SSTR3 and MCHR1 receptors in primary cilia of select brain regions. (A) In the paraventricular hypothalamus region of the WT mouse brain, MCHR1 is seen concentrated in the neuronal cilia (red). (B) In the ventromedial hypothalamus region of the WT mouse brain, SSTR3 (green) is present in the neuronal primary cilia, thus validating the antibodies and the presence of these GPCRs in the cilia. Cell nuclei were counter stained blue by DAPI.
