Michael Ariel

Pharmacology and physiology
School of Medicine
michael.ariel@health.slu.edu

Michael Ariel, Ph.D., investigates how the brain normally processes sensory inputs. A microelectrode tip is positioned within an animal鈥檚 brain stem that is maintained in vitro while still connected to the eyes and temporal bones. The neuronal activity amplified at that tip is recorded in response to either visual stimulation of the eye, vibration of the ear drum or rotation of the head. One goal of this research is to understand how these sensory inputs control eye movements that lead to the perception of a stable visual world as we move our head or body through our environment. The experiments are performed on neural tissues from pond turtles because of the unique ability of those isolated brain tissues to remain responsive to natural sensory stimuli while lacking blood flow to provide oxygen. Another goal of Ariel鈥檚 research is to determine if these sensory signals can activate the brain stem even during a total lack of oxygen (anoxia). In the normal environment of these turtles in North America, they remain submerged each winter under the frozen surface of freshwater ponds. Ariel鈥檚 experiments hope to reveal which of the sensory systems still function during these winter months in the icy winter waters. Understanding the mechanism of brain survival during anoxia may be important for the treatment of stroke in which oxygenated blood flow is blocked in the human brain.

Andrew Butler

Pharmacology and physiology
School of Medicine
andrew.butler@health.slu.edu

My research interests are in the general area of the integrative physiology of obesity and diabetes. I have published original research articles on the role of melanocortin receptors expressed in the nervous system. The "central nervous melanocortin system" is the canonical neural circuit that integrates signals of energy balance secreted from adipose tissues, the GI tract and pancreas to govern appetite and metabolism. My research has contributed to our knowledge of two melanocortin receptors expressed in the nervous system, one of which (MC4R) is a target for developing drugs against obesity., My current research focuses on a novel "micropeptide" involved in the control of liver metabolism and healthy aging of the nervous system. Proteogenomics has identified over a thousand small open reading frames (sORF) encoding proteins less than 100 amino acids in size. We identified a micropeptide named adropin. Our research focuses on the role of the micropeptide in regulating glucose and fatty acid metabolism in the liver and skeletal muscle. We are also investigating whether this micropeptide is a potential lead for developing treatments for cognitive impairment associated with aging and metabolic disease.

The prevalence of obesity has increased globally and in the US. Obesity and type-2 diabetes also greatly increase the risk of various other diseases such as non-alcoholic fatty liver disease/steatohepatitis (NAFLD/NASH), osteoporosis, atherosclerosis, neurodegeneration, and cancer. Pathways that reduce body fat and insulin resistance are being targeted to treat these diseases. The long-term goal of my lab is to define the mechanisms of these processes for rational drug development. A related goal is to identify and validate novel targets in these diseases. We discovered the inositol pyrophosphate biosynthetic enzyme IP6K1 as a novel target in obesity and type-2 diabetes. Thus, pharmacologic inhibition of IP6K1 should improve human health by boosting metabolism. The ongoing research is to determine cell- and tissue-specific mechanisms by which IP6K1 causes metabolic diseases and to develop IP6K1 inhibitors to treat these diseases. Moreover, we identified several other novel proteins that regulate obesity and insulin resistance, which are currently being characterized in detail.

These techniques include multidimensional protein NMR, isothermal titration calorimetry, surface plasmon resonance, time-resolved FRET, fluorescence polarization, differential scanning fluorimetry and cell-based techniques. Using a metabolomics approach, we identify possible endogenous ligands that bind orphan nuclear receptors, and subsequently map their binding site and characterize the dynamics of the interaction using structural elucidation techniques, such as X-ray crystallography and NMR spectroscopy. We also perform in silico molecular docking of ligand libraries to determine which drug-like molecular scaffolds fit into the pocket, which could corroborate the positive hits identified in the high-throughput biophysical screening.

Our primary objective is to develop innovative strategies for the regeneration and rehabilitation of functional muscle tissue in cases of traumatic injuries, with a specific focus on volumetric muscle loss. To achieve this goal, we are pursuing a regenerative approach that involves the use of multifunctional biomaterials that enhance muscle regeneration and function. These biomaterials are composed of chemically cross-linked extracellular matrix proteins and are processed in various forms such as biosponges, hydrogels, micro-particles or nano-particles, depending on the specific application. These biomaterials not only provide mechanical support but also deliver growth factors, pharmaceuticals, stem cells and exosomes to targeted areas, suppress immune responses and act as a substrate for host cell infiltration and proliferation. Furthermore, we are exploring rehabilitative strategies, including neuromuscular electrical stimulation, to improve muscle mass and strength. Ongoing studies are exploring the combined application of regenerative and rehabilitative strategies to maximize their effectiveness.

Hawiger's Faculty Profile

Conventional dendritic cells (cDC) have crucial roles in priming effector T cells but cDC also have critical tolerogenic functions in the peripheral immune system, extending the maintenance of immune homeostasis and blocking autoimmune responses. However, broad tolerogenic functions of cDC including induction of peripheral regulatory T cells (pTreg cells) could hamper protective immune responses against some pathogens and tumors, whereas an inadvertent activation of autoregressive T cells in the presence of pro-inflammatory stimuli could lead to autoimmunity. Therefore, the maintenance of immune homeostasis by cDC requires specific mechanisms that actively adjust T cell functions to promote tolerance while preserving an overall high plasticity of the immune responses. To clarify the mechanisms by which cDC govern the outcomes of immune activation in the context of autoimmune disorders such as multiple sclerosis (MS) and other immune responses, studies in my laboratory are focused on the roles of specialized subsets of cDC and their specific functions in tolerance and immunity as well as the relevant molecular mechanisms induced by such cDC in T cells. Our work has elucidated the functions of specific immunomodulatory pathways, cell signaling regulators and transcription factors that establish specific outcomes of the interactions between T cells and cDC.

Daniel Warren

Biology

Warren is a comparative animal physiologist whose work includes neurophysiological studies of hypoxia- and anoxia-tolerant animals, especially in turtles. Oxygen deprivation is the primary cause of the neurological injury that is caused by strokes and heart attacks, which costs the United States healthcare system billions of dollars annually. It is, therefore, a national priority to discover ways to prevent, minimize, or reverse brain injury associated with these human diseases. By studying hypoxia- and anoxia-tolerant animals, we seek to identify novel mechanisms of hypoxia tolerance that potentially yield novel targets for future therapeutic interventions for humans. We use a variety of experimental approaches to understand the anoxic responses of the turtle鈥檚 nervous system, including whole tissue and spatial transcriptomics of the brain and functional studies of cultured cortical neurons that include calcium handling and glutamate sensitivity. I collaborate closely with Michael Ariel in Pharmacology and Physiology in studies of special sensory function in hypoxic turtles, especially of the visual and auditory systems.
