In our latest pain research webinar, Dr. Laura Stone, anesthesiology professor at the University of Minnesota, presents findings on low back pain that involve both human and animal models. She discusses dysregulation of nerve growth factor and immune mediators in human cerebrospinal fluid and intervertebral discs obtained from patients vs. controls. She also explores proof-of-concept studies targeting these mechanisms in a pre-clinical model of low back pain, and presents human and animal study data implicating epigenetic mechanisms in chronic pain.
Pain is the chief morbidity that severely decreases the quality of life of patients who suffer from sickle cell disease (SCD). Many also suffer from chronic pain that may result from chronic inflammation and dysregulated neuronal firing and connectivity within the peripheral and central nervous system. In this webinar, Dr. Cheryl Stucky, Director of the Neuroscience Doctoral Program at the Medical College of Wisconsin, discusses her lab’s work interrogating peripheral mechanisms underlying sickle cell pain by using rodent models of SCD in combination with electrophysiological, cellular and behavioral assays. She also discusses her work with colleagues to investigate phenotypes and mechanisms of pain in patients with sickle cell disease.
There is an urgent need for new therapeutics to address chronic pain, which affects approximately 20% of U.S. adults. This 60-minute webinar, presented by Dr. Ted Price, neuroscience professor at the University of Texas at Dallas, focused on utilizing human dorsal root ganglia (DRG) samples from patients and organ donors to gain new insight into the molecular mechanisms that may underlie chronic pain. Dr. Price also discusses integrating sensory neuronal transcriptomics with other datasets more widely available from patients to better understand how the nervous system interacts with diseased tissues to promote chronic pain. This unique approach offers opportunities to thoroughly vet pain targets without relying heavily on pre-clinical models.
Respiratory complications are the primary cause of hospitalization in COVID-19 patients, with complex interactions between the virus, lung epithelial cells and immune cells leading to severe acute respiratory syndrome. As scientists race to develop therapeutics to fight the virus, it is important to have research tools available that provide highly translatable data. The precision cut lung slice (PCLS) discussed in this hour-long webinar, presented by Harvard professors Dr. Rama Krishnan and Dr. Joseph Brain, are an advanced paradigm for translational lung research and are an effective preparation for advancing lung-related physiology. Additional practical advantages of PCLS includes its ease of preparation, ease of storage (via cryopreservation), suitability for high-resolution microscopy imaging and inclusion of many species, particularly human.
Dr. Najah Abi-Gerges, Vice President of Research & Development at AnaBios, presents the first research study on the impact of late sodium current (INa,L) modulation on the excitation-contraction coupling in adult human primary cardiomyocytes in this new webinar. This data demonstrates that these human cardiomyocytes (1) express functional INa,L, (2) can differentiate INa,L facilitators from inhibitors and (3) provide valuable assessment of novel INa,L inhibitors to prevent the occurrence of drug-induced pro-arrhythmia and aid in the development of dysrhythmia medications. In addition, this 60-minute webinar presents information about AnaBios’ unique human tissue platform and electrophysiological and imaging capabilities. We are the only CRO that procures ethically consented human organs from a vast donor network in the United States. We also perform physiological assays using the cells and tissues from these organs. Learn about the different types of human tissue and cell-based assays and how translational assays are impacting preclinical drug discovery.
Dr. Michael Hildebrand, associate professor of neuroscience at Carleton University, highlights his recent work aimed at bridging the translational divide between target identification in rodent models of chronic pain and direct clinical testing of candidate compounds in humans. His research team has developed a novel human spinal cord tissue model of pathological pain that parallels rodent in vivo and ex vivo pain models. Using these complementary approaches, Dr. Hildebrand and his team are identifying molecular determinants of spinal cord hyperexcitability that are conserved across species, and thus may inform the rational development of more effective therapeutics for chronic pain.
