HDL is made up of different types of particles that vary in size, protein and lipid composition, and function. This review focuses on recent findings on the specific roles of HDL subpopulations defined by size in CVD.Recent findings: Small HDL particles are more effective than larger particles at promoting cellular cholesterol efflux because apolipoprotein A-I on their surface better engages ABCA1 (ATP binding cassette subfamily A member 1). In contrast, large HDL particles bind more effectively to scavenger receptor class B type 1 on endothelial cells, which helps prevent LDL from moving into the artery wall. The specific role of medium-sized HDL particles, the most abundant subpopulation, is still unclear.Summary: HDL is made up of subpopulations of different sizes of particles, with selective functional roles for small and large HDLs. The function of HDL may depend more on the size and composition of its subpopulations than on HDL-C levels. Further research is required to understand how these different HDL subpopulations influence the development of CVD.","PeriodicalId":11109,"journal":{"name":"Current opinion in lipidology","volume":" ","pages":"111-118"},"PeriodicalIF":3.8,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12003705/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142496782","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Traditional therapies, including fibrates and omega-3 fatty acids, have shown limited efficacy in controlling triglyceride (TG) levels and cardiovascular risk. This review explores the role of emerging therapies that target TG and TRL metabolism via novel biochemical pathways.Recent findings: Apolipoprotein C-III inhibitors appear most effective for patients with variants of severe HTG, particularly multifactorial and familial chylomicronemia syndromes, by enhancing TRL metabolism through both lipoprotein lipase-dependent and independent mechanisms. Angiopoeitin-like proteins 3 and 4 inhibitors appear most useful for mixed hyperlipidemia, with favorable effects across the entire spectrum of apoB-containing atherogenic lipoproteins. For patients with HTG and concomitant complications of insulin resistance, including metabolic associated steatotic liver disease and type 2 diabetes mellitus, fibroblast growth factor-21 analogs may provide significant benefit.Summary: HTG is a diverse condition. Apolipoprotein C-III inhibitors, angiopoeitin-like proteins 3 and 4 inhibitors, and fibroblast growth factor-21 analogs represent significant advancements in the treatment of HTG, offering new hope for effectively managing this condition across its full spectrum of disease.","PeriodicalId":11109,"journal":{"name":"Current opinion in lipidology","volume":" ","pages":"119-129"},"PeriodicalIF":3.8,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143448476","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Alveolar lipid homeostasis is disturbed in chronic lung diseases and contributes to disease pathogenesis through extracellular localization in the alveolar lumen or intracellular accumulation in AM. This review aims to provide a focused overview of the state of knowledge of AM, their ontogeny and development during health and disease, and how dysregulated AM lipids play a key role in disease processes, from initiation to resolution.Recent findings: While lipid-laden macrophages are observed across a broad spectrum of lung diseases, their occurrence has largely been considered consequential. Recent advances in lipidomic profiling of single cell types has revealed that disturbances to lipid homeostasis occur early in disease in tissue-resident cells. Comparisons between inflammatory and fibrotic injury models reveal specific alveolar macrophage subsets with different lipid utilization that contribute to the disease process.Summary: Understanding the intricate web of AM population seeding and development and how this niche is perturbed by lipid disturbances may help provide leverage for new interventions.","PeriodicalId":11109,"journal":{"name":"Current opinion in lipidology","volume":" ","pages":"153-162"},"PeriodicalIF":3.8,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12043416/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143779397","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite this, the intracellular synthesis, trafficking, and secretion of chylomicrons remains only partly understood. The purpose of this review is to summarize the role of established proteins in this process and bring attention to recently identified proteins to provide an up-to-date model of chylomicron biosynthesis.Recent findings: Recently, several proteins have been shown to play a role in the initial formation and lipidation of chylomicrons at the endoplasmic reticulum (ER), which include: TM6SF2, PLA2G12B, PRAP1, and SURF4. In addition, mitochondria have been implicated in chylomicron metabolism, but mechanistic insight is missing. The trafficking of chylomicrons from the ER to the Golgi, and the subsequent trafficking from the Golgi to the basolateral side of enterocytes, however, remains a mystery.Summary: Progress in the chylomicron biosynthesis field is largely associated with findings in VLDL biosynthesis. In addition, increased insight in events after prechylomicrons leave the ER is needed. Given the important role of chylomicron biosynthesis in whole-body lipid metabolism, further research into the molecular mechanisms is warranted.","PeriodicalId":11109,"journal":{"name":"Current opinion in lipidology","volume":" ","pages":"145-152"},"PeriodicalIF":3.8,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12052055/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143728768","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This review explores the complexities of FH care during pregnancy.Recent findings: The worldwide burden of FH is much greater than previously thought. Still, underdiagnosis and undertreatment are substantial, necessitating increased awareness, genetic screening efforts, and better access to diagnostic tools. Although there is guidance for implementing best practices in the care of FH, including pregnancy, currently, there are no evidence-based guidelines that address HoFH at the time of pregnancy planning or during pregnancy and lactation.Summary: FH management in pregnancy requires a reasonable balance between fetal safety and maternal LDL-C control. Discontinuing lipid-lowering medication during pregnancy and the postpartum period needs to be considered, and in severe cases, lipoprotein apheresis may be an appropriate substitute. Comprehensive patient care requires coordination by genetic counselors, cardiologists, lipidologists, and obstetricians. The management of HoFH in pregnancy requires further research efforts, enhancement of public knowledge, and worldwide cooperation. By focusing on these areas, we can make significant progress in diagnostics and develop efficient management plans for improving outcomes among pregnant women with HoFH.","PeriodicalId":11109,"journal":{"name":"Current opinion in lipidology","volume":" ","pages":"138-144"},"PeriodicalIF":3.8,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143595762","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Conventional lipid-lowering therapies have no substantial effect on circulating Lp(a) levels, leading current guidelines to focus on managing traditional cardiovascular risk factors. New therapies, including antisense oligonucleotides and small interfering RNAs, target Lipoprotein(A) [LPA] gene translation to reduce apo(a) synthesis and Lp(a) particles formation.

While Lp(a) contributes to residual cardiovascular risk in T2D, lower levels paradoxically increase the risk of developing T2D. This review explores Lp(a)'s dual role in cardiometabolic disease, its association with T2D, and emerging Lp(a)-lowering therapies.Recent findings: Large-scale studies confirm Lp(a) as a potent risk factor for cardiovascular events in T2D, with lower Lp(a) thresholds increasing risk compared to nondiabetic individuals. Observational and genetic studies reveal an inverse relationship between Lp(a) and T2D risk, linked to insulin dynamics, Kringle IV-type-2 repeat variants, and metabolic pathways. Emerging evidence suggests a connection between Lp(a), nonalcoholic fatty liver disease, and statin use. However, Mendelian randomization analyses have yielded conflicting results, leaving key mechanistic questions unresolved.Summary: Lp(a) plays a complex role in cardiometabolic health, acting as both a cardiovascular hazard and a potential metabolic marker in T2D. The paradoxical association of low Lp(a) with increased T2D risk challenges conventional perspectives and raises concerns regarding Lp(a)-lowering interventions. Further research is needed to clarify causality, refine risk stratification, and guide clinical decisions for Lp(a) modulation in T2D patients.","PeriodicalId":11109,"journal":{"name":"Current opinion in lipidology","volume":" ","pages":""},"PeriodicalIF":3.8,"publicationDate":"2025-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144076634","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We will here review recent observations indicating that treatment with the anti-oxidized LDL antibody orticumab specifically inhibits plaque inflammation.Recent findings: The effect of orticumab on coronary inflammation in a randomized, double-blind, placebo-controlled pilot phase 2a trial in subjects with moderate to severe psoriasis is a new and recent finding. Coronary inflammation was assessed by calculation of the fat attenuation index (FAI)-Score in the pericoronary adipose tissue in coronary computed tomography angiograms. After 15 weeks of treatment the mean FAI-Score of the three main coronary arteries was significantly reduced in the orticumab group while no change occurred in the placebo group.
