Year after year, groundbreaking research in lipid metabolism fuels new discoveries, transforming our understanding of cellular function and unlocking potential treatments for metabolic disorders and neurodegenerative diseases. At the 91ÑÇÉ«´«Ã½ annual meetings, scientists come together to share the latest breakthroughs — each study building on the last — to push the boundaries of what’s possible in basic research and clinical innovation.

Membrane dynamics and lipid–protein interactions

Lipid–protein interactions are central to maintaining cell membrane integrity, signaling, and protein activity. Disruptions in these interactions have been linked to diseases like Alzheimer's, cardiovascular disorders and autoimmune diseases, making them crucial targets for therapeutic research.

One notable abstract used cryogenic electron microscopy to explore ABHD5, a regulator of lipid homeostasis. This research revealed how ABHD5 interacts with lipids and regulates adipose triglyceride lipase activity, which is essential for lipid breakdown and energy balance. in ABHD5 can lead to nonalcoholic fatty liver disease, or NAFLD. Therefore, this research lays a foundation for potential NAFLD gene therapies.

In the same year, an on NAFLD investigated oxidized phospholipids that are recognized by an antibody. The researchers used a viral vector to express the antibody in the liver, which protected mice from liver damage and fibrosis. This suggests that oxidized phospholipids could serve as biomarkers for NAFLD and offers new therapeutic possibilities targeting lipid abnormalities.

Building on foundational phospholipid research from previous years, a examined how extracellular crowding agents affect the membrane binding of antimicrobial peptides like Buforin II. This discovery informs researchers on how to design more effective peptides to combat pathogens.

Another explored lipid rafts — specialized membrane regions — and their impact on the human follicle-stimulating hormone receptor, or hFSHR, crucial for fertility. Mutations in the receptor motif that binds the membrane protein caveolin disrupted signaling, impairing spermatogenesis. These findings emphasize the importance of lipid–protein interactions in cellular function and health.

These studies advance lipid science by examining how lipids and proteins interact to influence cellular function and disease progression. Lipidomics research highlights the diagnostic potential of specific lipid species, while studies on caveolae — lipid-rich membrane domains — demonstrate how membrane structure regulates signaling pathways. Furthermore, research on oxidized phospholipids connects these molecules to oxidative stress in NAFLD, while investigations into the membrane protein caveolin reveal its role in controlling stress-related signaling.

By targeting these lipid–protein interactions, researchers may unlock new therapeutic strategies for NAFLD, reproductive disorders and endothelial dysfunction.
