Figure 6.
Morphology of GFP-Nter-TIVAMP–expressing cells. PC12 cells transfected with GFP-Nter-TIVAMP and treated with staurosporine as in Fig. 5 were fixed, processed for double fluorescence by combining direct GFP fluorescence detection with indirect immunofluorescence detection using the indicated antibodies. Representative GFP-Nter-TIVAMP–transfected cells without or with short neurite(s) are shown in horizontal confocal sections. Syntaxin (Stx) 1 and 6 and synaptobrevin 2 (Sb2) have a localization similar in untransfected as in GFP-Nter-TIVAMP–expressing cells. Synaptotagmin I immunoreactivity was weaker in GFP-Nter-TIVAMP–transfected cells than in untransfected cells. Bar, 10 μm.
