Immunolocalization of Aβ in AVs from L/APP cells and PS1/APP brains and γ-secretase components (PS1 and nicastrin) in L/APP cells. Immunogold localization of Aβ40 (A), Aβ42 (B), PS1 (C), nicastrin (D), and in the absence of primary antibody (E) in L/APP cells grown for 6 h in the absence of Leu and His. (F) Quantification of gold particle frequency in AV or tubulovesicular compartments (TBV), which comprise 27.0 ± 11.0 and 19.2 ± 7.2%, respectively, of the total cell area. Error bars represent SEM. (G and H) IEM followed by silver stain enhancement for Aβ40 was performed in 9-mo-old PS1/APP mice.
