New G2B REVIEWS Issue
The focus of the new 2017 issue of G2B REVIEWS is Drug Addiction. Drug addictions are serious medical conditions that have genetic and neurobiological correlates that remain elusive, but which are subject of intense investigation. This issue of G2B REVIEWS presents a dozen articles on the latest breakthroughs in drug addiction from some of the leaders in the field. Access the entire issue for free: click here

This review discusses recent findings on the functional role of D2Rs and highlights the distinctive contributions of D2Rs expressed on specific neuronal subpopulations to the behavioral responses to stimulant drugs. A circuit-wide restructuring of local and long-range inhibitory connectivity within the basal ganglia is observed in response to manipulation of striatal D2R levels and is accompanied by multiple alterations in dopamine- dependent behaviors. These findings from animal models have deep clinical implications for SUD patients with low levels D2R availability where a similar restructuring of basal ganglia circuitry is expected to take place.

In this study, we provide genetic and pharmacological evidence that proopiomelanocortin (POMC) within the hypothalamus plays an essential role in alcohol drinking and relapse. Using site-specific transgenic mouse model and pharmacological validation experiments, we show that POMC expressed in the hypothalamic neurons (but not pituitary cells) plays an important role in the alcohol deprivation effect (the increase in alcohol intake after a period of abstinence), with impact on ‘binge’-like and escalation drinking. Medications targeting hypothalamic POMC by selective alteration of the region- and cell-specific POMC might have therapeutic efficacy.
