Artem Barski, PhD, is interested in epigenomics and transcriptional regulation of gene expression. His PhD at the University of Southern California was focused on transcriptional regulation in osteoblasts. 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. Since his arrival to Cincinnati Children’s Hospital Medical Center in 2011, Dr. Barski is working on epigenomics of immunological memory. His laboratory is also developing both wet lab and computational approaches to the study of epigenomics and runs Cincinnati Children's Epigenomics Data Analysis Core.

Research Interests

Coagulation factors and inflammatory diseases

Research Interests and Focus:

1. Pancreatic ductal adenocarcinoma (PDAC) has the highest mortality rate of all cancers, is rapidly becoming the second leading cause of cancer deaths in the U.S., and is estimated to cost the health care system $2.4 billion each year. Patients with PDAC have a five-year survival rate of 7%, and that number drops to 2% for individuals with metastatic disease. Unfortunately, there has been little progress in shifting patient outcome over the past 40 years, highlighting the need for innovative approaches to define the molecular pathways that influence PDAC development. PDAC is typically initiated by acinar cells acquiring an activating mutation in the KRAS protooncogene, which causes cells to transition to a duct-like state known as acinar-ductal metaplasia (ADM). ADM progresses to pancreatic intraepithelial neoplasia (PanIN) lesions that develop into PDAC. A key transcriptional response to ADM/PanIN development is the dramatically increased expression of the physiological activator of the coagulation system, Tissue Factor (TF). Our research builds on a known relationship between pancreatic cancer and high-level activity of the blood coagulation system, but is unique in that it will define newly discovered mechanisms of crosstalk by which specific coagulation factors in the TME promote PDAC pathogenesis.

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 this 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 obesity, but any contribution to disease progression has remained largely undefined. Using a murine model of high fat diet (HFD)-induced obesity, this research program is testing the hypothesis that thrombin activity and fibrin deposition drive local inflammatory events promoting the progression of obesity and obesity-associated disease sequelae. 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 obesity pathogenesis by controlling local inflammatory processes that drive metabolic inflammation leading to fibrin(ogen)-mediated HFD-induced weight gain/obesity. This research has far-reaching implications for the treatment and prevention of all the downstream sequelae of obesity and even the development of diet-mediated weight gain itself.

Dr. Grimes has a broad background in hematopoiesis, molecular biology, and molecular oncology including modeling of hematopoiesis, myelopoiesis and leukemia. His work on the Growth factor independent-1 (Gfi1) transcriptional repressor protein has spanned the initial identification of Gfi1 in a model of leukemia and the role of Gfi1 in normal myeloid biology, to the identification of GFI1 mutations in patients with severe congenital neutropenia (SCN) and non-immune chronic idiopathic neutropenia of adults (NI-CINA). His work utilizes Gfi1 as a molecular probe to understand both normal myeloid development and innate immune action, as well as marrow failure and transformation.

Visit the Herr Lab.

Andrew Herr, PhD, is an associate professor in the Division of Immunobiology and Center for Systems Immunology, with an affiliate appointment in the Division of Infectious Diseases at Cincinnati Children's within the UC Department of Pediatrics. Dr. Herr completed his thesis work in molecular biophysics from Washington University in St. Louis, and completed his postdoctoral work in structural immunology at the California Institute of Technology as a Damon Runyon Research Fellow. He was recruited to the University of Cincinnati College of Medicine as an Ohio Eminent Scholar in Structural Biology before moving to Cincinnati Children’s Hospital.

Dr. Herr solved the first structure of a human IgA1 antibody bound to its cognate Fc receptor while at Caltech, and his lab has continued to study antibodies and immune receptors implicated in autoimmune diseases. In addition, the lab is studying a family of related collagen-specific immune receptors such as glycoprotein VI, which activates platelets upon exposure to fibrous collagen. The Herr lab also studies mechanisms of bacterial pathogenesis. Specifically, they discovered the zinc-dependent mechanism of intercellular adhesion in bacterial biofilms formed by Staphylococcus epidermidis and S. aureus. Biofilms are specialized bacterial colonies that are highly resistant to antibiotics and immune responses, so developing novel therapies to prevent biofilm formation is of high importance.

Before joining the faculty at Cincinnati Children's within the University of Cincinnati College of Medicine, Dr. Herr was an Ohio Eminent Scholar in Structural Biology at the University of Cincinnati College of Medicine and served as an associate director of the Cincinnati Medical Scientist (MD/PhD) Training Program. Dr. Herr received the 2014 Emerging Entrepreneurial Achievement Faculty Award from UC for his work to commercialize a novel anti-infective therapy based on his lab’s research.

Kasper Hoebe, PhD

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.

Dr. Huang’s studies have been focused on the activation and function of T cells in infectious and inflammatory diseases. During his postdoctoral training with Ted Hansen at Washington University, he started understanding the activation mechanism of innate-like T cells, specifically the mucosal-associated invariant T cells (MAIT) that are restricted by MHC class I like molecule MR1. He generated three major findings including the requirement of an antigen for MAIT cell activation (J Biol Chem, 2005), endocytic pathway of MAIT cell antigen loading (J Exp Med, 2008), and innate-like recognition of MR1 antigen complex by semi-invariant MAIT T cell receptor (PNAS, 2009). These findings supported the hypothesis that MAIT cells bear a rapid innate-like activation mechanism able to uniquely regulate mucosal diseases (Nat Immunol, 2007 review) and further inspired the discovery of MAIT cell protection against mycobacterial infection (Nat Immunol, 2010). As the lipid-responding T cells also show similar innate-like activation features, Dr. Huang’s additional training with Branch Moody at Harvard Medical School helped him establish a metabolomic platform and its applications to the antigens presented by MHC class I like CD1 proteins for the activation of lipid-responding T cells. These studies firstly revealed that the CD1b scaffold lipid diacylglycerol facilitates the presentation of the antigen mycobacterial glucose monomycolate to activate T cells from human tuberculosis (PNAS, 2011). Further collaboration using his metabolomic platform has discovered that mycobacterial and host lipid antigens were able to activate CD1c and CD1a-restricted T cells (J Exp Med, 2013, Nature Immunol, 2013).

Dr. Huang is extending the studies on the activation mechanisms and antigen structures of innate-like T cells particularly to the settings of mycobacterial infection, gut inflammation, and environmental exposure.

Immunology; autoimmunity; type 1 diabetes

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 is 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 similarity to the T1D seen in human patients. The availability of the NOD strain has allowed the lab to take a modern, reductionist molecular and cellular immunology approach to understanding the mechanism(s) and genetics underlying T1D susceptibility and disease progression. Dr. Katz's 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.

Research Interests

Genetics; bio-informatics

A large portion of Dr. Kaufman's research career has been on the genetics of systemic lupus erythematsus. Their work has screened 10's of thousands of lupus cases and controls with millions of polymorphic markers. This work has resulted in the identification, replication and/or fine mapping of over 70 genetic associations with systemic lupus erythematsus.

Recently, they have taken advantage of next generation DNA sequencing to identify variants that directly cause disease. They have developed a number of bioinformatic pipelines that can be applied to any phenotype. These automated pipelines are part of the Cincinnati Analytical Suite for Sequencing Informatics (CASSI) which has been applied to more than 20 different diseases and provides a list of candidate causative variants that lead to disease.

Raphael Kopan, PhD, and his lab have the long-term goal of organogenesis in vitro. They focus their efforts on Notch signaling as their lead into mechanistic understanding of tissue diversity using genetic engineering, embryology and single cell profiling. They interrogate the mouse embryo to address critical questions regarding the circuit logic of Notch signaling in mammalian organogenesis and its integration in larger signaling context.

Raphael Kopan, PhD, who is a professor of developmental biology at Cincinnati Children's Hospital Medical Center within the University of Cincinnati College of Medicine, has carried out seminal work in the field of Notch biology. This work has, and continues to have, an enormous impact on our understanding of normal tissue development and renewal, Alzheimer's disease and cancer-related research. In deciphering the mode of Notch activation and demonstrating the use of inhibitors to modulate Notch activity, Dr. Kopan's work laid the groundwork for the therapeutic use of γ-secretase inhibitors in the treatment of cancers, currently in clinical trials. His current interests in organogenesis are focused on two modular organs - skin and kidney - in which his group is trying to understand how interplay among the same seven pathways results in activation of distant programs. Dr. Kopan's work has resulted in 120 scientific articles as of 2013. He is the co-inventor of one patent, and he has served on scientific advisory boards as well as being a consultant to the pharmaceutical industry.

Genetic basis of lupus; genetic basis of eosinophilic esophagitis; immunological mechanisms mediating genetic association with disease

Visit the Kottyan Lab.

For the past decade, many geneticists have approached genetic analysis with the idea that they simply need to increase statistical power by enlarging the sample size (e.g. ~100,000 person height GWAS) and assess enough loci in order to find the “genes” associated with a disease. Unfortunately, clinicians can do relatively little with this type of correlative genetic information. Dr. Kottyan recently lead a genome-wide association analysis of eosinophilic esophagitis in which they went beyond the identification of nine new risk loci and identified the molecular, tissue-specific mechanisms through which genetic variants at the CAPN14 locus increase risk of disease.

During her post-doctoral fellowship, she optimized statistical modeling strategies using genetic data from large multi-ancestral cohorts to identify candidate genetic causal variants through complementary frequentist and Bayesian approaches. In genetic analysis, it is easy and even tempting to make a story out of a genetic variant that seems important. Using two types of statistical analyses on multiple cohorts of different ancestry helps to avoid the misplaced attribution of causality. Instead, Dr. Kottyan’s group develops a short list of variants that are most statistically likely to be causal before they start biological or functional analysis. Once identified, the group predicts and confirms biological phenotypes that are affected by the risk variants.

Immunology; asthma

Visit the Lewkowich Lab.

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.

Dr. Mersha is currently an associate professor at the Cincinnati Children’s Hospital Medical Center and University of Cincinnati, where he leads the Population Genetics, Ancestry, and Bioinformatics (pGAB) Laboratory. Dr. Mersha’s research combines quantitative, ancestry and statistical genomics to unravel genetic and non-genetic contributions to complex diseases and racial disparities in human populations, particularly asthma and asthma-related allergic disorders. Much of his research is at the interface of genetic ancestry, statistics, bioinformatics, and functional genomics, and he is interested in cross-line disciplines to unravel the interplay between genome and envirome underlying asthma risk. Dr. Mersha’s laboratory carries out both computational and applied data analysis projects, including the development of statistical and genome informatics tools that enable multiethnic admixture, genome-wide association and omics integration studies of complex biomedical traits, including asthma. He is a recognized expert in the field of genetic ancestry, race, admixture mapping and mining functional genomic databases related to complex diseases.

Dr. Mersha’s team contributions include the development of: 1) AncestrySNPminer, the first web-based bioinformatics tool designed to retrieve ancestry-informative markers (AIMs) with divergent allele frequency/selection pressure from the genomic databases (Cincinnati Children's Hospital Medical Center Technology disclosure #: 2011-1105). As of March 15, 2018, over 18,506 registered users world-wide have freely accessed this tool; 2) GENEASE, an integrative omics tool used to filter functionally important variants from publicly available ‘omics’ databases such as ENCODE, GTEx, and Epigenome Roadmap; 3) SAGE, a shared ancestry genetic etiology miner tool among complex diseases and multiple racial ancestry populations; 4) AdmixPower, a power and sample size estimation for mapping genetic loci in admixed populations.

Dr. Mersha has received multiple awards and honors including 1) 2017 Faculty Research Achievement Award from Cincinnati Children’s Hospital Medical Center, 2) 2017 African Professionals Network (APNET) Business & Professional Achievement Award, and 3) Keystone Symposia Early Career Investigator Award. Dr. Mersha has been invited to speak at national and international conferences, and moderated a panel on use of ancestry, race and ethnicity in biomedical research at a recent NIH conference. In 2017, he was invited to speak at the NHLBI funded PRIDE meeting on the topic of “My Road to Success.” Dr. Mersha organized and led an “Omics” workshop at the 2017 AAAAI annual conference entitled: “Omics-based bioinformatics/system biology approach to allergic disorders”. Dr. Mersha is a Program Faculty member of the Immunology Graduate Program, Biomedical Informatics (BMI) Graduate Program Faculty, Medical Scientist Training Program (MSTP) Faculty, and Systems Biology Program Faculty, and offer lectures to graduate students at the University of Cincinnati and Xavier University.

A major focus of Dr. Mersha's laboratory has been ancestry analysis, gene-environment interactions and functional genomics of asthma and asthma-related allergic disorders. Specific ongoing research projects include the following: 1) admixture mapping to localize asthma liability genes in admixed population; 2) interaction of asthma risk variants and environmental exposures that shape racial disparities; 3) identifying genetic/regulatory networks to identify potential functional variants associated with asthma and atopic dermatitis using whole transcriptome RNA-seq profiling; 4) investigating the role of microbiome and epigenome on asthma pathogenesis among immigrants; 5) developing web-based bioinformatics tools designed to leverage and integrate multiple omics from public databases (e.g., ENCODE, Epigenome Roadmap, GTEx, GEO and 1000 Genomes Project). His career goals are to develop a program that will lead to an in-depth understanding of the complex interplay between genomic variations and environmental exposure risk factors in the etiology of complex diseases, including asthma.

Research Interests

Systems biology; computational immunology; immuno-engineering; network inference

Our research goal is immuno-engineering: to alter the behavior of specific immune cell populations in disease contexts (autoimmune disease, organ transplant, and cancer) without compromising the body’s homeostatic immune function (e.g. defense against pathogens). Thus, it is critical to develop a nuanced understanding of how different immune cells sense and respond to environmental cues across the body, in both physiological and disease settings. To this end, our lab’s major focus is reverse-engineering the underlying logic of immune cells (molecular networks that drive cellular responses) from high-dimensional molecular measurements of immune cells in action (sensing and responding to perturbations, disease conditions, etc.).

The lab’s focus is transcriptional regulatory network inference, modeling gene expression as a function of transcription factor activities, from gene expression and measurements of chromatin state. Chromatin accessibility measurements by ATAC-seq, together with transcription-factor DNA-binding preferences (motifs), can be used to broadly profile potential transcription factor binding events in relatively small populations of cells. Thus, we have used ATAC-seq with RNA-seq to enable de novo inference of transcriptional regulatory networks in physiological settings where sample material is limiting (e.g., intestinal immune cells in response to microbial/genetic perturbations). To date, most of these efforts have been in mouse models, as it is generally not possible to obtain sufficient sample material for similar experimental designs in human. To build human immune cell models, we are developing multi-task learning approaches to leverage evolutionarily conserved relationships and borrow statistical power from mouse datasets for inference in human. We are also developing methods to enable transcriptional regulatory network inference in very rare cell populations, as measured from single-cell RNA-seq experiments.

Immunology; innate immunity; macrophage biology; amino acid metabolism; intracellular pathogenesis

Dr. Qualls completed his undergraduate work in 2002, receiving his BA summa cum laude in biology from Thomas More College in Crestview Hills, KY. He then joined the laboratory of Don Cohen, PhD, in the Department of Microbiology, Immunology, and Molecular Genetics at the University of Kentucky, where he studied the role of macrophages and dendritic cells during the development of inflammatory bowel disease. After defending his thesis and receiving his PhD in 2007, Dr. Qualls began his postdoctoral training with Peter Murray, PhD, in the Department of Infectious Diseases and Immunology at St. Jude Children’s Research Hospital in Memphis, TN, where his research helped to define the functional plasticity of macrophages in response to infection and cancer. During his postdoctoral training, Dr. Qualls received a Ruth L. Kirschstein National Research Service Award and actively participated as vice chair of mentoring activities within the Postdoctoral Association Council and as a member of the Education Programs Committee.

Dr. Qualls’ long-term goals are to understand the interplay between nutrition, metabolism, and immune regulation during anti-pathogen defense. He has focused on how macrophages use the amino acid, L-arginine, to combat intracellular pathogens. As a starting point to appreciate broader principles of immunity and metabolism he established a map of L-arginine metabolism at the transcriptomic and metabolomic levels. His laboratory now uses this map to dissect how L-arginine generates anti-microbial effectors, how this pathway is regulated, and how microbes can hijack the pathway. His current research has two complementary tracks that retain initial focus on L-arginine metabolism in macrophages, but will eventually broaden into larger issues concerning metabolism in immunity.

The Qualls laboratory is currently addressing the provocative role of L-arginine biosynthesis from L-citrulline during intracellular infection, how this mechanism is regulated at the cellular level (predominantly in macrophages and T cells), and the mechanism(s) of L-arginine/L-citrulline-mediated immune cell function. While greatly unexplored, this pathway of amino acid recycling and utilization is vital as mice deficient in L-arginine biosynthesis, compared to normal mice, lack efficient control of M. tuberculosis infection.
