Effect of the Novel Positive Allosteric Modulator of Metabotropic Glutamate Receptor 2 AZD8529 on Incubation of Methamphetamine Craving After Prolonged Voluntary Abstinence in a Rat Model
Featured Paper of the Month – March 2016
Published in Biological Psychiatry by Caprioli, Daniele; Venniro, Marco; Zeric, Tamara; Li, Xuan; Adhikary, Sweta; Madangopal, Rajtarun; Marchant, Nathan J; Lucantonio, Federica; Schoenbaum, Geoffrey; Bossert, Jennifer M; Shaham, Yavin
Cue-induced methamphetamine craving increases after prolonged forced (experimenter-imposed) abstinence from the drug (incubation of methamphetamine craving). Here, we determined whether this incubation phenomenon would occur under conditions that promote voluntary (self-imposed) abstinence…
Cocaine-Induced Endocannabinoid Mobilization in the Ventral Tegmental Area
Featured Paper of the Month – February 2016
Published in Cell Reports by Wang, Huikun; Treadway, Tyler; Covey, Daniel P; Cheer, Joseph F; Lupica, Carl R
Cocaine is a highly addictive drug that acts upon the brain’s reward circuitry via the inhibition of monoamine uptake. Endogenous cannabinoids (eCB) are lipid molecules released from midbrain dopamine (DA) neurons that modulate cocaine’s effects through poorly understood mechanisms…
High Affinity Dopamine D3 Receptor (D3R)-Selective Antagonists Attenuate Heroin Self-Administration in Wild-Type but not D3R Knockout Mice
Featured Paper of the Month – January 2016
Published in The Journal of Medical Chemistry by Boateng, Comfort A; Bakare, Oluyomi M; Zhan, Jia; Banala, Ashwini K; Burzynski, Caitlin; Pommier, Elie; Keck, Thomas M; Donthamsetti, Prashant; Javitch, Jonathan A; Rais, Rana; Slusher, Barbara S; Xi, Zheng-Xiong; Newman, Amy Hauck
The dopamine D3 receptor (D3R) is a promising target for the development of pharmacotherapeutics to treat substance use disorders. Several D3R-selective antagonists are effective in animal models of drug abuse, especially in models of relapse. Nevertheless, poor bioavailability, metabolic instability, and/or predicted toxicity have impeded success in translating these drug candidates to clinical use…

Structure-Activity Relationships of (+)-Naltrexone-Inspired Toll-like Receptor 4 (TLR4) Antagonists.
Featured Paper of the Month – December 2015
Published in The Journal of Medical Chemistry by Selfridge, Brandon R; Wang, Xiaohui; Zhang, Yingning; Yin, Hang; Grace, Peter M; Watkins, Linda R; Jacobson, Arthur E; Rice, Kenner C
Activation of Toll-like receptors has been linked to neuropathic pain and opioid dependence. (+)-Naltrexone acts as a Toll-like receptor 4 (TLR4) antagonist and has been shown to reverse neuropathic pain in rat studies. We designed and synthesized compounds based on (+)-naltrexone and (+)-noroxymorphone and evaluated their TLR4 antagonist activities by their effects on inhibiting lipopolysaccharide (LPS) induced TLR4 downstream nitric oxide (NO) production in microglia BV-2 cells…
Impaired functional connectivity within and between frontostriatal circuits and its association with compulsive drug use and trait impulsivity in cocaine addiction.
Featured Paper of the Month – November 2015
Published in JAMA Psychiatry by Hu, Yuzheng; Salmeron, Betty Jo; Gu, Hong; Stein, Elliot A; Yang, Yihong
Converging evidence has long identified both impulsivity and compulsivity as key psychological constructs in drug addiction. Although dysregulated striatal-cortical network interactions have been identified in cocaine addiction, the association between these brain networks and addiction is poorly understood…
Mechanism of the Association between Na+ Binding and Conformations at the Intracellular Gate in Neurotransmitter:Sodium Symporters.
Featured Paper of the Month – October 2015
Published in The Journal of Biological Chemistry by Stolzenberg, Sebastian; Quick, Matthias; Zhao, Chunfeng; Gotfryd, Kamil; Khelashvili, George; Gether, Ulrik; Loland, Claus J; Javitch, Jonathan A; Noskov, Sergei; Weinstein, Harel; Shi, Lei
Neurotransmitter:sodium symporters (NSSs) terminate neurotransmission by Na(+)-dependent reuptake of released neurotransmitters. Previous studies suggested that Na(+)-binding reconfigures dynamically coupled structural elements in an allosteric interaction network (AIN) responsible for function-related conformational changes, but the intramolecular pathway of this mechanism has remained uncharted…
