An international consortium led by researchers at KTH/SciLifeLab published a comprehensive pan‑disease blood proteome atlas in Science, profiling proteins across more than 8,200 people spanning 59 diseases using Olink’s Explore and Explore HT platforms. The dataset measures up to 5,416 proteins and includes longitudinal sampling that revealed stable individual proteomic fingerprints and disease‑specific signatures. The team, including Mathias Uhlén, identified a core set of roughly 2,000 proteins consistently detected across serial samples and demonstrated that pan‑disease comparisons improve biomarker specificity versus single‑disease case‑control studies. A parallel SciLifeLab effort profiled 9,027 samples using Olink panels to map protein changes tied to aging and disease states. The open‑access atlas provides a resource for diagnostics and biomarker discovery, enabling researchers to distinguish disease‑specific protein changes from generalized inflammatory responses and to pursue longitudinal monitoring strategies for early detection.
