Intracellular TAPP fluorescence and colocalization. LM3 cells were exposed to 5 μM TAPP for 5 min, 30 min and 180 min, and red fluorescence was visualized by fluorescence microscopy (a). Cells exposed to TAPP for 180 min (red fluorescence) were then incubated with Lysotracker Green®, Mitotracker Green®, or NBD C6-Ceramide (green fluorescence) (b). Magnification 100X. These micrographs were representative of those obtained from three independent experiments
