PYY-immunoreactive (ir) fibers are present in NTS, 10N, and 12N regions of the hindbrain. DVC, dorsal vagal complex; NTS, nucleus of the solitary tract; 10N, dorsal motor nucleus of the vagus; 12N, hypoglossal nucleus; Bregma, 7.08–7.64 mm. A and B: representative IHC images using PYY antibody showing the presence of PYY-ir projections in DVC and 12N regions. C and D: high magnification images of squared areas in A and B, respectively. E and F: high magnification confocal images of squared areas in C and D, respectively.
