The statins remain the foundation of lipid management because they lower low-density lipoprotein cholesterol (LDL-C) and prevent cardiovascular events, and guidelines recommend stepwise intensification, often with ezetimibe first, when targets are not met or when intolerance limits dosing. This review introduces a mechanism-first, phenotype-guided framework that links add-on therapies to the dominant driver of residual risk, LDL-C, triglyceride-rich lipoproteins, elevated lipoprotein(a), or inherited dyslipidemia while integrating trial evidence with clinical practicality. Proprotein convertase subtilisin/kexin type 9 (PCSK9) monoclonal antibodies remain the best-validated add-on for very high-risk patients. FOURIER and ODYSSEY OUTCOMES demonstrated event reduction with evolocumab or alirocumab on background statin therapy. For patients who cannot tolerate adequate statin doses, bempedoic acid provides liver-selective inhibition of adenosine triphosphate (ATP)-citrate lyase, and CLEAR Outcomes showed fewer major cardiovascular events in statin-intolerant populations. Inclisiran extends PCSK9 pathway suppression through hepatic small interfering RNA (siRNA) and enables durable LDL-C reduction with twice-yearly maintenance dosing, offering an adherence-oriented alternative while outcomes data mature. Angiopoietin-like protein 3 (ANGPTL3)-directed therapies (evinacumab and investigational RNAi agents such as zodasiran) lower atherogenic lipoproteins through largely LDL receptor independent biology. They expand options for refractory disease, including homozygous familial hypercholesterolemia. Apolipoprotein C-III (ApoC-III) inhibitors (olezarsen and plozasiran) drive large triglyceride reductions that can be decisive in severe hypertriglyceridemia and pancreatitis-prone syndromes. Next-generation cholesteryl ester transfer protein (CETP) inhibition (notably obicetrapib) has re-emerged as an oral strategy with substantial lipid effects as outcomes programs progress. High-dose eicosapentaenoic acid (EPA) (icosapent ethyl) has the clearest triglyceride-focused outcomes signal; REDUCE-IT showed significant ischemic event reduction in statin-treated patients with persistent hypertriglyceridemia.

Cholesteryl ester transfer protein (CETP) inhibition reduces low density lipoprotein-cholesterol (LDL-C) while simultaneously increasing high density lipoprotein-cholesterol (HDL-C) levels and improving HDL-particle functionality. These lipoprotein modifications may provide a novel pathway for Alzheimer disease (AD) prevention through effects on lipid modulation, antioxidant activity, and neuro-inflammation. This approach could prove particularly beneficial for APOE4 carriers, who face elevated risks for both AD and atherosclerotic cardiovascular disease (ASCVD). To examine the effects of obicetrapib, an oral CETP inhibitor, on biomarker changes indicative of AD pathology among patients with ASCVD DESIGN: This was a pre-specified substudy of the BROADWAY trial, a phase 3, double-blind, placebo-controlled pivotal registration trial to evaluate the LDL-C lowering efficacy of obicetrapib in adult patients with established ASCVD and/or heterozygous familial hypercholesterolemia (HeFH), whose LDL-C was not adequately controlled, despite being on maximally tolerated lipid-lowering therapy. The trial was conducted across 188 sites in China, Europe, Japan, and the United States. Participants were recruited from cardiology clinics and lipid specialty centers from 2021 to 2024. Participants with ASCVD in BROADWAY who had known ApoE status and phosphorylated tau-217 (p-tau217) measured at baseline and 12 months. Participants in BROADWAY were randomized 2:1 to receive oral obicetrapib 10 mg daily or placebo for 12 months. AD plasma biomarkers were measured at baseline and 12 months using standardized SIMOA assays. The key outcome measure of interest was change in plasma p-tau217 from baseline to 12 months. Other outcome measures included changes in p-tau217/(Aβ42:40), p-tau181, glial fibrillary acidic protein (GFAP), and neurofilament light chain (NfL). The analysis population consisted of 1535 (61 %) of the 2530 BROADWAY participants. Median age was 67 years and 67.0 % were male. Baseline p-tau217 levels varied significantly by ApoE subgroups, with ApoE4 carriers generally having higher concentrations and ApoE4/E4 participants exhibiting the highest median concentration (0.56 pg/mL). Obicetrapib significantly attenuated p-tau217 increases compared to placebo (adjusted mean 2.09 % vs 4.94 %; P = 0.025). Treatment differences were most pronounced in ApoE4 carriers, where adjusted mean increases were 1.92 % and 6.91 %, for obicetrapib and placebo, respectively (P = 0.041). Furthermore, among ApoE4/E4 participants, there was a 7.81 % adjusted mean decrease in p-tau217 with obicetrapib compared to a 12.67 % increase with placebo, representing a 20.48 % treatment difference (P = 0.010). Positive trends were observed across secondary biomarkers, with obicetrapib also significantly limiting increases in the p-tau217/Aβ42:40 ratio compared to placebo (2.51 % vs 6.55 %; P = 0.004). In addition, among ApoE4/E4 participants, obicetrapib demonstrated significant effects on GFAP (-6.39 % vs +8.85 %; P = 0.006) and NfL (-10.49 % vs +6.82 %; P = 0.020). Strong correlations were observed between end-of-study obicetrapib plasma concentrations and biomarker improvements (r=-0.64), suggesting CETP inhibition as a potential mechanism, although other drug effects may also contribute to these changes. Obicetrapib significantly slowed AD biomarker progression over 12 months in participants with ASCVD, with the greatest effects in ApoE4 carriers. Among ApoE4/E4 participants, obicetrapib reduced p-tau217 levels by a placebo-adjusted 20.48 % and demonstrated consistent effects across multiple AD biomarkers. These findings represent the first demonstration of an oral intervention capable of reducing both beta-amyloid and tau pathology biomarkers in ApoE4 carriers, offering a potential preventive strategy for this high-risk population who currently have no effective prevention options. Future research will need to establish whether these biomarker changes translate to clinical benefits in dedicated AD prevention trials. ClinicalTrials.gov Identifier: NCT05142722. Show less

Despite the well-established benefits of statin therapy in reducing atherosclerotic cardiovascular disease (ASCVD) risk, many patients fail to achieve recommended low-density lipoprotein cholesterol (LDL-C) targets or experience statin intolerance, necessitating alternative approaches. This review examines advances in non-statin lipid-lowering therapies, focusing on proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors (monoclonal antibodies and inclisiran), bempedoic acid, and other non-statin lipid medications. We evaluate their mechanisms of action, clinical efficacy, and safety profiles on the basis of landmark trials. A conceptual framework for personalized lipid management is proposed, addressing residual cardiovascular risk, statin intolerance, and complex patient profiles. Clinical decision pathways are presented for high-risk patients, statin-intolerant individuals, and those with adherence challenges. We explore emerging therapies targeting novel pathways, including lipoprotein(a), apolipoprotein C-III inhibitors, angiopoietin-like protein 3 (ANGPTL3) inhibitors, cholesteryl ester transfer protein (CETP) inhibitors, and gene-editing technologies. Implementation barriers, including cost considerations, insurance challenges, and global access disparities, are discussed alongside solutions. Show less

Childhood obesity is associated with alterations in lipoprotein metabolism and increased oxidative stress, assessed by lipid peroxidation products, reactive oxygen species (ROS) and nitric oxide (NO) levels, oxidized/reduced glutathione (GSH/GSSG) ratio, and the activities of superoxide dismutase (SOD) and catalase. High-density lipoproteins (HDL) play an antioxidant role, conditioned by cholesteryl ester transfer protein (CETP), paraoxonase (PON) 1, lecithin:cholesterol acyltransferase (LCAT), lipoprotein-associated phospholipase A This study aims to evaluate HDL antioxidant capacity in children and adolescents with obesity and the status of its conditioning factors. Thirty children and adolescents, 15 with obesity and 15 normal-weight controls were studied in a cross-sectional observational study. Lipid profile and high-sensitivity C-reactive protein were assessed using standardized methods. Lipid peroxidation products, ROS, NO, GSH and GSSG levels, and catalase, SOD, CETP, LCAT, PON 1 (PON and arylesterase [ARE]) and Lp-PLA Children with obesity showed lower HDL cholesterol and apo A-I levels (P < .01), reduced CETP (P < .05), ARE (Lp-PLA Children and adolescents with obesity exhibited reduced HDL antioxidant activity, alterations in its conditioning factors, intrinsic oxidative modification of HDL particles, and increased oxidative stress. These alterations may affect long-term cardiovascular risk in children and adolescents with obesity. Show less

Cholesteryl ester transfer protein (CETP) is a crucial therapeutic target for combating cardiovascular disease (CVD) due to its strong influence in modulating high-density lipoprotein (HDL) levels. CETP is responsible for the bidirectional transfer of cholesteryl esters (CEs) and triglycerides (TGs) between different lipoprotein fractions. Although CETP encounters both these neutral lipid substrates when it penetrates deep into lipoprotein cores and can acquire either lipid, prior studies have examined its conformational space only in the presence of CEs or TGs individually. Here, we investigate the uncharacterised dynamics of CETP in heterogeneous lipid environments (CE-TG and TG-CE) using molecular dynamics simulations. Compared to the stable, homogeneous CE-bound state, the introduction of TG, particularly in mixed CE/TG configurations, induces significant structural instability and protein expansion. Mixed-lipid occupancy leads to elevated flexibility in critical lipoprotein-binding loops and the distortion of vital secondary structural elements. Furthermore, large-scale collective motion analyses reveal that heterogeneous binding forces CETP into aberrant, asymmetric, and hyper-twisted conformations. This disrupts the symmetric bending-twisting balance essential for efficient lipid exchange. Free energy landscapes confirm that the TGs within the mixed-lipid systems exhibit varied conformational states and adopt orientations that deviate from their reported parallel N-N orientation for lipid transfer through CETP. These findings suggest that the simultaneous presence of CE and TG imposes considerable conformational strain, fundamentally impairing CETP's lipid transport mechanism and offering novel mechanistic insights for future CETP-targeted therapeutics.

To report the clinical characteristics of traditional (TTC) and W-shaped tracheal collapse (WTC) and the long-term outcomes of continuous extraluminal tracheal prosthesis (CETP) placement in dogs with grade IV tracheal collapse (TC). Retrospective case series. A total of 69 client-owned dogs. Medical records of dogs with grade IV TC, subclassified as TTC or WTC, treated using CETP between 2018 and 2021, were retrospectively reviewed. Clinical signs, diagnostic results, intraoperative findings, surgical complications, and clinical outcomes were analyzed. Of the 69 dogs, 45 had TTC and 24 had WTC. All were discharged after CETP placement. Preoperative stridor (p < .0001) and labored breathing (p = .0419) were more prevalent in patients with WTC than in those with TTC. The WTC group was 12.1 times more likely to require preoperative oxygen management than the TTC group (OR, 95% CI: 3.2-37.5). The 36-month postoperative survival rates were 75.7% and 90.9% in dogs with TTC and WTC, respectively. Postoperative laryngeal paralysis occurred in three dogs in the TTC group and two in the WTC group. Recurrent TC occurred in one dog in the TTC group and two in the WTC group. Seven of the eight dogs with postoperative complications required surgical intervention or intraluminal stent placement. Although dogs with WTC showed more severe preoperative respiratory symptoms, their postoperative outcomes were comparable with those of dogs with TTC. CETP placement is a viable surgical treatment option for dogs with WTC, even those with severe respiratory symptoms. Show less

Selenium is experiencing renewed interest as a elemental semiconductor for a range of optoelectronic and energy applications due to its irresistibly simple composition and favorable wide bandgap. However, its high volatility and low radiative efficiency make it challenging to assess structural and optoelectronic quality, calling for advanced, non-destructive characterization methods. In this work, we employ a closed-space encapsulation strategy to prevent degradation during measurement and enable sensitive probing of vibrational and optoelectronic properties. Using temperature-dependent Raman and photoluminescence spectroscopy, we investigate grown-in stress, vibrational dynamics, and electron-phonon interactions in selenium thin films synthesized under nominally identical conditions across different laboratories. Our results reveal that short-range structural disorder is not intrinsic to the material, but highly sensitive to subtle processing variations, which strongly influence electron-phonon coupling and non-radiative recombination. We find that such structural disorder and grown-in stress likely promote the formation of extended defects, which act as dominant non-radiative recombination centers limiting carrier lifetime and open-circuit voltage in photovoltaic devices. These findings demonstrate that the optoelectronic quality of selenium thin films can be significantly improved through precise control of synthesis and post-deposition treatments, outlining a clear pathway toward optimizing selenium-based thin film technologies through targeted control of crystallization dynamics and microstructural disorder.

Diabetic foot ulcer (DFU), a severe complication of diabetes, impose substantial global health burdens. Dampness-heat syndrome (DHS), a common syndrome in traditional Chinese medicine (TCM), is highly prevalent among DFU patients and closely correlated with treatment response and prognosis. However, the molecular biomarkers associated with DFU in patients with DHS remain poorly understood. Serum 4D-data-independent acquisition (DIA) proteomics was performed on 16 DFU-DHS patients and six healthy controls (HCs). Differentially expressed proteins (DEPs) were screened by |fold change (FC)| > 1.2 and p < 0.05. Gene Ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG), and protein-protein interaction (PPI) analyses were conducted. Key biomarkers were validated via enzyme-linked immunosorbent assay (ELISA) in 28 independent DFU-DHS cases. A total of 201 DEPs were identified between DFU-DHS patients and HCs. Bioinformatics revealed DEPs enriched in lipid metabolism (high-density lipoprotein [HDL] remodeling and cholesterol metabolism) and complement-coagulation cascades. PPI network analysis revealed a core functional module centered on four proteins, APOA1, LCAT, PLTP, and CETP. ELISA validation confirmed the significant dysregulation of these four apolipoproteins in the independent DFU-DHS cohort (all p < 0.05 vs. HCs). The combination of the biomarkers APOA1, LCAT, PLTP, and CETP exhibited a high diagnostic efficacy for DFU-DHS, with an area under the curve (AUC) of 0.9672 based on receiver operating characteristic (ROC) analysis. To our knowledge, this is the first study to employ 4D-DIA proteomics on DFU-DHS. We identified four serum biomarkers (APOA1, LCAT, PLTP, and CETP) linked to dysregulated cholesterol metabolism in DFU-DHS patients, which show diagnostic potential and provide insights for integrating TCM syndrome differentiation with precision medicine.

The combination of Atractylodis Macrocephalae Rhizoma and Atractylodis Rhizoma (Baizhu-Cangzhu, BC) is a commonly used couplet medicine suitable for strengthening spleen function in the clinic. The combination of BC originates from the ancient Chinese medical text Zhang's Medical Expert. Ancient Chinese doctors often used a combination of these two drugs or their different processed products to supplement the spleen and resolve dampness and treat hyperlipidemia (HLP). However, no further research has been conducted on the characteristics of the effects of different combinations of its raw drug and processed products. The present study aimed to elucidate the regulatory effect of raw BC, stir-frying BC with bran, and their different combinations on HLP and the therapeutic characteristics of each sample, and promote their application in the treatment of HLP and related diseases. A HLP model was induced by feeding mice with a high-fat diet (HFD) for six weeks. Serum biochemical indicators levels were measured using a fully automatic blood biochemistry analyzer. HE staining was used to observe the pathological changes of liver and small intestine tissues, Oil-Red O staining and Masson staining was used to observe the lipid and collagen deposition in the liver tissue, respectively. The levels of inflammatory cytokines, gastrointestinal hormones, and lipid metabolism-related indicators in the serum were detected by ELISA. The expression of aquaporins (AQPs) in liver tissues and MUC2 in small intestinal tissues were detected by immunohistochemistry. The protein expression levels of AQPs in liver tissues and tight junction proteins in small intestinal tissues were measured by Western blotting. The expression and localization of ZO-1 protein in small intestinal tissues were detected by immunofluorescence. The BC group significantly reduced serum TC and LDL-C levels (P < 0.005). FBFC treatment lowered serum AST levels (P < 0.05) and increased CETP and PLTP levels (P < 0.05). IL-6 and AQP9 levels were reduced in all treatment groups (P < 0.05). In liver tissue, AQP3 expression was upregulated in the BC and FBC groups, while AQP8 expression increased in the BFC and FBC groups (P < 0.05). In small intestine tissue, AQP3 expression was elevated in the BC and BFC groups, and AQP8 was increased in the BFC, FBC, and FBFC groups (P < 0.05). ZO-1 expression was enhanced in the BFC, FBC, and FBFC groups, while Claudin-1 expression was higher in the BC and FBFC groups (P < 0.05). MUC2 expression was increased in the FBFC group (P < 0.05). Our findings demonstrated that BC, stir-frying BC with bran, and their various combinations exert distinct therapeutic characteristics in improving spleen deficiency and lowering lipid levels in HFD-induced HLP mice. The raw products showed stronger lipid-lowering effects, whereas the processed products were more effective in improving liver enzyme profiles, regulating gastrointestinal hormones, and repairing intestinal barrier dysfunction.

Obicetrapib, an oral cholesteryl ester transfer protein (CETP) inhibitor, has demonstrated potent LDL-C lowering in recent phase 2/3 trials. We evaluated Obicetrapib (1, 2.5, 5, and 10 mg) efficacy and safety in adults with dyslipidemia, with or without atherosclerotic cardiovascular disease (ASCVD) risk. We performed a meta-analysis of randomized controlled trials (RCTs) identified through PubMed, Cochrane, Scopus, and Web of Science up to June 2025. Dichotomous outcomes were analyzed as risk ratios (RRs) and continuous outcomes as mean differences (MDs), both with 95% confidence intervals (CIs). CRD420251107076. Six RCTs including 3399 patients were analysed. Compared with placebo, Obicetrapib significantly reduced LDL-C at 8-12 weeks (MD -27.66 mg/dL (-26.96%); 95% CI -33.62 to -21.70; p < 0.0001) and non-HDL-C (MD -35.41 mg/dL (-28.08%); 95% CI -39.42 to -31.39; p < 0.0001). It also increased HDL-C (MD 70.85 mg/dL (141.7%); 95% CI 62.56-79.15; p < 0.0001) and improved achievement of LDL-C targets: <55 mg/dL (RR 6.42; 95% CI 5.15-8.01), <70 mg/dL (RR 2.56; p < 0.0001), and < 100 mg/dL (RR 1.34; p < 0.0001). No significant differences were found in total adverse events (p = 0.41) or serious adverse events (p = 0.37). Obicetrapib provides substantial improvements in lipid parameters with a favourable short-term adverse events rate. These results support its role as a potential adjunctive lipid-lowering agent irrespective of ASCVD risk. Longer-term trials are warranted to confirm its durability, cardiovascular outcomes, and safety. Show less

Despite the widespread use of lipid-lowering therapies, a significant proportion of patients with atherosclerotic cardiovascular disease fail to achieve the recommended LDL-cholesterol targets, thus remaining at high residual risk. Inhibition of cholesteryl ester transfer protein (CETP) has long been considered a pharmacological strategy, but has historically been hindered by clinical failures. Obicetrapib, a next-generation CETP inhibitor, has recently shown promising results in terms of efficacy and safety. This review critically examines the physiology of CETP, the negative outcomes of earlier CETP inhibitors, and the emerging evidence on obicetrapib, highlighting the potential role of this molecule in the treatment of hypercholesterolemia and in the secondary prevention of atherosclerotic cardiovascular disease.

Familial hypercholesterolemia (FH) is characterized by elevated low-density lipoprotein cholesterol (LDL-C) and increased risk of premature coronary atherosclerosis. Functional aspects of high-density lipoprotein (HDL), including cholesterol transfer capacity, may contribute to cardiovascular risk heterogeneity in FH. To investigate whether cholesterol transfer to HDL and other HDL-related parameters are associated with coronary artery disease (CAD) in patients with heterozygous FH (HeFH). Fifty-three genetically confirmed FH patients (mean age: 49.2 years; 73.6% female) were included. Twenty-seven had plaques, while 26 had no vessel abnormalities as determined by coronary computed tomography angiography. The transfer of both unesterified and esterified cholesterol (UC and EC) to HDL, as well as HDL antioxidant capacity, particle size, and subfractions, plasma concentrations of cholesteryl ester transfer protein (CETP) and lecithin-cholesterol acyltransferase (LCAT), and paraoxonase-1 (PON-1) activity were assessed. Family history of premature CAD (P < .028) and tendinous xanthomas (P = .014) were more frequent in those with plaques. No differences were found in apolipoprotein (apo) B, LDL-C, LDL-C year score, lipoprotein(a), non-HDL-C, apo A-I, HDL-C, HDL subfractions, or triglycerides. Transfer of lipids to HDL and antioxidant capacity did not differ between the groups. LCAT concentrations and PON-1 activity were also similar. In contrast, CETP concentration was higher in those with plaques (P < .008). However, only family history of early CAD (odds ratio [OR]: 4.12, 95% CI, 1.23-13.80, P = .022) and xanthomas (OR: 3.65, 95% CI, 1.06-12.60, P = .040) were independently associated with plaques. Among patients with HeFH, no HDL-related parameter was independently associated with subclinical CAD. Show less

Cholesteryl ester transfer protein (CETP) plays a central role in plasma lipid transport, facilitating the exchange of neutral lipids, such as cholesteryl esters and triglycerides, between lipoproteins. Despite the existence of several lipid-carrying/binding proteins in the family, such as lipopolysaccharide-binding protein (LBP), bacterial permeability increasing protein (BPI), and phospholipid transfer protein (PLTP), the structural and mechanistic uniqueness of CETP in neutral lipid transfer remains underexplored. Moreover, the involvement of PLTP in neutral lipid transfer is still debated, with researchers presenting conflicting mechanisms. Therefore, this study investigates the distinct structural ability of CETP in mediating neutral lipid exchange compared to other lipid-binding proteins. The study also emphasizes that simple protein modeling based on templates may not guarantee structural integrity unless validated through simulations. To achieve our objectives, we employed molecular docking, comparative molecular dynamics simulations, structural analysis, and lipid-protein interaction profiling with representative neutral lipids. In addition, protein-lipid affinities, tunnel architecture, and conformational flexibility were examined to characterize CETP's unique features and evaluate the quality of the constructed model for PLTP. The results demonstrated that a tunnel-like hydrophobic channel in CETP facilitates bidirectional neutral lipid transfer, unlike the compartmentalized binding pockets observed in other proteins. In addition, the neutral lipids' unfavorable conformational orientation was not affected in PLTP, whereas the same unfavorable conformation is changed to a favorable conformation in CETP, making only the lipid-carrying protein have the ability to transfer the neutral lipids. In conclusion, our findings highlight that the CETP is a specialized neutral lipid carrier with a unique structural mechanism distinct from typical lipid-binding proteins. This comparative insight enhances understanding of the structural plasticity of each lipid-carrying protein and the reliability of the modeled structure. Show less

On the basis of life-style changes and statins, current guidelines recommend early combination therapy to reduce LDL cholesterol (LDL-C). Available and future novel non-statin lipid-lowering therapies may have specific advantages in patients with (1) statin intolerance, (2) elevated triglyceride-rich lipoproteins, (3) elevated lipoprotein(a), and (4) rare genetic dyslipidemias. Currently available treatment options to lower LDL-C with proven cardiovascular benefit include statins, ezetimibe, bempedoic acid, and PCSK9 antibodies. The 2025 update of the ESC/EAS dyslipidemia guidelines incorporates recommendations on early combination treatment and management of rare dyslipidemias, which are detailed in this review. Novel LDL-C-lowering strategies, targeting PCSK9 and CETP, may further improve dyslipidemia management. Drugs in development with profound effects on lipoprotein(a) or triglyceride concentration may allow for specific modification of residual cardiovascular risk. Innovative DNA-targeting therapies are moving towards clinical testing in larger studies. Various treatment options for patients with dyslipidemia and distinct characteristics have become available. Future developments may allow for even more tailored treatment, depending on dyslipidemia phenotype. Show less

We recently showed that patients with atherosclerotic cardiovascular disease (ASCVD) carry a substantial but largely unrecognized burden of early Alzheimer's disease (AD) pathology. In the BROADWAY pivotal phase 3 lipid-lowering trial, nearly half of participants with high-risk ASCVD had plasma p-tau217 concentrations above thresholds associated with preclinical AD, yet none had undergone evaluation for cognitive impairment. In this population, apolipoprotein E ε4 (APOE4) carriers were disproportionately represented among those with the highest p-tau217 levels. These findings expose a critical gap between cardiovascular care and dementia prevention and raise the question whether interventions targeting shared pathophysiology could address both conditions simultaneously. Cholesteryl ester transfer protein (CETP) inhibition has emerged as a candidate for this dual role. In BROADWAY, obicetrapib reduced p-tau217 progression across the study population, with effects most pronounced in APOE4 carriers. In fact, treatment differences favoring obicetrapib were observed across all measured AD biomarkers in high-risk subgroups, including neurofilament light chain, glial fibrillary acidic protein, and the amyloid-beta (Aβ) 42:40 ratio. Unlike approaches that target downstream pathology, such as amyloid plaques already deposited in the brain or the inflammatory consequences of established disease, CETP inhibition may address the upstream processes involved in initiating the pathological cascade: lipid dysregulation, cholesterol ester accumulation in glial cells, impaired cholesterol efflux, lipid peroxidation, oxysterol formation, and deficient antioxidant transport. This review examines the biological rationale linking APOE4 status to disordered lipid metabolism in both peripheral and central compartments, the genetic and epidemiological evidence supporting CETP as a therapeutic target, the mechanisms through which CETP inhibition might confer neuroprotection, and the clinical data suggesting obicetrapib as the first oral agent associated with favorable changes in AD biomarkers across both amyloid and tau axes in individuals at high genetic risk for the development of AD.

Colorectal cancer (CRC) liver metastases remain refractory to immunotherapy due to a profoundly immunosuppressive tumor microenvironment. Here, we conducted a prospective clinical study enrolling 18 patients with microsatellite-stable CRC liver metastases treated with high-dose radiotherapy (RT) followed by anti–PD-1 immune checkpoint inhibitors (RT–ICI). Integrative analysis of single-cell RNA-sequencing, spatial transcriptomics, and peripheral immune profiling revealed that RT–ICI therapy reprograms both tumor-intrinsic and immune compartments. RT triggered the emergence of an APOA2⁺ tumor cell state characterized by enhanced lipid metabolic activity and transient elevation of circulating HDL. This metabolic reprogramming, in turn, promoted systemic activation of CETP⁺ M2-like macrophages, a population marked by high LXR/RXR transcriptional activity and enriched expression of immunosuppressive and lipid-processing genes. Despite their expansion, CETP⁺ macrophages localized preferentially to non-irradiated tumor regions, suggesting a distal immunometabolic effect driven by HDL-mediated signaling. Concurrently, combination therapy expanded GZMB⁺ effector T cells and induced a novel population of inflammatory–toxic T cells (IT_T), which exhibited high cytotoxicity and spatial co-localization with CXCL10⁺ macrophages. Ligand–receptor analysis and pseudotime modeling revealed that irradiated tumor cells acted as “in situ vaccines” by enhancing MHC–TCR interactions and promoting T cell differentiation along non-exhausted cytotoxic lineages. Together, these findings reveal a dual mechanism by which RT–ICI therapy enhances local anti-tumor immunity while modulating systemic lipid metabolism and macrophage polarization, offering insights for combinatorial immunotherapy design in immunologically “cold” tumors.

This study aimed to assess the prevalence of genetic variants responsible for extreme levels of high-density lipoprotein cholesterol (HDL-C) and evaluate the adequacy of current thresholds for genetic testing of HDL-related dyslipidemia. Using data from the Tromsø Study, a population-based cohort in Northern Norway, we identified 210 individuals with HDL-C levels ≤ 0.5 mmol/L or ≥ 3.0 mmol/L. Six HDL-related genes (ABCA1, APOA1, CETP, LCAT, PLTP, SCARB1) were sequenced in these participants. We classified variants according to ACMG guidelines, incorporating functional assays and UK Biobank data for additional phenotype-genotype associations. We identified 38 variants of interest across six HDL-related genes, of which 10 were considered potentially causative, found in 14 individuals. Genetic causes were detected in 33.3% of individuals with low HDL-C and 5.05% of those with high HDL-C. Sex-specific analyses showed that using HDL-C thresholds aligned with population distributions improved detection of individuals with pathogenic variants, particularly among women with high HDL-C and men with low HDL-C. These findings suggest that current uniform thresholds may overlook clinically relevant cases and that incorporating sex-specific HDL-C distributions could enhance the identification of individuals with suspected genetic HDL disorders. Genetic testing for HDL-related dyslipidemia is underutilized, with many individuals not meeting the current extreme HDL-C threshold criteria. Revised sex-specific thresholds for genetic testing will improve the identification of pathogenic variants and provide more accurate diagnoses of HDL-related disorders. Continued research is essential to refine our understanding of HDL genetics and its clinical implications. Show less

Prior to a cardiovascular outcomes trial (CVOT), novel cholesterol-lowering therapies undergo phase 2/3 studies for their lipid and atherosclerotic effects and safety (non-CVOTs). Since the occurrence of major adverse cardiovascular events (MACE) is part of the safety assessment, nominal reductions or increases may be observed prior to definitive testing of the effect in a CVOT. To investigate if the observed MACE treatment effect in non-CVOT lipid-lowering registration studies holds value in predicting the outcome in a CVOT trial, typically reported later than the initial lipid-lowering studies. We reviewed recent development programs for cholesterol-lowering drugs that had completed non-CVOT and CVOT studies. MACE data were compared for phase 2/3 non-CVOT versus pivotal CVOT results. Our primary outcome was a qualitative comparison for directionally concordant consistency in MACE risk ratio treatment effects (harm, neutrality, or benefit). Correlation analysis was also performed. Seven drugs were reviewed in 3 cholesterol-lowering classes: CETP inhibitors, bempedoic acid, and PCSK9 inhibitors. Concordance in non-CVOT vs CVOT results was seen in 6 of 7 drugs. One drug (dalcetrapib) had a trend for benefit observed, albeit with very small numbers, in early development, but showed a neutral CVOT. There was a moderate correlation between the risk reductions or increases from the non-CVOTs and CVOTs: Within the limitations of the drugs studied and the variability in MACE definitions, there is value in the results of non-CVOTs to predict the CVOT outcome.

Atherosclerotic cardiovascular diseases are a leading global cause of death, driven significantly by elevated low-density lipoprotein cholesterol levels. Despite the emergence of effective lipid-lowering therapies such as statins and other agents, a significant proportion of high-risk patients fail to reach the recommended low-density lipoprotein cholesterol targets. This highlights a critical unmet need for additional lipid-lowering therapies that are not only efficacious and orally administered, but also demonstrate durable safety and cardiovascular benefits. CETP (cholesteryl ester transfer protein) inhibition alters lipid metabolism by preventing the transfer of cholesteryl esters from high-density lipoprotein to apolipoprotein B-containing lipoproteins, thereby reducing atherogenic cholesterol burden. CETP inhibitors have had a challenging development history due to off-target effects observed in early compounds like torcetrapib. However, obicetrapib is a highly selective and hydrophilic CETP inhibitor that heralds a promising new generation of drugs with robust lipid-lowering capabilities and a favorable safety profile. This review presents a comprehensive overview of obicetrapib's mechanism of action, its pharmacokinetic and pharmacodynamic profiles, and a detailed critical assessment of its clinical development through various pivotal trials including TULIP (TA-8995: Its Use in Patients With Mild Dyslipidemia), ROSE (Trial Evaluating Obicetrapib in Combination With Ezetimibe), ROSE2 (Phase 2b ROSE Trial Evaluating Obicetrapib in Combination With Ezetimibe), BROADWAY (Randomized Study to Evaluate the Effect of Obicetrapib on Top of Maximum Tolerated Lipid-Modifying Therapies), BROOKLYN (Obicetrapib on Top of Maximum Tolerated Lipid-Modifying Therapies, TANDEM (Study of Obicetrapib and Ezetimibe Fixed Dose Combination on Top of Maximum Tolerated Lipid-Modifying Therapies), and the ongoing PREVAIL (Cardiovascular Outcome Study to Evaluate the Effect of Obicetrapib in Patients With Cardiovascular Disease) cardiovascular outcomes trial. We compare the efficacy, safety, and tolerability of obicetrapib against prevailing treatment options, positioning it as a potential oral adjunct to maximally tolerated lipid-lowering regimens in the current lipid management landscape.

Overweight and obesity are widespread in Mexico, often linked to dyslipidemia and higher cardiovascular risk. The search for safe and effective treatments has promoted interest in natural supplements such as Ashwagandha (Withania somnifera), recognized for its adaptogenic and potential lipid-lowering properties. To assess the impact of Ashwagandha supplementation on serum lipid profiles and anthropometric parameters in Mexican adults with overweight and obesity. A double-blind, randomized, placebo-controlled pilot clinical trial was carried out with 43 adults (n = 17 in the control group and n = 21 in the intervention group) over 40 days. Participants followed a monitored diet and received one daily capsule containing 500 mg of Ashwagandha or a placebo, in addition to a guided unrestricted dietary plan. Anthropometric and biochemical measurements were taken at baseline and after the intervention. In silico analysis was also performed to examine the binding affinity of Ashwagandha bioactive compounds to key proteins involved in lipid metabolism. Ashwagandha supplementation did not produce statistically significant changes in body weight, body mass index (BMI), or waist circumference (WC). However, significant reductions were observed in triglyceride and VLDL-c levels (p = 0.0082 and p = 0.0321, respectively). In silico results supported these findings, showing favorable interactions between compounds such as withanolide A and lipid metabolism targets, including AMPK, CETP, and LPL. Ashwagandha supplementation improved serum lipid profiles in adults with overweight and obesity, suggesting potential lipid-lowering effects when combined with a prescribed dietary plan. Also, it was possible to elucidate some metabolic pathways in which Ashwagandha composition has an influence on producing the reported effects. Further long-term studies with controlled dietary intake are needed to confirm these findings and clarify the underlying molecular mechanisms. Show less

This investigation elucidates the critical molecular determinants associated with the comorbidity of osteoporosis (OP) and periodontitis (PD) through proteomic profiling, while delineating the regulatory function of CD44 in experimental periodontitis in an OP murine model. Phase I involved collecting serum specimens from patients with OP+PD (n = 3) and healthy controls (n = 6) undergoing routine health evaluations at our institution for comparative proteomic analysis. Subsequent translational validation of differentially expressed genes (DEGs) and associated signaling cascades was conducted across clinical specimens and OP+PD murine models. To mechanistically characterize CD44's role in PD progression under osteoporotic conditions, an OP murine model was generated through bilateral ovariectomy, followed by experimental PD induction via ligature placement. Comprehensive assessments included histomorphometric alterations via hematoxylin-eosin staining, microarchitectural bone analysis at the maxillary first molar region using micro-CT, and immunoblotting evaluation of phosphoinositide-3-kinase (PI3K)/Akt pathway components. Parallel network pharmacological screening coupled with molecular docking simulations was executed to identify bioactive constituents of Angelica sinensis with therapeutic potential. Proteomic interrogation identified CST3, A2M, CD44, CDH13, CETP, and VWF as candidate pathogenic mediators in OP+PD pathogenesis. In our hands, gene set enrichment analysis revealed that PI3K/Akt signaling functions as a principal mediator of OP+PD disease progression. Quantitative reverse-transcription PCR-based validation confirmed significant CD44 upregulation in both clinical and experimental OP+PD cohorts. In vivo modulation via CD44 suppression significantly restored periodontal tissue integrity, reduced inflammatory cell infiltration, and strengthened alveolar bone microarchitecture in OP mice, concomitant with PI3K/Akt pathway inhibition. Network pharmacology revealed glycitein as the primary bioactive phytochemical in Angelica sinensis, with CD44 identified as its central molecular target. Glycitein improved alveolar bone structure in OP+PD mice, increasing bone volume fraction (BV/TV), trabecular thickness (Tb.Th), bone mineral density (BMD), and reducing trabecular number (Tb.N), bone surface-to-bone volume ratio (BS/BV), indicating healthier bone quality, mechanistically attributed to CD44 signaling axis attenuation.
