This study aims to investigate the effects of mulberry anthocyanin (MA) in high-fat and high-cholesterol (HFHC) diet-fed ApoE-/- mice. ApoE-/- mice were randomly divided into control (ACON), mulberry fruit anthocyanin extract (MFAE), cyanidin-3-glucoside (C3G) group 1 (C3GT), and C3G group 2 (C3GP). After 7 weeks of HFHC diet feeding and following 2-3 weeks of treatment, samples were collected and analyzed. The C3GT group significantly decreased low-density lipoprotein (7.3 ± 1.5 mmol/L) and interleukin-1β (355.4 ± 41.7 pg./mL) levels. Moreover, the MFAE (636.3 ± 90.7 pg./mL), C3GT (611.5 ± 65.4 pg./mL), and C3GP (757.5 ± 47.6 pg./mL) significantly increased glutathione peroxidase (GSH-PX) levels compared with those in the ACON group. The MA treatments significantly increased the number of MA treatment may attenuate AS-associated risk factors by decreasing inflammatory factor-related gut microbial genera. The mechanism may be related to regulating liver glutamine, ATP, and related metabolic pathways. Show less

Herpes simplex virus type 1 (HSV-1) is a neurotropic pathogen capable of invading the central nervous system (CNS) and increasingly associated with chronic neuroinflammation, cognitive impairment, and neurodegenerative disease. While microglia orchestrate the initial immune response to HSV-1, the molecular mechanisms that regulate their sustained neuroinflammatory activity To define the transcriptional and epigenetic mechanisms that shape microglial responses during acute HSV-1 infection Single-cell multiome analysis of CD11b⁺ nuclei identified transcriptionally and epigenetically distinct microglial and macrophage populations. HSV-1 infection redistributed monocyte-lineage states, with a marked overrepresentation of interferon (IFN)-responsive microglia and macrophage-associated populations. These states exhibited amplification of STAT1/2-, IRF1-, and CEBPB-centered regulons, distinguishing IFN-responsive microglia from macrophage-enriched populations rather than reflecting uniform activation. Homeostatic microglial gene signatures ( Using a multiomic framework, we demonstrate that HSV-1 infection drives transcriptional and epigenetic remodeling of microglial populations, characterized by a dominance of IFN-responsive states and a loss of homeostatic signatures. These findings provide mechanistic insight into how localized viral infection can reprogram microglial regulatory landscapes to maintain persistent HSV-1-associated neuroinflammation, contributing to long-term neurological vulnerability and neurodegenerative disease risk.

To investigate the potential impact of lipidaemic and clinical factors on the development of proliferative vitreoretinopathy (PVR) following uncomplicated primary rhegmatogenous retinal detachment (RRD) surgery in nondiabetic individuals. This was a retrospective, single-center, case-control study of consecutive patients who underwent primary RRD surgery. The study group comprised 145 patients who developed PVR within 3y of follow-up, while the control group comprised 161 patients with RRD who did not develop PVR. Cox regression analysis was utilized to identify independent associations between various risk markers and the occurrence of PVR. The mean age of patients was 52.31y (SD=13.29), and 54.25% ( Apart from macular involvement and smoking, the lipidaemic factors ApoA1 and ApoE are risk factors of PVR after primary RRD surgery.

Early diagnosis of Alzheimer's disease (AD) and related dementias remains challenging because no single biomarker sufficiently captures the complex and multifactorial nature of the underlying pathology. In recent years, multimodal artificial intelligence (AI) models capable of integrating heterogeneous data sources-such as neuroimaging, fluid biomarkers, genetics, and cognitive assessments-have emerged as a promising strategy to improve early detection and risk stratification. We performed a PRISMA-guided systematic review (PROSPERO: CRD420251049848) of studies published from 2010 to 2025. We included 27 peer-reviewed studies applying AI/ML to ≥2 biomarker modalities for diagnostic classification or prognostic prediction (e.g., MCI-to-AD conversion), with an explicit emphasis on multimodal designs that incorporated at least one minimally invasive and/or widely deployable modality (e.g., cognitive tests, blood-based biomarkers, APOE/genetics, retinal imaging, or routine clinical features). Risk of bias was assessed using QUADAS-2. Across the 27 included studies, multimodal AI models generally outperformed the best unimodal baselines, particularly when combining complementary biological information (e.g., imaging with molecular or clinical features). Diagnostic tasks more often achieved high discrimination (frequently AUCs in the ~0.85-0.95 range under internal validation), whereas prognostic prediction-especially MCI-to-AD conversion-remained more challenging (typically ~0.75-0.85 AUC in the best-performing models). However, evidence for generalizability was limited, as external validation was uncommon and QUADAS-2 frequently highlighted concerns in the Index Test domain related to overfitting risk and incomplete validation. Overall, multimodal AI provides a more comprehensive representation of AD/MCI-related pathology than unimodal approaches and can improve early diagnostic classification and, to a lesser extent, prognostic prediction. However, translation to clinical practice is still constrained by limited external validation and heterogeneous reporting, which hamper generalizability and clinical trust. Future work should prioritize prospective multi-center studies, robust external validation, and transparent reporting (including interpretability analyses) to support real-world deployment. Show less

Rheumatoid arthritis (RA) is a chronic inflammatory joint disorder in which macrophages play crucial roles. Given macrophage heterogeneity, novel biomarkers are needed for timely diagnosis and severity assessment. This study aimed to identify macrophage-specific hub genes in RA and investigate their biological functions. Bulk and single-cell RNA-seq datasets were downloaded from the Gene Expression Omnibus (GEO). Differentially expressed genes (DEGs) in RA synovial macrophages were identified from the GSE97779 dataset using the Limma R package. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analyses were performed to determine the biological processes and pathways associated with the DEGs, followed by Gene Set Enrichment Analysis (GSEA) for further validation. Hub genes were identified using the STRING database and Cytoscape. Based on the single‑cell dataset GSE192504, cell clusters were annotated with Seurat to determine macrophage‑specific hub genes, whose associated biological processes were explored via gene set variation analysis (GSVA). Further sub‑clustering revealed distinct macrophage subtypes. Finally, immunofluorescence staining was performed to identify molecular markers of macrophage subtypes, while RT-qPCR and ELISA were used to validate the mRNA and protein expression of macrophage-specific hub genes in in vitro experiments. We identified 334 DEGs enriched in immune-related pathways. Ten hub genes ( Show less

In our previous study, we identified Niemann-Pick C1 like intracellular cholesterol transporter 1 (NPC1L1) as a key contributor in lipid oxidative stress during atherosclerosis (AS) progression. However, the regulation mode of its expression and the specific approaches by which it functions in lipid oxidative stress are still unclear. HUVECs and macrophages were treated with oxidized low-density lipoprotein (ox-LDL) to induce endothelial cell injury. First, the effects of the RNA binding proteins IGF2BP1 and poly (A) binding protein cytoplasmic 1 (PABPC1) on the stability of NPC1L1 mRNA was evaluated. The interaction between NPC1L1 and cytochrome P450 family 11 subfamily A member 1 (CYP11A1) was analyzed using Co-IP, and the co-localization of the two was detected using immunofluorescence. Combined with qPCR, Western blotting, CCK8, ferroptosis-related index and mitophagy-related index determination were performed to evaluate the expression of CYP11A1 in ox-LDL-treated HUVECs and its role of ferroptosis and mitophagy. Subsequently, pcDNA-NPC1L1 or CYP11A1 siRNA were individually or altogether transfected into ox-LDL-treated HUVECs to verify the involvement of CYP11A1 in NPC1L1-mediated ferroptosis and mitochondrial oxidative stress. Finally, ApoE-/- mice were fed with high-fat diet to establish an AS model in vivo and sh-NPC1L1 and/or Ad-CYP11A1 were injected via tail vein to verify the therapeutic effect of NPC1L1 knockdown on AS and reversal effect of CYP11A1. Either knockdown of IGF2BP1 or PABPC1 reduced NPC1L1 mRNA stability. Mechanistically, NPC1L1 interacted with CYP11A1 and promoted CYP11A1 protein expression. CYP11A1 was upregulated in ox-LDL-treated HUVECs and overexpression of CYP11A1 induced ferroptosis by activating excessive mitophagy, and knockdown of CYP11A1 reversed the promotion of NPC1L1 on mitophagy and ferroptosis in ox-LDL treated HUVECs. In vivo, injection of the sh-NPC1L1 lentiviral vector inhibited AS progression, while injection of the LV-CYP11A1 lentiviral vector attenuated the protective effect of sh-NPC1L1 on AS. PABPC1 and IGF2BP1 synergistically stabilized NPC1L1 mRNA, and NPC1L1 interacted with CYP11A1 to induce endothelial mitophagy and ferroptosis during AS. Show less

The rare APOE3-Christchurch (APOE3Ch) variant is linked to resistance against PSEN1 p.E280A-driven autosomal dominant Alzheimer's disease (AD). Recent studies in AD mouse models have demonstrated an effect of APOE3Ch in reducing tau pathology and tau propagation, yet its effects on amyloid pathology and related toxicity are not fully understood. While prior studies have reported reduced amyloid pathology with APOE3Ch, we extended this knowledge by investigating how astrocyte-specific expression of APOE3Ch impacts amyloid pathology and related responses in 5xFAD mice, an amyloid mouse model. Using adeno-associated virus (AAV)-mediated gene delivery, we overexpressed APOE3 or APOE3Ch in astrocytes of 5xFAD mice at the neonatal stage, then analyzed their effects during the advanced stage of amyloid pathology. Astrocytic APOE expression significantly reduced amyloid burden, neuritic dystrophy, and gliosis compared to GFP controls. Notably, astrocytic APOE3Ch expression, relative to APOE3, markedly lowered oligomeric Aβ levels and promoted the formation of more compact, fibrillar plaques, suggesting a shift toward a less toxic aggregation profile. Transcriptomic profiling of cortical tissue revealed broad downregulation of immune-related and proteostatic pathways. These findings indicate that astrocytic APOE3Ch sufficiently attenuates Aβ pathology and related toxicity, supporting its potential as a therapeutic modifier for AD. Show less

Atherosclerosis is a chronic inflammatory disease characterized by lipid-driven immune dysregulation. Argininosuccinate synthase 1 (ASS1) has been implicated in macrophage inflammation, yet its precise mechanistic role in foam cell-mediated vascular injury during atherosclerosis remains unclear. This study investigates whether ASS1 promotes disease progression via the NLRP3/IL-33/ST2 axis. An Ox-LDL treatment significantly upregulated ASS1 expression in U937-derived foam cells. ASS1 overexpression enhanced intracellular ROS production, NLRP3 inflammasome activation, STAT3 phosphorylation, and IL-33 secretion. These effects were reversed by ASS1 knockdown. Rescue experiments demonstrated that STAT3 is required for ASS1-mediated NLRP3 activation and IL-33 upregulation. ASS1 altered IL-33 receptor ST2 signaling by increasing the soluble decoy isoform (sST2) and decreasing the membrane-bound signaling isoform (ST2L). In co-culture, ASS1-overexpressing foam cells promoted HUVEC apoptosis (via mitochondrial pathway) and HAVSMC proliferation, migration, and dedifferentiation. NLRP3 overexpression alone mimicked the pro-inflammatory effects of ASS1 and reversed the anti-inflammatory effects of ASS1 knockdown. ASS1 drives atherosclerosis by activating the STAT3/NLRP3 inflammasome axis, shifting the IL-33/ST2 balance toward a pro-inflammatory state, and amplifying foam cell-mediated endothelial injury and smooth muscle cell dysfunction. Targeting ASS1 may offer a novel therapeutic strategy for inflammatory vascular disease. Show less

Social connectedness promotes healthy aging and is associated with lower risk for psychological disorders and cognitive decline. However, little is known about the mechanisms underlying these relationships, and whether different network features are associated with unique health benefits. We used comprehensive data from 386 community-dwelling older adults with and without cognitive impairment to test the relationship between psychological and cognitive function and their personal social networks. Data were collected using a multisite sampling strategy, and included detailed social network interviews and comprehensive measures of episodic memory, executive function, and language. Longitudinal effects were evaluated using a subsample at high-risk for decline, having either at least one copy of APOE ε4 or a current diagnosis of impairment ( The online version contains supplementary material available at 10.1038/s41598-026-44571-9.

Psoriasis vulgaris (PV) is a chronic inflammatory skin disease increasingly recognized as a systemic disorder with potential cognitive implications. Amyloid beta (Aβ) and apolipoprotein E (APOE) are key proteins involved in Alzheimer's disease (AD) and neurodegeneration. This study investigated the relationship between PV, cognitive function, and serum levels of Aβ and APOE4. This case-control study was conducted on 80 participants: 50 PV patients and 30 age- and sex-matched controls. Clinical assessments included Psoriasis Area and Severity Index (PASI). Depression severity was assessed with Beck Depression Inventory-II (BDI-II), while cognitive function was evaluated using Montreal Cognitive Assessment (MoCA). Serum APOE4 and Aβ levels were measured using ELISA. Patients with PV exhibited significantly higher levels of APOE4 (1125.5 ± 232.1 ng/ml vs. 821.8 ± 266 ng/ml, P<0.001) and Aβ (21.4 ± 2.2 ng/ml vs. 18.7 ± 1.4 ng/ml, P<0.001) compared to controls. ROC analysis identified APOE4 (AUC=0.80, P<0.001) and Aβ (AUC=0.86, P<0.001) as significant predictors of PV. MoCA scores were significantly lower in PV patients (median=22 vs. 28, P<0.001), particularly in those with severe disease. APOE4 and Aβ levels negatively correlated with cognitive function (r= -0.418, P=0.003), and (r= -0.399, P=0.004) respectively. PV is associated with elevated Aβ and APOE4 levels, potentially linking chronic inflammation to neurodegeneration. The observed cognitive dysfunction in PV individuals underscores the importance of integrating neurological assessments into routine clinical evaluations. Show less

This study evaluates the clinical validity of the Korean Computerized Cognitive Function Test (CFT-S) by comparing its domain-specific scores with those of the Seoul Neuropsychological Screening Battery-II (SNSB-II) in patients with Mild Cognitive Impairment (MCI) or Alzheimer's Disease (AD). A total of 300 participants (MCI: n = 163; AD: n = 137) from Severance Hospital completed both CFT-S and SNSB-II assessments within a two-week interval, along with brain MRI and APOE genotyping. Pearson correlations and multiple regression analyses examined relationships between cognitive scores and biomarker variables. Receiver operating characteristic curves assessed diagnostic accuracy. Bland-Altman plots evaluated agreement across five shared cognitive domains. CFT-S index scores showed significant positive correlations with SNSB-II in attention, language, visuospatial, and executive domains (r = 0.59-0.71, p < 0.001). The memory domain showed a lower correlation in AD patients (r = 0.28), reflecting limitations under severe impairment. Hippocampal volume was positively associated with MMSE (r = 0.54), CFT-S memory (r = 0.50), and SNSB memory scores (r = 0.52). Education correlated with MMSE (r = 0.32) but not with CFT-S or SNSB, suggesting minimal education bias. APOE-ε4 carriers had smaller hippocampal volumes, higher FBB-PET BAPL scores, and poorer cognitive outcomes. The Bland-Altman plots demonstrated acceptable agreement at the group level between CFT-S and SNSB-II across all cognitive domains, with small mean biases and symmetric distributions despite relatively wide limits of agreement. CFT-S index scores and Bland-Altman plot analysis demonstrated validity relative to SNSB-II, with significant associations to hippocampal atrophy and genetic risk factors. The findings support CFT-S as a viable and efficient cognitive assessment tool for diagnosing MCI and AD. Show less

According to existing research findings, dihydroartemisinin effectively regulates bone metabolism balance, while ferroptosis is closely related to the occurrence of steroid-induced osteonecrosis of the femoral head. As the exact biological mechanism among the three is still unclear, Mendelian randomization, computer-aided drug design, and transcriptomics sequencing were used to explore the specific mechanism of action. The study validated the specific signaling pathways through which dihydroartemisinin may treat steroid-induced osteonecrosis of the femoral head using animal experiments and transcriptomics sequencing. Data were obtained from public databases for Mendelian randomization analysis, and a two-sample Mendelian randomization was used to determine the intermediary role of core pathway-related targets. Computer-aided drug design was employed to assess the binding affinity between dihydroartemisinin and core targets. Transcriptome sequencing determined that dihydroartemisinin may treat steroid-induced osteonecrosis of the femoral head by regulating ferroptosis. We obtained 564 ferroptosis-related targets that met the analysis criteria and 1812 plasma proteins from the UK Biobank, and analyzed finngen_R11_OSTEON_DRUGS in the Finnish database as outcome. The results showed that there were two quantitative trait loci that had a causal relationship with ferroptosis targets. There were 110 protein quantitative trait loci causally associated with plasma proteins from the UK Biobank, and none of these loci had an inverse causal relationship with SONFH. Through mediation analysis, 7 mediating pathways were identified, yielding eight targets including ZP3, CCL17, APOE, C7ORF50, SPINK4, SPINK2, FTMT, and PRDX6. Computer-aided drug design revealed that CCL17 and PRDX6 exhibited the best docking effects. The study determined that CCL17 and PRDX6 have a significant causal relationship with SONFH. It also clarified the specific mechanism by which DHA may regulate ferroptosis to treat SONFH, which will provide a reference for the discussion of the prevention and treatment mechanisms of SONFH.

Visceral fat (VF), particularly epicardial adipose tissue (EAT), plays a crucial role in the development of coronary artery disease (CAD). Cathelicidin (LL37) is an antimicrobial peptide involved in innate immunity and has been implicated in inflammatory processes. However, the relationship between VF accumulation, cathelicidin, and atherosclerosis remains unclear. Seventy-eight subjects without CAD were enrolled and classified by obesity type: normal-weight (normal; n=20), subcutaneous fat (SF; n=19), and VF (n=39). Plasma LL37 concentrations were compared across groups. LL37 expression in EAT was assessed in 9 patients undergoing open-heart surgery, stratified by CAD status. In animal experiments, angiotensin II-infused wild-type and Apoe LL37 is associated with VF accumulation and CAD.

Increasing evidence indicates that modulating pyroptosis in endothelial cells (ECs) can alleviate atherosclerosis (AS) progression; however, despite reports that nucleolin (NCL) regulates vascular smooth muscle cell proliferation in AS, the potential mechanism by which cell surface NCL mediates pyroptosis in ECs during AS remains poorly understood.

Early and accurate detection of Alzheimer's disease (AD) is essential for timely intervention and development of disease-modifying treatments. The DZNE-Longitudinal Cognitive Impairment and Dementia Study (DELCODE) provides a deeply phenotyped cohort covering preclinical and early clinical stages, including subjective cognitive decline (SCD) and mild cognitive impairment (MCI). Astrocyte reactivity and its biomarkers, particularly glial fibrillary acidic protein (GFAP), have gained increasing attention in AD research; however, the relationship between GFAP and amyloid in early disease, as well as its potential prognostic value beyond its association with amyloid status, remains insufficiently understood. To evaluate the performance of CSF and plasma GFAP across early disease stages, compare these measures according to amyloid status, and assess the prognostic value of GFAP for clinical progression across diagnostic stages during longitudinal follow-up. This study used data from the multicenter DELCODE cohort in Germany, including participants with available plasma and/or CSF samples and standardized clinical, cognitive, imaging, and biomarker assessments. GFAP concentrations in plasma and CSF were quantified using validated immunoassay platforms. Standard CSF AD biomarkers and ApoE genotype were measured using established assays. Amyloid status was defined by the CSF Aβ42/40 ratio. Longitudinal follow-up occurred annually for up to ∼10 years, with clinical conversion determined according to NIA-AA criteria. Plasma and CSF GFAP increased across the AD continuum, with higher levels in MCI and AD (p < 0.001). Plasma GFAP showed a stronger association with amyloid status than CSF GFAP across all groups. In MCI, plasma GFAP combined with age and ApoE4 yielded an AUC of 0.87. Elevated plasma GFAP predicted increased risk of conversion to MCI (HR = 2.19, p < 0.001; adjusted HR = 1.70, p = 0.0056) and AD dementia (HR = 3.5; adjusted HR = 2.49 both p < 0.001). Plasma GFAP is a sensitive, minimally invasive biomarker with diagnostic relevance for amyloid detection and prognostic relevance for clinical progression in early AD. Show less

We evaluated the accuracy of standard machine learning (ML) algorithms in predicting 1-year cognitive decline in Alzheimer's disease patients with mild cognitive impairment (ADMCI) using resting-state electroencephalographic (rsEEG) biomarkers enriched with APOE genotype, sex, age, and educational attainment data. The study analyzed datasets from 63 ADMCI patients obtained from an international archive. The ML algorithms included Simple Logistic Regression, Model Trees, Logistic Regression, K-nearest neighbor, and Support Vector Machine. Input features comprised lobar rsEEG source activities across delta (<4 Hz) to alpha (≈10-12 Hz) bands, cerebrospinal fluid (CSF Aβ1-42/p-tau), and structural magnetic resonance imaging (sMRI) biomarkers. Cognitive decline was assessed over a 1-year follow-up ("stable" vs. "decliner") based on Mini-Mental State Examination (MMSE) scores. The four independent ML algorithms accurately predicted changes in the MMSE score over a 1-year follow-up, with accuracies of 77-78% in ADMCI participants aged ≥ 70 years and 74-77% in those aged < 70 years. These findings suggest that rsEEG biomarkers in ADMCI patients may not only reveal underlying pathophysiological mechanisms affecting cortical arousal and vigilance but also hold predictive value for cognitive outcomes.

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

Alzheimer's disease (AD) is the most prevalent cause of dementia and can be conceptualized as a tauopathy initiated by the accumulation of amyloid-β (Aβ) in the brain. The clinical introduction of anti-Aβ antibody therapies has marked the beginning of a new era in disease-modifying treatment for dementia. While the deleterious effects of Aβ on postsynaptic spines and axonal microtubules have been increasingly clarified, recent studies have shifted attention beyond extracellular Aβ deposition as senile plaques to the pathogenic significance of intracellular Aβ. In particular, accumulating evidence highlights lysosomes as critical sites of intracellular Aβ toxicity. Interactions between Aβ and gangliosides, v-ATPase-dependent lysosomal acidification, and lysosomal membrane integrity are the key determinants of disease progression. In parallel, additional molecular players, including components of the complement cascade and asparaginyl endopeptidase, have been implicated in linking Aβ pathology to tau dysregulation and neurodegeneration. As therapeutic strategies targeting Aβ enter clinical practice, these emerging pathways represent promising targets for the next generation of AD treatment. Here, we summarize current insights and ongoing therapeutic developments centered on these mechanisms. Show less

To address this gap, the present study applies a framework that integrates locus-level genetic correlation (rg) with genetically regulated gene expression to clarify the molecular factors contributing to the inverse epidemiological patterns observed between the two diseases. We used the largest available genome-wide association studies (GWAS) (Nmax = 448,150) to quantify local genetic correlations between AD and several age-associated cancers, including breast, prostate, lung, colorectal, melanoma, basal cell carcinoma, bladder, and endometrial cancer. Eight genomic regions showed significant negative local rg, at the 19q13.31-19q13.32 locus demonstrating strong negative correlations across multiple cancers, including breast, prostate, lung, melanoma, and endometrial cancer. To evaluate the contribution of genetically regulated gene expression, we conducted transcriptome-wide association studies (TWAS) using precomputed gene expression weights from cancer tissues (The Cancer Genome Atlas-TCGA), disease-agnostic tissues (Genotype-Tissue Expression-GTEx), and brain tissue (dorsolateral prefrontal cortex-DLPFC). For each AD-cancer pair, we prioritized genes that were nominally significant in both traits ( Show less

Atherosclerosis (AS), a chronic cardiovascular disease, originates from endothelial dysfunction, a process closely linked to cellular energy metabolism. While rosmarinic acid (RA) exhibits protective cardiovascular effects, its precise mechanism against AS remains undefined. This study demonstrates that RA alleviates AS in ApoE Show less

Periodontitis is implicated in a range of systemic conditions, including cardiovascular disease, diabetes, and respiratory disorders. Emerging evidence suggests a link between periodontal infection, inflammation, and the neurodegenerative process of Alzheimer's disease (AD). This paper aimed to systematically review observational studies examining the association of periodontal pathogens and their inflammatory products with AD neurodegeneration. The review was registered in the International Prospective Register of Systematic Reviews (PROSPERO - No. CRD42020150043). Methods followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. An electronic search (PubMed/Medical Literature Analysis and Retrieval System Online (MEDLINE), Web of Science, Scopus, Cochrane Library, grey literature) was conducted until September 2025 with no language or date restrictions. Two independent reviewers screened and extracted data. The risk of bias was assessed via the Risk Of Bias In Non-randomized Studies - of Exposures (ROBINS‑E) tool. Of 1,421 identified citations, eight studies met the inclusion criteria. Participant numbers ranged from 349 to 2,191, and ages ranged from 40 to 90 years old. Meta‑analysis was not feasible due to methodological heterogeneity. Risk of bias was moderate in five studies and serious in three. Findings indicated that higher serum IgG antibodies to periodontal pathogens and elevated inflammatory mediators, notably tumor necrosis factor-alpha (TNF‑α), correlated with greater cognitive decline and markers of AD neurodegeneration, including MRI outcomes and APOE ε4 status. In conclusion, the current body of evidence suggests a potential association between periodontitis‑related inflammatory mediators, particularly TNF‑α, and elevated antibody responses to periodontal pathogens with AD progression. However, causality remains unestablished. Future prospective cohort and interventional studies are warranted to clarify the role of periodontal infection and inflammation in AD and to guide clinical strategies that may improve outcomes in AD populations.
