Abstract Rationale: Co-users of alcohol and nicotine are the largest group of polysubstance users worldwide. Commonalities in mechanisms of action for ethanol (EtOH) and nicotine proposes the possibility of developing a single pharmacotherapeutic to treat co-use. Objectives: Toward developing a preclinical model of co-use, female alcohol-preferring (P) rats were trained for voluntary EtOH drinking and i.v. nicotine self-administration in three phases: (1) EtOH alone (0 vs. 15%, 2-bottle choice); (2) nicotine alone (0.03 mg/kg/infusion, active vs. -
Neuronal Nicotinic Receptors: from Structure to Pathology

Clementi* CNR, Institute of Neuroscience, Cellular and Molecular Pharmacology Section, Department of Medical Pharmacology and Center of Excellence on Neurodegenerative Diseases, University of Milan, Via Vanvitelli 32, 20129 Milan, Italy Received 22 July 2004; accepted 29 September 2004 Available online 27 October 2004 Abstract Neuronal nicotinic receptors (NAChRs) form a heterogeneous family of ion channels that are differently expressed in many regions of the central nervous system (CNS) and peripheral nervous system. These different receptor subtypes, which have characteristic pharmacological and biophysical properties, have a pentameric structure consisting of the homomeric or heteromeric combination of 12 different subunits (a2–a10, b2–b4). By responding to the endogenous neurotransmitter acetylcholine, NAChRs contribute to a wide range of brain activities and influence a number of physiological functions. Furthermore, it is becoming evident that the perturbation of cholinergic nicotinic neurotransmission can lead to various diseases involving nAChR dysfunction during development, adulthood and ageing. In recent years, it has been discovered that NAChRs are present in a number of non-neuronal cells where they play a significant functional role and are the pathogenetic targets in several diseases. NAChRs are also the target of natural ligands and toxins including nicotine (Nic), the most widespread drug of abuse. This review will attempt to survey the major achievements reached in the study of the structure and function of NAChRs by examining their regional and cellular localisation and the molecular basis of their functional diversity mainly in pharmacological and biochemical terms. -

Treating Smoking Dependence in Depressed Alcoholics
Treating Smoking Dependence in Depressed Alcoholics Nassima Ait-Daoud, M.D.; Wendy J. Lynch, Ph.D.; J. Kim Penberthy, Ph.D.; Alison B. Breland, Ph.D.; Gabrielle R. Marzani-Nissen, M.D.; and Bankole A. Johnson, D.Sc., M.D., Ph.D. Alcoholism and nicotine dependence share many neurobiological underpinnings; the presence of one drug can cause a person to crave the other. Depressive illness can complicate comorbid alcohol and nicotine dependence by exacerbating the negative affect encountered during attempts to abstain from one or both drugs. Given the morbidity and mortality associated with cigarette smoking, it is imperative to identify treatments to promote smoking cessation and address comorbid psychiatric conditions contemporaneously. Pharmacotherapeutic options demonstrating varying degrees of efficacy and promise in preclinical and clinical studies include nicotine replacement therapy (NRT), selective serotonin reuptake inhibitors (SSRIs), bupropion, varenicline, tricyclic antidepressants, and bupropion plus NRT. Topiramate has shown potential for promoting smoking cessation in alcoholics, although its safety in depressed patients has not been fully explored. The efficacy of medications for treating nicotine dependence is generally enhanced by the inclusion of behavioral interventions such as cognitive behavioral therapy. When group cohesion and social support are stressed, success rates increase among depressed smokers undergoing smoking cessation treatment. Additional treatment strategies targeting dually dependent individuals with -
Differing Time Dependencies of Object Recognition Memory Impairments Produced by Nicotinic and Muscarinic Cholinergic Antagonism in Perirhinal Cortex
Downloaded from learnmem.cshlp.org on September 24, 2021 - Published by Cold Spring Harbor Laboratory Press Research Differing time dependencies of object recognition memory impairments produced by nicotinic and muscarinic cholinergic antagonism in perirhinal cortex Chris J. Tinsley,1,3 Nadine S. Fontaine-Palmer,1 Maria Vincent,1 Emma P.E. Endean,1 John P. Aggleton,2 Malcolm W. Brown,1 and E. Clea Warburton1 1MRC Centre for Synaptic Plasticity, School of Physiological Sciences, Bristol University, Bristol BS8 1TD, United Kingdom; 2School of Psychology, Cardiff University, Cardiff CF10 3AT, United Kingdom The roles of muscarinic and nicotinic cholinergic receptors in perirhinal cortex in object recognition memory were com- pared. Rats’ discrimination of a novel object preference test (NOP) test was measured after either systemic or local infusion into the perirhinal cortex of the nicotinic receptor antagonist methyllycaconitine (MLA), which targets alpha-7 (a7) amongst other nicotinic receptors or the muscarinic receptor antagonists scopolamine, AFDX-384, and pirenzepine. Methyllycaconitine administered systemically or intraperirhinally before acquisition impaired recognition memory tested after a 24-h, but not a 20-min delay. In contrast, all three muscarinic antagonists produced a similar, unusual pattern of impairment with amnesia after a 20-min delay, but remembrance after a 24-h delay. Thus, the amnesic effects of nicotinic and muscarinic antagonism were doubly dissociated across the 20-min and 24-h delays. The same pattern of shorter-term but not longer-term memory impairment was found for scopolamine whether the object preference test was carried out in a square arena or a Y-maze and whether rats of the Dark Agouti or Lister-hooded strains were used. -
