FIG. 2.

Analysis of GIPR expression in spinal cords of control groups. Representative images of GIPR immunostaining in spinal cord of naïve (A) or sham-operated (B) animals; gray matter is delimitated by dashed lines, with white matter on the surroundings. (C and D) Magnified images of the gray matter show moderate staining in cells morphologically compatible with neurons. (E and F) Magnified images of areas highlighted in C and D, where it is possible to observe the cytoplasmic staining for GIPR. GIPR, glucose-dependent insulinotropic peptide receptor. (A, B original magnification 20×; C, D original magnification 100×; E, F original magnification 400×.)
