Study targets kappa opioid receptor to develop more effective drugs for pain management (Links to an external site)

In a study published in Nature Communications in March 2023, researchers from the Center for Clinical Pharmacology unveil promising research in the development of more effective, less addictive, and safer pain management drugs.
In this study “Molecular mechanism of biased signaling at the kappa opioid receptor,” researchers closely examined the κ-opioid receptor (KOR), a molecule in the body that can be targeted by drugs to help manage pain and itch without causing addiction.

Elgendy and Hegazy Receive $3.1 Million NIH Grant to Support Chronic Pain Research (Links to an external site)

Bahaa Elgendy, Ph.D., associate professor of medicinal chemistry at University of Health Sciences and Pharmacy in St. Louis and Lamees Hegazy, Ph.D., associate professor of computational and medicinal chemistry at UHSP, were the recent recipients of a $3.1 million grant from the National Institutes of Health’s National Institute of Neurological Disorders and Stroke to support research focused on the treatment of inflammatory pain.

The five-year grant will allow Elgendy and Hegazy, and their research collaborators, to further investigate the role of the REV-ERB nuclear receptors as a viable target for the treatment of inflammatory pain. Elgendy and Hegazy will leverage the known physiological functions of REV-ERB in chronic inflammation and use a chemical biology approach to identify novel REV-ERV ligands with superior pharmacological profiles, with the goal of advancing the potential therapy to clinical trials.

Al-Hasani Uncovers New Avenues to Treat Pain and Addiction (Links to an external site)

In 2017, Ream Al-Hasani, Ph.D., assistant professor of pharmaceutical science at University of Health Sciences and Pharmacy in St. Louis, and assistant professor of anesthesiology at Washington University School of Medicine in St. Louis, was recruited as one of the first researchers at the Center for Clinical Pharmacology. Since then, Al-Hasani and her center collaborators from the Department of Anesthesiology at the School of Medicine have been conducting groundbreaking research on the neurological effects of addiction and the brain’s response to pain or stress.
With much of her research focused on the kappa opioid receptor system and its potential to serve as a promising target for the non-addictive management of neuropsychiatric conditions, including pain, Al-Hasani has been engaged in a number of innovative projects, including her work to create new methods for measuring opioid peptides in living systems. Her efforts have resulted in the development of a reliable and reproducible process to allow other research labs to implement and benefit from this technique.

Scientists Develop Wireless-Networks that Allow Brain Circuits to Be Studied Remotely using the Internet (Links to an external site)

In a recent study published in Nature Biomedical Engineering on November 25, 2021, Jordan McCall, PhD, MPH, alongside Jae-Woong Jeong, PhD, at Korea Advanced Institute of Science and Technology (KAIST), and Sangtae Ha, PhD, at the University of Colorado, Boulder, have developed a method to remotely control brain circuits in multiple animals simultaneously and independently.
By creating a wireless network utilizing implantable devices and equipment integrated with Internet of Things (IoT) technology, scientists have enabled leading-edge, large-scale neuroscience experiments that can study the brains of animals from almost anywhere outside of the lab. The low-cost setup of this system means it can be easily adopted by other labs due to its minimalistic hardware, ease of use, and customizability. Scientists will be able to implement this technology in their existing laboratories with minimal budget concerns to achieve remote access and automate experiments where having a human present could affect the outcomes of the study.

Non-alcoholic fatty liver disease (NAFLD) affects a significant number of people worldwide and currently there are no pharmacological treatments. NAFLD often presents with obesity, insulin resistance, and in some cases cardiovascular diseases. There is a clear need for treatment options to alleviate this disease since it often progresses to much more the much more severe non-alcoholic steatohepatitis (NASH). The REV-ERB nuclear receptor is a transcriptional repressor that regulates physiological processes involved in the development of NAFLD including lipogenesis and inflammation. We hypothesized that pharmacologically activating REV-ERB would suppress the progression of fatty liver in a mouse model of NASH. Using REV-ERB agonist SR9009 in a mouse NASH model, we demonstrate the beneficial effects of REV-ERB activation that led to an overall improvement of hepatic health by suppressing hepatic fibrosis and inflammatory response.

Nociceptin and its receptor are widely distributed throughout the brain in regions associated with reward behavior, yet how and when they act is unknown. Here, we dissected the role of a nociceptin peptide circuit in reward seeking. We generated a prepronociceptin (Pnoc)-Cre mouse line that revealed a unique subpopulation of paranigral ventral tegmental area (pnVTA) neurons enriched in prepronociceptin. Fiber photometry recordings during progressive ratio operant behavior revealed pnVTAPnoc neurons become most active when mice stop seeking natural rewards. Selective pnVTAPnoc neuron ablation, inhibition, and conditional VTA nociceptin receptor (NOPR) deletion increased operant responding, revealing that the pnVTAPnoc nucleus and VTA NOPR signaling are necessary for regulating reward motivation. Additionally, optogenetic and chemogenetic activation of this pnVTAPnoc nucleus caused avoidance and decreased motivation for rewards. These findings provide insight into neuromodulatory circuits that regulate motivated behaviors through identification of a previously unknown neuropeptide-containing pnVTA nucleus that limits motivation for rewards.

Two junior faculty received Rita Allen Foundation Awards in Pain (Links to an external site)

“This funding makes what is easily the riskiest project in the lab a much more secure venture. One of the biggest challenges we face using rodents as models of complicated human conditions is that we cannot ask the animals how they feel. A simple question, but a very difficult one to answer. With this award, we will be working to overcome this barrier by extracting detailed information from videos of the animal’s behavior to determine whether they are in pain, or distress. We will use new types of data analysis from mathematics to essentially ask the mice that simple question, “How do you feel?” By the end of this award, we aim to have made strides in identifying stress and pain in animals without having to disturb their daily routine. This approach will hopefully enable new strategies for understanding neural circuit function and therapeutic development.” – Dr. Jordan McCall, PhD, MPH

““What we found through our studies in mice was that the 7-OH metabolite was responsible for inducing most of the pain relief the mice experienced,” said Majumdar. “Through our research, we discovered that the opioid pharmacology of mitragynine is complicated by the role of 7-OH in mediating its activity. In mouse and human liver preparations, the analgesic effects of mitragynine are actually dependent on 7-OH as a metabolic mechanism.” – Dr. Susruta Majumdar, PhD

“I like to call it the forgotten phase of addiction. I look at the negative effects of relapse and examine what physiological and behavioral changes are happening to drive relapse. I’m also looking at whether less severe withdrawal can prevent relapse. My hope is that if scientists thoroughly understand the neurological effects of withdrawal, they can develop better treatments to help those who are addicted to opioids fully recover from their disease.” – Dr. Ream Al-Hasani, Ph.D.

The United States is in the grip of an epidemic. Opioid drugs are powerful pain-relieving medications, but come with a high risk of addiction. According to the Centers for Disease Control and Prevention, 91 Americans die each day from opioid overdoses, and that figure is rising.
Dr. Majumdar and colleagues are working to combat the epidemic, but perhaps the frontline science is chemistry.
