Integration of human genetics and islet genomics to advance understanding and management of type 2 diabetes

www.ocdem.ox.ac.uk 

www.well.ox.ac.uk

Mark McCarthy is the Robert Turner Professor of Diabetes Medicine at the University of Oxford based at both Oxford Centre for Diabetes, Endocrinology and Metabolism and the Wellcome Centre for Human Genetics. His research group is focused on the identification and characterisation of genetic variants influencing the risk of type 2 diabetes and related traits, and on using those discoveries to drive biological inference and translational opportunities.
He has played a leading role in many of the major international efforts to identify the genetic variants that influence predisposition to type 2 diabetes including DIAGRAM, T2DGENES and GoT2D. These consortia have used genome wide association and sequencing approaches to identify over 400 genetic signals for type 2 diabetes. Equivalent efforts focused on diabetes-related traits, including obesity, fat distribution and birth weight have been similarly productive.
With collaborators, his group's activities are now increasingly focused on the exploitation of these discoveries to gain insights into the biological mechanisms underlying disease development. Integration of genetic association signals with genomic annotations derived from pancreatic islets and other diabetes-relevant tissues is providing robust insights into the molecular and pathophysiological mechanisms through which many of these signals operate.
This also makes it possible to use this information to open new translational opportunities through target validation, risk stratification and biomarker discovery.

LAURA C. ALONSO (USA)

ER Stress: Beta-Cells Rise to the Challenge

https://www.umassmed.edu/alonsolab/

Dr. Alonso earned a BA in biochemistry from Harvard University and an MD degree from the University of Pennsylvania. She completed a residency in Internal Medicine and a fellowship in Endocrinology and Metabolism, both at the University of Chicago. Her research training began with a 5-year postdoctoral fellowship with Elaine Fuchs in stem cell biology, starting at the University of Chicago and finishing at the Rockefeller University. She began her career as an islet biologist with a junior faculty position with Andy Stewart at the University of Pittsburgh, subsequently moving to the UMass Medical School in 2013. Her research is focused on beta cell regeneration, with two principal long-term goals: to understand the molecular mechanisms behind successful beta cell mass expansion in mice, and to identify the causes of failed proliferation in human beta cells. One current molecular focus of the lab is to identify the mechanisms behind a novel concept developed by the lab: linking insulin demand with beta cell proliferation via activation of the ER stress response pathways known as the unfolded protein response. A second focus is determining how the CDKN2A/B T2D risk-locus impacts beta cell mass and function. She is also strongly motivated by mentoring and developing young scientists, both clinically trained and basic researchers.

SEBASTIAN BARG (SWEDEN)

Assembly of the insulin granule exocytosis machinery Insulin- and glucagon granule behavior in type-2 diabetes

https://www.mcb.uu.se/res/groups/sb/

Sebastian Barg has a background in biochemistry and chemistry and a PhD in physiology (Lund U). After postdoc work at the Vollum Institute (Portland OR) and Imperial College London he started his own group at Uppsala University. The main interest is in the cell biology of hormone and neurotransmitter secretion, with a focus on the life-cycle of insulin-containing secretory granules. The lab studies exocytosis in pancreatic ß-cells and other islet cells using advanced light microscopy (TIRF, super-resolution and single molecule imaging) in combination with patch clamp electrophysiology. The aim is to quantitatively understand the release probability of individual granules both mechanistically (as the sequential assembly of the secretory machinery from its protein and lipid components) and in the physiological context of biphasic insulin secretion in health and type-2 diabetes.

MIRIAM CNOP (BELGIUM)   

Overview & Update on Collaborative Initiatives in Islet Cell Function & Diabetes: T2DSYSTEMS

https://www.ulbcdiabres.com/

Miriam Cnop's research focuses on pancreatic cell dysfunction and apoptosis in the pathogenesis of type 2 diabetes. Her team identified endoplasmic reticulum stress as a molecular mediator of free fatty acid-induced cell apoptosis. She has contributed to the discovery and study of several new forms of monogenic diabetes, where gene mutations affect cell endoplasmic reticulum stress, mitochondrial function and tRNA biology. These patients with monogenic diabetes can be considered as human knockouts and can provide us with insight into key biological pathways important for cell development, function and survival. To gain insight into the pathways of cell failure in these monogenic forms of diabetes and to test therapies, her team is differentiating patient-derived induced pluripotent stem cells into cells. This represents a highly relevant disease-in-a-dish model, opening a range of new research avenues.
She has published 90 papers that have been cited over 9000 times, with an H-index of 41.
Her work has been funded by the European Foundation for the Study of Diabetes, the European Union Framework Programmes 6 and 7, the Innovative Medicines Initiative and Horizon 2020, the National Ataxia Foundation USA, the Friedreich Ataxia Research Alliance USA, and the Belgian Fund for Medical Scientific Research.
The European Association for the Study of Diabetes awarded her work with a Rising Star Award in 2005 and the Oskar Minkowski Award in 2013.

https://www.diabetesgenes.org/

Sarah is a Wellcome Trust/Royal Society-funded Sir Henry Dale Fellow at the University of Exeter Medical School. She completed her PhD in 2007 under the supervision of Professor Andrew Hattersley and Professor Sian Ellard which investigated genotype/phenotype relationships in neonatal diabetes and congenital hyperinsulinism.
Sarah leads the congenital hyperinsulinism research group in Exeter and together with the monogenic diabetes team has provided genetic testing for over 4000 patients from over 100 countries around the world. Since arriving in Exeter Sarah has been involved in the discovery of 13 novel genes for monogenic disorders of insulin secretion and has led studies investigating genotype/phenotype relationships. This work has resulted in her publishing over 180 peer reviewed papers.
In 2014 Sarah led the discovery of activating germline mutations in the STAT3 gene in individuals with syndromic early-onset autoimmune diabetes. This work was published in Nature Genetics and the finding sparked her interest in monogenic autoimmunity. Sarah's current work focusses on the utility of clinical features and genetic risk scores to help differentiate rare monogenic autoimmune disease from more common polygenic 'clustering'. Her team are currently undertaking gene discovery studies, immuno-phenotyping and are focussed on improving and developing new variant calling bioinformatics pipelines to allow for in-depth interrogation of next-generation sequencing data.
In 2015 Sarah received the EASD-study group for the genetic of diabetes Rising Star Award and in 2018 was selected as a recipient of the G.B. Morgagni Silver Medal Young Investigator Award which recognises exceptional research in the field of metabolic disease.

DAVID HODSON (UK)

Using conditional approaches to understand alpha-, beta- and delta-cell functional subpopulations

http://www.birmingham.ac.uk/staff/profiles/metabolism-systems/hodson-david.aspx http://www.birmingham-nottingham.ac.uk/bn/compare/about.aspx  

David is Professor of Cellular Metabolism, Professorial Research Fellow and an early career researcher based at the Institute of Metabolism of Systems Research, University of Birmingham. Previously, he was a Diabetes UK RD Lawrence Fellow and Non-Clinical Lecturer at Imperial College London. David has particular interest in developing novel tools to understand beta and other cell function both in vitro and in vivo. Current research, using mouse genetics in combination with next generation optogenetics, focuses on understanding how immature beta cell subpopulations may exert disproportionate control over insulin release. Alongside this, we continue to contribute to the field of photopharmacology, which describes the precise spatiotemporal control of receptor, enzyme and ion channel function using exogenously-applied light-activated drugs. Recent targets include KATP channels, glucagon-like peptide-1 receptors, fatty acid receptors and L-type Ca2+ channels, all with relevance for the mechanisms underlying glucose homeostasis. Finally, we are harnessing the power of enzyme self-labelling technology to target drugs to G protein-coupled receptors in body compartments and specific cell populations through reversible covalent linkage. This concept, termed 'tethered pharmacology', may contribute to our understanding of GPCR signaling in health and disease by combining the speed of pharmacology with the precision of genetics. The overarching aim of our research is to use interdisciplinary approaches to open up new avenues of exploration in metabolism research.

CHRISTIAN Honoré (DENMARK)

Lessons from the StemBANCC consortium – Developing disease models of diabetes using induced pluripotent stem cell.

www.novonordisk.com

Christian Honoré was born in a suburban part of Copenhagen during the late seventies and spent most of his childhood dreaming of making it to the American basketball league NBA. Despite some early success in Danish basketball which he will be very happy to talk about, he was - for reasons still unclear to him - never drafted by an NBA team and instead turned his focus to his studies in biological sciences. He obtained his master degree in biochemistry from the University of Copenhagen and went on to study the complement system during his PhD at the University Hospital of Copenhagen. He then moved to Boston for a post doc in Professor Doug Melton's laboratory at the Harvard Stem Cell Institute. Here he was introduced to the fascinating world of pluripotent stem cells and how to differentiate these towards the pancreatic lineage. After two years in Boston he returned to Denmark for a post doc position at Novo Nordisk A/S as part of the innovative medicine initiative academia-industry partnership StemBANCC. The main objective of StemBANCC was to establish a well-characterized bank of iPSC lines derived from patients with disorders ranging from Parkinson's, Alzheimer and various forms of diabetes. Within StemBANCC, Christian worked closely together with academic and industry partners to characterize the differentiation of iPSC towards the pancreatic lineage and to establish disease models of various forms of diabetes using patient specific iPSC lines. After the end of StemBANCC, Christian joined Novo Nordisk A/S as a scientist and now dedicates his time to translating the potential of stem cells from the culture dish to the clinic. Outside the lab, Christian spends most of his time with his family but also with friends, either on a basketball court or at a bar table.

LIMOR LANDSMAN (ISRAEL)

Pancreatic Pericytes in beta‐cell development and function

 www.landsman-lab.com

Dr. Limor Landsman established her lab in Tel Aviv University in 2012. She received her Ph.D. from the Weizmann Institute of Science (Rehovot, Israel) in Immunology and continued to postdoctoral studies in the field of pancreas biology at UCSF. Her lab researches the role of the pancreas microenvironment in regulating pancreas development and function. Her findings to date indicate the continuous requirement of mesenchymal cells for pancreas organogenesis, through controlling proper proliferation rates and thus proper pancreas cellular composition. Her studies further indicate the pancreatic pericytes are required for beta-cell proliferation and function. Moreover, studies from her lab showed that diabetes-associated genetic alterations in pancreatic pericytes interfere with these cells ability to support beta-cell function, resulting in impaired glucose-stimulated insulin secretion. Thus, her research has highlighted a previously unappreciated role of pancreatic pericytes in glucose homeostasis and implicates abnormalities in the islet microenvironment as a potential cause for beta-cell dysfunction and diabetes progression. Her recent findings were published in leading peer-review scientific journals, including Nature Communications, PNAS, Diabetes, and PLoS Biology.

PATRICK MACDONALD (CANADA)

Connecting human islet cell functional and transcriptomic heterogeneity by combined patch-clamp and scRNA-seq  

www.bcell.org

Patrick completed his PhD at the University of Toronto in 2003, followed by postdoctoral research at Lund University and the University of Oxford. In 2006 Patrick established an independent research group in the Alberta Diabetes Institute (ADI) at the University of Alberta, where he is currently Professor of Pharmacology. Work from the group has focused mainly on understanding downstream mechanisms of excitability an exocytosis controlling insulin and glucagon secretion, and in particular the control of these processes by metabolic and receptor-mediated signalling. Current interests include understanding mechanisms of beta-cell functional adaptation, the control of spatial heterogeneity in granule fusion events across the cell surface, and signalling by neurotransmitters within the islet. The group also established a research-specific human islet isolation and distribution program, the ADI IsletCore, to process donor pancreas that is not used for clinical whole organ or islet transplant. This has improved access to human research islets, including from donors with diabetes, and now supports >80 groups in North America and Europe. The group is privileged to contribute to many collaborative efforts with investigators across the world, including efforts to link islet genomics and function; efforts to map islet cell heterogeneity in situ; and efforts to understand altered islet cell function in both type 1 and type 2 diabetes. Patrick has been fortunate to receive numerous awards for his work, most recently this year's Diabetes Canada/CIHR-INMD Young Scientist Award.

Irene is a Post-Doctoral researcher specialized in Molecular Genetics with expertise in the enhancer biology and non-coding variation leading to disease.
Irene completed her MRes of Reproductive Biology in Barcelona (Spain), where she studied the impact of in vitro culture on the DNA methylation patterns of preimplantation mouse embryos. Then, she moved to the UK, where she obtained a PhD in Molecular Genetics from the University of Birmingham. Her PhD work focused on transcriptional regulation, in particular, on the validation of human enhancers predicted by histone modification marks and bidirectional transcription in zebrafish embryos. During her PhD she also helped to develop a site-directed transgenesis system in zebrafish that reduces variability effects for functional testing of regulatory elements.
Irene moved to Barcelona as a PostDoctoral researcher in Jorge Ferrer's lab, where she has worked since 2014 between IDIBAPS (Spain) and Imperial College London (UK). She leads a project that assesses how the integrative analysis of 3D chromatin architecture in human islets and highly-refined epigenome maps can aid the interpretation of type 2 diabetes signals. Her long-term interest in the role of enhancers in human disease also prompted her to start modeling regulatory mutations leading to pancreas agenesis, shedding interesting insights into pancreas development.
In 2015 she was awarded with Marie Curie PostDoctoral Fellowship, funded by the European Commission to carry out her postdoctoral work. She has collaborated with international experts in the field of bioinformatics, gene regulation and genetics and was trained as a young scientist by the multidisciplinary EU-Funded Initial Training Network BOLD.

Zebrafish as a model for understanding beta-cell development

https://www.crt-dresden.de/research/research-groups/core-groups/crtd-core-groups/b-cell-biology-and-regeneration/ 

Nikolay Ninov is a group leader at the Center for Regenerative Therapies Dresden at TU-Dresden and the Paul Langerhans Institute Dresden. He completed his PhD at the University of Barcelona, during which he developed methods for high-resolution live-cell cell imaging of the remodeling of the Drosophila epidermis during metamorphosis. As a postdoctoral fellow, Nikolay joined the group of Didier Stainier at the University of California at San Francisco where he studied pancreas development and regeneration in zebrafish. He applied single-cell genetic manipulations and developed new transgenic lines to visualize non-invasively the proliferation and differentiation of beta-cells, which enabled to perform the first in vivo chemical screen for inducers of beta-cell proliferation. Currently, the Ninov's group focuses on understanding beta-cell heterogeneity during development and regeneration. This research combines single-cell behavior studies and gene expression analysis to define novel factors that confer different characteristics to beta-cells. Of particular importance is the ability to monitor with a very high spatio-temporal resolution the calcium dynamics of beta-cells in their native environment in the zebrafish pancreas, as well as to follow the development of individual cells marked in different colors using the Brainbow technology.

Epigenomics of diabetic islets

https://www.lunduniversity.lu.se/lucat/group/v1001241

My background includes a Master in Medical Science (major: Biomedicine), and a PhD in Biomedicine / Diabetes & Endocrinology, defended at the Medical Faculty at Lund University in 2010 (The role of genetic variation and DNA methylation in human glucose metabolism and type 2 diabetes). The following Post Doc position was mainly focused on the interplay between exercise and epigenetic changes in human tissues.
Continuing after two rounds of maternity leave, I am currently working as an Associate Researcher at the Lund University Diabetes Centre (LUDC), Sweden, in the Epigenetics and Diabetes unit. My research focus on epigenetic alterations in human tissues important in the pathogenesis of type 2 diabetes, mainly pancreatic islets, adipose tissue and muscle. Here we investigate the epigenetic signatures in tissues from healthy vs diseased individuals and investigate the interplay with genetic as well as environmental factors. We also explore altered DNA methylation in response to different external stimuli and the effect on different metabolic traits.
The last years we have also succeeded with whole genome bisulfite sequencing of human pancreatic islets in a case-control cohort, which can be used as a map of the human islet methylome, but also to understand gene regulation as well as a platform for exploring differences between health and disease.
Our findings propose a model where environmental factors act through epigenetic modifications, under the influence of genetic variation, on tissue specific gene transcription and consequently on metabolic phenotypes and risk of developing type 2 diabetes.

HOLGER A. RUSS (USA)

Designing Immune Privileged Human Beta Cells

www.russlab.com  

Dr. Holger A. Russ is an Assistant Professor at the Barbara Davis Center for Diabetes at the University of Colorado- Anschutz Medical Campus. Dr. Russ has been successfully working on different aspects of human beta cell biology, which has led to several original and important contributions to the fields of beta-, thymus- and stem cell- biology. He obtained his Ph.D. from Tel Aviv University in 2011 working in Prof. Shimon Efrat's laboratory on expansion of cadaveric human beta cells. He was the first to employ the Cre/lox system, commonly only used in transgenic animals, for lineage tracing of primary human cells in culture. With this novel approach, he could demonstrate that human cadaveric beta cells dedifferentiate into a proliferative state while maintaining a cell specific epigenetic memory that could be exploited to re-differentiate expanded beta cells. In addition, he collaborated with Drs. Bar-Nur and Benvenisty, to show the maintenance of a beta cell specific epigenetic memory after reprogramming beta cells into induced pluripotent stem cells. After completing his Ph.D. studies, Dr. Russ joined the laboratory of Prof. Matthias Hebrok, Director of the Diabetes Center at UCSF, where he established a rapid, large-scale, suspension culture system for the directed differentiation of pluripotent stem cells into functional beta cells in vitro. In parallel, he was part of the research team that demonstrate for the first time the generation of functional human thymic epithelial cells with the ability to support T-cell development from pluripotent stem cells. In fall 2016, Dr. Russ moved to Denver to establish his independent research program, focused on elucidating the underlying molecular and cellular events that result in the development of type 1 diabetes in patients, at the Barbara Davis Center for Diabetes.

From 1997 to 2001, she carried out postdoctoral research on the mechanisms glucose uptake into adipocytes and skeletal muscle cells with Dr. Jeffrey Pessin, then at the University of Iowa.

Dr. Thurmond initially joined the Biochemistry and Molecular Biology department at Indiana University School of Medicine in Indianapolis, Indiana, in the Summer of 2001, moving up through the ranks from Assistant to Full Professor by 2011, promoted to Associate Director of the Diabetes Group of the Herman B Wells Center for Pediatric Research. In July of 2015 she joined The Beckman Research Institute of the City of Hope in Southern California to serve as the Ruth and Robert Lanman Endowed Professor in Gene Regulation and Drug Discovery Research, and Chair/Head of the Department of Molecular & Cellular Endocrinology in the Diabetes and Metabolism Research Institute. Dr. Thurmond serves on editorial boards (Diabetologia, AJP, JBC, Frontiers, Endocrinology), grant review panels (NIH MCE and CADO, JDRF, ADA, AHA), and is recipient of several awards (Research Trailblazers Award of Indiana University; Davidson Award in Physiology from the University of Toronto).

John Todd FRS, FMedSci, FRCP Hons, PhD is Professor of Precision Medicine at the University of Oxford (until recently Professor of Medical Genetics at the University of Cambridge), Director of the JDRF/Wellcome Trust Diabetes and Inflammation Laboratory (DIL) in the University's Wellcome Centre for Human Genetics, and a Senior Investigator of the National Institute for Health Research. His PhD was in Biochemistry at the University of Cambridge. Todd researches type 1 diabetes (T1D) genetics and disease mechanisms with an aim of clinical intervention. Previously, Todd was Professor of Human Genetics and a Wellcome Trust Principal Research Fellow at the University of Oxford. Todd helped pioneer genome-wide genetic studies, first in mice and then in humans. He then went on to study the associations between mapped genomic disease-associated regions and phenotypes by founding and deploying the Cambridge BioResource. His research in genetics and diabetes has received several awards and prizes. In the latest phase of his research, to translate basic genetic and immunological knowledge to treatment and prevention, the DIL has now completed its first two mechanistic, statistically adaptive, drug dose-finding studies in T1D patients. This design and analyses have revealed several previously unknown effects of interleukin-2 (IL-2) on the human immune system, providing key information on the future possibility of using subcutaneous administration of ultra-low doses of IL-2 to preserve pancreatic islet beta-cell function to treat and prevent T1D. In Oxford the DIL is launching a programme to investigate which T1D risk regions affect beta-cell function and fragility. We are applying the latest single-cell, mass spectrometry methods, bioinformatics and statistical methods.

Todd has supervised 31 PhD students with three in progress. h-index 94, total citations over 38,000.
