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. |

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. |

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. |

During development transcriptional and posttranscriptional networks are coordinately regulated to drive organ maturation, tissue formation, and cell fate. Interestingly, more than 90% of the human genes undergo alternative splicing, a posttranscriptional mechanism that explains how one gene can give rise to multiple protein isoforms. Heart and skeletal muscle are two of the tissues where the most tissue specific splicing takes place raising the question of how developmental stage- and tissue-specific splicing influence protein function and how this regulation occurs. In my lab we are interested on two exciting aspects of this broad question: i) how alternative splicing of trafficking and membrane remodeling genes contributes to muscle development, structure, and function, ii) the coupling between epigenetics and alternative splicing in postnatal heart development. |

PHD PROGRAM RESEARCH INTEREST |
The Shiau Lab is integrating in vivo imaging, genetics, genome editing, functional genomics, bioinformatics, and cell biology to uncover and understand innate immune functions in development and disease. From single genes to individual cells to whole organism, we are using the vertebrate zebrafish model to reveal and connect mechanisms at multiple scales. Of particular interest are 1) the genetic regulation of macrophage activation to prevent inappropriate inflammatory and autoimmune conditions, and 2) how different tissue-resident macrophages impact vertebrate development and homeostasis particularly in the brain and gut, such as the role of microglia in brain development and animal behavior. |

It is estimated that less than 2% of the human genome codes for a functional protein. Scattered throughout the rest of the genome are regulatory regions that can exert control over genes hundreds of thousands of base pairs away through the formation of DNA loops. These loops regulate virtually all biological functions but play an especially critical role in cellular differentiation and human development. While this phenomenon has been known for thirty years or more, only a handful of such loops have been functionally characterized. In our lab we use a combination of cutting edge genomics (in situ Hi-C, ATAC-seq, ChIP-seq), proteomics, genome editing (CRISPR/Cas), and bioinformatics to characterize and functionally interrogate dynamic DNA looping during monocyte differentiation. We study this process both in both healthy cells and in the context of rheumatoid arthritis and our findings have broad implications for both cell biology as well as the diagnosis and treatment of human disease. |

Our laboratory studies an amazing regulatory factor known as NF-kappaB. This transcription factor controls key developmental and immunological functions and its dysregulation lies at the heart of virtually all major human diseases. |
