The Arrojo e Drigo lab focuses on understanding the mechanisms regulating post-mitotic cell homeostasis and longevity. Many post-mitotic cells can be as old as the organism, which makes them remarkably long-lived. We study long-lived cells in different organs and explore their developmental trajectory, structure-function and aging patterns. Our lab uses a combination of single cell sequencing and high-resolution light, electron and isotope microscopy platforms to overlay cell structure-function with molecular identity, age and metabolism.

Research in the Ayala lab focuses on gut-brain interactions that regulate energy balance. Specifically, we are interested in identifying regions in the central nervous system and molecular mechanisms within those regions that mediate the effects of the gut hormone Glucagon-like peptide-1 (Glp1) and related Glp1 receptor (Glp1r) agonists on feeding behavior. Our lab combines transgenic mouse models, targeted pharmacological interventions and state-of-the-art metabolic phenotyping capabilities to address research questions. We aim to extend the technical expertise in the lab to leverage the existing imaging, circuit mapping, electrophysiology and behavioral phenotyping capabilities at Vanderbilt. Other projects in the lab focus on leveraging biochemical and pharmacological properties of the Glp1r towards the design of more effective therapeutics for obesity and diabetes

Elevated fasting blood glucose (FBG) levels have been associated with an increased risk of type 2 diabetes (T2D) development and cardiovascular-associated mortality (CAM). Genome-wide association studies (GWAS) have identified SNPs in G6PC2 associated with FBG. G6PC2 is an isoform of the glucose-6-phosphatase catalytic subunit expressed in pancreatic islet beta cells. Deletion of G6pc2 in mice results in reduced FBG, consistent with the human GWAS data, and islets from these mice have enhanced glucose-stimulated insulin secretion (GSIS) at sub-maximal glucose concentrations. I am using mouse models to explore the function of G6pc2 in islet beta cells and its potential as a therapeutic target for the prevention of T2D and CAM.

Graduate Student, Gannon Lab, Molecular Physiology & Biophysics
I am originally from Baltimore, MD and I attended The College of New Jersey for my undergraduate degree, where I graduated in 2020 with a B.S. in Biology and a minor in Public Health. I have always had an interest in the science of disease, physiology, and autoimmunity. Type one diabetes is a chronic autoimmune disease resulting in near complete destruction of insulin-producing beta cells in the pancreas leading to reliance on treatment with exogenous insulin to maintain glucose homeostasis. Long-term insulin administration and poor glucose control can lead to numerous complications, and therefore investigating methods to enhance beta cell mass and function is critical in the reversal of disease. In the Gannon lab, I study the effects of modulating prostaglandin E2 (PGE2) signaling through prostanoid receptors EP3 and EP4 on beta cell survival and autoimmune activity in a type one diabetes model, the nonobese diabetic mouse. We hope that through selective antagonism or agonism of these receptors we may be able to enhance beta cell proliferation and survival, as well as dampen the autoimmune attack to allow restoration of beta cell mass and euglycemia. Outside of the lab I love reading, adventuring outdoors, and exploring the sights, sounds and tastes of Nashville!

Graduate Student, Assistant, Associate, Full and Emeritus Professor, Molecular Physiology and Biophysics, 1971-Present
Dr. Corbin, together with Dr. Sharon Francis, devoted his research career to determining the biochemical mechanisms whereby cyclic nucleotides mediate the effects of hormones, neurotransmitters, and other agents on many biological processes. In 1976, he identified a novel protein that bound to cyclic GMP, which was later purified and characterized as being a phosphodiesterase that degrades cyclic GMP. This enzyme, now known as PDE5, is the site of action of drugs used to treat erectile dysfunction. Dr. Corbin was a HHMI investigator for 17 years.
Graduate Student, Hasty laboratory, Molecular Physiology & Biophysics
I am a 5th year graduate student in Alyssa Hasty’s lab. My interests are at the interface of physiology and immunology and I am focused on using bioinformatic approaches to study the relationship between immune cells and metabolic perturbations. My project in the lab is to study adaptive immunity in the context of weight loss and weight regain, which we refer to as weight cycling. To date, little work has been done to describe and define changes in T cell activity within adipose tissue during significant weight changes. In the Hasty lab, I am working to understand the complex interplay between adipocytes, macrophages, and T cells that induces adipose tissue T cell accumulation, activation, tolerance, and hypersensitivity.
Graduate Student, Chen Laboratory, Molecular Physiology and Biophysics
I’m a MPB graduate student in the laboratory of Wenbiao Chen. I am interested in beta cell death in type 2 diabetes and in beta cell proliferation in a glucagon deficient background. I enjoy yoga, tennis, rock climbing and wakesurfing. My research project will investigate the intricate cytokine cross-talk between macrophages and beta cells which leads to beta cell death and dysfunction in type 2 diabetes.

Graduate Student, Jacobson Lab, Molecular Physiology & Biophysics
I am the most recent member to join David Jacobson’s lab! I was born and raised in New Mexico and completed my bachelor’s degree in biochemistry at New Mexico State University. I was accepted into the Interdisciplinary Graduate Program (IGP) at Vanderbilt straight from undergrad in 2020. I am also in the Initiative for Maximizing Student Diversity (IMSD) program.
The Jacobson lab investigates the role of various ion channels in pancreatic islets. Ion channels are important in regulating hormone secretion from islets which is perturbed in diabetic patients. My project will focus on the two-pore-domain potassium channel TALK-2. Interestingly, TALK-2 is not found in rodents which has made it difficult to study. I will use human cell lines to study how TALK-2 influences calcium ER stores, membrane potential, insulin secretion, and more. This work will contribute to our understanding of calcium handling and hormone secretion of beta cells and alpha cells in the context of diabetes and will likely provide new therapeutic targets for the treatment of this disease.

Glaucoma is a major public global health problem accounting for vision loss and blindness in millions of people world-wide. Although glaucoma can be treated by lowering intraocular pressure with medications, laser treatments or surgery, most patients are unaware of decreased vision until advanced stages of the disease. Improved treatment for glaucoma patients requires better understanding of the disease mechanisms and development of early detection strategies. Our broad long term goals are to understand the disease pathophysiology and to identify genetic markers for early detection and better treatment of glaucoma.

Graduate Student, Carrasco Laboratory, Molecular Physiology and Biophysics
I am an international grad student from Spain doing my PhD. at Vanderbilt University. I did my undergrad in biotechnology at University Francisco De Vitoria in Madrid, Spain. My post-baccalaureate training was at Yale University from 2017 to 2019. At Yale I enrolled Dr. Nancy Carrasco’s laboratory and I became interested in understanding the allosteric binding site of NIS. We moved to Vanderbilt University where I started my PhD in the laboratory of Dr. Carrasco. I am trying to understand the mechanism that NIS membrane protein uses to mediate the active transport of Iodide. My project is focused on understanding how the interaction between oxyanions and the allosteric binding site of NIS changes the Iodide transport stoichiometry from electrogenic to electroneutral. I also want to research if there are physiological substrates that interact with NIS allosteric binding site. Finally, I am interested in trying to develop new approaches that allow our lab to elucidate NIS tertiary structure.

Graduate Student, Simerly Laboratory, Molecular Physiology & Biophysics
I grew up in Los Angeles, CA. I attended Duke University as an undergraduate and received a Bachelor of Science in Neuroscience in 2015. After graduation, I worked as a Research Technician at the University of North Carolina at Chapel Hill in the Bowles Center for Alcohol Studies for 2 years where I studied developmental neuroscience in the labs of Dr. Kathleen K. Sulik and Dr. Scott Parnell respectively. I matriculated into the Interdisciplinary Graduate Program here at Vanderbilt University in 2017 and joined Dr. Richard Simerly’s lab as a PhD student in May 2018.
I am interested in developmental neuroscience, specifically how the formation of complex neural circuits early in life impacts physiology into adulthood. Environmental influences that occur early in life, such as nutrition, dictate adaptations of an organism that will affect susceptibility to weight gain and obesity later in life. The hypothalamus plays an essential role in the regulation of energy balance and is impacted by changes in diet during sensitive periods of development. It is also known that high fat diet in adults causes increased activation of microglia in the hypothalamus. Microglia are known to be key regulators in the development of neural circuits, but there is not yet a proposed role for microglia in the development of hypothalamic feeding circuits. My project is focused on defining the role of microglia in the formation of neural circuits that control metabolic state.

Graduate Student, Jacobson Laboratory, Molecular Physiology and Biophysics
I grew up in Kolhapur, India and received my bachelor’s degree in Biotechnology Engineering from Shivaji University, India. Following graduation, I moved to Philadelphia to pursue a master’s degree in Biotechnology at the University of Pennsylvania where my research focused on genetic variation affecting transcriptional regulation of hepatic metabolism by the nuclear receptor PPARα.
Currently, I work in the Jacobson lab studying the mechanistic role of pancreatic ion channels in health and diabetes. My thesis project focuses on developing pharmacology for the pancreatic two-pore domain K+ channel TALK-1. β-cell TALK-1 functions on the plasma membrane and the ER membrane culminate in limiting glucose-stimulated Ca2+ oscillation frequency and pulsatile insulin secretion. KCNK16, the gene that encodes TALK-1, is the most islet-restricted and most abundant β-cell K+ channel transcript. Furthermore, a T2D associated non-synonymous polymorphism (rs1535500) in KCNK16 that causes a gain-of-function (GOF) in TALK-1 may reduce β-cell Ca2+ entry and insulin secretion. Another GOF mutation in TALK-1 (>300X), L114P, causes autosomal dominant maturity onset diabetes of the young (MODY) by reducing glucose-stimulated β-cell Ca2+ influx (GSCI), [Ca2+]ER storage and insulin secretion. Together these data suggest that TALK-1 is an islet-restricted therapeutic target and inhibition of TALK-1 channels could increase Ca2+ oscillation frequency, pulsatile insulin secretion and [Ca2+]ER storage in T2D with minimal off-target effects. My research utilizes a wide range of techniques including high-throughput screening approaches, Ca2+ imaging and electrophysiological recordings to identify and optimize TALK-1 inhibitors and to investigate the therapeutic potential of inhibiting TALK-1 in the treatment of diabetes.
When I’m not in lab, I enjoy painting, music, cooking and traveling.

Graduate Student, Alexander Lab, Molecular Physiology and Biophysics
Hi! I am Bianca and the city I’ve considered home for much of my life has been San Diego, CA. This is where I received a Bachelor’s in Biochemistry/ Cell Biology from UC San Diego and a Master’s in Immunology and Chemical Biology from The Scripps Research Institute. After graduation, I transitioned to the pharmaceutical industry where my project focused on reprogramming the tumor microenvironment to mount a productive anti-tumor inflammatory response. Currently, I am a PhD student in the Alexander Lab where my thesis project focuses on the role of Tregs and inflammatory cells in the context of cardiovascular diseases. One of my favorite things to do in my free time is to surf, though I may need to find new hobbies now that I am in Nashville.

Graduate Student, Penn Laboratory, Molecular Physiology and Biophysics
I was born and raised in Orlando, Florida and finished high school in Anaheim, California. I went to undergrad at Vanderbilt University where I majored in Biological Sciences and minored in Chemistry and Studio Art. In 2018, I graduated and began my PhD in Vanderbilt’s Interdisciplinary Graduate Program. I currently work in John S. Penn’s lab in the department of Molecular Physiology and Biophysics, studying the anti-inflammatory potential of endocannabinoids to slow the disease progression of diabetic retinopathy.
The ultimate goal of my thesis project is to determine if endocannabinoids (eCB) can slow DR disease progression by decreasing cytokine-promoted inflammation. Inflammatory cytokines are elevated in the vitreous and retina of diabetic patients and animals respectively, causing damage to the retinal vasculature known as diabetic retinopathy (DR). Previously, eCB-related epoxides have been shown to inhibit DR-simulated inflammation in vitro and in vivo, however, it is proposed that eCB are more suitable for therapeutic adaptation due to increased stability and known cognate receptors. In particular, eCB may be more potent working through cannabinoid receptor type 2 (CB2), whose activation has been shown to mitigate cellular and tissue inflammation. We hypothesize that the increased inflammation caused by diabetic retinal conditions, as well as the retina’s pro-inflammatory response to this environmental inflammation, can be mitigated by increasing eCB levels and/or CB2 activation. Knowledge gained from focused in vitro studies will facilitate the development of eCB-related therapeutic strategies against the inflammation-driven progression of DR.

The research area pursued by Dr. Pilkis involved hormonal control of hepatic gluconeogenesis and glycolysis via alterations in enzyme activities. He discovered fructose-2,6-bisphosphate, the key allosteric modulator of phosphofructokinase and fructose-1,6-bisphosphatase, the bifunctional enzyme which synthesizes and degrades this regulator, and identified the gene that encodes this protein. This led to his extensive study of the hormonally-mediated regulation of the enzymatic activities of the bifunctional enzyme, including studies of its genetic expression. Dr. Pilkis became Professor and Chairman of Physiology and Biophysics at The State University of New York at Stony Brook in 1986.

Dr. Sutherland’s discovery of adenyl cyclase and cyclic AMP was a seminal contribution and led to the concept of intracellular second messenger signaling. His research linking changes in intracellular enzyme activity to hormones such as glucagon and epinephrine provided a foundation for subsequent decades of work in the areas of hormonal regulation of intracellular metabolism and other processes. These important contributions resulted in election to the National Academy of Sciences and the Nobel Prize for Physiology or Medicine in 1971 for Dr. Sutherland.
Graduate Student, Simerly Laboratory, Molecular Physiology and Biophysics
I am a third year graduate student in Dr. Richard Simerly’s lab. I attended the University of Miami where I graduated with degrees in Neuroscience and Anthropology, and my interest in research developed during my time there. I am interested in developmental neuroscience. A fundamental requirement for all organisms is to coordinate the regulation of fluid and energy balance. While feeding and drinking are coordinated and points of interaction have been identified, the neuroanatomical basis for the integration of feeding and drinking has not been defined, nor has the dependence on the development of those circuitries been examined. The overarching premise of my project is to determine if activation of neural circuits regulating drinking during a critical period of development of hypothalamic feeding circuits impacts the neural architecture of those feeding circuits with lasting consequences for energy balance regulation. The results of my studies will not only facilitate an improved understanding of how the brain integrates drinking and feeding by defining nodes of convergence, but will provide new insight into unappreciated developmental events impacting metabolic phenotypes throughout life.

The prevalence type 2 diabetes (T2D) continues to increase worldwide. Multiple SNPs associated with altered risk of T2D have been identified through genome wide association studies including rs13266634 in the SLC30A8 locus, which encodes zinc transporter 8 (ZnT8). In addition, rare mutations resulting in SLC30A8 haploinsufficiency are protective against T2D. Using several mouse models, we are investigating the role that ZnT8 plays in beta cell function and the potential of ZnT8 as a therapeutic target for T2D.

I grew up in Queens, NY and graduated from Amherst College with a B.A. in neuroscience. Outside of lab, I enjoy learning digital art, checking out new coffee shops, cooking and playing games with friends. My thesis project involves examining the role of matricellular protein, CCN2, which has been demonstrated to induce insulin-producing β-cell proliferation during conditions both in vivo and ex vivo. I will identify the role of CCN2 in β-cell proliferation during high-fat diet and investigate the mechanism by which it has its action using a transgenic embryonic mouse model of β-cell specific c-Met inactivation. Through my studies, I will uncover more information about how CCN2 induces β-cell proliferation, uncovering a role for CCN2 as a potential therapeutic for Type 2 Diabetes (T2D).
Graduate Student, Neuert Laboratory, Molecular Physiology & Biophysics
In the Neuert Lab, I study long noncoding RNAs (lncRNAs), a class of non-protein coding transcripts that represents an emerging, previously unrecognized layer of gene regulation.

Hi there! My name is Katie Volk and I am a PhD candidate in the lab of Dr. Alyssa Hasty. I am originally from just outside Los Angeles, CA and arrived at Vanderbilt after completing my undergraduate degree at Washington and Lee University in Virginia. In the Hasty lab, I study the role that microglial cells play in either propagating or protecting against Alzheimer’s Disease and neurodegenerative pathology. Particularly, Alzheimer’s Disease is often characterized by neuroinflammation and excessive brain iron load; and I am interested in understanding the dual roles that microglia play in dictating changes in inflammation and iron-handling in the brain. Ultimately, my hope is that this work contributes to our growing understanding of Alzheimer’s pathology and eventually aids in the development of successful therapeutics in the future.
Graduate Student, Powers laboratory, Molecular Physiology & Biophysics
I am an MD/PhD student who joined the lab of Al Powers and Marcela Brissova in 2016. I am originally from Kansas City and did my undergraduate work at Washington University in St. Louis. In undergrad, I worked on research projects that used novel chemical techniques to elucidate protein structure and function. In the Powers and Brissova lab, I am interested in mechanisms of human islet function and dysfunction and use unique models including in vivo transplantation of human islets and dispersion and reaggregation of islet cells to form pseudoislets. I am also characterizing the functional, morphologic, and transcriptional profiles of islets, sorted α and β cells, and pancreatic tissue from individuals with type 2 diabetes and using viral manipulation in the pseudoislet system to understand mechanisms of islet dysfunction in type 2 diabetes. I plan to pursue a career as a physician-scientist in pediatric endocrinology upon his return to medical school.
