The neurokinin 1 (NK1) receptor is a member of the tachykinin family of G-protein-coupled receptors which also includes NK2 and NK3 receptors. The NK1 receptor is localized in high concentrations in the CNS (particularly the striatum, amygdala and some hypothalamic and thalamic nuclei) and peripheral tissues.
NK1 receptors are thought to mediate central stress reactions, mood control, excitatory neurotransmission, immune modulation and airway and lung function. The receptor displays greater potency for the endogenous agonist substance P than Neurokinin A and Neurokinin B (SP > NKA > NKB). The human gene encoding the NK1 receptor has been localized on chromosome 2 (2p13.1-p12).View all products for NK1 Receptors »

Peptides Involved in Appetite Modulation Review
Written by Sonia Tucci, Lynsay Kobelis and Tim Kirkham, this review provides a synopsis of the increasing number of peptides that have been implicated in appetite regulation and energy homeostasis; putative roles of the major peptides are outlined and compounds available from Tocris are listed.
Review excerpt: "The appetite-stimulatory circuit expresses orexigenic neurotransmitters which promote appetite, while anorexigenic neurotransmitters released by the inhibitory circuit reduce appetite. In addition to modulation by signals originating in the periphery, these integrative functions are affected by a wide range of neural influences within the brain, reflecting sensory, cognitive, memory and affective processes."Request copy | Download PDF
Written by Janet Maguire and Anthony Davenport, this poster summarizes different GPCR classes of the vascular system and their cognate ligands. The predominant vasoactive response of blood vessels to specific receptor activation is also described. Endogenous ligands and Tocris compounds are listed.Request copy | View all posters
