Hursting, Stephen D WEBSITE PUBLICATIONS |
PHD PROGRAM RESEARCH INTEREST |
Dr. Hursting’s lab focuses on the molecular and metabolic mechanisms underlying nutrition and cancer associations, particularly the impact of obesity and energy balance modulation (eg, calorie restriction, exercise) on cancer development or responses to chemotherapy. Primarily using genetically engineered mouse models of pancreatic, colon and breast cancer, Dr. Hursting has identified the IGF-1/Akt/mTOR and NF-kB signaling pathways as key targets for breaking the obesity- cancer link. He has also established in several preclinical models of pancreatic and breast cancer that obesity impacts the response to various forms of chemotherapy. In addition, the Hursting lab is involved in several translational research collaborations linking mouse model studies with clinical trials, and his group has expertise in measuring metabolic hormones, growth factors, inflammatory cytokines and chemokines in serum and tissue from rodents and humans. |

Research in our lab is focused on understanding how cocaine abuse affects glial cell physiology, in particular neuron-astrocyte communication. We utilize the rat cocaine self-administration/reinstatement model, which allows us to test hypotheses regarding not only how chronic cocaine use affects properties of astrocytes and the tripartite synapse, but also how compounds affecting glial cells may influence synaptic processing within the brain’s reward neurocircuitry and behavioral measures of drug seeking. |

PHD PROGRAM RESEARCH INTEREST |
Our lab has two areas of interest: the molecular basis of liver diseases and the biochemical mechanisms of disorders linked to intermediate filament gene mutations. We use biochemical, cell-based and in vivo approaches to identify potential disease targets and to understand their function and regulation. The major goal of our work is to promote the discovery of pharmacological agents that can slow or halt the progression of these diseases. |
McElligott, Zoe WEBSITE PUBLICATIONS |
PHD PROGRAM RESEARCH INTEREST |
Research in the McElligott lab focuses on the circuits and plasticity that underlie the development and manifestation of psychiatric illness, specifically disorders on the affective spectrum including alcohol use disorders, drug abuse and anxiety disorders. The lab has expertise in studying neurotransmission from the level of signaling in individual cells through behavior utilizing a variety of techniques including: whole-cell electrophysiology, in vivo and ex vivo fast-scan cyclic voltammetry (FSCV), circuit manipulations (optogenetics, chemogenetics, caspase ablation), and behavioral assays. There are several ongoing projects in the lab. One area we are focused on explores the role of neurons in the central nucleus of the amygdala (CeA) that express the neuropeptide neurotensin and the role these neurons play in alcohol related phenotypes. Additionally we are interested in exploring how norepinephrine modulates neurotransmission within the brain and how the norepinephrine system itself is modulated in models of substance abuse and post-traumatic stress. Beyond these studies, we are actively engaged in several other collaborative projects with other labs at UNC, as well as around the world. |
Cohen, Jessica WEBSITE PUBLICATIONS |
PHD PROGRAM RESEARCH INTEREST |
The Cohen Lab investigates how functional brain networks in humans interact and reconfigure when confronted with changing cognitive demands, when experiencing transformations across development, and when facing disruptions in healthy functioning due to disease. We are also interested in how this neural flexibility contributes to flexibility in control and the ability to learn, as well as the consequences of dysfunction in this flexibility. We use behavioral, neuroimaging, and clinical approaches taken from neuroscience, psychology, and mathematics to address our research questions. |

PHD PROGRAM RESEARCH INTEREST |
How do networks of cells synchronize behaviors across differing spatial and temporal scales? This fundamental aspect of cellular dynamics is broadly relevant to understanding many biological systems in which the coherence of electrical or chemical signals is required for multicellular patterning or organ function. Our group’s primary research interests are related to understanding the cellular and microenvironmental conditions that are required to support the biorhythmic behavior of the system of cells that natively control heart rate, cardiac pacemaker cells. We utilize a variety of techniques including computational modeling, next generation sequencing, in vivo genetic manipulation, super-resolution imaging, and direct physiological recording to investigate the developmental processes that assemble the hearts pacemaking complex. The ultimate goals of these studies is to determine how the pacemaker cell lineage is patterned in the embryo, build strategies towards fabricating this cell type for therapeutic purposes, and identify vulnerabilities that may lead to pacemaker cell pathologies in humans. |
