Artem Barski, PhD, is interested in epigenetic and transcriptional regulation of gene expression. During his post-doctoral training in Keji Zhao lab at NIH, Dr. Barski took part in the development of ChIP-Seq, a revolutionary method that combines ChIP with the next-generation sequencing. ChIP-Seq allows genome-wide mapping of chromatin modifications and transcription factor binding sites with resolution and sensitivity far exceeding older methods. Together with his NIH colleagues Dr. Barski used this approach to map more than 40 chromatin modifications in human T cells, which fundamentally improved the understanding of epigenetic regulation of transcription. Dr. Barski has since been using ChIP-Seq and other sequencing-based genome-wide methods to understand the role of chromatin modifications in gene regulation. His most recent work includes investigation of chromatin regulation of genes transcribed by RNA Polymerase III and the discovery of gene poising in T cells.
Since his arrival to Cincinnati Children’s Hospital Medical Center in 2011, Dr. Barski is utilizing ChIP-Seq, RNA-Seq and other cutting-edge approaches to understand epigenetic basis of T cell activation, memory and tolerance.

Jay L. Degen, PhD, is studying the regulation and biological roles of urokinase-type plasminogen activator (uPA) and tissue-type plasminogen activator (tPA), the two mammalian enzymes that convert plasminogen to the active serine protease, plasmin.
The PA/plasmin system of proteases is of particular interest because of its apparent dual function in the lysis of vascular fibrin clots (fibrinolysis) and the degradation of extracellular matrix in tissue remodeling and cell migration events.
Over the last few years, Dr. Degen's lab has generated and characterized gene-targeted mouse lines with deficits in the factors that are the foundation of the coagulation and fibrinolytic cascades, including fibrinogen-, plasminogen-, plasminogen activator-, and plasminogen activator receptor-deficient mouse lines.
These unique experimental animals are being intensively analyzed with regard to a wide range of phenotypic properties, including hemostasis, wound healing, angiogenesis and tumor biology.

Marie-Dominique Filippi, PhD
I am particularly interested in dissecting the molecular mechanism of hematopoietic cell migration, including neutrophils and hematopoietic stem cells in physiological settings. Migration is a critical function of hematopoietic cell in which actin cytoskeleton reorganization plays a central role. Because hematopoietic cells are utilized for the therapy of multiple blood diseases and neutrophils are responsible for maintaining an immunocompetence status, understanding the molecular mechanism of normal hematopoietic cell functions is of potential therapeutic importance. The small RHO GTPase family, members of the Ras superfamily, including Rac, RHO and CDC42, play key roles in regulating many of these functions. During my post-doc in the laboratory of Dr David Williams, we have demonstrated that two highly related proteins, Rac1 and Rac2, of the small Rho GTPase family, have distinct functions in the control of hematopoietic cell functions. In particular in neutrophils, we have shown that both Rac1 and Rac2 regulate cell migration but with distinct mechanism (Gu and Filippi et al, Science 2003) both in vitro and in vivo. In addition to this work, we have dissected the sequence/determinant specificity of Rac2 versus Rac1 functions in neutrophils and demonstrated that Rac2 controls its functions, at least in part, by distinct subcellular distributions of these GTPases (Tao et al, Blood 2002, Filippi et al, Nat Immunol 2004), highlighting one important mechanism controlling cellular functions. My laboratory, in collaboration Dr. Yi Zheng, is now focused on determining the role of CDC42 and RhoA in neutrophil migration and in determining specifically the role of RhoA in hematopoietic stem cell migration and proliferation using gene targeted knock out mice for CDC42 and RhoA and their respective regulator CDC42GAP and 190RhoGAP. These studies will use in vitro and in vivo assays of cell migration as well as immunofluorescence microscopy to study cytoskeleton rearrangement associated with cell migration. The long term goal of these studies is to identify new molecular targets of potential therapeutic importance.

Matthew J. Flick, PhD
is working to understand how hemostatic factors in the blood that are responsible for clotting also drive inflammation in the context of infection and diseases such as arthritis and fatty liver disease.
Research Interests and Focus:
1. Activation of the coagulation system, including the central coagulation protease thrombin, is a prominent feature of both human rheumatoid arthritis and experimental inflammatory arthritis. The long-term goal of Dr. Flick's research program is to determine how thrombin drives inflammatory joint disease. The proposed work will fill significant gaps in the understanding of the interplay between the thrombin- fibrinogen axis and arthritic disease, and may provide the proof-of-principle for the use of novel "customized" thrombin mutants with selected substrate specificity to treat arthritis.
2. The pervasive gram-positive bacteria Staphylococcus aureus is a common pathogen that is the causative agent for a wide spectrum of diseases including skin infections, pneumonia, bacteremia, toxic-shock syndrome and sepsis. Notably, this pathogen has evolved and maintained a number of proteins that directly engage the host hemostatic system, including factors that directly interact with the host coagulation factor fibrinogen. The long-term goal of his research program is to understand how bacterial derived proteins interact with host factors to promote bacterial virulence in the context of blood-born infections. This work will provide novel insight into the molecular pathways by which S. aureus invades and disseminates within host tissues and may shed light into novel strategies for eliminating this potentially devastating infectious agent.
3. Obesity is a worldwide epidemic linked to numerous disease sequelae, including non-alcoholic fatty liver disease (NAFLD). This spectrum disorder can progress from the simple accumulation of triglycerides within hepatocytes (i.e., steatosis), to inflammatory steatohepatitis, to organ failure secondary to irreversible liver fibrosis and cirrhosis. Dysregulation of the coagulation system has been documented in both patients with fatty liver disease and animal models of NAFLD, but any contribution to disease progression has remained largely undefined. Using a murine model of high fat diet (HFD)-induced NAFLD, they are testing the hypothesis that thrombin activity and fibrin deposition drive local inflammatory events promoting the progression of steatosis and steatohepatitis. Comparative studies of wild-type mice with genetically imposed deficiencies or functional alterations in prothrombin, fibrinogen and other associated coagulation factor components suggests that the thrombin-fibrinogen axis influences NAFLD pathogenesis by controlling local inflammatory processes that drive steatosis and by an unanticipated and unknown mechanism tying fibrin(ogen) to HFD-induced weight gain/obesity. Their research has far-reaching implications not only for the treatment and prevention of fatty liver disease, but also for all the downstream sequelae of obesity and even the development of diet-mediated weight gain itself.

The cloning and characterization of oncoproteins and tumor suppressors over the last 25 years has not only resulted in a greater understanding of the molecular mechanisms of transformation, but it has also provided a large set of therapeutic targets. Our lab is interested in the progression of a cell with a single genetic lesion to an invasive cancer with multiple genetic alterations. We focus on the Growth factor independence-1 (Gfi1) transcription factor, which is poorly oncogenic alone, but which potently collaborates with well known oncoproteins such as c-MYC. Gfi1 is the most frequently targeted gene in Moloney murine leukemia virus-induced tumors and induces tumor progression to cytokine-independent growth. In contrast, loss of Gfi1 in hematopoietic stem cells induces cell cycle progression and eventual bone marrow failure; implicating Gfi1 as a tumor suppressor in such cells. Gfi1 null mice have no mature neutrophils, and we have identified humans with Severe Congenital Neutropenia (SCN) and Non-Immune Chronic Idiopathic Neutropenia of Adults (NI-CINA) bearing mutations in Gfi1. Interestingly, such patients are at increased risk for the development of myelodysplastic syndromes and acute myeloid leukemia. We have recently generated the first mouse model of Severe Congenital Neutropenia through the expression of mutant Gfi1 proteins in primary murine hematopoietic cells. Moreover, we are utilizing mouse models of human cancer to assess the risk of Gfi1 mutant humans for the development of acute myeloid leukemia.

Our lab is primarily interested in molecular factors that control the decision between tolerance and immunity within T lymphocytes. We use staphylococcal enterotoxins, recombinant vaccinia viruses, lymphocytic choriomeningitis virus and MHC tetrameric reagents as tools to study antigen -specific T cell responses. Our interest in tolerance centers on regulation of mechanisms that control the survival and death of activated T cells in vivo, namely Bcl-2 and its antagonist Bim. We are also interested in the manipulation and regulation of antigen-specific T cell responses via novel vaccine strategies to either induce tolerance or enhance immunity. Finally, we are interested in mechanisms underlying sex-based differences in T cell responses and how these differences relate to autoimmune disease.

Kasper Hoebe, PhD
focuses on mechanistic analysis of pathways of innate immune activation and the mechanisms underlying NK cell and CD8+ T cell development and cytolytic effector function, using forward genetic approaches. His discovery of an “endogenous adjuvant” pathway mediated by NK cell killing has led to research aimed at exploiting the knowledge obtained on NK cell-driven adaptive immune responses for the generation of new, safer vaccine approaches.

Jonathan D. Katz, PhD, focuses on autoimmune diabetes research. Autoimmune diabetes, also known as type 1 diabetes (T1D), is the most common pediatric autoimmune disease. Roughly 1/250 individuals develop T1D in the United States.There is currently no cure for T1D and the only treatment is daily exogenous insulin replacement therapy. Many T1D patients eventually develop secondary complications, such as hearth disease, blindness, peripheral neuropathy and renal failure.
Dr. Katz's work focuses on the role that autoreactive T lymphocytes play in the disease process. His lab interested in (1) the control of autoreactive T cells via central and peripheral tolerance, (2) the role NKT cells play in regulating autoreactive T cells, and (3) the role dendritic cells play in activating and regulating autoreactive T cells in T1D.
Most of his work uses the non-obese diabetic (NOD) mouse strain that spontaneously develops T1D with remarkable similar to the T1D seen in human patients. The availability of the NOD strain has allowed us to take a modern, reductionist molecular and cellular immunology approach to understanding the mechanism(s) and genetics underlying T1D susceptibility and disease progression. His lab makes extensive use of knockout, transgenic, regulated gene expression, targeted ablation, cell transfer and genomic studies the progression and regulation of T1D in the NOD mouse.

Ian P. Lewkowich, PhD
investigates the factors that drive the development of severe allergic asthma, with a particular focus on the molecular mechanisms through which Th17 cytokines enhance IL-13 signaling, the regulation of the asthmatic response through the PD-1/PD-L axis and the mechanisms of the well-described maternal influence in inherited asthma risk.
While Th2 immune responses are central to disease pathology in allergic asthma, there is a growing understanding that the Th2 paradigm is not sufficient to explain the entire spectrum of disease severity. Indeed, there is growing belief that severe disease may be driven by a different process than mild to moderate disease.
Using a mouse model of allergic asthma in which one strain develops a phenotype characteristic of mild asthma (C3H/HeJ), and others develop a phenotype characteristic of severe disease (A/J), we have identified several novel mechanisms through which asthma severity is regulated. We have found that the development of severe allergic asthma is associated with a limited capacity of Tregs to limit pulmonary dendritic cell activity, enhanced capacity for antigen uptake by pulmonary myeloid dendritic cells, and the development of a mixed Th2/Th17 immune response. In contrast, C3H mice demonstrate increased Treg activity, preferential antigen uptake by pulmonary plasmacytoid dendritic cells, and an exclusively Th2-biased immune response. We are presently using the A/J versus C3H/HeJ mouse model of allergic asthma to tease out the mechanisms responsible the development of severe allergic asthma.

Sean R. Moore, MS, MD
is interested in the vicious cycle of childhood diarrhea and malnutrition in developing countries, with a current focus on the mechanisms of a promising glutamine-based oral rehydration and nutrition therapy. Dr. Moore studies the signaling pathways by which alanyl-glutamine promotes gut homeostasis and also collaborates with colleagues on the epidemiology and impact of early childhood diarrhea and undernutrition in impoverished settings.

Ardythe L. Morrow, PhD Director, Center for Interdisciplinary Research in Human Milk & Lactation
Director, Center for Interdisciplinary Research in Human Milk & Lactation
Human milk; child health and nutrition
Dr. Morrow received her MSc in nutrition from the University of the West Indies, Kingston, Jamaica (1980) and PhD in epidemiology from the University of Texas at Houston (1991). Since 1987 she has worked with colleagues in Mexico, Boston, and Houston on an NIH-funded program project on human milk immune protection against infectious disease.
She is currently Professor of Pediatrics at the University of Cincinnati College of Medicine and Cincinnati Children's Hospital Medical Center, where she founded and directs the Center for Epidemiology and Biostatistics that has 35 faculty and staff and a multi-disciplinary Human Milk Research Program that includes clinical and basic science investigators in eight divisions.
She has published extensively on breastfeeding promotion and human milk protection against infectious diseases. Her primary focus is on protection by human milk glycans and protection against infectious disease, but she has expanded her research to understanding the relationship between breastfeeding and chronic diseases. She has been an ad hoc reviewer for NIH on breastfeeding research and a technical advisor for international breastfeeding policy and programs for Gates Foundation, UNICEF, and WHO, is on the editorial board of the Journal of Human Lactation and the journal of the Academy of Breastfeeding Medicine. She is an elected member of the American Pediatric Society. She has over 100 publications, and is the primary author of the WHO monograph, Community-based Strategies for Breastfeeding Promotion and Support in Developing Countries (2004).
She has served as Chair of the Milk Club of the (American) Society for Pediatric Research for the past 4 years. In 1997, she received a Young Investigator award from ISRHML for her randomized trial of breastfeeding support (Lancet, 1999). She was co-organizer of the 2002 ISRHML international meeting in Mexico and is co-editor of the book Protecting Infants through Human Milk: Advancing the Scientific Evidence.
