Hot Off the Press – October 25, 2018. There are currently no effective medications available for the treatment of psychostimulant addiction. Receptor-type protein tyrosine phosphatase D (PTPRD) is a neuronal cell-adhesion molecule that has been associated with psychostimulant addiction in humans. In this research, we found that PTPRD gene mutation significantly reduced vulnerability to cocaine… [Read More]

Distinct and Dynamic ON and OFF Neural Ensembles in the Prefrontal Cortex Code Social Exploration.
Hot Off the Press – October 10, 2018. Using miniature fluorescence microscopes (miniScope) via an implanted optical microprobe, Liang and Zhang et. al. were able to record the calcium activity from hundreds of nerve cells in medial prefrontal cortex (mPFC) when the mice freely engaged in social exploration. They track the activity of the same… [Read More]
The novel ghrelin receptor inverse agonist PF-5190457 administered with alcohol: preclinical safety experiments and a phase 1b human laboratory study.
Featured Paper of the Month – October 2018
Published in Molecular Psychiatry by Lee, Mary R; Tapocik, Jenica D; Ghareeb, Mwlod; Schwandt, Melanie L; Dias, Alexandra A; Le, April N; Cobbina, Enoch; Farinelli, Lisa A; Bouhlal, Sofia; Farokhnia, Mehdi; Heilig, Markus; Akhlaghi, Fatemeh; Leggio, Lorenzo
Understanding the neurobiological substrates of excessive alcohol consumption may substantially facilitate efforts to develop better treatments. The cross-talk between the gastrointestinal and central nervous systems, often referred to as the gut–brain axis, is a promising yet underexplored domain in this regard. Ghrelin is a hormone primarily produced by the stomach and known for its role in increasing appetite and food intake (the “hunger hormone”). Recent animal and human studies suggest that ghrelin may also be involved in alcohol-seeking behaviors. In rodent experiments, blocking the ghrelin receptor suppresses alcohol seeking and consumption…

Selective Activation of Striatal NGF-TrkA/p75NTR/ MAPK Intracellular Signaling in Rats That Show Suppression of Methamphetamine Intake 30 Days following Drug Abstinence
Featured Paper of the Month – September 2018
Published in Neuropsychopharmacology by Torres, Oscar V; Jayanthi, Subramaniam; McCoy, Michael T; Cadet, Jean Lud
Methamphetamine addiction is a public health threat throughout the world. Investigators in Dr. Cadet’s laboratory in the intramural program have developed a rat model of methamphetamine addiction that includes one of the psychiatric criteria used to make that diagnosis in humans. In that model, they used footshocks to represent adverse consequences that are present during the clinical course of addiction. Contingent footshocks helped the investigators to identify some rats (addicted) that continue to press a lever to get methamphetamine whereas other rats (non-addicted) suppress or stop their taking of methamphetamine in the presence of these adverse consequences…
Cannabinoid disruption of learning mechanisms involved in reward processing
Reviews To Read – August 28, 2018. The increasing use of marijuana, its derivatives, and synthetic cannabinoids for medicinal and recreational purposes has increased interest in understanding the addictive potential of this class of molecules. Studies show that nearly 1 in 10 marijuana users will eventually show signs of dependence on the drug, which is… [Read More]
