It is therefore critical to understand how A\u03b2 pathology is initiated and where and when distinct A\u03b2 species aggregate. Here, we used metabolic isotope labeling in APP knock-in mice together with mass spectrometry imaging to monitor the earliest seeds of A\u03b2 deposition through ongoing plaque development. This allowed visualizing A\u03b2 aggregation dynamics within single plaques across different brain regions. We show that formation of structurally distinct plaques is associated with differential A\u03b2 peptide deposition. Specifically, A\u03b21-42 is forming an initial core structure followed by radial outgrowth and late secretion and deposition of A\u03b21-38. These data describe a detailed picture of the earliest events of precipitating amyloid pathology at scales not previously possible.NL-G-F", "doi": "10.1126/sciadv.abg4855", "pmid": "34134980", "labels": {"Integrated Microscopy Technologies Gothenburg": "Collaborative"}, "xrefs": [{"db": "pmc", "key": "PMC8208724"}, {"db": "pii", "key": "7/25/eabg4855"}], "notes": [], "created": "2023-02-16T08:19:47.219Z", "modified": "2023-02-16T08:19:47.531Z"}
