MTNR1B immunostaining. (A) In the nucleus of the solitary tract of the medulla oblongata, mild, diffuse neuropil staining was observed and was stronger in the control animals than in the (B) scrapie-infected animals. (C) In the molecular layer of the cerebellar cortex, a strong signal was observed in the Purkinje cells and their dendrites (arrowheads). (D) This signal was reduced or absent in the scrapie-infected animals.
