Bio
Dr. Regal was named the Co-Interim Regional Campus Dean of the University of Minnesota Medical School, Duluth Campus. She became active in this role on April 19, 2021 through Summer 2022.
Research Summary
The overall goals of my research program involve understanding basic immune mechanisms of cardiopulmonary disease. I have a long-standing interest in the complement system as a mediator of adverse events in disease states such as anaphylaxis, asthma and most currently pregnancy-induced hypertension. These interests have also involved defining mechanisms of pulmonary immunotoxicity of small molecule workplace allergens such as trimellitic anhydride. My research approach involves experimentation at the molecular, biochemical and physiological levels using animal models of disease. Current research projects include:
Pregnancy-induced Hypertension Preeclampsia and related hypertensive disorders of pregnancy affect ~10% of all pregnancies in the United States, significantly impacting the health of both mother and child. The initiating event of preeclampsia involves impaired blood flow to the placenta and the end result for the mother is high blood pressure and protein in the urine, along with growth restriction in the fetus. During pregnancy, the immune system including the plasma complement system, is tightly regulated to allow fetal survival. In women with preeclampsia the complement system is excessively activated, and our long-term goal is to determine the therapeutic utility of manipulating the complement system to prevent preeclampsia or minimize consequences for the mother and child. We hypothesized that complement system activation and white blood cell recruitment lead to hypertension in the mother and growth restriction in the fetus. Thus, we are manipulating the complement system and white blood cell function in a model of placental ischemia induced high blood pressure to determine the critical mechanisms responsible for the pregnancy complications. Our most recent studies are defining the role of natural antibody and the B lymphocyte in initiating complement activation in vivo, and assessing the importance of endogenous complement regulators in limiting the activation.
Dr. Regal's lab is currently funded through the National Heart Lung and Blood Institute of NIH and the American heart Association.

Research Summary
The brain depends upon a supply of blood-borne nutrients to maintain its physiological function. A hallmark characteristic of the brain vasculature is an endothelium with tight occluding junctions at positions of cell-cell contact. This absence of spaces between cells prevents bulk diffusion of plasma components into the surrounding tissue. The net result of this "blood-brain barrier" is that influx and efflux of metabolic substrates and nutrients (including glucose, amino acids, and nucleosides) across the brain vasculature must occur via transport systems located in the luminal and abluminal plasma membranes of the endothelial cell. For example, glucose is the primary substrate for brain metabolism and is transported into cells via specific membrane carriers. Under normal glycemic conditions, GLUT1 and GLUT3 are the known members of the glucose transporter family responsible for carrying glucose from the blood and into the cells of the brain. This includes transport across both the luminal and abluminal sides of the endothelial cell and the plasma membranes of the neuronal and glial cells. Although recent studies have greatly expanded our knowledge about glucose transporters in several tissues, much less is currently known about these integral membrane proteins in the brain or how they are regulated in response to pathophysiological conditions. The long-term goals of my research are to characterize the molecular process by which nutrients are transported through the cells comprising the blood-brain barrier (endothelial cells) and the blood-CSF barrier (epithelial cells of the choroid plexus). These goals include an understanding of the molecular identity of the transporters, the membrane sites where transporters are located, the kinetic characteristics of substrate and inhibitor specificity, and, in the future, the mechanisms regulating trans porter activity and expression. Research describing the molecular events of blood-brain transport may be valuable in understanding neurological dysfunctions associated with stroke, diabetes, neurodegenerative diseases and metabolic encephalopathies. Indeed, it could lead to treatment s for minimizing these dysfunctions or for designing therapeutic strategies.

Research Summary
The focus of our molecular parasitology laboratory is trypanosomes. Species of these vector-borne protozoan parasites cause World Health Organization-designated Neglected Tropical Diseases that are endemic to poor, rural populations and for which new drug targets are urgently needed. The laboratory studies aspects of their metabolism and mitochondrial gene expression, looking not only for vulnerabilities that may serve as new drug targets but also at processes that can inform our fundamental understanding of eukaryotic evolution.
