RelevanceThe hypothalamus acts as a major regulatory center involved in the control of feeding behavior and energy homeostasis. Several neuropeptides and proteins have been shown to be involved in the regulation of these processes. Orexin A (hypocretin 1) a 33 amino acid peptide and orexin B(hypocretin 2), a 28 amino acid peptide, are both derived from a common 130 amino acid precursor, prepro-orexin, which is encoded by a gene localized to human chromosome 17q21. Orexin A and Orexin B stimulate food consumption when administered intracerebroventricularly to rats. Orexin gene expression in the brain is highly restricted to distinct populations of neurons located in specific hypothalamic regions, including the lateral hypothalamic area (LHA), a region implicated in feeding behavior.
Cellular localizationAssociated with perikaryal rough endoplasmic reticulum as well as cytoplasmic large granular vesicles at synapses.
Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-Orexin B antibody [MM0501-5G21] (ab89888)
Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) analysis of human placental tissue section (4µm) labelling Orexin B with ab89888. Tissue was treated with 15µg/ml Protenase K for antigen retrieval and fixed with 4% PFA. A HRP-conjugated anti-mouse IgG was used as the secondary antibody (30 minutes at room temperature) followed by DAB color development.
