APP is abundantly expressed in nuclei of the Central Autonomic System (CAS). Immunohistochemical staining for APP reveals high levels of expression in the Bed Nucleus of the Stria Terminalis (BST; A), Amygdala (LA-lateral, BLA-Basolateral, CeA-Central, MeA-Medial, B), Paraventricular Nucleus of the Hypothalamus (PVN; C), , Locus Coereleus (LC) and Parabrachial Nucleus (PB; D), and the nucleus of the Solitary Tract (NTS; E). (F) Lack of staining in a section of the PVN from an APP null mutant (APP−/−) demonstrates the specificity of the antibody used against APP. A (G, H, I) Staining of human amygdala sections for APP reveals prominent staining in the Basolateral (G), Cortical (H) and Central (I) nuclei. Scale Bar: A–F = 200μm; G-I = 100μm
