报告摘要:

Within the amyloid hypothesis in Alzheimer’s disease, current focus has shifted to earlier stage of amyloid beta (Aβ) peptide assembly, involving insoluble oligomers and small aggregates that are more toxic to cells compared to their morphological distinct fibril forms. Critical to the Aβ field is unlocking the molecular level kinetic pathways or mechanisms of oligomerization, leading to culprit subset or specific species of Aβ oligomer populations responsible for the disease etiology. Herein, we employ High-Speed AFM to directly “watching” and reveal single molecule dynamics at sub-molecular spatial resolution.
