Olanzapine caused lysosome and autophagosome accumulation in mHypoA-59 neurons in a dose-dependent manner under serum-starved conditions. (A–C) mHypoA-59 neurons were incubated for 24hrs with and without 100 µM olanzapine under serum and serum-starved conditions. After staining with acridine orange (AO), quantification of acidic vesicles were determined as an increase in red (FL3) vs. green (FL1) using flow cytometry (A,B). Flow cytometric assessment of FL3 intensity (C). Respective images of A-B using a live-cell imager. (D,E) mHypoA-59 neurons were incubated for 24 h with or without 100 µM olanzapine under serum and serum-starved conditions. After staining with Cyto-ID, autophagosomes were quantified measuring an increase in green fluorescence (FL1) using flow cytometry (** p < 0.01, ***p < 0.001 compared to the serum only group). (F) mHypoA-59 neurons were incubated for 24hrs with and without 100 µM olanzapine under serum-starved conditions, LC3B-II and p62 were assessed via immunoblotting (* p < 0.05, ***p < 0.001 compared to the serum only group, data is presented as mean ± SEM) Abbreviations: Ola: Olanzapine.
