Alpha-Conotoxins, peptides produced by predatory species of Conus marine snails, are potent antagonists of nicotinic acetylcholine receptors (nAChRs), ligand-gated ion channels involved in synaptic transmission. We determined the NMR solution structure of the smallest known alpha-conotoxin, ImI, a 12 amino acid peptide that binds specifically to neuronal(More)
The Eating Disorder Inventory (EDI; Garner, Olmsted, & Polivy, 1983) is used as a screening instrument for identifying potential anorexia nervosa and bulimia nervosa. It comprises eight subscales: Bulimia, Drive for Thinness, Body Dissatisfaction, Maturity Fears, Introceptive Awareness, Perfectionism, Interpersonal Distrust, and Ineffectiveness. We examined(More)
alpha-Conotoxins are small disulfide-constrained peptide toxins which act as antagonists at specific subtypes of nicotinic acetylcholine receptors (nACh receptors). In this study, we analyzed the structures and activities of three mutants of alpha-conotoxin ImI, a 12 amino acid peptide active at alpha7 nACh receptors, in order to gain insight into the(More)
Tachykinins (TKs) are a family of neurotransmitters that function as signaling molecules for such processes as maintaining homeostasis, regulating stress response, and modulating pain. TKs require the expression of at least one of three receptor subtypes: Neurokinin Receptor-1 (NKR-1), Neurokinin Receptor-2 (NKR-2), or Neurokinin Receptor-3 (NKR-3). We have(More)
