Discovery of the day
Researchers developed a novel positron emission tomography (PET) imaging strategy to detect cerebral microthrombi in a mouse model of Alzheimer’s disease, using fibrin-binding and platelet-targeted radiotracers. The study demonstrated that cerebral fibrin burden measured by PET correlated with platelet content in post-mortem brain tissue from both transgenic mice and human Alzheimer’s patients, with uptake differentiating diseased from wild-type animals particularly with advancing age. For your work on multimodal biomarkers in neurodegenerative disease, this PET-based approach offers a new in vivo method to stratify Alzheimer’s patients by procoagulant status, providing a direct imaging correlate that could be integrated with clinical data and proteomic biomarkers to inform personalized therapeutic decisions.
