Our faculty colleague, Dr. Benjamin Siemsen, has published a new paper: A Subset of Nucleus Accumbens Neurons Receiving Dense and Functional Prelimbic Cortical Input Are Required for Cocaine Seeking. Front. Cell. Neurosci., 24 February 2022.

We welcome Dr. Melanie Pina who joined our department in January 2022 as Assistant Professor. Dr. Pina received her PhD in Behavioral Neuroscience from Oregon Health & Science University in 2016. Her postdoctoral work was done in Dr. Tom Kash’s lab in the Department of Pharmacology at UNC- Chapel Hill. Her lab’s research at UMB will focus on identifying the distinct neural circuits and signaling mechanisms that regulate excessive drug use and determining how plasticity within these systems can contribute to comorbid neuropsychiatric conditions. Dr. Pina’s lab integrates behavioral models with electrophysiological, biochemical, and genetic approaches to identify the molecular and cellular adaptations that occur in the brain following repeated exposure to alcohol and other drugs of abuse. Dr. Pina is especially interested in how disrupted serotonin signaling can drive aggression and contribute to the development of anxiety and depression-like behavior.

A new publication from Dr. Marco Venniro's lab, describes the adaptation to the mouse of his novel model of volitional social interactions. Waving through the window: a model of volitional social interaction in female mice, Biol. Psychiatry, Nov. 9, 2021.

The latest paper from Dr. Michy Kelly's group in Front. Pharmacol. is titled The Role of PDE11A4 in Social Isolation-Induced Changes in Intracellular Signaling and Neuroinflammation. It suggests that social isolation-induced decreases in hippocampal PDE11A4 may alter subsequent social behavior in adult mice (but not adolescent mice) by altering neuroinflammatory processes (i.e., IL-6 and microglia), was published Nov. 23, 2021

Dr. Marco Venniro and Research Assistant Kimberly Papastrat,were among the co-authors of “Factors Modulating the Incubation of Drug and Non-Drug Craving and their Clinical Implications,” which was published in Neuroscience & Biobehavioral Reviews on September 28, 2021. 

Dr. Iris Lindberg, coauthored an invited mini-review on “Obesity, POMC, and POMC-processing Enzymes: Surprising Results From Animal Models,” which was published in the December 2021 issue of Endocrinology.

The newest research from Dr. Michy Kelly and colleagues suggests the hippocampus, a brain region critical for memory storage, is particularly vulnerable to increased inflammation during aging (Published in Journal of Neuroinflammation, September 2021). Increased inflammation was also observed in other brain regions, but not nearly as widespread as in the hippocampus. Interestingly, this effect was more pronounced in females than males, possibly explaining why females display faster age-related cognitive decline than men and higher rates of Alzheimer’s disease. Together, this work points to cytokine signaling as a therapeutic target in the fight against age-related cognitive decline.

Dr. Cali Calarco, Postdoctoral Fellow, in Dr. Mary Kay Lobo's lab, received a partial year, $44,260, Postdoctoral National Research Service Award from the National Institute of Drug Abuse (NIH/NIDA) to study “The Influence of Peroxisome Proliferator-Activated Receptor Gamma Coactivator - 1 Alpha (PGC-1a) on the Nucleus Accumbens During Cocaine-Self-Administration.” Dr. Joseph Cheer is co-sponsor.

Dr. Marco Venniro, was selected as a Travel Awardee for the 2021 American College of Neuropsychopharmacology (ACNP) 60th Annual Meeting which will be held in San Juan, Puerto Rico, December 5-8, 2021.

Benjamin Siemsen, PhD, joined the Department as a Faculty Research Associate July 19th, 2021. Dr. Siemsen completed his Ph.D. in 2018 at the Medical University of South Carolina and stayed at MUSC to conduct his post-doctoral fellowship from 2018-2021.

Social support promotes abstinence from abused drugs for many, but not all, people with addiction to drugs. In a new Neuropsychopharmacology paper, Dr. Venniro and colleagues used a rat model designed to mimic features of the community-reinforcement approach to show that immediate voluntary social reward inhibits cocaine self-administration and prevents the intensification of cocaine seeking over periods of abstinence. These effects are independent of cocaine self-administration access condition and sex. Additionally, parametric manipulations of the social versus cocaine choice reveals the rats’ differing propensities to resume cocaine seeking when social reward is delayed or more effortful. These individual differences might identify a subset of rats comparable to the subset of people who do not respond well to socially based treatments. Such rats might be a suitably stringent testing ground for new pharmacological/biomedical treatments.

The latest paper from Dr. Michy Kelly's lab, published in Molecular Psychiatry, July 28, 2021, suggests there may be a genetic basis for friendship. They show that mice prefer to interact with other mice that express the exact same version of an enzyme called PDE11A—even a single amino acid difference in this enzyme is enough to shift social preferences of mice. The ability to predict mutual social preferences could have wide-ranging impacts, including lowering divorce rates, improving healthcare (i.e., predicting patient-provider compatibility), or developing treatments for disorders associated with social avoidance/withdrawal. The paper was featured on NBC News, the NY Post, LabRoots, and several other outlets.

Dr. Sara Keefer, Postdoctoral Fellow in the lab of Dr. Donna Calu, received the 2021 Michael Shipley Postdoctoral Award.

In a new paper, Drs. Olga Bocharova, Ilia Baskakov and their colleagues dispute the hypothesis that Aβ peptides, which are associated with Alzheimer’s disease, have antiviral effects and are produced by the CNS as an innate defense mechanism. The paper demonstrates that regardless of the strain or dose of the virus, animal sex or age, Aβ peptide does not protect the CNS against infection with Herpes Simplex Virus 1. The paper was selected for JBC Editors' Pick and covered by ALZFORUM.ORG

This latest paper from the Cheer lab published in the J. of  Neuroscience provides evidence that pharmacologically raising tissue levels of endogenous cannabinoids, is a safe, non-desensitizing way to maintain levels of motivation for psychiatric  conditions characterized by compromised motivational levels. Importantly, this strategy is devoid of dependence liability.

The Lindberg lab's new paper describes a new inducible mouse model of processing enzyme insufficiency which is restricted to POMC-expressing cells. While it was previously thought that loss of the processing enzyme PC1/3 in POMC-expressing cells would explain the known association of PC1/3 mutations with obesity, we found that our mice were not obese. Thus non-POMC-related mechanisms for explaining the strong obesity risk associated with human PC1/3 mutations humans must now be sought. Postdoc Dr. Manita Shakya is first author. Endocrinology, March 2021. The paper was selected as a featured article. The authors were invited to submit a mini-review on Obesity, POMC and POMC-processing enzymes based on the article.

In a new paper, Dr. Mary Kay Lobo and her colleagues (including co-first authors Drs. Shannon Cole and Ramesh Chandra) demonstrate that cocaine exposure impacts mitochondrial dynamics and morphology by regulating mitochondria-related nuclear gene transcripts, to affect neuronal function and plasticity.
"Cocaine induced neuron subtype mitochondrial dynamics through Egr3 transcriptional regulation."
