This challenges the traditional view that AD-related inflammation can be broadly suppressed therapeutically. We review evidence showing that neuroinflammation in AD is stage-dependent, cell-state-specific, spatially organized, and functionally complex. Microglia and astrocytes can aid in plaque containment, debris clearance, synaptic balance, metabolic adaptation, and tissue repair, but may also exacerbate injury through type-I interferon, inflammasome, complement, tumor necrosis factor, and lipid pathways. Many failed anti-inflammatory trials likely stem from mismatches in targets, timing, spatial considerations, pathway redundancy, and biomarker selection, rather than invalidating neuroinflammation as a therapeutic target. Recent single-cell and spatial transcriptomic, proteomic, metabolomic, and network-medicine studies offer a framework for precision intervention by identifying inflammatory endotypes, anatomical niches, and pathway modules. We propose the Stage-State-Space Neuroimmune Reprogramming Model (S3-NRM), aligning AD immunotherapy with disease stage, glial/endotype state, and spatial inflammatory niche, guided by fluid, imaging, and omics biomarkers.

Although both agents have demonstrated therapeutic potential, their post-marketing adverse event reporting profiles remain insufficiently characterized and compared in spontaneous reporting systems. This study aimed to systematically compare adverse event signals associated with these two drugs using the FDA Adverse Event Reporting System database, with sex-stratified and sensitivity analyses performed to support the main findings. FAERS reports up to the fourth quarter of 2025 were retrospectively analyzed. Reports in which lecanemab or donanemab was recorded as the primary suspect drug were included. AEs were classified by system organ classes (SOCs) and preferred terms (PTs) according to the Medical Dictionary for Regulatory Activities (MedDRA). Signal detection was performed using four algorithms: reporting odds ratio (ROR), proportional reporting ratio (PRR), Bayesian confidence propagation neural network (BCPNN), and multi-item gamma Poisson shrinker (MGPS). Sex-stratified analysis, sensitivity analysis after excluding reports involving concomitant medications, and time-to-onset (TTO) analysis based on the Weibull shape parameter model were also conducted. False discovery rate (FDR) correction was applied to analyses involving multiple P values. A total of 3,640 AE reports were identified, including 2,602 for lecanemab and 1,038 for donanemab. Nervous system disorders was the most frequently reported SOC and the only SOC meeting the positivity criteria across all four algorithms for both drugs. At the PT level, the frequently reported events for both drugs were mainly concentrated in amyloid-related imaging abnormality (ARIA)-related events, including ARIA with oedema/effusion (ARIA-E) and ARIA with microhaemorrhages/haemosiderin deposition (ARIA-H), headache, and infusion-related reactions. The strongest disproportionality reporting signals were mainly observed for ARIA-related preferred terms and cerebral microhaemorrhage. In separate FAERS-based disproportionality analyses, lecanemab showed stronger disproportionality reporting signals for ARIA-H, whereas donanemab showed stronger disproportionality reporting signals for ARIA-E. In addition, drug-specific PT signal distributions differed between the two agents. Several potential novel PT signals were also identified. Sex-stratified analysis suggested differences in the distribution of certain PT signals between female and male reports. Sensitivity analysis supported the stability of most core signals. The median TTO was 46 days for lecanemab and 31 days for donanemab, and Weibull analysis suggested different temporal patterns of AE occurrence. Using four signal detection algorithms, this study compared real-world adverse event reporting profiles associated with lecanemab and donanemab. The two drugs showed both shared and distinct adverse event reporting profiles, particularly in ARIA subtype-related disproportionality signals, drug-specific PT signals, potential novel reporting signals, sex-stratified reporting patterns, and TTO characteristics. These findings provide pharmacovigilance evidence for targeted safety monitoring and hypothesis generation, but should not be interpreted as causal associations or true incidence estimates."},{"quadrant":"Run1_Eval1_synthesis","attempt":1,"quote":"This shows the most accurate technique for predicting Alzheimer's Disease (AD) using the prognostic IDRODN model.","status":"PASS","error":"","abstract_text":"ID: 42431913\nTitle: Novel approach to early prediction of alzheimer's disease progression using integrated deep regulatory genetic neural network and optimized deep belief networks.\nAbstract: To enhance the prediction progression of Alzheimer's Disease is very excavating process.

Here, we applied DNA-encoded library (DEL) screening of approximately 3.6 billion compounds to identify small molecule binders of LILRB4. Biophysical validation identified APX1 as a direct LILRB4 ligand with submicromolar affinity, which was further confirmed by cellular thermal shift assay (CETSA). Docking-guided mutagenesis studies defined a discrete ligand-binding interface involving key hotspot residues required for stable target engagement. Functionally, APX1 disrupted the LILRB4-ApoE interaction in orthogonal ELISA and biolayer interferometry assays. In human iPSC-derived microglia, APX1 suppressed SHP1/2 phosphorylation, attenuated NF-κB activation and IL-1β secretion, and restored Aβ42 uptake under ApoE-driven inflammatory conditions. APX1 further demonstrated favorable in vitro developability, metabolic stability, and CNS exposure properties. In the 5xFAD mouse model of AD, oral administration of APX1 improved cognitive performance, reduced cortical and hippocampal Aβ42 burden, suppressed neuroinflammatory cytokines, and decreased activated microglial populations.

This pathogenesis is characterized by amyloid-β (Aβ) aggregation, tau hyperphosphorylation, persistent neuroinflammation, oxidative stress, and synaptic dysfunction. Conventional single-target interventions have consistently failed against this complex interplay of molecular events, thereby highlighting the need for multitarget, systems pharmacology approaches capable of simultaneously modulating convergent pathways. Apremilast (APR), an FDA-approved, orally bioavailable phosphodiesterase-4 (PDE4) inhibitor, has recently emerged as a favorable drug repurposing candidate capable of elevating intracellular cAMP and triggering a cascade of neuroprotective mechanisms. Preclinical investigations from Aβ-challenged neuronal cultures to high-fat diet/streptozotocin-induced rodent models of AD demonstrate that APR attenuates Aβ-induced cytotoxicity, improves cognitive performance, and preserves neuronal and synaptic integrity. Mechanistically, APR mitigates NF-κB-mediated neuroinflammation through IκBα stabilization, thereby reducing the release of proinflammatory cytokines such as TNF-α and IL-6; activates the Nrf2/HO-1 antioxidant defense pathway, and, via cAMP-dependent PI3K/Akt signaling, inhibits GSK-3β to prevent tau hyperphosphorylation, synaptic loss, and neuronal degeneration. This review synthesizes current mechanistic evidence supporting apremilast as a potential multitarget repurposing candidate in AD, thereby addressing key knowledge gaps in the current literature. All supporting evidence was compiled from peer-reviewed sources indexed in PubMed, Web of Science, and Scopus.

Repurposing drugs to target these mechanisms offers a promising approach to reduce the costs and duration of drug development. Genetic studies underscore the critical role of microglial clearance of amyloid-beta (Aβ) in AD pathogenesis. Specifically, soluble ST2 (sST2)-one of the two major isoforms of the ST2 protein encoded by the IL1RL1 (interleukin-1 receptor-like 1) gene-acts as a decoy receptor isoform that interferes with IL-33/ST2 signaling and has been identified as a disease-modifying factor that impairs microglial Aβ clearance functions. In this study, we investigated drug repurposing opportunities to modulate sST2 levels and alleviate AD pathologies. Unbiased screening of commonly used medications in AD patients, followed by validation in model systems, identified trazodone-an antidepressant used to treat major depressive disorder-as a leading negative regulator of sST2. Trazodone primarily suppresses sST2 expression through its antagonistic effects on adrenergic signaling. In the APP/PS1 transgenic mouse model of AD, trazodone treatment enhanced microglial interaction with Aβ and alleviated Aβ pathology. Furthermore, trazodone reduced neurodegeneration and rescued synaptic deficits in APP/PS1 mice. Comprehensive molecular profiling of APP/PS1 mouse brains showed that trazodone restored the expression of synaptic proteins critical for synaptic integrity and plasticity. Overall, these findings demonstrate that trazodone is a promising repurposing candidate for AD that targets underlying immune dysfunctions and synaptic impairment."},{"quadrant":"Run1_Eval1_synthesis","attempt":1,"quote":"Our findings establish EphB1-mediated facilitation of BBB traversal as a promising strategy for enhancing nanotherapeutic delivery to the brain, offering a potent approach to address the complex pathology of AD.","status":"PASS","error":"","abstract_text":"ID: 42406553\nTitle: EphB1-Mediated Transient Blood-Brain Barrier Opening Facilitates a Ferritin-Based Nanotherapeutic for Alzheimer's Disease.\nAbstract: The treatment of Alzheimer's disease (AD) is severely hampered by the blood-brain barrier (BBB), which limits the delivery of therapeutic agents like donepezil (DPZ), an acetylcholinesterase inhibitor. While DPZ has multi-faceted benefits, its clinical efficacy is constrained by poor BBB penetration, requiring high doses that lead to significant side effects. To overcome this, we developed a brain-targeted nanotherapeutic utilizing apoferritin (AFn) nanoparticles loaded with DPZ (AFn-DPZ). We demonstrate that this platform, by binding to the EphB1 receptor on the blood-brain barrier, enables transient and reversible opening of the blood-brain barrier, thereby facilitating efficient and targeted drug delivery. Following intravenous administration in an AD mouse model, AFn-DPZ exhibited enhanced brain accumulation and sustained release of DPZ. This targeted delivery inhibited acetylcholinesterase activity, reduced amyloid plaque burden, alleviated neuroinflammation, attenuated oxidative damage, restored mitochondrial function, and upregulated the expression of brain-derived neurotrophic factor (BDNF). Consequently, AFn-DPZ treatment significantly improved cognitive performance compared to free DPZ.

However, the application of natural exosomes is constrained by their poor targeting ability. Herein, we report a novel drug delivery system (P2-Exo-Cur) constructed by engineering exosomes to display the P2 peptide on their surface, thereby enabling targeted delivery of curcumin to microglia. Our results revealed that P2-Exo-Cur possesses a nanoscale membrane structure and can efficiently deliver curcumin to microglia both in vitro and in vivo. This technology provides a microglia-targeted delivery approach for anti-inflammatory agents such as curcumin, while overcoming the undesirable off-target effects that limit their efficacy. Furthermore, treatment of lipopolysaccharide (LPS)-induced inflammatory BV2 cell models with P2-Exo-Cur significantly suppressed the polarization of BV2 cells toward the M1 phenotype, as well as the secretion of pro-inflammatory cytokines. Finally, we also validated the excellent therapeutic potential of this technology in the 5xFAD mouse model. In conclusion, in this study, we for the first time constructed engineered exosomes that can specifically bind to the NCAM protein on microglia to achieve precise delivery of curcumin by expressing the P2 peptide on their surface, exerting beneficial effects in AD treatment without causing significant adverse effects.

Although deep learning has achieved promising performance in AD diagnosis, existing multimodal models often operate as \"black boxes,\" lacking the transparency required for clinical practice and failing to explicitly model deep interactions between imaging and clinical features. To address these limitations, this study proposes an interpretable multimodal framework, namely the Compact Biomarker Kolmogorov-Arnold Network (CBKAN). Specifically, we introduce EHCTNet with disease-specific attention to extract features from 3D MRI data, and innovatively constrain the encoder to output a set of compact biomarkers instead of traditional high-dimensional abstract vectors, mimicking the diagnostic logic of clinicians (e.g., judging brain atrophy). In addition, a hybrid feature Transformer is used to fuse these imaging biomarkers with clinical and genetic data, explicitly capturing complementary relationships across modalities. Finally, the Kolmogorov-Arnold Network (KAN) is adopted as the classifier to effectively model the highly nonlinear characteristics of AD progression.

Genetic, single-cell, and spatial studies have shown that Alzheimer 's-associated microglia occupy diverse disease-linked states shaped by amyloid plaques, tau pathology, lipid stress, complement activation, astrocyte signaling, aging, and immune genetic risk. Among the regulatory nodes controlling these states, SPI1, which encodes the myeloid transcription factor PU.1, has emerged as a key determinant of microglial identity and disease responsiveness. Human genetic studies suggest that reduced SPI1 expression may be protective, whereas experimental data indicate that excessive PU.1 suppression can impair essential microglial functions. This review examines the emerging concept that partial, plaque-associated reduction in PU.1 may enable a distinct lymphoid-like immunoregulatory microglial program marked by CD28 expression. Recent evidence suggests that PU.1-low CD28-positive microglia may restrain neuroinflammation and amyloid pathology, raising the possibility that Alzheimer's plaques induce not only inflammatory and phagocytic microglial responses, but also endogenous suppressive programs that limit tissue damage. We discuss this proposed PU.1/CD28 regulatory axis in relation to disease-associated microglia, TREM2-APOE signaling, complement-mediated synapse loss, antigen-presentation pathways, plaque-niche biology, and therapeutic microglial reprogramming. We also highlight major unresolved questions, including whether PU.1-low CD28-positive microglia are present and functional in human Alzheimer's disease, whether they are specific to amyloid-rich niches or extend to tau and mixed pathologies, and how such states could be safely manipulated without disrupting essential immune surveillance. We propose that lymphoid-like suppressive microglia represent a promising but still unproven framework for understanding protective neuroimmune regulation in Alzheimer's disease and for developing state-specific microglial therapies."},{"quadrant":"Run1_Eval1_synthesis","attempt":1,"quote":"The strongest disproportionality reporting signals were mainly observed for ARIA-related preferred terms and cerebral microhaemorrhage.","status":"PASS","error":"","abstract_text":"ID: 42440686\nTitle: Comparison of safety of lecanemab and donanemab: a real-world disproportionality analysis using the FDA adverse event reporting system.\nAbstract: Lecanemab and donanemab are anti-amyloid-β (Aβ) monoclonal antibodies recently approved for the treatment of Alzheimer's disease (AD).

However, the timing of these alterations in vivo with respect to disease progression is unclear. Here, in longitudinal recordings from APP/PS1/PV-cre (AD mice) from 3-6 months, we found reduced sleep slow-wave power (0.5-4 Hz) in hippocampus and medial prefrontal cortex in AD mice as young as 3 months old, compared to non-AD (PV-cre) mice, well before overt pathology. This finding was primarily due to reductions in the NREM delta range (1.5-4 Hz), a hallmark of restorative functions of sleep. In contrast, beta (15-30 Hz) power linked to insomnia was significantly higher across all sleep-wake states. Loss of deep NREM sleep was not compensated by an increase in NREM sleep time, instead NREM sleep during the dark (active) phase was slightly but significantly lower in AD mice. 40-Hz auditory steady-state responses and associated evoked calcium responses of hippocampal PV neurons recorded using fiber photometry were also impaired by 3 months old.

However, whether Fc-mediated effector function is absolutely required for efficacy is not completely understood. This is important for optimizing therapeutic efficacy and mitigating side effects such as amyloid-related imaging abnormalities (ARIA). Antibodies lacking Fc effector function, like single-domain antibodies (nanobodies), offer a unique tool to dissect these mechanisms, as their small size facilitates blood-brain barrier (BBB) penetration and allows Fc-mediated functions to be studied independently. We immunized a llama with Aβ aggregates and constructed a phage display library to screen for aggregate-specific nanobodies. Lead candidates were characterized by epitope mapping and binding affinity to amyloid plaques in both murine and human AD brain tissues. We further assessed their BBB permeability and evaluated their efficacy in clearing pre-existing plaques in amyloid precursor protein (APP)/presenilin 1 (PS1) mice. We identified two lead nanobodies, 3A11 and 2D10, that bind distinct epitopes and specifically bind Aβ plaques in murine and human AD brain tissues. Following systemic administration, the monovalent, unmodified (Fc-less) 2D10 nanobody, but not 3A11, successfully crossed the BBB and engaged amyloid plaques in APP/PS1 mice. However, despite robust target engagement, the Fc-less 2D10 failed to recruit microglia or reduce plaque burden. In contrast, an engineered 2D10-Fc fusion antibody potently cleared amyloid plaques, achieving a reduction in pathology comparable to aducanumab treatment. This efficacy was directly correlated with Fc-mediated microglial recruitment and activation, demonstrating that the Fc domain is essential for phagocytic plaque removal. Our findings demonstrate that Fc effector function is indispensable for microglial-mediated amyloid clearance in vivo. By clarifying this fundamental mechanism, this study provides a framework for the rational design of next-generation immunotherapies. Furthermore, 2D10-Fc represents a promising therapeutic candidate, combining the high-affinity targeting of nanobodies with the effector power necessary for robust plaque clearance."},{"quadrant":"Run1_Eval1_synthesis","attempt":1,"quote":"Integrating preclinical and clinical evidence, we propose an \"APOE4-associated peripheral-central immune infiltration cascade\" as a unifying framework for understanding systemic AD pathogenesis.","status":"PASS","error":"","abstract_text":"ID: 42435996\nTitle: Targeting the APOE4-driven peripheral-central immune axis: A new frontier for Alzheimer's disease therapy.\nAbstract: Alzheimer's disease (AD) is a progressive neurodegenerative disorder and a growing global health challenge.

We discuss APOE expression in CNS and peripheral immune cells, highlighting APOE4-associated alterations in monocyte/macrophage polarization, T cell subsets via IL-7/IL-7R downregulation, and gut microbiota composition. We delineate mechanisms by which APOE4 is associated with blood-brain barrier compromise, may promote conditions for immune cell trafficking, and contributes to neuroinflammation.

This pathogenesis is characterized by amyloid-β (Aβ) aggregation, tau hyperphosphorylation, persistent neuroinflammation, oxidative stress, and synaptic dysfunction. Conventional single-target interventions have consistently failed against this complex interplay of molecular events, thereby highlighting the need for multitarget, systems pharmacology approaches capable of simultaneously modulating convergent pathways. Apremilast (APR), an FDA-approved, orally bioavailable phosphodiesterase-4 (PDE4) inhibitor, has recently emerged as a favorable drug repurposing candidate capable of elevating intracellular cAMP and triggering a cascade of neuroprotective mechanisms. Preclinical investigations from Aβ-challenged neuronal cultures to high-fat diet/streptozotocin-induced rodent models of AD demonstrate that APR attenuates Aβ-induced cytotoxicity, improves cognitive performance, and preserves neuronal and synaptic integrity. Mechanistically, APR mitigates NF-κB-mediated neuroinflammation through IκBα stabilization, thereby reducing the release of proinflammatory cytokines such as TNF-α and IL-6; activates the Nrf2/HO-1 antioxidant defense pathway, and, via cAMP-dependent PI3K/Akt signaling, inhibits GSK-3β to prevent tau hyperphosphorylation, synaptic loss, and neuronal degeneration.

Repurposing drugs to target these mechanisms offers a promising approach to reduce the costs and duration of drug development. Genetic studies underscore the critical role of microglial clearance of amyloid-beta (Aβ) in AD pathogenesis. Specifically, soluble ST2 (sST2)-one of the two major isoforms of the ST2 protein encoded by the IL1RL1 (interleukin-1 receptor-like 1) gene-acts as a decoy receptor isoform that interferes with IL-33/ST2 signaling and has been identified as a disease-modifying factor that impairs microglial Aβ clearance functions. In this study, we investigated drug repurposing opportunities to modulate sST2 levels and alleviate AD pathologies. Unbiased screening of commonly used medications in AD patients, followed by validation in model systems, identified trazodone-an antidepressant used to treat major depressive disorder-as a leading negative regulator of sST2. Trazodone primarily suppresses sST2 expression through its antagonistic effects on adrenergic signaling. In the APP/PS1 transgenic mouse model of AD, trazodone treatment enhanced microglial interaction with Aβ and alleviated Aβ pathology. Furthermore, trazodone reduced neurodegeneration and rescued synaptic deficits in APP/PS1 mice.

However, the timing of these alterations in vivo with respect to disease progression is unclear. Here, in longitudinal recordings from APP/PS1/PV-cre (AD mice) from 3-6 months, we found reduced sleep slow-wave power (0.5-4 Hz) in hippocampus and medial prefrontal cortex in AD mice as young as 3 months old, compared to non-AD (PV-cre) mice, well before overt pathology. This finding was primarily due to reductions in the NREM delta range (1.5-4 Hz), a hallmark of restorative functions of sleep. In contrast, beta (15-30 Hz) power linked to insomnia was significantly higher across all sleep-wake states. Loss of deep NREM sleep was not compensated by an increase in NREM sleep time, instead NREM sleep during the dark (active) phase was slightly but significantly lower in AD mice. 40-Hz auditory steady-state responses and associated evoked calcium responses of hippocampal PV neurons recorded using fiber photometry were also impaired by 3 months old. However, Y-maze performance in 3- and 6-month-old AD mice was not significantly different from non-AD mice.

There is mounting evidence suggesting that glymphatic dysfunction is an important cause of neurodegenerative diseases, characterized by failure of cerebrospinal fluid-interstitial fluid (CSF-ISF) exchange due to abnormal clearance. Mechanistically, this dysfunction is affected by aging, astroglial aquaporin-4 (AQP4) depolarization, vascular impairment, sleep abnormalities, oxidative damage, and neuroinflammation. Additionally, aberrant glymphatic flow acts as a crucial link between peripheral and central pathologies, amplifying neurodegeneration via altered solute transport and inflammation signaling. Glymphatic dysfunction has been found to be involved in diseases such as AD, PD and HD, thus indicating the widespread significance of glymphatic pathology. Therapeutically, targeting glymphatic function through modulation of AQP4 polarization, improving sleep-dependent clearance, and decreasing oxidative and inflammatory mechanisms may provide promising strategy for disease modification.

However, whether Fc-mediated effector function is absolutely required for efficacy is not completely understood. This is important for optimizing therapeutic efficacy and mitigating side effects such as amyloid-related imaging abnormalities (ARIA). Antibodies lacking Fc effector function, like single-domain antibodies (nanobodies), offer a unique tool to dissect these mechanisms, as their small size facilitates blood-brain barrier (BBB) penetration and allows Fc-mediated functions to be studied independently. We immunized a llama with Aβ aggregates and constructed a phage display library to screen for aggregate-specific nanobodies. Lead candidates were characterized by epitope mapping and binding affinity to amyloid plaques in both murine and human AD brain tissues. We further assessed their BBB permeability and evaluated their efficacy in clearing pre-existing plaques in amyloid precursor protein (APP)/presenilin 1 (PS1) mice. We identified two lead nanobodies, 3A11 and 2D10, that bind distinct epitopes and specifically bind Aβ plaques in murine and human AD brain tissues. Following systemic administration, the monovalent, unmodified (Fc-less) 2D10 nanobody, but not 3A11, successfully crossed the BBB and engaged amyloid plaques in APP/PS1 mice. However, despite robust target engagement, the Fc-less 2D10 failed to recruit microglia or reduce plaque burden. In contrast, an engineered 2D10-Fc fusion antibody potently cleared amyloid plaques, achieving a reduction in pathology comparable to aducanumab treatment. This efficacy was directly correlated with Fc-mediated microglial recruitment and activation, demonstrating that the Fc domain is essential for phagocytic plaque removal. Our findings demonstrate that Fc effector function is indispensable for microglial-mediated amyloid clearance in vivo. By clarifying this fundamental mechanism, this study provides a framework for the rational design of next-generation immunotherapies. Furthermore, 2D10-Fc represents a promising therapeutic candidate, combining the high-affinity targeting of nanobodies with the effector power necessary for robust plaque clearance."},{"quadrant":"Run1_Eval1_synthesis","attempt":2,"quote":"Integrating preclinical and clinical evidence, we propose an \"APOE4-associated peripheral-central immune infiltration cascade\" as a unifying framework for understanding systemic AD pathogenesis.","status":"PASS","error":"","abstract_text":"ID: 42435996\nTitle: Targeting the APOE4-driven peripheral-central immune axis: A new frontier for Alzheimer's disease therapy.\nAbstract: Alzheimer's disease (AD) is a progressive neurodegenerative disorder and a growing global health challenge.

Emerging evidence implicates neuroimmune dysfunction as a central driver of AD pathology, with the \"peripheral-central immune axis\" emerging as a critical node. The APOE4 allele, the strongest genetic risk factor for sporadic AD, plays a pivotal role in both central nervous system (CNS) lipid metabolism and peripheral immune homeostasis. This review synthesizes the association between APOE4 and peripheral immune dysregulation and its impact on neurodegeneration. We discuss APOE expression in CNS and peripheral immune cells, highlighting APOE4-associated alterations in monocyte/macrophage polarization, T cell subsets via IL-7/IL-7R downregulation, and gut microbiota composition. We delineate mechanisms by which APOE4 is associated with blood-brain barrier compromise, may promote conditions for immune cell trafficking, and contributes to neuroinflammation.

We conducted a prospective cohort study using UK Biobank participants free of dementia at baseline. Antidepressant use was self-reported at baseline (2006-2010). Incident dementia was identified through linked electronic health records until December 19, 2022.

While DPZ has multi-faceted benefits, its clinical efficacy is constrained by poor BBB penetration, requiring high doses that lead to significant side effects. To overcome this, we developed a brain-targeted nanotherapeutic utilizing apoferritin (AFn) nanoparticles loaded with DPZ (AFn-DPZ). We demonstrate that this platform, by binding to the EphB1 receptor on the blood-brain barrier, enables transient and reversible opening of the blood-brain barrier, thereby facilitating efficient and targeted drug delivery. Following intravenous administration in an AD mouse model, AFn-DPZ exhibited enhanced brain accumulation and sustained release of DPZ. This targeted delivery inhibited acetylcholinesterase activity, reduced amyloid plaque burden, alleviated neuroinflammation, attenuated oxidative damage, restored mitochondrial function, and upregulated the expression of brain-derived neurotrophic factor (BDNF).

Leukocyte immunoglobulin-like receptor B4 (LILRB4/ILT3) has recently emerged as an inhibitory microglial immune checkpoint implicated in ApoE-mediated suppression of amyloid-β (Aβ) clearance and inflammatory signaling, supporting its potential as a therapeutic target in AD. Here, we applied DNA-encoded library (DEL) screening of approximately 3.6 billion compounds to identify small molecule binders of LILRB4. Biophysical validation identified APX1 as a direct LILRB4 ligand with submicromolar affinity, which was further confirmed by cellular thermal shift assay (CETSA). Docking-guided mutagenesis studies defined a discrete ligand-binding interface involving key hotspot residues required for stable target engagement. Functionally, APX1 disrupted the LILRB4-ApoE interaction in orthogonal ELISA and biolayer interferometry assays. In human iPSC-derived microglia, APX1 suppressed SHP1/2 phosphorylation, attenuated NF-κB activation and IL-1β secretion, and restored Aβ42 uptake under ApoE-driven inflammatory conditions. APX1 further demonstrated favorable in vitro developability, metabolic stability, and CNS exposure properties. In the 5xFAD mouse model of AD, oral administration of APX1 improved cognitive performance, reduced cortical and hippocampal Aβ42 burden, suppressed neuroinflammatory cytokines, and decreased activated microglial populations.

The peptide's self-assembly and toxicity are highly dependent on its primary amino acid sequence and can be altered by modifying key residues. Specifically, the single amino acid substitutions A30W, K28A, and M35C can reduce the aggregation and toxicity of the Aβ42 peptide. In this study, we further evaluated the effects of these mutations in a C6 rat glioma cell line and in the Caenorhabditis elegans strains CL2006 and CL4176, which express muscular Aβ42 as an in vivo model. Our results showed that the A30W, K28A, and M35C substitutions reduce apoptosis induction in cell culture, in contrast to the WT Aβ42 peptide. In C. elegans, the three variants extended the lifespan of CL2006 worms by reducing fibrillar aggregates or altering aging, whereas the M35C peptide delayed the paralysis of CL4176 worms.

To address these limitations, this study proposes an interpretable multimodal framework, namely the Compact Biomarker Kolmogorov-Arnold Network (CBKAN).

In addition, a hybrid feature Transformer is used to fuse these imaging biomarkers with clinical and genetic data, explicitly capturing complementary relationships across modalities.

Although both agents have demonstrated therapeutic potential, their post-marketing adverse event reporting profiles remain insufficiently characterized and compared in spontaneous reporting systems. This study aimed to systematically compare adverse event signals associated with these two drugs using the FDA Adverse Event Reporting System database, with sex-stratified and sensitivity analyses performed to support the main findings. FAERS reports up to the fourth quarter of 2025 were retrospectively analyzed. Reports in which lecanemab or donanemab was recorded as the primary suspect drug were included. AEs were classified by system organ classes (SOCs) and preferred terms (PTs) according to the Medical Dictionary for Regulatory Activities (MedDRA). Signal detection was performed using four algorithms: reporting odds ratio (ROR), proportional reporting ratio (PRR), Bayesian confidence propagation neural network (BCPNN), and multi-item gamma Poisson shrinker (MGPS). Sex-stratified analysis, sensitivity analysis after excluding reports involving concomitant medications, and time-to-onset (TTO) analysis based on the Weibull shape parameter model were also conducted. False discovery rate (FDR) correction was applied to analyses involving multiple P values. A total of 3,640 AE reports were identified, including 2,602 for lecanemab and 1,038 for donanemab. Nervous system disorders was the most frequently reported SOC and the only SOC meeting the positivity criteria across all four algorithms for both drugs. At the PT level, the frequently reported events for both drugs were mainly concentrated in amyloid-related imaging abnormality (ARIA)-related events, including ARIA with oedema/effusion (ARIA-E) and ARIA with microhaemorrhages/haemosiderin deposition (ARIA-H), headache, and infusion-related reactions. The strongest disproportionality reporting signals were mainly observed for ARIA-related preferred terms and cerebral microhaemorrhage. In separate FAERS-based disproportionality analyses, lecanemab showed stronger disproportionality reporting signals for ARIA-H, whereas donanemab showed stronger disproportionality reporting signals for ARIA-E. In addition, drug-specific PT signal distributions differed between the two agents. Several potential novel PT signals were also identified. Sex-stratified analysis suggested differences in the distribution of certain PT signals between female and male reports. Sensitivity analysis supported the stability of most core signals. The median TTO was 46 days for lecanemab and 31 days for donanemab, and Weibull analysis suggested different temporal patterns of AE occurrence.

We review evidence showing that neuroinflammation in AD is stage-dependent, cell-state-specific, spatially organized, and functionally complex.

This pathogenesis is characterized by amyloid-β (Aβ) aggregation, tau hyperphosphorylation, persistent neuroinflammation, oxidative stress, and synaptic dysfunction. Conventional single-target interventions have consistently failed against this complex interplay of molecular events, thereby highlighting the need for multitarget, systems pharmacology approaches capable of simultaneously modulating convergent pathways. Apremilast (APR), an FDA-approved, orally bioavailable phosphodiesterase-4 (PDE4) inhibitor, has recently emerged as a favorable drug repurposing candidate capable of elevating intracellular cAMP and triggering a cascade of neuroprotective mechanisms. Preclinical investigations from Aβ-challenged neuronal cultures to high-fat diet/streptozotocin-induced rodent models of AD demonstrate that APR attenuates Aβ-induced cytotoxicity, improves cognitive performance, and preserves neuronal and synaptic integrity. Mechanistically, APR mitigates NF-κB-mediated neuroinflammation through IκBα stabilization, thereby reducing the release of proinflammatory cytokines such as TNF-α and IL-6; activates the Nrf2/HO-1 antioxidant defense pathway, and, via cAMP-dependent PI3K/Akt signaling, inhibits GSK-3β to prevent tau hyperphosphorylation, synaptic loss, and neuronal degeneration. This review synthesizes current mechanistic evidence supporting apremilast as a potential multitarget repurposing candidate in AD, thereby addressing key knowledge gaps in the current literature. All supporting evidence was compiled from peer-reviewed sources indexed in PubMed, Web of Science, and Scopus.

Repurposing drugs to target these mechanisms offers a promising approach to reduce the costs and duration of drug development. Genetic studies underscore the critical role of microglial clearance of amyloid-beta (Aβ) in AD pathogenesis. Specifically, soluble ST2 (sST2)-one of the two major isoforms of the ST2 protein encoded by the IL1RL1 (interleukin-1 receptor-like 1) gene-acts as a decoy receptor isoform that interferes with IL-33/ST2 signaling and has been identified as a disease-modifying factor that impairs microglial Aβ clearance functions. In this study, we investigated drug repurposing opportunities to modulate sST2 levels and alleviate AD pathologies. Unbiased screening of commonly used medications in AD patients, followed by validation in model systems, identified trazodone-an antidepressant used to treat major depressive disorder-as a leading negative regulator of sST2. Trazodone primarily suppresses sST2 expression through its antagonistic effects on adrenergic signaling. In the APP/PS1 transgenic mouse model of AD, trazodone treatment enhanced microglial interaction with Aβ and alleviated Aβ pathology. Furthermore, trazodone reduced neurodegeneration and rescued synaptic deficits in APP/PS1 mice. Comprehensive molecular profiling of APP/PS1 mouse brains showed that trazodone restored the expression of synaptic proteins critical for synaptic integrity and plasticity.

However, the timing of these alterations in vivo with respect to disease progression is unclear. Here, in longitudinal recordings from APP/PS1/PV-cre (AD mice) from 3-6 months, we found reduced sleep slow-wave power (0.5-4 Hz) in hippocampus and medial prefrontal cortex in AD mice as young as 3 months old, compared to non-AD (PV-cre) mice, well before overt pathology. This finding was primarily due to reductions in the NREM delta range (1.5-4 Hz), a hallmark of restorative functions of sleep. In contrast, beta (15-30 Hz) power linked to insomnia was significantly higher across all sleep-wake states. Loss of deep NREM sleep was not compensated by an increase in NREM sleep time, instead NREM sleep during the dark (active) phase was slightly but significantly lower in AD mice. 40-Hz auditory steady-state responses and associated evoked calcium responses of hippocampal PV neurons recorded using fiber photometry were also impaired by 3 months old.

There is mounting evidence suggesting that glymphatic dysfunction is an important cause of neurodegenerative diseases, characterized by failure of cerebrospinal fluid-interstitial fluid (CSF-ISF) exchange due to abnormal clearance. Mechanistically, this dysfunction is affected by aging, astroglial aquaporin-4 (AQP4) depolarization, vascular impairment, sleep abnormalities, oxidative damage, and neuroinflammation. Additionally, aberrant glymphatic flow acts as a crucial link between peripheral and central pathologies, amplifying neurodegeneration via altered solute transport and inflammation signaling.

However, whether Fc-mediated effector function is absolutely required for efficacy is not completely understood. This is important for optimizing therapeutic efficacy and mitigating side effects such as amyloid-related imaging abnormalities (ARIA). Antibodies lacking Fc effector function, like single-domain antibodies (nanobodies), offer a unique tool to dissect these mechanisms, as their small size facilitates blood-brain barrier (BBB) penetration and allows Fc-mediated functions to be studied independently. We immunized a llama with Aβ aggregates and constructed a phage display library to screen for aggregate-specific nanobodies. Lead candidates were characterized by epitope mapping and binding affinity to amyloid plaques in both murine and human AD brain tissues. We further assessed their BBB permeability and evaluated their efficacy in clearing pre-existing plaques in amyloid precursor protein (APP)/presenilin 1 (PS1) mice. We identified two lead nanobodies, 3A11 and 2D10, that bind distinct epitopes and specifically bind Aβ plaques in murine and human AD brain tissues. Following systemic administration, the monovalent, unmodified (Fc-less) 2D10 nanobody, but not 3A11, successfully crossed the BBB and engaged amyloid plaques in APP/PS1 mice. However, despite robust target engagement, the Fc-less 2D10 failed to recruit microglia or reduce plaque burden. In contrast, an engineered 2D10-Fc fusion antibody potently cleared amyloid plaques, achieving a reduction in pathology comparable to aducanumab treatment. This efficacy was directly correlated with Fc-mediated microglial recruitment and activation, demonstrating that the Fc domain is essential for phagocytic plaque removal. Our findings demonstrate that Fc effector function is indispensable for microglial-mediated amyloid clearance in vivo. By clarifying this fundamental mechanism, this study provides a framework for the rational design of next-generation immunotherapies.

Mirroring human disease, POWV strain LI9 directs age-dependent lethality in C57BL/6 (B6) mice, resulting in spongiform encephalitis, gliosis, and inflammatory cytokine/chemokine responses in the CNS. However, the mechanisms underlying age-dependent lethality and persistent neurodegenerative disease in POWV survivors remain to be resolved. Here, we analyzed cellular CNS responses to POWV LI9 infection in young (10-week-old) and aged (50-week-old) mice using single-cell RNA sequencing. Infection of young mice resulted in inflammatory CNS infiltrates (NK, CD4/CD8 T cells, and monocytes) and interferon responses that coincide with peak viral burden. In contrast, the CNS of aged infected mice instead featured upregulated astrocyte and neuronal genes associated with neurodegenerative and Alzheimer's disease pathways and the transition of homeostatic microglia to a Trem2-ApoE-linked disease-associated microglial transcriptional state. Histological analysis revealed that amyloid precursor protein (APP)/amyloid-β (Aβ) accumulated in the CNS following POWV infection and that POWV envelope protein and APP/Aβ were selectively localized within layers L5/L6 of the cerebral cortex. POWV kinetically increased perinuclear APP/Aβ accumulation during acute infection and was highly expressed in the CNS of POWV survivors. Our findings reveal that POWV triggers glial cell responses and a neurodegenerative disease-associated microglia program of Alzheimer's-like APP/Aβ accumulation in mice, which is consistent with long-term neurological sequelae in human POWV survivors.IMPORTANCEPowassan virus (POWV) causes lethal encephalitis and long-term cognitive deficits in survivors. Using an age-dependent murine model, we reveal that POWV-infected young mice direct robust CNS inflammatory infiltrates associated with viral clearance, whereas aged mice exhibit impaired immune responses and a shift from homeostatic to neurodegenerative glial cell states. POWV prompted the induction of disease-associated microglia (DAM) and Trem2-ApoE axis transcriptional responses that are hallmarks of APP/amyloid-β (Aβ) accumulation in Alzheimer's disease (AD). Remarkably, POWV induced progressive APP/Aβ accumulation in young and aged mice that persisted in survivors after viral clearance. This suggests that POWV induces an APP/Aβ neurodegenerative process and provides a potential cause of long-term neurological sequelae observed in human POWV survivors. Our data suggest that POWV initiates or exacerbates AD-like neuropathology and further rationalizes investigating the role of APP/Aβ responses in other encephalitic viruses."},{"quadrant":"Run1_Eval1_synthesis","attempt":4,"quote":"Lecanemab and donanemab are anti-amyloid-β (Aβ) monoclonal antibodies recently approved for the treatment of Alzheimer's disease (AD).","status":"PASS","error":"","abstract_text":"ID: 42440686\nTitle: Comparison of safety of lecanemab and donanemab: a real-world disproportionality analysis using the FDA adverse event reporting system.\nAbstract: Lecanemab and donanemab are anti-amyloid-β (Aβ) monoclonal antibodies recently approved for the treatment of Alzheimer's disease (AD).

We review evidence showing that neuroinflammation in AD is stage-dependent, cell-state-specific, spatially organized, and functionally complex. Microglia and astrocytes can aid in plaque containment, debris clearance, synaptic balance, metabolic adaptation, and tissue repair, but may also exacerbate injury through type-I interferon, inflammasome, complement, tumor necrosis factor, and lipid pathways.

This pathogenesis is characterized by amyloid-β (Aβ) aggregation, tau hyperphosphorylation, persistent neuroinflammation, oxidative stress, and synaptic dysfunction. Conventional single-target interventions have consistently failed against this complex interplay of molecular events, thereby highlighting the need for multitarget, systems pharmacology approaches capable of simultaneously modulating convergent pathways. Apremilast (APR), an FDA-approved, orally bioavailable phosphodiesterase-4 (PDE4) inhibitor, has recently emerged as a favorable drug repurposing candidate capable of elevating intracellular cAMP and triggering a cascade of neuroprotective mechanisms. Preclinical investigations from Aβ-challenged neuronal cultures to high-fat diet/streptozotocin-induced rodent models of AD demonstrate that APR attenuates Aβ-induced cytotoxicity, improves cognitive performance, and preserves neuronal and synaptic integrity. Mechanistically, APR mitigates NF-κB-mediated neuroinflammation through IκBα stabilization, thereby reducing the release of proinflammatory cytokines such as TNF-α and IL-6; activates the Nrf2/HO-1 antioxidant defense pathway, and, via cAMP-dependent PI3K/Akt signaling, inhibits GSK-3β to prevent tau hyperphosphorylation, synaptic loss, and neuronal degeneration. This review synthesizes current mechanistic evidence supporting apremilast as a potential multitarget repurposing candidate in AD, thereby addressing key knowledge gaps in the current literature. All supporting evidence was compiled from peer-reviewed sources indexed in PubMed, Web of Science, and Scopus.

Repurposing drugs to target these mechanisms offers a promising approach to reduce the costs and duration of drug development. Genetic studies underscore the critical role of microglial clearance of amyloid-beta (Aβ) in AD pathogenesis. Specifically, soluble ST2 (sST2)-one of the two major isoforms of the ST2 protein encoded by the IL1RL1 (interleukin-1 receptor-like 1) gene-acts as a decoy receptor isoform that interferes with IL-33/ST2 signaling and has been identified as a disease-modifying factor that impairs microglial Aβ clearance functions. In this study, we investigated drug repurposing opportunities to modulate sST2 levels and alleviate AD pathologies. Unbiased screening of commonly used medications in AD patients, followed by validation in model systems, identified trazodone-an antidepressant used to treat major depressive disorder-as a leading negative regulator of sST2. Trazodone primarily suppresses sST2 expression through its antagonistic effects on adrenergic signaling. In the APP/PS1 transgenic mouse model of AD, trazodone treatment enhanced microglial interaction with Aβ and alleviated Aβ pathology. Furthermore, trazodone reduced neurodegeneration and rescued synaptic deficits in APP/PS1 mice. Comprehensive molecular profiling of APP/PS1 mouse brains showed that trazodone restored the expression of synaptic proteins critical for synaptic integrity and plasticity.

However, the timing of these alterations in vivo with respect to disease progression is unclear. Here, in longitudinal recordings from APP/PS1/PV-cre (AD mice) from 3-6 months, we found reduced sleep slow-wave power (0.5-4 Hz) in hippocampus and medial prefrontal cortex in AD mice as young as 3 months old, compared to non-AD (PV-cre) mice, well before overt pathology. This finding was primarily due to reductions in the NREM delta range (1.5-4 Hz), a hallmark of restorative functions of sleep. In contrast, beta (15-30 Hz) power linked to insomnia was significantly higher across all sleep-wake states. Loss of deep NREM sleep was not compensated by an increase in NREM sleep time, instead NREM sleep during the dark (active) phase was slightly but significantly lower in AD mice. 40-Hz auditory steady-state responses and associated evoked calcium responses of hippocampal PV neurons recorded using fiber photometry were also impaired by 3 months old.

However, whether Fc-mediated effector function is absolutely required for efficacy is not completely understood. This is important for optimizing therapeutic efficacy and mitigating side effects such as amyloid-related imaging abnormalities (ARIA). Antibodies lacking Fc effector function, like single-domain antibodies (nanobodies), offer a unique tool to dissect these mechanisms, as their small size facilitates blood-brain barrier (BBB) penetration and allows Fc-mediated functions to be studied independently. We immunized a llama with Aβ aggregates and constructed a phage display library to screen for aggregate-specific nanobodies. Lead candidates were characterized by epitope mapping and binding affinity to amyloid plaques in both murine and human AD brain tissues. We further assessed their BBB permeability and evaluated their efficacy in clearing pre-existing plaques in amyloid precursor protein (APP)/presenilin 1 (PS1) mice. We identified two lead nanobodies, 3A11 and 2D10, that bind distinct epitopes and specifically bind Aβ plaques in murine and human AD brain tissues. Following systemic administration, the monovalent, unmodified (Fc-less) 2D10 nanobody, but not 3A11, successfully crossed the BBB and engaged amyloid plaques in APP/PS1 mice.

To overcome this, we developed a brain-targeted nanotherapeutic utilizing apoferritin (AFn) nanoparticles loaded with DPZ (AFn-DPZ). We demonstrate that this platform, by binding to the EphB1 receptor on the blood-brain barrier, enables transient and reversible opening of the blood-brain barrier, thereby facilitating efficient and targeted drug delivery. Following intravenous administration in an AD mouse model, AFn-DPZ exhibited enhanced brain accumulation and sustained release of DPZ. This targeted delivery inhibited acetylcholinesterase activity, reduced amyloid plaque burden, alleviated neuroinflammation, attenuated oxidative damage, restored mitochondrial function, and upregulated the expression of brain-derived neurotrophic factor (BDNF). Consequently, AFn-DPZ treatment significantly improved cognitive performance compared to free DPZ.

Especially, Alzheimer's Disease (AD) prediction is a very crucial process in AD metadata diagnosis.

The peptide's self-assembly and toxicity are highly dependent on its primary amino acid sequence and can be altered by modifying key residues. Specifically, the single amino acid substitutions A30W, K28A, and M35C can reduce the aggregation and toxicity of the Aβ42 peptide. In this study, we further evaluated the effects of these mutations in a C6 rat glioma cell line and in the Caenorhabditis elegans strains CL2006 and CL4176, which express muscular Aβ42 as an in vivo model. Our results showed that the A30W, K28A, and M35C substitutions reduce apoptosis induction in cell culture, in contrast to the WT Aβ42 peptide. In C. elegans, the three variants extended the lifespan of CL2006 worms by reducing fibrillar aggregates or altering aging, whereas the M35C peptide delayed the paralysis of CL4176 worms. Additionally, the substitutions altered oxidative stress and autophagy in control worms. Taken together, these results suggest that the A30W, K28A, and M35C substitutions reduce Aβ42 toxicity in cell culture and in C. elegans and could protect the nematode against Aβ42 toxicity."},{"quadrant":"Run1_Eval1_synthesis","attempt":4,"quote":"Intact mitophagy facilitates the timely clearance of damaged mitochondria, thereby limiting the release of mitochondrial DAMPs (e.g., mtDNA and mtROS) and helping restrain aberrant activation of the cGAS-STING pathway and the NLRP3 inflammasome.","status":"PASS","error":"","abstract_text":"ID: 42443967\nTitle: Microglial mitophagy as an immunometabolic checkpoint in alzheimer's disease: linking mitochondrial quality control to neuroinflammation.\nAbstract: AD is a complex neurodegenerative disorder characterized by chronic neuroinflammation. Microglia, the brain's resident immune cells, centrally regulate AD pathophysiology. Recent studies have highlighted microglial mitophagy as an important interface linking mitochondrial quality control to innate immune responses.Intact mitophagy facilitates the timely clearance of damaged mitochondria, thereby limiting the release of mitochondrial DAMPs (e.g., mtDNA and mtROS) and helping restrain aberrant activation of the cGAS-STING pathway and the NLRP3 inflammasome.In the AD pathological milieu, however, factors including Aβ deposition, tau pathology, and genetic risk variants such as TREM2 and APOE4 disrupt mitophagy at multiple levels-from initiation and recognition to lysosomal degradation. This review systematically summarizes the molecular regulatory network of microglial mitophagy, with a particular focus on the mechanisms by which AD-associated pathological factors impair this process. We further discuss potential mechanisms through which mitophagic dysfunction may contribute to the amplification of neuroinflammation, including the release of mitochondrial DAMPs, the reprogramming of TBK1 signaling, and intercellular interactions.

Although deep learning has achieved promising performance in AD diagnosis, existing multimodal models often operate as \"black boxes,\" lacking the transparency required for clinical practice and failing to explicitly model deep interactions between imaging and clinical features. To address these limitations, this study proposes an interpretable multimodal framework, namely the Compact Biomarker Kolmogorov-Arnold Network (CBKAN). Specifically, we introduce EHCTNet with disease-specific attention to extract features from 3D MRI data, and innovatively constrain the encoder to output a set of compact biomarkers instead of traditional high-dimensional abstract vectors, mimicking the diagnostic logic of clinicians (e.g., judging brain atrophy). In addition, a hybrid feature Transformer is used to fuse these imaging biomarkers with clinical and genetic data, explicitly capturing complementary relationships across modalities. Finally, the Kolmogorov-Arnold Network (KAN) is adopted as the classifier to effectively model the highly nonlinear characteristics of AD progression. Experiments on 800 subjects from the ADNI dataset show that CBKAN achieves 91.1% accuracy and an F1-score of 0.910 in the AD/MCI/CN classification task, significantly outperforming existing mainstream methods.

Mirroring human disease, POWV strain LI9 directs age-dependent lethality in C57BL/6 (B6) mice, resulting in spongiform encephalitis, gliosis, and inflammatory cytokine/chemokine responses in the CNS. However, the mechanisms underlying age-dependent lethality and persistent neurodegenerative disease in POWV survivors remain to be resolved. Here, we analyzed cellular CNS responses to POWV LI9 infection in young (10-week-old) and aged (50-week-old) mice using single-cell RNA sequencing. Infection of young mice resulted in inflammatory CNS infiltrates (NK, CD4/CD8 T cells, and monocytes) and interferon responses that coincide with peak viral burden. In contrast, the CNS of aged infected mice instead featured upregulated astrocyte and neuronal genes associated with neurodegenerative and Alzheimer's disease pathways and the transition of homeostatic microglia to a Trem2-ApoE-linked disease-associated microglial transcriptional state. Histological analysis revealed that amyloid precursor protein (APP)/amyloid-β (Aβ) accumulated in the CNS following POWV infection and that POWV envelope protein and APP/Aβ were selectively localized within layers L5/L6 of the cerebral cortex. POWV kinetically increased perinuclear APP/Aβ accumulation during acute infection and was highly expressed in the CNS of POWV survivors. Our findings reveal that POWV triggers glial cell responses and a neurodegenerative disease-associated microglia program of Alzheimer's-like APP/Aβ accumulation in mice, which is consistent with long-term neurological sequelae in human POWV survivors.IMPORTANCEPowassan virus (POWV) causes lethal encephalitis and long-term cognitive deficits in survivors. Using an age-dependent murine model, we reveal that POWV-infected young mice direct robust CNS inflammatory infiltrates associated with viral clearance, whereas aged mice exhibit impaired immune responses and a shift from homeostatic to neurodegenerative glial cell states. POWV prompted the induction of disease-associated microglia (DAM) and Trem2-ApoE axis transcriptional responses that are hallmarks of APP/amyloid-β (Aβ) accumulation in Alzheimer's disease (AD). Remarkably, POWV induced progressive APP/Aβ accumulation in young and aged mice that persisted in survivors after viral clearance. This suggests that POWV induces an APP/Aβ neurodegenerative process and provides a potential cause of long-term neurological sequelae observed in human POWV survivors. Our data suggest that POWV initiates or exacerbates AD-like neuropathology and further rationalizes investigating the role of APP/Aβ responses in other encephalitic viruses."}],"assistantLogs":[{"query":"Answer in English only.

This synthesis evaluates the emergence of next-generation therapeutic candidates, advanced machine-learning diagnostic pipelines, and systemic metabolic/immune mechanisms that modulate disease progression.\n\n### [INTRODUCTION & JUSTIFICATION]\nModern AD research has moved beyond the traditional amyloid-only hypothesis to address the multifactorial nature of the disease, including bioenergetic failure, neuroimmune dysfunction, and synaptic impairment. Immunotherapy, specifically via anti-amyloid monoclonal antibodies like lecanemab and donanemab, has shifted the clinical landscape, though safety profiles regarding amyloid-related imaging abnormalities remain critical areas of monitoring. Simultaneously, researchers are pioneering the \"Stage-State-Space Neuroimmune Reprogramming Model,\" which emphasizes the importance of aligning treatments with the specific inflammatory niche and glial state of the patient. Breakthroughs in drug delivery—such as nanocarriers that enable blood-brain barrier traversal—and artificial intelligence-driven diagnostic tools are bridging the gap between bench-side molecular discovery and clinical implementation.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Emerging \"Stage-State-Space\" models suggest neuroinflammation is spatially organized and cell-state-specific rather than a target for broad suppression.\n*   Artificial intelligence-driven frameworks, such as the Compact Biomarker Kolmogorov-Arnold Network (CBKAN), are providing transparent, non-black-box diagnostic pathways for AD classification.\n*   Peripheral-central immune axes, mediated by APOE4, reveal that systemic immune homeostasis directly impacts CNS neurodegeneration.\n*   Fc-mediated effector function of antibodies is now definitively recognized as essential for microglia-mediated plaque clearance, differentiating the efficacy of nanobodies from Fc-fused constructs.\n*   Single-cell sequencing of virus-infected murine models (Powassan virus) indicates that infectious agents may trigger progressive Alzheimer’s-like APP/Aβ accumulation that persists even after viral clearance.\n*   Glymphatic dysfunction is increasingly identified as an early driver of neurodegeneration, exacerbated by sleep abnormalities and astroglial AQP4 depolarization.\n*   Pharmacological agents like trazodone and apremilast are being successfully repurposed to address immune dysfunction, cAMP-PI3K signaling, and synaptic integrity.\n*   Novel liquid biopsy techniques, including those utilizing chimeric RNAs identified by the ChiTaRS 8.0/ChiTaH pipeline, are proving valuable for early detection.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

We review evidence showing that neuroinflammation in AD is stage-dependent, cell-state-specific, spatially organized, and functionally complex.

This pathogenesis is characterized by amyloid-β (Aβ) aggregation, tau hyperphosphorylation, persistent neuroinflammation, oxidative stress, and synaptic dysfunction. Conventional single-target interventions have consistently failed against this complex interplay of molecular events, thereby highlighting the need for multitarget, systems pharmacology approaches capable of simultaneously modulating convergent pathways. Apremilast (APR), an FDA-approved, orally bioavailable phosphodiesterase-4 (PDE4) inhibitor, has recently emerged as a favorable drug repurposing candidate capable of elevating intracellular cAMP and triggering a cascade of neuroprotective mechanisms. Preclinical investigations from Aβ-challenged neuronal cultures to high-fat diet/streptozotocin-induced rodent models of AD demonstrate that APR attenuates Aβ-induced cytotoxicity, improves cognitive performance, and preserves neuronal and synaptic integrity. Mechanistically, APR mitigates NF-κB-mediated neuroinflammation through IκBα stabilization, thereby reducing the release of proinflammatory cytokines such as TNF-α and IL-6; activates the Nrf2/HO-1 antioxidant defense pathway, and, via cAMP-dependent PI3K/Akt signaling, inhibits GSK-3β to prevent tau hyperphosphorylation, synaptic loss, and neuronal degeneration.

Repurposing drugs to target these mechanisms offers a promising approach to reduce the costs and duration of drug development. Genetic studies underscore the critical role of microglial clearance of amyloid-beta (Aβ) in AD pathogenesis. Specifically, soluble ST2 (sST2)-one of the two major isoforms of the ST2 protein encoded by the IL1RL1 (interleukin-1 receptor-like 1) gene-acts as a decoy receptor isoform that interferes with IL-33/ST2 signaling and has been identified as a disease-modifying factor that impairs microglial Aβ clearance functions. In this study, we investigated drug repurposing opportunities to modulate sST2 levels and alleviate AD pathologies. Unbiased screening of commonly used medications in AD patients, followed by validation in model systems, identified trazodone-an antidepressant used to treat major depressive disorder-as a leading negative regulator of sST2. Trazodone primarily suppresses sST2 expression through its antagonistic effects on adrenergic signaling. In the APP/PS1 transgenic mouse model of AD, trazodone treatment enhanced microglial interaction with Aβ and alleviated Aβ pathology. Furthermore, trazodone reduced neurodegeneration and rescued synaptic deficits in APP/PS1 mice. Comprehensive molecular profiling of APP/PS1 mouse brains showed that trazodone restored the expression of synaptic proteins critical for synaptic integrity and plasticity.

However, the timing of these alterations in vivo with respect to disease progression is unclear. Here, in longitudinal recordings from APP/PS1/PV-cre (AD mice) from 3-6 months, we found reduced sleep slow-wave power (0.5-4 Hz) in hippocampus and medial prefrontal cortex in AD mice as young as 3 months old, compared to non-AD (PV-cre) mice, well before overt pathology. This finding was primarily due to reductions in the NREM delta range (1.5-4 Hz), a hallmark of restorative functions of sleep. In contrast, beta (15-30 Hz) power linked to insomnia was significantly higher across all sleep-wake states. Loss of deep NREM sleep was not compensated by an increase in NREM sleep time, instead NREM sleep during the dark (active) phase was slightly but significantly lower in AD mice. 40-Hz auditory steady-state responses and associated evoked calcium responses of hippocampal PV neurons recorded using fiber photometry were also impaired by 3 months old.

However, whether Fc-mediated effector function is absolutely required for efficacy is not completely understood. This is important for optimizing therapeutic efficacy and mitigating side effects such as amyloid-related imaging abnormalities (ARIA). Antibodies lacking Fc effector function, like single-domain antibodies (nanobodies), offer a unique tool to dissect these mechanisms, as their small size facilitates blood-brain barrier (BBB) penetration and allows Fc-mediated functions to be studied independently. We immunized a llama with Aβ aggregates and constructed a phage display library to screen for aggregate-specific nanobodies. Lead candidates were characterized by epitope mapping and binding affinity to amyloid plaques in both murine and human AD brain tissues. We further assessed their BBB permeability and evaluated their efficacy in clearing pre-existing plaques in amyloid precursor protein (APP)/presenilin 1 (PS1) mice. We identified two lead nanobodies, 3A11 and 2D10, that bind distinct epitopes and specifically bind Aβ plaques in murine and human AD brain tissues. Following systemic administration, the monovalent, unmodified (Fc-less) 2D10 nanobody, but not 3A11, successfully crossed the BBB and engaged amyloid plaques in APP/PS1 mice. However, despite robust target engagement, the Fc-less 2D10 failed to recruit microglia or reduce plaque burden. In contrast, an engineered 2D10-Fc fusion antibody potently cleared amyloid plaques, achieving a reduction in pathology comparable to aducanumab treatment. This efficacy was directly correlated with Fc-mediated microglial recruitment and activation, demonstrating that the Fc domain is essential for phagocytic plaque removal. Our findings demonstrate that Fc effector function is indispensable for microglial-mediated amyloid clearance in vivo. By clarifying this fundamental mechanism, this study provides a framework for the rational design of next-generation immunotherapies.

While DPZ has multi-faceted benefits, its clinical efficacy is constrained by poor BBB penetration, requiring high doses that lead to significant side effects. To overcome this, we developed a brain-targeted nanotherapeutic utilizing apoferritin (AFn) nanoparticles loaded with DPZ (AFn-DPZ). We demonstrate that this platform, by binding to the EphB1 receptor on the blood-brain barrier, enables transient and reversible opening of the blood-brain barrier, thereby facilitating efficient and targeted drug delivery. Following intravenous administration in an AD mouse model, AFn-DPZ exhibited enhanced brain accumulation and sustained release of DPZ. This targeted delivery inhibited acetylcholinesterase activity, reduced amyloid plaque burden, alleviated neuroinflammation, attenuated oxidative damage, restored mitochondrial function, and upregulated the expression of brain-derived neurotrophic factor (BDNF).

However, the mechanisms underlying age-dependent lethality and persistent neurodegenerative disease in POWV survivors remain to be resolved. Here, we analyzed cellular CNS responses to POWV LI9 infection in young (10-week-old) and aged (50-week-old) mice using single-cell RNA sequencing. Infection of young mice resulted in inflammatory CNS infiltrates (NK, CD4/CD8 T cells, and monocytes) and interferon responses that coincide with peak viral burden. In contrast, the CNS of aged infected mice instead featured upregulated astrocyte and neuronal genes associated with neurodegenerative and Alzheimer's disease pathways and the transition of homeostatic microglia to a Trem2-ApoE-linked disease-associated microglial transcriptional state.

This synthesis evaluates the emergence of next-generation therapeutic candidates, advanced machine-learning diagnostic pipelines, and systemic metabolic/immune mechanisms that modulate disease progression.\n\n### [INTRODUCTION & JUSTIFICATION]\nModern AD research has moved beyond the traditional amyloid-only hypothesis to address the multifactorial nature of the disease, including bioenergetic failure, neuroimmune dysfunction, and synaptic impairment. Immunotherapy, specifically via anti-amyloid monoclonal antibodies like lecanemab and donanemab, has shifted the clinical landscape, though safety profiles regarding amyloid-related imaging abnormalities remain critical areas of monitoring. Simultaneously, researchers are pioneering the \"Stage-State-Space Neuroimmune Reprogramming Model,\" which emphasizes the importance of aligning treatments with the specific inflammatory niche and glial state of the patient. Breakthroughs in drug delivery—such as nanocarriers that enable blood-brain barrier traversal—and artificial intelligence-driven diagnostic tools are bridging the gap between bench-side molecular discovery and clinical implementation.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Emerging \"Stage-State-Space\" models suggest neuroinflammation is spatially organized and cell-state-specific rather than a target for broad suppression.\n*   Artificial intelligence-driven frameworks, such as the Compact Biomarker Kolmogorov-Arnold Network (CBKAN), are providing transparent, non-black-box diagnostic pathways for AD classification.\n*   Peripheral-central immune axes, mediated by APOE4, reveal that systemic immune homeostasis directly impacts CNS neurodegeneration.\n*   Fc-mediated effector function of antibodies is now definitively recognized as essential for microglia-mediated plaque clearance, differentiating the efficacy of nanobodies from Fc-fused constructs.\n*   Single-cell sequencing of virus-infected murine models (Powassan virus) indicates that infectious agents may trigger progressive Alzheimer’s-like APP/Aβ accumulation that persists even after viral clearance.\n*   Glymphatic dysfunction is increasingly identified as an early driver of neurodegeneration, exacerbated by sleep abnormalities and astroglial AQP4 depolarization.\n*   Pharmacological agents like trazodone and apremilast are being successfully repurposed to address immune dysfunction, cAMP-PI3K signaling, and synaptic integrity.\n*   Novel liquid biopsy techniques, including those utilizing chimeric RNAs identified by the ChiTaRS 8.0/ChiTaH pipeline, are proving valuable for early detection.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

In this work, we developed a highly sensitive electrochemiluminescence (ECL) aptasensor for detecting a key AD biomarker, Tau protein. An all-inorganic perovskite CsPbBr3 nanocrystals (NCs) were used as ECL emitters and were encapsulated with polyvinylpyrrolidone (PVP) to improve the stability of CsPbBr3 NCs in aqueous solution. Moreover, -PVP encapsulation significantly enhanced the ECL response via coordination between the lone-pair electrons of oxygen atoms and Pb2+. The obtained CsPbBr3@PVP composite was further functionalized with gold nanoparticles, which served as anchoring sites for the immobilization of a Tau-specific aptamer. The sensing mechanism relies on the specific recognition between the surface-bound aptamer and the Tau protein. The formation of the aptamer-target complex impeded the ECL reaction efficiency of the system, resulting in an \"off\" ECL sensing response. This strategy enables ultrasensitive detection of Tau protein with a wide linear range from 10 fg/mL to 108 fg/mL and a detection limit as low as 0.80 fg/mL. The aptasensor also demonstrated satisfactory recoveries of 97.2% to 108.6% in mouse cerebrospinal fluid with relative standard deviations below 6.5%, indicating its promising potential for early diagnosis of AD.\n\nID: 42447420\nTitle: Orexin, Sleep, and Cognition in Alzheimer Disease: Non-REM Oscillatory Activity and Neural Resilience.\nAbstract: Sleep-wake dysregulation and elevated CSF orexin have been implicated in Alzheimer disease (AD). Sleep spindles (SPs) and slow oscillations (SOs) are linked to cognition and neurodegeneration; however, their relationship with CSF orexin concentrations in symptomatic AD has not been characterized. We investigated whether nonrapid eye movement (NREM) SP-SO activity is associated with CSF orexin and whether these oscillatory features moderate associations between orexin, cognition, neuropsychiatric symptom severity, and AD biomarkers. This prospective observational cohort study was conducted at a tertiary memory clinic in Lleida, Spain. Individuals aged ≥60 years with biomarker-confirmed mild-to-moderate AD (National Institute on Aging-Alzheimer's Association criteria) underwent overnight polysomnography and morning CSF sampling. SP and SO were detected using validated automated algorithms with independent verification and visual quality control. CSF was assayed for orexin-A, amyloid-β42 (Aβ42), phosphorylated tau181 (pTau181), total tau, and YKL-40. Cognitive performance Alzheimer's Disease Assessment Scale-Cognitive Subscale ([ADAS-Cog], Mini-Mental State Examination (MMSE), California verbal learning test, ROCF) and neuropsychiatric symptoms (NPI) were assessed longitudinally over 36 months. Associations were examined using generalized linear models with robust estimators adjusted for age, sex, Aβ42, and apnea-hypopnea index. Multiple comparisons were controlled using false discovery rate correction. Interaction terms assessed moderation effects. Sixty participants (30 women; mean age 74.7 years) were included. Longer SO duration and higher SP density and power were associated with lower CSF orexin concentrations (SP density: β = -187.37 pg/mL, 95% CI -344.93 to -29.80). Orexin was not associated with global sleep continuity metrics. Higher CSF orexin concentrations were associated with worse global cognition (ADAS-Cog: β = 0.014, 95% CI 0.003-0.024; MMSE: β = -0.01, 95% CI -0.011 to -0.004) and greater neuropsychiatric symptom severity (NPI at: β = 0.03, 95% CI 0.011-0.041). Higher orexin was also associated with higher pTau181 (β = 0.11, 95% CI 0.04-0.19), total tau, and YKL-40 (β = 0.37, 95% CI 0.17-0.57). Significant orexin × SP-SO interactions were observed, such that greater oscillatory activity attenuated the adverse associations between orexin and cognitive outcomes, independent of Aβ42 and tau. In biomarker-confirmed AD, NREM SP and SO activity are associated with CSF orexin concentrations and moderate associations between orexin and longitudinal cognitive and neuropsychiatric outcomes. Limitations include the observational design and absence of a comparator group, precluding causal inference and limiting contextualization relative to normal aging. NREM oscillatory metrics and orexin concentrations may represent complementary physiologic markers for disease monitoring and therapeutic targeting.

A Reliable Tool for Detecting Subtle Cognitive Decline in Mild Cognitive Impairment and Mild Alzheimer's Disease.\nAbstract: Neurodegenerative diseases, notably Alzheimer's disease (AD), present a significant public health challenge. This study aims to evaluate the effectiveness of the Ecological Assessment Battery for Numbers (EABN) in detecting subtle cognitive decline in mild cognitive impairment (MCI) and mild AD, focusing on everyday life mathematical situations. This cross-sectional study involved 66 participants (21 mild AD, 23 MCI, and 22 controls). Clinical assessments included the Mini-Mental State Examination (MMSE), the EABN, and the Numerical Activities of Daily Living questionnaire. Statistical analyses utilized nonparametric tests, Spearman rank correlation, and receiver operating characteristic curve analyses. The EABN demonstrated an area under the curve (AUC) of 0.83 (95% confidence interval [0.73, 0.92]) in distinguishing patients and controls. Patients with pathologically high EABN scores were significantly older, and a positive correlation was observed between EABN and MMSE scores (r = .30; p = .04). The Appointment subtest within EABN emerged as the most discriminative (AUC = 0.86). Among MCI patients with pathological EABN scores, 70% progressed to AD or amyloid angiopathy. This study reveals early manifestation of mathematical cognition impairments in cognitive decline, even before patient-reported complaints. The EABN, a practical tool for ecological assessment, could aid in early diagnosis and guide interventions. Integrating mathematical cognition assessment into routine care aligns with recommendations for cognitive rehabilitation in MCI patients, potentially preventing autonomy loss. These findings underscore the significance of a comprehensive approach to patient management, incorporating ecological assessments for nuanced diagnostics and early intervention in neurodegenerative diseases.\n\nID: 42446992\nTitle: Repurposing trazodone for Alzheimer's disease to modulate soluble ST2 levels and alleviate Alzheimer's pathology.\nAbstract: Alzheimer's disease (AD) is a multifactorial disorder involving various pathological mechanisms, such as amyloidosis, immune dysfunctions, and synaptic impairments, which are important therapeutic targets. Repurposing drugs to target these mechanisms offers a promising approach to reduce the costs and duration of drug development. Genetic studies underscore the critical role of microglial clearance of amyloid-beta (Aβ) in AD pathogenesis. Specifically, soluble ST2 (sST2)-one of the two major isoforms of the ST2 protein encoded by the IL1RL1 (interleukin-1 receptor-like 1) gene-acts as a decoy receptor isoform that interferes with IL-33/ST2 signaling and has been identified as a disease-modifying factor that impairs microglial Aβ clearance functions. In this study, we investigated drug repurposing opportunities to modulate sST2 levels and alleviate AD pathologies. Unbiased screening of commonly used medications in AD patients, followed by validation in model systems, identified trazodone-an antidepressant used to treat major depressive disorder-as a leading negative regulator of sST2. Trazodone primarily suppresses sST2 expression through its antagonistic effects on adrenergic signaling. In the APP/PS1 transgenic mouse model of AD, trazodone treatment enhanced microglial interaction with Aβ and alleviated Aβ pathology. Furthermore, trazodone reduced neurodegeneration and rescued synaptic deficits in APP/PS1 mice. Comprehensive molecular profiling of APP/PS1 mouse brains showed that trazodone restored the expression of synaptic proteins critical for synaptic integrity and plasticity. Overall, these findings demonstrate that trazodone is a promising repurposing candidate for AD that targets underlying immune dysfunctions and synaptic impairment.\n\nID: 42446988\nTitle: 3D nanoscale imaging of amyloid-β oligomer interactions with extracellular vesicles by cryo-ET.\nAbstract: Central to Alzheimer's disease pathology are prefibrillar oligomer assemblies of amyloid-β (Aβ) peptide. A widely discussed hypothesis proposes that amyloid-β oligomers insert into neuronal lipid membranes, disrupting their integrity and causing a loss of cellular homeostasis in Alzheimer's disease. This membrane disruption is believed to be a major source of Aβ-induced neurotoxicity. Cryo electron tomography (cryo-ET) has facilitated 3D nanoscale imaging of Aβ-membrane interactions under near-native conditions. Analyses of small extracellular vesicles (sEVs) reveals that Aβ oligomers including annular and curvilinear extended oligomers (CLEOs) exhibit extensive binding to cell-derived lipid membranes, including insertion into and carpeting of the lipid bilayer. Notably, these oligomeric assemblies were also internalized and concentrated within the cell-derived exosomes and other small sEVs. Enrichment of Aβ oligomers within the vesicles typically ranged between 5 to 20 times the external Aβ levels depending on the vesicle size and curvature. In contrast, monomeric and fibrillar forms of Aβ displayed minimal membrane interaction. Once internalized CLEOs appear to be trapped in an oligomeric form and do not readily go on to form fibrils. Studies with vesicles of brain lipid extract indicate the Aβ internalization does not require the presence of a membrane protein. Our in vitro studies underscore the membrane-disruptive capacity of oligomeric Aβ species and suggest a role of sEVs in concentrating toxic Aβ oligomers and transporting oligomers across the brain interstitium.\n\nID: 42446869\nTitle: Single-cell analysis of Powassan virus-infected brains reveals age-dependent neuroinflammatory crosstalk and progressive Alzheimer's-like APP/Aβ accumulation.\nAbstract: Powassan virus (POWV) causes lethal encephalitis in the elderly and long-term neurological sequelae in survivors. Mirroring human disease, POWV strain LI9 directs age-dependent lethality in C57BL/6 (B6) mice, resulting in spongiform encephalitis, gliosis, and inflammatory cytokine/chemokine responses in the CNS. However, the mechanisms underlying age-dependent lethality and persistent neurodegenerative disease in POWV survivors remain to be resolved. Here, we analyzed cellular CNS responses to POWV LI9 infection in young (10-week-old) and aged (50-week-old) mice using single-cell RNA sequencing. Infection of young mice resulted in inflammatory CNS infiltrates (NK, CD4/CD8 T cells, and monocytes) and interferon responses that coincide with peak viral burden. In contrast, the CNS of aged infected mice instead featured upregulated astrocyte and neuronal genes associated with neurodegenerative and Alzheimer's disease pathways and the transition of homeostatic microglia to a Trem2-ApoE-linked disease-associated microglial transcriptional state. Histological analysis revealed that amyloid precursor protein (APP)/amyloid-β (Aβ) accumulated in the CNS following POWV infection and that POWV envelope protein and APP/Aβ were selectively localized within layers L5/L6 of the cerebral cortex. POWV kinetically increased perinuclear APP/Aβ accumulation during acute infection and was highly expressed in the CNS of POWV survivors. Our findings reveal that POWV triggers glial cell responses and a neurodegenerative disease-associated microglia program of Alzheimer's-like APP/Aβ accumulation in mice, which is consistent with long-term neurological sequelae in human POWV survivors.IMPORTANCEPowassan virus (POWV) causes lethal encephalitis and long-term cognitive deficits in survivors. Using an age-dependent murine model, we reveal that POWV-infected young mice direct robust CNS inflammatory infiltrates associated with viral clearance, whereas aged mice exhibit impaired immune responses and a shift from homeostatic to neurodegenerative glial cell states. POWV prompted the induction of disease-associated microglia (DAM) and Trem2-ApoE axis transcriptional responses that are hallmarks of APP/amyloid-β (Aβ) accumulation in Alzheimer's disease (AD). Remarkably, POWV induced progressive APP/Aβ accumulation in young and aged mice that persisted in survivors after viral clearance. This suggests that POWV induces an APP/Aβ neurodegenerative process and provides a potential cause of long-term neurological sequelae observed in human POWV survivors. Our data suggest that POWV initiates or exacerbates AD-like neuropathology and further rationalizes investigating the role of APP/Aβ responses in other encephalitic viruses.\n\nID: 42446837\nTitle: Molecular Regulation of Pyroptosis in Alzheimer's Disease: Linking Neuroinflammation, Cell Death, and Therapeutic Targeting.\nAbstract: Alzheimer's disease (AD) is a progressive neurodegenerative disorder characterized by profound cognitive decline, wherein chronic neuroinflammation plays a pivotal pathogenic role. Central to this inflammatory milieu is pyroptosis, a highly inflammatory form of programmed lytic cell death mediated by gasdermin proteins. This comprehensive review provides an in-depth synthesis of the cellular and molecular mechanisms underlying pyroptosis in AD. We detail the distinct roles of microglia as primary initiators responding to amyloid-beta (Aβ) and tau aggregates, alongside the specific vulnerabilities of neurons facing oxidative stress, astrocytes impacting metabolic support, and endothelial cells whose pyroptotic death contributes directly to blood-brain barrier disruption. At the molecular level, the priming and activation of the NLRP3 and NLRP1 inflammasomes by diverse triggers, including classical markers like Aβ, environmental neurotoxicants and metabolic stressors, converge on caspase-1 and caspase-8 activation. This cascade culminates in gasdermin D (GSDMD) and gasdermin E (GSDME) pore formation, leading to cellular lysis and the massive release of pro-inflammatory cytokines such as IL-1β and IL-18. Furthermore, this paper explores the emerging and critical concept of PANoptosis, highlighting the intricate crosstalk between pyroptosis, apoptosis, and necroptosis within PANoptosome complexes triggered by mitochondrial dysfunction. We evaluate current and prospective therapeutic strategies, ranging from multi-target natural and traditional herbal remedies to advanced nanomedicine, synthetic small molecules, and epigenetic gene therapies. By integrating insights from blood-based pyroptosis-associated molecular signatures and advanced targeted drug delivery systems, we emphasize the critical need for personalized, multi-targeted approaches to successfully harness pyroptosis modulation in the clinical management and treatment of AD.\n\nID: 42446728\nTitle: Protein kinases as therapeutic targets in Alzheimer's disease: challenges, insights, and new frontiers.\nAbstract: Alzheimer's disease (AD) remains the leading cause of dementia worldwide, imposing an enormous and growing societal burden with more than 55 million people affected globally. Despite decades of intensive investigation, existing therapeutic options provide only modest symptomatic relief and fail to prevent or slow disease progression, emphasizing the critical need for interventions that target the fundamental molecular mechanisms of neurodegeneration. Pathologically, Alzheimer's disease is characterized by extracellular accumulation of amyloid-β plaques, intracellular neurofibrillary tangles formed by hyperphosphorylated tau, profound synaptic loss, chronic neuroinflammation, and extensive neuronal degeneration. Although amyloid-focused strategies have long dominated drug development, their limited clinical benefit and safety liabilities highlight the multifactorial nature of AD and the need to move beyond amyloid-centric paradigms. Protein kinases have emerged as key integrators of multiple pathogenic processes in AD, governing tau phosphorylation, amyloid precursor protein processing, synaptic signaling, and neuroimmune responses. Aberrant kinase signaling drives tau pathology and propagation, promotes amyloidogenic pathways, disrupts synaptic function, and perpetuates inflammatory cascades. While extensive work on kinases such as GSK-3β, CDK5, JNKs, and CSF1R has firmly established the relevance of kinase dysregulation in AD, no kinase-directed therapy has yet translated into clinical success. This review highlights emerging kinase targets beyond these classical pathways, including Fyn, Casein Kinase 1 Delta (CK1δ), Tau-Tubulin Kinase 1 (TTBK1), and Dual Leucine Zipper Kinase (DLK), which are supported by mechanistic insights and compelling preclinical evidence. Continued advances in brain-penetrant, isoform-selective, and mechanism-driven kinase inhibitor design may enable the development of next-generation disease-modifying therapies for Alzheimer's disease.\n\nID: 42446696\nTitle: 4-methylbenzyl 5-arylthiophene-2-carboxylates as Multitarget Directed Ligands Scaffolds (MTDLs): Synthesis, in-silico docking studies, and evaluation of dual selective enzymatic inhibition (AChE & MAO-B).\nAbstract: Single-target ligands have insufficient effectiveness in treating Alzheimer's disease (AD), leading to the development of new pharmacological strategies, particularly multi-target-directed ligands (MTDLs) that tackle the multifactorial nature of the impairment. Among these, dual inhibition of acetylcholinesterase (AChE) and monoamine oxidase B (MAO-B) represents a promising approach for enhancing therapeutic outcomes. Here, analogs of 4-methylbenzyl 5-arylthiophene-2-carboxylates (5a-5h) were identified as dual inhibitors of AChE and MAO-B. In vitro evaluations demonstrated that 5a-5d exhibited the most promising inhibition potential towards targeted enzymes (AChE and MAO-B), having IC50 values 0.72 ± 0.01 µM to 1.69 ± 0.04 µM for AChE and 0.19 ± 0.03 µM to 2.69 ± 0.10 µM for MAO-B. Docking analysis is consistent with the in vitro studies, critically unveiling bindings, commonly hydrogen interactions, π-Sulphur, π-π interaction, π-alkyl, and alkyl-alkyl ligand and enzyme binding interactions.

Based on brain tissue proteomics of patients with AD, we screened out the subtypes of patients that are coordinately regulated by cellular senescence-related proteins and RNA modification regulators. Transcriptome datasets were used to validate and evaluate 20 hub proteins identified using 100 integrated machine learning algorithms. Finally, protein and metabolic data were employed to explore the characteristics of metabolic subtypes and pathways in AD progression. The diagnostic model had good diagnostic performance, as revealed by the average area under the receiver operating characteristic curve (AUC) = 0.885 of the internal datasets and the average AUC = 0.89 of transcriptome datasets. Risk score can be used to assess disease progression and the corresponding changes in metabolic characteristics. Finally, metabolic analysis indicates significant abnormalities in amino acid and lipid metabolism during the progression of AD. We revealed the potential role of RNA modification regulators and cellular senescence-related proteins in AD pathogenesis and related diagnostic markers through proteomic analysis and machine learning-based methods.\n\nID: 42446245\nTitle: Speech-In-Noise Perception in Alzheimer's Disease and Primary Progressive Aphasia.\nAbstract: Understanding speech despite background noise is essential for everyday communication, but makes heavy neural processing demands. It is therefore potentially vulnerable to neurodegenerative diseases, particularly those led by communication deficits (primary progressive aphasia). However, how speech-in-noise perception is affected in these diseases is poorly understood. Here we addressed this in 59 patients representing typical Alzheimer's disease and canonical logopenic, nonfluent/agrammatic and semantic variant syndromes of primary progressive aphasia, compared with 24 cognitively-well, older controls. We administered a digit triplet test of speech-in-noise perception based on the task used in the UK Biobank study, alongside pure tone audiometry and a general neuropsychological assessment. Voxel-based morphometry of patients' brain MRI scans was used to identify structural neuroanatomical associations of speech-in-noise perception. After adjusting for age, peripheral hearing and general cognitive function, the Alzheimer's, logopenic and nonfluent primary progressive aphasia groups performed significantly worse on speech-in-noise perception than controls. The nonfluent primary progressive aphasia and Alzheimer groups additionally had significantly worse peripheral hearing function than controls. Speech-in-noise perceptual performance correlated with grey matter atrophy in the right supramarginal gyrus. Profiles of central (brain) and peripheral hearing impairment stratify major dementias, with implications for diagnosis and development of interventions to improve real-world communication in people living with dementia.\n\nID: 42446082\nTitle: The economic burden of dementia in Europe: COIN-Eu dementia.\nAbstract: BackgroundDementia, with Alzheimer's disease as its most common underlying cause, is a major contributor to disability, dependency, and death, imposing significant societal and economic burdens across Europe. Despite its growing prevalence, cross-country cost estimates remain scarce and highly heterogeneous, limiting comparability.ObjectiveTo estimate country-level societal costs of dementia in Europe and to derive aggregate European cost estimates, including direct costs, indirect costs (productivity losses), and informal care costs.MethodsA standardized review of dementia cost assessments conducted in Europe was performed. Heterogeneous cost-estimation approaches were harmonized using pooling and health-economic imputation techniques to address data gaps and generate country-level estimates. All cost estimates were converted to 2019 euros using Consumer Price Indices and Purchasing Power Parities (PPP). Informal care costs were analyzed separately to reflect their complexity and substantial contribution to total costs.ResultsForty-five studies were identified. Annual societal costs of dementia in high-income European countries totaled €221.4 billion (€PPP, 2019; €25,218 per patient) for 8.8 million people with dementia. Informal care and direct costs accounted for 58% and 42% of total costs, respectively. Indirect costs contributed minimally to total costs. Substantial variation in per patient costs across countries was observed.ConclusionsDementia care imposes substantial societal burdens, largely driven by informal care. Owing to data availability, estimates were limited to high-income European countries. Future research should focus on standardizing cost assessment methods, improving informal care valuation, expanding evidence from low- and middle-income countries, and evaluating the financial impact of emerging treatments and prevention strategies.\n\nID: 42446006\nTitle: Algorithmic Choreography: Redefining Human and Non-Human Relations in Digital Health.\nAbstract: This article contributes to the growing debate on algorithms in digital health, which has expanded alongside the integration of algorithmic technologies into diverse healthcare practices and contexts. Although much of the existing literature adopts a deterministic perspective, focusing on the impact of algorithms on society, we propose a different approach. Drawing on the concept of algorithmic choreography, we show how humans and algorithmic technologies \"gear together\" in shared performances. Based on an ethnographic study in a nursing home for people with dementia, we examine a telemonitoring algorithmic system designed to prevent adverse events and how it enters into relations with the humans inhabiting this healthcare organization. The system gives rise to two distinct choreographies: night monitoring, in which staff use it for real-time observation of residents' movements and quantified decision-making, where algorithmically generated indexes support longitudinal assessments of residents' health status. We argue that in both choreographies, humans remain central rather than passive recipients of innovation. Care professionals give or withhold agency from algorithms, sustain their functioning and engage in collective improvisations through which human-nonhuman interactions are continually reshaped.\n\nID: 42445988\nTitle: CSF1R inhibition exacerbates gamma oscillation disruption and induces network hyperexcitability in APP/PS1 mice.\nAbstract: Alzheimer's Disease is the most common neurodegenerative disease worldwide, but significant gaps in pathophysiological understanding have hampered development of disease-modifying therapies. In Alzheimer's disease, neurophysiological function is impaired, with gamma frequency oscillations - thought to be essential for higher-order cognitive processes - disrupted in both patients and animal models. However, the mechanisms driving these disruptions are unclear and, in particular, the role of neuroinflammation in these changes is poorly understood. In this study, we investigated neuronal network dynamics in acute brain slices from APP/PS1 transgenic mice. Gamma frequency oscillations had significantly reduced amplitude in APP/PS1 brain slices at 9-11 months, accompanied by an increase in beta frequency power and heightened epileptiform activity. This is suggestive of a slowing in neuronal oscillations, considered a neurophysiological hallmark of Alzheimer's disease. Immunohistochemical analysis revealed a reduction in parvalbumin- and somatostatin-positive inhibitory interneuron populations. Treatment with gabazine demonstrated increased network sensitivity to GABAA receptor antagonism, further indicating compromised inhibitory control in APP/PS1. As these altered oscillatory dynamics correlated with microglial reactivity, we hypothesised a causal role for microglia. Administration of the CSF1R inhibitor GW2580 reduced microglial proliferation, attenuated development of the disease-associated microglial phenotype and partially rescued synaptic loss; but, had no significant impact on amyloid plaque burden or cognitive deficits. Unexpectedly, GW2580 treatment exacerbated neuronal network hyperactivity and the incidence and complexity of epileptiform activity. Microglia in GW2580-treated mice showed reduced CD68 expression and decreased engulfment of synaptic elements, potentially facilitating the persistence of hyperexcitable synapses. These findings support a role of microglia in regulating neuronal network homeostasis and caution against indiscriminate suppression of microglial activity in Alzheimer's disease. Therapeutic strategies targeting microglia must account for their homeostatic functions to avoid adverse effects on neuronal network stability.\n\nID: 42445718\nTitle: Central neural circuits and their associated mechanisms of inter-organ crosstalk.\nAbstract: The central nervous system (CNS), which comprises the brain and spinal cord, serves as the core regulatory hub for maintaining homeostasis and coordinating diverse physiological functions. These functions include interoception, cognition, and social behavior. The intricate architecture and extensive connectivity of the CNS enable integration of multi-system responses, thereby ensuring bodily stability and adaptability. The CNS exerts profound regulatory influences on fundamental life-sustaining processes and higher-order cognitive and social functions. This is mediated by distinct neural circuits and molecular mechanisms. CNS dysfunction is strongly associated with the pathogenesis of neurological disorders (Alzheimer's disease, Parkinson's disease, stroke and epilepsy), metabolic diseases (obesity and diabetes), and cardiovascular conditions (hypertension and atherosclerosis). Given the pivotal role of the CNS in both physiological regulation and disease progression, a comprehensive understanding of CNS mechanisms is critical for identifying therapeutic targets. This review systematically examines the regulatory functions of the CNS in physiology and disease. Moreover, this review analyzes the underlying molecular and circuit-level mechanisms, and discusses potential therapeutic strategies. By elucidating the systemic interactions of the CNS, this study aims to highlight its potential as a target for innovative interventions in disease prevention, diagnosis, and treatment.\n\nID: 42445345\nTitle: Changes in cortical plasticity induced by paired associative stimulation in people with mild cognitive impairment and Alzheimer's disease: a systematic review and meta-analysis.\nAbstract: Paired associative stimulation (PAS) is a non-invasive neuromodulation paradigm capable of inducing long-term potentiation (LTP)- or long-term depression (LTD)-like plasticity. It has been used to probe neuroplasticity and corticospinal excitability alterations in Alzheimer's disease (AD) and mild cognitive impairment (MCI). However, existing studies report inconsistent directions and magnitudes of PAS-induced plasticity changes across the AD continuum. We searched PubMed, Web of Science, Embase, and the Cochrane Library from database inception to December 2025. Eligible studies were case-control studies and randomized controlled trials (RCTs) that assessed PAS-induced cortical plasticity in individuals with AD or MCI, with healthy older adults as controls. Study quality was evaluated using the Newcastle-Ottawa Scale (NOS) for non-randomized studies and the Cochrane Risk of Bias tool (RoB 2) for RCTs. This review was registered in PROSPERO (CRD420251178441). Five studies met the inclusion criteria. Four studies quantified motor cortical plasticity using changes in motor-evoked potential (MEP) amplitude (total N = 135; 64 MCI/AD and 71 controls). The pooled analysis showed no significant difference in PAS-induced MEP changes between participants with MCI/AD and healthy controls [mean difference (MD) = 0.06, 95% CI (-0.05, 0.17), p = 0.32]. This pooled estimate was restricted to MEP-based outcomes and should be interpreted as an exploratory synthesis of motor-system readouts rather than definitive evidence of preserved cortical plasticity in MCI or AD. The remaining RCT, which assessed dorsolateral prefrontal cortex (DLPFC) plasticity using a repetitive PAS (rPAS) intervention without MEP outcomes, also found no significant improvement in prefrontal plasticity relative to control stimulation. Based on the currently available MEP-based evidence, PAS-induced motor-system plasticity findings in individuals with MCI or AD remain inconclusive. Given the limited number of studies and heterogeneity in experimental designs, the pooled negative results should not be interpreted as evidence that cortical plasticity is preserved. Corticospinal hyperexcitability and network-level PAS findings should be regarded as preliminary, hypothesis-generating observations requiring validation in larger, longitudinal, and biomarker-characterized cohorts.\n\nID: 42445281\nTitle: Advances in research on pharmacological mechanisms of anatabine: from nicotinic modulation to multitarget therapeutic potential.\nAbstract: Anatabine, a characteristic minor alkaloid derived from tobacco byproducts, exhibits unique structural analogy to nicotine but possesses a superior safety profile and lower addictive liability, rendering it a promising natural multi-target therapeutic candidate. Accumulating preclinical evidence has demonstrated that anatabine exerts neuroprotective, anti-inflammatory, and antioxidant effects mainly through modulating α7/α4β2 nicotinic acetylcholine receptors, suppressing NF-κB/STAT3 inflammatory signaling, and activating the Nrf2-mediated antioxidant pathway. It effectively ameliorates typical pathological alterations, including β-amyloid deposition, tau hyperphosphorylation, and microglial overactivation, thereby improving cognitive and behavioral deficits in neurodegenerative disease models. Additionally, anatabine displays broad pharmacological potentials in chronic inflammation, autoimmune thyroiditis, asthma, and hypertension. Differing from previous reviews that merely focused on single receptor regulation, the present work systematically summarizes the multi-target pharmacological characteristics of anatabine, comprehensively collates its preclinical efficacy across multiple disease categories, and highlights its advantages over nicotine in safety and addiction risk. Furthermore, we analyze the current limitations, druggability optimization challenges, and clinical translation prospects, and propose sustainable strategies for high-value utilization of tobacco byproducts. This review provides an updated and systematic theoretical basis for further mechanism exploration and therapeutic development of anatabine.\n\nID: 42445022\nTitle: High-Throughput CETSA Identifies Small Molecule Modulators of ILT3 (LILRB4) with Functional Activity in Human iPSC-Derived Microglia for Alzheimer's Disease.\nAbstract: Immune inhibitory signaling in microglia contributes to impaired amyloid-β (Aβ) clearance and neuroinflammation in Alzheimer's disease (AD), yet small molecule modulators targeting these pathways remain largely unexplored. Here, we report the development of a high-throughput cellular thermal shift assay (HT-CETSA) platform for identification of small molecule binders targeting the inhibitory immune receptor ILT3 (LILRB4). Screening of ∼40 000 compounds yielded multiple validated hits, including IB15C, a submicromolar ILT3 binder identified through preliminary structure-activity relationship optimization. Orthogonal validation by microscale thermophoresis, surface plasmon resonance, docking, and site-directed mutagenesis confirmed direct and target-specific ILT3 engagement. Functionally, IB15C disrupted the ILT3-ApoE interaction and restored microglial activity in human iPSC-derived microglia, reducing SHP1/2 and NF-κB signaling, suppressing IL-1β secretion, and enhancing Aβ uptake. IB15C also demonstrated favorable in vitro pharmacokinetic and safety properties, supporting further development of ILT3-targeted neuroimmune therapeutics.\n\nID: 42444987\nTitle: The amino acid substitutions A30W, K28A, and M35C alter amyloid-β peptide toxicity in cell culture and in an in vivo model of amyloidosis in Caenorhabditis elegans.\nAbstract: The buildup of toxic aggregates formed by the amyloid-β peptide 1-42 (Aβ42) is a central process in Alzheimer's disease (AD) pathology. The peptide's self-assembly and toxicity are highly dependent on its primary amino acid sequence and can be altered by modifying key residues. Specifically, the single amino acid substitutions A30W, K28A, and M35C can reduce the aggregation and toxicity of the Aβ42 peptide. In this study, we further evaluated the effects of these mutations in a C6 rat glioma cell line and in the Caenorhabditis elegans strains CL2006 and CL4176, which express muscular Aβ42 as an in vivo model. Our results showed that the A30W, K28A, and M35C substitutions reduce apoptosis induction in cell culture, in contrast to the WT Aβ42 peptide. In C. elegans, the three variants extended the lifespan of CL2006 worms by reducing fibrillar aggregates or altering aging, whereas the M35C peptide delayed the paralysis of CL4176 worms. Additionally, the substitutions altered oxidative stress and autophagy in control worms. Taken together, these results suggest that the A30W, K28A, and M35C substitutions reduce Aβ42 toxicity in cell culture and in C. elegans and could protect the nematode against Aβ42 toxicity.\n\nID: 42444752\nTitle: Anti-amyloid nanobody-Fc fusion protein drives potent amyloid clearance through microglial recruitment.\nAbstract: Anti-amyloid beta (Aβ) monoclonal antibodies are effective at lowering amyloid in Alzheimer's disease (AD). However, whether Fc-mediated effector function is absolutely required for efficacy is not completely understood. This is important for optimizing therapeutic efficacy and mitigating side effects such as amyloid-related imaging abnormalities (ARIA). Antibodies lacking Fc effector function, like single-domain antibodies (nanobodies), offer a unique tool to dissect these mechanisms, as their small size facilitates blood-brain barrier (BBB) penetration and allows Fc-mediated functions to be studied independently. We immunized a llama with Aβ aggregates and constructed a phage display library to screen for aggregate-specific nanobodies. Lead candidates were characterized by epitope mapping and binding affinity to amyloid plaques in both murine and human AD brain tissues. We further assessed their BBB permeability and evaluated their efficacy in clearing pre-existing plaques in amyloid precursor protein (APP)/presenilin 1 (PS1) mice. We identified two lead nanobodies, 3A11 and 2D10, that bind distinct epitopes and specifically bind Aβ plaques in murine and human AD brain tissues. Following systemic administration, the monovalent, unmodified (Fc-less) 2D10 nanobody, but not 3A11, successfully crossed the BBB and engaged amyloid plaques in APP/PS1 mice. However, despite robust target engagement, the Fc-less 2D10 failed to recruit microglia or reduce plaque burden. In contrast, an engineered 2D10-Fc fusion antibody potently cleared amyloid plaques, achieving a reduction in pathology comparable to aducanumab treatment. This efficacy was directly correlated with Fc-mediated microglial recruitment and activation, demonstrating that the Fc domain is essential for phagocytic plaque removal. Our findings demonstrate that Fc effector function is indispensable for microglial-mediated amyloid clearance in vivo. By clarifying this fundamental mechanism, this study provides a framework for the rational design of next-generation immunotherapies. Furthermore, 2D10-Fc represents a promising therapeutic candidate, combining the high-affinity targeting of nanobodies with the effector power necessary for robust plaque clearance.\n\nID: 42444751\nTitle: Heterogeneous responses to memantine in Alzheimer's disease: A precision medicine approach using iPSC models.\nAbstract: Alzheimer's disease (AD) is a complex neurodegenerative disorder characterized by progressive cognitive and functional decline. Memantine, a commonly prescribed N-methyl-D-aspartate receptor antagonist, appears to slightly delay symptom progression in moderate or advanced stages of AD. Clinical response is highly variable across patients with some benefiting but others not. Induced pluripotent stem cell (iPSC)-derived neurons can provide a donor-dependent model to predict the therapeutic efficacy of memantine. We generated iPSC-derived cortical neurons from 19 individuals (12 AD and 7 cognitively unimpaired [CU]). Assays for calcium influx and oxidative stress were developed and optimized for neurons. Memantine was tested under different treatment conditions. Neurons were exposed to glutamate/glycine to induce calcium influx and menadione to generate oxidative stress. Memantine treatment was applied either acutely (1 hour) or as a 24-hour pre-treatment to evaluate its neuroprotective effects. Peripheral blood mononuclear cell-derived iPSCs were successfully differentiated into functional neurons, exhibiting comparable electrophysiological properties between AD and CU lines. Calcium influx assays revealed a heterogeneous response among AD and CU neurons, with AD neurons generally displaying higher baseline fluorescence. Memantine treatment for 24 hours significantly reduced calcium influx, with a -9.85% average reduction and a range of -0.39% to -39%. Similarly, reactive oxygen species assays showed menadione-induced oxidative stress was attenuated by 24-hour memantine pre-treatment for a mean -26.05% reduction and a range of -4.23% to -72.21%. The observed variability indicates differential susceptibility to excitotoxicity reduction and or oxidative stress mitigation across lines. This exploratory study establishes a robust in vitro platform to test memantine efficacy using iPSC-derived neurons to model calcium dysregulation and oxidative stress in AD. The observed variability in response highlights the importance of personalized approaches in AD treatment, emphasizing the potential for iPSC-based platforms in precision medicine.\n\nID: 42444728\nTitle: Associations among mild behavioral impairment, cognition, and brain pathology in preclinical autosomal dominant Alzheimer's disease.\nAbstract: The Mild Behavioral Impairment Checklist (MBI-C) captures neuropsychiatric symptoms in individuals at risk of dementia. In this study, we examined MBI-C scores in autosomal dominant Alzheimer's disease (ADAD). We included 83 cognitively unimpaired presenilin-1 E280A mutation carriers and 114 non-carriers with MBI-C, obfjective cognition, and subjective cognitive decline (SCD) assessments. Study sub-samples underwent neuroimaging to assess Alzheimer's disease (AD) pathology and neurodegeneration. MBI-C total scores were greater in carriers than non-carriers (r rb = 0.19 [95% confidence interval (CI) 0.05, 0.31], P = 0.009), driven by impulse dyscontrol symptoms. Elevated MBI-C scores were associated with higher study partner-reported SCD scores (β = 0.28 [95% CI 0.07, 0.050], P = 0.008) and with greater neocortical amyloid beta (β = 0.46 [95% CI 0.17, 0.075], P = 0.003) among carriers. Our study reveals that mild behavioral impairment symptoms may emerge before cognitive decline in ADAD and supports the MBI-C as a tool for detecting early behavioral changes linked to AD pathology and identifying at-risk individuals for clinical trials and early intervention.\n\nID: 42444486\nTitle: Branched-chain amino acids and gut microbiota: coregulation and impact on neurological function via the gut-brain axis.\nAbstract: Diseases that cause neurological dysfunction, such as Parkinson's disease (PD), Alzheimer's disease (AD), and maple syrup urine disease (MSUD), among others, are characterized by complex and multifaceted etiologies. There is growing evidence that branched-chain amino acids (BCAAs), regulated by the gut microbiota, play a critical role in the development of the central nervous system (CNS) disorders. This review focuses on the potential role of branched-chain amino acid metabolism in regulating brain function and gut microbiota. First, we summarize the current understanding of BCAAs, encompassing their biochemical metabolism, function, and systemic metabolic mechanisms. Subsequently, we delve into the mechanisms through which the gut microbiota regulates branched-chain amino acid metabolism, along with its mechanistic insights and recent evidence of its impact on neurological disorders. Finally, we discuss future research directions and challenges regarding gut BCAAs metabolism as a potential treatment for brain and gastrointestinal dysfunction.\n\nID: 42444329\nTitle: Young Adult Microglial Deletion of C1q Reduces Engulfment of Synapses and Partially Mitigates Cognitive Impairment in an Aggressive Alzheimer's Disease Mouse Model.\nAbstract: C1q is a multifunctional protein, including its role as the initiating protein of the classical complement cascade. While classical pathway activation is involved in synaptic pruning during nervous system development, it also contributes to inflammation and cognitive decline in Alzheimer's disease (AD). Constitutive genetic C1q deficiency has been shown to reduce glial activation and attenuate neuronal loss in AD mouse models, but the specific contributions of microglial C1q to AD pathology while avoiding deficits during post-natal development remain unaddressed. To dissect specific role(s) of microglial C1q in AD progression, we crossed the Cx3cr1CreERT2 mouse model that deletes C1q from microglia in young adulthood (8 weeks of age) to the aggressive Arctic48 (Arc) amyloidosis mouse model. At 10 months, young adult microglial C1q deletion (Arc C1qΔMG) was associated with improved spatial memory performance, despite unchanged amyloid plaque burden. Furthermore, Arc C1qΔMG mice exhibited reduced hippocampal C3 protein levels without altering C3 mRNA. No changes were observed in C5aR1, astrocyte GFAP, or microglial Iba1 protein expression. However, Arc C1qΔMG mice demonstrated region specific reductions in microglial synaptic engulfment, alongside decreased phagolysosome-associated amyloid in both microglia and astrocytes, and reduced hippocampal amyloid compaction. These findings support a role for C1q in astrocytic C3 induction and the engulfment of both synapses and amyloid. Importantly, young adult microglial C1q inhibition confers cognitive benefits without exacerbating amyloid pathology, suggesting a therapeutic window in which targeting microglial C1q may help preserve synaptic integrity and modulate the neuroinflammatory processes during the later stages of AD.\n\nID: 42444286\nTitle: Vascular-Apoptotic Crosstalk in Alzheimer's Disease: The Possible Role of Vascular Senescence in Blood-Brain Barrier Dysfunction.\nAbstract: Blood-brain barrier (BBB) dysfunction is an early feature of Alzheimer's disease (AD), influenced by amyloid pathology, astrocyte activation, and vasoactive mediators such as endothelin-1 (ET-1). ET-1 has been implicated in apoptosis and vascular senescence through induction of p53, a pro-apoptotic factor, whereas BCL-X exerts antiapoptotic effects. We investigated the interplay between ET-1, p53, and BCL-X in AD and their contribution to BBB permeability. We studied 101 individuals (70 AD, 31 controls) who underwent cerebrospinal fluid (CSF) analysis for Aβ42, p-tau, ET-1, p53, BCL-X, and the CSF/serum albumin quotient (QAlb), an index of BBB permeability. Correlations between biomarkers were explored, followed by multiple regression and mediation analysis to assess whether p53 mediated the ET-1-BBB relationship. No absolute differences in ET-1, p53, or BCL-X were found between AD and controls. However, in AD, ET-1 correlated positively with p53 and negatively with BCL-X, whereas no such associations were seen in controls. None of these biomarkers related to the p-tau/Aβ42 ratio. Regression analysis identified both ET-1 and p53 as independent predictors of BBB permeability. Mediation analysis further revealed that ET-1 influenced BBB permeability both directly and indirectly through p53. Our findings suggest that AD is characterized less by absolute biomarker changes and more by altered interrelationships linking ET-1, apoptosis, and BBB integrity. ET-1 may promote BBB dysfunction partly via p53, which is consistent with the mechanisms of vascular senescence. These results highlight apoptosis-vascular interactions as potential drivers of BBB impairment in AD.\n\nID: 42444063\nTitle: EXPRESS: Ultrasound Enhances Glymphatic-Associated Solute Transport via Piezo1-Related Mechanotransduction in 5xFAD Mice.\nAbstract: Glymphatic dysfunction impairs Aβ clearance and contributes to Alzheimer's disease (AD) progression. Low-intensity transcranial focused ultrasound (LITFUS) can enhance glymphatic cerebrospinal fluid transport, but its therapeutic effects on Aβ clearance and cognitive decline remain unclear. 5xFAD mice received bilateral hippocampal LITFUS for 4 weeks. Glymphatic transport was assessed by fluorescent tracer injection and ex vivo imaging. Aβ deposition, Iba1 immunoreactivity, and cognitive function were evaluated by immunohistochemistry and behavioral tests. Piezo1 involvement was examined using GsMTx4, qPCR, and Western blotting of isolated brain vascular fractions. Safety was assessed by blood-brain barrier permeability and H&E staining. LITFUS increased brain-wide CSF tracer influx and hippocampal interstitial solute clearance in 5xFAD mice. It reduced Aβ deposition in the hippocampus and prefrontal cortex, decreased Iba1 immunoreactivity, and improved learning and memory. These effects were associated with increased Piezo1 expression and enhanced CaMKII/eNOS signaling in brain vascular fractions, and were attenuated by GsMTx4. No blood-brain barrier disruption or histological injury was detected. LITFUS enhances glymphatic transport, reduces cerebral Aβ burden, and improves cognition in 5xFAD mice, possibly through Piezo1-related mechanotransduction, supporting its potential as a noninvasive AD therapy.\n\nID: 42443969\nTitle: Breaking the glial loop: astrocytic PAD2 and citrullinated vimentin drive microglial dysfunction in Alzheimer's disease.\nAbstract: Zhang et al. reveal that astrocytic PAD2-mediated citrullination of vimentin drives a TLR4-dependent pro-inflammatory loop in microglia, linking glial crosstalk to impaired amyloid clearance and identifying a potential therapeutic and biomarker pathway in Alzheimer's disease.\n\nID: 42443967\nTitle: Microglial mitophagy as an immunometabolic checkpoint in alzheimer's disease: linking mitochondrial quality control to neuroinflammation.\nAbstract: AD is a complex neurodegenerative disorder characterized by chronic neuroinflammation. Microglia, the brain's resident immune cells, centrally regulate AD pathophysiology. Recent studies have highlighted microglial mitophagy as an important interface linking mitochondrial quality control to innate immune responses.Intact mitophagy facilitates the timely clearance of damaged mitochondria, thereby limiting the release of mitochondrial DAMPs (e.g., mtDNA and mtROS) and helping restrain aberrant activation of the cGAS-STING pathway and the NLRP3 inflammasome.In the AD pathological milieu, however, factors including Aβ deposition, tau pathology, and genetic risk variants such as TREM2 and APOE4 disrupt mitophagy at multiple levels-from initiation and recognition to lysosomal degradation. This review systematically summarizes the molecular regulatory network of microglial mitophagy, with a particular focus on the mechanisms by which AD-associated pathological factors impair this process. We further discuss potential mechanisms through which mitophagic dysfunction may contribute to the amplification of neuroinflammation, including the release of mitochondrial DAMPs, the reprogramming of TBK1 signaling, and intercellular interactions. Finally, we outline current therapeutic strategies aimed at restoring mitophagy and discuss their potential to modulate neuroinflammatory responses and AD-related pathological processes, while highlighting the challenges and future directions in this emerging field.\n\nID: 42443581\nTitle: Rethinking blood-brain barrier permeability in Alzheimer's disease: insights from APOE genotype-specific associations.\nAbstract: \n\nID: 42443567\nTitle: Standardized Extract of Ginkgo biloba L. Reverses Memory Impairment in Older Female Mice with Basal Forebrain Cholinergic Dysfunction.\nAbstract: Aging induces neurochemical changes, particularly in the dentate gyrus (DG), that impair memory. In late-onset Alzheimer's disease (LOAD), neuronal loss in regions like the entorhinal cortex (EC) and hippocampus proper (HP), along with amyloid-β (Aβ) plaques, tau tangles, and reduced cholinergic signaling, accelerates cognitive decline. Building on our group's previous findings of cognitive benefits and neuroprotection from Ginkgo biloba L. leaf extract (EGb), and considering the limited success of current therapies, EGb has emerged as a promising multi-target strategy for reversing memory impairments. This study evaluates the effects of chronic EGb treatment on memory, anxiety-like behaviors, and motor activity in older female wild-type and VAChT knockdown KDHET and KDHOM mice, which show 45% and 65% reductions in VAChT expression, respectively. We assessed the impact of EGb on Aβ1-42 peptide and phosphorylated tau (pTauT231) by quantifying Aβ IR+ and pTau IR+ cells in the dCA1, dCA3, and dDG, via immunohistochemistry. Results showed that aging led to short- and long-term memory deficits, which were exacerbated in the VAChT KDHOM mice. However, EGb treatment reversed these deficits in a dose-dependent manner by modulating Aβ and pTau-IR+ cells in the dCA1, and dDG regions. In vitro, EGb significantly inhibited Aβ aggregation through interactions with Aβ and the POPC monolayer. These findings suggest that EGb may provide a promising therapeutic strategy for AD, improving cognition and offering neuroprotection by targeting key neuropathological features like Aβ plaques and phosphorylated tau.\n\nID: 42443390\nTitle: PIAS1-mediated GSK3β SUMOylation exacerbates tauopathy and cognitive deficits in Alzheimer's disease models.\nAbstract: Age-related neurodegenerative disorders, such as Alzheimer's disease (AD), are characterized by the accumulation of pathological Tau protein (tauopathy), which drives neurotoxicity and cognitive decline. Although SUMOylation significantly influences tauopathy, the underlying mechanisms remain largely elusive. Here, utilizing a bimolecular fluorescence complementation (BiFC) assay to monitor Tau-Tau aggregation and screen for SUMO E3 ligases, we identified PIAS1 as a critical driver of Tau pathology. Genetic analysis of the UK Biobank cohort revealed that single nucleotide polymorphisms in the PIAS1 gene (rs8036154 and rs112677781) are significantly associated with a reduced risk of AD. Consistent with this clinical relevance, PIAS1 expression is upregulated in postmortem AD brains, aging PS19 tauopathy mice, aged wild-type mice, aged lemurs, and neurons stimulated with amyloid-beta or lipopolysaccharide. Viral-mediated modulation of PIAS1 in vivo demonstrated that PIAS1 promotes Tau hyperphosphorylation and aggregation, thereby exacerbating synaptic dysfunction and cognitive deficits. Mechanistically, we found that PIAS1 directly interacts with and mediates the SUMOylation of glycogen synthase kinase 3 beta (GSK3β) at lysine residues 183 and 271. This specific SUMOylation reduces inhibitory phosphorylation at Ser9, consequently enhancing GSK3β-mediated Tau kinase activity. Importantly, we engineered a cell-permeable blocking peptide designed to disrupt the PIAS1-GSK3β interaction. Administration of this peptide effectively suppressed GSK3β activation and mitigated tauopathy and neurodegeneration in both in vitro and in vivo models. Together, our findings uncover a novel PIAS1-GSK3β signaling axis in tauopathy and provide a promising targeted therapeutic strategy for Alzheimer's disease.\n\nID: 42442919\nTitle: Therapeutic targeting of brain bioenergetics in Alzheimer's disease addressing insulin resistance, glucose hypometabolism, and mitochondrial dysfunction.\nAbstract: Alzheimer's disease (AD) is a progressive, age-associated multifactorial neurodegenerative disorder characterised by cognitive decline, synaptic dysfunction, and neuronal loss. Despite over a century of research, effective disease-modifying therapies remain elusive owing to its conundrum pathophysiology. In recent years, AD is increasingly recognised as a complex metabolic disorder characterised by impaired cerebral glucose metabolism, insulin resistance, and mitochondrial dysfunction. These interconnected metabolic disturbances emerge early in the disease state and collectively potentiate other pathologies such as accumulation of amyloid-β (Aβ) plaques, tau hyperphosphorylation, oxidative stress, neuroinflammation, and synaptic dysfunction, thereby establishing bioenergetic failure as a primary factor governing AD progression rather than a downstream phenomenon. While traditional drug development strategies targeting Aβ have failed in clinical trials (limited to monoclonal antibodies), emerging therapeutic models integrating energy failure, thiamine signalling, and insulin-like growth factor (IGF) signalling as upstream events show significant promise in countering downstream neurodegeneration. This chapter summarises the mechanistic framework linking bioenergetic breakdown to AD pathology, with potential therapeutic opportunities aimed at restoring mitochondrial function, enhancing glucose utilisation, and correcting insulin signalling, further opening new avenues for multimodal interventions and identification of progressive metabolic dysfunction biomarkers to aid diagnostic processes.\n\nID: 42442918\nTitle: Insulin resistance and obesity: Drivers of energy crisis for Alzheimer's disease.\nAbstract: Alzheimer's disease (AD) is increasingly recognized as a disorder driven not only by classical neuropathological hallmarks but also by profound disturbances in brain energy metabolism. Growing evidence points to insulin resistance and obesity as major contributors to this metabolic crisis, linking peripheral metabolic dysfunction to central neurodegenerative processes. This chapter explores AD in the light of bioenergetic failure, highlighting the epidemiological and mechanistic connections between impaired insulin signaling, excess adiposity, and cognitive decline. The chapter further highlights how obesity-related inflammation, adipokine imbalance, and gut-brain axis dysregulation accelerates central insulin resistance and neuronal vulnerability. Evidence for glucose hypometabolism, mitochondrial failure, and disrupted astrocyte-neuron metabolic coupling in AD is reviewed, positioning amyloid and tau pathology as downstream consequences of sustained energy insufficiency. Finally, emerging therapeutic strategies aimed at restoring metabolic balance ranging from insulin-based interventions to lifestyle and mitochondria-targeted approaches are discussed, underscoring the potential of metabolic restoration as a disease-modifying strategy in Alzheimer's disease.\n\nID: 42442916\nTitle: Metabolic drivers of Alzheimer's disease pathogenesis: Impairments in glucose utilization, lipid homeostasis, and alternative substrate metabolism.\nAbstract: Alzheimer's disease (AD) is one of the widespread neurodegenerative disorders, marked by the accumulation of amyloid-β plaques, neurofibrillary tangles of hyperphosphorylated Tau protein, and the gradual loss of neurons. While genetic and environmental factors have been associated with its onset, metabolic dysfunction has also been identified as one of the initial and most significant contributors its pathogenesis. The mitochondria are at the centre of this problem; their compromised function affects some crucial aspects of the neuronal health. Neurons have high energy demands so they are quite sensitive to the changes in the supply of the fuel. During AD pathogenesis, the loss of glucose transporters and the downregulation of key glycolytic enzymes deprives neurons of essential energy reserve. This metabolic dysregulation is further exacerbated by dysregulated lipid metabolism, pathological lipid droplet accumulation and ApoE4-driven failures in lipid trafficking which collectively leads to the oxidative stress, neuroinflammation, and Aβ aggregation. This situation is further aggravated by amino acid imbalances specifically within the glutamate-glutamine cycle. To counter this, ketone bodies have emerged as an alternative fuel source, capable of partially bypassing the impaired glucose oxidation while also demonstrating neuroprotective properties. Moreover, systemic metabolic disorders including type 2 diabetes mellitus, insulin resistance, obesity, and metabolic syndrome significantly amplify these deficits, functioning as major risk factors for AD onset and progression. Even the gut-brain axis plays a role in adding to the complexity. Taken together, these metabolic health changes not only reshape our understanding of AD but also open potential prospects for early detection through metabolic biomarkers and for novel therapeutic strategies targeting mitochondrial bioenergetics, glucose restoration, and ketogenic interventions.\n\nID: 42442914\nTitle: Metabolic reprogramming in Alzheimer's disease: Interaction between receptor tyrosine kinase signaling, noncoding RNAs, and Neuron-Glia energy networks.\nAbstract: Alzheimer's disease (AD) is increasingly understood as a disorder involving impaired brain energy metabolism rather than being solely caused by amyloid and tau pathology. This chapter offers a comprehensive overview of how glucose hypometabolism, mitochondrial dysfunction, and disrupted neuron-astrocyte metabolic coupling collectively creates an \"energy crisis\" in vulnerable neuronal circuits. Early issues with glucose transport (GLUT1/3/4), reduced glycolytic flux, TCA cycle problems, and excessive mitochondrial fission all contribute to decreased ATP production and increased oxidative stress. Along with these metabolic disturbances, receptor tyrosine kinase (RTK) pathways-including insulin/IGF-1, TrkB/BDNF, FGFRs, and EGFR-lose their regulatory control, leading to insulin resistance, synaptic failure, and increased vulnerability to Aβ and tau toxicity. The chapter also highlights noncoding RNAs (miRNAs and lncRNAs) as key post-transcriptional regulators of metabolic and RTK signaling networks. Harmful miRNAs (such as miR-34a, miR-210-3p) suppress glycolytic enzymes and mitochondrial genes, while protective miRNAs (miR-23a/b, miR-455-3p, miR-195) decrease in AD. Metabolic lncRNAs, like EPB41L4A-AS1, decline with age and contribute to NAD⁺ depletion and bioenergetic imbalance. Recognizing the link between RTK dysregulation and ncRNA-driven metabolic control reveals new therapeutic possibilities to restore mitochondrial function, enhance neurotrophic support, and re-establish energy balance in the AD brain.\n\nID: 42444591\nTitle: Self-Assembly of Antigenic Peptide Nanofibrils Templates the Growth of Silica Nanoparticles for Nanovaccines.\nAbstract: The low immunogenicity of peptide vaccines remains a critical challenge in immunotherapy. While peptide nanofibrils can function as self-delivery systems to activate antigen-presenting cells (APCs), most existing designs rely on complex covalent conjugation to β-sheet-forming motifs. Moreover, the diverse surface properties of various antigenic peptides complicate the rational selection of appropriate adjuvants. Herein, we develop a nanovaccine platform in which antigenic peptides self-assemble into nanofibrils without the need for exogenous β-sheet-forming sequences. Silica nanoparticles (SiO2 NPs) are nucleated and grown directly along these fibrils, resulting in SiO2@fibril nanovaccines with a unique \"beads-on-a-string\" morphology. Using amyloid-β(1-42) (Aβ42) and human papillomavirus (HPV) type 16 E7 (E7) as model antigens, we demonstrate that these nanovaccines significantly enhance the maturation and activation of bone marrow-derived dendritic cells (BMDCs). In an Alzheimer's disease animal model using APP/PS1 mice, SiO2@Aβ42 nanovaccines improve motor and cognitive function. Additionally, in an HPV animal model using TC-1 tumor-bearing mice, SiO2@E7 nanovaccines suppress tumor growth and increase survival rate. This strategy provides a universal and modular adjuvant platform for peptide-based nanovaccines.\n\nID: 42444503\nTitle: A First-In-Class Antibody Enabling Detection of Altered Peripheral Non-Phosphorylated Clusterin With Translational Potential in Dementia.\nAbstract: Clinical diagnosis of dementia, with Alzheimer's disease (AD) as the major form, relies heavily on memory tests and the caregiver descriptions, both of which are subjective. The discovery of reliable biomarkers may facilitate objective diagnosis. The protein clusterin (CLU), encoded by a well-established AD risk gene, is consistently elevated in AD patients, but its biomarker utility is limited by high interindividual variability. As CLU is produced in most organs and tissues, quantifying CLU secreted specifically from the brain into the bloodstream may help the development of new diagnostic methods. CLU in blood can be phosphorylated at T393-S394 and/or S396, but these phosphorylations are absent in brain parenchyma. Peripherally administered non-phosphorylated CLU has been shown to reduce neuroinflammation and AD pathology in mouse models. A monoclonal antibody, 3D3F10, targeting non-phosphorylated CLU at T393-S394 or S396 was generated. This antibody showed an ability to distinguish serum samples of dementia and non-dementia (p < 0.001, AUC = 0.897, sensitivity: 81.8%, specificity: 95.5%, Youden index: 0.77), but did not distinguish Parkinson's disease. The direction of the change contradicted our initial hypothesis, and further analyses suggested that phospho-CLU in dementia patients is unlikely to originate from the brain. These results established 3D3F10 as a novel tool for modification-specific CLU detection, indicated a potential of non-phospho-CLU as a biomarker for dementia, and peripheral phospho-CLU might play a role in pathogenesis.\n\nID: 42443949\nTitle: CIT-Lasso: a scalable approach beyond guilty by association for identifying causal variants from genome-wide summary statistics.\nAbstract: We present CIT-Lasso, a framework that uses only summary statistics to identify, genome-wide, sets of variants carrying non-redundant information on a phenotype, distinguishing likely causal variants from correlated variants that are merely associated. The open-source implementation completes genome-wide analysis in under 15 min on one CPU. In simulations, it outperforms existing methods in false discovery rate control, power, and fine-mapping resolution. Applied to an Alzheimer's disease meta-analysis, it identified 82 loci, 37 beyond conventional GWAS; prior MPRA and CRISPR-Cas9 studies corroborate prioritized variants. Results on other 67 large-scale GWAS reveal the method's generalizability to make discoveries beyond conventional GWAS pipeline.\n\nID: 42442917\nTitle: Glial molecular signatures as a liquid biopsy marker in Alzheimer's disease diagnosis.\nAbstract: Alzheimer's disease (AD) is a neurodegenerative condition that is characterized by the misfolding of Amyloid Precursor Protein, hyperphosphorylation of tau protein, and neuroinflammation. This leads to the formation of extracellular senile amyloid beta plaque and neurofibrillary tangles in neurons, leading to neuronal degeneration. AD is the biggest cause of dementia globally. Currently, no therapies are available for AD and early diagnosis of the disease is a challenge. The most common fluid biomarkers for AD are: p-tau181, p-tau231, p-tau217, Aβ42/Aβ40 ratio, Neurogranin (Ng), Alzheimer's-associated neuronal thread protein (AD7c-NTP). All these biomarkers are detected in Blood, CSF, Saliva, and Urine with the help of different assays, PET scan, and MRI Imaging. These biomarkers are of neuronal origin and indicate neuronal stress. Brain also contains glial cells along with the neurons, which interact with the neurons in health and disease conditions. These glial cells also release molecules in disease induced stress. These markers can be used for early and differential diagnosis of AD and other dementia conditions. Studies also show that these glia biomarkers are released decades before the actual neuron degeneration begins. In this review, we will discuss these glial cells biomarkers identified in liquid biopsy for AD detection and progression.\n\nID: 42442566\nTitle: Sleep-Related Alzheimer's Disease Vulnerability in Aging: A Muscle-Metabolic Perspective.\nAbstract: Sleep disruption is a hallmark of aging and a plausible driver of Alzheimer's disease vulnerability. Reduced slow-wave sleep, increased fragmentation, and circadian instability may facilitate amyloid-β accumulation, tau propagation, neuroinflammation, oxidative stress, and impaired glymphatic clearance. Yet the physiological factors that predispose older adults to unstable sleep remain insufficiently integrated into models of brain aging. This Review advances a sleep-muscle-brain framework in which sarcopenia, sarcopenic obesity, and insulin resistance are conceptualized as modifiable muscle-metabolic conditions that may bias sleep continuity and shape the biological impact of sleep disruption. We examine irisin/FNDC5-BDNF signaling as a hypothesis-generating candidate modifier of metabolic regulation, neurotrophic support, and brain resilience, while emphasizing that direct evidence for a causal role in human sleep regulation remains insufficient. Irisin-related pathways intersect with insulin sensitivity, inflammatory control, and BDNF-dependent synaptic plasticity, all of which are relevant to the physiological context in which sleep disruption may influence Alzheimer's disease pathophysiology. We propose that age-related attenuation of muscle endocrine signaling, together with insulin resistance and low-grade inflammation, may lower the threshold at which sleep fragmentation translates into amyloid/tau dyshomeostasis, glial activation, and network dysfunction. Rather than treating sleep disturbance as an isolated brain-centered risk factor, this framework positions sleep as a biobehavioral hub through which peripheral aging processes can modulate neurodegenerative resilience. The Review integrates evidence from sleep neuroscience, geroscience, metabolism, and neurodegeneration, and identifies experimentally testable predictions. A sleep-muscle-brain perspective may help refine risk stratification and guide multimodal interventions combining sleep optimization, resistance exercise, metabolic targeting, and Alzheimer's disease biomarker monitoring.\n\nID: 42441681\nTitle: [Social Cognition and Theory of Mind as a Differential Marker Between Alzheimer's Disease and Behavioral Variant Frontotemporal Dementia].\nAbstract: While language, memory, and executive function have been proposed as differential markers between Alzheimer's disease (AD) and behavioral variant frontotemporal dementia (bvFTD), recent studies emphasize the role of Social Cognition (SC) and Theory of Mind (ToM) in distinguishing between these conditions. To characterize SC and ToM performance in patients with AD and bvFTD. This review followed PRISMA guidelines and included studies published between January 2015 and March 2024 from PubMed, Scopus, and Web of Science. Fourteen studies were critically analyzed. Findings suggest that SC and ToM are impaired in both disorders. In AD, the main deficits involve emotional recognition and perception, and social behavior. In bvFTD, common impairments include decision-making, emotion recognition, social behavior, and empathy loss. SC and ToM may support the differential diagnosis between AD and bvFTD, particularly in early stages. Further research is needed to develop standardized assessments for clinical use to detect and classify the severity of SC and ToM decline.\n\nID: 42441363\nTitle: Longitudinal changes in DTI-ALPS and choroid plexus volume relative to CSF biomarkers during lecanemab treatment in mild cognitive impairment: A pilot study.\nAbstract: Lecanemab improves cerebrospinal fluid (CSF) biomarkers, but whether magnetic resonance imaging (MRI) proxies of CSF-interstitial fluid (ISF) exchange improve is unknown. This was a single-center prospective pilot (n = 8). The ALPS index was derived from diffusion tensor image analysis along the perivascular space (DTI-ALPS), and intracranial volume (ICV)-normalized choroid plexus (ChP) volume was segmented with FreeSurfer Sequence Adaptive Multimodal SEGmentation (SAMSEG). Baseline changes were tested with Wilcoxon signed-rank tests with Benjamini-Hochberg false discovery rate (FDR) control within prespecified MRI, CSF, and cognition endpoint families. CSF Aβ42 and Aβ42/40 increased and tau phosphorylated at threonine 181 (p-tau181) decreased at 6 and 12 months (all q < 0.05); cognition showed no FDR-significant change. The ALPS index showed a downward tendency (9-month q = 0.010), and ChP/ICV increased at 6-12 months (all q = 0.010). The ALPS index and ChP volume may be insufficient as stand-alone surrogate endpoints over 12 months. These findings suggest exploring complementary strategies targeting CSF-ISF exchange and clearance pathways and warrant larger controlled longitudinal studies. Not applicable (observational study).\n\nID: 42440686\nTitle: Comparison of safety of lecanemab and donanemab: a real-world disproportionality analysis using the FDA adverse event reporting system.\nAbstract: Lecanemab and donanemab are anti-amyloid-β (Aβ) monoclonal antibodies recently approved for the treatment of Alzheimer's disease (AD). Although both agents have demonstrated therapeutic potential, their post-marketing adverse event reporting profiles remain insufficiently characterized and compared in spontaneous reporting systems. This study aimed to systematically compare adverse event signals associated with these two drugs using the FDA Adverse Event Reporting System database, with sex-stratified and sensitivity analyses performed to support the main findings. FAERS reports up to the fourth quarter of 2025 were retrospectively analyzed. Reports in which lecanemab or donanemab was recorded as the primary suspect drug were included. AEs were classified by system organ classes (SOCs) and preferred terms (PTs) according to the Medical Dictionary for Regulatory Activities (MedDRA). Signal detection was performed using four algorithms: reporting odds ratio (ROR), proportional reporting ratio (PRR), Bayesian confidence propagation neural network (BCPNN), and multi-item gamma Poisson shrinker (MGPS). Sex-stratified analysis, sensitivity analysis after excluding reports involving concomitant medications, and time-to-onset (TTO) analysis based on the Weibull shape parameter model were also conducted. False discovery rate (FDR) correction was applied to analyses involving multiple P values. A total of 3,640 AE reports were identified, including 2,602 for lecanemab and 1,038 for donanemab. Nervous system disorders was the most frequently reported SOC and the only SOC meeting the positivity criteria across all four algorithms for both drugs. At the PT level, the frequently reported events for both drugs were mainly concentrated in amyloid-related imaging abnormality (ARIA)-related events, including ARIA with oedema/effusion (ARIA-E) and ARIA with microhaemorrhages/haemosiderin deposition (ARIA-H), headache, and infusion-related reactions. The strongest disproportionality reporting signals were mainly observed for ARIA-related preferred terms and cerebral microhaemorrhage. In separate FAERS-based disproportionality analyses, lecanemab showed stronger disproportionality reporting signals for ARIA-H, whereas donanemab showed stronger disproportionality reporting signals for ARIA-E. In addition, drug-specific PT signal distributions differed between the two agents. Several potential novel PT signals were also identified. Sex-stratified analysis suggested differences in the distribution of certain PT signals between female and male reports. Sensitivity analysis supported the stability of most core signals. The median TTO was 46 days for lecanemab and 31 days for donanemab, and Weibull analysis suggested different temporal patterns of AE occurrence. Using four signal detection algorithms, this study compared real-world adverse event reporting profiles associated with lecanemab and donanemab. The two drugs showed both shared and distinct adverse event reporting profiles, particularly in ARIA subtype-related disproportionality signals, drug-specific PT signals, potential novel reporting signals, sex-stratified reporting patterns, and TTO characteristics. These findings provide pharmacovigilance evidence for targeted safety monitoring and hypothesis generation, but should not be interpreted as causal associations or true incidence estimates.\n\nID: 42440665\nTitle: The latest research progress of ligustilide in the prevention and treatment of central nervous system disorders.\nAbstract: Ligustilide (LIG), a natural phthalide compound mainly isolated from Angelica sinensis and Ligusticum chuanxiong, has attracted increasing attention because of its diverse pharmacological activities, including anti-inflammatory, antioxidant, anti-apoptotic, and neuroprotective effects. Emerging studies suggest that LIG may have therapeutic relevance in central nervous system (CNS) disorders. This review systematically summarizes the pharmacological effects, molecular mechanisms, pharmacokinetic characteristics, metabolism, safety profile, and therapeutic potential of LIG in CNS disorders. Relevant studies published up to 26 October 2025 were retrieved from PubMed, Web of Science, and Scopus using keywords related to ligustilide, central nervous system disorders, pharmacokinetics, metabolism, and toxicity. After removing duplicate records and excluding reviews, editorials, and irrelevant articles, 55 eligible original studies were included in this review. Current evidence indicates that LIG exerts neuroprotective effects in multiple CNS disorders, including ischemic stroke, cerebral ischemia-reperfusion injury, vascular dementia, Alzheimer's disease, Parkinson's disease, traumatic brain injury, and anxiety disorders. Its mechanisms mainly involve modulation of PI3K/Akt, MAPK, NF-κB, Nrf2/ARE, AMPK, and other signaling pathways, leading to reduced oxidative stress, inflammation, apoptosis, and mitochondrial dysfunction. In addition, available studies suggest that LIG can cross the blood-brain barrier and shows relatively favorable safety in preclinical models. LIG demonstrates broad neuroprotective potential in preclinical studies and may represent a promising candidate for CNS disease intervention. However, its poor chemical stability, low oral bioavailability, limited toxicity evaluation, and lack of clinical evidence remain major challenges for translational application. Further studies are required to optimize delivery strategies and validate its efficacy and safety in clinical settings.\n\nID: 42439681\nTitle: Rethinking Anti-Inflammatory Therapy in Alzheimer's Disease: From Broad Suppression to Stage-State-Space Neuroimmune Reprogramming.\nAbstract: Alzheimer's Disease (AD) is now understood as a biologically diverse condition, with amyloid and tau pathology evolving within dynamic neuroimmune networks. This challenges the traditional view that AD-related inflammation can be broadly suppressed therapeutically. We review evidence showing that neuroinflammation in AD is stage-dependent, cell-state-specific, spatially organized, and functionally complex. Microglia and astrocytes can aid in plaque containment, debris clearance, synaptic balance, metabolic adaptation, and tissue repair, but may also exacerbate injury through type-I interferon, inflammasome, complement, tumor necrosis factor, and lipid pathways. Many failed anti-inflammatory trials likely stem from mismatches in targets, timing, spatial considerations, pathway redundancy, and biomarker selection, rather than invalidating neuroinflammation as a therapeutic target. Recent single-cell and spatial transcriptomic, proteomic, metabolomic, and network-medicine studies offer a framework for precision intervention by identifying inflammatory endotypes, anatomical niches, and pathway modules. We propose the Stage-State-Space Neuroimmune Reprogramming Model (S3-NRM), aligning AD immunotherapy with disease stage, glial/endotype state, and spatial inflammatory niche, guided by fluid, imaging, and omics biomarkers. Future therapies should selectively suppress harmful immune responses while preserving beneficial glial functions.\n\nID: 42438861\nTitle: Antidepressant use and dementia, cognitive measures, and neuroimaging outcomes: A population-based cohort study.\nAbstract: Prior observational studies have reported conflicting results regarding whether antidepressant treatment reduces long-term dementia risk, likely due to confounding by indication and reverse causation. We aimed to investigate the association between baseline antidepressant use and incident dementia, incorporating cognitive and neuroimaging outcomes. We conducted a prospective cohort study using UK Biobank participants free of dementia at baseline. Antidepressant use was self-reported at baseline (2006-2010). Incident dementia was identified through linked electronic health records until December 19, 2022. Cox proportional hazards models estimated hazard ratios (HRs) for all-cause dementia, Alzheimer's disease (AD), and vascular dementia (VD), adjusting for sociodemographic, lifestyle, health-related, antidepressant indication factors, and co-medication of other anticholinergics. In subsamples, cognitive performance (n = 57,330) and structural brain imaging (n = 42,276) were examined as intermediate outcomes. Among 461,464 participants, 33,721 (7.3%) reported baseline antidepressant use. Over a mean follow-up of 13.4 years, 7,922 (1.7%) developed incident dementia. Baseline antidepressant use was associated with higher risks of all-cause dementia (adjusted HR: 1.47, 95% CI 1.36-1.60), AD (1.53, 1.36-1.73), and VD (1.44, 1.23-1.70). Users performed worse on fluid intelligence and prospective memory tasks and showed lower total and gray matter volume, regional reductions in the hippocampal gray matter and basal nucleus, and greater white matter hyperintensity volume. Baseline antidepressant use was linked to a higher risk of dementia, poorer cognitive performance, and adverse brain structural changes. These findings underscore the importance of judicious prescribing, regular cognitive monitoring, and consideration of non-pharmacological approaches in clinical care.\n\nID: 42437975\nTitle: Proteomics of post mortem brains in early- and late-onset Alzheimer's disease: Unraveling differential Aβ effects and potential AD biomarkers.\nAbstract: Alzheimer's disease (AD) occurs primarily as late‑onset (LOAD) and less frequently as early‑onset (EOAD). Its defining pathologies are hyperphosphorylated tau tangles and amyloid beta (Aβ) plaques. We analyzed the proteomes of 115 post mortem temporal lobe samples by mass spectrometry and searched with a dedicated AD spectral library including tau post‑translational modifications and Aβ isoforms to examine global protein changes in LOAD and EOAD. AD tissues showed mitochondrial and synaptic pathway downregulation and immune and small‑molecule metabolic process upregulation, with EOAD exhibiting larger fold changes. AD biomarkers were elevated, and two multi‑phosphorylated tau peptides (p‑tau231/p-tau235 and p-tau231/p-tau235/p-tau237) were detected predominantly in AD. Aβ was present in 45% of cognitively unimpaired elderly controls, with subtle proteome changes resembling an early stage of neurodegeneration. EOAD appears more aggressive. Tau p-tau231/p-tau235 and p-tau231/p-tau235/p-tau237 hold promise as novel AD biomarkers. Aβ's detection in cognitively unimpaired elderly controls precedes clinical AD symptoms.\n\nID: 42437964\nTitle: Adoption of Alzheimer's disease biomarkers by primary care clinicians: findings from the National Dementia Workforce Study.\nAbstract: Biomarkers for Alzheimer's disease (AD) are now available for clinical use; however, little is known about their use in primary care. Cross-sectional analysis of 2024 data from the National Dementia Workforce Study, a nationally representative survey of primary care providers (PCPs) who treat Medicare beneficiaries with dementia. We used survey weights to generate nationally representative estimates of self-reported biomarker use. Among 2574 PCPs, computed tomography/magnetic resonance imaging (CT/MRI) (79%) and neuropsychological testing (71%) were most commonly used, followed by positron emission tomography (PET) (18%), plasma (16%), genetic (14%), and CSF testing (9%). PCPs confident in diagnosing dementia and from specialist settings were more likely to report ordering PET, plasma, genetic, and CSF testing. This study describes patterns in the adoption of AD biomarkers in the year after Medicare expanded coverage for some biomarkers, providing a baseline for measuring changes in biomarker use. Guidelines are needed to inform PCP decision-making for biomarkers.\n\nID: 42435996\nTitle: Targeting the APOE4-driven peripheral-central immune axis: A new frontier for Alzheimer's disease therapy.\nAbstract: Alzheimer's disease (AD) is a progressive neurodegenerative disorder and a growing global health challenge. Despite decades of research dominated by the amyloid cascade hypothesis, single-target therapies aimed at Aβ or tau have largely failed, underscoring the need for a broader framework. Emerging evidence implicates neuroimmune dysfunction as a central driver of AD pathology, with the \"peripheral-central immune axis\" emerging as a critical node. The APOE4 allele, the strongest genetic risk factor for sporadic AD, plays a pivotal role in both central nervous system (CNS) lipid metabolism and peripheral immune homeostasis. This review synthesizes the association between APOE4 and peripheral immune dysregulation and its impact on neurodegeneration. We discuss APOE expression in CNS and peripheral immune cells, highlighting APOE4-associated alterations in monocyte/macrophage polarization, T cell subsets via IL-7/IL-7R downregulation, and gut microbiota composition. We delineate mechanisms by which APOE4 is associated with blood-brain barrier compromise, may promote conditions for immune cell trafficking, and contributes to neuroinflammation. Integrating preclinical and clinical evidence, we propose an \"APOE4-associated peripheral-central immune infiltration cascade\" as a unifying framework for understanding systemic AD pathogenesis. Finally, we review emerging therapeutic strategies targeting peripheral immunity and APOE, discussing multi-target approaches guided by APOE genotype and immune biomarkers, shifting from a CNS-centric toward a systemic immunomodulatory paradigm for precision medicine.\n\nID: 42434915\nTitle: Low body mass index is associated with higher rates of mild cognitive impairment and worse memory performance among older Canadian adults: An analysis of the Canadian Longitudinal Study on Aging (CLSA) database.\nAbstract: BackgroundBoth low and high body mass index (BMI) have been identified as risk factors for dementia, though the association between the range of BMI classifications and presence of mild cognitive impairment (MCI) and memory performance warrants further investigation.ObjectiveThis study aimed to investigate the association between the range of BMI classifications and presence of MCI, as well as overall memory performance, among a large Canadian sample of older adults.MethodsThis study utilized data from 40,232 participants from the Canadian Longitudinal Study on Aging (CLSA). The association between BMI and cognitive function was examined at baseline and first follow-up (3 years). Linear regression was used to model the relationship between BMI and memory performance, while logistic regression was used to assess the association between BMI and the odds of meeting criteria for MCI.ResultsIn the final regression model, a weak (partial eta-squared=0.8%, 95% CI [0.63%, 0.97%]) inverted-U relationship between BMI and REYII memory performance was demonstrated, with normal BMI showing the best performance. In the final logistic regression model, being underweight was associated with 3.22 times greater odds (95% CI [1.63, 6.39]) of meeting criteria for MCI compared to normal BMI. No association was demonstrated between change in BMI and change in cognitive performance between baseline and 3-year follow-up.ConclusionsBeing underweight is linked to higher odds of MCI, suggesting the importance of adequate nutrition in preserving cognitive health among older adults.\n\nID: 42434900\nTitle: Amyloid-related imaging abnormalities after immunotherapy: How might brain microvascular basement membrane components be involved?\nAbstract: Basement membrane components are integral to the physiologic function of cerebral microvessels. Immunotherapy (including by the use of lecanemab) in Alzheimer's disease patients may result in vascular complications identified by neuroimaging (ARIA-E and ARIA-H). This pilot study (on a relatively small number of human brain specimens) suggests one mechanism might be through the effects of lecanemab on a collagen component of said microvessel walls. It utilizes microvessels isolated from human brains (of Alzheimer's disease patients) and maintained in a viable state, to examine this mechanism using novel biochemical and molecular approaches. These yield preliminary evidence of how lecanemab may influence a specific component of the cerebral microvasculature and suggest other studies that may be used to address this important question.\n\nID: 42434591\nTitle: Mechanisms and disease associations of oxidative stress-mediated brain-bone axis dysregulation: a knowledge mapping and trend analysis based on Bibliometrics.\nAbstract: Oxidative stress, characterized by the systemic imbalance between reactive oxygen species and antioxidant defenses, is increasingly recognized as a central pathological nexus driving the dysregulation of the brain-bone axis. Despite the accumulation of empirical evidence, a systematic characterization of the field's intellectual structure and thematic progression remains absent. This study employs a multi-database bibliometric approach to map the research landscape of oxidative stress-mediated neuro-skeletal crosstalk and identify emerging research frontiers. A systematic search was performed across the Web of Science Core Collection, Scopus, and PubMed databases from their inception to April 30, 2025. Following a rigorous screening process based on predefined criteria, 717 relevant publications were included. Bibliometric mapping and network analyses were conducted using CiteSpace, VOSviewer, and the Bibliometrix R-package to evaluate collaboration patterns, co-citation structures, and keyword evolution. The analysis reveals a steady increase in research output since 2009, marked by distinct developmental phases. Early investigations primarily focused on fundamental oxidative damage mechanisms, while subsequent research transitioned toward systemic disease associations (e.g., Alzheimer's disease and osteoporosis) and targeted intervention strategies, including mesenchymal stem cell therapy and melatonin. Recent trends indicate a methodological and thematic shift toward high-resolution translational themes, such as neuroimmune regulation and the \"gut-brain-bone\" axis. Notably, \"gut microbiota\" and \"extracellular vesicles\" have emerged as high-centrality nodes, reflecting an increasing focus on inter-organ communication and systemic redox modulation. This study provides the first comprehensive mapping of the research trajectories within the oxidative stress-mediated brain-bone axis field. The findings delineate a clear progression from isolated mechanistic studies toward integrated, multi-system frameworks, underscoring the shift toward precision medicine and translational applications. By identifying current research gaps and emerging hotspots, this analysis offers a systematic reference for future interdisciplinary investigations and the development of targeted therapeutic strategies for neuro-skeletal comorbidities.\n\nID: 42434375\nTitle: A real-world feasibility study: at home longitudinal use of the Cumulus NeuLogiq® platform for electrophysiological and neurocognitive measures in patients with mild Alzheimer's Disease dementia.\nAbstract: Dementias, including those caused by Alzheimer's Disease (AD), are a leading global cause of death, necessitating improvements in early detection and development of more effective disease-modifying therapies. Well-validated pen-and-paper measures serve as the primary method used for cognitive assessment in research and clinical trials in AD. However, these suffer from rater error, infrequent \"snapshot\" bias, and have limited sensitivity to early-stage pathology, which presents challenges for measuring efficacy in prevention trials. Recent technological advances offer the potential to measure subtle cognitive changes and account for day-to-day variability through real-world data collection. The Cumulus Neuroscience NeuLogiq® platform (\"the platform\"), is comprised of a wireless electroencephalography (EEG) headset, tablet-based cognitive tasks based on well-established paradigms which were designed to be user-friendly based on patient panel inputs, third party integrations (mood, speech and sleep assessments) and cloud-based analytics. This platform has demonstrated utility in healthy populations and may enable objective, frequent, and patient-centered disease tracking in AD and other CNS disorders. This paper presents findings from a 52-week study involving individuals with mild AD dementia and healthy controls. Analyses focus on usability (e.g., ease of use ratings and reported technical issues) and feasibility (e.g., adherence; withdrawal rates) of using the platform, unsupervised, in the real-world at home setting and exploring how baseline cognitive status and demographic factors impact platform usability. Longitudinal study data after 12 months offer valuable insights into the feasibility of the platform for patients with mild AD enrolled in long-term studies, such as clinical trials. The participants' high adherence to the protocol underscores the practicality of utilizing the platform in this context. Although participants with dementia reported lower confidence levels (31.6%, N = 18) and encountered some minor technical challenges during the initial home setup (accounting for 16.1% of issues reported in Stage 1), they nonetheless demonstrated strong engagement, achieving an overall adherence rate of 77% across the 52-week study protocol. This demonstrates that even participants with dementia remain able and willing to use the EEG headset and complete tablet-based cognitive tasks over a year, from the comfort of their homes.\n\nID: 42432729\nTitle: Reshaping the immune landscape: next-generation microglia-targeted therapies for Alzheimer's disease.\nAbstract: Alzheimer's disease (AD) is a significant global health challenge characterized as a multifactorial neurodegenerative disorder, involving amyloid-β (Aβ) and Tau aggregation, neuroinflammation and progressive neuronal injury. While Amyloid-targeted therapies have achieved a breakthrough in prevention of Aβ aggregation, the strategies face notable limitations in achieving curative outcomes and management of amyloid-independent central nervous system (CNS) dysfunction. Consequently, targeting microglia, the central immune cells of the brain, has emerged as a promising strategy to enhance the specificity and efficacy of AD interventions. Accumulating evidence indicates microglial dysfunction is not a passive immune bystander of AD, but serves as a critical mechanistic nexus linking Aβ accumulation and AD symptomatic phenotype. This review critically examines the \"next generation\" of microglial therapeutics, moving beyond broad immunosuppression to precision phenotype modulation. We highlight breakthrough strategies in recent years including immune reconstitution, metabolic reprogramming, nanomaterial-mediated drug delivery, and the revolutionary potential of iPSC-derived microglia replacement. By elucidating the rationale underlying the specific strategies based on microglial biofunction and potential molecular mechanism in AD pathology, we provide an overview of current development of clinical trials and cutting-edge modalities aimed at restoring microglial homeostasis, affording an opportunity to alter the AD trajectory. This review aims to delineate the path from bench to bedside and propose promising pathways to overcome current bottlenecks in AD drug development.\n\nID: 42432263\nTitle: Repurposing apremilast for alzheimer's disease: multitarget modulation of cAMP‑PI3K/Akt-GSK‑3β and NF‑κB signaling.\nAbstract: Alzheimer's disease (AD), the leading cause of dementia worldwide, represents a growing global health challenge driven by population aging, the absence of effective disease-modifying therapies, and its inherently multifactorial pathogenesis. This pathogenesis is characterized by amyloid-β (Aβ) aggregation, tau hyperphosphorylation, persistent neuroinflammation, oxidative stress, and synaptic dysfunction. Conventional single-target interventions have consistently failed against this complex interplay of molecular events, thereby highlighting the need for multitarget, systems pharmacology approaches capable of simultaneously modulating convergent pathways. Apremilast (APR), an FDA-approved, orally bioavailable phosphodiesterase-4 (PDE4) inhibitor, has recently emerged as a favorable drug repurposing candidate capable of elevating intracellular cAMP and triggering a cascade of neuroprotective mechanisms. Preclinical investigations from Aβ-challenged neuronal cultures to high-fat diet/streptozotocin-induced rodent models of AD demonstrate that APR attenuates Aβ-induced cytotoxicity, improves cognitive performance, and preserves neuronal and synaptic integrity. Mechanistically, APR mitigates NF-κB-mediated neuroinflammation through IκBα stabilization, thereby reducing the release of proinflammatory cytokines such as TNF-α and IL-6; activates the Nrf2/HO-1 antioxidant defense pathway, and, via cAMP-dependent PI3K/Akt signaling, inhibits GSK-3β to prevent tau hyperphosphorylation, synaptic loss, and neuronal degeneration. This review synthesizes current mechanistic evidence supporting apremilast as a potential multitarget repurposing candidate in AD, thereby addressing key knowledge gaps in the current literature. All supporting evidence was compiled from peer-reviewed sources indexed in PubMed, Web of Science, and Scopus. Guided by network pharmacology and systems biology frameworks, APR's polypharmacological profile positions it as a compelling multitarget candidate for advanced in vivo validation, human iPSC-derived neuronal studies, and AI-driven therapeutic discovery pipelines.\n\nID: 42430964\nTitle: Suboptimal adherence to brain health recommendations in patients pursuing anti-amyloid antibody therapy for Alzheimer's disease: Report from the Brain Health Vital Signs project.\nAbstract: Consensus is consolidating around a set of lifestyle and medical factors that can promote brain health and reduce the risk of dementia for older adults and further decline for those with early Alzheimer's disease (AD) and related disorders. Little is known about the degree to which recommended brain-healthy behaviors have been adopted by patients with early AD pursuing anti-amyloid antibody therapy (AAT), a proactive group interested in doing what is under their control to help preserve cognitive and functional status. Here, initial results of a clinically relevant quality improvement study are reported. To determine the extent to which patients pursuing AAT for AD adhere to consensus-based brain health recommendations. One hundred fifty patients with mild cognitive impairment (MCI) or mild dementia due to AD seeking AAT were studied and compared to a group of 117 patients with MCI or mild dementia who were not pursuing AAT. Using a clinical survey tool developed for the project, patients were assessed on 15 modifiable risk factors for cognitive decline and dementia, including 11 via e-survey (diet, physical activity, cognitive activity, sleep, social engagement, smoking status, alcohol consumption, hearing, vision, mood/stress, and purpose in life) and 4 via electronic medical record (EMR) (blood pressure, BMI, LDL cholesterol level, and HbA1c). For each factor, the percentage of each of the two patient groups that was not optimally adhering to brain health-related guidelines was calculated. For each individual, the total number of factors not optimally being followed was determined. Less than 3% of patients with early AD pursuing AAT were following or had anthropometric measures/lab values in line with all 15 brain health recommendations. The five factors with the lowest adherence rates involved physical activity, mood/stress, HbA1c, blood pressure, and BMI, with 44-63% of the AAT group suboptimally following consensus-based guidelines. For 11 of 15 factors, >25% of the group were not adhering to guidelines. No robust differences in degree or pattern of adherence to guidelines were observed between patients pursuing and not pursuing AAT. There were no data in the EMR for HbA1c in >42% of patients and for LDL in >23% of patients in either group. Suboptimal adherence to brain health recommendations may be common among patients with early AD, whether they are pursuing AAT or not. These results suggest that healthcare systems may need to develop more effective strategies and individualized interventions for addressing modifiable risk factors for cognitive decline and dementia, and more efficacious procedures for ensuring that relevant, actionable data associated with brain health are updated in the EMR.\n\nID: 42430835\nTitle: Glymphatic dysfunction in neurodegeneration: From impaired clearance to mechanism-driven therapeutic innovation.\nAbstract: Glymphatic system refers to a system that involves perivascular clearance mechanisms within the brain, which are crucial for the elimination of neurotoxic proteins such as amyloid-β (Aβ) and tau proteins in Alzheimer's disease (AD), α-synuclein in Parkinson's disease (PD), and mutant huntingtin (mHTT) in Huntington's disease (HD). There is mounting evidence suggesting that glymphatic dysfunction is an important cause of neurodegenerative diseases, characterized by failure of cerebrospinal fluid-interstitial fluid (CSF-ISF) exchange due to abnormal clearance. Mechanistically, this dysfunction is affected by aging, astroglial aquaporin-4 (AQP4) depolarization, vascular impairment, sleep abnormalities, oxidative damage, and neuroinflammation. Additionally, aberrant glymphatic flow acts as a crucial link between peripheral and central pathologies, amplifying neurodegeneration via altered solute transport and inflammation signaling. Glymphatic dysfunction has been found to be involved in diseases such as AD, PD and HD, thus indicating the widespread significance of glymphatic pathology. Therapeutically, targeting glymphatic function through modulation of AQP4 polarization, improving sleep-dependent clearance, and decreasing oxidative and inflammatory mechanisms may provide promising strategy for disease modification. This review provides a comparative and mechanistic overview of glymphatic dysfunction across AD, PD, and HD, highlighting peripheral-central interactions, biomarkers, imaging approaches, and therapeutic strategies, while addressing unresolved issues related to transport mechanisms, causality versus epiphenomenon, and translational limitations.\n\nID: 42427748\nTitle: Early Loss of Deep Restorative Sleep and Auditory Stimulus Evoked 40-Hz activity of Hippocampal Parvalbumin Neurons in the APP/PS1 Mouse Model of Alzheimer's Disease.\nAbstract: Sleep abnormalities and dysfunction of gamma band (30-80 Hz) activity generated by parvalbumin (PV) interneurons are early characteristics of Alzheimer's disease (AD) which correlate with the severity of amyloid-β deposition (Aβ) and cognitive impairment. However, the timing of these alterations in vivo with respect to disease progression is unclear. Here, in longitudinal recordings from APP/PS1/PV-cre (AD mice) from 3-6 months, we found reduced sleep slow-wave power (0.5-4 Hz) in hippocampus and medial prefrontal cortex in AD mice as young as 3 months old, compared to non-AD (PV-cre) mice, well before overt pathology. This finding was primarily due to reductions in the NREM delta range (1.5-4 Hz), a hallmark of restorative functions of sleep. In contrast, beta (15-30 Hz) power linked to insomnia was significantly higher across all sleep-wake states. Loss of deep NREM sleep was not compensated by an increase in NREM sleep time, instead NREM sleep during the dark (active) phase was slightly but significantly lower in AD mice. 40-Hz auditory steady-state responses and associated evoked calcium responses of hippocampal PV neurons recorded using fiber photometry were also impaired by 3 months old. However, Y-maze performance in 3- and 6-month-old AD mice was not significantly different from non-AD mice. These results reveal reduced deep sleep and PV-associated 40-Hz activity as very early changes amenable to early intervention occurring prior to cognitive deficits. Furthermore, they establish APP/PS1 mice as a good model to causally test the relationship between sleep, PV neuronal activity and amyloid-mediated pathology.\n\nID: 42443606\nTitle: Tau physiology and pathology: impacts on cellular structures and neurodegenerative diseases.\nAbstract: This review explores the crucial roles of the tau protein in neuronal integrity and its dysregulation in neurodegenerative diseases (NDs), particularly tauopathies. Key features include abnormal tau phosphorylation, leading to insoluble aggregates and neuronal dysfunction. Various therapeutic strategies, such as reducing tau phosphorylation, inhibiting aggregation, and enhancing clearance through autophagy and immunotherapies, are discussed. Promising candidates such as anle138b and methylene blue display efficacy in preclinical models. The interplay between tau and Aβ pathology is also highlighted, emphasizing the complexity of therapeutic approaches. A thorough understanding of tau functions is essential for developing targeted treatments to combat tau-related neurotoxicity and advance therapies for Alzheimer's disease (AD). This article examines the dual role of tau in physiology and pathology, highlighting its effects at both the cellular and subcellular levels. These findings underscore the critical importance of the tau protein in preventing NDs and suggest that a deeper understanding of its functions could improve treatment strategies for tau-related disorders.\n\nID: 42442912\nTitle: Metallospecies and their biological functions in Alzheimer's disease.\nAbstract: This chapter critically explores the role of metallospecies homeostasis in the pathophysiology of Alzheimer's disease (AD), going beyond the traditional amyloid protein-centered approach. The discussion integrates biochemical, molecular, and analytical perspectives to elucidate how metal-biomolecule interactions influence protein misfolding, protein aggregation, and neurotoxicity. Furthermore, the chapter reviews cutting-edge metallomic approaches, including advanced speciation analyses and metal bioimaging techniques, to demonstrate how these tools allow for the precise characterization of the chemical identity, coordination environment, and spatial distribution of metal species in brain tissue. By discussing mechanistic insights with analytical advances, this chapter provides a comprehensive framework for understanding the contribution of metal dysregulation to AD and identifies new directions for diagnosis and therapeutic intervention.\n\nID: 42442908\nTitle: Role of ESCRT pathway and autophagy in neurodegenerative diseases.\nAbstract: Neurodegenerative diseases are characterized by progressive neuronal dysfunction and loss resulting from impaired proteostasis and vesicular trafficking. Neurons are particularly vulnerable to these processes due to their post-mitotic nature and complex architecture. Autophagy and the endolysosomal system constitute the primary degradative pathways responsible for maintaining neuronal homeostasis. However, increasing evidence indicates that their effective function critically depends on coordination with the endosomal sorting complexes required for transport (ESCRT). Beyond their canonical role in multivesicular body biogenesis and membrane scission, ESCRT components are now recognized as essential regulators of autophagosome closure, amphisome formation, autophagosome-lysosome fusion, and endolysosomal membrane repair. Disruption of this ESCRT-autophagy interface has emerged as a common pathological feature across major neurodegenerative disorders, including Alzheimer's disease, Parkinson's disease, and amyotrophic lateral sclerosis/frontotemporal dementia. This review synthesizes evidence from genetic, biochemical, and neuropathological studies to highlight shared molecular nodes, such as ESCRT-III components, the VPS4 ATPase, the adaptor protein ALIX, and late endosomal regulators, including Rab7, that couple membrane remodeling to autophagic flux. Failure of these regulatory checkpoints destabilizes endolysosomal integrity, arrests autophagic maturation, and promotes the accumulation of toxic protein species, thereby driving progressive neuronal degeneration. By framing neurodegeneration through the lens of ESCRT-autophagy coupling failure, this review provides a unified mechanistic perspective that links diverse pathogenic proteins to shared cellular vulnerabilities and identifies ESCRT-mediated membrane dynamics as a critical determinant of neuronal survival.\n\nID: 42442802\nTitle: The Role of Genetic Alterations in the Emergence of Alzheimer's Disease in Down Syndrome: A Review.\nAbstract: Down syndrome (DS), the most common chromosomal disorder, is associated with an accelerated aging process, increasing the risk of early-onset Alzheimer's disease. This review examines genetic factors involved in the development of Alzheimer's disease (AD) in people with DS. A systematic search in major databases was conducted, and articles from 2020 to 2025 that met the predefined inclusion criteria were included. The results showed that the prevalence of AD was above 60% in people with DS older than 65 years, the mean age at diagnosis was 53 years, and the mortality occurred around 59 years. The main genetic factor identified was the overexpression of the APP gene, along with other genes such as DYRK1A, RCAN1, SOD1, APOEε4, and genes involved in the immune response, as well as posttranscriptional dysregulation. Diagnosis remains a challenge due to the pre-existent intellectual disability and the atypical clinical presentation of the disease; however, the development of adapted neuropsychological tests, biomarkers, and neuroimaging techniques is expected to facilitate early diagnosis. The connection between both diseases is the result of multiple genetic factors that lead to early onset and accelerated progression of AD. It is essential to achieve timely diagnosis and provide early treatment to improve quality of life of both patients and their caregivers.\n\nID: 42441515\nTitle: Evaluating Triptolide Effects on Hippocampal Gephyrin, Collybistin, and Autophagy in an Aβ1-42 Mouse Model.\nAbstract: Alzheimer's disease is associated with synaptic dysfunction, but standardized procedures for evaluating how Aβ-induced pathology affects inhibitory synapse-associated proteins and autophagy-related signaling after candidate intervention remain limited. This protocol describes a workflow for establishing an Aβ1-42-induced Alzheimer's disease-like mouse model and assessing the effects of triptolide on hippocampal Gephyrin, Collybistin, PI3K/Akt/GSK-3β signaling, and autophagy-related markers. Adult C57BL/6J mice receive bilateral intracerebroventricular injection of Aβ1-42 prepared under aggregation-inducing conditions, followed by daily intraperitoneal administration of triptolide with or without the PI3K inhibitor LY294002. Spatial learning and memory are evaluated using Morris water maze testing. Hippocampal neuronal injury and Aβ deposition are assessed by hematoxylin and eosin staining and Aβ immunohistochemistry, and hippocampal lysates are analyzed by Western blotting to quantify Gephyrin, phosphorylated Gephyrin, Collybistin, PI3K/Akt/GSK-3β signaling proteins, LC3-II/I, and p62. Key procedural considerations include standardized Aβ1-42 preparation, accurate stereotaxic injection, consistent behavioral testing conditions, blinded region-of-interest selection, and standardized image and densitometry analysis. Using this workflow, Aβ1-42 administration produced spatial learning and memory deficits, hippocampal neuronal injury, Aβ deposition, reduced Gephyrin and Collybistin expression, altered PI3K/Akt/GSK-3β signaling, and increased LC3-II/I and p62 accumulation. Triptolide partially reversed these behavioral, histological, and molecular changes, whereas LY294002 attenuated its effects. This protocol can be used to evaluate Aβ-induced hippocampal molecular alterations and candidate interventions, while recognizing that this model does not reproduce the chronic, multifactorial progression of human Alzheimer's disease.\n\nID: 42440728\nTitle: Reprogramming lipid metabolism for cognitive restoration in Alzheimer's via PLA2G4E.\nAbstract: Growing evidence implicates dysregulated brain lipid metabolism in Alzheimer's disease (AD) pathogenesis, influencing membrane integrity, neuroinflammation, and amyloid beta and tau pathology, thereby representing a promising therapeutic target. However, therapeutic strategies targeting lipid pathways remain largely unexplored. The therapeutic potential of PLA2G4E, previously identified in our earlier work, was validated in the APPNL-G-F AD mouse model using a translational gene-delivery approach with a blood-brain barrier-penetrant adeno-associated vector (AAV) (AAVP31) to achieve widespread brain expression. Brain lipidomics was performed to investigate the molecular mechanisms underlying treatment effects. PLA2G4E expression rescued memory deficits, reduced tau phosphorylation, and improved brain glucose metabolism and cognitive performance in AD models and aged wild-type mice. These effects were accompanied by partial normalization of disease-associated lipid metabolic alterations. These findings support PLA2G4E as a promising therapeutic target in AD and provide mechanistic evidence linking modulation of lipid metabolic pathways to synaptic and cognitive rescue.\n\nID: 42440589\nTitle: P2-engineered exosomes encapsulating curcumin alleviate cognitive decline in AD-like mice by improving microglia-related neuropathology.\nAbstract: Natural exosomes, as drug carriers, can deliver anti-inflammatory agents across the blood-brain barrier (BBB) to lesion sites in the brain, thereby demonstrating immense potential in the treatment of brain inflammation-related diseases. However, the application of natural exosomes is constrained by their poor targeting ability. Herein, we report a novel drug delivery system (P2-Exo-Cur) constructed by engineering exosomes to display the P2 peptide on their surface, thereby enabling targeted delivery of curcumin to microglia. Our results revealed that P2-Exo-Cur possesses a nanoscale membrane structure and can efficiently deliver curcumin to microglia both in vitro and in vivo. This technology provides a microglia-targeted delivery approach for anti-inflammatory agents such as curcumin, while overcoming the undesirable off-target effects that limit their efficacy. Furthermore, treatment of lipopolysaccharide (LPS)-induced inflammatory BV2 cell models with P2-Exo-Cur significantly suppressed the polarization of BV2 cells toward the M1 phenotype, as well as the secretion of pro-inflammatory cytokines. Finally, we also validated the excellent therapeutic potential of this technology in the 5xFAD mouse model. In conclusion, in this study, we for the first time constructed engineered exosomes that can specifically bind to the NCAM protein on microglia to achieve precise delivery of curcumin by expressing the P2 peptide on their surface, exerting beneficial effects in AD treatment without causing significant adverse effects. This strategy may offer a non-invasive and innovative therapeutic method for the management of brain inflammation-related diseases.\n\nID: 42440182\nTitle: Silymarin attenuates senescence-exacerbated amyloidogenesis, neuroinflammation, and oxidative stress in lipopolysaccharide-induced memory impairment in aging mice.\nAbstract: Accelerated cellular perturbations such as cellular senescence, neuroinflammation and oxidative stress are hallmarks of Alzheimer's disease, a neurodegenerative disease associated with memory decline. However, the senolytic effects of silymarin, a flavonolignan with known antioxidant and anti-inflammatory properties, on memory decline remain unknown. Hence, we investigated the effect of silymarin on doxycycline-mediated senescence and exacerbated neuroinflammation in lipopolysaccharide-induced memory-impaired mice. Five groups of adult Swiss female mice (n = 10) were exposed to doxycycline-induced accelerated senescence for 21 days, followed by lipopolysaccharide-induced neuroinflammation from days 15-21, and silymarin (50 and 100 mg/kg, p.o.) or donepezil (1 mg/kg, p.o.) treatments. Spatial and non-spatial memory, and social and motor function tests in mice were assessed. Biochemical assays were performed on the prefrontal cortex and hippocampus to assess senescence-associated secretory phenotypes (SASPs), including SA-β-galactosidase activity, cytokines (TNF-α, IL-6, IL-10), amyloid-beta levels, acetylcholinesterase activity, oxidative stress markers, and molybdoenzymes. Doxycycline-lipopolysaccharide-exacerbated memory impairments were reversed by silymarin, accompanied by reduced molybdoenzymes, malondialdehyde, nitrite, and elevated antioxidants (glutathione, superoxide-dismutase, catalase) in the prefrontal cortex and hippocampus. Additionally, silymarin reverses doxycycline-exacerbated lipopolysaccharide-induced increases in IL-6 and TNF-α release and myeloperoxidase activity while also reducing IL-10 levels. Similar to donepezil, silymarin reduced heightened acetylcholinesterase activity associated with doxycycline-enhanced lipopolysaccharide-induced accumulation of cortical SA-β-galactosidase and amyloid-β levels, relative to the doxycycline-lipopolysaccharide group. These findings suggest that silymarin ameliorates doxycycline-lipopolysaccharide-exacerbated memory impairment and modulates senescence and neuroinflammation by reducing oxidative stress, SASP marker levels, and amyloid-beta concentrations in the prefrontal cortex and hippocampus of mouse brains.\n\nID: 42439654\nTitle: Emerging New Pathways in Malignant Neoplasms and Neurodegenerative Disorders: Perspectives for Therapeutics.\nAbstract: Neurodegenerative disorders such as Alzheimer's disease (AD) and malignant neoplasms are among the most prevalent age-associated diseases worldwide. Although cancer is characterized by uncontrolled proliferation, resistance to apoptosis, and metabolic reprogramming, AD and other neurodegenerative disorders such as Lewy body disease (LBD) including Parkinson's Disease (PD) and fronto-temporal lobar degeneration (FTLD) are defined by synaptic dysfunction, neuronal loss, neuroinflammation, and impaired proteostasis with misfolded protein aggregates. Despite these contrasting phenotypes, converging epidemiological and molecular data support an inverse relationship between cancer and neurodegenerative disorders, whereby a history of cancer is associated with reduced AD risk, whereas AD is linked to a lower incidence of multiple malignancies. These observations suggest that oncogenesis and neurodegeneration may represent divergent outcomes of shared biological processes dysregulated during aging. This conundrum likely reflects differential regulation of core cellular pathways governing cell survival, stress responses, metabolism, and genomic integrity but could also reflect the differential influence of aging pathways and secreted growth factors. Pro-survival and proliferative signaling pathways commonly activated in cancer, including PI3K-AKT-mTOR signaling, altered p53 function, enhanced DNA damage tolerance, and anabolic metabolism, are often impaired in AD, LBD and FTLD, where neurons exhibit heightened vulnerability to stress, mitochondrial dysfunction, defective autophagy, and activation of pro-apoptotic cascades. Conversely, tumor-suppressive mechanisms that restrain proliferation may protect against malignancy but increase susceptibility to degeneration in post-mitotic neurons. Aging-related processes such as cellular senescence, immune dysregulation, and loss of proteostasis may further exert divergent effects in oncogenesis and neurodegeneration. This review aims to clarify associations between specific cancer types and neurodegenerative disorders, examine shared and opposing selected molecular mechanisms linking specific cancers and neurodegeneration, and contextualize these relationships within broader aging pathways (e.g., cell senescence, proteostasis). By integrating epidemiological, mechanistic, and therapeutic perspectives, we highlight unifying biological principles and translational opportunities at the intersection of cancer, neurodegeneration, and aging.\n\nID: 42439636\nTitle: Human Microglial Molecular Alterations in Aging and Alzheimer's Disease.\nAbstract: Microglia, the resident innate immune cells of the central nervous system, are central players in brain development, healthy aging, and degenerative pathology, including Alzheimer's disease (AD). Aging is a major risk factor for AD, and various studies have identified alterations in microglial molecular signatures and morphological patterns that overlap with microglial states during aging. However, the mechanisms underlying the divergence of aging trajectories toward disease remain unclear. Thus, understanding the molecular changes in microglia during aging and AD pathology is crucial to elucidating the mechanisms that drive disease progression. In this review, we examine current advances in understanding the phenotypic alterations in human microglia, highlighting gene signatures and morphological changes that may aid in defining microglia's molecular and functional programs in healthy aging and over the course of AD. We further explore the roles of oxidative stress and cellular senescence in driving the development of a chronic reactive state in microglia during aging, which may also contribute to the complex process underlying the onset and progression of AD pathology. This review highlights the advancements in therapeutic strategies focused on targeting pertinent pathological microglial changes during aging and in disease to mitigate the AD neurodegenerative process.\n\nID: 42439628\nTitle: Lymphoid-like Suppressive Microglia in Alzheimer's Disease: A New Neuroimmune Regulatory Axis?\nAbstract: Microglia are central regulators of Alzheimer's disease pathogenesis, but their roles cannot be reduced to a simple protective-versus-harmful dichotomy. Genetic, single-cell, and spatial studies have shown that Alzheimer 's-associated microglia occupy diverse disease-linked states shaped by amyloid plaques, tau pathology, lipid stress, complement activation, astrocyte signaling, aging, and immune genetic risk. Among the regulatory nodes controlling these states, SPI1, which encodes the myeloid transcription factor PU.1, has emerged as a key determinant of microglial identity and disease responsiveness. Human genetic studies suggest that reduced SPI1 expression may be protective, whereas experimental data indicate that excessive PU.1 suppression can impair essential microglial functions. This review examines the emerging concept that partial, plaque-associated reduction in PU.1 may enable a distinct lymphoid-like immunoregulatory microglial program marked by CD28 expression. Recent evidence suggests that PU.1-low CD28-positive microglia may restrain neuroinflammation and amyloid pathology, raising the possibility that Alzheimer's plaques induce not only inflammatory and phagocytic microglial responses, but also endogenous suppressive programs that limit tissue damage. We discuss this proposed PU.1/CD28 regulatory axis in relation to disease-associated microglia, TREM2-APOE signaling, complement-mediated synapse loss, antigen-presentation pathways, plaque-niche biology, and therapeutic microglial reprogramming. We also highlight major unresolved questions, including whether PU.1-low CD28-positive microglia are present and functional in human Alzheimer's disease, whether they are specific to amyloid-rich niches or extend to tau and mixed pathologies, and how such states could be safely manipulated without disrupting essential immune surveillance. We propose that lymphoid-like suppressive microglia represent a promising but still unproven framework for understanding protective neuroimmune regulation in Alzheimer's disease and for developing state-specific microglial therapies.\n\nID: 42439047\nTitle: The social environment and cognitive aging over the life course: laying out critical concepts and research gaps.\nAbstract: The social environment refers to our interpersonal relations, workplaces, and neighborhoods, towns, or cities in which we live. A growing literature indicates that social environments are related to cognitive aging and risk of Alzheimer's disease and related dementias (AD/ADRD). Still, relatively little is known about how social-environmental exposures affect cognitive function over the life course and into older ages. Addressing this limitation, our paper outlines key features of the social environment and recommends priority areas of research on the social environment and cognitive aging. We divide our discussion into three subdomains: social connections, residential context, and work context. We then identify important gaps in the conceptual and empirical literature before outlining avenues for future research to strengthen our understanding of how social-environmental exposures over the life course link with cognitive function and AD/ADRD risk in late life.\n\nID: 42437010\nTitle: Relation between voxel-based specific regional analysis system for Alzheimer's disease (VSRAD) on 3-tesla MRI and cognitive performances: Practical application in clinical settings.\nAbstract: Voxel-based specific regional analysis system for Alzheimer's disease (VSRAD) software using MRI scanner allows quantification of hippocampal and parahippocampal atrophy in the medial temporal structures by Z-score, and this score is widely used in clinical Alzheimer's disease (AD) diagnosis. However, it is unclear whether the Z-score is useful to discriminate normal aging from cognitive impairment (CI) or mild cognitive impairment (MCI). The present study examined the associations between VSRAD Z-score and cognitive performance quantified by Memory Performance Index (MPI) and determined a Z-score cut-off value. Three-tesla brain MRI was conducted in 100 outpatients without dementia, and all MRI data were analyzed using VSRAD. The target region of interest (ROI) mainly consisted of the para hippocampal gyrus. The degree of atrophy in the ROI was obtained from the averaged positive Z-score of the ROI. Cognitive performance was evaluated with the Japanese version of the MCI screen (MCIS). Patients were classified into normal (NL) and below normal (BNL) cognitive groups by MPI. The relation between MPI and VSRAD Z-score were assessed with logistic regression analysis, and the cut-off value for Z-score was determined by receiver operating characteristic curve analysis. Sixty-two percent (62%) were identified as the BNL group by MPI. Univariate analyses found that the BNL group had a significantly higher age, shorter years of education, and higher Z-score in VSRAD compared to the NL group, but no statistically significant difference was observed between genders. Bivariate correlation found that MPI, which is adjusted for age, gender, and years of education, was significantly correlated with Z-score assessed by VSRAD (Pearson's r = -0.52, p < .001). A subsequent logistic regression of VSRAD Z-score on BNL classification was used to generate a receiver operating characteristic curve (AUC = 0.75). The Youden index was applied to identify a cut-off value of VSRAD Z-score of 1.14 (sensitivity = 62.9%; specificity = 84.2%) to classify MPI < 50.2 (BNL) with overall accuracy of 73.5%. VSRAD Z-score using VSRAD software was one independent factor significantly associated with cognitive performance measured by MPI. The determination of a cut-off value for Z-score (1.14) that can help discriminate normal patients from those with MCI.\n\nID: 42435857\nTitle: Cellular Basis of Medium Flow-Mediated Reduction of Aβ Neurotoxicity in Cultured Neurons.\nAbstract: Alzheimer's disease (AD) is a neurodegenerative disorder characterized by elevated concentrations of amyloid β1-42 (Aβ1-42) in the brain, where it exerts neurotoxic effects. A recent study demonstrated that medium flow at approximately 10 μm/s reduces Aβ1-42 neurotoxicity in explant brain cultures containing neurons and beating ependymal cilia; however, the underlying mechanisms remain unclear. Neurons migrating from the explant and located within 300 μm of the beating cilia were exposed to cilia-generated medium flow, allowing analysis of Aβ1-42 toxicity under fluid flow conditions. Aβ1-42-containing putative EV-related extracellular particles (putative EV-related Eps), with diameters of 100-400nm were detected in the culture medium and exhibited neurotoxic effects. Pharmacological inhibition of EV release and endocytosis reduced intracellular accumulation of Aβ1-42 and attenuated neuronal toxicity. Under medium flow, fewer putative EV-related EPs bound to neurons, and their binding duration was significantly shortened. Rhodamine-conjugated concanavalin A staining revealed enhanced cell-surface glycan labeling in damaged neurons on the non-ciliated side compared with neurons on the ciliated side. These results suggest that shear stress reduces neuronal accumulation of Aβ1-42-containing putative EV-related EPs, likely through modulation of cell-surface glycosylation composition.\n\nID: 42435764\nTitle: Neuron-Targeted Exosomal Delivery of siRNA Against RIPK3 Slows Neurodegenerative Progression in Alzheimer's Disease.\nAbstract: A major challenge in RNA therapeutics for central nervous system disorders is the lack of delivery systems capable of crossing the blood-brain barrier (BBB) while achieving cell-type-specific targeting. Herein, we develop an engineered exosomal siRNA delivery platform for systemic, neuron-targeted RNA transport to the brain. The platform leverages exosomes derived from an immortalized mouse hippocampal neuronal cell line as a biomimetic and functionally privileged material source, enhancing neuronal uptake and intracellular delivery efficiency. Through surface functionalization with a rabies virus glycoprotein-derived peptide, the system enables receptor-mediated BBB transcytosis and programmable siRNA loading. In human cortical organoids, the platform achieves efficient cytosolic delivery and robust gene silencing in neurons, demonstrating high delivery precision and bioavailability. As a proof of concept, targeting receptor-interacting protein kinase 3 (RIPK3) modulates necroptosis, a key pathway in inflammatory neurodegeneration. In transgenic mouse models, systemic administration suppresses RIPK3/MLKL signaling, reduces neuronal loss, and alleviates neuroinflammation and tau-associated pathology. Transcriptomic analyses further indicate stabilization of neuronal homeostasis across vulnerable brain regions. Collectively, the study establishes a modular and programmable exosomal RNA delivery platform and highlights age-defined, cell-derived biomaterials as a generalizable strategy for overcoming delivery barriers in neurological diseases.\n\nID: 42435703\nTitle: Rationally designed phytochemical-derived carbamate hybrids unveiling potent inhibition of cholinesterase and amyloid-β peptides.\nAbstract: Alzheimer's disease (AD) is most likely to be caused by the accumulation of Aβ and dysfunction of the cholinergic pathology. Oxidative damage, alterations of brain glucose metabolism, and cognitive impairment are all demonstrated in the STZ models. In order to overcome such effects, a new set of phenolic-carbamate conjugates (5a-5h) was synthesized, and their structures were elucidated using FTIR, UV, and NMR spectroscopy. The in silico studies confirmed excellent binding capabilities against AChE and Aβ targets. In vitro antioxidant assays depicted a significant free radical scavenging ability, with compound 5c exhibiting the enhanced effect. Cell line study with SH-SY5Y and PC12 cells showed greater % cell viability. AChE activity demonstrated compound 5c has significant effectiveness (IC50 = 1.98 uM). Neurobehavioral activity showed an improvement in learning and memory during behavioural assessments. In vivo antioxidant study showed greater scavenging activity (SOD, CAT, GSH), reduced of oxidative stress (MDA, NO), and the improvement in total antioxidant activity. Overall, the compound 5c has demonstrated significant results comprising decreased cholinesterase and Aβ inhibition deciphering enhanced cholinergic restoration. Hippocampal integrity was preserved, as it was confirmed by histopathological examination. It concludes that bromo-vanillyl carbamate derivative 5c (30 mg/kg) has potent antioxidant, anti-amyloid, and neuroprotective characteristics, rendering it a promising multitarget lead that warrants further investigation for the treatment of AD.\n\nID: 42435043\nTitle: Exploring thiazole conjugates as cholinesterase inhibitors for Alzheimer's disease treatment.\nAbstract: Alzheimer's Disease (AD), a major global health concern, is marked by memory loss and cognitive decline, especially in the elderly. Cholinergic hypothesis is one of the leading hypotheses toward the treatment of AD, prompting the development of cholinesterase (ChE) inhibitors. Acetylcholinesterase (AChE) remains a vital therapeutic target due to its role in enhancing acetylcholine levels and neural function. The natural products, synthetic analogs, and hybrid molecules have been evaluated as inhibitors of ChEs. Recent studies highlight thiazole-fused heterocyclic scaffolds and their derivatives as promising ChE inhibitors with neuroprotective potential. This article covers the synthesis of conjugates of thiazole with piperazine, benzimidazole, pyrazole, and other heterocyclic compounds, along with their potential as ChE inhibitors. This article will be useful to medicinal chemists and pharmaceutical industries to design and synthesize library of thiazole conjugates.\n\nID: 42434808\nTitle: Brain targeting and trafficking of extracellular vesicles in central nervous system diseases: a therapeutic roadmap.\nAbstract: Extracellular vesicles (EVs) mediate intercellular signaling in the central nervous system (CNS) by transferring lipids, proteins, and nucleic acids among neurons, glia, endothelium, and immune cells. Brain targeting depends on a linked sequence: EV ligands and adsorbed protein coronas engage receptor modules, select endocytic routes, determine intracellular fate, and define the therapeutic readouts. These fates include lysosomal degradation, recycling, rare cytosolic delivery, or transport across the blood-brain barrier (BBB). In disease, the same pathways can disseminate proteopathic seeds and amplify neuroinflammation. Heparan sulfate proteoglycans (HSPGs) and LDL receptor family members, including low-density lipoprotein receptor-related protein 1 (LRP1), regulate tau, α-synuclein, and amyloid-β handling. Phosphatidylserine readers and complement shape myeloid sink capture and inflammatory output. Integrin, tetraspanin, and ICAM-1 nanoclusters influence avidity, organotropism, and immune suppression. At the BBB, endothelial HSPGs, LRP1, and transferrin receptor (TfR) support receptor-mediated uptake, motivating engineered ligands such as rabies virus glycoprotein-derived peptides, Angiopep-2, and TfR binders. However, endosomal escape remains a major kinetic barrier to nucleic acid delivery. We synthesize these principles across Alzheimer's disease, Parkinson's disease, amyotrophic lateral sclerosis, glioblastoma, and demyelinating disease, and outline design and assay standards needed to translate EV biology into safe, manufacturable CNS therapeutics.\n\nID: 42434351\nTitle: Region-specific Transcriptomic Signatures in Alzheimer's Disease: A Meta-analysis of Vulnerable Brain Regions Reveals MicroRNA-hub Gene Regulatory Networks.\nAbstract: Alzheimer's disease (AD) is characterized by progressive neurodegeneration in regionally vulnerable brain areas, yet molecular insights into early pathogenic mechanisms remain limited. We conducted a meta-analysis of transcriptomic datasets from brain regions affected in early-to-moderate AD - including entorhinal cortex, CA1 hippocampus, angular gyrus, and frontal cortex synaptoneurosomes - using data from seven mRNA and one microRNA (miRNA) microarray studies (GSE16759, GSE110226, GSE37264, GSE26972, GSE36980, GSE37263, GSE39420, and GSE157239). Preprocessing included background correction, log2 transformation, quantile normalization, and batch correction via ComBat. Differentially expressed features were defined as false discovery rate <0.05 and | logFC| ≥ 1.23 (genes) or ≥ 2 (miRNAs). We identified 172 differentially expressed genes (122 upregulated and 50 downregulated) and 82 significant miRNAs. Hub genes included Inositol-trisphosphate 3-kinase B (ITPKB), Synaptotagmin 1, Dystrobrevin alpha (DTNA), X Inactive Specific Transcript, and Regulator of G protein signaling 4 (RGS4). Functional enrichment highlighted calcium signaling, synaptic failure, and neuroinflammation. Notably, hsa-miR-30d-5p was predicted to target both ITPKB and DTNA, suggesting a regulatory axis linking miRNA dysregulation to calcium dyshomeostasis. Receiver operating characteristic analysis revealed that only RGS4 showed moderate discriminative capacity (area under the curve [AUC] =0.70), while other hub genes (e.g., ITPKB, AUC = 0.40) exhibited below-chance performance, underscoring the limitations of single-gene classifiers in postmortem tissue. This study provides mechanistic hypotheses - rather than diagnostic biomarkers - by uncovering region-specific, miRNA-mediated regulatory networks in AD-affected brain tissues. Future validation in accessible biofluids is essential before clinical translation.\n\nID: 42436002\nTitle: CAPNS1 restoration partially alleviates mitochondrial dysfunction and synaptic deficits in Alzheimer's disease through the Ca2⁺-CaMKIIβ-MAPK-PGC-1α axis.\nAbstract: Alzheimer's disease (AD), a progressive neurodegenerative disorder characterized by brain atrophy and cognitive decline. While the amyloid cascade hypothesis remains the dominant framework, accumulating evidence indicates that mitochondrial dysfunction critically contributes to AD progression. Although improving mitochondrial function has been shown to rescue cognitive deficits in AD models, the underlying molecular mechanisms remain elusive. In this study, we identified a significant reduction in calpain small subunit 1 (CAPNS1) expression in both AD patient samples and male transgenic mouse models. Decreased CAPNS1 levels were strongly correlated with mitochondrial ultrastructural damage, reduced mitochondrial DNA (mtDNA) copy number, and progressive synaptic loss. Mechanistically, we found that CAPNS1 positively regulated mtDNA transcription and mitochondrial gene expression, and pharmacological data suggested the involvement of the Ca2⁺-CaMKIIβ-MAPK-PGC-1α signaling axis, a master pathway governing mitochondrial biogenesis and respiratory capacity. This activation subsequently restored cellular ATP production and reduced mitochondrial reactive oxygen species accumulation. Importantly, neuronal-specific CAPNS1 upregulation in APP/PS1 transgenic mice markedly improved mitochondrial cristae integrity, reversed hippocampal long-term potentiation deficits, increased dendritic spine density, and partially alleviated spatial memory deficits in behavioral tests. We noted that loss-of-function experiments (e.g., CAPNS1 knockdown or knockout) were not performed in this study, and the proposed Ca2⁺-CaMKIIβ-MAPK-PGC-1α axis should therefore be interpreted as a suggestive working model requiring further validation. Collectively, our findings indicate that CAPNS1 serves as a key regulator of mitochondrial function. By linking Ca2⁺ signaling to mitochondrial gene expression and synaptic integrity, CAPNS1 represents a promising therapeutic target for ameliorating synaptic loss and cognitive decline in AD.\n\nID: 42435587\nTitle: Precision therapeutics and innovative clinical trial design in neurodegenerative diseases.\nAbstract: Neurodegenerative diseases are biologically heterogeneous disorders characterized by progressive neuronal dysfunction, overlapping molecular pathologies, and limited disease-modifying therapies. Advances in biomarker development, molecular staging, and precision medicine are reshaping therapeutic strategies and clinical trial design across Parkinson's disease, Alzheimer's disease, frontotemporal dementia, amyotrophic lateral sclerosis, Huntington's disease, and related disorders. This review summarizes emerging therapeutic approaches, including monoclonal antibodies targeting protein aggregation, immune-modulating and metabolic interventions, antisense oligonucleotides, gene replacement and genome-editing strategies, stem cell-based therapies, and neurosurgical delivery platforms and neuromodulation technologies. It also examines evolving clinical trial methodologies such as biomarker-enriched recruitment, adaptive and delayed-start designs, platform trials, decentralized models, and master protocols. Additional emphasis is placed on diagnostic biomarkers, multimodal artificial-intelligence pipelines, systems-biology perspectives, network-based therapeutic strategies, and the reproducibility and interpretability requirements for computational tools. Despite recent progress, major challenges remain, including biological heterogeneity, limited translatability of preclinical models, delivery barriers, long-term safety concerns, and inequities in access to biomarker-based care and trial participation. Future directions will require combination therapies, integrated biomarker pipelines, preventive strategies, and pragmatic trial systems capable of translating biological advances into durable and equitable clinical benefit.\n\nID: 42432671\nTitle: The role of AI-assisted drug repurposing in neurological disorders: a systematic review of validation strategies, challenges and opportunities.\nAbstract: Neurological disorders refer to a diverse group of conditions that affect the brain, peripheral nerves, and spinal cord and impair socioemotional, cognitive, motor, and sensory functions. Alzheimer's disease (AD), Multiple Sclerosis (MS), Parkinson's disease (PD), Huntington's disease (HD), and Amyotrophic Lateral Sclerosis (ALS) are some of the well-known neurodegenerative diseases that affect millions of people worldwide. Despite the advanced technologies and nano-drug delivery systems, the success rate of developing drugs for neurological disorders is significantly low. Among several constraints, including gastrointestinal irritation, rapid metabolism, and low stability, the blood-brain barrier (BBB) emerges as one of the key challenges in the development and application of drugs against neurological disorders. These challenges necessitate innovative approaches to develop cost-effective therapeutic strategies. Drug repurposing, the discovery of new therapeutic benefits of existing drugs, is a promising drug discovery approach for discovering potential treatment options for complex neurological disorders. This review aims to explore the advanced and significant progress in drug repurposing for major neurological disorders, including MS, AD, PD, ALS, HD, stroke, and neuropsychiatric conditions. It places an explicit emphasis on discussing the potential role of artificial intelligence (AI)-assisted drug repurposing and understanding of the biological mechanisms in discovering new drugs for these neurological conditions. This also examines current challenges in drug repurposing and provides a critical review of the available opportunities and limitations in AI-assisted drug repurposing.\n\nID: 42431966\nTitle: An interpretable multimodal framework using compact biomarkers and Kolmogorov-Arnold networks improves the early diagnosis of Alzheimer's disease.\nAbstract: Early diagnosis of Alzheimer's disease (AD), especially accurate identification at the mild cognitive impairment (MCI) stage, is crucial for slowing disease progression. Although deep learning has achieved promising performance in AD diagnosis, existing multimodal models often operate as \"black boxes,\" lacking the transparency required for clinical practice and failing to explicitly model deep interactions between imaging and clinical features. To address these limitations, this study proposes an interpretable multimodal framework, namely the Compact Biomarker Kolmogorov-Arnold Network (CBKAN). Specifically, we introduce EHCTNet with disease-specific attention to extract features from 3D MRI data, and innovatively constrain the encoder to output a set of compact biomarkers instead of traditional high-dimensional abstract vectors, mimicking the diagnostic logic of clinicians (e.g., judging brain atrophy). In addition, a hybrid feature Transformer is used to fuse these imaging biomarkers with clinical and genetic data, explicitly capturing complementary relationships across modalities. Finally, the Kolmogorov-Arnold Network (KAN) is adopted as the classifier to effectively model the highly nonlinear characteristics of AD progression. Experiments on 800 subjects from the ADNI dataset show that CBKAN achieves 91.1% accuracy and an F1-score of 0.910 in the AD/MCI/CN classification task, significantly outperforming existing mainstream methods. Statistical analyses validate the effectiveness of each component of the model. The proposed model provides a potentially interpretable and high-performing decision-support framework for early Alzheimer's disease diagnosis, although its cross-cohort generalizability and real-world clinical utility require further validation in independent external datasets.\n\nID: 42431913\nTitle: Novel approach to early prediction of alzheimer's disease progression using integrated deep regulatory genetic neural network and optimized deep belief networks.\nAbstract: To enhance the prediction progression of Alzheimer's Disease is very excavating process. It is often very difficult to implement in the chronic neurodegenerative disease-related preprocessed gene expression data. Especially, Alzheimer's Disease (AD) prediction is a very crucial process in AD metadata diagnosis. Novelty: To explore this challenging prediction process in brain disease prediction, this research presents a proposed deep learning model, namely the Integrated Deep Regulatory Genetic Neural Network and Optimised Deep Belief Networks (IDRODN). This integration increases the affluence of prediction progression from genomic data. These prediction systems help identify early AD. This research utilizes the IDRODN, which can predict and confine each network's neurons and hidden layers against the benchmark dataset of Alzheimer's gene expression and uncertainty to predict Alzheimer's Disease. The comparative analysis on data from the Alzheimer's disease gene expression data Initiative database has achieved an accuracy of 98.3%. In addition, it has achieved a high F1 score of 0.986 for predicting different stages from Gene expression data. This shows the most accurate technique for predicting Alzheimer's Disease (AD) using the prognostic IDRODN model.\n\nID: 42430077\nTitle: Targeting IL-33 in Precision Neuroimmunology: Cellular Mechanisms and Therapeutic Strategies for CNS Disorders.\nAbstract: Interleukin-33 (IL-33), an alarmin cytokine of the IL-1 family, has emerged as a pivotal regulator of neuroimmune interactions in the central nervous system (CNS). Acting through its receptor ST2, IL-33 orchestrates diverse immune responses by modulating microglial polarization, shaping T cell differentiation, activating type 2 innate lymphoid cells (ILC2s), and engaging mast cell-macrophage regulatory circuits. Across distinct neurological disorders, including epilepsy, stroke, traumatic brain injury (TBI), Parkinson's disease (PD), Alzheimer's disease (AD), multiple sclerosis (MS), cerebral malaria, and glioma, IL-33 exerts both protective and pathogenic effects in a context-dependent manner. In epilepsy, IL-33 modulates neuroinflammation and neuronal excitability; in stroke, it attenuates acute neurovascular injury while influencing post-stroke remodeling; in AD, it enhances amyloid-β clearance and mitigates chronic neuroinflammation; in MS, it regulates autoimmune demyelination via T cell and innate immune pathways. These shared yet disease-specific mechanisms underscore IL-33's central role in neuroimmune homeostasis and its potential as a precision therapeutic target. Future research integrating multi-disease models, temporal disease staging, and single-cell multi-omics will be essential to define the conditions under which IL-33 modulation yields maximal therapeutic benefit.\n\nID: 42429744\nTitle: SMDNet: A Self-Training-Aware and Multi-Modal-Adaptive Deep Learning Network for Low-Data Aβ42 Probe Design and Optimization.\nAbstract: Amyloid-β (Aβ) plaque accumulation is a crucial hallmark of Alzheimer's disease, and fluorescence imaging can support disease diagnosis and monitoring. However, Aβ42 probe development is often hindered by trial-and-error experiments due to subtle structure-property effects. Here, we developed SMDNet, a self-training-aware and multimodal-adaptive deep learning (DL) framework for low-data Aβ42 probe design and optimization. SMDNet combines iterative self-training with confidence-aware and distribution-aware sampling to improve data quality, while integrating molecular graphs, fingerprints and protein descriptors through cross-attention and protein-conditional adaptive layer normalization. Ablation studies, external validation and generalization analyses confirmed the strong predictive ability of SMDNet. Interpretability analyses further highlighted chemically meaningful substructures associated with model predictions. As a proof of concept, SMDNet guided the rational design of five ThT-derived probe candidates, with TA3 showing favorable binding affinity and high-contrast imaging performance. Additional validation on coumarin- and naphthalimide-based candidates further supported useful predictive discrimination across distinct fluorescent scaffold classes.\n\nID: 42428048\nTitle: Interpretable feature-transformer framework for cross-subject MCI detection using nonlinear dynamical and graph-theoretic EEG features.\nAbstract: Early and accurate detection of Mild Cognitive Impairment (MCI) is essential for preventing progression toward Alzheimer's disease (AD). In this cross-subject study, we investigate the effectiveness of entropy- and graph-based EEG features for distinguishing MCI from healthy controls (HC), using two modeling approaches: (1) a Transformer network applied to the engineered feature set, and (2) an EEGNet model trained on the same feature representation for comparison. The dataset consists of resting-state, eyes-closed EEG recordings from 183 participants (127 HC, 56 MCI), collected using a 20-channel STAT™ X24 wireless system and segmented into 3-second epochs. EEG data underwent standard preprocessing, including band-pass filtering, downsampling, normalization, and class-balancing augmentation applied to the minority class. From each channel, nonlinear dynamical measures (e.g., sample and fuzzy entropy, Higuchi fractal dimension, Lyapunov exponent) and graph-theoretic connectivity descriptors derived from coherence matrices across five frequency bands were extracted, yielding a structured 19[Formula: see text]77 feature representation. The feature-based Transformer achieved the best performance (97.04% ± 0.72), outperforming the feature-based EEGNet baseline and highlighting the benefits of combining rich handcrafted features with attention-based modeling. SHAP (SHapley Additive exPlanations) analysis provided global and local interpretability, revealing the most influential nonlinear and connectivity features as well as the EEG channels contributing most to classification. Overall, these results demonstrate the effectiveness of feature-Transformer integration and support the potential of interpretable feature-driven deep learning models for early MCI detection.\n\nID: 42428045\nTitle: Diagnosis of Alzheimer's disease from neuroimages using steerable quantum probabilistic hamiltonian generative modeling with adaptive chaotic satin bowerbird optimization.\nAbstract: Alzheimer's Disease (AD) is a disease of the brain that lowers quality of life due to cognitive impairment. A correct diagnosis is therefore essential for timely interventions and follow-up care for executives. However, existing deep learning methodologies for neuroimage-based diagnosis seriously lack reliability due to decreased accuracy and increased false positive rates, both of which can lead to misdiagnosis and suboptimal care planning. This study proposed an innovative Steerable Quantum Probabilistic Hamiltonian Generative Modeling with Adaptive Chaotic Satin Bowerbird Optimization (SQPHGM-ACSBO) framework for diagnosing AD using neuroimages within the ADNI dataset. A total of 5,154 neuroimages from the ADNI dataset were utilized in this study, comprising 2,590 MCI, 1,124 AD, and 1,440 cognitively normal (CN) samples. The process begins with image enhancement via an Adaptive Self-Guided Loop Filter, followed by precise brain region segmentation with GoogLeNet Inception-v3, and advanced feature extraction using a new Discrete Cosine-Krawtchouk-Tchebichef Transform (DCKTT). Classification is performed using the SQPHGM model, which combines the strengths of Steerable Transformers and Quantum-Probabilistic Hamiltonian Learning to model complex neuroimaging patterns, while the Adaptive Chaotic Satin Bowerbird Optimization (ACSBO) algorithm optimizes classification performance. With 99.9% accuracy and 99.8% precision, the suggested method outperforms current methods and provides a dependable, high-performance solution for AD diagnosis from neuroimaging data, according to experimental results. The main innovation of this work is the all-in-one optimization of steerable transformer-based directional feature learning, quantum-probabilistic Hamilton generator modeling, and adaptive-chaotic satin bowerbird optimization integrated within a single diagnostic pipeline, which allows for representing the complicated neuroimaging patterns better, and the convergence stability is also increased, compared to the previous deep learning-based Alzheimer diagnosis models.\n\nID: 42426901\nTitle: Emerging mechanisms and targeted therapy of PANoptosis in neurological diseases.\nAbstract: PANoptosis is a distinct inflammatory and lytic cell death pathway, orchestrated by the PANoptosome and executed through caspases and receptor-interacting protein kinases (RIPKs). Unlike other forms of programmed cell death, PANoptosis integrates components from multiple death signaling cascades. To date, several PANoptosome complexes - such as those nucleated by ZBP1, AIM2, RIPK1, and NLRP12 - have been characterized. These supramolecular assemblies form via domain-domain interactions upon detection of pathogen-associated or damage-associated signals. By eliminating infected and compromised cells, this coordinated pathway helps maintain tissue homeostasis, while its synchronized release of inflammatory cytokines and damage-associated molecular patterns (DAMPs) enhances innate immune responses, resulting in more effective pathogen clearance compared to any single cell death mechanism. Growing evidence underscores the relevance of PANoptosis across a spectrum of pathological conditions, including neurological disorders, infections, inflammatory diseases, cancer, and homeostatic imbalances, often mediated by PANoptosis-associated proteins. In neurological contexts - such as stroke, Parkinson's disease, Alzheimer's disease, and traumatic brain injury - PANoptosis activation correlates with disease progression and prognosis, highlighting its potential as a therapeutic target. In this review, we systematically outline the molecular foundations of PANoptosis, examine its role in neurological diseases, and summarize current pharmacological and methodological strategies for its modulation. A deeper understanding of PANoptosis may inform the identification of novel therapeutic targets for neurological disorders.\n\nID: 42423667\nTitle: A nose-to-brain drug delivery system targeting mitochondrial dysfunction: application potential and future prospects of chitosan nanogels in Alzheimer's disease.\nAbstract: Alzheimer's disease (AD) is a neurodegenerative disorder characterized by neuronal degeneration and cognitive impairment. One of its core pathologies involves energy metabolism disruption and oxidative stress resulting from mitochondrial dysfunction. Traditional drugs struggle to effectively cross the blood-brain barrier (BBB), while the nasal-brain drug delivery system offers a novel approach for achieving direct brain access. Chitosan, a biodegradable natural polymer with strong mucosal adhesion properties, has been extensively utilized in recent years to construct nanogel carriers. This approach enhances drug retention and absorption in the nasal epithelium, enabling targeted delivery to the brain via the olfactory or trigeminal nerve pathways. This paper provides a systematic review of research progress on chitosan nanogel-based naso-cerebral drug delivery systems targeting mitochondrial dysfunction, focusing on their molecular mechanisms in improving mitochondrial energy metabolism, scavenging excess reactive oxygen species (ROS), suppressing neuroinflammation, and regulating apoptosis. Additionally, this paper analyzes the design principles of various modification strategies-such as triphenylphosphine (TPP) modification, pH/ROS responsiveness, and drug-loaded nanozyme complexes-along with their efficacy validation in AD models. It further explores the future development trends of chitosan nanogel-mediated multi-target intervention and smart-responsive nasal-brain delivery systems, offering new directions for precision treatment of AD.\n\nID: 42422561\nTitle: Brain age gradients as intermediate phenotypes linking plasma p-tau217 to cognition in community-dwelling older adults.\nAbstract: Deep learning-based brain age models quantify regional deviations from normative aging and may capture structural changes relevant to dementia risk. Plasma phosphorylated tau-217 (p-tau217) is a scalable Alzheimer's disease biomarker, but its relationship to brain aging and cognition in cognitively unimpaired adults is unclear. In this cross-sectional study, we tested whether brain age patterns serve as indirect pathways linking plasma p-tau217 to cognition in the Aging Brain Cohort (ABC). Neuroimaging data from 518 adults (mean age = 43.7 years, 70.8% female) were analyzed using a validated deep learning brain age model, and decomposed via exploratory factor analysis into six gradients: frontal, dorsal, ventral, left frontotemporal, right frontotemporoparietal, and bilateral parietal. In a parallel mediation model including all six gradients as simultaneous mediators in adults aged ≥60 years (N = 71), a significant specific indirect effect of plasma p-tau217 on Montreal Cognitive Assessment (MoCA) scores was observed through accelerated right frontotemporoparietal aging (β = -0.111, 95% CI [-0.313, -0.010], p = 0.031). No other indirect pathways were significant, and neither the total nor direct effect was significant. These findings suggest a specific brain aging phenotype as a potential intermediate pathway linking tau-related pathology to cognition prior to clinical impairment.\n\nID: 42420222\nTitle: Effects of Metabolites of Lactic Acid Bacteria on Nerve Cells of the Microbiota-Gut-Brain Axis.\nAbstract: This review examines the key pathways of bidirectional communication between the gut and brain along the microbiota-gut-brain axis, with particular emphasis on the effects of metabolites of lactic acid bacteria (metLABs) on neurons of the enteric and central nervous systems. Special attention is given to the role of metLABs in intracellular signaling. The review further explores the direct effects of metLABs on mitochondrial function in nervous tissue, neuronal plasticity, and neuritogenesis. Potential mechanisms for the release of neurotrophic factors in both cells and host organism following exposure to metLABs or probiotic products are analyzed. Although clinical evidence remains limited, existing studies suggest that regular consumption of metLAB-containing fermented foods may positively influence brain functions through modulation of the microbiota-gut-brain axis. At least two ongoing clinical trials currently investigate whether normalization of the gut microbiota through probiotic interventions can slow the progression of Alzheimer's disease. As this field continues to advance rapidly, further studies are expected to provide important insights into the therapeutic potential of microbiota-targeted strategies for neurological health.\n\nID: 42419611\nTitle: Nose-to-brain delivery of an amyloid beta blocking peptide using polylactic acid-poloxamer 188 nanocarriers.\nAbstract: Alzheimer's disease, characterized by a progressive cognitive decline, represents a major global health challenge. A novel blocking peptide (seq: KRKKSRYKSWSVYVG) which binds with high affinity for toxic amyloid beta oligomers implicated in the early stages of the disease pathogenesis, has shown promising therapeutic potential. To overcome the challenges of brain drug delivery, nanoparticles combined with a nose-to-brain delivery approach were used to enhance brain biodistribution and drug delivery efficiency. In this study, we evaluated the feasibility of using these nanoparticles to deliver the blocking peptide to the brain. Nanoparticles composed of polylactic acid and poloxamer P188 were synthesized and successfully functionalised with surface-adsorbed blocking peptide, exhibiting physicochemical characteristics suitable for nose-to-brain delivery. The nanoparticles preserved the blocking peptide therapeutic activity against amyloid beta aggregation and, in addition, protected it from enzymatic degradation. Functional cellular evaluation showed biocompatibility of the nanoparticle-blocking peptide compound and potential internalization by neuronal cells. Importantly, in vivo experiments demonstrated the successful delivery of the nanoparticles from the nasal cavity to the brain, representing a significant step forward in targeted brain delivery. Nanoparticles functionalised with an anti-amyloid beta aggregation peptide successfully reached the brain following intranasal administration, suggesting their potential as a therapeutic strategy against the Alzheimer's disease.\n\nID: 42418295\nTitle: Advances in the Core Role and Mechanisms of Mitochondrial Dysfunction in Alzheimer's Disease.\nAbstract: Alzheimer's disease (AD) is a complex neurodegenerative disorder whose pathogenesis involves multi-level pathological alterations. This review aims to systematically elucidate the central role and multifaceted molecular mechanisms of mitochondrial dysfunction in the progression of AD. A comprehensive analysis of the existing literature was conducted, synthesizing findings from studies investigating mitochondrial involvement in AD pathology. The review focused on key mechanistic pathways, including energy metabolism deficits, oxidative stress, synaptic damage, mitochondrial dynamics, mitochondria-associated membranes (MAMs), mitophagy, and the gut-brain axis. The analysis revealed several critical mechanisms linking mitochondrial dysfunction to AD progression: (i) impaired mitochondrial energy metabolism, which establishes a causal relationship with oxidative stress and synaptic injury; (ii) dysregulation of mitochondrial fusion/fission dynamics, particularly the aberrant interactions of amyloid-beta (Aβ) and p-Tau with the fission protein Drp1 and the channel protein VDAC1; (iii) dysfunction of mitochondria-associated membranes (MAMs); (iv) defective mitophagy involving both the PINK1/Parkin pathway and receptor-mediated pathways; and (v) bidirectional crosstalk between mitochondria and the gut-brain axis. These interconnected pathways converge to amplify neuroinflammation and neuronal death. Accumulated evidence positions mitochondrial dysfunction as a critical hub that integrates Aβ/Tau pathology, neuroinflammation, and neuronal loss, thereby perpetuating a self-sustaining vicious cycle in AD. Targeting mitochondrial bioenergetics, dynamics, quality control, and the mitochondria-inflammation axis offers substantial therapeutic promise. Emerging small molecules such as SS31 and DDQ have demonstrated protective effects in preclinical models. Future investigations should prioritize mechanistic dissection and translational research to facilitate the clinical development of mitochondria-targeted therapies for AD.\n\nID: 42413935\nTitle: Optimal control for anti-abeta treatment in Alzheimer's disease using a reaction-diffusion model.\nAbstract: Alzheimer's disease (AD) is a progressive neurodegenerative disorder that severely impairs survival and quality of life. While anti-amyloid beta (Aβ) therapies can slow disease progression, their efficacy depends on personalized dosing that maximizes benefits and minimizes risks, such as amyloid-related imaging abnormalities (ARIA). Mathematical modelling offers a powerful tool for understanding AD dynamics and optimizing treatment, yet most models focus solely on temporal behaviour, overlooking spatial heterogeneity within the brain. In this study, we propose a spatially explicit reaction-diffusion model to describe Aβ plaque dynamics. We formulate an optimal control problem to minimize plaque concentration while balancing therapeutic efficacy and treatment risk. Under reasonable assumptions, we establish well-posedness and uniqueness of the optimal solution. A finite element method (FEM)-based numerical framework is developed to compute personalized treatment strategies. Our model is calibrated using longitudinal Aβ positron emission tomography (PET) data from the Alzheimer's Disease Neuroimaging Initiative (ADNI), enabling estimation of patient-specific parameters, such as growth rate and effective diffusivity. Results show that optimized treatment strategies consistently outperform constant dosing regimens across patient groups, achieving substantial reductions in cumulative amyloid burden while minimizing side effects. This integrated, data-driven framework advances personalized, spatially informed therapeutic optimization for AD.\n\nID: 42413810\nTitle: Atrazine induces Alzheimer's disease-like neurotoxicity by targeting SDHB and disrupting synaptic function: An integrated bioinformatic and in vivo study.\nAbstract: Atrazine (ATR) is a globally prevalent herbicide linked to increased risks of cognitive impairment and neurodegeneration, but its molecular mechanism remains unclear. This study integrates bioinformatics, machine learning, and experimental validation to elucidate ATR induced Alzheimer's disease (AD)-like pathology. We combined predicted ATR targets with AD brain transcriptomics, identifying 32 shared genes enriched in neurodegeneration and synaptic signaling pathways. We constructed a diagnostic model using 14 machine learning algorithms; the ensemble model achieved an improved AUC of 0.891 in the training set, with external validation AUCs of 0.833, 0.869, and 0.900. SHAP interpretability analysis identified SDHB as the most important key risk factor. Molecular docking validated the stable binding between ATR and core target proteins, with binding energies ranging from -4.9 to -5.9 kcal/mol. Single-cell sequencing and in silico gene knockdown confirmed that SDHB deficiency primarily disrupts neuronal synaptic signaling pathways. In vivo experiments demonstrated that ATR exposure induces anxiety-like behavior and memory deficits, suppressed hippocampal SDHB, and elevated Aβ and p-tau levels. ATR also reduced synaptic markers PSD95 and SYP in a dose dependent manner, confirming SDHB suppression leads to synaptic damage. Based on these findings, we established the first standardized adverse outcome pathway (AOP) framework delineating the cascade of events from ATR-induced SDHB inhibition to cognitive impairment. This study demonstrates that ATR targets SDHB to induce synaptic dysfunction and AD-like neuropathology, offering a new mechanistic basis for environmental risk assessment.\n\nID: 42411221\nTitle: Phyto-Nanotherapeutics for Alzheimer's Disease: Current Progress and Future Perspectives.\nAbstract: Alzheimer's Disease (AD) is a prevalent neurodegenerative disorder characterized by progressive cognitive and behavioral impairment and represents a major cause of dementia worldwide. It primarily affects the elderly population. The disease is marked by progressive neuronal damage, leading to impairments in cognition, behavior, emotions, and communication. Although currently available therapies provide symptomatic relief, they fail to alter disease progression, necessitating the development of more effective therapeutic strategies. Phytoconstituents have gained considerable attention due to their neuroprotective properties and multitargeted mechanisms of action against pathways implicated in AD. However, their clinical application is limited by poor Blood-Brain Barrier (BBB) permeability, low bioavailability, and inadequate solubility. Nanotechnology offers a promising approach for brain-targeted drug delivery by enhancing the therapeutic efficacy of phytoconstituents through advanced nanocarrier systems. This review explores the synergistic potential of phytoconstituents and nanocarriers for the management of AD, aiming to improve therapeutic outcomes and overcome existing limitations. It further highlights the integration of medicinal plant-based compounds with nanotechnology as a novel strategy for AD treatment. The combination of nanocarriers and phytoconstituents may facilitate enhanced BBB penetration and improved neuroprotection. Notably, nanomedicine- based approaches, including phytoconstituent-loaded nanoparticles and liposomes, demonstrate significant potential to overcome delivery barriers and enable efficient drug transport to the brain.\n\nID: 42410536\nTitle: Comparative evaluation of automated MRI-based brain volumetry software for estimating cognitive domains in early Alzheimer's disease.\nAbstract: Brain volumetry software is widely accepted for assessment in Alzheimer's disease. However, direct comparisons for software-specific prediction capabilities across cognitive domains have not been reported. This study evaluates the performance of four brain volumetry software programs in predicting domain-specific cognitive scores in patients with early Alzheimer's disease (AD) using a consistent deep learning model. A total of 255 patients with amyloid PET-confirmed AD were retrospectively enrolled. Brain volumetric features were extracted from 3D T1-weighted MRI using four software programs (AQUA, DeepBrain, A-finder, and FreeSurfer). A multi-layer perceptron model incorporating seven clinical variables and software-specific volumetric features was trained to predict six cognitive outcomes: the Mini-Mental State Examination (MMSE) score and five Seoul Neuropsychological Screening Battery (SNSB) domain scores. Model performance was evaluated using mean squared error and Pearson's correlation coefficient (r). The FreeSurfer-based model showed the numerically highest correlation for MMSE (r = 0.56), language (r = 0.38), visuospatial (r = 0.21), and frontal/executive functions (r = 0.32). The AQUA-based model showed the numerically highest correlation for attention (r = 0.40), and DeepBrain for memory (r = 0.38). MMSE scores were generally better predicted than domain-specific scores across all models. Brain volumetry software showed modest, domain-dependent associations with cognitive scores in early AD, with the strongest signal for MMSE and no statistically significant prediction for visuospatial function. These findings support the potential of brain volumetry software to partially estimate domain-level cognitive profiles, while differences across software should be interpreted with caution rather than as evidence of intrinsic software superiority.\n\nID: 42409055\nTitle: Adversarial attacks on a multimodal Alzheimer's disease detection system reveal complex interdependences between heterogeneous modalities.\nAbstract: Multi-modal models that fuse neuroimaging with clinical assessment data represent the current state of the art for automated Alzheimer's disease detection, yet their adversarial robustness remains poorly understood. We systematically investigated adversarial vulnerability in CogniNetMM, a model that fuses 3D structural MRI volumes with neuropsychological clinical variables, using the Fast Gradient Sign Method and DeepFool in three modality configurations: MRI only, clinical variables only, and both jointly. We further introduced a mean attack framework, in which the average perturbation vector across samples serves as a fixed-direction probe of the decision boundary, decoupling the contribution of attack direction from that of sample position.During training, we identified modality collapse, a training instability in which the fusion layer progressively suppresses the MRI pathway. Collapse probability decreased with larger batch sizes and was further reduced by stratified sampling on class-imbalanced data. Across all clinical variable configurations and both attack methods, the joint multi-modal attack achieved higher success than the average of the two unimodal attacks. For DeepFool, the advantage was strong enough that the joint attack outperformed each unimodal attack individually near the decision boundary. The mean attack replicated this result under a fixed perturbation direction, confirming that the advantage is a structural property of the fused decision boundary rather than an artifact of per-sample gradient alignment. These findings are consistent with a concave original-class region in the joint input space: non-linear modality coupling creates adversarially reachable regions that neither modality perturbation can access independently. Together, these results show that heterogeneous data fusion introduces emergent adversarial vulnerabilities beyond what unimodal analysis predicts, and that standard training practices on imbalanced medical datasets carry a risk of silent modality suppression.\n\nID: 42407324\nTitle: From DNA-encoded library (DEL) screening to in vivo validation: LILRB4 (ILT3)-targeted small molecules reprograms myeloid immune suppression.\nAbstract: Alzheimer's disease (AD) remains a major unmet clinical challenge, with limited therapeutic strategies capable of effectively modulating neuroimmune dysfunction. Leukocyte immunoglobulin-like receptor B4 (LILRB4/ILT3) has recently emerged as an inhibitory microglial immune checkpoint implicated in ApoE-mediated suppression of amyloid-β (Aβ) clearance and inflammatory signaling, supporting its potential as a therapeutic target in AD. Here, we applied DNA-encoded library (DEL) screening of approximately 3.6 billion compounds to identify small molecule binders of LILRB4. Biophysical validation identified APX1 as a direct LILRB4 ligand with submicromolar affinity, which was further confirmed by cellular thermal shift assay (CETSA). Docking-guided mutagenesis studies defined a discrete ligand-binding interface involving key hotspot residues required for stable target engagement. Functionally, APX1 disrupted the LILRB4-ApoE interaction in orthogonal ELISA and biolayer interferometry assays. In human iPSC-derived microglia, APX1 suppressed SHP1/2 phosphorylation, attenuated NF-κB activation and IL-1β secretion, and restored Aβ42 uptake under ApoE-driven inflammatory conditions. APX1 further demonstrated favorable in vitro developability, metabolic stability, and CNS exposure properties. In the 5xFAD mouse model of AD, oral administration of APX1 improved cognitive performance, reduced cortical and hippocampal Aβ42 burden, suppressed neuroinflammatory cytokines, and decreased activated microglial populations. Collectively, these findings establish APX1 as a promising small molecule modulator of the LILRB4-ApoE signaling axis and support pharmacological targeting of neuroimmune checkpoints as a therapeutic strategy for AD.\n\nID: 42406553\nTitle: EphB1-Mediated Transient Blood-Brain Barrier Opening Facilitates a Ferritin-Based Nanotherapeutic for Alzheimer's Disease.\nAbstract: The treatment of Alzheimer's disease (AD) is severely hampered by the blood-brain barrier (BBB), which limits the delivery of therapeutic agents like donepezil (DPZ), an acetylcholinesterase inhibitor. While DPZ has multi-faceted benefits, its clinical efficacy is constrained by poor BBB penetration, requiring high doses that lead to significant side effects. To overcome this, we developed a brain-targeted nanotherapeutic utilizing apoferritin (AFn) nanoparticles loaded with DPZ (AFn-DPZ). We demonstrate that this platform, by binding to the EphB1 receptor on the blood-brain barrier, enables transient and reversible opening of the blood-brain barrier, thereby facilitating efficient and targeted drug delivery. Following intravenous administration in an AD mouse model, AFn-DPZ exhibited enhanced brain accumulation and sustained release of DPZ. This targeted delivery inhibited acetylcholinesterase activity, reduced amyloid plaque burden, alleviated neuroinflammation, attenuated oxidative damage, restored mitochondrial function, and upregulated the expression of brain-derived neurotrophic factor (BDNF). Consequently, AFn-DPZ treatment significantly improved cognitive performance compared to free DPZ. Our findings establish EphB1-mediated facilitation of BBB traversal as a promising strategy for enhancing nanotherapeutic delivery to the brain, offering a potent approach to address the complex pathology of AD.\n\nID: 42406259\nTitle: Tetrapeptide inhibitors of BACE-1 revealed by combined data-driven screening and physics-based free-energy refinement.\nAbstract: Alzheimer's disease remains a major global health challenge, and β-site amyloid precursor protein cleaving enzyme 1 (BACE-1) represents a critical therapeutic target as it catalyzes the rate-limiting step in amyloid-β production. While computational studies have extensively explored small-molecule BACE-1 inhibitors, large-scale screening combined with physics-based refinement has rarely been applied to peptide scaffolds. Here, we report an integrated machine learning (ML)-to- free energy perturbation (FEP) pipeline, combining XGBoost-based screening, molecular docking, replicate explicit-solvent molecular dynamics (MD), and absolute FEP calculations, as a multi-stage alternative to single-scoring approaches for tetrapeptide lead discovery against BACE-1. Screening a library of 16,000 tetrapeptides with an XGBoost model prioritized four candidates (HWRE, HWER, WHRR, and HWRQ) for structure-based evaluation. Molecular docking confirmed favorable positioning within the catalytic cleft, while replicate MD simulations revealed multivalent binding through hydrogen bonds, salt bridges to the catalytic dyad (Asp32/Asp228), and hydrophobic contacts with conserved pocket residues; interaction-fingerprint and hotspot analyses provided residue-level guidance for optimization. FEP calculations delivered quantitative thermodynamic ranking, separating three strong predicted binders (HWRE, WHRR, HWRQ; ΔGFEP = - 29.45 to - 32.00 kcal mol-1) from the weaker candidate HWER (ΔGFEP = - 14.78 kcal mol-1). The three high-affinity peptides share a conserved H/W/R motif with persistent dyad anchoring and dense hydrogen-bond networks, a compact scaffold amenable to peptidomimetic optimization, with HWRE as the top lead across all computational stages. This study delivers experimentally testable tetrapeptide candidate inhibitors and establishes a scalable framework for peptide-based ligand discovery against BACE-1 and related aspartyl proteases.\n\nID: 42400785\nTitle: Detection of Chimeric RNAs from RNA-Seq Data with ChiTaRS 8.0: Insights for Liquid Biopsy and Drug Target Identification.\nAbstract: Chimeric RNAs (chiRNAs), generated via genomic rearrangements or splicing events, are increasingly recognized as biomarkers and therapeutic targets in cancer and neurodegenerative disorders. This chapter introduces an integrative framework for high-confidence chiRNA identification leveraging the ChiTaRS 8.0 database and the ChiTaH pipeline. ChiTaRS 8.0 encompasses 47,445 human chiRNAs, 1,055 Hi-C breakpoints, and 1,598 drug targets, while ChiTaH facilitates disease-specific analysis of RNA-seq data from 250 peripheral blood mononuclear cell (PBMC) samples-including glioblastoma and oral squamous cell carcinoma-and 199 healthy controls. Our approach combines reference-based fusion detection, BLAT validation against GRCh38, gene-pair compatibility checks, and protein domain conservation analysis. Functional annotation and protein-protein interaction modeling uncovered oncogenic chiRNAs absent from existing databases, exhibiting tissue-specific patterns. In Alzheimer's disease, liquid biopsy analyses identified unique chimeras-such as ENO1-MCUR1 and APOE-APOE-in cerebrospinal fluid, linked to neurotransmitter pathways and amyloid processing, and absent in healthy samples, highlighting their potential as early biomarkers. We describe a scalable digital hospital framework integrating AI-driven fusion detection, relational databases, and clinical metadata for real-time diagnostics and patient monitoring. This system supports fusion-targeted drug discovery and patient stratification, bridging translational gaps in oncology and neurodegeneration. By coupling computational pipelines with multiomics data, our approach advances personalized medicine while addressing challenges in artifact filtering and functional validation. Ultimately, the ChiTaRS-ChiTaH platform offers a versatile tool for chiRNA discovery and annotation across diverse disease contexts, providing insights into molecular mechanisms and clinical applications.\n\nID: 42400646\nTitle: Beyond complex architectures: a streamlined CNN pipeline for robust Alzheimer's disease classification from brain MRI.\nAbstract: Alzheimer's disease, a common type of dementia, gradually steals memories and impacts daily life as brain cells deteriorate. We explored how Artificial Intelligence (AI) could help spot early signs of Alzheimer's using MRI brain scans. Our study focused on a deep learning approach, specifically a convolutional neural network (CNN), to distinguish between Alzheimer's, Mild Cognitive Impairment (MCI), and healthy individuals. We used two well-known datasets, OASIS and ADNI, for this work. After carefully preparing the ADNI data (which included 21,324 MRI images: 7,572 from MCI patients, 5,904 from healthy controls, and 7,848 from Alzheimer's patients) and the OASIS data (6,400 MRI images), our model performed exceptionally well. The CNN Model achieved an accuracy of 99.67% with the ADNI images and 99.06% with the OASIS images. These encouraging results, which stand up well against other studies, show that our method can effectively analyze large amounts of data and accurately classify Alzheimer's. Our main hope is that this kind of technology can give doctors and caregivers better tools to predict and detect the disease, ultimately saving time, reducing costs, and helping those affected by Alzheimer's.\n\nID: 42400119\nTitle: EXPRESS: Toll Like Receptor 4 (TLR4) in Neuroinflammation: From Acute Hemorrhagic Stroke to Chronic Neurodegeneration.\nAbstract: Subarachnoid Hemorrhage (SAH) remains a leading cause of morbidity and mortality worldwide. While the primary injury is defined by mechanical tissue disruption, the progression of secondary brain injury is largely driven by robust neuroinflammatory cascades initiated by blood derived damage-associated molecular patterns (DAMPs). Among the key mediators of this response, Toll-like receptor 4 (TLR4) has emerged as a central regulator. TLR4 activation in microglia triggers downstream signaling through both MyD88 dependent and TRIF dependent pathways, driving the production of pro inflammatory cytokines and type I interferons. Additionally, non-canonical regulation of TLR4 by Lyn kinase introduces a critical modulatory mechanism that can shift microglial responses between inflammatory and phagocytic phenotypes in a sex dependent manner. Beyond hemorrhagic stroke, TLR4 mediated neuroinflammation also plays a significant role in the progression of Alzheimer's disease, where it influences amyloid-β recognition, clearance, and chronic glial activation. Emerging therapeutic strategies targeting TLR4 and its downstream signaling components including small molecules, natural compounds, aptamers, and TLR4-Lyn interaction modulators demonstrate promising potential in attenuating neuroinflammation and improving neurological outcomes. This review highlights the molecular mechanisms of TLR4 signaling in neuroinflammation and underscores its translational relevance as a therapeutic target in both acute and chronic neurodegenerative conditions.\n\nID: 42398843\nTitle: Segmentation of the parasagittal dura mater on multi-center 3D-FLAIR MRI.\nAbstract: The parasagittal dura (PSD), located bilaterally alongside the superior sagittal sinus (SSS), has been increasingly implicated in cerebrospinal fluid-meningeal lymphatic communication, contributing to CSF waste clearance and immune surveillance. We assembled a training set of 55 3D-Fluid-Attenuated Inversion Recovery (3D-FLAIR) scans from Alzheimer's Disease Neuroimaging Initiative(ADNI) and local datasets to train an nnU-Net-based model for automated PSD segmentation (mcPSD-Net). Segmentation performance was assessed against manual ground truth in an independent test set (N = 25) containing images acquired from various scanners. Three voxel overlap metrics (DICE, Precision and Recall) and three surface distance metrics (HD, HD95, ASSD) were used to evaluate the accuracy of the mcPSD-Net. Multiple linear regression models were performed to evaluate the associations of PSD volume (normalized by intracranial volume) with age, and sex in the whole ADNI3 dataset and a local community dataset. In the testing dataset, mcPSD-Net achieved good performance (Dice coefficient=0.76; precision=0.84; recall=0.73; HD=21.42 mm; HD95=4.00 mm; ASSD=0.53 mm). Regression analyses demonstrated that PSD volume increased significantly with age in both the ADNI3 (standardized β = 0. 390, p < 0.001) and local community dataset (standardized β = 0. 307, p < 0.001). Compared to females, males had a significantly larger PSD volume in both datasets (p < 0.001 for all). Furthermore, including scanner vendor as a covariate did not improve model fitting in the ADNI3 dataset. In summary, we developed a deep learning model that segments PSD from 3D-FLAIR images acquired using different vendors and imaging protocols, providing a tool for related clinical imaging studies.\n\nID: 42398801\nTitle: HDAC11 as a potential therapeutic target for Alzheimer's disease.\nAbstract: Alzheimer's disease (AD) is the leading cause of dementia. It is characterized by amyloid and tau pathological hallmarks, accompanied by synaptic dysfunction, neuroinflammation, and progressive neuronal loss. Although amyloid-reducing antibodies have recently expanded the disease-modifying therapeutic options, no disease-modifying small-molecule therapeutics are currently available for AD. Epigenetic regulators, particularly histone deacetylases (HDACs), have attracted increasing attention as potential therapeutic targets. Among them, HDAC2, 3 and 6 are supported by broad AD-related evidence, whereas HDAC11 has emerged as a mechanistically distinct potential target. As the sole class IV HDAC and a relatively brain-enriched but not brain-specific lysine defatty-acylase, HDAC11 connects lipid metabolism, innate immunity, microglial function, neuroinflammation, and AD-associated pathology. We discuss advances in HDAC11 biology and AD-related pathology, position HDAC11 among other established AD-relevant HDAC isoforms, and discuss progress relating to HDAC11-selective inhibitors. We pay particular attention to target druggability, chemical probe development, blood-brain barrier penetration, pharmacokinetics, safety and off-target liabilities, and translational promise. In summary, HDAC11 is an emerging therapeutic target in AD, but future studies are needed for chemical optimization, for pathological validation using other disease models, and to show safety and efficacy in the AD context.\n=======================================================\n\n### [CUSTOM DATAPOINTS]\nCRITICAL EXTRACTION DIRECTIVE: You MUST extract the following custom datapoints as root-level key/value pairs inside your final JSON block:\n- \"suggested_experiments\": generate 1-3 suggested experiments\n- \"suggested_studies\": generate 1-3 suggested studies\n- \"swansons_literature_based_discovery_candidates\": You are an advanced Literature-Based Discovery (LBD) system executing Swanson’s complementary-but-disjoint (A-B-C) model.

However, the application of natural exosomes is constrained by their poor targeting ability. Herein, we report a novel drug delivery system (P2-Exo-Cur) constructed by engineering exosomes to display the P2 peptide on their surface, thereby enabling targeted delivery of curcumin to microglia. Our results revealed that P2-Exo-Cur possesses a nanoscale membrane structure and can efficiently deliver curcumin to microglia both in vitro and in vivo. This technology provides a microglia-targeted delivery approach for anti-inflammatory agents such as curcumin, while overcoming the undesirable off-target effects that limit their efficacy. Furthermore, treatment of lipopolysaccharide (LPS)-induced inflammatory BV2 cell models with P2-Exo-Cur significantly suppressed the polarization of BV2 cells toward the M1 phenotype, as well as the secretion of pro-inflammatory cytokines. Finally, we also validated the excellent therapeutic potential of this technology in the 5xFAD mouse model. In conclusion, in this study, we for the first time constructed engineered exosomes that can specifically bind to the NCAM protein on microglia to achieve precise delivery of curcumin by expressing the P2 peptide on their surface, exerting beneficial effects in AD treatment without causing significant adverse effects. This strategy may offer a non-invasive and innovative therapeutic method for the management of brain inflammation-related diseases.\n  --- END ACTUAL ABSTRACT FOR 42440589 ---\n\n- ERROR: You cited ID: 42431966 for the quote: \"Experiments on 800 subjects from the ADNI dataset show that CBKAN achieves 91.1% accuracy and an F1-score of 0.910 in the AD/MCI/CN classification task.\"\n  FACT: Strict Misquote Detected!

Although deep learning has achieved promising performance in AD diagnosis, existing multimodal models often operate as \"black boxes,\" lacking the transparency required for clinical practice and failing to explicitly model deep interactions between imaging and clinical features. To address these limitations, this study proposes an interpretable multimodal framework, namely the Compact Biomarker Kolmogorov-Arnold Network (CBKAN). Specifically, we introduce EHCTNet with disease-specific attention to extract features from 3D MRI data, and innovatively constrain the encoder to output a set of compact biomarkers instead of traditional high-dimensional abstract vectors, mimicking the diagnostic logic of clinicians (e.g., judging brain atrophy). In addition, a hybrid feature Transformer is used to fuse these imaging biomarkers with clinical and genetic data, explicitly capturing complementary relationships across modalities. Finally, the Kolmogorov-Arnold Network (KAN) is adopted as the classifier to effectively model the highly nonlinear characteristics of AD progression. Experiments on 800 subjects from the ADNI dataset show that CBKAN achieves 91.1% accuracy and an F1-score of 0.910 in the AD/MCI/CN classification task, significantly outperforming existing mainstream methods. Statistical analyses validate the effectiveness of each component of the model. The proposed model provides a potentially interpretable and high-performing decision-support framework for early Alzheimer's disease diagnosis, although its cross-cohort generalizability and real-world clinical utility require further validation in independent external datasets.\n  --- END ACTUAL ABSTRACT FOR 42431966 ---\n\n- ERROR: You cited ID: 42439628 for the quote: \"Recent evidence suggests that PU.1-low CD28-positive microglia may restrain neuroinflammation and amyloid pathology.\"\n  FACT: Strict Misquote Detected!

Genetic, single-cell, and spatial studies have shown that Alzheimer 's-associated microglia occupy diverse disease-linked states shaped by amyloid plaques, tau pathology, lipid stress, complement activation, astrocyte signaling, aging, and immune genetic risk. Among the regulatory nodes controlling these states, SPI1, which encodes the myeloid transcription factor PU.1, has emerged as a key determinant of microglial identity and disease responsiveness. Human genetic studies suggest that reduced SPI1 expression may be protective, whereas experimental data indicate that excessive PU.1 suppression can impair essential microglial functions. This review examines the emerging concept that partial, plaque-associated reduction in PU.1 may enable a distinct lymphoid-like immunoregulatory microglial program marked by CD28 expression. Recent evidence suggests that PU.1-low CD28-positive microglia may restrain neuroinflammation and amyloid pathology, raising the possibility that Alzheimer's plaques induce not only inflammatory and phagocytic microglial responses, but also endogenous suppressive programs that limit tissue damage. We discuss this proposed PU.1/CD28 regulatory axis in relation to disease-associated microglia, TREM2-APOE signaling, complement-mediated synapse loss, antigen-presentation pathways, plaque-niche biology, and therapeutic microglial reprogramming. We also highlight major unresolved questions, including whether PU.1-low CD28-positive microglia are present and functional in human Alzheimer's disease, whether they are specific to amyloid-rich niches or extend to tau and mixed pathologies, and how such states could be safely manipulated without disrupting essential immune surveillance. We propose that lymphoid-like suppressive microglia represent a promising but still unproven framework for understanding protective neuroimmune regulation in Alzheimer's disease and for developing state-specific microglial therapies.\n  --- END ACTUAL ABSTRACT FOR 42439628 ---\n\n- ERROR: You cited ID: 42435703 for the quote: \"It concludes that bromo-vanillyl carbamate derivative 5c (30 mg/kg) has potent antioxidant, anti-amyloid, and neuroprotective characteristics, rendering it a promising multitarget lead.\"\n  FACT: Strict Misquote Detected!

Oxidative damage, alterations of brain glucose metabolism, and cognitive impairment are all demonstrated in the STZ models. In order to overcome such effects, a new set of phenolic-carbamate conjugates (5a-5h) was synthesized, and their structures were elucidated using FTIR, UV, and NMR spectroscopy. The in silico studies confirmed excellent binding capabilities against AChE and Aβ targets. In vitro antioxidant assays depicted a significant free radical scavenging ability, with compound 5c exhibiting the enhanced effect. Cell line study with SH-SY5Y and PC12 cells showed greater % cell viability. AChE activity demonstrated compound 5c has significant effectiveness (IC50 = 1.98 uM). Neurobehavioral activity showed an improvement in learning and memory during behavioural assessments. In vivo antioxidant study showed greater scavenging activity (SOD, CAT, GSH), reduced of oxidative stress (MDA, NO), and the improvement in total antioxidant activity. Overall, the compound 5c has demonstrated significant results comprising decreased cholinesterase and Aβ inhibition deciphering enhanced cholinergic restoration. Hippocampal integrity was preserved, as it was confirmed by histopathological examination. It concludes that bromo-vanillyl carbamate derivative 5c (30 mg/kg) has potent antioxidant, anti-amyloid, and neuroprotective characteristics, rendering it a promising multitarget lead that warrants further investigation for the treatment of AD.\n  --- END ACTUAL ABSTRACT FOR 42435703 ---\n\n- ERROR: You cited ID: 4243390 for the quote: \"Administration of this peptide effectively suppressed GSK3β activation and mitigated tauopathy and neurodegeneration in both in vitro and in vivo models.\"\n  FACT: Invalid Source ID.

Emerging studies suggest that LIG may have therapeutic relevance in central nervous system (CNS) disorders. This review systematically summarizes the pharmacological effects, molecular mechanisms, pharmacokinetic characteristics, metabolism, safety profile, and therapeutic potential of LIG in CNS disorders. Relevant studies published up to 26 October 2025 were retrieved from PubMed, Web of Science, and Scopus using keywords related to ligustilide, central nervous system disorders, pharmacokinetics, metabolism, and toxicity. After removing duplicate records and excluding reviews, editorials, and irrelevant articles, 55 eligible original studies were included in this review. Current evidence indicates that LIG exerts neuroprotective effects in multiple CNS disorders, including ischemic stroke, cerebral ischemia-reperfusion injury, vascular dementia, Alzheimer's disease, Parkinson's disease, traumatic brain injury, and anxiety disorders. Its mechanisms mainly involve modulation of PI3K/Akt, MAPK, NF-κB, Nrf2/ARE, AMPK, and other signaling pathways, leading to reduced oxidative stress, inflammation, apoptosis, and mitochondrial dysfunction. In addition, available studies suggest that LIG can cross the blood-brain barrier and shows relatively favorable safety in preclinical models. LIG demonstrates broad neuroprotective potential in preclinical studies and may represent a promising candidate for CNS disease intervention. However, its poor chemical stability, low oral bioavailability, limited toxicity evaluation, and lack of clinical evidence remain major challenges for translational application. Further studies are required to optimize delivery strategies and validate its efficacy and safety in clinical settings.\n  --- END ACTUAL ABSTRACT FOR 42440665 ---\n\n\n✅ PASSED (DO NOT CHANGE THESE):\n- \"We propose the Stage-State-Space Neuroimmune Reprogramming Model (S3-NRM), aligning AD immunotherapy with disease stage, glial/endotype state, and spatial inflammatory niche, guided by fluid, imaging, and omics biomarkers.\" (Source: 42439681)\n- \"Lecanemab and donanemab are anti-amyloid-β (Aβ) monoclonal antibodies recently approved for the treatment of Alzheimer's disease (AD).\" (Source: 42440686)\n- \"This shows the most accurate technique for predicting Alzheimer's Disease (AD) using the prognostic IDRODN model.\" (Source: 42431913)\n- \"Functionally, APX1 disrupted the LILRB4-ApoE interaction in orthogonal ELISA and biolayer interferometry assays.\" (Source: 42407324)\n- \"Functionally, IB15C disrupted the ILT3-ApoE interaction and restored microglial activity in human iPSC-derived microglia, reducing SHP1/2 and NF-κB signaling, suppressing IL-1β secretion, and enhancing Aβ uptake.\" (Source: 42445022)\n- \"Apremilast (APR), an FDA-approved, orally bioavailable phosphodiesterase-4 (PDE4) inhibitor, has recently emerged as a favorable drug repurposing candidate capable of elevating intracellular cAMP and triggering a cascade of neuroprotective mechanisms.\" (Source: 42432263)\n- \"In the APP/PS1 transgenic mouse model of AD, trazodone treatment enhanced microglial interaction with Aβ and alleviated Aβ pathology.\" (Source: 42446992)\n- \"Our findings establish EphB1-mediated facilitation of BBB traversal as a promising strategy for enhancing nanotherapeutic delivery to the brain, offering a potent approach to address the complex pathology of AD.\" (Source: 42406553)\n- \"The strongest disproportionality reporting signals were mainly observed for ARIA-related preferred terms and cerebral microhaemorrhage.\" (Source: 42440686)\n- \"These results reveal reduced deep sleep and PV-associated 40-Hz activity as very early changes amenable to early intervention occurring prior to cognitive deficits.\" (Source: 42427748)\n- \"Mechanistically, this dysfunction is affected by aging, astroglial aquaporin-4 (AQP4) depolarization, vascular impairment, sleep abnormalities, oxidative damage, and neuroinflammation.\" (Source: 42430835)\n- \"Our findings demonstrate that Fc effector function is indispensable for microglial-mediated amyloid clearance in vivo.\" (Source: 42444752)\n- \"Integrating preclinical and clinical evidence, we propose an \"APOE4-associated peripheral-central immune infiltration cascade\" as a unifying framework for understanding systemic AD pathogenesis.\" (Source: 42435996)\n- \"Baseline antidepressant use was linked to a higher risk of dementia, poorer cognitive performance, and adverse brain structural changes.\" (Source: 42438861)\n\n\nINSTRUCTION: Study the actual abstracts provided.

Mirroring human disease, POWV strain LI9 directs age-dependent lethality in C57BL/6 (B6) mice, resulting in spongiform encephalitis, gliosis, and inflammatory cytokine/chemokine responses in the CNS. However, the mechanisms underlying age-dependent lethality and persistent neurodegenerative disease in POWV survivors remain to be resolved. Here, we analyzed cellular CNS responses to POWV LI9 infection in young (10-week-old) and aged (50-week-old) mice using single-cell RNA sequencing. Infection of young mice resulted in inflammatory CNS infiltrates (NK, CD4/CD8 T cells, and monocytes) and interferon responses that coincide with peak viral burden. In contrast, the CNS of aged infected mice instead featured upregulated astrocyte and neuronal genes associated with neurodegenerative and Alzheimer's disease pathways and the transition of homeostatic microglia to a Trem2-ApoE-linked disease-associated microglial transcriptional state. Histological analysis revealed that amyloid precursor protein (APP)/amyloid-β (Aβ) accumulated in the CNS following POWV infection and that POWV envelope protein and APP/Aβ were selectively localized within layers L5/L6 of the cerebral cortex. POWV kinetically increased perinuclear APP/Aβ accumulation during acute infection and was highly expressed in the CNS of POWV survivors. Our findings reveal that POWV triggers glial cell responses and a neurodegenerative disease-associated microglia program of Alzheimer's-like APP/Aβ accumulation in mice, which is consistent with long-term neurological sequelae in human POWV survivors.IMPORTANCEPowassan virus (POWV) causes lethal encephalitis and long-term cognitive deficits in survivors. Using an age-dependent murine model, we reveal that POWV-infected young mice direct robust CNS inflammatory infiltrates associated with viral clearance, whereas aged mice exhibit impaired immune responses and a shift from homeostatic to neurodegenerative glial cell states. POWV prompted the induction of disease-associated microglia (DAM) and Trem2-ApoE axis transcriptional responses that are hallmarks of APP/amyloid-β (Aβ) accumulation in Alzheimer's disease (AD). Remarkably, POWV induced progressive APP/Aβ accumulation in young and aged mice that persisted in survivors after viral clearance. This suggests that POWV induces an APP/Aβ neurodegenerative process and provides a potential cause of long-term neurological sequelae observed in human POWV survivors. Our data suggest that POWV initiates or exacerbates AD-like neuropathology and further rationalizes investigating the role of APP/Aβ responses in other encephalitic viruses.\n  --- END ACTUAL ABSTRACT FOR 42446869 ---\n\n\n✅ PASSED (DO NOT CHANGE THESE):\n- \"Lecanemab and donanemab are anti-amyloid-β (Aβ) monoclonal antibodies recently approved for the treatment of Alzheimer's disease (AD).\" (Source: 42440686)\n- \"The strongest disproportionality reporting signals were mainly observed for ARIA-related preferred terms and cerebral microhaemorrhage.\" (Source: 42440686)\n- \"The median TTO was 46 days for lecanemab and 31 days for donanemab, and Weibull analysis suggested different temporal patterns of AE occurrence.\" (Source: 42440686)\n- \"We propose the Stage-State-Space Neuroimmune Reprogramming Model (S3-NRM), aligning AD immunotherapy with disease stage, glial/endotype state, and spatial inflammatory niche, guided by fluid, imaging, and omics biomarkers.\" (Source: 42439681)\n- \"Apremilast (APR), an FDA-approved, orally bioavailable phosphodiesterase-4 (PDE4) inhibitor, has recently emerged as a favorable drug repurposing candidate capable of elevating intracellular cAMP and triggering a cascade of neuroprotective mechanisms.\" (Source: 42432263)\n- \"Functionally, IB15C disrupted the ILT3-ApoE interaction and restored microglial activity in human iPSC-derived microglia, reducing SHP1/2 and NF-κB signaling, suppressing IL-1β secretion, and enhancing Aβ uptake.\" (Source: 42445022)\n- \"Functionally, APX1 disrupted the LILRB4-ApoE interaction in orthogonal ELISA and biolayer interferometry assays.\" (Source: 42407324)\n- \"In the APP/PS1 transgenic mouse model of AD, trazodone treatment enhanced microglial interaction with Aβ and alleviated Aβ pathology.\" (Source: 42446992)\n- \"These results reveal reduced deep sleep and PV-associated 40-Hz activity as very early changes amenable to early intervention occurring prior to cognitive deficits.\" (Source: 42427748)\n- \"Mechanistically, this dysfunction is affected by aging, astroglial aquaporin-4 (AQP4) depolarization, vascular impairment, sleep abnormalities, oxidative damage, and neuroinflammation.\" (Source: 42430835)\n- \"Our findings demonstrate that Fc effector function is indispensable for microglial-mediated amyloid clearance in vivo.\" (Source: 42444752)\n- \"Integrating preclinical and clinical evidence, we propose an \"APOE4-associated peripheral-central immune infiltration cascade\" as a unifying framework for understanding systemic AD pathogenesis.\" (Source: 42435996)\n- \"Baseline antidepressant use was linked to a higher risk of dementia, poorer cognitive performance, and adverse brain structural changes.\" (Source: 42438861)\n- \"Our findings establish EphB1-mediated facilitation of BBB traversal as a promising strategy for enhancing nanotherapeutic delivery to the brain, offering a potent approach to address the complex pathology of AD.\" (Source: 42406553)\n- \"This shows the most accurate technique for predicting Alzheimer's Disease (AD) using the prognostic IDRODN model.\" (Source: 42431913)\n- \"Specifically, the single amino acid substitutions A30W, K28A, and M35C can reduce the aggregation and toxicity of the Aβ42 peptide.\" (Source: 42444987)\n- \"Intact mitophagy facilitates the timely clearance of damaged mitochondria, thereby limiting the release of mitochondrial DAMPs (e.g., mtDNA and mtROS) and helping restrain aberrant activation of the cGAS-STING pathway and the NLRP3 inflammasome.\" (Source: 42443967)\n- \"Experiments on 800 subjects from the ADNI dataset show that CBKAN achieves 91.1% accuracy and an F1-score of 0.910 in the AD/MCI/CN classification task, significantly outperforming existing mainstream methods.\" (Source: 42431966)\n- \"Overall, the compound 5c has demonstrated significant results comprising decreased cholinesterase and Aβ inhibition deciphering enhanced cholinergic restoration.\" (Source: 42435703)\n\n\nINSTRUCTION: Study the actual abstracts provided.

This synthesis evaluates the emergence of next-generation therapeutic candidates, advanced machine-learning diagnostic pipelines, and systemic metabolic/immune mechanisms that modulate disease progression.\n\n### [INTRODUCTION & JUSTIFICATION]\nModern AD research has moved beyond the traditional amyloid-only hypothesis to address the multifactorial nature of the disease, including bioenergetic failure, neuroimmune dysfunction, and synaptic impairment. Immunotherapy, specifically via anti-amyloid monoclonal antibodies like lecanemab and donanemab, has shifted the clinical landscape, though safety profiles regarding amyloid-related imaging abnormalities remain critical areas of monitoring. Simultaneously, researchers are pioneering the \"Stage-State-Space Neuroimmune Reprogramming Model,\" which emphasizes the importance of aligning treatments with the specific inflammatory niche and glial state of the patient. Breakthroughs in drug delivery—such as nanocarriers that enable blood-brain barrier traversal—and artificial intelligence-driven diagnostic tools are bridging the gap between bench-side molecular discovery and clinical implementation.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Emerging \"Stage-State-Space\" models suggest neuroinflammation is spatially organized and cell-state-specific rather than a target for broad suppression.\n*   Artificial intelligence-driven frameworks, such as the Compact Biomarker Kolmogorov-Arnold Network (CBKAN), are providing transparent, non-black-box diagnostic pathways for AD classification.\n*   Peripheral-central immune axes, mediated by APOE4, reveal that systemic immune homeostasis directly impacts CNS neurodegeneration.\n*   Fc-mediated effector function of antibodies is now definitively recognized as essential for microglia-mediated plaque clearance, differentiating the efficacy of nanobodies from Fc-fused constructs.\n*   Single-cell sequencing of virus-infected murine models (Powassan virus) indicates that infectious agents may trigger progressive Alzheimer’s-like APP/Aβ accumulation that persists even after viral clearance.\n*   Glymphatic dysfunction is increasingly identified as an early driver of neurodegeneration, exacerbated by sleep abnormalities and astroglial AQP4 depolarization.\n*   Pharmacological agents like trazodone and apremilast are being successfully repurposed to address immune dysfunction, cAMP-PI3K signaling, and synaptic integrity.\n*   Novel liquid biopsy techniques, including those utilizing chimeric RNAs identified by the ChiTaRS 8.0/ChiTaH pipeline, are proving valuable for early detection.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

It is characterized by amyloid and tau pathological hallmarks, accompanied by synaptic dysfunction, neuroinflammation, and progressive neuronal loss. Although amyloid-reducing antibodies have recently expanded the disease-modifying therapeutic options, no disease-modifying small-molecule therapeutics are currently available for AD. Epigenetic regulators, particularly histone deacetylases (HDACs), have attracted increasing attention as potential therapeutic targets. Among them, HDAC2, 3 and 6 are supported by broad AD-related evidence, whereas HDAC11 has emerged as a mechanistically distinct potential target. As the sole class IV HDAC and a relatively brain-enriched but not brain-specific lysine defatty-acylase, HDAC11 connects lipid metabolism, innate immunity, microglial function, neuroinflammation, and AD-associated pathology. We discuss advances in HDAC11 biology and AD-related pathology, position HDAC11 among other established AD-relevant HDAC isoforms, and discuss progress relating to HDAC11-selective inhibitors. We pay particular attention to target druggability, chemical probe development, blood-brain barrier penetration, pharmacokinetics, safety and off-target liabilities, and translational promise. In summary, HDAC11 is an emerging therapeutic target in AD, but future studies are needed for chemical optimization, for pathological validation using other disease models, and to show safety and efficacy in the AD context.","42398843":"ID: 42398843\nTitle: Segmentation of the parasagittal dura mater on multi-center 3D-FLAIR MRI.\nAbstract: The parasagittal dura (PSD), located bilaterally alongside the superior sagittal sinus (SSS), has been increasingly implicated in cerebrospinal fluid-meningeal lymphatic communication, contributing to CSF waste clearance and immune surveillance. We assembled a training set of 55 3D-Fluid-Attenuated Inversion Recovery (3D-FLAIR) scans from Alzheimer's Disease Neuroimaging Initiative(ADNI) and local datasets to train an nnU-Net-based model for automated PSD segmentation (mcPSD-Net). Segmentation performance was assessed against manual ground truth in an independent test set (N = 25) containing images acquired from various scanners. Three voxel overlap metrics (DICE, Precision and Recall) and three surface distance metrics (HD, HD95, ASSD) were used to evaluate the accuracy of the mcPSD-Net. Multiple linear regression models were performed to evaluate the associations of PSD volume (normalized by intracranial volume) with age, and sex in the whole ADNI3 dataset and a local community dataset. In the testing dataset, mcPSD-Net achieved good performance (Dice coefficient=0.76; precision=0.84; recall=0.73; HD=21.42 mm; HD95=4.00 mm; ASSD=0.53 mm). Regression analyses demonstrated that PSD volume increased significantly with age in both the ADNI3 (standardized β = 0. 390, p < 0.001) and local community dataset (standardized β = 0. 307, p < 0.001). Compared to females, males had a significantly larger PSD volume in both datasets (p < 0.001 for all). Furthermore, including scanner vendor as a covariate did not improve model fitting in the ADNI3 dataset. In summary, we developed a deep learning model that segments PSD from 3D-FLAIR images acquired using different vendors and imaging protocols, providing a tool for related clinical imaging studies.","42400119":"ID: 42400119\nTitle: EXPRESS: Toll Like Receptor 4 (TLR4) in Neuroinflammation: From Acute Hemorrhagic Stroke to Chronic Neurodegeneration.\nAbstract: Subarachnoid Hemorrhage (SAH) remains a leading cause of morbidity and mortality worldwide. While the primary injury is defined by mechanical tissue disruption, the progression of secondary brain injury is largely driven by robust neuroinflammatory cascades initiated by blood derived damage-associated molecular patterns (DAMPs). Among the key mediators of this response, Toll-like receptor 4 (TLR4) has emerged as a central regulator. TLR4 activation in microglia triggers downstream signaling through both MyD88 dependent and TRIF dependent pathways, driving the production of pro inflammatory cytokines and type I interferons. Additionally, non-canonical regulation of TLR4 by Lyn kinase introduces a critical modulatory mechanism that can shift microglial responses between inflammatory and phagocytic phenotypes in a sex dependent manner. Beyond hemorrhagic stroke, TLR4 mediated neuroinflammation also plays a significant role in the progression of Alzheimer's disease, where it influences amyloid-β recognition, clearance, and chronic glial activation. Emerging therapeutic strategies targeting TLR4 and its downstream signaling components including small molecules, natural compounds, aptamers, and TLR4-Lyn interaction modulators demonstrate promising potential in attenuating neuroinflammation and improving neurological outcomes. This review highlights the molecular mechanisms of TLR4 signaling in neuroinflammation and underscores its translational relevance as a therapeutic target in both acute and chronic neurodegenerative conditions.","42400646":"ID: 42400646\nTitle: Beyond complex architectures: a streamlined CNN pipeline for robust Alzheimer's disease classification from brain MRI.\nAbstract: Alzheimer's disease, a common type of dementia, gradually steals memories and impacts daily life as brain cells deteriorate. We explored how Artificial Intelligence (AI) could help spot early signs of Alzheimer's using MRI brain scans. Our study focused on a deep learning approach, specifically a convolutional neural network (CNN), to distinguish between Alzheimer's, Mild Cognitive Impairment (MCI), and healthy individuals. We used two well-known datasets, OASIS and ADNI, for this work. After carefully preparing the ADNI data (which included 21,324 MRI images: 7,572 from MCI patients, 5,904 from healthy controls, and 7,848 from Alzheimer's patients) and the OASIS data (6,400 MRI images), our model performed exceptionally well. The CNN Model achieved an accuracy of 99.67% with the ADNI images and 99.06% with the OASIS images. These encouraging results, which stand up well against other studies, show that our method can effectively analyze large amounts of data and accurately classify Alzheimer's. Our main hope is that this kind of technology can give doctors and caregivers better tools to predict and detect the disease, ultimately saving time, reducing costs, and helping those affected by Alzheimer's.","42400785":"ID: 42400785\nTitle: Detection of Chimeric RNAs from RNA-Seq Data with ChiTaRS 8.0: Insights for Liquid Biopsy and Drug Target Identification.\nAbstract: Chimeric RNAs (chiRNAs), generated via genomic rearrangements or splicing events, are increasingly recognized as biomarkers and therapeutic targets in cancer and neurodegenerative disorders. This chapter introduces an integrative framework for high-confidence chiRNA identification leveraging the ChiTaRS 8.0 database and the ChiTaH pipeline. ChiTaRS 8.0 encompasses 47,445 human chiRNAs, 1,055 Hi-C breakpoints, and 1,598 drug targets, while ChiTaH facilitates disease-specific analysis of RNA-seq data from 250 peripheral blood mononuclear cell (PBMC) samples-including glioblastoma and oral squamous cell carcinoma-and 199 healthy controls. Our approach combines reference-based fusion detection, BLAT validation against GRCh38, gene-pair compatibility checks, and protein domain conservation analysis. Functional annotation and protein-protein interaction modeling uncovered oncogenic chiRNAs absent from existing databases, exhibiting tissue-specific patterns. In Alzheimer's disease, liquid biopsy analyses identified unique chimeras-such as ENO1-MCUR1 and APOE-APOE-in cerebrospinal fluid, linked to neurotransmitter pathways and amyloid processing, and absent in healthy samples, highlighting their potential as early biomarkers. We describe a scalable digital hospital framework integrating AI-driven fusion detection, relational databases, and clinical metadata for real-time diagnostics and patient monitoring. This system supports fusion-targeted drug discovery and patient stratification, bridging translational gaps in oncology and neurodegeneration. By coupling computational pipelines with multiomics data, our approach advances personalized medicine while addressing challenges in artifact filtering and functional validation. Ultimately, the ChiTaRS-ChiTaH platform offers a versatile tool for chiRNA discovery and annotation across diverse disease contexts, providing insights into molecular mechanisms and clinical applications.","42406259":"ID: 42406259\nTitle: Tetrapeptide inhibitors of BACE-1 revealed by combined data-driven screening and physics-based free-energy refinement.\nAbstract: Alzheimer's disease remains a major global health challenge, and β-site amyloid precursor protein cleaving enzyme 1 (BACE-1) represents a critical therapeutic target as it catalyzes the rate-limiting step in amyloid-β production. While computational studies have extensively explored small-molecule BACE-1 inhibitors, large-scale screening combined with physics-based refinement has rarely been applied to peptide scaffolds. Here, we report an integrated machine learning (ML)-to- free energy perturbation (FEP) pipeline, combining XGBoost-based screening, molecular docking, replicate explicit-solvent molecular dynamics (MD), and absolute FEP calculations, as a multi-stage alternative to single-scoring approaches for tetrapeptide lead discovery against BACE-1. Screening a library of 16,000 tetrapeptides with an XGBoost model prioritized four candidates (HWRE, HWER, WHRR, and HWRQ) for structure-based evaluation. Molecular docking confirmed favorable positioning within the catalytic cleft, while replicate MD simulations revealed multivalent binding through hydrogen bonds, salt bridges to the catalytic dyad (Asp32/Asp228), and hydrophobic contacts with conserved pocket residues; interaction-fingerprint and hotspot analyses provided residue-level guidance for optimization. FEP calculations delivered quantitative thermodynamic ranking, separating three strong predicted binders (HWRE, WHRR, HWRQ; ΔGFEP = - 29.45 to - 32.00 kcal mol-1) from the weaker candidate HWER (ΔGFEP = - 14.78 kcal mol-1). The three high-affinity peptides share a conserved H/W/R motif with persistent dyad anchoring and dense hydrogen-bond networks, a compact scaffold amenable to peptidomimetic optimization, with HWRE as the top lead across all computational stages. This study delivers experimentally testable tetrapeptide candidate inhibitors and establishes a scalable framework for peptide-based ligand discovery against BACE-1 and related aspartyl proteases.","42406553":"ID: 42406553\nTitle: EphB1-Mediated Transient Blood-Brain Barrier Opening Facilitates a Ferritin-Based Nanotherapeutic for Alzheimer's Disease.\nAbstract: The treatment of Alzheimer's disease (AD) is severely hampered by the blood-brain barrier (BBB), which limits the delivery of therapeutic agents like donepezil (DPZ), an acetylcholinesterase inhibitor. While DPZ has multi-faceted benefits, its clinical efficacy is constrained by poor BBB penetration, requiring high doses that lead to significant side effects. To overcome this, we developed a brain-targeted nanotherapeutic utilizing apoferritin (AFn) nanoparticles loaded with DPZ (AFn-DPZ). We demonstrate that this platform, by binding to the EphB1 receptor on the blood-brain barrier, enables transient and reversible opening of the blood-brain barrier, thereby facilitating efficient and targeted drug delivery. Following intravenous administration in an AD mouse model, AFn-DPZ exhibited enhanced brain accumulation and sustained release of DPZ. This targeted delivery inhibited acetylcholinesterase activity, reduced amyloid plaque burden, alleviated neuroinflammation, attenuated oxidative damage, restored mitochondrial function, and upregulated the expression of brain-derived neurotrophic factor (BDNF). Consequently, AFn-DPZ treatment significantly improved cognitive performance compared to free DPZ. Our findings establish EphB1-mediated facilitation of BBB traversal as a promising strategy for enhancing nanotherapeutic delivery to the brain, offering a potent approach to address the complex pathology of AD.","42407324":"ID: 42407324\nTitle: From DNA-encoded library (DEL) screening to in vivo validation: LILRB4 (ILT3)-targeted small molecules reprograms myeloid immune suppression.\nAbstract: Alzheimer's disease (AD) remains a major unmet clinical challenge, with limited therapeutic strategies capable of effectively modulating neuroimmune dysfunction. Leukocyte immunoglobulin-like receptor B4 (LILRB4/ILT3) has recently emerged as an inhibitory microglial immune checkpoint implicated in ApoE-mediated suppression of amyloid-β (Aβ) clearance and inflammatory signaling, supporting its potential as a therapeutic target in AD. Here, we applied DNA-encoded library (DEL) screening of approximately 3.6 billion compounds to identify small molecule binders of LILRB4. Biophysical validation identified APX1 as a direct LILRB4 ligand with submicromolar affinity, which was further confirmed by cellular thermal shift assay (CETSA). Docking-guided mutagenesis studies defined a discrete ligand-binding interface involving key hotspot residues required for stable target engagement. Functionally, APX1 disrupted the LILRB4-ApoE interaction in orthogonal ELISA and biolayer interferometry assays. In human iPSC-derived microglia, APX1 suppressed SHP1/2 phosphorylation, attenuated NF-κB activation and IL-1β secretion, and restored Aβ42 uptake under ApoE-driven inflammatory conditions. APX1 further demonstrated favorable in vitro developability, metabolic stability, and CNS exposure properties. In the 5xFAD mouse model of AD, oral administration of APX1 improved cognitive performance, reduced cortical and hippocampal Aβ42 burden, suppressed neuroinflammatory cytokines, and decreased activated microglial populations. Collectively, these findings establish APX1 as a promising small molecule modulator of the LILRB4-ApoE signaling axis and support pharmacological targeting of neuroimmune checkpoints as a therapeutic strategy for AD.","42409055":"ID: 42409055\nTitle: Adversarial attacks on a multimodal Alzheimer's disease detection system reveal complex interdependences between heterogeneous modalities.\nAbstract: Multi-modal models that fuse neuroimaging with clinical assessment data represent the current state of the art for automated Alzheimer's disease detection, yet their adversarial robustness remains poorly understood. We systematically investigated adversarial vulnerability in CogniNetMM, a model that fuses 3D structural MRI volumes with neuropsychological clinical variables, using the Fast Gradient Sign Method and DeepFool in three modality configurations: MRI only, clinical variables only, and both jointly. We further introduced a mean attack framework, in which the average perturbation vector across samples serves as a fixed-direction probe of the decision boundary, decoupling the contribution of attack direction from that of sample position.During training, we identified modality collapse, a training instability in which the fusion layer progressively suppresses the MRI pathway. Collapse probability decreased with larger batch sizes and was further reduced by stratified sampling on class-imbalanced data. Across all clinical variable configurations and both attack methods, the joint multi-modal attack achieved higher success than the average of the two unimodal attacks. For DeepFool, the advantage was strong enough that the joint attack outperformed each unimodal attack individually near the decision boundary. The mean attack replicated this result under a fixed perturbation direction, confirming that the advantage is a structural property of the fused decision boundary rather than an artifact of per-sample gradient alignment. These findings are consistent with a concave original-class region in the joint input space: non-linear modality coupling creates adversarially reachable regions that neither modality perturbation can access independently. Together, these results show that heterogeneous data fusion introduces emergent adversarial vulnerabilities beyond what unimodal analysis predicts, and that standard training practices on imbalanced medical datasets carry a risk of silent modality suppression.","42410536":"ID: 42410536\nTitle: Comparative evaluation of automated MRI-based brain volumetry software for estimating cognitive domains in early Alzheimer's disease.\nAbstract: Brain volumetry software is widely accepted for assessment in Alzheimer's disease. However, direct comparisons for software-specific prediction capabilities across cognitive domains have not been reported. This study evaluates the performance of four brain volumetry software programs in predicting domain-specific cognitive scores in patients with early Alzheimer's disease (AD) using a consistent deep learning model. A total of 255 patients with amyloid PET-confirmed AD were retrospectively enrolled. Brain volumetric features were extracted from 3D T1-weighted MRI using four software programs (AQUA, DeepBrain, A-finder, and FreeSurfer). A multi-layer perceptron model incorporating seven clinical variables and software-specific volumetric features was trained to predict six cognitive outcomes: the Mini-Mental State Examination (MMSE) score and five Seoul Neuropsychological Screening Battery (SNSB) domain scores. Model performance was evaluated using mean squared error and Pearson's correlation coefficient (r). The FreeSurfer-based model showed the numerically highest correlation for MMSE (r = 0.56), language (r = 0.38), visuospatial (r = 0.21), and frontal/executive functions (r = 0.32). The AQUA-based model showed the numerically highest correlation for attention (r = 0.40), and DeepBrain for memory (r = 0.38). MMSE scores were generally better predicted than domain-specific scores across all models. Brain volumetry software showed modest, domain-dependent associations with cognitive scores in early AD, with the strongest signal for MMSE and no statistically significant prediction for visuospatial function. These findings support the potential of brain volumetry software to partially estimate domain-level cognitive profiles, while differences across software should be interpreted with caution rather than as evidence of intrinsic software superiority.","42411221":"ID: 42411221\nTitle: Phyto-Nanotherapeutics for Alzheimer's Disease: Current Progress and Future Perspectives.\nAbstract: Alzheimer's Disease (AD) is a prevalent neurodegenerative disorder characterized by progressive cognitive and behavioral impairment and represents a major cause of dementia worldwide. It primarily affects the elderly population. The disease is marked by progressive neuronal damage, leading to impairments in cognition, behavior, emotions, and communication. Although currently available therapies provide symptomatic relief, they fail to alter disease progression, necessitating the development of more effective therapeutic strategies. Phytoconstituents have gained considerable attention due to their neuroprotective properties and multitargeted mechanisms of action against pathways implicated in AD. However, their clinical application is limited by poor Blood-Brain Barrier (BBB) permeability, low bioavailability, and inadequate solubility. Nanotechnology offers a promising approach for brain-targeted drug delivery by enhancing the therapeutic efficacy of phytoconstituents through advanced nanocarrier systems. This review explores the synergistic potential of phytoconstituents and nanocarriers for the management of AD, aiming to improve therapeutic outcomes and overcome existing limitations. It further highlights the integration of medicinal plant-based compounds with nanotechnology as a novel strategy for AD treatment. The combination of nanocarriers and phytoconstituents may facilitate enhanced BBB penetration and improved neuroprotection. Notably, nanomedicine- based approaches, including phytoconstituent-loaded nanoparticles and liposomes, demonstrate significant potential to overcome delivery barriers and enable efficient drug transport to the brain.","42413810":"ID: 42413810\nTitle: Atrazine induces Alzheimer's disease-like neurotoxicity by targeting SDHB and disrupting synaptic function: An integrated bioinformatic and in vivo study.\nAbstract: Atrazine (ATR) is a globally prevalent herbicide linked to increased risks of cognitive impairment and neurodegeneration, but its molecular mechanism remains unclear. This study integrates bioinformatics, machine learning, and experimental validation to elucidate ATR induced Alzheimer's disease (AD)-like pathology. We combined predicted ATR targets with AD brain transcriptomics, identifying 32 shared genes enriched in neurodegeneration and synaptic signaling pathways. We constructed a diagnostic model using 14 machine learning algorithms; the ensemble model achieved an improved AUC of 0.891 in the training set, with external validation AUCs of 0.833, 0.869, and 0.900. SHAP interpretability analysis identified SDHB as the most important key risk factor. Molecular docking validated the stable binding between ATR and core target proteins, with binding energies ranging from -4.9 to -5.9 kcal/mol. Single-cell sequencing and in silico gene knockdown confirmed that SDHB deficiency primarily disrupts neuronal synaptic signaling pathways. In vivo experiments demonstrated that ATR exposure induces anxiety-like behavior and memory deficits, suppressed hippocampal SDHB, and elevated Aβ and p-tau levels. ATR also reduced synaptic markers PSD95 and SYP in a dose dependent manner, confirming SDHB suppression leads to synaptic damage. Based on these findings, we established the first standardized adverse outcome pathway (AOP) framework delineating the cascade of events from ATR-induced SDHB inhibition to cognitive impairment. This study demonstrates that ATR targets SDHB to induce synaptic dysfunction and AD-like neuropathology, offering a new mechanistic basis for environmental risk assessment.","42413935":"ID: 42413935\nTitle: Optimal control for anti-abeta treatment in Alzheimer's disease using a reaction-diffusion model.\nAbstract: Alzheimer's disease (AD) is a progressive neurodegenerative disorder that severely impairs survival and quality of life. While anti-amyloid beta (Aβ) therapies can slow disease progression, their efficacy depends on personalized dosing that maximizes benefits and minimizes risks, such as amyloid-related imaging abnormalities (ARIA). Mathematical modelling offers a powerful tool for understanding AD dynamics and optimizing treatment, yet most models focus solely on temporal behaviour, overlooking spatial heterogeneity within the brain. In this study, we propose a spatially explicit reaction-diffusion model to describe Aβ plaque dynamics. We formulate an optimal control problem to minimize plaque concentration while balancing therapeutic efficacy and treatment risk. Under reasonable assumptions, we establish well-posedness and uniqueness of the optimal solution. A finite element method (FEM)-based numerical framework is developed to compute personalized treatment strategies. Our model is calibrated using longitudinal Aβ positron emission tomography (PET) data from the Alzheimer's Disease Neuroimaging Initiative (ADNI), enabling estimation of patient-specific parameters, such as growth rate and effective diffusivity. Results show that optimized treatment strategies consistently outperform constant dosing regimens across patient groups, achieving substantial reductions in cumulative amyloid burden while minimizing side effects. This integrated, data-driven framework advances personalized, spatially informed therapeutic optimization for AD.","42418295":"ID: 42418295\nTitle: Advances in the Core Role and Mechanisms of Mitochondrial Dysfunction in Alzheimer's Disease.\nAbstract: Alzheimer's disease (AD) is a complex neurodegenerative disorder whose pathogenesis involves multi-level pathological alterations. This review aims to systematically elucidate the central role and multifaceted molecular mechanisms of mitochondrial dysfunction in the progression of AD. A comprehensive analysis of the existing literature was conducted, synthesizing findings from studies investigating mitochondrial involvement in AD pathology. The review focused on key mechanistic pathways, including energy metabolism deficits, oxidative stress, synaptic damage, mitochondrial dynamics, mitochondria-associated membranes (MAMs), mitophagy, and the gut-brain axis. The analysis revealed several critical mechanisms linking mitochondrial dysfunction to AD progression: (i) impaired mitochondrial energy metabolism, which establishes a causal relationship with oxidative stress and synaptic injury; (ii) dysregulation of mitochondrial fusion/fission dynamics, particularly the aberrant interactions of amyloid-beta (Aβ) and p-Tau with the fission protein Drp1 and the channel protein VDAC1; (iii) dysfunction of mitochondria-associated membranes (MAMs); (iv) defective mitophagy involving both the PINK1/Parkin pathway and receptor-mediated pathways; and (v) bidirectional crosstalk between mitochondria and the gut-brain axis. These interconnected pathways converge to amplify neuroinflammation and neuronal death. Accumulated evidence positions mitochondrial dysfunction as a critical hub that integrates Aβ/Tau pathology, neuroinflammation, and neuronal loss, thereby perpetuating a self-sustaining vicious cycle in AD. Targeting mitochondrial bioenergetics, dynamics, quality control, and the mitochondria-inflammation axis offers substantial therapeutic promise. Emerging small molecules such as SS31 and DDQ have demonstrated protective effects in preclinical models. Future investigations should prioritize mechanistic dissection and translational research to facilitate the clinical development of mitochondria-targeted therapies for AD.","42419611":"ID: 42419611\nTitle: Nose-to-brain delivery of an amyloid beta blocking peptide using polylactic acid-poloxamer 188 nanocarriers.\nAbstract: Alzheimer's disease, characterized by a progressive cognitive decline, represents a major global health challenge. A novel blocking peptide (seq: KRKKSRYKSWSVYVG) which binds with high affinity for toxic amyloid beta oligomers implicated in the early stages of the disease pathogenesis, has shown promising therapeutic potential. To overcome the challenges of brain drug delivery, nanoparticles combined with a nose-to-brain delivery approach were used to enhance brain biodistribution and drug delivery efficiency. In this study, we evaluated the feasibility of using these nanoparticles to deliver the blocking peptide to the brain. Nanoparticles composed of polylactic acid and poloxamer P188 were synthesized and successfully functionalised with surface-adsorbed blocking peptide, exhibiting physicochemical characteristics suitable for nose-to-brain delivery. The nanoparticles preserved the blocking peptide therapeutic activity against amyloid beta aggregation and, in addition, protected it from enzymatic degradation. Functional cellular evaluation showed biocompatibility of the nanoparticle-blocking peptide compound and potential internalization by neuronal cells. Importantly, in vivo experiments demonstrated the successful delivery of the nanoparticles from the nasal cavity to the brain, representing a significant step forward in targeted brain delivery. Nanoparticles functionalised with an anti-amyloid beta aggregation peptide successfully reached the brain following intranasal administration, suggesting their potential as a therapeutic strategy against the Alzheimer's disease.","42420222":"ID: 42420222\nTitle: Effects of Metabolites of Lactic Acid Bacteria on Nerve Cells of the Microbiota-Gut-Brain Axis.\nAbstract: This review examines the key pathways of bidirectional communication between the gut and brain along the microbiota-gut-brain axis, with particular emphasis on the effects of metabolites of lactic acid bacteria (metLABs) on neurons of the enteric and central nervous systems. Special attention is given to the role of metLABs in intracellular signaling. The review further explores the direct effects of metLABs on mitochondrial function in nervous tissue, neuronal plasticity, and neuritogenesis. Potential mechanisms for the release of neurotrophic factors in both cells and host organism following exposure to metLABs or probiotic products are analyzed. Although clinical evidence remains limited, existing studies suggest that regular consumption of metLAB-containing fermented foods may positively influence brain functions through modulation of the microbiota-gut-brain axis. At least two ongoing clinical trials currently investigate whether normalization of the gut microbiota through probiotic interventions can slow the progression of Alzheimer's disease. As this field continues to advance rapidly, further studies are expected to provide important insights into the therapeutic potential of microbiota-targeted strategies for neurological health.","42422561":"ID: 42422561\nTitle: Brain age gradients as intermediate phenotypes linking plasma p-tau217 to cognition in community-dwelling older adults.\nAbstract: Deep learning-based brain age models quantify regional deviations from normative aging and may capture structural changes relevant to dementia risk. Plasma phosphorylated tau-217 (p-tau217) is a scalable Alzheimer's disease biomarker, but its relationship to brain aging and cognition in cognitively unimpaired adults is unclear. In this cross-sectional study, we tested whether brain age patterns serve as indirect pathways linking plasma p-tau217 to cognition in the Aging Brain Cohort (ABC). Neuroimaging data from 518 adults (mean age = 43.7 years, 70.8% female) were analyzed using a validated deep learning brain age model, and decomposed via exploratory factor analysis into six gradients: frontal, dorsal, ventral, left frontotemporal, right frontotemporoparietal, and bilateral parietal. In a parallel mediation model including all six gradients as simultaneous mediators in adults aged ≥60 years (N = 71), a significant specific indirect effect of plasma p-tau217 on Montreal Cognitive Assessment (MoCA) scores was observed through accelerated right frontotemporoparietal aging (β = -0.111, 95% CI [-0.313, -0.010], p = 0.031). No other indirect pathways were significant, and neither the total nor direct effect was significant. These findings suggest a specific brain aging phenotype as a potential intermediate pathway linking tau-related pathology to cognition prior to clinical impairment.","42423667":"ID: 42423667\nTitle: A nose-to-brain drug delivery system targeting mitochondrial dysfunction: application potential and future prospects of chitosan nanogels in Alzheimer's disease.\nAbstract: Alzheimer's disease (AD) is a neurodegenerative disorder characterized by neuronal degeneration and cognitive impairment. One of its core pathologies involves energy metabolism disruption and oxidative stress resulting from mitochondrial dysfunction. Traditional drugs struggle to effectively cross the blood-brain barrier (BBB), while the nasal-brain drug delivery system offers a novel approach for achieving direct brain access. Chitosan, a biodegradable natural polymer with strong mucosal adhesion properties, has been extensively utilized in recent years to construct nanogel carriers. This approach enhances drug retention and absorption in the nasal epithelium, enabling targeted delivery to the brain via the olfactory or trigeminal nerve pathways. This paper provides a systematic review of research progress on chitosan nanogel-based naso-cerebral drug delivery systems targeting mitochondrial dysfunction, focusing on their molecular mechanisms in improving mitochondrial energy metabolism, scavenging excess reactive oxygen species (ROS), suppressing neuroinflammation, and regulating apoptosis. Additionally, this paper analyzes the design principles of various modification strategies-such as triphenylphosphine (TPP) modification, pH/ROS responsiveness, and drug-loaded nanozyme complexes-along with their efficacy validation in AD models. It further explores the future development trends of chitosan nanogel-mediated multi-target intervention and smart-responsive nasal-brain delivery systems, offering new directions for precision treatment of AD.","42426901":"ID: 42426901\nTitle: Emerging mechanisms and targeted therapy of PANoptosis in neurological diseases.\nAbstract: PANoptosis is a distinct inflammatory and lytic cell death pathway, orchestrated by the PANoptosome and executed through caspases and receptor-interacting protein kinases (RIPKs). Unlike other forms of programmed cell death, PANoptosis integrates components from multiple death signaling cascades. To date, several PANoptosome complexes - such as those nucleated by ZBP1, AIM2, RIPK1, and NLRP12 - have been characterized. These supramolecular assemblies form via domain-domain interactions upon detection of pathogen-associated or damage-associated signals. By eliminating infected and compromised cells, this coordinated pathway helps maintain tissue homeostasis, while its synchronized release of inflammatory cytokines and damage-associated molecular patterns (DAMPs) enhances innate immune responses, resulting in more effective pathogen clearance compared to any single cell death mechanism. Growing evidence underscores the relevance of PANoptosis across a spectrum of pathological conditions, including neurological disorders, infections, inflammatory diseases, cancer, and homeostatic imbalances, often mediated by PANoptosis-associated proteins. In neurological contexts - such as stroke, Parkinson's disease, Alzheimer's disease, and traumatic brain injury - PANoptosis activation correlates with disease progression and prognosis, highlighting its potential as a therapeutic target. In this review, we systematically outline the molecular foundations of PANoptosis, examine its role in neurological diseases, and summarize current pharmacological and methodological strategies for its modulation. A deeper understanding of PANoptosis may inform the identification of novel therapeutic targets for neurological disorders.","42427748":"ID: 42427748\nTitle: Early Loss of Deep Restorative Sleep and Auditory Stimulus Evoked 40-Hz activity of Hippocampal Parvalbumin Neurons in the APP/PS1 Mouse Model of Alzheimer's Disease.\nAbstract: Sleep abnormalities and dysfunction of gamma band (30-80 Hz) activity generated by parvalbumin (PV) interneurons are early characteristics of Alzheimer's disease (AD) which correlate with the severity of amyloid-β deposition (Aβ) and cognitive impairment. However, the timing of these alterations in vivo with respect to disease progression is unclear. Here, in longitudinal recordings from APP/PS1/PV-cre (AD mice) from 3-6 months, we found reduced sleep slow-wave power (0.5-4 Hz) in hippocampus and medial prefrontal cortex in AD mice as young as 3 months old, compared to non-AD (PV-cre) mice, well before overt pathology. This finding was primarily due to reductions in the NREM delta range (1.5-4 Hz), a hallmark of restorative functions of sleep. In contrast, beta (15-30 Hz) power linked to insomnia was significantly higher across all sleep-wake states. Loss of deep NREM sleep was not compensated by an increase in NREM sleep time, instead NREM sleep during the dark (active) phase was slightly but significantly lower in AD mice. 40-Hz auditory steady-state responses and associated evoked calcium responses of hippocampal PV neurons recorded using fiber photometry were also impaired by 3 months old. However, Y-maze performance in 3- and 6-month-old AD mice was not significantly different from non-AD mice. These results reveal reduced deep sleep and PV-associated 40-Hz activity as very early changes amenable to early intervention occurring prior to cognitive deficits. Furthermore, they establish APP/PS1 mice as a good model to causally test the relationship between sleep, PV neuronal activity and amyloid-mediated pathology.","42428045":"ID: 42428045\nTitle: Diagnosis of Alzheimer's disease from neuroimages using steerable quantum probabilistic hamiltonian generative modeling with adaptive chaotic satin bowerbird optimization.\nAbstract: Alzheimer's Disease (AD) is a disease of the brain that lowers quality of life due to cognitive impairment. A correct diagnosis is therefore essential for timely interventions and follow-up care for executives. However, existing deep learning methodologies for neuroimage-based diagnosis seriously lack reliability due to decreased accuracy and increased false positive rates, both of which can lead to misdiagnosis and suboptimal care planning. This study proposed an innovative Steerable Quantum Probabilistic Hamiltonian Generative Modeling with Adaptive Chaotic Satin Bowerbird Optimization (SQPHGM-ACSBO) framework for diagnosing AD using neuroimages within the ADNI dataset. A total of 5,154 neuroimages from the ADNI dataset were utilized in this study, comprising 2,590 MCI, 1,124 AD, and 1,440 cognitively normal (CN) samples. The process begins with image enhancement via an Adaptive Self-Guided Loop Filter, followed by precise brain region segmentation with GoogLeNet Inception-v3, and advanced feature extraction using a new Discrete Cosine-Krawtchouk-Tchebichef Transform (DCKTT). Classification is performed using the SQPHGM model, which combines the strengths of Steerable Transformers and Quantum-Probabilistic Hamiltonian Learning to model complex neuroimaging patterns, while the Adaptive Chaotic Satin Bowerbird Optimization (ACSBO) algorithm optimizes classification performance. With 99.9% accuracy and 99.8% precision, the suggested method outperforms current methods and provides a dependable, high-performance solution for AD diagnosis from neuroimaging data, according to experimental results. The main innovation of this work is the all-in-one optimization of steerable transformer-based directional feature learning, quantum-probabilistic Hamilton generator modeling, and adaptive-chaotic satin bowerbird optimization integrated within a single diagnostic pipeline, which allows for representing the complicated neuroimaging patterns better, and the convergence stability is also increased, compared to the previous deep learning-based Alzheimer diagnosis models.","42428048":"ID: 42428048\nTitle: Interpretable feature-transformer framework for cross-subject MCI detection using nonlinear dynamical and graph-theoretic EEG features.\nAbstract: Early and accurate detection of Mild Cognitive Impairment (MCI) is essential for preventing progression toward Alzheimer's disease (AD). In this cross-subject study, we investigate the effectiveness of entropy- and graph-based EEG features for distinguishing MCI from healthy controls (HC), using two modeling approaches: (1) a Transformer network applied to the engineered feature set, and (2) an EEGNet model trained on the same feature representation for comparison. The dataset consists of resting-state, eyes-closed EEG recordings from 183 participants (127 HC, 56 MCI), collected using a 20-channel STAT™ X24 wireless system and segmented into 3-second epochs. EEG data underwent standard preprocessing, including band-pass filtering, downsampling, normalization, and class-balancing augmentation applied to the minority class. From each channel, nonlinear dynamical measures (e.g., sample and fuzzy entropy, Higuchi fractal dimension, Lyapunov exponent) and graph-theoretic connectivity descriptors derived from coherence matrices across five frequency bands were extracted, yielding a structured 19[Formula: see text]77 feature representation. The feature-based Transformer achieved the best performance (97.04% ± 0.72), outperforming the feature-based EEGNet baseline and highlighting the benefits of combining rich handcrafted features with attention-based modeling. SHAP (SHapley Additive exPlanations) analysis provided global and local interpretability, revealing the most influential nonlinear and connectivity features as well as the EEG channels contributing most to classification. Overall, these results demonstrate the effectiveness of feature-Transformer integration and support the potential of interpretable feature-driven deep learning models for early MCI detection.","42429744":"ID: 42429744\nTitle: SMDNet: A Self-Training-Aware and Multi-Modal-Adaptive Deep Learning Network for Low-Data Aβ42 Probe Design and Optimization.\nAbstract: Amyloid-β (Aβ) plaque accumulation is a crucial hallmark of Alzheimer's disease, and fluorescence imaging can support disease diagnosis and monitoring. However, Aβ42 probe development is often hindered by trial-and-error experiments due to subtle structure-property effects. Here, we developed SMDNet, a self-training-aware and multimodal-adaptive deep learning (DL) framework for low-data Aβ42 probe design and optimization. SMDNet combines iterative self-training with confidence-aware and distribution-aware sampling to improve data quality, while integrating molecular graphs, fingerprints and protein descriptors through cross-attention and protein-conditional adaptive layer normalization. Ablation studies, external validation and generalization analyses confirmed the strong predictive ability of SMDNet. Interpretability analyses further highlighted chemically meaningful substructures associated with model predictions. As a proof of concept, SMDNet guided the rational design of five ThT-derived probe candidates, with TA3 showing favorable binding affinity and high-contrast imaging performance. Additional validation on coumarin- and naphthalimide-based candidates further supported useful predictive discrimination across distinct fluorescent scaffold classes.","42430077":"ID: 42430077\nTitle: Targeting IL-33 in Precision Neuroimmunology: Cellular Mechanisms and Therapeutic Strategies for CNS Disorders.\nAbstract: Interleukin-33 (IL-33), an alarmin cytokine of the IL-1 family, has emerged as a pivotal regulator of neuroimmune interactions in the central nervous system (CNS). Acting through its receptor ST2, IL-33 orchestrates diverse immune responses by modulating microglial polarization, shaping T cell differentiation, activating type 2 innate lymphoid cells (ILC2s), and engaging mast cell-macrophage regulatory circuits. Across distinct neurological disorders, including epilepsy, stroke, traumatic brain injury (TBI), Parkinson's disease (PD), Alzheimer's disease (AD), multiple sclerosis (MS), cerebral malaria, and glioma, IL-33 exerts both protective and pathogenic effects in a context-dependent manner. In epilepsy, IL-33 modulates neuroinflammation and neuronal excitability; in stroke, it attenuates acute neurovascular injury while influencing post-stroke remodeling; in AD, it enhances amyloid-β clearance and mitigates chronic neuroinflammation; in MS, it regulates autoimmune demyelination via T cell and innate immune pathways. These shared yet disease-specific mechanisms underscore IL-33's central role in neuroimmune homeostasis and its potential as a precision therapeutic target. Future research integrating multi-disease models, temporal disease staging, and single-cell multi-omics will be essential to define the conditions under which IL-33 modulation yields maximal therapeutic benefit.","42430835":"ID: 42430835\nTitle: Glymphatic dysfunction in neurodegeneration: From impaired clearance to mechanism-driven therapeutic innovation.\nAbstract: Glymphatic system refers to a system that involves perivascular clearance mechanisms within the brain, which are crucial for the elimination of neurotoxic proteins such as amyloid-β (Aβ) and tau proteins in Alzheimer's disease (AD), α-synuclein in Parkinson's disease (PD), and mutant huntingtin (mHTT) in Huntington's disease (HD). There is mounting evidence suggesting that glymphatic dysfunction is an important cause of neurodegenerative diseases, characterized by failure of cerebrospinal fluid-interstitial fluid (CSF-ISF) exchange due to abnormal clearance. Mechanistically, this dysfunction is affected by aging, astroglial aquaporin-4 (AQP4) depolarization, vascular impairment, sleep abnormalities, oxidative damage, and neuroinflammation. Additionally, aberrant glymphatic flow acts as a crucial link between peripheral and central pathologies, amplifying neurodegeneration via altered solute transport and inflammation signaling. Glymphatic dysfunction has been found to be involved in diseases such as AD, PD and HD, thus indicating the widespread significance of glymphatic pathology. Therapeutically, targeting glymphatic function through modulation of AQP4 polarization, improving sleep-dependent clearance, and decreasing oxidative and inflammatory mechanisms may provide promising strategy for disease modification. This review provides a comparative and mechanistic overview of glymphatic dysfunction across AD, PD, and HD, highlighting peripheral-central interactions, biomarkers, imaging approaches, and therapeutic strategies, while addressing unresolved issues related to transport mechanisms, causality versus epiphenomenon, and translational limitations.","42430964":"ID: 42430964\nTitle: Suboptimal adherence to brain health recommendations in patients pursuing anti-amyloid antibody therapy for Alzheimer's disease: Report from the Brain Health Vital Signs project.\nAbstract: Consensus is consolidating around a set of lifestyle and medical factors that can promote brain health and reduce the risk of dementia for older adults and further decline for those with early Alzheimer's disease (AD) and related disorders. Little is known about the degree to which recommended brain-healthy behaviors have been adopted by patients with early AD pursuing anti-amyloid antibody therapy (AAT), a proactive group interested in doing what is under their control to help preserve cognitive and functional status. Here, initial results of a clinically relevant quality improvement study are reported. To determine the extent to which patients pursuing AAT for AD adhere to consensus-based brain health recommendations. One hundred fifty patients with mild cognitive impairment (MCI) or mild dementia due to AD seeking AAT were studied and compared to a group of 117 patients with MCI or mild dementia who were not pursuing AAT. Using a clinical survey tool developed for the project, patients were assessed on 15 modifiable risk factors for cognitive decline and dementia, including 11 via e-survey (diet, physical activity, cognitive activity, sleep, social engagement, smoking status, alcohol consumption, hearing, vision, mood/stress, and purpose in life) and 4 via electronic medical record (EMR) (blood pressure, BMI, LDL cholesterol level, and HbA1c). For each factor, the percentage of each of the two patient groups that was not optimally adhering to brain health-related guidelines was calculated. For each individual, the total number of factors not optimally being followed was determined. Less than 3% of patients with early AD pursuing AAT were following or had anthropometric measures/lab values in line with all 15 brain health recommendations. The five factors with the lowest adherence rates involved physical activity, mood/stress, HbA1c, blood pressure, and BMI, with 44-63% of the AAT group suboptimally following consensus-based guidelines. For 11 of 15 factors, >25% of the group were not adhering to guidelines. No robust differences in degree or pattern of adherence to guidelines were observed between patients pursuing and not pursuing AAT. There were no data in the EMR for HbA1c in >42% of patients and for LDL in >23% of patients in either group. Suboptimal adherence to brain health recommendations may be common among patients with early AD, whether they are pursuing AAT or not. These results suggest that healthcare systems may need to develop more effective strategies and individualized interventions for addressing modifiable risk factors for cognitive decline and dementia, and more efficacious procedures for ensuring that relevant, actionable data associated with brain health are updated in the EMR.","42431913":"ID: 42431913\nTitle: Novel approach to early prediction of alzheimer's disease progression using integrated deep regulatory genetic neural network and optimized deep belief networks.\nAbstract: To enhance the prediction progression of Alzheimer's Disease is very excavating process. It is often very difficult to implement in the chronic neurodegenerative disease-related preprocessed gene expression data. Especially, Alzheimer's Disease (AD) prediction is a very crucial process in AD metadata diagnosis. Novelty: To explore this challenging prediction process in brain disease prediction, this research presents a proposed deep learning model, namely the Integrated Deep Regulatory Genetic Neural Network and Optimised Deep Belief Networks (IDRODN). This integration increases the affluence of prediction progression from genomic data. These prediction systems help identify early AD. This research utilizes the IDRODN, which can predict and confine each network's neurons and hidden layers against the benchmark dataset of Alzheimer's gene expression and uncertainty to predict Alzheimer's Disease. The comparative analysis on data from the Alzheimer's disease gene expression data Initiative database has achieved an accuracy of 98.3%. In addition, it has achieved a high F1 score of 0.986 for predicting different stages from Gene expression data. This shows the most accurate technique for predicting Alzheimer's Disease (AD) using the prognostic IDRODN model.","42431966":"ID: 42431966\nTitle: An interpretable multimodal framework using compact biomarkers and Kolmogorov-Arnold networks improves the early diagnosis of Alzheimer's disease.\nAbstract: Early diagnosis of Alzheimer's disease (AD), especially accurate identification at the mild cognitive impairment (MCI) stage, is crucial for slowing disease progression. Although deep learning has achieved promising performance in AD diagnosis, existing multimodal models often operate as \"black boxes,\" lacking the transparency required for clinical practice and failing to explicitly model deep interactions between imaging and clinical features. To address these limitations, this study proposes an interpretable multimodal framework, namely the Compact Biomarker Kolmogorov-Arnold Network (CBKAN). Specifically, we introduce EHCTNet with disease-specific attention to extract features from 3D MRI data, and innovatively constrain the encoder to output a set of compact biomarkers instead of traditional high-dimensional abstract vectors, mimicking the diagnostic logic of clinicians (e.g., judging brain atrophy). In addition, a hybrid feature Transformer is used to fuse these imaging biomarkers with clinical and genetic data, explicitly capturing complementary relationships across modalities. Finally, the Kolmogorov-Arnold Network (KAN) is adopted as the classifier to effectively model the highly nonlinear characteristics of AD progression. Experiments on 800 subjects from the ADNI dataset show that CBKAN achieves 91.1% accuracy and an F1-score of 0.910 in the AD/MCI/CN classification task, significantly outperforming existing mainstream methods. Statistical analyses validate the effectiveness of each component of the model. The proposed model provides a potentially interpretable and high-performing decision-support framework for early Alzheimer's disease diagnosis, although its cross-cohort generalizability and real-world clinical utility require further validation in independent external datasets.","42432263":"ID: 42432263\nTitle: Repurposing apremilast for alzheimer's disease: multitarget modulation of cAMP‑PI3K/Akt-GSK‑3β and NF‑κB signaling.\nAbstract: Alzheimer's disease (AD), the leading cause of dementia worldwide, represents a growing global health challenge driven by population aging, the absence of effective disease-modifying therapies, and its inherently multifactorial pathogenesis. This pathogenesis is characterized by amyloid-β (Aβ) aggregation, tau hyperphosphorylation, persistent neuroinflammation, oxidative stress, and synaptic dysfunction. Conventional single-target interventions have consistently failed against this complex interplay of molecular events, thereby highlighting the need for multitarget, systems pharmacology approaches capable of simultaneously modulating convergent pathways. Apremilast (APR), an FDA-approved, orally bioavailable phosphodiesterase-4 (PDE4) inhibitor, has recently emerged as a favorable drug repurposing candidate capable of elevating intracellular cAMP and triggering a cascade of neuroprotective mechanisms. Preclinical investigations from Aβ-challenged neuronal cultures to high-fat diet/streptozotocin-induced rodent models of AD demonstrate that APR attenuates Aβ-induced cytotoxicity, improves cognitive performance, and preserves neuronal and synaptic integrity. Mechanistically, APR mitigates NF-κB-mediated neuroinflammation through IκBα stabilization, thereby reducing the release of proinflammatory cytokines such as TNF-α and IL-6; activates the Nrf2/HO-1 antioxidant defense pathway, and, via cAMP-dependent PI3K/Akt signaling, inhibits GSK-3β to prevent tau hyperphosphorylation, synaptic loss, and neuronal degeneration. This review synthesizes current mechanistic evidence supporting apremilast as a potential multitarget repurposing candidate in AD, thereby addressing key knowledge gaps in the current literature. All supporting evidence was compiled from peer-reviewed sources indexed in PubMed, Web of Science, and Scopus. Guided by network pharmacology and systems biology frameworks, APR's polypharmacological profile positions it as a compelling multitarget candidate for advanced in vivo validation, human iPSC-derived neuronal studies, and AI-driven therapeutic discovery pipelines.","42432671":"ID: 42432671\nTitle: The role of AI-assisted drug repurposing in neurological disorders: a systematic review of validation strategies, challenges and opportunities.\nAbstract: Neurological disorders refer to a diverse group of conditions that affect the brain, peripheral nerves, and spinal cord and impair socioemotional, cognitive, motor, and sensory functions. Alzheimer's disease (AD), Multiple Sclerosis (MS), Parkinson's disease (PD), Huntington's disease (HD), and Amyotrophic Lateral Sclerosis (ALS) are some of the well-known neurodegenerative diseases that affect millions of people worldwide. Despite the advanced technologies and nano-drug delivery systems, the success rate of developing drugs for neurological disorders is significantly low. Among several constraints, including gastrointestinal irritation, rapid metabolism, and low stability, the blood-brain barrier (BBB) emerges as one of the key challenges in the development and application of drugs against neurological disorders. These challenges necessitate innovative approaches to develop cost-effective therapeutic strategies. Drug repurposing, the discovery of new therapeutic benefits of existing drugs, is a promising drug discovery approach for discovering potential treatment options for complex neurological disorders. This review aims to explore the advanced and significant progress in drug repurposing for major neurological disorders, including MS, AD, PD, ALS, HD, stroke, and neuropsychiatric conditions. It places an explicit emphasis on discussing the potential role of artificial intelligence (AI)-assisted drug repurposing and understanding of the biological mechanisms in discovering new drugs for these neurological conditions. This also examines current challenges in drug repurposing and provides a critical review of the available opportunities and limitations in AI-assisted drug repurposing.","42432729":"ID: 42432729\nTitle: Reshaping the immune landscape: next-generation microglia-targeted therapies for Alzheimer's disease.\nAbstract: Alzheimer's disease (AD) is a significant global health challenge characterized as a multifactorial neurodegenerative disorder, involving amyloid-β (Aβ) and Tau aggregation, neuroinflammation and progressive neuronal injury. While Amyloid-targeted therapies have achieved a breakthrough in prevention of Aβ aggregation, the strategies face notable limitations in achieving curative outcomes and management of amyloid-independent central nervous system (CNS) dysfunction. Consequently, targeting microglia, the central immune cells of the brain, has emerged as a promising strategy to enhance the specificity and efficacy of AD interventions. Accumulating evidence indicates microglial dysfunction is not a passive immune bystander of AD, but serves as a critical mechanistic nexus linking Aβ accumulation and AD symptomatic phenotype. This review critically examines the \"next generation\" of microglial therapeutics, moving beyond broad immunosuppression to precision phenotype modulation. We highlight breakthrough strategies in recent years including immune reconstitution, metabolic reprogramming, nanomaterial-mediated drug delivery, and the revolutionary potential of iPSC-derived microglia replacement. By elucidating the rationale underlying the specific strategies based on microglial biofunction and potential molecular mechanism in AD pathology, we provide an overview of current development of clinical trials and cutting-edge modalities aimed at restoring microglial homeostasis, affording an opportunity to alter the AD trajectory. This review aims to delineate the path from bench to bedside and propose promising pathways to overcome current bottlenecks in AD drug development.","42434351":"ID: 42434351\nTitle: Region-specific Transcriptomic Signatures in Alzheimer's Disease: A Meta-analysis of Vulnerable Brain Regions Reveals MicroRNA-hub Gene Regulatory Networks.\nAbstract: Alzheimer's disease (AD) is characterized by progressive neurodegeneration in regionally vulnerable brain areas, yet molecular insights into early pathogenic mechanisms remain limited. We conducted a meta-analysis of transcriptomic datasets from brain regions affected in early-to-moderate AD - including entorhinal cortex, CA1 hippocampus, angular gyrus, and frontal cortex synaptoneurosomes - using data from seven mRNA and one microRNA (miRNA) microarray studies (GSE16759, GSE110226, GSE37264, GSE26972, GSE36980, GSE37263, GSE39420, and GSE157239). Preprocessing included background correction, log2 transformation, quantile normalization, and batch correction via ComBat. Differentially expressed features were defined as false discovery rate <0.05 and | logFC| ≥ 1.23 (genes) or ≥ 2 (miRNAs). We identified 172 differentially expressed genes (122 upregulated and 50 downregulated) and 82 significant miRNAs. Hub genes included Inositol-trisphosphate 3-kinase B (ITPKB), Synaptotagmin 1, Dystrobrevin alpha (DTNA), X Inactive Specific Transcript, and Regulator of G protein signaling 4 (RGS4). Functional enrichment highlighted calcium signaling, synaptic failure, and neuroinflammation. Notably, hsa-miR-30d-5p was predicted to target both ITPKB and DTNA, suggesting a regulatory axis linking miRNA dysregulation to calcium dyshomeostasis. Receiver operating characteristic analysis revealed that only RGS4 showed moderate discriminative capacity (area under the curve [AUC] =0.70), while other hub genes (e.g., ITPKB, AUC = 0.40) exhibited below-chance performance, underscoring the limitations of single-gene classifiers in postmortem tissue. This study provides mechanistic hypotheses - rather than diagnostic biomarkers - by uncovering region-specific, miRNA-mediated regulatory networks in AD-affected brain tissues. Future validation in accessible biofluids is essential before clinical translation.","42434375":"ID: 42434375\nTitle: A real-world feasibility study: at home longitudinal use of the Cumulus NeuLogiq® platform for electrophysiological and neurocognitive measures in patients with mild Alzheimer's Disease dementia.\nAbstract: Dementias, including those caused by Alzheimer's Disease (AD), are a leading global cause of death, necessitating improvements in early detection and development of more effective disease-modifying therapies. Well-validated pen-and-paper measures serve as the primary method used for cognitive assessment in research and clinical trials in AD. However, these suffer from rater error, infrequent \"snapshot\" bias, and have limited sensitivity to early-stage pathology, which presents challenges for measuring efficacy in prevention trials. Recent technological advances offer the potential to measure subtle cognitive changes and account for day-to-day variability through real-world data collection. The Cumulus Neuroscience NeuLogiq® platform (\"the platform\"), is comprised of a wireless electroencephalography (EEG) headset, tablet-based cognitive tasks based on well-established paradigms which were designed to be user-friendly based on patient panel inputs, third party integrations (mood, speech and sleep assessments) and cloud-based analytics. This platform has demonstrated utility in healthy populations and may enable objective, frequent, and patient-centered disease tracking in AD and other CNS disorders. This paper presents findings from a 52-week study involving individuals with mild AD dementia and healthy controls. Analyses focus on usability (e.g., ease of use ratings and reported technical issues) and feasibility (e.g., adherence; withdrawal rates) of using the platform, unsupervised, in the real-world at home setting and exploring how baseline cognitive status and demographic factors impact platform usability. Longitudinal study data after 12 months offer valuable insights into the feasibility of the platform for patients with mild AD enrolled in long-term studies, such as clinical trials. The participants' high adherence to the protocol underscores the practicality of utilizing the platform in this context. Although participants with dementia reported lower confidence levels (31.6%, N = 18) and encountered some minor technical challenges during the initial home setup (accounting for 16.1% of issues reported in Stage 1), they nonetheless demonstrated strong engagement, achieving an overall adherence rate of 77% across the 52-week study protocol. This demonstrates that even participants with dementia remain able and willing to use the EEG headset and complete tablet-based cognitive tasks over a year, from the comfort of their homes.","42434591":"ID: 42434591\nTitle: Mechanisms and disease associations of oxidative stress-mediated brain-bone axis dysregulation: a knowledge mapping and trend analysis based on Bibliometrics.\nAbstract: Oxidative stress, characterized by the systemic imbalance between reactive oxygen species and antioxidant defenses, is increasingly recognized as a central pathological nexus driving the dysregulation of the brain-bone axis. Despite the accumulation of empirical evidence, a systematic characterization of the field's intellectual structure and thematic progression remains absent. This study employs a multi-database bibliometric approach to map the research landscape of oxidative stress-mediated neuro-skeletal crosstalk and identify emerging research frontiers. A systematic search was performed across the Web of Science Core Collection, Scopus, and PubMed databases from their inception to April 30, 2025. Following a rigorous screening process based on predefined criteria, 717 relevant publications were included. Bibliometric mapping and network analyses were conducted using CiteSpace, VOSviewer, and the Bibliometrix R-package to evaluate collaboration patterns, co-citation structures, and keyword evolution. The analysis reveals a steady increase in research output since 2009, marked by distinct developmental phases. Early investigations primarily focused on fundamental oxidative damage mechanisms, while subsequent research transitioned toward systemic disease associations (e.g., Alzheimer's disease and osteoporosis) and targeted intervention strategies, including mesenchymal stem cell therapy and melatonin. Recent trends indicate a methodological and thematic shift toward high-resolution translational themes, such as neuroimmune regulation and the \"gut-brain-bone\" axis. Notably, \"gut microbiota\" and \"extracellular vesicles\" have emerged as high-centrality nodes, reflecting an increasing focus on inter-organ communication and systemic redox modulation. This study provides the first comprehensive mapping of the research trajectories within the oxidative stress-mediated brain-bone axis field. The findings delineate a clear progression from isolated mechanistic studies toward integrated, multi-system frameworks, underscoring the shift toward precision medicine and translational applications. By identifying current research gaps and emerging hotspots, this analysis offers a systematic reference for future interdisciplinary investigations and the development of targeted therapeutic strategies for neuro-skeletal comorbidities.","42434808":"ID: 42434808\nTitle: Brain targeting and trafficking of extracellular vesicles in central nervous system diseases: a therapeutic roadmap.\nAbstract: Extracellular vesicles (EVs) mediate intercellular signaling in the central nervous system (CNS) by transferring lipids, proteins, and nucleic acids among neurons, glia, endothelium, and immune cells. Brain targeting depends on a linked sequence: EV ligands and adsorbed protein coronas engage receptor modules, select endocytic routes, determine intracellular fate, and define the therapeutic readouts. These fates include lysosomal degradation, recycling, rare cytosolic delivery, or transport across the blood-brain barrier (BBB). In disease, the same pathways can disseminate proteopathic seeds and amplify neuroinflammation. Heparan sulfate proteoglycans (HSPGs) and LDL receptor family members, including low-density lipoprotein receptor-related protein 1 (LRP1), regulate tau, α-synuclein, and amyloid-β handling. Phosphatidylserine readers and complement shape myeloid sink capture and inflammatory output. Integrin, tetraspanin, and ICAM-1 nanoclusters influence avidity, organotropism, and immune suppression. At the BBB, endothelial HSPGs, LRP1, and transferrin receptor (TfR) support receptor-mediated uptake, motivating engineered ligands such as rabies virus glycoprotein-derived peptides, Angiopep-2, and TfR binders. However, endosomal escape remains a major kinetic barrier to nucleic acid delivery. We synthesize these principles across Alzheimer's disease, Parkinson's disease, amyotrophic lateral sclerosis, glioblastoma, and demyelinating disease, and outline design and assay standards needed to translate EV biology into safe, manufacturable CNS therapeutics.","42434900":"ID: 42434900\nTitle: Amyloid-related imaging abnormalities after immunotherapy: How might brain microvascular basement membrane components be involved?\nAbstract: Basement membrane components are integral to the physiologic function of cerebral microvessels. Immunotherapy (including by the use of lecanemab) in Alzheimer's disease patients may result in vascular complications identified by neuroimaging (ARIA-E and ARIA-H). This pilot study (on a relatively small number of human brain specimens) suggests one mechanism might be through the effects of lecanemab on a collagen component of said microvessel walls. It utilizes microvessels isolated from human brains (of Alzheimer's disease patients) and maintained in a viable state, to examine this mechanism using novel biochemical and molecular approaches. These yield preliminary evidence of how lecanemab may influence a specific component of the cerebral microvasculature and suggest other studies that may be used to address this important question.","42434915":"ID: 42434915\nTitle: Low body mass index is associated with higher rates of mild cognitive impairment and worse memory performance among older Canadian adults: An analysis of the Canadian Longitudinal Study on Aging (CLSA) database.\nAbstract: BackgroundBoth low and high body mass index (BMI) have been identified as risk factors for dementia, though the association between the range of BMI classifications and presence of mild cognitive impairment (MCI) and memory performance warrants further investigation.ObjectiveThis study aimed to investigate the association between the range of BMI classifications and presence of MCI, as well as overall memory performance, among a large Canadian sample of older adults.MethodsThis study utilized data from 40,232 participants from the Canadian Longitudinal Study on Aging (CLSA). The association between BMI and cognitive function was examined at baseline and first follow-up (3 years). Linear regression was used to model the relationship between BMI and memory performance, while logistic regression was used to assess the association between BMI and the odds of meeting criteria for MCI.ResultsIn the final regression model, a weak (partial eta-squared=0.8%, 95% CI [0.63%, 0.97%]) inverted-U relationship between BMI and REYII memory performance was demonstrated, with normal BMI showing the best performance. In the final logistic regression model, being underweight was associated with 3.22 times greater odds (95% CI [1.63, 6.39]) of meeting criteria for MCI compared to normal BMI. No association was demonstrated between change in BMI and change in cognitive performance between baseline and 3-year follow-up.ConclusionsBeing underweight is linked to higher odds of MCI, suggesting the importance of adequate nutrition in preserving cognitive health among older adults.","42435043":"ID: 42435043\nTitle: Exploring thiazole conjugates as cholinesterase inhibitors for Alzheimer's disease treatment.\nAbstract: Alzheimer's Disease (AD), a major global health concern, is marked by memory loss and cognitive decline, especially in the elderly. Cholinergic hypothesis is one of the leading hypotheses toward the treatment of AD, prompting the development of cholinesterase (ChE) inhibitors. Acetylcholinesterase (AChE) remains a vital therapeutic target due to its role in enhancing acetylcholine levels and neural function. The natural products, synthetic analogs, and hybrid molecules have been evaluated as inhibitors of ChEs. Recent studies highlight thiazole-fused heterocyclic scaffolds and their derivatives as promising ChE inhibitors with neuroprotective potential. This article covers the synthesis of conjugates of thiazole with piperazine, benzimidazole, pyrazole, and other heterocyclic compounds, along with their potential as ChE inhibitors.

Advances in biomarker development, molecular staging, and precision medicine are reshaping therapeutic strategies and clinical trial design across Parkinson's disease, Alzheimer's disease, frontotemporal dementia, amyotrophic lateral sclerosis, Huntington's disease, and related disorders. This review summarizes emerging therapeutic approaches, including monoclonal antibodies targeting protein aggregation, immune-modulating and metabolic interventions, antisense oligonucleotides, gene replacement and genome-editing strategies, stem cell-based therapies, and neurosurgical delivery platforms and neuromodulation technologies. It also examines evolving clinical trial methodologies such as biomarker-enriched recruitment, adaptive and delayed-start designs, platform trials, decentralized models, and master protocols. Additional emphasis is placed on diagnostic biomarkers, multimodal artificial-intelligence pipelines, systems-biology perspectives, network-based therapeutic strategies, and the reproducibility and interpretability requirements for computational tools. Despite recent progress, major challenges remain, including biological heterogeneity, limited translatability of preclinical models, delivery barriers, long-term safety concerns, and inequities in access to biomarker-based care and trial participation. Future directions will require combination therapies, integrated biomarker pipelines, preventive strategies, and pragmatic trial systems capable of translating biological advances into durable and equitable clinical benefit.","42435703":"ID: 42435703\nTitle: Rationally designed phytochemical-derived carbamate hybrids unveiling potent inhibition of cholinesterase and amyloid-β peptides.\nAbstract: Alzheimer's disease (AD) is most likely to be caused by the accumulation of Aβ and dysfunction of the cholinergic pathology. Oxidative damage, alterations of brain glucose metabolism, and cognitive impairment are all demonstrated in the STZ models. In order to overcome such effects, a new set of phenolic-carbamate conjugates (5a-5h) was synthesized, and their structures were elucidated using FTIR, UV, and NMR spectroscopy. The in silico studies confirmed excellent binding capabilities against AChE and Aβ targets. In vitro antioxidant assays depicted a significant free radical scavenging ability, with compound 5c exhibiting the enhanced effect. Cell line study with SH-SY5Y and PC12 cells showed greater % cell viability. AChE activity demonstrated compound 5c has significant effectiveness (IC50 = 1.98 uM). Neurobehavioral activity showed an improvement in learning and memory during behavioural assessments. In vivo antioxidant study showed greater scavenging activity (SOD, CAT, GSH), reduced of oxidative stress (MDA, NO), and the improvement in total antioxidant activity. Overall, the compound 5c has demonstrated significant results comprising decreased cholinesterase and Aβ inhibition deciphering enhanced cholinergic restoration. Hippocampal integrity was preserved, as it was confirmed by histopathological examination. It concludes that bromo-vanillyl carbamate derivative 5c (30 mg/kg) has potent antioxidant, anti-amyloid, and neuroprotective characteristics, rendering it a promising multitarget lead that warrants further investigation for the treatment of AD.","42435764":"ID: 42435764\nTitle: Neuron-Targeted Exosomal Delivery of siRNA Against RIPK3 Slows Neurodegenerative Progression in Alzheimer's Disease.\nAbstract: A major challenge in RNA therapeutics for central nervous system disorders is the lack of delivery systems capable of crossing the blood-brain barrier (BBB) while achieving cell-type-specific targeting. Herein, we develop an engineered exosomal siRNA delivery platform for systemic, neuron-targeted RNA transport to the brain. The platform leverages exosomes derived from an immortalized mouse hippocampal neuronal cell line as a biomimetic and functionally privileged material source, enhancing neuronal uptake and intracellular delivery efficiency. Through surface functionalization with a rabies virus glycoprotein-derived peptide, the system enables receptor-mediated BBB transcytosis and programmable siRNA loading. In human cortical organoids, the platform achieves efficient cytosolic delivery and robust gene silencing in neurons, demonstrating high delivery precision and bioavailability. As a proof of concept, targeting receptor-interacting protein kinase 3 (RIPK3) modulates necroptosis, a key pathway in inflammatory neurodegeneration. In transgenic mouse models, systemic administration suppresses RIPK3/MLKL signaling, reduces neuronal loss, and alleviates neuroinflammation and tau-associated pathology. Transcriptomic analyses further indicate stabilization of neuronal homeostasis across vulnerable brain regions. Collectively, the study establishes a modular and programmable exosomal RNA delivery platform and highlights age-defined, cell-derived biomaterials as a generalizable strategy for overcoming delivery barriers in neurological diseases.","42435857":"ID: 42435857\nTitle: Cellular Basis of Medium Flow-Mediated Reduction of Aβ Neurotoxicity in Cultured Neurons.\nAbstract: Alzheimer's disease (AD) is a neurodegenerative disorder characterized by elevated concentrations of amyloid β1-42 (Aβ1-42) in the brain, where it exerts neurotoxic effects. A recent study demonstrated that medium flow at approximately 10 μm/s reduces Aβ1-42 neurotoxicity in explant brain cultures containing neurons and beating ependymal cilia; however, the underlying mechanisms remain unclear. Neurons migrating from the explant and located within 300 μm of the beating cilia were exposed to cilia-generated medium flow, allowing analysis of Aβ1-42 toxicity under fluid flow conditions. Aβ1-42-containing putative EV-related extracellular particles (putative EV-related Eps), with diameters of 100-400nm were detected in the culture medium and exhibited neurotoxic effects. Pharmacological inhibition of EV release and endocytosis reduced intracellular accumulation of Aβ1-42 and attenuated neuronal toxicity. Under medium flow, fewer putative EV-related EPs bound to neurons, and their binding duration was significantly shortened. Rhodamine-conjugated concanavalin A staining revealed enhanced cell-surface glycan labeling in damaged neurons on the non-ciliated side compared with neurons on the ciliated side. These results suggest that shear stress reduces neuronal accumulation of Aβ1-42-containing putative EV-related EPs, likely through modulation of cell-surface glycosylation composition.","42435996":"ID: 42435996\nTitle: Targeting the APOE4-driven peripheral-central immune axis: A new frontier for Alzheimer's disease therapy.\nAbstract: Alzheimer's disease (AD) is a progressive neurodegenerative disorder and a growing global health challenge. Despite decades of research dominated by the amyloid cascade hypothesis, single-target therapies aimed at Aβ or tau have largely failed, underscoring the need for a broader framework. Emerging evidence implicates neuroimmune dysfunction as a central driver of AD pathology, with the \"peripheral-central immune axis\" emerging as a critical node. The APOE4 allele, the strongest genetic risk factor for sporadic AD, plays a pivotal role in both central nervous system (CNS) lipid metabolism and peripheral immune homeostasis. This review synthesizes the association between APOE4 and peripheral immune dysregulation and its impact on neurodegeneration. We discuss APOE expression in CNS and peripheral immune cells, highlighting APOE4-associated alterations in monocyte/macrophage polarization, T cell subsets via IL-7/IL-7R downregulation, and gut microbiota composition. We delineate mechanisms by which APOE4 is associated with blood-brain barrier compromise, may promote conditions for immune cell trafficking, and contributes to neuroinflammation. Integrating preclinical and clinical evidence, we propose an \"APOE4-associated peripheral-central immune infiltration cascade\" as a unifying framework for understanding systemic AD pathogenesis. Finally, we review emerging therapeutic strategies targeting peripheral immunity and APOE, discussing multi-target approaches guided by APOE genotype and immune biomarkers, shifting from a CNS-centric toward a systemic immunomodulatory paradigm for precision medicine.","42436002":"ID: 42436002\nTitle: CAPNS1 restoration partially alleviates mitochondrial dysfunction and synaptic deficits in Alzheimer's disease through the Ca2⁺-CaMKIIβ-MAPK-PGC-1α axis.\nAbstract: Alzheimer's disease (AD), a progressive neurodegenerative disorder characterized by brain atrophy and cognitive decline. While the amyloid cascade hypothesis remains the dominant framework, accumulating evidence indicates that mitochondrial dysfunction critically contributes to AD progression. Although improving mitochondrial function has been shown to rescue cognitive deficits in AD models, the underlying molecular mechanisms remain elusive. In this study, we identified a significant reduction in calpain small subunit 1 (CAPNS1) expression in both AD patient samples and male transgenic mouse models. Decreased CAPNS1 levels were strongly correlated with mitochondrial ultrastructural damage, reduced mitochondrial DNA (mtDNA) copy number, and progressive synaptic loss. Mechanistically, we found that CAPNS1 positively regulated mtDNA transcription and mitochondrial gene expression, and pharmacological data suggested the involvement of the Ca2⁺-CaMKIIβ-MAPK-PGC-1α signaling axis, a master pathway governing mitochondrial biogenesis and respiratory capacity. This activation subsequently restored cellular ATP production and reduced mitochondrial reactive oxygen species accumulation. Importantly, neuronal-specific CAPNS1 upregulation in APP/PS1 transgenic mice markedly improved mitochondrial cristae integrity, reversed hippocampal long-term potentiation deficits, increased dendritic spine density, and partially alleviated spatial memory deficits in behavioral tests. We noted that loss-of-function experiments (e.g., CAPNS1 knockdown or knockout) were not performed in this study, and the proposed Ca2⁺-CaMKIIβ-MAPK-PGC-1α axis should therefore be interpreted as a suggestive working model requiring further validation. Collectively, our findings indicate that CAPNS1 serves as a key regulator of mitochondrial function. By linking Ca2⁺ signaling to mitochondrial gene expression and synaptic integrity, CAPNS1 represents a promising therapeutic target for ameliorating synaptic loss and cognitive decline in AD.","42437010":"ID: 42437010\nTitle: Relation between voxel-based specific regional analysis system for Alzheimer's disease (VSRAD) on 3-tesla MRI and cognitive performances: Practical application in clinical settings.\nAbstract: Voxel-based specific regional analysis system for Alzheimer's disease (VSRAD) software using MRI scanner allows quantification of hippocampal and parahippocampal atrophy in the medial temporal structures by Z-score, and this score is widely used in clinical Alzheimer's disease (AD) diagnosis. However, it is unclear whether the Z-score is useful to discriminate normal aging from cognitive impairment (CI) or mild cognitive impairment (MCI). The present study examined the associations between VSRAD Z-score and cognitive performance quantified by Memory Performance Index (MPI) and determined a Z-score cut-off value. Three-tesla brain MRI was conducted in 100 outpatients without dementia, and all MRI data were analyzed using VSRAD. The target region of interest (ROI) mainly consisted of the para hippocampal gyrus. The degree of atrophy in the ROI was obtained from the averaged positive Z-score of the ROI. Cognitive performance was evaluated with the Japanese version of the MCI screen (MCIS). Patients were classified into normal (NL) and below normal (BNL) cognitive groups by MPI. The relation between MPI and VSRAD Z-score were assessed with logistic regression analysis, and the cut-off value for Z-score was determined by receiver operating characteristic curve analysis. Sixty-two percent (62%) were identified as the BNL group by MPI. Univariate analyses found that the BNL group had a significantly higher age, shorter years of education, and higher Z-score in VSRAD compared to the NL group, but no statistically significant difference was observed between genders. Bivariate correlation found that MPI, which is adjusted for age, gender, and years of education, was significantly correlated with Z-score assessed by VSRAD (Pearson's r = -0.52, p < .001). A subsequent logistic regression of VSRAD Z-score on BNL classification was used to generate a receiver operating characteristic curve (AUC = 0.75). The Youden index was applied to identify a cut-off value of VSRAD Z-score of 1.14 (sensitivity = 62.9%; specificity = 84.2%) to classify MPI < 50.2 (BNL) with overall accuracy of 73.5%. VSRAD Z-score using VSRAD software was one independent factor significantly associated with cognitive performance measured by MPI.

Cross-sectional analysis of 2024 data from the National Dementia Workforce Study, a nationally representative survey of primary care providers (PCPs) who treat Medicare beneficiaries with dementia. We used survey weights to generate nationally representative estimates of self-reported biomarker use. Among 2574 PCPs, computed tomography/magnetic resonance imaging (CT/MRI) (79%) and neuropsychological testing (71%) were most commonly used, followed by positron emission tomography (PET) (18%), plasma (16%), genetic (14%), and CSF testing (9%). PCPs confident in diagnosing dementia and from specialist settings were more likely to report ordering PET, plasma, genetic, and CSF testing. This study describes patterns in the adoption of AD biomarkers in the year after Medicare expanded coverage for some biomarkers, providing a baseline for measuring changes in biomarker use.

Its defining pathologies are hyperphosphorylated tau tangles and amyloid beta (Aβ) plaques. We analyzed the proteomes of 115 post mortem temporal lobe samples by mass spectrometry and searched with a dedicated AD spectral library including tau post‑translational modifications and Aβ isoforms to examine global protein changes in LOAD and EOAD. AD tissues showed mitochondrial and synaptic pathway downregulation and immune and small‑molecule metabolic process upregulation, with EOAD exhibiting larger fold changes. AD biomarkers were elevated, and two multi‑phosphorylated tau peptides (p‑tau231/p-tau235 and p-tau231/p-tau235/p-tau237) were detected predominantly in AD. Aβ was present in 45% of cognitively unimpaired elderly controls, with subtle proteome changes resembling an early stage of neurodegeneration. EOAD appears more aggressive. Tau p-tau231/p-tau235 and p-tau231/p-tau235/p-tau237 hold promise as novel AD biomarkers. Aβ's detection in cognitively unimpaired elderly controls precedes clinical AD symptoms.","42438861":"ID: 42438861\nTitle: Antidepressant use and dementia, cognitive measures, and neuroimaging outcomes: A population-based cohort study.\nAbstract: Prior observational studies have reported conflicting results regarding whether antidepressant treatment reduces long-term dementia risk, likely due to confounding by indication and reverse causation. We aimed to investigate the association between baseline antidepressant use and incident dementia, incorporating cognitive and neuroimaging outcomes. We conducted a prospective cohort study using UK Biobank participants free of dementia at baseline. Antidepressant use was self-reported at baseline (2006-2010). Incident dementia was identified through linked electronic health records until December 19, 2022. Cox proportional hazards models estimated hazard ratios (HRs) for all-cause dementia, Alzheimer's disease (AD), and vascular dementia (VD), adjusting for sociodemographic, lifestyle, health-related, antidepressant indication factors, and co-medication of other anticholinergics. In subsamples, cognitive performance (n = 57,330) and structural brain imaging (n = 42,276) were examined as intermediate outcomes. Among 461,464 participants, 33,721 (7.3%) reported baseline antidepressant use. Over a mean follow-up of 13.4 years, 7,922 (1.7%) developed incident dementia. Baseline antidepressant use was associated with higher risks of all-cause dementia (adjusted HR: 1.47, 95% CI 1.36-1.60), AD (1.53, 1.36-1.73), and VD (1.44, 1.23-1.70). Users performed worse on fluid intelligence and prospective memory tasks and showed lower total and gray matter volume, regional reductions in the hippocampal gray matter and basal nucleus, and greater white matter hyperintensity volume. Baseline antidepressant use was linked to a higher risk of dementia, poorer cognitive performance, and adverse brain structural changes. These findings underscore the importance of judicious prescribing, regular cognitive monitoring, and consideration of non-pharmacological approaches in clinical care.","42439047":"ID: 42439047\nTitle: The social environment and cognitive aging over the life course: laying out critical concepts and research gaps.\nAbstract: The social environment refers to our interpersonal relations, workplaces, and neighborhoods, towns, or cities in which we live.

Still, relatively little is known about how social-environmental exposures affect cognitive function over the life course and into older ages. Addressing this limitation, our paper outlines key features of the social environment and recommends priority areas of research on the social environment and cognitive aging. We divide our discussion into three subdomains: social connections, residential context, and work context. We then identify important gaps in the conceptual and empirical literature before outlining avenues for future research to strengthen our understanding of how social-environmental exposures over the life course link with cognitive function and AD/ADRD risk in late life.","42439628":"ID: 42439628\nTitle: Lymphoid-like Suppressive Microglia in Alzheimer's Disease: A New Neuroimmune Regulatory Axis?\nAbstract: Microglia are central regulators of Alzheimer's disease pathogenesis, but their roles cannot be reduced to a simple protective-versus-harmful dichotomy. Genetic, single-cell, and spatial studies have shown that Alzheimer 's-associated microglia occupy diverse disease-linked states shaped by amyloid plaques, tau pathology, lipid stress, complement activation, astrocyte signaling, aging, and immune genetic risk. Among the regulatory nodes controlling these states, SPI1, which encodes the myeloid transcription factor PU.1, has emerged as a key determinant of microglial identity and disease responsiveness. Human genetic studies suggest that reduced SPI1 expression may be protective, whereas experimental data indicate that excessive PU.1 suppression can impair essential microglial functions. This review examines the emerging concept that partial, plaque-associated reduction in PU.1 may enable a distinct lymphoid-like immunoregulatory microglial program marked by CD28 expression. Recent evidence suggests that PU.1-low CD28-positive microglia may restrain neuroinflammation and amyloid pathology, raising the possibility that Alzheimer's plaques induce not only inflammatory and phagocytic microglial responses, but also endogenous suppressive programs that limit tissue damage. We discuss this proposed PU.1/CD28 regulatory axis in relation to disease-associated microglia, TREM2-APOE signaling, complement-mediated synapse loss, antigen-presentation pathways, plaque-niche biology, and therapeutic microglial reprogramming. We also highlight major unresolved questions, including whether PU.1-low CD28-positive microglia are present and functional in human Alzheimer's disease, whether they are specific to amyloid-rich niches or extend to tau and mixed pathologies, and how such states could be safely manipulated without disrupting essential immune surveillance. We propose that lymphoid-like suppressive microglia represent a promising but still unproven framework for understanding protective neuroimmune regulation in Alzheimer's disease and for developing state-specific microglial therapies.","42439636":"ID: 42439636\nTitle: Human Microglial Molecular Alterations in Aging and Alzheimer's Disease.\nAbstract: Microglia, the resident innate immune cells of the central nervous system, are central players in brain development, healthy aging, and degenerative pathology, including Alzheimer's disease (AD). Aging is a major risk factor for AD, and various studies have identified alterations in microglial molecular signatures and morphological patterns that overlap with microglial states during aging. However, the mechanisms underlying the divergence of aging trajectories toward disease remain unclear. Thus, understanding the molecular changes in microglia during aging and AD pathology is crucial to elucidating the mechanisms that drive disease progression. In this review, we examine current advances in understanding the phenotypic alterations in human microglia, highlighting gene signatures and morphological changes that may aid in defining microglia's molecular and functional programs in healthy aging and over the course of AD. We further explore the roles of oxidative stress and cellular senescence in driving the development of a chronic reactive state in microglia during aging, which may also contribute to the complex process underlying the onset and progression of AD pathology. This review highlights the advancements in therapeutic strategies focused on targeting pertinent pathological microglial changes during aging and in disease to mitigate the AD neurodegenerative process.","42439654":"ID: 42439654\nTitle: Emerging New Pathways in Malignant Neoplasms and Neurodegenerative Disorders: Perspectives for Therapeutics.\nAbstract: Neurodegenerative disorders such as Alzheimer's disease (AD) and malignant neoplasms are among the most prevalent age-associated diseases worldwide. Although cancer is characterized by uncontrolled proliferation, resistance to apoptosis, and metabolic reprogramming, AD and other neurodegenerative disorders such as Lewy body disease (LBD) including Parkinson's Disease (PD) and fronto-temporal lobar degeneration (FTLD) are defined by synaptic dysfunction, neuronal loss, neuroinflammation, and impaired proteostasis with misfolded protein aggregates. Despite these contrasting phenotypes, converging epidemiological and molecular data support an inverse relationship between cancer and neurodegenerative disorders, whereby a history of cancer is associated with reduced AD risk, whereas AD is linked to a lower incidence of multiple malignancies. These observations suggest that oncogenesis and neurodegeneration may represent divergent outcomes of shared biological processes dysregulated during aging. This conundrum likely reflects differential regulation of core cellular pathways governing cell survival, stress responses, metabolism, and genomic integrity but could also reflect the differential influence of aging pathways and secreted growth factors. Pro-survival and proliferative signaling pathways commonly activated in cancer, including PI3K-AKT-mTOR signaling, altered p53 function, enhanced DNA damage tolerance, and anabolic metabolism, are often impaired in AD, LBD and FTLD, where neurons exhibit heightened vulnerability to stress, mitochondrial dysfunction, defective autophagy, and activation of pro-apoptotic cascades. Conversely, tumor-suppressive mechanisms that restrain proliferation may protect against malignancy but increase susceptibility to degeneration in post-mitotic neurons. Aging-related processes such as cellular senescence, immune dysregulation, and loss of proteostasis may further exert divergent effects in oncogenesis and neurodegeneration. This review aims to clarify associations between specific cancer types and neurodegenerative disorders, examine shared and opposing selected molecular mechanisms linking specific cancers and neurodegeneration, and contextualize these relationships within broader aging pathways (e.g., cell senescence, proteostasis). By integrating epidemiological, mechanistic, and therapeutic perspectives, we highlight unifying biological principles and translational opportunities at the intersection of cancer, neurodegeneration, and aging.","42439681":"ID: 42439681\nTitle: Rethinking Anti-Inflammatory Therapy in Alzheimer's Disease: From Broad Suppression to Stage-State-Space Neuroimmune Reprogramming.\nAbstract: Alzheimer's Disease (AD) is now understood as a biologically diverse condition, with amyloid and tau pathology evolving within dynamic neuroimmune networks. This challenges the traditional view that AD-related inflammation can be broadly suppressed therapeutically. We review evidence showing that neuroinflammation in AD is stage-dependent, cell-state-specific, spatially organized, and functionally complex. Microglia and astrocytes can aid in plaque containment, debris clearance, synaptic balance, metabolic adaptation, and tissue repair, but may also exacerbate injury through type-I interferon, inflammasome, complement, tumor necrosis factor, and lipid pathways. Many failed anti-inflammatory trials likely stem from mismatches in targets, timing, spatial considerations, pathway redundancy, and biomarker selection, rather than invalidating neuroinflammation as a therapeutic target. Recent single-cell and spatial transcriptomic, proteomic, metabolomic, and network-medicine studies offer a framework for precision intervention by identifying inflammatory endotypes, anatomical niches, and pathway modules. We propose the Stage-State-Space Neuroimmune Reprogramming Model (S3-NRM), aligning AD immunotherapy with disease stage, glial/endotype state, and spatial inflammatory niche, guided by fluid, imaging, and omics biomarkers. Future therapies should selectively suppress harmful immune responses while preserving beneficial glial functions.","42440182":"ID: 42440182\nTitle: Silymarin attenuates senescence-exacerbated amyloidogenesis, neuroinflammation, and oxidative stress in lipopolysaccharide-induced memory impairment in aging mice.\nAbstract: Accelerated cellular perturbations such as cellular senescence, neuroinflammation and oxidative stress are hallmarks of Alzheimer's disease, a neurodegenerative disease associated with memory decline. However, the senolytic effects of silymarin, a flavonolignan with known antioxidant and anti-inflammatory properties, on memory decline remain unknown. Hence, we investigated the effect of silymarin on doxycycline-mediated senescence and exacerbated neuroinflammation in lipopolysaccharide-induced memory-impaired mice. Five groups of adult Swiss female mice (n = 10) were exposed to doxycycline-induced accelerated senescence for 21 days, followed by lipopolysaccharide-induced neuroinflammation from days 15-21, and silymarin (50 and 100 mg/kg, p.o.) or donepezil (1 mg/kg, p.o.) treatments. Spatial and non-spatial memory, and social and motor function tests in mice were assessed. Biochemical assays were performed on the prefrontal cortex and hippocampus to assess senescence-associated secretory phenotypes (SASPs), including SA-β-galactosidase activity, cytokines (TNF-α, IL-6, IL-10), amyloid-beta levels, acetylcholinesterase activity, oxidative stress markers, and molybdoenzymes. Doxycycline-lipopolysaccharide-exacerbated memory impairments were reversed by silymarin, accompanied by reduced molybdoenzymes, malondialdehyde, nitrite, and elevated antioxidants (glutathione, superoxide-dismutase, catalase) in the prefrontal cortex and hippocampus. Additionally, silymarin reverses doxycycline-exacerbated lipopolysaccharide-induced increases in IL-6 and TNF-α release and myeloperoxidase activity while also reducing IL-10 levels. Similar to donepezil, silymarin reduced heightened acetylcholinesterase activity associated with doxycycline-enhanced lipopolysaccharide-induced accumulation of cortical SA-β-galactosidase and amyloid-β levels, relative to the doxycycline-lipopolysaccharide group. These findings suggest that silymarin ameliorates doxycycline-lipopolysaccharide-exacerbated memory impairment and modulates senescence and neuroinflammation by reducing oxidative stress, SASP marker levels, and amyloid-beta concentrations in the prefrontal cortex and hippocampus of mouse brains.","42440589":"ID: 42440589\nTitle: P2-engineered exosomes encapsulating curcumin alleviate cognitive decline in AD-like mice by improving microglia-related neuropathology.\nAbstract: Natural exosomes, as drug carriers, can deliver anti-inflammatory agents across the blood-brain barrier (BBB) to lesion sites in the brain, thereby demonstrating immense potential in the treatment of brain inflammation-related diseases. However, the application of natural exosomes is constrained by their poor targeting ability. Herein, we report a novel drug delivery system (P2-Exo-Cur) constructed by engineering exosomes to display the P2 peptide on their surface, thereby enabling targeted delivery of curcumin to microglia. Our results revealed that P2-Exo-Cur possesses a nanoscale membrane structure and can efficiently deliver curcumin to microglia both in vitro and in vivo. This technology provides a microglia-targeted delivery approach for anti-inflammatory agents such as curcumin, while overcoming the undesirable off-target effects that limit their efficacy. Furthermore, treatment of lipopolysaccharide (LPS)-induced inflammatory BV2 cell models with P2-Exo-Cur significantly suppressed the polarization of BV2 cells toward the M1 phenotype, as well as the secretion of pro-inflammatory cytokines. Finally, we also validated the excellent therapeutic potential of this technology in the 5xFAD mouse model. In conclusion, in this study, we for the first time constructed engineered exosomes that can specifically bind to the NCAM protein on microglia to achieve precise delivery of curcumin by expressing the P2 peptide on their surface, exerting beneficial effects in AD treatment without causing significant adverse effects. This strategy may offer a non-invasive and innovative therapeutic method for the management of brain inflammation-related diseases.","42440665":"ID: 42440665\nTitle: The latest research progress of ligustilide in the prevention and treatment of central nervous system disorders.\nAbstract: Ligustilide (LIG), a natural phthalide compound mainly isolated from Angelica sinensis and Ligusticum chuanxiong, has attracted increasing attention because of its diverse pharmacological activities, including anti-inflammatory, antioxidant, anti-apoptotic, and neuroprotective effects. Emerging studies suggest that LIG may have therapeutic relevance in central nervous system (CNS) disorders. This review systematically summarizes the pharmacological effects, molecular mechanisms, pharmacokinetic characteristics, metabolism, safety profile, and therapeutic potential of LIG in CNS disorders. Relevant studies published up to 26 October 2025 were retrieved from PubMed, Web of Science, and Scopus using keywords related to ligustilide, central nervous system disorders, pharmacokinetics, metabolism, and toxicity. After removing duplicate records and excluding reviews, editorials, and irrelevant articles, 55 eligible original studies were included in this review. Current evidence indicates that LIG exerts neuroprotective effects in multiple CNS disorders, including ischemic stroke, cerebral ischemia-reperfusion injury, vascular dementia, Alzheimer's disease, Parkinson's disease, traumatic brain injury, and anxiety disorders. Its mechanisms mainly involve modulation of PI3K/Akt, MAPK, NF-κB, Nrf2/ARE, AMPK, and other signaling pathways, leading to reduced oxidative stress, inflammation, apoptosis, and mitochondrial dysfunction. In addition, available studies suggest that LIG can cross the blood-brain barrier and shows relatively favorable safety in preclinical models. LIG demonstrates broad neuroprotective potential in preclinical studies and may represent a promising candidate for CNS disease intervention. However, its poor chemical stability, low oral bioavailability, limited toxicity evaluation, and lack of clinical evidence remain major challenges for translational application. Further studies are required to optimize delivery strategies and validate its efficacy and safety in clinical settings.","42440686":"ID: 42440686\nTitle: Comparison of safety of lecanemab and donanemab: a real-world disproportionality analysis using the FDA adverse event reporting system.\nAbstract: Lecanemab and donanemab are anti-amyloid-β (Aβ) monoclonal antibodies recently approved for the treatment of Alzheimer's disease (AD). Although both agents have demonstrated therapeutic potential, their post-marketing adverse event reporting profiles remain insufficiently characterized and compared in spontaneous reporting systems. This study aimed to systematically compare adverse event signals associated with these two drugs using the FDA Adverse Event Reporting System database, with sex-stratified and sensitivity analyses performed to support the main findings. FAERS reports up to the fourth quarter of 2025 were retrospectively analyzed. Reports in which lecanemab or donanemab was recorded as the primary suspect drug were included. AEs were classified by system organ classes (SOCs) and preferred terms (PTs) according to the Medical Dictionary for Regulatory Activities (MedDRA). Signal detection was performed using four algorithms: reporting odds ratio (ROR), proportional reporting ratio (PRR), Bayesian confidence propagation neural network (BCPNN), and multi-item gamma Poisson shrinker (MGPS). Sex-stratified analysis, sensitivity analysis after excluding reports involving concomitant medications, and time-to-onset (TTO) analysis based on the Weibull shape parameter model were also conducted. False discovery rate (FDR) correction was applied to analyses involving multiple P values. A total of 3,640 AE reports were identified, including 2,602 for lecanemab and 1,038 for donanemab. Nervous system disorders was the most frequently reported SOC and the only SOC meeting the positivity criteria across all four algorithms for both drugs. At the PT level, the frequently reported events for both drugs were mainly concentrated in amyloid-related imaging abnormality (ARIA)-related events, including ARIA with oedema/effusion (ARIA-E) and ARIA with microhaemorrhages/haemosiderin deposition (ARIA-H), headache, and infusion-related reactions. The strongest disproportionality reporting signals were mainly observed for ARIA-related preferred terms and cerebral microhaemorrhage. In separate FAERS-based disproportionality analyses, lecanemab showed stronger disproportionality reporting signals for ARIA-H, whereas donanemab showed stronger disproportionality reporting signals for ARIA-E. In addition, drug-specific PT signal distributions differed between the two agents. Several potential novel PT signals were also identified. Sex-stratified analysis suggested differences in the distribution of certain PT signals between female and male reports. Sensitivity analysis supported the stability of most core signals. The median TTO was 46 days for lecanemab and 31 days for donanemab, and Weibull analysis suggested different temporal patterns of AE occurrence. Using four signal detection algorithms, this study compared real-world adverse event reporting profiles associated with lecanemab and donanemab. The two drugs showed both shared and distinct adverse event reporting profiles, particularly in ARIA subtype-related disproportionality signals, drug-specific PT signals, potential novel reporting signals, sex-stratified reporting patterns, and TTO characteristics. These findings provide pharmacovigilance evidence for targeted safety monitoring and hypothesis generation, but should not be interpreted as causal associations or true incidence estimates.","42440728":"ID: 42440728\nTitle: Reprogramming lipid metabolism for cognitive restoration in Alzheimer's via PLA2G4E.\nAbstract: Growing evidence implicates dysregulated brain lipid metabolism in Alzheimer's disease (AD) pathogenesis, influencing membrane integrity, neuroinflammation, and amyloid beta and tau pathology, thereby representing a promising therapeutic target. However, therapeutic strategies targeting lipid pathways remain largely unexplored. The therapeutic potential of PLA2G4E, previously identified in our earlier work, was validated in the APPNL-G-F AD mouse model using a translational gene-delivery approach with a blood-brain barrier-penetrant adeno-associated vector (AAV) (AAVP31) to achieve widespread brain expression. Brain lipidomics was performed to investigate the molecular mechanisms underlying treatment effects. PLA2G4E expression rescued memory deficits, reduced tau phosphorylation, and improved brain glucose metabolism and cognitive performance in AD models and aged wild-type mice. These effects were accompanied by partial normalization of disease-associated lipid metabolic alterations. These findings support PLA2G4E as a promising therapeutic target in AD and provide mechanistic evidence linking modulation of lipid metabolic pathways to synaptic and cognitive rescue.","42441363":"ID: 42441363\nTitle: Longitudinal changes in DTI-ALPS and choroid plexus volume relative to CSF biomarkers during lecanemab treatment in mild cognitive impairment: A pilot study.\nAbstract: Lecanemab improves cerebrospinal fluid (CSF) biomarkers, but whether magnetic resonance imaging (MRI) proxies of CSF-interstitial fluid (ISF) exchange improve is unknown. This was a single-center prospective pilot (n = 8). The ALPS index was derived from diffusion tensor image analysis along the perivascular space (DTI-ALPS), and intracranial volume (ICV)-normalized choroid plexus (ChP) volume was segmented with FreeSurfer Sequence Adaptive Multimodal SEGmentation (SAMSEG). Baseline changes were tested with Wilcoxon signed-rank tests with Benjamini-Hochberg false discovery rate (FDR) control within prespecified MRI, CSF, and cognition endpoint families. CSF Aβ42 and Aβ42/40 increased and tau phosphorylated at threonine 181 (p-tau181) decreased at 6 and 12 months (all q < 0.05); cognition showed no FDR-significant change. The ALPS index showed a downward tendency (9-month q = 0.010), and ChP/ICV increased at 6-12 months (all q = 0.010). The ALPS index and ChP volume may be insufficient as stand-alone surrogate endpoints over 12 months. These findings suggest exploring complementary strategies targeting CSF-ISF exchange and clearance pathways and warrant larger controlled longitudinal studies. Not applicable (observational study).","42441515":"ID: 42441515\nTitle: Evaluating Triptolide Effects on Hippocampal Gephyrin, Collybistin, and Autophagy in an Aβ1-42 Mouse Model.\nAbstract: Alzheimer's disease is associated with synaptic dysfunction, but standardized procedures for evaluating how Aβ-induced pathology affects inhibitory synapse-associated proteins and autophagy-related signaling after candidate intervention remain limited. This protocol describes a workflow for establishing an Aβ1-42-induced Alzheimer's disease-like mouse model and assessing the effects of triptolide on hippocampal Gephyrin, Collybistin, PI3K/Akt/GSK-3β signaling, and autophagy-related markers. Adult C57BL/6J mice receive bilateral intracerebroventricular injection of Aβ1-42 prepared under aggregation-inducing conditions, followed by daily intraperitoneal administration of triptolide with or without the PI3K inhibitor LY294002. Spatial learning and memory are evaluated using Morris water maze testing. Hippocampal neuronal injury and Aβ deposition are assessed by hematoxylin and eosin staining and Aβ immunohistochemistry, and hippocampal lysates are analyzed by Western blotting to quantify Gephyrin, phosphorylated Gephyrin, Collybistin, PI3K/Akt/GSK-3β signaling proteins, LC3-II/I, and p62. Key procedural considerations include standardized Aβ1-42 preparation, accurate stereotaxic injection, consistent behavioral testing conditions, blinded region-of-interest selection, and standardized image and densitometry analysis. Using this workflow, Aβ1-42 administration produced spatial learning and memory deficits, hippocampal neuronal injury, Aβ deposition, reduced Gephyrin and Collybistin expression, altered PI3K/Akt/GSK-3β signaling, and increased LC3-II/I and p62 accumulation. Triptolide partially reversed these behavioral, histological, and molecular changes, whereas LY294002 attenuated its effects. This protocol can be used to evaluate Aβ-induced hippocampal molecular alterations and candidate interventions, while recognizing that this model does not reproduce the chronic, multifactorial progression of human Alzheimer's disease.","42441681":"ID: 42441681\nTitle: [Social Cognition and Theory of Mind as a Differential Marker Between Alzheimer's Disease and Behavioral Variant Frontotemporal Dementia].\nAbstract: While language, memory, and executive function have been proposed as differential markers between Alzheimer's disease (AD) and behavioral variant frontotemporal dementia (bvFTD), recent studies emphasize the role of Social Cognition (SC) and Theory of Mind (ToM) in distinguishing between these conditions. To characterize SC and ToM performance in patients with AD and bvFTD. This review followed PRISMA guidelines and included studies published between January 2015 and March 2024 from PubMed, Scopus, and Web of Science. Fourteen studies were critically analyzed. Findings suggest that SC and ToM are impaired in both disorders. In AD, the main deficits involve emotional recognition and perception, and social behavior. In bvFTD, common impairments include decision-making, emotion recognition, social behavior, and empathy loss. SC and ToM may support the differential diagnosis between AD and bvFTD, particularly in early stages. Further research is needed to develop standardized assessments for clinical use to detect and classify the severity of SC and ToM decline.","42442566":"ID: 42442566\nTitle: Sleep-Related Alzheimer's Disease Vulnerability in Aging: A Muscle-Metabolic Perspective.\nAbstract: Sleep disruption is a hallmark of aging and a plausible driver of Alzheimer's disease vulnerability. Reduced slow-wave sleep, increased fragmentation, and circadian instability may facilitate amyloid-β accumulation, tau propagation, neuroinflammation, oxidative stress, and impaired glymphatic clearance. Yet the physiological factors that predispose older adults to unstable sleep remain insufficiently integrated into models of brain aging. This Review advances a sleep-muscle-brain framework in which sarcopenia, sarcopenic obesity, and insulin resistance are conceptualized as modifiable muscle-metabolic conditions that may bias sleep continuity and shape the biological impact of sleep disruption. We examine irisin/FNDC5-BDNF signaling as a hypothesis-generating candidate modifier of metabolic regulation, neurotrophic support, and brain resilience, while emphasizing that direct evidence for a causal role in human sleep regulation remains insufficient. Irisin-related pathways intersect with insulin sensitivity, inflammatory control, and BDNF-dependent synaptic plasticity, all of which are relevant to the physiological context in which sleep disruption may influence Alzheimer's disease pathophysiology. We propose that age-related attenuation of muscle endocrine signaling, together with insulin resistance and low-grade inflammation, may lower the threshold at which sleep fragmentation translates into amyloid/tau dyshomeostasis, glial activation, and network dysfunction. Rather than treating sleep disturbance as an isolated brain-centered risk factor, this framework positions sleep as a biobehavioral hub through which peripheral aging processes can modulate neurodegenerative resilience. The Review integrates evidence from sleep neuroscience, geroscience, metabolism, and neurodegeneration, and identifies experimentally testable predictions. A sleep-muscle-brain perspective may help refine risk stratification and guide multimodal interventions combining sleep optimization, resistance exercise, metabolic targeting, and Alzheimer's disease biomarker monitoring.","42442802":"ID: 42442802\nTitle: The Role of Genetic Alterations in the Emergence of Alzheimer's Disease in Down Syndrome: A Review.\nAbstract: Down syndrome (DS), the most common chromosomal disorder, is associated with an accelerated aging process, increasing the risk of early-onset Alzheimer's disease. This review examines genetic factors involved in the development of Alzheimer's disease (AD) in people with DS. A systematic search in major databases was conducted, and articles from 2020 to 2025 that met the predefined inclusion criteria were included. The results showed that the prevalence of AD was above 60% in people with DS older than 65 years, the mean age at diagnosis was 53 years, and the mortality occurred around 59 years. The main genetic factor identified was the overexpression of the APP gene, along with other genes such as DYRK1A, RCAN1, SOD1, APOEε4, and genes involved in the immune response, as well as posttranscriptional dysregulation. Diagnosis remains a challenge due to the pre-existent intellectual disability and the atypical clinical presentation of the disease; however, the development of adapted neuropsychological tests, biomarkers, and neuroimaging techniques is expected to facilitate early diagnosis. The connection between both diseases is the result of multiple genetic factors that lead to early onset and accelerated progression of AD. It is essential to achieve timely diagnosis and provide early treatment to improve quality of life of both patients and their caregivers.","42442908":"ID: 42442908\nTitle: Role of ESCRT pathway and autophagy in neurodegenerative diseases.\nAbstract: Neurodegenerative diseases are characterized by progressive neuronal dysfunction and loss resulting from impaired proteostasis and vesicular trafficking. Neurons are particularly vulnerable to these processes due to their post-mitotic nature and complex architecture. Autophagy and the endolysosomal system constitute the primary degradative pathways responsible for maintaining neuronal homeostasis. However, increasing evidence indicates that their effective function critically depends on coordination with the endosomal sorting complexes required for transport (ESCRT). Beyond their canonical role in multivesicular body biogenesis and membrane scission, ESCRT components are now recognized as essential regulators of autophagosome closure, amphisome formation, autophagosome-lysosome fusion, and endolysosomal membrane repair. Disruption of this ESCRT-autophagy interface has emerged as a common pathological feature across major neurodegenerative disorders, including Alzheimer's disease, Parkinson's disease, and amyotrophic lateral sclerosis/frontotemporal dementia. This review synthesizes evidence from genetic, biochemical, and neuropathological studies to highlight shared molecular nodes, such as ESCRT-III components, the VPS4 ATPase, the adaptor protein ALIX, and late endosomal regulators, including Rab7, that couple membrane remodeling to autophagic flux. Failure of these regulatory checkpoints destabilizes endolysosomal integrity, arrests autophagic maturation, and promotes the accumulation of toxic protein species, thereby driving progressive neuronal degeneration. By framing neurodegeneration through the lens of ESCRT-autophagy coupling failure, this review provides a unified mechanistic perspective that links diverse pathogenic proteins to shared cellular vulnerabilities and identifies ESCRT-mediated membrane dynamics as a critical determinant of neuronal survival.","42442912":"ID: 42442912\nTitle: Metallospecies and their biological functions in Alzheimer's disease.\nAbstract: This chapter critically explores the role of metallospecies homeostasis in the pathophysiology of Alzheimer's disease (AD), going beyond the traditional amyloid protein-centered approach. The discussion integrates biochemical, molecular, and analytical perspectives to elucidate how metal-biomolecule interactions influence protein misfolding, protein aggregation, and neurotoxicity. Furthermore, the chapter reviews cutting-edge metallomic approaches, including advanced speciation analyses and metal bioimaging techniques, to demonstrate how these tools allow for the precise characterization of the chemical identity, coordination environment, and spatial distribution of metal species in brain tissue. By discussing mechanistic insights with analytical advances, this chapter provides a comprehensive framework for understanding the contribution of metal dysregulation to AD and identifies new directions for diagnosis and therapeutic intervention.","42442914":"ID: 42442914\nTitle: Metabolic reprogramming in Alzheimer's disease: Interaction between receptor tyrosine kinase signaling, noncoding RNAs, and Neuron-Glia energy networks.\nAbstract: Alzheimer's disease (AD) is increasingly understood as a disorder involving impaired brain energy metabolism rather than being solely caused by amyloid and tau pathology. This chapter offers a comprehensive overview of how glucose hypometabolism, mitochondrial dysfunction, and disrupted neuron-astrocyte metabolic coupling collectively creates an \"energy crisis\" in vulnerable neuronal circuits. Early issues with glucose transport (GLUT1/3/4), reduced glycolytic flux, TCA cycle problems, and excessive mitochondrial fission all contribute to decreased ATP production and increased oxidative stress. Along with these metabolic disturbances, receptor tyrosine kinase (RTK) pathways-including insulin/IGF-1, TrkB/BDNF, FGFRs, and EGFR-lose their regulatory control, leading to insulin resistance, synaptic failure, and increased vulnerability to Aβ and tau toxicity. The chapter also highlights noncoding RNAs (miRNAs and lncRNAs) as key post-transcriptional regulators of metabolic and RTK signaling networks. Harmful miRNAs (such as miR-34a, miR-210-3p) suppress glycolytic enzymes and mitochondrial genes, while protective miRNAs (miR-23a/b, miR-455-3p, miR-195) decrease in AD. Metabolic lncRNAs, like EPB41L4A-AS1, decline with age and contribute to NAD⁺ depletion and bioenergetic imbalance. Recognizing the link between RTK dysregulation and ncRNA-driven metabolic control reveals new therapeutic possibilities to restore mitochondrial function, enhance neurotrophic support, and re-establish energy balance in the AD brain.","42442916":"ID: 42442916\nTitle: Metabolic drivers of Alzheimer's disease pathogenesis: Impairments in glucose utilization, lipid homeostasis, and alternative substrate metabolism.\nAbstract: Alzheimer's disease (AD) is one of the widespread neurodegenerative disorders, marked by the accumulation of amyloid-β plaques, neurofibrillary tangles of hyperphosphorylated Tau protein, and the gradual loss of neurons. While genetic and environmental factors have been associated with its onset, metabolic dysfunction has also been identified as one of the initial and most significant contributors its pathogenesis. The mitochondria are at the centre of this problem; their compromised function affects some crucial aspects of the neuronal health. Neurons have high energy demands so they are quite sensitive to the changes in the supply of the fuel. During AD pathogenesis, the loss of glucose transporters and the downregulation of key glycolytic enzymes deprives neurons of essential energy reserve. This metabolic dysregulation is further exacerbated by dysregulated lipid metabolism, pathological lipid droplet accumulation and ApoE4-driven failures in lipid trafficking which collectively leads to the oxidative stress, neuroinflammation, and Aβ aggregation. This situation is further aggravated by amino acid imbalances specifically within the glutamate-glutamine cycle. To counter this, ketone bodies have emerged as an alternative fuel source, capable of partially bypassing the impaired glucose oxidation while also demonstrating neuroprotective properties. Moreover, systemic metabolic disorders including type 2 diabetes mellitus, insulin resistance, obesity, and metabolic syndrome significantly amplify these deficits, functioning as major risk factors for AD onset and progression. Even the gut-brain axis plays a role in adding to the complexity. Taken together, these metabolic health changes not only reshape our understanding of AD but also open potential prospects for early detection through metabolic biomarkers and for novel therapeutic strategies targeting mitochondrial bioenergetics, glucose restoration, and ketogenic interventions.","42442917":"ID: 42442917\nTitle: Glial molecular signatures as a liquid biopsy marker in Alzheimer's disease diagnosis.\nAbstract: Alzheimer's disease (AD) is a neurodegenerative condition that is characterized by the misfolding of Amyloid Precursor Protein, hyperphosphorylation of tau protein, and neuroinflammation. This leads to the formation of extracellular senile amyloid beta plaque and neurofibrillary tangles in neurons, leading to neuronal degeneration. AD is the biggest cause of dementia globally. Currently, no therapies are available for AD and early diagnosis of the disease is a challenge. The most common fluid biomarkers for AD are: p-tau181, p-tau231, p-tau217, Aβ42/Aβ40 ratio, Neurogranin (Ng), Alzheimer's-associated neuronal thread protein (AD7c-NTP). All these biomarkers are detected in Blood, CSF, Saliva, and Urine with the help of different assays, PET scan, and MRI Imaging. These biomarkers are of neuronal origin and indicate neuronal stress. Brain also contains glial cells along with the neurons, which interact with the neurons in health and disease conditions. These glial cells also release molecules in disease induced stress. These markers can be used for early and differential diagnosis of AD and other dementia conditions. Studies also show that these glia biomarkers are released decades before the actual neuron degeneration begins. In this review, we will discuss these glial cells biomarkers identified in liquid biopsy for AD detection and progression.","42442918":"ID: 42442918\nTitle: Insulin resistance and obesity: Drivers of energy crisis for Alzheimer's disease.\nAbstract: Alzheimer's disease (AD) is increasingly recognized as a disorder driven not only by classical neuropathological hallmarks but also by profound disturbances in brain energy metabolism. Growing evidence points to insulin resistance and obesity as major contributors to this metabolic crisis, linking peripheral metabolic dysfunction to central neurodegenerative processes. This chapter explores AD in the light of bioenergetic failure, highlighting the epidemiological and mechanistic connections between impaired insulin signaling, excess adiposity, and cognitive decline. The chapter further highlights how obesity-related inflammation, adipokine imbalance, and gut-brain axis dysregulation accelerates central insulin resistance and neuronal vulnerability. Evidence for glucose hypometabolism, mitochondrial failure, and disrupted astrocyte-neuron metabolic coupling in AD is reviewed, positioning amyloid and tau pathology as downstream consequences of sustained energy insufficiency. Finally, emerging therapeutic strategies aimed at restoring metabolic balance ranging from insulin-based interventions to lifestyle and mitochondria-targeted approaches are discussed, underscoring the potential of metabolic restoration as a disease-modifying strategy in Alzheimer's disease.","42442919":"ID: 42442919\nTitle: Therapeutic targeting of brain bioenergetics in Alzheimer's disease addressing insulin resistance, glucose hypometabolism, and mitochondrial dysfunction.\nAbstract: Alzheimer's disease (AD) is a progressive, age-associated multifactorial neurodegenerative disorder characterised by cognitive decline, synaptic dysfunction, and neuronal loss. Despite over a century of research, effective disease-modifying therapies remain elusive owing to its conundrum pathophysiology. In recent years, AD is increasingly recognised as a complex metabolic disorder characterised by impaired cerebral glucose metabolism, insulin resistance, and mitochondrial dysfunction. These interconnected metabolic disturbances emerge early in the disease state and collectively potentiate other pathologies such as accumulation of amyloid-β (Aβ) plaques, tau hyperphosphorylation, oxidative stress, neuroinflammation, and synaptic dysfunction, thereby establishing bioenergetic failure as a primary factor governing AD progression rather than a downstream phenomenon. While traditional drug development strategies targeting Aβ have failed in clinical trials (limited to monoclonal antibodies), emerging therapeutic models integrating energy failure, thiamine signalling, and insulin-like growth factor (IGF) signalling as upstream events show significant promise in countering downstream neurodegeneration. This chapter summarises the mechanistic framework linking bioenergetic breakdown to AD pathology, with potential therapeutic opportunities aimed at restoring mitochondrial function, enhancing glucose utilisation, and correcting insulin signalling, further opening new avenues for multimodal interventions and identification of progressive metabolic dysfunction biomarkers to aid diagnostic processes.","42443390":"ID: 42443390\nTitle: PIAS1-mediated GSK3β SUMOylation exacerbates tauopathy and cognitive deficits in Alzheimer's disease models.\nAbstract: Age-related neurodegenerative disorders, such as Alzheimer's disease (AD), are characterized by the accumulation of pathological Tau protein (tauopathy), which drives neurotoxicity and cognitive decline. Although SUMOylation significantly influences tauopathy, the underlying mechanisms remain largely elusive. Here, utilizing a bimolecular fluorescence complementation (BiFC) assay to monitor Tau-Tau aggregation and screen for SUMO E3 ligases, we identified PIAS1 as a critical driver of Tau pathology. Genetic analysis of the UK Biobank cohort revealed that single nucleotide polymorphisms in the PIAS1 gene (rs8036154 and rs112677781) are significantly associated with a reduced risk of AD. Consistent with this clinical relevance, PIAS1 expression is upregulated in postmortem AD brains, aging PS19 tauopathy mice, aged wild-type mice, aged lemurs, and neurons stimulated with amyloid-beta or lipopolysaccharide. Viral-mediated modulation of PIAS1 in vivo demonstrated that PIAS1 promotes Tau hyperphosphorylation and aggregation, thereby exacerbating synaptic dysfunction and cognitive deficits. Mechanistically, we found that PIAS1 directly interacts with and mediates the SUMOylation of glycogen synthase kinase 3 beta (GSK3β) at lysine residues 183 and 271. This specific SUMOylation reduces inhibitory phosphorylation at Ser9, consequently enhancing GSK3β-mediated Tau kinase activity. Importantly, we engineered a cell-permeable blocking peptide designed to disrupt the PIAS1-GSK3β interaction. Administration of this peptide effectively suppressed GSK3β activation and mitigated tauopathy and neurodegeneration in both in vitro and in vivo models. Together, our findings uncover a novel PIAS1-GSK3β signaling axis in tauopathy and provide a promising targeted therapeutic strategy for Alzheimer's disease.","42443567":"ID: 42443567\nTitle: Standardized Extract of Ginkgo biloba L. Reverses Memory Impairment in Older Female Mice with Basal Forebrain Cholinergic Dysfunction.\nAbstract: Aging induces neurochemical changes, particularly in the dentate gyrus (DG), that impair memory. In late-onset Alzheimer's disease (LOAD), neuronal loss in regions like the entorhinal cortex (EC) and hippocampus proper (HP), along with amyloid-β (Aβ) plaques, tau tangles, and reduced cholinergic signaling, accelerates cognitive decline. Building on our group's previous findings of cognitive benefits and neuroprotection from Ginkgo biloba L. leaf extract (EGb), and considering the limited success of current therapies, EGb has emerged as a promising multi-target strategy for reversing memory impairments. This study evaluates the effects of chronic EGb treatment on memory, anxiety-like behaviors, and motor activity in older female wild-type and VAChT knockdown KDHET and KDHOM mice, which show 45% and 65% reductions in VAChT expression, respectively. We assessed the impact of EGb on Aβ1-42 peptide and phosphorylated tau (pTauT231) by quantifying Aβ IR+ and pTau IR+ cells in the dCA1, dCA3, and dDG, via immunohistochemistry. Results showed that aging led to short- and long-term memory deficits, which were exacerbated in the VAChT KDHOM mice. However, EGb treatment reversed these deficits in a dose-dependent manner by modulating Aβ and pTau-IR+ cells in the dCA1, and dDG regions. In vitro, EGb significantly inhibited Aβ aggregation through interactions with Aβ and the POPC monolayer. These findings suggest that EGb may provide a promising therapeutic strategy for AD, improving cognition and offering neuroprotection by targeting key neuropathological features like Aβ plaques and phosphorylated tau.","42443581":"ID: 42443581\nTitle: Rethinking blood-brain barrier permeability in Alzheimer's disease: insights from APOE genotype-specific associations.\nAbstract: ","42443606":"ID: 42443606\nTitle: Tau physiology and pathology: impacts on cellular structures and neurodegenerative diseases.\nAbstract: This review explores the crucial roles of the tau protein in neuronal integrity and its dysregulation in neurodegenerative diseases (NDs), particularly tauopathies. Key features include abnormal tau phosphorylation, leading to insoluble aggregates and neuronal dysfunction. Various therapeutic strategies, such as reducing tau phosphorylation, inhibiting aggregation, and enhancing clearance through autophagy and immunotherapies, are discussed. Promising candidates such as anle138b and methylene blue display efficacy in preclinical models. The interplay between tau and Aβ pathology is also highlighted, emphasizing the complexity of therapeutic approaches. A thorough understanding of tau functions is essential for developing targeted treatments to combat tau-related neurotoxicity and advance therapies for Alzheimer's disease (AD). This article examines the dual role of tau in physiology and pathology, highlighting its effects at both the cellular and subcellular levels. These findings underscore the critical importance of the tau protein in preventing NDs and suggest that a deeper understanding of its functions could improve treatment strategies for tau-related disorders.","42443949":"ID: 42443949\nTitle: CIT-Lasso: a scalable approach beyond guilty by association for identifying causal variants from genome-wide summary statistics.\nAbstract: We present CIT-Lasso, a framework that uses only summary statistics to identify, genome-wide, sets of variants carrying non-redundant information on a phenotype, distinguishing likely causal variants from correlated variants that are merely associated.

Microglia, the brain's resident immune cells, centrally regulate AD pathophysiology. Recent studies have highlighted microglial mitophagy as an important interface linking mitochondrial quality control to innate immune responses.Intact mitophagy facilitates the timely clearance of damaged mitochondria, thereby limiting the release of mitochondrial DAMPs (e.g., mtDNA and mtROS) and helping restrain aberrant activation of the cGAS-STING pathway and the NLRP3 inflammasome.In the AD pathological milieu, however, factors including Aβ deposition, tau pathology, and genetic risk variants such as TREM2 and APOE4 disrupt mitophagy at multiple levels-from initiation and recognition to lysosomal degradation. This review systematically summarizes the molecular regulatory network of microglial mitophagy, with a particular focus on the mechanisms by which AD-associated pathological factors impair this process. We further discuss potential mechanisms through which mitophagic dysfunction may contribute to the amplification of neuroinflammation, including the release of mitochondrial DAMPs, the reprogramming of TBK1 signaling, and intercellular interactions. Finally, we outline current therapeutic strategies aimed at restoring mitophagy and discuss their potential to modulate neuroinflammatory responses and AD-related pathological processes, while highlighting the challenges and future directions in this emerging field.","42443969":"ID: 42443969\nTitle: Breaking the glial loop: astrocytic PAD2 and citrullinated vimentin drive microglial dysfunction in Alzheimer's disease.\nAbstract: Zhang et al. reveal that astrocytic PAD2-mediated citrullination of vimentin drives a TLR4-dependent pro-inflammatory loop in microglia, linking glial crosstalk to impaired amyloid clearance and identifying a potential therapeutic and biomarker pathway in Alzheimer's disease.","42444063":"ID: 42444063\nTitle: EXPRESS: Ultrasound Enhances Glymphatic-Associated Solute Transport via Piezo1-Related Mechanotransduction in 5xFAD Mice.\nAbstract: Glymphatic dysfunction impairs Aβ clearance and contributes to Alzheimer's disease (AD) progression. Low-intensity transcranial focused ultrasound (LITFUS) can enhance glymphatic cerebrospinal fluid transport, but its therapeutic effects on Aβ clearance and cognitive decline remain unclear. 5xFAD mice received bilateral hippocampal LITFUS for 4 weeks. Glymphatic transport was assessed by fluorescent tracer injection and ex vivo imaging. Aβ deposition, Iba1 immunoreactivity, and cognitive function were evaluated by immunohistochemistry and behavioral tests. Piezo1 involvement was examined using GsMTx4, qPCR, and Western blotting of isolated brain vascular fractions. Safety was assessed by blood-brain barrier permeability and H&E staining. LITFUS increased brain-wide CSF tracer influx and hippocampal interstitial solute clearance in 5xFAD mice. It reduced Aβ deposition in the hippocampus and prefrontal cortex, decreased Iba1 immunoreactivity, and improved learning and memory. These effects were associated with increased Piezo1 expression and enhanced CaMKII/eNOS signaling in brain vascular fractions, and were attenuated by GsMTx4. No blood-brain barrier disruption or histological injury was detected. LITFUS enhances glymphatic transport, reduces cerebral Aβ burden, and improves cognition in 5xFAD mice, possibly through Piezo1-related mechanotransduction, supporting its potential as a noninvasive AD therapy.","42444286":"ID: 42444286\nTitle: Vascular-Apoptotic Crosstalk in Alzheimer's Disease: The Possible Role of Vascular Senescence in Blood-Brain Barrier Dysfunction.\nAbstract: Blood-brain barrier (BBB) dysfunction is an early feature of Alzheimer's disease (AD), influenced by amyloid pathology, astrocyte activation, and vasoactive mediators such as endothelin-1 (ET-1). ET-1 has been implicated in apoptosis and vascular senescence through induction of p53, a pro-apoptotic factor, whereas BCL-X exerts antiapoptotic effects. We investigated the interplay between ET-1, p53, and BCL-X in AD and their contribution to BBB permeability. We studied 101 individuals (70 AD, 31 controls) who underwent cerebrospinal fluid (CSF) analysis for Aβ42, p-tau, ET-1, p53, BCL-X, and the CSF/serum albumin quotient (QAlb), an index of BBB permeability. Correlations between biomarkers were explored, followed by multiple regression and mediation analysis to assess whether p53 mediated the ET-1-BBB relationship. No absolute differences in ET-1, p53, or BCL-X were found between AD and controls. However, in AD, ET-1 correlated positively with p53 and negatively with BCL-X, whereas no such associations were seen in controls. None of these biomarkers related to the p-tau/Aβ42 ratio. Regression analysis identified both ET-1 and p53 as independent predictors of BBB permeability. Mediation analysis further revealed that ET-1 influenced BBB permeability both directly and indirectly through p53. Our findings suggest that AD is characterized less by absolute biomarker changes and more by altered interrelationships linking ET-1, apoptosis, and BBB integrity. ET-1 may promote BBB dysfunction partly via p53, which is consistent with the mechanisms of vascular senescence. These results highlight apoptosis-vascular interactions as potential drivers of BBB impairment in AD.","42444329":"ID: 42444329\nTitle: Young Adult Microglial Deletion of C1q Reduces Engulfment of Synapses and Partially Mitigates Cognitive Impairment in an Aggressive Alzheimer's Disease Mouse Model.\nAbstract: C1q is a multifunctional protein, including its role as the initiating protein of the classical complement cascade. While classical pathway activation is involved in synaptic pruning during nervous system development, it also contributes to inflammation and cognitive decline in Alzheimer's disease (AD). Constitutive genetic C1q deficiency has been shown to reduce glial activation and attenuate neuronal loss in AD mouse models, but the specific contributions of microglial C1q to AD pathology while avoiding deficits during post-natal development remain unaddressed. To dissect specific role(s) of microglial C1q in AD progression, we crossed the Cx3cr1CreERT2 mouse model that deletes C1q from microglia in young adulthood (8 weeks of age) to the aggressive Arctic48 (Arc) amyloidosis mouse model. At 10 months, young adult microglial C1q deletion (Arc C1qΔMG) was associated with improved spatial memory performance, despite unchanged amyloid plaque burden. Furthermore, Arc C1qΔMG mice exhibited reduced hippocampal C3 protein levels without altering C3 mRNA. No changes were observed in C5aR1, astrocyte GFAP, or microglial Iba1 protein expression. However, Arc C1qΔMG mice demonstrated region specific reductions in microglial synaptic engulfment, alongside decreased phagolysosome-associated amyloid in both microglia and astrocytes, and reduced hippocampal amyloid compaction. These findings support a role for C1q in astrocytic C3 induction and the engulfment of both synapses and amyloid. Importantly, young adult microglial C1q inhibition confers cognitive benefits without exacerbating amyloid pathology, suggesting a therapeutic window in which targeting microglial C1q may help preserve synaptic integrity and modulate the neuroinflammatory processes during the later stages of AD.","42444486":"ID: 42444486\nTitle: Branched-chain amino acids and gut microbiota: coregulation and impact on neurological function via the gut-brain axis.\nAbstract: Diseases that cause neurological dysfunction, such as Parkinson's disease (PD), Alzheimer's disease (AD), and maple syrup urine disease (MSUD), among others, are characterized by complex and multifaceted etiologies. There is growing evidence that branched-chain amino acids (BCAAs), regulated by the gut microbiota, play a critical role in the development of the central nervous system (CNS) disorders. This review focuses on the potential role of branched-chain amino acid metabolism in regulating brain function and gut microbiota. First, we summarize the current understanding of BCAAs, encompassing their biochemical metabolism, function, and systemic metabolic mechanisms. Subsequently, we delve into the mechanisms through which the gut microbiota regulates branched-chain amino acid metabolism, along with its mechanistic insights and recent evidence of its impact on neurological disorders. Finally, we discuss future research directions and challenges regarding gut BCAAs metabolism as a potential treatment for brain and gastrointestinal dysfunction.","42444503":"ID: 42444503\nTitle: A First-In-Class Antibody Enabling Detection of Altered Peripheral Non-Phosphorylated Clusterin With Translational Potential in Dementia.\nAbstract: Clinical diagnosis of dementia, with Alzheimer's disease (AD) as the major form, relies heavily on memory tests and the caregiver descriptions, both of which are subjective. The discovery of reliable biomarkers may facilitate objective diagnosis. The protein clusterin (CLU), encoded by a well-established AD risk gene, is consistently elevated in AD patients, but its biomarker utility is limited by high interindividual variability. As CLU is produced in most organs and tissues, quantifying CLU secreted specifically from the brain into the bloodstream may help the development of new diagnostic methods. CLU in blood can be phosphorylated at T393-S394 and/or S396, but these phosphorylations are absent in brain parenchyma. Peripherally administered non-phosphorylated CLU has been shown to reduce neuroinflammation and AD pathology in mouse models. A monoclonal antibody, 3D3F10, targeting non-phosphorylated CLU at T393-S394 or S396 was generated. This antibody showed an ability to distinguish serum samples of dementia and non-dementia (p < 0.001, AUC = 0.897, sensitivity: 81.8%, specificity: 95.5%, Youden index: 0.77), but did not distinguish Parkinson's disease. The direction of the change contradicted our initial hypothesis, and further analyses suggested that phospho-CLU in dementia patients is unlikely to originate from the brain. These results established 3D3F10 as a novel tool for modification-specific CLU detection, indicated a potential of non-phospho-CLU as a biomarker for dementia, and peripheral phospho-CLU might play a role in pathogenesis.","42444591":"ID: 42444591\nTitle: Self-Assembly of Antigenic Peptide Nanofibrils Templates the Growth of Silica Nanoparticles for Nanovaccines.\nAbstract: The low immunogenicity of peptide vaccines remains a critical challenge in immunotherapy. While peptide nanofibrils can function as self-delivery systems to activate antigen-presenting cells (APCs), most existing designs rely on complex covalent conjugation to β-sheet-forming motifs. Moreover, the diverse surface properties of various antigenic peptides complicate the rational selection of appropriate adjuvants. Herein, we develop a nanovaccine platform in which antigenic peptides self-assemble into nanofibrils without the need for exogenous β-sheet-forming sequences. Silica nanoparticles (SiO2 NPs) are nucleated and grown directly along these fibrils, resulting in SiO2@fibril nanovaccines with a unique \"beads-on-a-string\" morphology. Using amyloid-β(1-42) (Aβ42) and human papillomavirus (HPV) type 16 E7 (E7) as model antigens, we demonstrate that these nanovaccines significantly enhance the maturation and activation of bone marrow-derived dendritic cells (BMDCs). In an Alzheimer's disease animal model using APP/PS1 mice, SiO2@Aβ42 nanovaccines improve motor and cognitive function. Additionally, in an HPV animal model using TC-1 tumor-bearing mice, SiO2@E7 nanovaccines suppress tumor growth and increase survival rate. This strategy provides a universal and modular adjuvant platform for peptide-based nanovaccines.","42444728":"ID: 42444728\nTitle: Associations among mild behavioral impairment, cognition, and brain pathology in preclinical autosomal dominant Alzheimer's disease.\nAbstract: The Mild Behavioral Impairment Checklist (MBI-C) captures neuropsychiatric symptoms in individuals at risk of dementia. In this study, we examined MBI-C scores in autosomal dominant Alzheimer's disease (ADAD). We included 83 cognitively unimpaired presenilin-1 E280A mutation carriers and 114 non-carriers with MBI-C, obfjective cognition, and subjective cognitive decline (SCD) assessments. Study sub-samples underwent neuroimaging to assess Alzheimer's disease (AD) pathology and neurodegeneration. MBI-C total scores were greater in carriers than non-carriers (r rb = 0.19 [95% confidence interval (CI) 0.05, 0.31], P = 0.009), driven by impulse dyscontrol symptoms. Elevated MBI-C scores were associated with higher study partner-reported SCD scores (β = 0.28 [95% CI 0.07, 0.050], P = 0.008) and with greater neocortical amyloid beta (β = 0.46 [95% CI 0.17, 0.075], P = 0.003) among carriers. Our study reveals that mild behavioral impairment symptoms may emerge before cognitive decline in ADAD and supports the MBI-C as a tool for detecting early behavioral changes linked to AD pathology and identifying at-risk individuals for clinical trials and early intervention.","42444751":"ID: 42444751\nTitle: Heterogeneous responses to memantine in Alzheimer's disease: A precision medicine approach using iPSC models.\nAbstract: Alzheimer's disease (AD) is a complex neurodegenerative disorder characterized by progressive cognitive and functional decline. Memantine, a commonly prescribed N-methyl-D-aspartate receptor antagonist, appears to slightly delay symptom progression in moderate or advanced stages of AD. Clinical response is highly variable across patients with some benefiting but others not. Induced pluripotent stem cell (iPSC)-derived neurons can provide a donor-dependent model to predict the therapeutic efficacy of memantine. We generated iPSC-derived cortical neurons from 19 individuals (12 AD and 7 cognitively unimpaired [CU]). Assays for calcium influx and oxidative stress were developed and optimized for neurons. Memantine was tested under different treatment conditions. Neurons were exposed to glutamate/glycine to induce calcium influx and menadione to generate oxidative stress. Memantine treatment was applied either acutely (1 hour) or as a 24-hour pre-treatment to evaluate its neuroprotective effects. Peripheral blood mononuclear cell-derived iPSCs were successfully differentiated into functional neurons, exhibiting comparable electrophysiological properties between AD and CU lines. Calcium influx assays revealed a heterogeneous response among AD and CU neurons, with AD neurons generally displaying higher baseline fluorescence. Memantine treatment for 24 hours significantly reduced calcium influx, with a -9.85% average reduction and a range of -0.39% to -39%. Similarly, reactive oxygen species assays showed menadione-induced oxidative stress was attenuated by 24-hour memantine pre-treatment for a mean -26.05% reduction and a range of -4.23% to -72.21%. The observed variability indicates differential susceptibility to excitotoxicity reduction and or oxidative stress mitigation across lines. This exploratory study establishes a robust in vitro platform to test memantine efficacy using iPSC-derived neurons to model calcium dysregulation and oxidative stress in AD. The observed variability in response highlights the importance of personalized approaches in AD treatment, emphasizing the potential for iPSC-based platforms in precision medicine.","42444752":"ID: 42444752\nTitle: Anti-amyloid nanobody-Fc fusion protein drives potent amyloid clearance through microglial recruitment.\nAbstract: Anti-amyloid beta (Aβ) monoclonal antibodies are effective at lowering amyloid in Alzheimer's disease (AD). However, whether Fc-mediated effector function is absolutely required for efficacy is not completely understood. This is important for optimizing therapeutic efficacy and mitigating side effects such as amyloid-related imaging abnormalities (ARIA). Antibodies lacking Fc effector function, like single-domain antibodies (nanobodies), offer a unique tool to dissect these mechanisms, as their small size facilitates blood-brain barrier (BBB) penetration and allows Fc-mediated functions to be studied independently. We immunized a llama with Aβ aggregates and constructed a phage display library to screen for aggregate-specific nanobodies. Lead candidates were characterized by epitope mapping and binding affinity to amyloid plaques in both murine and human AD brain tissues. We further assessed their BBB permeability and evaluated their efficacy in clearing pre-existing plaques in amyloid precursor protein (APP)/presenilin 1 (PS1) mice. We identified two lead nanobodies, 3A11 and 2D10, that bind distinct epitopes and specifically bind Aβ plaques in murine and human AD brain tissues. Following systemic administration, the monovalent, unmodified (Fc-less) 2D10 nanobody, but not 3A11, successfully crossed the BBB and engaged amyloid plaques in APP/PS1 mice. However, despite robust target engagement, the Fc-less 2D10 failed to recruit microglia or reduce plaque burden. In contrast, an engineered 2D10-Fc fusion antibody potently cleared amyloid plaques, achieving a reduction in pathology comparable to aducanumab treatment. This efficacy was directly correlated with Fc-mediated microglial recruitment and activation, demonstrating that the Fc domain is essential for phagocytic plaque removal. Our findings demonstrate that Fc effector function is indispensable for microglial-mediated amyloid clearance in vivo. By clarifying this fundamental mechanism, this study provides a framework for the rational design of next-generation immunotherapies. Furthermore, 2D10-Fc represents a promising therapeutic candidate, combining the high-affinity targeting of nanobodies with the effector power necessary for robust plaque clearance.","42444987":"ID: 42444987\nTitle: The amino acid substitutions A30W, K28A, and M35C alter amyloid-β peptide toxicity in cell culture and in an in vivo model of amyloidosis in Caenorhabditis elegans.\nAbstract: The buildup of toxic aggregates formed by the amyloid-β peptide 1-42 (Aβ42) is a central process in Alzheimer's disease (AD) pathology. The peptide's self-assembly and toxicity are highly dependent on its primary amino acid sequence and can be altered by modifying key residues. Specifically, the single amino acid substitutions A30W, K28A, and M35C can reduce the aggregation and toxicity of the Aβ42 peptide. In this study, we further evaluated the effects of these mutations in a C6 rat glioma cell line and in the Caenorhabditis elegans strains CL2006 and CL4176, which express muscular Aβ42 as an in vivo model. Our results showed that the A30W, K28A, and M35C substitutions reduce apoptosis induction in cell culture, in contrast to the WT Aβ42 peptide. In C. elegans, the three variants extended the lifespan of CL2006 worms by reducing fibrillar aggregates or altering aging, whereas the M35C peptide delayed the paralysis of CL4176 worms. Additionally, the substitutions altered oxidative stress and autophagy in control worms. Taken together, these results suggest that the A30W, K28A, and M35C substitutions reduce Aβ42 toxicity in cell culture and in C. elegans and could protect the nematode against Aβ42 toxicity.","42445022":"ID: 42445022\nTitle: High-Throughput CETSA Identifies Small Molecule Modulators of ILT3 (LILRB4) with Functional Activity in Human iPSC-Derived Microglia for Alzheimer's Disease.\nAbstract: Immune inhibitory signaling in microglia contributes to impaired amyloid-β (Aβ) clearance and neuroinflammation in Alzheimer's disease (AD), yet small molecule modulators targeting these pathways remain largely unexplored. Here, we report the development of a high-throughput cellular thermal shift assay (HT-CETSA) platform for identification of small molecule binders targeting the inhibitory immune receptor ILT3 (LILRB4). Screening of ∼40 000 compounds yielded multiple validated hits, including IB15C, a submicromolar ILT3 binder identified through preliminary structure-activity relationship optimization. Orthogonal validation by microscale thermophoresis, surface plasmon resonance, docking, and site-directed mutagenesis confirmed direct and target-specific ILT3 engagement. Functionally, IB15C disrupted the ILT3-ApoE interaction and restored microglial activity in human iPSC-derived microglia, reducing SHP1/2 and NF-κB signaling, suppressing IL-1β secretion, and enhancing Aβ uptake. IB15C also demonstrated favorable in vitro pharmacokinetic and safety properties, supporting further development of ILT3-targeted neuroimmune therapeutics.","42445281":"ID: 42445281\nTitle: Advances in research on pharmacological mechanisms of anatabine: from nicotinic modulation to multitarget therapeutic potential.\nAbstract: Anatabine, a characteristic minor alkaloid derived from tobacco byproducts, exhibits unique structural analogy to nicotine but possesses a superior safety profile and lower addictive liability, rendering it a promising natural multi-target therapeutic candidate. Accumulating preclinical evidence has demonstrated that anatabine exerts neuroprotective, anti-inflammatory, and antioxidant effects mainly through modulating α7/α4β2 nicotinic acetylcholine receptors, suppressing NF-κB/STAT3 inflammatory signaling, and activating the Nrf2-mediated antioxidant pathway. It effectively ameliorates typical pathological alterations, including β-amyloid deposition, tau hyperphosphorylation, and microglial overactivation, thereby improving cognitive and behavioral deficits in neurodegenerative disease models. Additionally, anatabine displays broad pharmacological potentials in chronic inflammation, autoimmune thyroiditis, asthma, and hypertension. Differing from previous reviews that merely focused on single receptor regulation, the present work systematically summarizes the multi-target pharmacological characteristics of anatabine, comprehensively collates its preclinical efficacy across multiple disease categories, and highlights its advantages over nicotine in safety and addiction risk. Furthermore, we analyze the current limitations, druggability optimization challenges, and clinical translation prospects, and propose sustainable strategies for high-value utilization of tobacco byproducts. This review provides an updated and systematic theoretical basis for further mechanism exploration and therapeutic development of anatabine.","42445345":"ID: 42445345\nTitle: Changes in cortical plasticity induced by paired associative stimulation in people with mild cognitive impairment and Alzheimer's disease: a systematic review and meta-analysis.\nAbstract: Paired associative stimulation (PAS) is a non-invasive neuromodulation paradigm capable of inducing long-term potentiation (LTP)- or long-term depression (LTD)-like plasticity. It has been used to probe neuroplasticity and corticospinal excitability alterations in Alzheimer's disease (AD) and mild cognitive impairment (MCI). However, existing studies report inconsistent directions and magnitudes of PAS-induced plasticity changes across the AD continuum. We searched PubMed, Web of Science, Embase, and the Cochrane Library from database inception to December 2025. Eligible studies were case-control studies and randomized controlled trials (RCTs) that assessed PAS-induced cortical plasticity in individuals with AD or MCI, with healthy older adults as controls. Study quality was evaluated using the Newcastle-Ottawa Scale (NOS) for non-randomized studies and the Cochrane Risk of Bias tool (RoB 2) for RCTs. This review was registered in PROSPERO (CRD420251178441). Five studies met the inclusion criteria. Four studies quantified motor cortical plasticity using changes in motor-evoked potential (MEP) amplitude (total N = 135; 64 MCI/AD and 71 controls). The pooled analysis showed no significant difference in PAS-induced MEP changes between participants with MCI/AD and healthy controls [mean difference (MD) = 0.06, 95% CI (-0.05, 0.17), p = 0.32]. This pooled estimate was restricted to MEP-based outcomes and should be interpreted as an exploratory synthesis of motor-system readouts rather than definitive evidence of preserved cortical plasticity in MCI or AD. The remaining RCT, which assessed dorsolateral prefrontal cortex (DLPFC) plasticity using a repetitive PAS (rPAS) intervention without MEP outcomes, also found no significant improvement in prefrontal plasticity relative to control stimulation. Based on the currently available MEP-based evidence, PAS-induced motor-system plasticity findings in individuals with MCI or AD remain inconclusive. Given the limited number of studies and heterogeneity in experimental designs, the pooled negative results should not be interpreted as evidence that cortical plasticity is preserved. Corticospinal hyperexcitability and network-level PAS findings should be regarded as preliminary, hypothesis-generating observations requiring validation in larger, longitudinal, and biomarker-characterized cohorts.","42445718":"ID: 42445718\nTitle: Central neural circuits and their associated mechanisms of inter-organ crosstalk.\nAbstract: The central nervous system (CNS), which comprises the brain and spinal cord, serves as the core regulatory hub for maintaining homeostasis and coordinating diverse physiological functions. These functions include interoception, cognition, and social behavior. The intricate architecture and extensive connectivity of the CNS enable integration of multi-system responses, thereby ensuring bodily stability and adaptability. The CNS exerts profound regulatory influences on fundamental life-sustaining processes and higher-order cognitive and social functions. This is mediated by distinct neural circuits and molecular mechanisms. CNS dysfunction is strongly associated with the pathogenesis of neurological disorders (Alzheimer's disease, Parkinson's disease, stroke and epilepsy), metabolic diseases (obesity and diabetes), and cardiovascular conditions (hypertension and atherosclerosis). Given the pivotal role of the CNS in both physiological regulation and disease progression, a comprehensive understanding of CNS mechanisms is critical for identifying therapeutic targets. This review systematically examines the regulatory functions of the CNS in physiology and disease. Moreover, this review analyzes the underlying molecular and circuit-level mechanisms, and discusses potential therapeutic strategies. By elucidating the systemic interactions of the CNS, this study aims to highlight its potential as a target for innovative interventions in disease prevention, diagnosis, and treatment.","42445988":"ID: 42445988\nTitle: CSF1R inhibition exacerbates gamma oscillation disruption and induces network hyperexcitability in APP/PS1 mice.\nAbstract: Alzheimer's Disease is the most common neurodegenerative disease worldwide, but significant gaps in pathophysiological understanding have hampered development of disease-modifying therapies. In Alzheimer's disease, neurophysiological function is impaired, with gamma frequency oscillations - thought to be essential for higher-order cognitive processes - disrupted in both patients and animal models. However, the mechanisms driving these disruptions are unclear and, in particular, the role of neuroinflammation in these changes is poorly understood. In this study, we investigated neuronal network dynamics in acute brain slices from APP/PS1 transgenic mice. Gamma frequency oscillations had significantly reduced amplitude in APP/PS1 brain slices at 9-11 months, accompanied by an increase in beta frequency power and heightened epileptiform activity. This is suggestive of a slowing in neuronal oscillations, considered a neurophysiological hallmark of Alzheimer's disease. Immunohistochemical analysis revealed a reduction in parvalbumin- and somatostatin-positive inhibitory interneuron populations. Treatment with gabazine demonstrated increased network sensitivity to GABAA receptor antagonism, further indicating compromised inhibitory control in APP/PS1. As these altered oscillatory dynamics correlated with microglial reactivity, we hypothesised a causal role for microglia. Administration of the CSF1R inhibitor GW2580 reduced microglial proliferation, attenuated development of the disease-associated microglial phenotype and partially rescued synaptic loss; but, had no significant impact on amyloid plaque burden or cognitive deficits. Unexpectedly, GW2580 treatment exacerbated neuronal network hyperactivity and the incidence and complexity of epileptiform activity. Microglia in GW2580-treated mice showed reduced CD68 expression and decreased engulfment of synaptic elements, potentially facilitating the persistence of hyperexcitable synapses. These findings support a role of microglia in regulating neuronal network homeostasis and caution against indiscriminate suppression of microglial activity in Alzheimer's disease. Therapeutic strategies targeting microglia must account for their homeostatic functions to avoid adverse effects on neuronal network stability.","42446006":"ID: 42446006\nTitle: Algorithmic Choreography: Redefining Human and Non-Human Relations in Digital Health.\nAbstract: This article contributes to the growing debate on algorithms in digital health, which has expanded alongside the integration of algorithmic technologies into diverse healthcare practices and contexts. Although much of the existing literature adopts a deterministic perspective, focusing on the impact of algorithms on society, we propose a different approach. Drawing on the concept of algorithmic choreography, we show how humans and algorithmic technologies \"gear together\" in shared performances. Based on an ethnographic study in a nursing home for people with dementia, we examine a telemonitoring algorithmic system designed to prevent adverse events and how it enters into relations with the humans inhabiting this healthcare organization. The system gives rise to two distinct choreographies: night monitoring, in which staff use it for real-time observation of residents' movements and quantified decision-making, where algorithmically generated indexes support longitudinal assessments of residents' health status. We argue that in both choreographies, humans remain central rather than passive recipients of innovation. Care professionals give or withhold agency from algorithms, sustain their functioning and engage in collective improvisations through which human-nonhuman interactions are continually reshaped.","42446082":"ID: 42446082\nTitle: The economic burden of dementia in Europe: COIN-Eu dementia.\nAbstract: BackgroundDementia, with Alzheimer's disease as its most common underlying cause, is a major contributor to disability, dependency, and death, imposing significant societal and economic burdens across Europe. Despite its growing prevalence, cross-country cost estimates remain scarce and highly heterogeneous, limiting comparability.ObjectiveTo estimate country-level societal costs of dementia in Europe and to derive aggregate European cost estimates, including direct costs, indirect costs (productivity losses), and informal care costs.MethodsA standardized review of dementia cost assessments conducted in Europe was performed. Heterogeneous cost-estimation approaches were harmonized using pooling and health-economic imputation techniques to address data gaps and generate country-level estimates. All cost estimates were converted to 2019 euros using Consumer Price Indices and Purchasing Power Parities (PPP). Informal care costs were analyzed separately to reflect their complexity and substantial contribution to total costs.ResultsForty-five studies were identified. Annual societal costs of dementia in high-income European countries totaled €221.4 billion (€PPP, 2019; €25,218 per patient) for 8.8 million people with dementia. Informal care and direct costs accounted for 58% and 42% of total costs, respectively. Indirect costs contributed minimally to total costs. Substantial variation in per patient costs across countries was observed.ConclusionsDementia care imposes substantial societal burdens, largely driven by informal care. Owing to data availability, estimates were limited to high-income European countries. Future research should focus on standardizing cost assessment methods, improving informal care valuation, expanding evidence from low- and middle-income countries, and evaluating the financial impact of emerging treatments and prevention strategies.","42446245":"ID: 42446245\nTitle: Speech-In-Noise Perception in Alzheimer's Disease and Primary Progressive Aphasia.\nAbstract: Understanding speech despite background noise is essential for everyday communication, but makes heavy neural processing demands. It is therefore potentially vulnerable to neurodegenerative diseases, particularly those led by communication deficits (primary progressive aphasia). However, how speech-in-noise perception is affected in these diseases is poorly understood. Here we addressed this in 59 patients representing typical Alzheimer's disease and canonical logopenic, nonfluent/agrammatic and semantic variant syndromes of primary progressive aphasia, compared with 24 cognitively-well, older controls. We administered a digit triplet test of speech-in-noise perception based on the task used in the UK Biobank study, alongside pure tone audiometry and a general neuropsychological assessment. Voxel-based morphometry of patients' brain MRI scans was used to identify structural neuroanatomical associations of speech-in-noise perception. After adjusting for age, peripheral hearing and general cognitive function, the Alzheimer's, logopenic and nonfluent primary progressive aphasia groups performed significantly worse on speech-in-noise perception than controls. The nonfluent primary progressive aphasia and Alzheimer groups additionally had significantly worse peripheral hearing function than controls. Speech-in-noise perceptual performance correlated with grey matter atrophy in the right supramarginal gyrus. Profiles of central (brain) and peripheral hearing impairment stratify major dementias, with implications for diagnosis and development of interventions to improve real-world communication in people living with dementia.","42446473":"ID: 42446473\nTitle: Multilayer Proteome and Metabolome-Based Validation Uncovers Combined Regulatory Roles and Predictive Values of 6 RNA Modifications and Cellular Senescence in Alzheimer's Disease.\nAbstract: Existing studies have revealed that RNA modification regulators and cellular senescence can affect the Alzheimer's disease (AD) process. This study investigated the synergistic mechanism in the brains of AD. Based on brain tissue proteomics of patients with AD, we screened out the subtypes of patients that are coordinately regulated by cellular senescence-related proteins and RNA modification regulators. Transcriptome datasets were used to validate and evaluate 20 hub proteins identified using 100 integrated machine learning algorithms. Finally, protein and metabolic data were employed to explore the characteristics of metabolic subtypes and pathways in AD progression. The diagnostic model had good diagnostic performance, as revealed by the average area under the receiver operating characteristic curve (AUC) = 0.885 of the internal datasets and the average AUC = 0.89 of transcriptome datasets. Risk score can be used to assess disease progression and the corresponding changes in metabolic characteristics. Finally, metabolic analysis indicates significant abnormalities in amino acid and lipid metabolism during the progression of AD. We revealed the potential role of RNA modification regulators and cellular senescence-related proteins in AD pathogenesis and related diagnostic markers through proteomic analysis and machine learning-based methods.","42446515":"ID: 42446515\nTitle: Understanding the cellular architecture of Huntington's disease.\nAbstract: A new diffusion MRI approach offers a glimpse of the anomalies of cellular architecture underlying basal ganglia degeneration in Huntington's disease.","42446696":"ID: 42446696\nTitle: 4-methylbenzyl 5-arylthiophene-2-carboxylates as Multitarget Directed Ligands Scaffolds (MTDLs): Synthesis, in-silico docking studies, and evaluation of dual selective enzymatic inhibition (AChE & MAO-B).\nAbstract: Single-target ligands have insufficient effectiveness in treating Alzheimer's disease (AD), leading to the development of new pharmacological strategies, particularly multi-target-directed ligands (MTDLs) that tackle the multifactorial nature of the impairment. Among these, dual inhibition of acetylcholinesterase (AChE) and monoamine oxidase B (MAO-B) represents a promising approach for enhancing therapeutic outcomes. Here, analogs of 4-methylbenzyl 5-arylthiophene-2-carboxylates (5a-5h) were identified as dual inhibitors of AChE and MAO-B. In vitro evaluations demonstrated that 5a-5d exhibited the most promising inhibition potential towards targeted enzymes (AChE and MAO-B), having IC50 values 0.72 ± 0.01 µM to 1.69 ± 0.04 µM for AChE and 0.19 ± 0.03 µM to 2.69 ± 0.10 µM for MAO-B.

These results underscore the promise of these dual inhibitors in tackling the complex pathology of AD.","42446728":"ID: 42446728\nTitle: Protein kinases as therapeutic targets in Alzheimer's disease: challenges, insights, and new frontiers.\nAbstract: Alzheimer's disease (AD) remains the leading cause of dementia worldwide, imposing an enormous and growing societal burden with more than 55 million people affected globally. Despite decades of intensive investigation, existing therapeutic options provide only modest symptomatic relief and fail to prevent or slow disease progression, emphasizing the critical need for interventions that target the fundamental molecular mechanisms of neurodegeneration. Pathologically, Alzheimer's disease is characterized by extracellular accumulation of amyloid-β plaques, intracellular neurofibrillary tangles formed by hyperphosphorylated tau, profound synaptic loss, chronic neuroinflammation, and extensive neuronal degeneration. Although amyloid-focused strategies have long dominated drug development, their limited clinical benefit and safety liabilities highlight the multifactorial nature of AD and the need to move beyond amyloid-centric paradigms. Protein kinases have emerged as key integrators of multiple pathogenic processes in AD, governing tau phosphorylation, amyloid precursor protein processing, synaptic signaling, and neuroimmune responses. Aberrant kinase signaling drives tau pathology and propagation, promotes amyloidogenic pathways, disrupts synaptic function, and perpetuates inflammatory cascades. While extensive work on kinases such as GSK-3β, CDK5, JNKs, and CSF1R has firmly established the relevance of kinase dysregulation in AD, no kinase-directed therapy has yet translated into clinical success. This review highlights emerging kinase targets beyond these classical pathways, including Fyn, Casein Kinase 1 Delta (CK1δ), Tau-Tubulin Kinase 1 (TTBK1), and Dual Leucine Zipper Kinase (DLK), which are supported by mechanistic insights and compelling preclinical evidence. Continued advances in brain-penetrant, isoform-selective, and mechanism-driven kinase inhibitor design may enable the development of next-generation disease-modifying therapies for Alzheimer's disease.","42446837":"ID: 42446837\nTitle: Molecular Regulation of Pyroptosis in Alzheimer's Disease: Linking Neuroinflammation, Cell Death, and Therapeutic Targeting.\nAbstract: Alzheimer's disease (AD) is a progressive neurodegenerative disorder characterized by profound cognitive decline, wherein chronic neuroinflammation plays a pivotal pathogenic role. Central to this inflammatory milieu is pyroptosis, a highly inflammatory form of programmed lytic cell death mediated by gasdermin proteins. This comprehensive review provides an in-depth synthesis of the cellular and molecular mechanisms underlying pyroptosis in AD. We detail the distinct roles of microglia as primary initiators responding to amyloid-beta (Aβ) and tau aggregates, alongside the specific vulnerabilities of neurons facing oxidative stress, astrocytes impacting metabolic support, and endothelial cells whose pyroptotic death contributes directly to blood-brain barrier disruption. At the molecular level, the priming and activation of the NLRP3 and NLRP1 inflammasomes by diverse triggers, including classical markers like Aβ, environmental neurotoxicants and metabolic stressors, converge on caspase-1 and caspase-8 activation. This cascade culminates in gasdermin D (GSDMD) and gasdermin E (GSDME) pore formation, leading to cellular lysis and the massive release of pro-inflammatory cytokines such as IL-1β and IL-18. Furthermore, this paper explores the emerging and critical concept of PANoptosis, highlighting the intricate crosstalk between pyroptosis, apoptosis, and necroptosis within PANoptosome complexes triggered by mitochondrial dysfunction. We evaluate current and prospective therapeutic strategies, ranging from multi-target natural and traditional herbal remedies to advanced nanomedicine, synthetic small molecules, and epigenetic gene therapies. By integrating insights from blood-based pyroptosis-associated molecular signatures and advanced targeted drug delivery systems, we emphasize the critical need for personalized, multi-targeted approaches to successfully harness pyroptosis modulation in the clinical management and treatment of AD.","42446869":"ID: 42446869\nTitle: Single-cell analysis of Powassan virus-infected brains reveals age-dependent neuroinflammatory crosstalk and progressive Alzheimer's-like APP/Aβ accumulation.\nAbstract: Powassan virus (POWV) causes lethal encephalitis in the elderly and long-term neurological sequelae in survivors. Mirroring human disease, POWV strain LI9 directs age-dependent lethality in C57BL/6 (B6) mice, resulting in spongiform encephalitis, gliosis, and inflammatory cytokine/chemokine responses in the CNS. However, the mechanisms underlying age-dependent lethality and persistent neurodegenerative disease in POWV survivors remain to be resolved. Here, we analyzed cellular CNS responses to POWV LI9 infection in young (10-week-old) and aged (50-week-old) mice using single-cell RNA sequencing. Infection of young mice resulted in inflammatory CNS infiltrates (NK, CD4/CD8 T cells, and monocytes) and interferon responses that coincide with peak viral burden. In contrast, the CNS of aged infected mice instead featured upregulated astrocyte and neuronal genes associated with neurodegenerative and Alzheimer's disease pathways and the transition of homeostatic microglia to a Trem2-ApoE-linked disease-associated microglial transcriptional state. Histological analysis revealed that amyloid precursor protein (APP)/amyloid-β (Aβ) accumulated in the CNS following POWV infection and that POWV envelope protein and APP/Aβ were selectively localized within layers L5/L6 of the cerebral cortex. POWV kinetically increased perinuclear APP/Aβ accumulation during acute infection and was highly expressed in the CNS of POWV survivors. Our findings reveal that POWV triggers glial cell responses and a neurodegenerative disease-associated microglia program of Alzheimer's-like APP/Aβ accumulation in mice, which is consistent with long-term neurological sequelae in human POWV survivors.IMPORTANCEPowassan virus (POWV) causes lethal encephalitis and long-term cognitive deficits in survivors. Using an age-dependent murine model, we reveal that POWV-infected young mice direct robust CNS inflammatory infiltrates associated with viral clearance, whereas aged mice exhibit impaired immune responses and a shift from homeostatic to neurodegenerative glial cell states. POWV prompted the induction of disease-associated microglia (DAM) and Trem2-ApoE axis transcriptional responses that are hallmarks of APP/amyloid-β (Aβ) accumulation in Alzheimer's disease (AD). Remarkably, POWV induced progressive APP/Aβ accumulation in young and aged mice that persisted in survivors after viral clearance. This suggests that POWV induces an APP/Aβ neurodegenerative process and provides a potential cause of long-term neurological sequelae observed in human POWV survivors. Our data suggest that POWV initiates or exacerbates AD-like neuropathology and further rationalizes investigating the role of APP/Aβ responses in other encephalitic viruses.","42446988":"ID: 42446988\nTitle: 3D nanoscale imaging of amyloid-β oligomer interactions with extracellular vesicles by cryo-ET.\nAbstract: Central to Alzheimer's disease pathology are prefibrillar oligomer assemblies of amyloid-β (Aβ) peptide. A widely discussed hypothesis proposes that amyloid-β oligomers insert into neuronal lipid membranes, disrupting their integrity and causing a loss of cellular homeostasis in Alzheimer's disease. This membrane disruption is believed to be a major source of Aβ-induced neurotoxicity. Cryo electron tomography (cryo-ET) has facilitated 3D nanoscale imaging of Aβ-membrane interactions under near-native conditions. Analyses of small extracellular vesicles (sEVs) reveals that Aβ oligomers including annular and curvilinear extended oligomers (CLEOs) exhibit extensive binding to cell-derived lipid membranes, including insertion into and carpeting of the lipid bilayer. Notably, these oligomeric assemblies were also internalized and concentrated within the cell-derived exosomes and other small sEVs. Enrichment of Aβ oligomers within the vesicles typically ranged between 5 to 20 times the external Aβ levels depending on the vesicle size and curvature. In contrast, monomeric and fibrillar forms of Aβ displayed minimal membrane interaction. Once internalized CLEOs appear to be trapped in an oligomeric form and do not readily go on to form fibrils. Studies with vesicles of brain lipid extract indicate the Aβ internalization does not require the presence of a membrane protein. Our in vitro studies underscore the membrane-disruptive capacity of oligomeric Aβ species and suggest a role of sEVs in concentrating toxic Aβ oligomers and transporting oligomers across the brain interstitium.","42446992":"ID: 42446992\nTitle: Repurposing trazodone for Alzheimer's disease to modulate soluble ST2 levels and alleviate Alzheimer's pathology.\nAbstract: Alzheimer's disease (AD) is a multifactorial disorder involving various pathological mechanisms, such as amyloidosis, immune dysfunctions, and synaptic impairments, which are important therapeutic targets. Repurposing drugs to target these mechanisms offers a promising approach to reduce the costs and duration of drug development. Genetic studies underscore the critical role of microglial clearance of amyloid-beta (Aβ) in AD pathogenesis. Specifically, soluble ST2 (sST2)-one of the two major isoforms of the ST2 protein encoded by the IL1RL1 (interleukin-1 receptor-like 1) gene-acts as a decoy receptor isoform that interferes with IL-33/ST2 signaling and has been identified as a disease-modifying factor that impairs microglial Aβ clearance functions. In this study, we investigated drug repurposing opportunities to modulate sST2 levels and alleviate AD pathologies. Unbiased screening of commonly used medications in AD patients, followed by validation in model systems, identified trazodone-an antidepressant used to treat major depressive disorder-as a leading negative regulator of sST2. Trazodone primarily suppresses sST2 expression through its antagonistic effects on adrenergic signaling. In the APP/PS1 transgenic mouse model of AD, trazodone treatment enhanced microglial interaction with Aβ and alleviated Aβ pathology. Furthermore, trazodone reduced neurodegeneration and rescued synaptic deficits in APP/PS1 mice. Comprehensive molecular profiling of APP/PS1 mouse brains showed that trazodone restored the expression of synaptic proteins critical for synaptic integrity and plasticity. Overall, these findings demonstrate that trazodone is a promising repurposing candidate for AD that targets underlying immune dysfunctions and synaptic impairment.","42447315":"ID: 42447315\nTitle: Lost in Scheduling? A Reliable Tool for Detecting Subtle Cognitive Decline in Mild Cognitive Impairment and Mild Alzheimer's Disease.\nAbstract: Neurodegenerative diseases, notably Alzheimer's disease (AD), present a significant public health challenge. This study aims to evaluate the effectiveness of the Ecological Assessment Battery for Numbers (EABN) in detecting subtle cognitive decline in mild cognitive impairment (MCI) and mild AD, focusing on everyday life mathematical situations. This cross-sectional study involved 66 participants (21 mild AD, 23 MCI, and 22 controls). Clinical assessments included the Mini-Mental State Examination (MMSE), the EABN, and the Numerical Activities of Daily Living questionnaire. Statistical analyses utilized nonparametric tests, Spearman rank correlation, and receiver operating characteristic curve analyses. The EABN demonstrated an area under the curve (AUC) of 0.83 (95% confidence interval [0.73, 0.92]) in distinguishing patients and controls. Patients with pathologically high EABN scores were significantly older, and a positive correlation was observed between EABN and MMSE scores (r = .30; p = .04). The Appointment subtest within EABN emerged as the most discriminative (AUC = 0.86). Among MCI patients with pathological EABN scores, 70% progressed to AD or amyloid angiopathy. This study reveals early manifestation of mathematical cognition impairments in cognitive decline, even before patient-reported complaints. The EABN, a practical tool for ecological assessment, could aid in early diagnosis and guide interventions. Integrating mathematical cognition assessment into routine care aligns with recommendations for cognitive rehabilitation in MCI patients, potentially preventing autonomy loss. These findings underscore the significance of a comprehensive approach to patient management, incorporating ecological assessments for nuanced diagnostics and early intervention in neurodegenerative diseases.","42447420":"ID: 42447420\nTitle: Orexin, Sleep, and Cognition in Alzheimer Disease: Non-REM Oscillatory Activity and Neural Resilience.\nAbstract: Sleep-wake dysregulation and elevated CSF orexin have been implicated in Alzheimer disease (AD). Sleep spindles (SPs) and slow oscillations (SOs) are linked to cognition and neurodegeneration; however, their relationship with CSF orexin concentrations in symptomatic AD has not been characterized. We investigated whether nonrapid eye movement (NREM) SP-SO activity is associated with CSF orexin and whether these oscillatory features moderate associations between orexin, cognition, neuropsychiatric symptom severity, and AD biomarkers. This prospective observational cohort study was conducted at a tertiary memory clinic in Lleida, Spain. Individuals aged ≥60 years with biomarker-confirmed mild-to-moderate AD (National Institute on Aging-Alzheimer's Association criteria) underwent overnight polysomnography and morning CSF sampling. SP and SO were detected using validated automated algorithms with independent verification and visual quality control. CSF was assayed for orexin-A, amyloid-β42 (Aβ42), phosphorylated tau181 (pTau181), total tau, and YKL-40. Cognitive performance Alzheimer's Disease Assessment Scale-Cognitive Subscale ([ADAS-Cog], Mini-Mental State Examination (MMSE), California verbal learning test, ROCF) and neuropsychiatric symptoms (NPI) were assessed longitudinally over 36 months. Associations were examined using generalized linear models with robust estimators adjusted for age, sex, Aβ42, and apnea-hypopnea index. Multiple comparisons were controlled using false discovery rate correction. Interaction terms assessed moderation effects. Sixty participants (30 women; mean age 74.7 years) were included. Longer SO duration and higher SP density and power were associated with lower CSF orexin concentrations (SP density: β = -187.37 pg/mL, 95% CI -344.93 to -29.80). Orexin was not associated with global sleep continuity metrics. Higher CSF orexin concentrations were associated with worse global cognition (ADAS-Cog: β = 0.014, 95% CI 0.003-0.024; MMSE: β = -0.01, 95% CI -0.011 to -0.004) and greater neuropsychiatric symptom severity (NPI at: β = 0.03, 95% CI 0.011-0.041). Higher orexin was also associated with higher pTau181 (β = 0.11, 95% CI 0.04-0.19), total tau, and YKL-40 (β = 0.37, 95% CI 0.17-0.57). Significant orexin × SP-SO interactions were observed, such that greater oscillatory activity attenuated the adverse associations between orexin and cognitive outcomes, independent of Aβ42 and tau. In biomarker-confirmed AD, NREM SP and SO activity are associated with CSF orexin concentrations and moderate associations between orexin and longitudinal cognitive and neuropsychiatric outcomes. Limitations include the observational design and absence of a comparator group, precluding causal inference and limiting contextualization relative to normal aging. NREM oscillatory metrics and orexin concentrations may represent complementary physiologic markers for disease monitoring and therapeutic targeting.

In this work, we developed a highly sensitive electrochemiluminescence (ECL) aptasensor for detecting a key AD biomarker, Tau protein. An all-inorganic perovskite CsPbBr3 nanocrystals (NCs) were used as ECL emitters and were encapsulated with polyvinylpyrrolidone (PVP) to improve the stability of CsPbBr3 NCs in aqueous solution. Moreover, -PVP encapsulation significantly enhanced the ECL response via coordination between the lone-pair electrons of oxygen atoms and Pb2+. The obtained CsPbBr3@PVP composite was further functionalized with gold nanoparticles, which served as anchoring sites for the immobilization of a Tau-specific aptamer. The sensing mechanism relies on the specific recognition between the surface-bound aptamer and the Tau protein. The formation of the aptamer-target complex impeded the ECL reaction efficiency of the system, resulting in an \"off\" ECL sensing response. This strategy enables ultrasensitive detection of Tau protein with a wide linear range from 10 fg/mL to 108 fg/mL and a detection limit as low as 0.80 fg/mL. The aptasensor also demonstrated satisfactory recoveries of 97.2% to 108.6% in mouse cerebrospinal fluid with relative standard deviations below 6.5%, indicating its promising potential for early diagnosis of AD."},"globalTags":{"alzheimer's disease":23,"aptamer":1,"electrochemiluminescence":1,"perovskite":1,"tau protein":1,"alzheimer disease":31,"animals":27,"drug
