Work Summary
Our lab is focused on the development of novel peptides to inhibit this inflammatory cascade and improve brain blood flow. These peptides are designed to significantly improve serum half-life and penetrate the blood-brain-barrier. These peptides act to inhibit the inflammatory pathways at both the level of brain blood vessels and the brain itself.
Research Interest
Dr. Hay is internationally known for her work in cardiovascular neurobiology and her current studies on the role of sex and sex hormones in the development of hypertension. She has been continuously funded by the NIH and other sources for the past 26 years. She has extensive experience in central renin angiotensin mechanisms, neurophysiology and reactive oxygen and cytosolic calcium neuroimaging and in advancing knowledge related to central mechanisms of neurohumoral control of the circulation. She is a Professor of Physiology at the University of Arizona College of Medicine and maintains active participation in the American Physiological Society, the Society of Neuroscience, AAAS, and has served on numerous editorial boards of prestigious scientific journals and grant review panels for the National Institutes of Health and the National American Heart Association. The primary focus of Dr. Hay’s laboratory is the understanding of the biophysical and cellular mechanisms underlying neurotransmitter modulation of sympathetic outflow and ultimately arterial blood pressure. The scientific questions being asked are: 1) What central neurotransmitter mechanisms are involved in the normal regulation of cardiovascular function? 2) Does the development of some forms of hypertension involve biophysical or molecular alteration in the neurotransmitter mechanisms regulating cardiovascular control? 3) Can these central signal transduction systems, which control sympathetic outflow and ultimately arterial blood pressure, be altered in order to prevent or attenuate the development of some forms of hypertension? 4) Are there gender related differences in some of these mechanisms?Dr. Hay has extensive national experience in university-wide administration and interdisciplinary research program development. Prior to coming to the University of Arizona in 2008 as Executive Vice President and Provost, Dr. Hay was the Vice President for Research for the University of Iowa, where she worked with state and federal lawmakers, private sector representatives, and local community groups to broaden both private and public support for research universities. Dr. Hay, a Texas native, earned her B.A. in psychology from the University of Colorado, Denver, her M.S. in neurobiology from the University of Texas at San Antonio, and her Ph.D. in cardiovascular pharmacology from the University of Texas Health Sciences Center, San Antonio. She trained as a postdoctoral fellow in the Cardiovascular Center at the University of Iowa College of Medicine and in the Department of Molecular Physiology and Biophysics at Baylor College of Medicine in Houston. She was a tenured faculty member of the University of Missouri-Columbia from 1996-2005. Prior to Missouri, she was a faculty member in the Department of Physiology at the University of Texas Health Science Center- San Antonio.
