Abstract: Relapse to drug use during abstinence is a defining feature of addiction. During the last several decades, this clinical scenario has been studied at the preclinical level using classical relapse/reinstatement models in which drug seeking is assessed after experimenter-imposed homecage forced abstinence or extinction of the drug-reinforced responding in the self-administration chambers. To date, however, results from studies using the traditional rat relapse/reinstatement models have yet to result in FDA-approved medications for relapse prevention. The reasons for this state-of-affairs are complex and multi-faceted, but one potential reason is that in humans, abstinence is often voluntary and occurs either because the negative consequences of drug use outweigh the drug’s rewarding effects or the availability of nondrug alternative rewards that are chosen over the drug. Based on these considerations, we have developed rat models of relapse after voluntary abstinence, achieved either by introducing adverse consequences to drug taking (punishment) or seeking (electric barrier), or by providing mutually exclusive choices between the self-administered drug versus non-drug rewards (palatable food or social interaction). In the lecture, I will provide an overview of these new relapse models and present recent neurobiological findings from studies using these models.  

Biography: Yavin Shaham received his BS and MA from the Hebrew U, Jerusalem, and his PhD from the Uniformed Services University of the Health Sciences, Bethesda, MD. His postdoctoral training was at Concordia U, Montreal, in the laboratory of Dr. Jane Stewart. Prior to joining the NIDA Intramural Research Program, he was an investigator at the Addiction Research Center, Toronto. He is currently a tenured Branch Chief and a Senior Investigator. His major awards include Society of Neuroscience Jacob Waletzky award for innovative research in drug and alcohol addiction (2006), NARSAD Distinguished Investigator Grant Award (2016), NIDA-IRP Investigator Mentoring Award (2016), European Behavioral Pharmacology Society (EBPS) Distinguished Achievement Award (2017), the NIH Director’s Award of Merit (2020), and the NIH Ruth Kirschstein Mentoring Award (2022). Most recently, he was invited to present his research at a 2023 Nobel symposium entitled the ‘Social Brain. ‘He has published over 240 empirical papers, reviews, and commentaries, and his papers were cited over 37,500 times (h-factor: 104; Google Scholar). In 2018, Shaham was named by The Web of Science as a “Highly Cited Researcher” (top 1%). He has served as a Reviewing and Senior Editor of The Journal of Neuroscience from 2008 to 2018 and currently severs as a Reviewing Editor of Neuropsychopharmacology and as an Advisory Board Member of eNeuro. He is also an editorial board member of Biological Psychiatry, Psychopharmacology, Behavioural Pharmacology, and Addiction Biology. Shaham currently serves as the president of EBPS. His group investigates mechanisms of relapse to opioid and psychostimulant seeking, as assessed in rat models developed in his lab (https://irp.drugabuse.gov/organization/bnrb/nrs/).
