Lee Limbird (born November 27, 1948, in Philadelphia, Pennsylvania) is a pharmacologist, Dean of the School of Natural Science, Mathematics and Business & Professor in the Department of Life and Physical Sciences at Fisk University, Nashville, Tennessee. [1] [2]
Limbird has been recognized for "outstanding scientific contributions in research and mentoring in pharmacology", in particular her "pioneering research on alpha-2 adrenergic receptors and how they relate to the regulation of blood pressure, sedation, pain suppression and opioid drug action". Among other awards, she received the Julius Axelrod Award from the American Society for Pharmacology and Experimental Therapeutics (ASPET) in 2013. [2]
Lee Eberhardt was born on November 27, 1948, in Philadelphia, Pennsylvania. [3]
Eberhardt attended the College of Wooster in Wooster, Ohio, working in her fourth year with analytical chemist Theodore Roosevelt Williams. Her independent study project, “Role of CPK Isoenzymes in the Diagnosis of Myocardial Infarction,” was co-mentored by Galen Wagner at Duke University. [4] Eberhardt received her B.A. in chemistry in 1970 from the College of Wooster. [5] [6] She subsequently married Tom Limbird, who was a student and resident in orthopedic surgery at Duke. [4]
In 1970, Lee Limbird joined the PhD program in biochemistry at the University of North Carolina, Chapel Hill. She left after two semesters but was encouraged to continue working on creatine phosphokinase (CPK) isoenzyme detection as a research assistant with Charles Roe at Duke University. Limbird's research, showing the importance of the MB isozyme of CPK in myocardial tissue for diagnosis of cardiac infarction, was accepted as the basis for her PhD degree, awarded in 1973 by UNC Chapel Hill. She then became a postdoctoral student, working with Robert J. Lefkowitz on the molecular basis of cardiac disease. [4] One of his first students, she is credited with helping to establish the research direction of the Lefkowitz laboratory. [7]
In 1979, Limbird joined Vanderbilt University as an Assistant Professor of Pharmacology. She led her own lab for several years, focusing on the actions of epinephrine and norepinephrine in alpha2-adrenergic receptor pathways. [4] [5]
Limbird served as Chair of the Department of Pharmacology at the Vanderbilt School of Medicine from 1991-1998, and was the first Associate Vice Chancellor for Research of the Vanderbilt University Medical Center from 1998-2003. [4] [5] With Hal Moses, Limbird was instrumental in determining the 1997 strategic plan for the program. [8]
After 25 years at Vanderbilt, Limbird chose to join minority-serving institutions, in hopes of using her scientific administrative, and personal experience to help counter the impact of systemic racism. [4] In 2005, she became Vice President for Research and Chair of the Department of Biomedical Sciences at Meharry Medical College. In 2008, Limbird became Dean of the School of Natural Sciences, Mathematics and Business Administration at Fisk University in Nashville, Tennessee. [5]
Much of Limbird's research has explored the activity of G-protein coupled receptors. She has demonstrated how alpha-2 adrenergic receptors are involved in regulation of blood pressure, suppression of pain, sedation and the action of opioid drugs. She has developed techniques for selectively manipulating such receptors. [2]
Limbird is the author of Cell Surface Receptors: A Short Course in Theory and Methods (1985, 1996, 2004); co-editor with Joel Hardman of the 9th (1995) and 10th (2001) editions of Goodman and Gilman’s Pharmacological Basis of Therapeutics ; [5] editor of Alpha2-Adrenergic Receptors (1988) and co-editor with Stephen Lanier of α2-Adrenergic Receptors. Structure, Function and Therapeutic Implications (1996). [3] Limbird has served on the editorial boards of the Journal of Biological Chemistry , the American Journal of Physiology , and Molecular Pharmacology . [5] [3]
Alfred Goodman Gilman was an American pharmacologist and biochemist. He and Martin Rodbell shared the 1994 Nobel Prize in Physiology or Medicine "for their discovery of G-proteins and the role of these proteins in signal transduction in cells."
Hexamethonium is a non-depolarising ganglionic blocker, a neuronal nicotinic (nAChR) receptor antagonist that acts in autonomic ganglia by binding mostly in or on the nAChR receptor, and not the acetylcholine binding site itself. It does not have any effect on the muscarinic acetylcholine receptors (mAChR) located on target organs of the parasympathetic nervous system, nor on the nicotinic receptors at the skeletal neuromuscular junction, but acts as antagonist at the nicotinic acetylcholine receptors located in sympathetic and parasympathetic ganglia (nAChR).

Robert Joseph Lefkowitz is an American physician and biochemist. He is best known for his groundbreaking discoveries that reveal the inner workings of an important family G protein-coupled receptors, for which he was awarded the 2012 Nobel Prize for Chemistry with Brian Kobilka. He is currently an Investigator with the Howard Hughes Medical Institute as well as a James B. Duke Professor of Medicine and Professor of Biochemistry and Chemistry at Duke University.
Alpha-adrenergic agonists are a class of sympathomimetic agents that selectively stimulates alpha adrenergic receptors. The alpha-adrenergic receptor has two subclasses α1 and α2. Alpha 2 receptors are associated with sympatholytic properties. Alpha-adrenergic agonists have the opposite function of alpha blockers. Alpha adrenoreceptor ligands mimic the action of epinephrine and norepinephrine signaling in the heart, smooth muscle and central nervous system, with norepinephrine being the highest affinity. The activation of α1 stimulates the membrane bound enzyme phospholipase C, and activation of α2 inhibits the enzyme adenylate cyclase. Inactivation of adenylate cyclase in turn leads to the inactivation of the secondary messenger cyclic adenosine monophosphate and induces smooth muscle and blood vessel constriction.
The alpha-2B adrenergic receptor, is a G-protein coupled receptor. It is a subtype of the adrenergic receptor family. The human gene encoding this receptor has the symbol ADRA2B. ADRA2B orthologs have been identified in several mammals.
Brian Kent Kobilka is an American physiologist and a recipient of the 2012 Nobel Prize in Chemistry with Robert Lefkowitz for discoveries that reveal the workings of G protein-coupled receptors. He is currently a professor in the department of Molecular and Cellular Physiology at Stanford University School of Medicine. He is also a co-founder of ConfometRx, a biotechnology company focusing on G protein-coupled receptors. He was named a member of the National Academy of Sciences in 2011.

Nancy Rutledge Zahniser was an American pharmacologist, best known for her work involving the mechanism of dopaminergic pathways and chemical modifications of them. Although born in Ann Arbor, Michigan, Zahniser grew up in Chillicothe, Ohio and subsequently enrolled at the College of Wooster, where she obtained a degree in chemistry. After completing her degree, Zahniser spent some time in India where she met her first husband Mark Zahniser; she later returned to the United States to attend the University of Pittsburgh School of Pharmacy, where she earned her PhD in pharmacology in 1977. Zahniser went on to complete her post-doctoral training at the University of Colorado Health Sciences Center's Department of Pharmacology and then became a part of the faculty there. In 2007, she became associate dean for research education. She played a role in advancing the careers of many post-doctoral students in her lab. In addition to her work as a professor, Zahniser was also a member of several boards, committees, review panels, and professional societies related to pharmacology, neuroscience, and addiction. She led several national research meetings from 1995-2002.

Joan Heller Brown is an American pharmacologist. She is Distinguished Professor and Chair of the Department of Pharmacology at UC San Diego School of Medicine. She is known for fundamental contributions to the understanding of G-protein coupled receptors (GPCRs) — molecules that span cell membranes, where they transmit messages between cells and their environments — and how GPCRs regulate cell growth and survival, in healthy and various disease states. Many therapeutic drugs work by influencing GPCRs, thus Heller Brown's discoveries have been crucial to their development.
