Outcomes and future activities of the ‘Pan-European network in Lipidomics and EpiLipidomics – EpiLipidNET’

Abstract

<h3>Background</h3><p>Lipidomics and its branch epilipidomics are rapidly advancing fields that explore the roles of native and modified lipids (e.g., oxidized, nitrated and halogenated lipid species), respectively, in biological systems. Dysregulation of lipid metabolism and signaling contributes to numerous diseases, including cardiovascular, metabolic, neurodegenerative, and inflammatory conditions. However, multiple challenges, including lack of standardization, limited data integration, and poor clinical translation, hinder progress. To address these, the COST Action EpiLipidNET (CA19105) established a pan-European network fostering collaboration across disciplines to accelerate lipid science and its application to health and disease.</p><h3>Aim of review</h3><p>This review outlines the achievements of EpiLipidNET over its four-year duration, highlights key scientific contributions across five thematic working groups, and presents the future direction of its ongoing activities. The aim is to demonstrate how a collaborative, interdisciplinary framework can catalyze innovation in lipidomics and epilipidomics, enhance methodological harmonization, support early-career researchers, and bridge the gap between basic science, clinical translation, industry, stakeholders, and public engagement.</p><h3>Key scientific concepts of review</h3><p>EpiLipidNET structured its networking activities around (i) harmonization of analytical workflows, (ii) development of epilipidomics tools and data integration strategies, (iii) translational studies for clinical lipid biomarkers, (iv) investigation of lipid signaling mechanisms, and (v) dissemination and outreach. The network supported over 460 members globally, launched multiple training schools and scientific missions, produced 110+ publications, and fostered new initiatives in endothelial membrane lipidomics, food lipidomics, plant and algae lipids, and redox lipid biology. Its integrative approach sets a foundation for continued progress toward precision medicine and sustainable health interventions through lipid science.</p>
