We are very grateful to C. Pestourie and the Non-Invasive Exploration service (US006/CREFRE INSERM/UPS) for the use of the γ-irradiator facility, and to L. Debrauwer and E. Jamin (Axiom facility, Metatoul, INRA) for providing the Orbitrap mass spectrometer.

Graphical Abstract

Copper-amyloid-β ROS production: Copper ions (red sphere, see picture) have been found to accumulate in amyloid-β plaques and play a role in the generation of reactive oxygen species (ROS) within this context. Mass spectrometry studies were able to detail the sites of oxidation damage and shed new light on the mechanism of ROS production, important for the understanding of the pathogenicity of amyloid-β peptides.
