Depiction of cell treatment models. iPSC-derived neurons are first differentiated for 60 days, then treated with 1 µM oligomeric amyloid-beta for 24 h. Neurons are collected and used for Western blot, or with nLC-MS/MS (whole proteome analysis and phosphoenrichment). Quantification is performed by densitometry (Western blot) and by label-free quantification (LFQ) using Scaffold proteomics software. Fold-change values were compared between both methods to validate the LFQ method.
