Yale researchers map structures of lipid‑transport proteins linked to neurodegeneration

Researchers at Yale School of Medicine have carried out the first comprehensive structural analyses of a class of proteins whose dysfunction is linked to a range of neurodegenerative disorders. By employing advanced cryo‑electron microscopy and X‑ray crystallography, the team mapped the three‑dimensional arrangements of these proteins at near‑atomic resolution, revealing previously unseen conformational states that may underlie their pathogenic aggregation.

The study provides critical context for understanding how subtle structural changes can trigger the misfolding and aggregation processes that drive diseases such as Alzheimer’s, Parkinson’s, and amyotrophic lateral sclerosis. The detailed maps also highlight specific binding pockets and interaction surfaces that could serve as targets for small‑molecule inhibitors or biologics designed to stabilize the native protein conformation.

These findings lay a foundation for future therapeutic strategies aimed at preventing or reversing protein aggregation. By clarifying the structural basis of protein dysfunction, the research opens new avenues for drug discovery and offers a benchmark for subsequent investigations into the molecular mechanisms of neurodegeneration.
