Our primary research interest is to identify the mechanisms that regulate neural circuit organization and function at distinct stages of adult neurogenesis, and to understand how circuit-level information-processing properties are remodeled by the integration of new neurons into existing circuits and how disregulation of this process may contribute to various neurological and mental disorders. Our long-range goals are to translate general principles governing neural network function into directions relevant for understanding neurological and psychiatric diseases. We are addressing these questions using a combination of cutting-edge technologies and approaches, including optogenetics, high-resolution microscopy, in vitro and in vivo electrophysiology, genetic lineage tracing and molecular biology.

The overall focus of research in my laboratory is to improve the diagnosis and treatment of airway diseases, especially those that result from impaired mucociliary clearance. In particular, our efforts focus on the diseases cystic fibrosis and primary ciliary dyskinesia, two diseases caused by genetic mutations that impair mucociliary clearance and lead to recurrent lung infections. The work in our laboratory ranges from basic studies of ciliated cells and the proteins that make up the complex structure of the motile cilia, to translational studies of new drugs and gene therapy vectors. We use a number of model systems, including traditional and inducible animal models, in vitro culture of differentiated mouse and human airway epithelial cells, and direct studies of human tissues. We also use a wide range of experimental techniques, from studies of RNA expression and proteomics to measuring ciliary activity in cultured cells and whole animals.

The Loeser lab uses a combination of in vitro studies in articular chondrocytes and in vivo studies in mice to examine molecular mechanisms of joint tissue destruction in aging and osteoarthritis. A major focus of this work is examining how reactive oxygen species regulate cell signaling through oxidation of Cys residues in specific kinases and phosphatases. Pathways of interest include integrin mediated signaling that stimulates matrix metalloproteinase (MMP) expression and IGF-I signaling that stimulates matrix production. Oxidative stress disrupts the balance in the activity of these pathways to favor matrix destruction over repair contributing to the development of osteoarthritis.

The UNC Food Allergy Institute (UNCFAI) was established in 2012 to address the growing needs of children and adults with food allergy. Program investigators study the biologic basis of food allergy in the laboratory and in clinical research studies seeking to better understand the role of allergen-specific IgE and the mechanism of allergen immunotherapy. The Institute provides comprehensive, family-centered patient care for food allergy, food-related anaphylaxis, and other related disorders like atopic dermatitis and eosinophilic esophagitis.

Our laboratory is broadly interested in understanding the molecular mechanisms of transcriptional regulation by cell signaling pathways and the role of pathway cross-talk in cancer biology. In particular, the cAMP signaling cascade directs adaptive cellular responses to a variety of stress stimuli via a combination of acute affects arising from GS-protein coupled receptor (GPCR)-mediated activation of PKA and long-term affects resulting from transcriptional reprogramming directed by CREB and the CREB Regulated Transcription Coactivators (CTRCs). We are applying an interdisciplinary approach to study the consequences of aberrant activation of the cAMP/CREB/CRTC signal circuit on these adaptive responses and how cooperative signaling with other pathways promotes oncogenic processes in oral, head, and neck cancers.

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.

The goal of my research is to define molecular mechanisms of immune cell co-option by cancer cells, with the hope of identifying novel targets for immune cell reprogramming. Central to our approach is analysis immune cell subtypes in KRas-driven models of pancreatic cancer. We use cell and animals models to study signals important for pro-tumorigenic activity of immune cells, as well as define role of physiologically relevant oncogenic mutations in driving these signals and enabling immune escape.

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.

Dr. McCullough’s lab takes a translational research approach that incorporates primary cell and organotypic in vitromodels with clinical research (controlled human exposures) to study the role of cellular and molecular mechanisms in mediating the local and systemic effects of exposure to inhaled chemicals.  His laboratory utilizes primary cell/organotypic in vitro models, live cell imaging of fluorescent biosensors, and both traditional and advanced molecular biology/biochemistry methods to characterize the relationship between redox dysfunction/oxidative stress, inflammation, cell signaling pathway activation, epigenetic changes, gene expression, and cell-specific functional outcomes.  In addition to identifying the mechanisms involved in the effects of toxic exposures, Dr. McCullough’s research also aims to identify biomarkers of toxic exposure effects, predicting susceptible populations, and identifying factors that can be used to mitigate adverse exposure outcomes.

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.
