GTN increases the expression the of Y1 receptor in the MHb, but not affects the Y2 receptor. A and B Left: representative images of Y1 receptor (A, green), Y2 receptor (B, green), and DAPI (blue) immunofluorescence of VEH and GTN mice. (scale bars: 100 μm for overviews; 10 μm for zooms). Right: mean fluorescence intensity of Y1 receptor (A) and Y2 receptor (B) in the GTN group relative to the VEH group. n = 4 mice per group, six sections per mouse. Significance was assessed by a two-tailed unpaired Student’s t-test. All data are presented as the mean ± S.E.M. **P < 0.01
