Apoptosis and p75 processing are increased in neuronal cultures from APP/PS1 animals. Primary cultures of differentiated mouse hippocampal NSCs were treated for 6 days (7DIV) with MGO modified BSA (MBSA) or with MGO modified proBDNF (MproBDNF). a) Representative immunofluorescence pictures of cells from WT and APP/P1 mice labeled with ICDp75 (green), βIIItubulin (red) and DAPI (white). Inset represents a higher magnification image of the boxed areas indicating citoplasmatic (WT) and nuclear localization (APP/PS1) of ICDp75. b) Bars represent the quantification of apoptosis (by nuclei morphology), expressed as the mean of % apoptosis ± SD of the positive cells for both ICDp75 and βIIItubulin. c) Bars represent the mean of the % ± SD of neurons with the ICDp75 translocated to the nuclei (% ICD nuclear). The values represent the mean of three independent experiments Scale bar =50 μm . ** p < 0,01, two tailed Student’s “t” test
