed viability and cisplatin resistance and promoted apoptosis of C666-1 cells upon cisplatin treatment. In vivo, sh-DUSP6-IR1 reduced the weight and volume of tumors. While DUSP6-IR1 knockdown in C666-1 cells enhanced pyroptosis (evidenced by elevated LDH release, Gasdermin D (GSDMD)/NOD-like receptor thermal protein domain associated protein 3 (NLRP3) expression, and IL-18/IL-1β levels, along with reduced cell viability), these effects were reversed by a pyroptosis inhibitor. The m6A reader protein insulin-like growth factor 2 mRNA-binding protein 3 (IGF2BP3) enhanced the splicing generation of the DUSP6-IR1 isoform through its KH3-4 domains, thereby suppressing pyroptosis in NPC cells and ultimately conferring cisplatin resistance. These findings revealed a promising novel direction to investigate cisplatin resistance and suggested potential therapeutic target for overcoming chemotherapy resistance in NPC.

Validate the clinical utility of exosome cargo (miRNAs/proteins) and NLRP3/BDNF as key regulatory molecules for acupuncture-mediated spinal cord injury (SCI) recovery. From the establishment of the database to May 2025, a literature search was conducted on PubMed, and Embase, using keywords ["exosome cargo" or "exosome"], ["acupuncture" or "acupuncture and moxibustion" or "electroacupuncture" or "EA"], ["spinal cord injury" or "SCI"], ["immune regulation"], ["inflammatory reaction"], ["neuroregeneration" or "nerve"]. Including peer-reviewed studies on human/animal models, articles that do not meet the requirements are excluded. Preclinically, MSC-exosomal miR-145-5p suppressed TLR4/NF-κB signaling, reducing spinal IL-1β by 47% in SD rats. Schwann cell-exosomal MFG-E8 activated SOCS3/STAT3, increasing M2 macrophage CD206 by 63% and raising rat BBB scores by 3.8 points; Treg-exosomal miR-2861 upregulated tight junction proteins (occludin/ZO-1) to repair the blood-spinal cord barrier. Acupuncture (EA at GV14/GV4) upregulated spinal BDNF by 72% and NGF by 58% via Wnt/β-catenin, while EA at GV6/GV9 downregulated NLRP3 by 42-58% and TNF-α by 35-47%. Clinically, EA at EX-B2 increased ASIA scores by 3.2±1.1 points (Guo et al). Besides, 5x/week EA improved ASIA vs 3x/week (+6.4 points). EA+exercise reduced MAS by 1.6-2.9 points, with outcomes correlated to peripheral NLRP3 reduction, BDNF elevation, and MBI/WISCIII increases. Exosome cargo (miR-145-5p/MFG-E8) and NLRP3/BDNF are key regulatory molecules underlying acupuncture-mediated SCI recovery. However, limitations (small RCT samples, heterogeneous acupuncture protocols, unstandardized exosome isolation) hinder translation. Future work should focus on standardized biomarker detection, exosome engineering, and large-scale clinical trials. Show less

Prednisone is used clinically during pregnancy. This study investigates whether prenatal prednisone exposure (PPE) affects susceptibility to high-fat diet (HFD)-induced metabolic dysfunction-associated fatty liver disease (MAFLD) in adult offspring and explores underlying mechanisms. Pregnant Kunming mice were administered prednisone (0.25 or 1 mg/kg; PPE-L or PPE-H) or vehicle control (5% carboxymethyl cellulose; Ctrl) by daily gavage from gestational days 0-18. Offspring were assessed metabolically, histologically, and via RNA-Seq. Primary hepatocytes were treated with fatty acids with or without the epigenetic inhibitors to evaluate Nr1h3 expression and lipid deposition. Offspring body weight was similar in PPE-L vs Ctrl, but was reduced in PPE-H group followed by delayed growth. After 6-week HFD feeding, PPE-L offspring showed mild metabolic issues, while PPE-H males exhibited significant glucose/lipid disorders and hepatic steatosis compared to controls. RNA-Seq showed upregulation of hepatic lipid pathways in the PPE-H male offspring when challenged by HFD. The liver X receptor alpha (LXRα)-sterol regulatory element-binding protein 1 (SREBP1) signaling pathway and the expression of genes involved in de novo fatty acid synthesis were increased in PPE-H offspring under HFD. A485 significantly downregulated the expression of Nr1h3 in primary hepatocytes from male PPE-H offspring and alleviated lipid deposition in these hepatocytes treated with fatty acids. The H3K27ac level in the Nr1h3 promoter in the PPE-H offspring's liver was significantly upregulated. PPE-L impairs offspring glucose/lipid homeostasis, whereas PPE-H increase MAFLD risk of the offspring by epigenetic programming of the hepatic LXRα-SREBP1 pathway, especially in the males. Show less

This study aims to investigate the effects of aged male parents on the learning ability of offspring and the intervention effect of Wuzi Yanzong Pills based on the microRNA-34a-5p(miR-34a-5p)/silent information regulator 1(SIRT1) signaling pathway. Thirty-two SD male rats of 15 months old were randomized into aged model, model+high-dose(8 g·kg~(-1)) Wuzi Yanzong Pills, model+low-dose(2 g·kg~(-1)) Wuzi Yanzong Pills, and model+vitamin C(100 mg·kg~(-1)) groups(n=8). In addition, 8 SD male rats of 3 months old were selected as the control group. Rats in treatment groups were fed the diets containing different doses of Wuzi Yanzong Pills or vitamin C, and the control and model groups received a regular diet for 12 weeks. After 5 days of co-caging with 3-month-old female mice, the fertilization rate was recorded. An automated sperm analyzer was used to examine the sperm motility and count, and the testicular spermatogenesis was assessed by hematoxylin-eosin staining. The senescence cells in the testicular tissue was detected by β-galactosidase staining, and miR-34a-5p expression was quantified via qPCR. The litter size was counted, and the body mass and body length were measured on days 1 and 30 to assess offspring development. For the offspring of 30 days old, their learning ability was examined via Morris water maze, and Nissl staining was employed to count hippocampal neurons. The miR-34a-5p expression in the hippocampal tissue of the offspring was determined by qPCR, and the protein levels of brain-derived neurotrophic factor(BDNF) and SIRT1 were determined by Western blot. Compared with the control group, the model group exhibited reductions in fertility rate, litter size, and sperm motility and count, as well as impaired testicular spermatogenesis(P<0.01). In addition, the model group showed increased senescence cells in testicular and epididymal tissue, accompanied by elevated miR-34a-5p expression in sperms. The 30-day-old offspring showed slow growth, reduced hippocampal neurons, up-regulated miR-34a-5p expression, and down-regulated protein levels of SIRT1 and BDNF in the hippocampus(P<0.01), along with impaired learning and memory performance(P<0.01). Compared with the model group, both high-dose Wuzi Yanzong Pills and vitamin C improved the fertilization rate, litter size, sperm motility, sperm count, and testicular spermatogenesis(P<0.05). The 30-day-old offspring in the two groups showed accelerated growth and development, increased hippocampal neurons, and elevated BDNF protein level in the hippocampus(P<0.05), along with enhanced learning and memory capabilities(P<0.05). Compared with the vitamin C group, the high-dose Wuzi Yanzong Pills group exhibited accelerated offspring growth(P<0.05), increases in fertilization rate and litter size(P<0.05), and improved learning and memory abilities(P<0.05). These findings indicate that Wuzi Yanzong Pills can improve testicular spermatogenesis and sperm quality in aged rats, thereby enhancing offspring's learning and memory performance. Specifically, Wuzi Yanzong Pills regulate miR-34a-5p expression to delay spermatogenic cell senescence in the testicular tissue and improve the offspring's cognitive function by miR-34a-5p mediated intergenerational transmission.

Glycolysis-derived lactate serves as a substrate for lysine lactylation, an epigenetic modification playing critical transcriptional regulatory roles in inflammatory diseases. Endothelial inflammation, characterized by upregulated glycolysis, initiates atherosclerosis, yet the contribution of histone lactylation remains undefined. Although narciclasine exhibits anti-inflammatory and antioxidant properties, its impact on endothelial inflammation in atherosclerosis is unknown. Connectivity Map (CMap) analysis predicted narciclasine as an inhibitor of oscillatory shear stress and TNF-α-induced endothelial inflammation. In vitro, treatment of human umbilical vein endothelial cells (HUVECs) with 20 nM narciclasine significantly suppressed ox-LDL-induced expression of VCAM1, ICAM1, SELE, and CCL2, reduced reactive oxygen species (ROS) production, and inhibited monocyte adhesion and migration.

Angiopoietin-like 4 (ANGPTL4) is a hepatokine involved in metabolism and inflammation and has been implicated in oncogenesis, yet its relationship with cancer risk in humans remains unclear. We analyzed 35,716 cancer-free UK Biobank participants with baseline plasma ANGPTL4. Multivariable Cox models and restricted cubic splines assessed associations with 24 site-specific incident cancers; bidirectional two-sample Mendelian randomization (MR) evaluated causality. During a median follow-up of 12.5 years, 9304 incident cancer cases occurred. Compared with the lowest quartile (Q1), the higher quartiles (Q2, Q3, and Q4) of ANGPTL4 levels were significantly associated with the risks of ten cancers, including cancers of the bladder, breast, cervix uteri, colorectum/anus, esophagus, kidney, liver, mesothelial/soft tissues, multiple myeloma, and ovary (hazard ratios ranging from 1.02 to 3.98). Risks generally increased across ANGPTL4 quartiles, and spline analyses supported approximately linear dose-response patterns. Adding ANGPTL4 to an age-sex model improved discrimination across several sites (ΔC-index 0-0.071), with statistical significance observed only for breast cancer. Associations were directionally consistent but heterogeneous by age, sex, and BMI. Forward MR provided no evidence that genetically proxied ANGPTL4 causally increases cancer risk. In reverse MR, genetic liability to liver cancer showed a nominal positive association with circulating ANGPTL4, suggesting ANGPTL4 may be elevated as part of tumor-related biology. Higher circulating ANGPTL4 is associated with increased risk of multiple cancers, with sex-and tissue-specific heterogeneity. Although MR does not support a universal causal role, ANGPTL4 remains a promising pan-cancer biomarker for risk stratification and early prevention. Show less

Atherosclerosis, a major contributor to cardiovascular diseases, is characterized by chronic inflammation in arterial walls. The role of NF-κB signaling in this process is well-established, but the upstream regulators remain incompletely understood. This study explored the role of TRIM47, an E3 ubiquitin ligase, in promoting atherosclerosis through NF-κB activation. In vitro studies used human umbilical vein endothelial cells (EC) treated with oxidized low-density lipoprotein (ox-LDL). TRIM47 expression was modulated using siRNA knockdown and overexpression plasmids. Inflammation markers, cell viability, and NF-κB activation were assessed. In vivo studies utilized ApoE-/- mice fed a high-fat diet and treated with adenovirus-mediated TRIM47 knockdown. ox-LDL treatment increased TRIM47 expression in EC, alongside elevated inflammatory markers, and reduced cell viability. TRIM47 overexpression exacerbated ox-LDL-induced inflammation, while knockdown attenuated these effects. Mechanistically, TRIM47 directly interacted with IκBα, promoting its ubiquitination and degradation, leading to enhanced NF-κB activation. In ApoE-/- mice, TRIM47 knockdown significantly reduced atherosclerotic plaque formation and lesion size. This study identified TRIM47 as a novel regulator of atherosclerosis progression through IκBα ubiquitination and NF-κB activation. TRIM47 knockdown attenuated vascular inflammation and atherosclerotic plaque formation. The findings suggested that TRIM47 might be a potential therapeutic target for the treatment of atherosclerosis and related cardiovascular diseases. Show less

Microglia-neuron contacts have been shown to regulate neural network activity through the formation and elimination of synapses. The pathogenesis of major depressive disorder is accompanied by a decline in brain-derived neurotrophic factor (BDNF) signaling, associated with increased microglia activity that disrupts cognitive function. The actions of both typical and rapid-acting antidepressant drugs, which have been shown to increase BDNF signaling through the tropomyosin receptor kinase B (TrkB) receptor, decrease microglia activation and the levels of pro-inflammatory cytokines. Examining the link between BDNF signaling and the microglial pro-inflammatory response, we demonstrate that TrkB signaling elicits the neuronal secretion of CD22 (Siglec-2), a sialic acid-binding immunoglobulin-type lectin, to inhibit microglial activation and alleviate depression-like symptoms. In a male chronic mild stress (CMS) mouse model of depression decreased expression of the postsynaptic scaffolding protein PSD-95 and Gαi1/3 were found to compromise TrkB signaling leading to reduced CD22 levels in hippocampal tissue. Restoration of TrkB-Gαi1/3-Akt signaling with dSyn3, a peptidomimetic compound targeting the PDZ3 domain of PSD-95, enhanced CD22 expression to inhibit microglial activation, promote dendritic spine formation and rapidly mitigate depression-like symptoms. Furthermore, hippocampal overexpression of CD22 in neurons was sufficient to reduce microglial activation and depressive-like behaviors in male CMS mice. S-ketamine, a rapid-acting antidepressant, increased CD22 expression to mitigate depression-like symptoms. While neuronal knockdown of CD22 in the hippocampus did not significantly impair the rapid (within 4 h) antidepressant effects typically observed with S-ketamine or dSyn3 administration, strikingly, knockdown of CD22 attenuated the long-acting (within 3 days) antidepressant effects of S-ketamine or dSyn3, as evidenced by sustained immobility in the TST (tail suspension test) and FST (forced swim test), and a lack of improvement in sucrose preference. In contrast, a single dose of fluoxetine failed to increase CD22 expression or inhibit microglia activity. These results suggest that rapidly-acting anti-depressant drugs enhance TrkB-induced neuronal expression and secretion of CD22 to promote the homeostatic state of microglia required for antidepressant actions. In male depression mice, dSyn3 facilitates BDNF-induced TrkB-PSD-95-Gαi1/3 complex formation to increase Akt-mTOR activation as well as synaptic and spine density in the hippocampus. TrkB signaling increases CD22 expression and secretion from neurons blocking microglial activation in the hippocampal region of male CMS mice. Show less

Compound Nujia honey paste (Nujia), a classic formulation from Traditional Uyghur Medicine, has been historically used for depression treatment and is listed in the Catalog of Ancient Classical Famous Formulas issued by the National Administration of Traditional Chinese Medicine and the National Medical Products Administration. Clarifying its pharmacodynamic material basis is essential for understanding its efficacy, yet this remains incompletely characterized. This study aimed to systematically elucidate Nujia's antidepressant efficacy and mechanisms by combining chemical analysis, computational prediction, and experimental validation in a CUMS rat model, providing a comprehensive approach to understanding its action. This study employed LC/MS to analyze the chemical constituents and blood-absorbed compounds of Nujia. This was combined with network pharmacology and molecular docking to predict and verify its potential antidepressant targets and signaling pathways. Using behavioral tests, ELISA, histopathology, Western blot, and qRT-PCR in a CUMS rat model, the research thoroughly evaluated Nujia's therapeutic effects and mechanisms, fostering trust in the findings. In this study, LC/MS analysis identified 124 chemical constituents from Nujia, and further analysis determined 26 blood-absorbed compounds (including 10 prototype compounds). Network pharmacology analysis revealed that its potential antidepressant effects are closely associated with core targets such as AKT1 and TNF, a prediction subsequently verified by molecular docking results. In the CUMS-induced rat model of depression, intervention with Nujia significantly ameliorated depression-like behaviors in the animals and alleviated neuropathological damage in the hippocampus and prefrontal cortex. Mechanistic investigations revealed that Nujia upregulated the levels of monoamine neurotransmitters (5-HT, DA, NE) and neurotrophic factors (BDNF, NGF) in serum, while downregulating the expression of pro-inflammatory cytokines (TNF-α, IL-1β, IL-6, IL-18). Further molecular experiments confirmed that Nujia likely mitigates neuroinflammation by inhibiting the TNF-α/NF-κB signaling pathway, and inhibits neuronal apoptosis by activating the PI3K/AKT signaling pathway and its downstream anti-apoptotic proteins. Furthermore, Nujia significantly upregulated the expression of key synaptic plasticity proteins (SYP, GAP43, and PSD95) in hippocampal tissue, thereby enhancing synaptic structure and function. These findings underscore the complex, multi-target mechanisms underlying Nujia's antidepressant effects, encouraging further exploration of its therapeutic potential. This study systematically elucidates that Nujia achieves its antidepressant therapeutic effects by mediating multi-pathway synergistic actions, including but not limited to the TNF-α/NF-κB and PI3K/AKT signaling pathways, to ameliorate neuroinflammation, attenuate apoptosis, and enhance synaptic plasticity.

The protein corona formed upon systemic administration critically modulates the pharmacokinetics, biodistribution, and therapeutic efficacy of the nanomedicines. While emerging evidence links obesity to heightened chemosensitivity, the underlying nanobio-interfacial mechanisms remain poorly understood. Herein, we demonstrate that pegylated liposomal doxorubicin (PLD) exhibits significantly enhanced antitumor and antimetastatic efficacy in obese breast tumor-bearing mice compared to normal controls. Mechanistic investigations reveal that obesity confers PLD with prolonged systemic circulation and improved tumor accumulation. Notably, preincubation of PLD with plasma from obese mice reduces macrophage uptake while promoting internalization by breast cancer cells compared to that from normal mice. Genetic ablation of apolipoprotein E (ApoE) in obese mice abolishes obesity-associated improvements in PLD blood circulation, tumor accumulation, and uptake by cancer cells. Conversely, supplementation with recombinant ApoE restores these effects in ApoE-deficient mice and potentiates PLD's antitumor efficacy. Collectively, our findings demonstrate obesity-induced ApoE as a pivotal regulator of the protein corona that actively enhances tumor-targeted delivery of PLD, which offers a rational strategy for engineering protein-corona-mediated tumor-targeted nanomedicines.

Metabolic dysfunction-associated steatotic liver disease (MASLD) is a serious chronic liver disease with limited therapeutic options. Fibroblast growth factor (FGF) analogs show promising therapeutic benefits for MASLD, yet the underlying mechanisms remain incompletely understood. Here, we studied the mechanism underlying the anti-steatotic properties of FGF1, the prototype member of the FGF family. The effect of FGF1 was studied in human and rodent hepatocytes and in obese mouse models exhibiting acute or chronic endoplasmic reticulum (ER) stress characteristic of MASLD. Metabolic analysis and proteomics were applied to evaluate liver physiology, ER stress and signaling. We show that FGF1 reduces hepatic triglyceride (TG) levels in obese mice (51%, These results define ER stress-dependent modulation of VLDL secretion as a mechanism underlying the anti-steatotic activity of FGF1. Targeting the FGF-UPR pathway may thus have therapeutic potential for treating MASLD. Fibroblast growth factors show therapeutic potential in both preclinical models and clinical trials for treating metabolic dysfunction-associated steatotic liver disease, a highly prevalent condition with limited treatment options. Identifying the mechanisms underlying their anti-steatotic effects may accelerate clinical development. Our finding that triglyceride secretion is the major driver of the anti-steatotic action of FGF1, together with the involvement of an adaptive unfolded protein response, provides deeper insight into the therapeutic potential of this pathway. These results also highlight possible implications for liver physiology and for the circulating lipoprotein profile, with relevance for both efficacy and safety considerations. Show less

Alcohol use disorder (AUD) is a chronic condition marked by compulsive drinking and withdrawal-related negative affect. Histamine (HA) signaling, particularly via the histamine H3 receptor (H3R), may modulate alcohol-related behaviors. We investigated the effects of pitolisant, an FDA-approved H3R antagonist, on ethanol (EtOH)-related behaviors in mice. Adult male C57BL/6J mice underwent acute or chronic (2 or > 8 weeks) intermittent alcohol exposure. Pitolisant pretreatment was administered, and then pharmacological behavior, histologic, and molecular assays were conducted. Pitolisant administration reduced acute EtOH-induced locomotor activation, conditioned place preference, and sedative effects, and also curtailed EtOH intake. It alleviated anxiety and depression-like behavior during 24-h withdrawal (Post-EtOH). Mechanistically, the Post-EtOH condition was featured by complicated brain cFos expression mapping, including elevated cFos, [HA] and [glutamine]/[glutamate] ratio in the lateral habenula (LHb). However, systemic pitolisant treatment significantly increased [norepinephrine]/[normetanephrine] ratio, and restored the diminished phosphorylated CREB and BDNF levels in the LHb. Intra-LHb H2R antagonist cimetidine infusion partly blocked the pitolisant therapeutic effect on alcohol-related behavior. These findings highlight the HAergic system as a critical regulator of alcohol-related behaviors. The LHb HA signaling and norepinephrine neurotransmission might underlie pitolisant's potential novel therapeutic strategy for AUD. Show less

Sodium perfluorononenoxybenzene sulfonate (OBS), a substitute for perfluorooctane sulfonate (PFOS), has been frequently detected in the environment and human blood. Although OBS exposure has been identified as a novel risk factor for atherosclerosis associated with endothelial dysfunction, the underlying molecular mechanisms remain unclear. In this study, in vitro experiments using human umbilical vein endothelial cells (HUVECs) demonstrated that OBS exposure induced oxidative stress, activated the PERK-eIF2α-ATF4 axis of endoplasmic reticulum stress (ERS) and triggered NF-κB signaling. Pharmacological inhibition with N-acetylcysteine (NAC, an antioxidant), 4-phenylbutyric acid (4-PBA, an ERS inhibitor), and BAY 11-7082 (an inhibitor for NF-κB signaling pathway) revealed a sequential pathogenic cascade, in which oxidative stress acts upstream to initiate ERS and compromise endothelial barrier function, leading to NF-κB activation, which drives inflammatory responses, monocyte adhesion, and impaired endothelial migration. Consistent with these findings, in vivo experiments in ApoE Show less

Cerebral microbleeds (CMBs) have been found to promote Alzheimer's disease (AD) progression. Hypertension (HTN) is one of the major etiological factors for CMBs and an important risk factor for AD. However, the association between HTN-related CMBs and AD pathology remains undetermined. This study aims to identify the relationship between HTN-related CMBs and amyloid-β 42 (Aβ42) and β-site amyloid precursor protein cleaving enzyme 1 (BACE-1) levels in plasma astrocyte-derived exosomes (ADEs). In total, 88 HTN participants including 30 with deep/infratentorial (D/I) CMBs, 30 with mixed CMBs, and 28 without CMBs were analyzed. Susceptibility-weighted imaging was performed to assess the location, presence, and number of CMBs. ELISA kits for BACE-1 and Aβ42 were employed to evaluate the levels of astrocyte-derived exosomal proteins. The results indicated that plasma ADE levels of Aβ42 were reduced in the HTN + D/I CMBs and HTN + Mixed CMBs groups relative to the HTN-CMBs group. Furthermore, the plasma ADE levels of Aβ42 were significantly associated with CMBs in patients with HTN. However, no significant differences were found in the plasma ADE levels of BACE-1 among the HTN + D/I CMBs, HTN + Mixed CMBs, and HTN-CMBs groups. The study revealed that reduced plasma ADE levels of Aβ42 were significantly associated with CMBs in HTN patients. This finding suggests a potential link between HTN-related CMBs and AD-related amyloid-β pathology, offering novel insights into the mechanisms by which HTN-related CMBs promote AD progression.

Atherosclerosis (AS) is a chronic vascular disease and the principal cause leading to ischemic cardiomyopathy (ICM). It involves complex metabolic dysregulation beyond the resolution of single-omics. Emerging evidence implicates arginine-proline metabolism (APM) in driving inflammation and impairing efferocytosis, yet the cellular basis of plaque instability remains elusive. We employed a five-stage analytical framework. First, metabolomic profiling revealed shared pathways between AS and ICM. Second, single-cell RNA sequencing identified APM-enriched macrophage subtypes in both diseases. Pseudotime analysis, Scissor algorithm, and cell-cell communication analyses linked these subtypes to APM signaling, stroke prognosis, and key ligand-receptor interactions. Third, cNMF and unsupervised clustering defined APM-related gene signatures in macrophages, validated by survival analysis. Fourth, spatial transcriptomics confirmed their spatial distribution and colocalization within unstable plaques. Finally, key biomarkers were validated in atherosclerotic lesions using ApoE Metabolomic profiling revealed APM as a shared dysregulated pathway in AS and ICM. We identified a macrophage subset (SPP1⁺ macrophages and mono-macrophages), termed APM_high macrophages, enriched in the fibrous cap and characterized by elevated collagenase activity, heightened inflammation, and disrupted cholesterol homeostasis. Spatial and cell-cell communication analyses revealed strong interactions with dendritic cells via the MIF-(CD74 + CXCR4) axis, potentially contributing to plaque destabilization. Transcriptomic clustering uncovered a high-APM plaque subtype associated with worse ischemic outcomes. Six diagnostic biomarkers were identified through machine learning and validated across multiple cohorts and in ApoE In summary, our study decodes the metabolic basis of inflammation shared between AS and ICM, suggesting an APM_high macrophage-centered regulatory axis across multiple omics layers. This work advances our understanding of the cardio-metabolic axis and suggests new avenues for targeted therapy. Show less

Gastric cancer (GC) is a leading cause of cancer-related deaths and has high recurrence rate. Although fibronectin domain-containing protein 1 (FNDC1) is implicated in GC progression, its molecular mechanisms remain unclear. Multi-omics analyses (TCGA, GEO datasets) were used to assess FNDC1 expression and clinical correlation. In vitro (cell proliferation, invasion, EMT markers) and in vivo (xenograft) experiments, combined with molecular assays (Co-IP, WB, ChIP), explored FNDC1's function and mechanism. FNDC1 was significantly upregulated in GC, correlating with advanced clinicopathological features and poor prognosis. Knockdown of FNDC1 suppressed GC cell proliferation, invasion, and metastasis by inhibiting EMT and Wnt/β-catenin signaling. Mechanistically, FNDC1 competitively bound the WD5 domain (residues 224-254) of Gβ2, disrupting Gβγ-Dvl1 interaction. This prevented Dvl1 degradation, promoted Axin1 ubiquitination, and destabilized the β-catenin-destruction complex (GSK3 β-APC-Axin1), leading to β-catenin accumulation and Wnt pathway activation. FNDC1 drives GC malignancy by targeting the Gβ2-Dvl1 axis to activate Wnt/β-catenin signaling, suggesting FNDC1 as a novel prognostic biomarker and therapeutic target. Show less

Atherosclerosis is fundamentally a pathology of unresolved inflammation perpetuated by the collapse of Regulatory T cell (Treg)-mediated tolerance. Emerging evidence indicates that Treg functional integrity is intrinsically dictated by mitochondrial fatty acid oxidation (FAO), a metabolic checkpoint often compromised under systemic metabolic stress. Current lipid-lowering therapies, such as statins, often fall short in correcting this maladaptive immunometabolic defect and may introduce collateral metabolic perturbations. This study aimed to elucidate the immunometabolic therapeutic mechanism of Dingxin Recipe III (DXR III) in ameliorating atherosclerosis. We employed an integrated systems pharmacology strategy-combining serum pharmacochemistry, multi-omics profiling, and extensive high-dimensional flow cytometry-to elucidate the therapeutic mechanism of DXR III, a traditional Chinese herbal formula in an in vivo study. ApoE DXR III treatment effectively attenuating atherosclerotic progression. Serum pharmacochemistry identified 254 prototypical absorbed constituents, including Tanshinone I (a potential Peroxisome Proliferator-Activated Receptor Gamma agonist), as bioactive candidates. Multi-omics analysis revealed that DXR III modulated the metabolic environment, coinciding with restored FAO flux. This shift was associated with a favorable metabolic niche characterized by increased FAO substrates, which correlated with the rescue of Treg differentiation and phenotypic stability. Specifically, DXR III facilitated the redistribution of Tregs from the spleen to plaque sites and significantly inhibited their trans-differentiation into Th1-like or Th17-like phenotypes. Conversely, Simvastatin treatment, despite lowering lipids, resulted in peripheral Th17 accumulation and failed to alleviate hyperglycemia. In contrast, DXR III maintained Th17 homeostasis-abolishing the pathogenic non-classical Th17 subset-and exerted dual-regulatory effects on both lipid and glucose metabolism. DXR III ameliorates atherosclerosis, a process closely associated with the modulation of the FAO metabolic checkpoint to correct the immune imbalance driving plaque progression. By rescuing the Treg differentiation, functional integrity, and phenotypic fidelity while avoiding the immunological trade-offs associated with Th1/Th17, DXR III represents a promising candidate for comprehensive cardiovascular protection.
