Atherosclerosis is a chronic and progressive inflammatory disease that can lead to adverse cardiovascular and cerebrovascular events. Phenotypic switching of vascular smooth muscle cells (VSMCs) plays a pivotal role in its development and progression, but the upstream regulatory mechanisms remain incompletely defined. Here, we identify ubiquitin-fold modifier 1 (UFM1), a ubiquitin-like protein, as a critical regulator of VSMCs plasticity and atherogenesis. In VSMCs stimulated with oxidized low-density lipoprotein (ox-LDL), UFM1 overexpression markedly attenuated phenotypic switching, restoring contractile features and suppressing synthetic activation, accompanied by reduced proliferation and migration. In contrast, UFM1 knockdown further exacerbated these phenotypic alterations. In ApoE Show less

Scavenger receptor B3/differentiation cluster 36 (SCARB3/CD36) has been established as a fatty acid transporter and genetic deficiency of CD36 in mice models shows decreased uptake of oxidized low-density lipoprotein (oxLDL) and reduced atherosclerosis. The present study proposes CD36 as a drug target inhibited by leonurine to alleviate inflammation and prohibit unstable atherosclerotic plaques. We showed that the anti-atherosclerotic effects of leonurine were dependent on CD36 in a mice model of arterial atherosclerosis induced by tandem stenosis surgery fed with Western diet (TS + WD) established in both wild type (WT) and Cd36 Show less

Blood-based biomarkers are increasingly used to characterize Alzheimer's disease (AD)-related pathology, yet substantial heterogeneity exists in how biomarker burden relates to cognitive performance. Grip strength, a marker of frailty and functional reserve, may modify this relationship. We conducted a cross-sectional analysis of 348 participants from the Aging Adult Brain Connectome (AABC) study. Global cognition was assessed using the Preclinical Alzheimer Cognitive Composite (PACC). Plasma biomarkers included phosphorylated tau-217 (pTau Show less

Both Apolipoprotein E-ε4 (APOE-ε4) and astrocytic activation, as measured by glial fibrillary acidic protein (GFAP), play critical roles in Alzheimer's disease (AD). However, the influence of astrocytic activation on the relationship between APOE-ε4 and AD pathologies remains unclear. This study investigates the interrelationships among astrocytic activation, APOE-ε4, and AD pathophysiology in 529 participants who underwent plasma biomarker measurements, APOE genotyping, and cognitive testing. Additionally, 277, 284, and 104 underwent structural magnetic resonance imaging (MRI), amyloid-β (Aβ) positron emission tomography (PET), and tau PET, respectively. The associations of plasma GFAP, APOE-ε4, and AD-related biomarkers, as well as whether plasma GFAP mediates APOE-ε4-related effects on AD, were investigated. Higher plasma GFAP and APOE-ε4 were independently associated with more severe Aβ and tau aggregation, as well as cognitive decline. Mediation analyses showed a significant indirect effect of APOE-ε4 on plasma p-tau biomarkers (21.1%-24.9%), Aβ PET (16.4%), and cognition (19.6%), while the indirect effect on tau PET was trend-level (29.1%, p Show less

Hypercholesterolemia and a high-fat diet promote 2 macrophage subtypes involved in atherosclerosis by inducing lipid droplet accumulation in foamy macrophages (FMs) and inflammatory activation in non-foamy macrophages (NFMs). MicroRNAs are key regulators of macrophage function; for instance, The role of Unlike FMs, NFMs are primarily located in the plaque core and show higher Show less

Social isolation (SI) is an established risk factor for Alzheimer's disease (AD) and cognitive decline. However, its stage-specific effects across the AD continuum, particularly at subjective cognitive decline (SCD) and mild cognitive impairment (MCI) stages, remain unquantified in Chinese populations. The sex-specific effects of SI on cognitive decline remain incompletely characterized. The apolipoprotein E ( To investigate social connection characteristics and gene distribution in individuals with SCD or MCI, examine their cross-sectional associations with cognitive function, and explore gender differences in SCD or MCI risk/prevention. A community-based sample of 164 SCD and 84 MCI patients (July 2021-Dec 2024) was assessed. Demographic, social connectivity, LSNS-6 scores showed weak-to-moderate correlations with Montreal Cognitive Assessment ( SI may exacerbate cognitive dysfunction in adults with SCD or MCI.

Endothelial cells under oxidative stress and inflammation are vital contributors to the progression of atherosclerosis. Although Orientin possesses antioxidant and anti-inflammatory activities, the effects of Orientin on oxidized low-density lipoprotein and high glucose (ox-LDL/HG)-triggered endothelial cell injury and diabetes-accelerated atherosclerosis remain unclear.

Alzheimer's disease (AD) is an irreversible neurodegenerative disease defined by its molecular hallmarks - amyloid beta peptide plaques and neurofibrillary Tau tangles. Despite significant progress that has been made in uncovering a large number of genetic risk factors through extensive genomic sequencing and genetic studies, the molecular mechanisms driving AD-associated pathology and cognitive decline remain poorly understood. Therefore, alongside the identification of more risk genes, it is also paramount to study how these genes function and influence each other within the cellular pathways and overall molecular networks in AD-relevant brain cell types. However, current human protein-protein interactome datasets were all generated in either yeast or generic human cell lines. Consequently, many important neuronal interactions, especially neuron-specific ones, have yet been discovered. To address this critical gap, we developed a highly scalable, high-quality interactome mapping pipeline in human excitatory neurons derived from induced pluripotent stem cells (iPSC), and generated a comprehensive, neuron-specific interactome map, named ADNeuronNet, for key AD risk genes. ADNeuronNet consists of 1,767 high-confidence interactions among 1,189 proteins and is the only dataset enriched with neuron-specific genes when compared to known protein interactions, including previous large-scale interactome maps, for the same baits in the literature. Within ADNeuronNet, we identified 1,375 novel interactions, many of which are likely neuron specific. For example, we identified a neuron-specific interactor, RIN2, for major AD risk factor BIN1 and confirmed RIN2's function in recruiting BIN1 to RAB5 positive early endosomes, a process that has been well-associated with AD etiology. Additionally, we performed quantitative interaction perturbation analyses on AD risk genes with AD-associated mutations or isoforms and identified significant changes in 99 protein interactions among 11 different protein variants. Finally, we found that subunits from the anaphase-promoting complex/cyclosome (APC/C), another novel BIN1 interactors identified by ADNeuronNet, mediated modulation of Tau-aggregation in neurons via regulation of APOE expression, uncovering a previously unrecognized BIN1-APC/C-APOE regulatory axis in AD pathobiology. In summary, these findings illustrate how our neuron-specific ADNeuronNet can be leveraged to uncover new risk gene candidates and cellular pathways that help advance our understanding of molecular mechanisms underlying AD etiology.

Dietary protocatechuic acid (PCA) inhibits atherosclerosis development in male ApoE-/- mice. However, its anti-atherosclerotic property in genetically unmodified (wild-type) male or female mice remains unknown.Five-week-old C57BL/6J mice (half males and females) were divided into negative (fed a chow diet), positive (fed an atherogenic diet), or 5, 25, 50, 100, or 200 mg/kg BW/d of PCA (fed an atherogenic diet) groups. Oral gavage with PCA between 25-100 mg/kg BW/d for 25 weeks significantly attenuated atherogenic diet-induced plaque formation in a dose-dependent manner, whereas the anti-atherosclerotic efficiency of 200 mg/kg BW/d of PCA was comparable with that of 50 mg/kg BW/d. PCA did not affect serum lipids (total triglyceride, total cholesterol, HDL cholesterol), pro-inflammatory cytokines (tumor necrosis factor alpha, IL-1b, IL-6), oxidized LDL, and total antioxidant capacity, and acetylcholine or sodium nitroprusside-induced aortic relaxation. Instead, PCA (≥25 mg/kg BW/d) reduced macrophage accumulation and content of tumor necrosis factor alpha, superoxide, and 4-hydroxynonenal within plaques, and inhibited monocyte adhesion to aortic endothelium in both male and female mice.PCA inhibits early atherosclerosis formation in both male and female C57BL/6J mice with a "U-shaped" dose-response relationship, possibly by reducing inflammation burden and oxidative stress within atherosclerotic plaques.

Atherosclerosis is a common vascular disease that poses a serious threat to global health. However, the mechanism underlying the pathogenesis and progression of atherosclerosis remains elusive. We analysed the expression of deubiquitinating enzymes in human atherosclerotic lesions and found that USP25 was significantly downregulated. The role of USP25 in atherosclerosis was validated in mouse models with an ApoE USP25 was predominantly expressed in macrophages in atherosclerotic lesions, and ablation of macrophagic USP25 significantly exacerbated atherosclerosis in ApoE This study elucidated the function and molecular mechanism of USP25 in atherosclerosis, identifying USP25 as a beneficial regulator for this disease.

Atherosclerosis, a chronic inflammatory disease, is the most relevant cause of ischaemic stroke or myocardial infarction. Vascular endothelial cells (ECs) play a significant role in the development of atherosclerosis. In this chronic inflammatory environment, we aimed to investigate whether a Evolocumab (Evb) could mitigate atherosclerosis progression by inhibiting EC activation via in vivo and in vitro assays. In vivo, we investigated the ability of Evb to prevent atherosclerotic lesion formation 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.

Lecanemab, an anti-amyloid beta (Aβ) protofibril antibody, was introduced in China in 2024, but its real-world performance remains unknown. In this prospective, multicenter study across 21 sites, 261 Alzheimer's disease patients (mild cognitive impairment to moderate dementia) received biweekly lecanemab (10 mg/kg). A matched Alzheimer's Disease Neuroimaging Initiative (ADNI) cohort served as comparator. Cognitive tests, plasma biomarkers, and optional amyloid/tau positron emission tomography (PET) were assessed over 6 months. Lecanemab significantly attenuated cognitive decline versus ADNI. Plasma Aβ42, Aβ40, phosphorylated tau 217 (p‑tau217), glial fibrillary acidic protein (GFAP), and ratios showed robust changes; a p‑tau217 reduction correlated with amyloid PET clearance (mean -22.1 Centiloid; 29.2% turned amyloid-negative). Apolipoprotein E (APOE) ε4 non-carriers showed greater improvements. Infusion reactions occurred in 11.1% and amyloid-related imaging abnormalities in 9.2% (1.6% symptomatic), with no stage-related safety differences. Lecanemab was effective and well tolerated in real-world Chinese patients. Plasma p‑tau217 may serve as a sensitive, minimally invasive treatment-response biomarker. Show less

Antihypertensive medications (AHMs) may modulate Alzheimer's disease (AD) pathogenesis via cerebrovascular or neuroinflammatory pathways, yet evidence remains conflicting. This study investigated causal associations between AHM use and AD risk, focusing on drug classes, blood pressure status, and apolipoprotein E epsilon 4 (APOE ε4) effects. We integrated genetic causal inference with longitudinal survival analyses in a dual-evidence framework. Mendelian randomization (MR) was used to estimate class-specific causal effects at the population level. To examine effect modification by genetic and clinical factors, we analyzed 532 cognitively normal or mildly impaired older adults in ADNI with baseline assessments, with time-to-AD conversion modeled using Cox regression stratified by hypertension history and APOE ε4 status. Overall antihypertensive use showed no significant association with AD risk in hypertensive individuals (HR = 0.71) or APOE ε4 carriers (HR = 0.72). However, ARBs demonstrated protective associations in APOE ε4 carriers (HR = 0.32, 95% CI: 0.12-0.86). MR analysis supported causal protective effects for angiotensin II receptor blockers (ARBs, OR = 0.94, 95% CI: 0.89-0.98), calcium channel blockers (CCBs, OR = 0.93, 95% CI: 0.90-0.97), and beta-blockers (BBs, OR = 0.92, 95% CI: 0.86-0.98), whereas ACEIs lacked MR support and thiazide diuretics showed no benefit. Our findings reveal class-specific antihypertensive effects on AD risk. ARBs demonstrated the strongest protection, particularly in APOE ε4 carriers, while BBs and CCBs showed neuroprotective benefits. Results suggest AD prevention involves mechanisms beyond blood pressure reduction alone, supporting precision medicine with genotype-guided antihypertensive selection for genetically vulnerable individuals.

Alzheimer disease (AD) is a progressive neurodegenerative disorder that predominantly affects the aging population. Anti-amyloid β (anti-Aβ) therapies, such as lecanemab, have been developed to slow disease progression.

Vitiligo pathogenesis involves progressive melanocyte loss and keratinocyte dysfunction, which are driven primarily by oxidative stress resulting from excessive ROS accumulation. We engineered a temporally controlled hydrogel microneedle system that integrates ginseng-derived exosomes (G-Exos) with biomimetic polydopamine nanoparticles (PDA@PEGs) to concurrently target the pathogenic triad of vitiligo, including oxidative stress, inflammation, and melanocyte deficiency. This system employs methacrylated hyaluronic acid (HAMA) hydrogel microneedles for rapid PDA@PEG release while utilizing glyceryl monostearate micelles to achieve matrix metalloproteinase-9 (MMP-9)-responsive G-Exo release at inflammatory foci, enabling intelligent spatiotemporal control. Functionally, G-Exos help restore redox homeostasis and suppress inflammation through bioactive constituents, thereby protecting melanocytes and enhancing keratinocyte proliferation. Moreover, PDA@PEG promotes repigmentation through the dual mechanisms of exogenous melanin deposition and endogenous melanogenesis stimulation. In murine models, this strategy achieves significant repigmentation within 3 weeks by activating follicular stem cells, upregulating melanogenic markers (Tyr/Mc1r), increasing antioxidant defense (ApoE), and suppressing inflammatory signaling (IL-17). This natural-biomimetic hybrid design leverages biocompatible materials to co-target multiple pathological axes, offering a novel self-adaptive approach for microenvironmental rehabilitation in vitiligo.

Glioblastoma (GBM) remains one of the most intractable malignancies owing to the dual challenges of the blood brain barrier (BBB) and profound immunosuppression. Here, we present a nanobomb (OMV-ApoE@ALF) that integrates heterologous production of the aromatic polyketide albofungin (ALF) with programmable outer membrane vesicles (OMVs) displaying ApoE peptides for GBM immunotherapy. OMV-ApoE@ALF efficiently crossed the BBB, accumulated in tumors, and functioned as a lysosomal nanobomb to boost pyroptosis and activate cGAS-STING pathway, thereby promoting dendritic cell maturation, T-cell infiltration, and durable antitumor immunity. Mechanistically, OMV-ApoE@ALF delivered ALF into lysosomes, inducing lysosomal disruption, reactive oxygen species (ROS) production, and subsequent mitochondrial damage. Crucially, this lysosomal rupture also suppressed protective autophagy of tumor cells themselves, thereby reinforcing the cascade activation between caspase-3/GSDME-dependent pyroptosis and cGAS-STING signaling pathway. This lysosomal disruption-nanobomb represents a new strategy for advancing GBM immunotherapy. Show less

Protocatechuic acid (PCA), a natural compound found in a variety of Chinese herbal medicines and plant foods, has been documented to inhibit atherosclerosis partially by reducing inflammation burden in arterial endothelial cells. Interestingly, in vitro studies showed that PCA at physiologically reachable concentrations does not affect inflammation burden in TNF-α-stimulated aortic endothelial cells, whereas it increases the content of exosomal miR-10b secreted by macrophages that have engulfed apoptotic cells (efferocytic macrophages). This study was aimed at investigating whether the in vivo anti-inflammatory effect of PCA in arterial endothelial cells was due to the uptake of efferocytic macrophage exosomal miR-10b. A transwell co-culture system of aortic endothelial cells with efferocytic macrophages was used to evaluate the effect of PCA on NF-κB-mediated inflammation in aortic endothelial cells. An inhibitor of exosome secretion, GW4869, was applied to confirm the role of exosomes played in the anti-inflammatory effect of PCA. The aortic endothelial cells were administrated with exosomes isolated from PCA-treated efferocytic macrophages or miR-10b mimic or antagomir to ascertain the role of miR-10b in downregulating inflammation effect of PCA. Bioinformatics analyses, loss-of- and gain-of-function assays and luciferase reporter gene assays were performed to identify targeting relationship between miR-10b and mitogen-activated protein kinase kinase kinase 7 (MAP3K7)/β-transducin repeat-containing protein (β-TrCP). Besides, Apoe PCA at physiologically reachable concentrations inhibited NF-κB-mediated inflammation in TNF-α-stimulated aortic endothelial cells co-cultured with efferocytic macrophages, in which treatment of GW4869 reversed this effect. Exosomes isolated from PCA-treated efferocytic macrophages inhibited inflammation and increased miR-10b levels in aortic endothelial cells. Mechanistically, exosomal miR-10b post-transcriptionally repressed MAP3K7 and β-TrCP, both of which promote NF-κB activation. Knockdown of Map3k7 and Btrc with siRNA in aortic endothelial cells abolished the inhibitory effects of exosomes isolated from PCA-treated efferocytic macrophages on NF-κB-mediated inflammation. Consistently, oral administration of PCA increased miR-10b level and inhibited Map3k7 and Btrc mRNA expression as well as inflammation in aortic endothelial cells in Apoe Our current findings suggest that PCA could transfer exosomal miR-10b from efferocytic macrophages to endothelial cells and thus inhibit NF-κB-mediated inflammation in arterial endothelial cells through repressing MAP3K7 and β-TrCP, two new targets of miR-10b.

Smooth muscle cells (SMCs) exhibit remarkable plasticity, undergoing extensive phenotypic switching to generate a highly heterogeneous population within atherosclerotic plaques. While recent studies have highlighted the contribution of SMC-derived macrophage-like cells to plaque inflammation, the specific molecular drivers governing the transition to these pathogenic states remain poorly understood. Here, we re-analyzed single-cell RNA sequencing data from lineage-traced mice to dissect SMC heterogeneity during atherogenesis. Trajectory analysis revealed that SMCs transdifferentiate into a distinct pro-inflammatory macrophage-like subpopulation (macrophage 4) via an intermediate "stem-endothelial-monocyte" cell state. Integrated gene regulatory network inference and Clinically, IRF7 expression was significantly upregulated in unstable and advanced human atherosclerotic plaques, correlating strongly with inflammatory macrophage burden. These findings identify IRF7 as a critical checkpoint in maladaptive SMC phenotype switching. We demonstrate that IRF7 drives the transdifferentiation of SMCs into a pro-inflammatory macrophage-like state, thereby fueling plaque instability. Consequently, therapeutic strategies capable of inhibiting IRF7-mediated SMC plasticity may prove effective in stabilizing vulnerable atherosclerotic plaques. Show less

Monocyte adhesion to vascular endothelial cells is a critical step in the pathogenesis of atherosclerosis. While unconventional myosins are known to participate in various cellular activities, their specific role in monocyte-endothelium adhesion remains unclear.In the present study, we investigated the effects of Myosin IF (Myo1f), a class I unconventional myosin, on atherosclerosis and its underlying mechanisms. A high-cholesterol diet was administered to apolipoprotein E-KO (Apoe Myo1f expression was found to be significantly increased in PBMCs of patients with coronary artery disease. Moreover, Myo1f-deficient mice exhibited a notable reduction in atherosclerotic plaque area and lipid deposition compared to Apoe Our data indicate that Myo1f regulates monocyte adhesion and contributes to the pathogenesis of atherosclerosis by recruiting EPLINα, which stabilizes F-actin. This stabilization enhances MRTFA nuclear translocation, thereby promoting ITGB2 transcription. Show less

Endothelial senescence contributes to the development and progression of atherosclerosis. Poliumoside (Pol), a natural compound with diverse bioactivities, has been shown to attenuate oxidative stress and inflammation, major triggers of senescence.

High levels of circulating interleukin (IL)-16 are associated with a reduced incidence of cardiovascular events. The disruption of atherosclerotic plaques commonly causes myocardial infarction and stroke. In this study, we investigated the effects of IL-16 on phenotypic modification of plaques. Mice with deficiencies in IL-16 and apolipoprotein E (IL16 IL-16 deficiency increased the necrotic core and reduced fibrous cap thickness in the plaques. IL-16 deletion accelerated the degradation of intraplaque collagen and elastin, increased matrixmetalloproteinase activity, and reduced TIMP-3 expression. Transplantation of wild-type IL-16 bone marrow into IL-16 knockout mice successfully attenuated the plaque instability caused by IL16 deficiency. Furthermore, hematopoietic-derived IL-16 activated the CD4/JAK2/STAT6 pathway and increased the binding of STAT6 to the coactivator cAMP-response element-binding protein (CBP)/p300 at the TIMP-3 promoter in smooth muscle cells (SMCs). Consequently, acetylation of STAT6 and histone H3 increased more than 2-fold, which caused a 2.2-fold upregulation of TIMP-3. Moreover, the anti-atherosclerotic effects of IL-16 on plaque stability were abrogated by the SMC-specific deletion of CD4, and the plaque vulnerability caused by IL-16 defects was reversed by SMC-specific overexpression of TIMP-3. IL-16/CD4/JAK2/STAT6 upregulates TIMP-3 expression in SMCs to remodel the intraplaque extracellular matrix toward a stable phenotype. Our findings suggest that IL-16 is a novel factor in vascular remodeling and atherosclerotic plaque phenotype modulation and is a potential target for intervention in the later stages of atherosclerosis.
