Figure Lengend Snippet: Activation time course of VTA DA neurons after social approach test. (A) Left: Schematic diagram of the social approach test. Two groups of mice (object vs. social) were allowed to freely interact with either a social conspecific or an object, respectively, for 10 min followed by transcardiac perfusion at different time points. Right: Mice in the social group spent significantly more time interacting with the target compared with that of mice in the object group. (B) Left: Representative images showing the activation of DA neurons in the VTA by co-immunofluorescent staining with Tyrosine hydroxylase (TH, red) and c-fos (green). Bar: 25 μm. Right: Quantification of the total number of activated cells (c-fos + ), activated DA neurons (TH + c-fos + ), and the percentage of activated DA neurons. Each group contained 12 sections from 3 mice for all six groups. * p < 0.05, ** p < 0.01, *** p < 0.001, **** p < 0.0001 compared with object; ### p < .0.001 compared with 1.5 h. Data are presented with mean ± S.E.M.
Article Snippet: For immunofluorescent staining, the sections were blocked in blocking buffer (1% BSA, 3% donkey serum, and 0.3% Triton X-100 in phosphate-buffered saline) for 1 h at room temperature and incubated with mouse anti-tyrosine hydroxylase (TH) primary antibody (1:400, #MAB318, Millipore, Temecula, CA, USA) and rabbit anti-c-fos primary antibody (1:400, #2250, Cell Signaling Technology, Danvers, MA, USA) overnight at 4°C.
