Ulf Ahlgren obtained a PhD in Medical Molecular biology at Umeå University, Sweden, in 1999, focusing on transcriptional regulation of endocrine cell differentiation in the pancreas. He obtained post-doctoral training at the Medical Research Council, Human Genetics Unit in Edinburgh, UK. His post-doctoral work focused on tissue interactions during development of the spleno-pancreatic region, and he contributed to the development of a novel imaging technology, optical projection tomography (OPT), which for the first time enabled mesoscopic imaging of mm-cm sized specimen with high molecular specificity and resolution. In 2002, he was recruited to Umeå Centre for Molecular Medicine UmU on a tenure track position, and he also received an Assistant ­ Professorship position from the Swedish Research Council.  In 2006, he became Associate Professor (Docent) in Medical Developmental Biology during which time his group presented the first 3D data sets of the complete b-cell distribution of the rodent pancreas. In 2011 he obtained a professorship in Medical Molecular Medicine at UCMM (now the Dept. of Medical and Translational Biology). At Umeå University, his lab pioneered the development/optimization of optical 3D imaging techniques for studies of the pancreas and, over the years the lab has presented novel information regarding aspects of pancreas biology ranging from normal pancreatic development and anatomy to e.g., disturbed proliferation, destruction, neogenesis, preservation and cellar re-programming of pancreatic cell-types. Based on such 3D data of the pancreas, his lab recently contributed the chapter on “the Pancreas” in the leading atlas of mouse anatomy. Today, the lab develops and implements approaches for mesoscopic 3D imaging to study the human pancreas, in health and disease, to better understand its anatomy/pathophysiology on an unprecedented scale at the acquired resolution.

Feyza Engin, Ph.D., is an Associate Professor at the University of Wisconsin-Madison, School of Medicine and Public Health. Dr. Engin obtained her Pharmacy and Master’s degrees from the Istanbul University School of Pharmacy. She received her Ph.D. degree in Molecular and Human Genetics from Baylor College of Medicine and completed her postdoctoral studies on Molecular Metabolism at Harvard University. Her postdoctoral work using pharmacological and genetic approaches provided the first direct link between beta cell ER stress and type1 diabetes (T1D) in preclinical models.

Over the past 10 years, studies from her lab focused on dissecting the function of the specific unfolded protein response (UPR) mediators in beta cells in T1D. Specifically, work from her lab demonstrated that during early stages of disease stress-induced transient dedifferentiation of beta cells could alter the diabetogenic activity of immune cells and protect NOD mice against T1D. In a follow-up study, they showed that under chronic stress conditions beta cells undergo transcriptional and translational reprogramming that induce a high degree of adaptive plasticity. Her laboratory’s recent work provided the first evidence for heterogeneity of beta cell senescence in T1D and induction of an immunosurveillance program triggered by beta cell UPR-deficiency in NOD mice. Dr. Engin’s current research focuses on identifying the role of beta cell stress responses, organelle dysfunction, and beta cell-immune cell crosstalk in T1D pathogenesis. She is the recipient of prestigious awards including NIH K01 award, Breakthrough T1D Career Development Award, and Shaw Scientist Award, among others.

Åke Lernmark has worked on type 1 diabetes etiology and pathogenesis since his Doctorate in Medicine (PhD) at Umeå University (1971) followed by research at the University of Chicago with the late Donald F. Steiner. He was director of research for the Hagedorn Research Laboratory and has had professorships and laboratories at the University of Washington in Seattle, WA and the Karolinska Institutet in Stockholm, Sweden. As a senior professor at Lund University in Sweden since 2009 his research is primarily focused on the genetic and environmental aetiology of beta cell autoimmunity and is the PI for The Environmental Determinants of Diabetes in the Young (TEDDY) site in Sweden. He and his colleagues described HLA DQ (1983) and the 64K protein (1981) (aka GAD65 1991) as the first autoantigen as well as the in vitro transcription translation radio binding assay (1992); still a gold standard to detect autoantibodies. An autoantibody first appearing against either insulin, GAD65, IA-2 or ZnT8 transporter is the first primary endpoint in the TEDDY study that have followed HLA DQ high-risk children from birth until 15 years of age. Omics analyses are used by the TEDDY study consortium to identify the mechanism by which exposure triggers autoimmunity against specific beta-cell proteins.

Dr. Raghu Mirmira obtained his MD-PhD degrees at the University of Chicago.  During his PhD training, he studied insulin-receptor interactions.  His work during this time set the foundation for the development of ultra-rapid- and ultra-long-acting insulins that are widely in use today.  Raghu subsequently completed his residency in Internal Medicine and subspecialty training in Diabetes and Endocrinology at the University of California at San Francisco. Raghu’s work in the early 2000s introduced the concept that chromatin states in beta-cells govern the transcriptional responses that regulate their glucose sensing and insulin secretory phenotypes. 

His subsequent work linked these transcriptional responses to mRNA translation through the metabolism of polyamines.  His recent research has advanced these concepts to disease pathogenesis, heralded by studies proposing that the molecular response of beta-cells to inflammatory signals initiates the autoimmune reaction in type 1 diabetes (T1D).  Raghu has extended his research to study the interaction between beta-cells and macrophages in diabetes, and he specifically defined the contribution of pathways mediated by polyamines, 12-lipoxygenase, and PERK in T1D pathogenesis.  Raghu’s larger impact includes leading the first-ever NIH-funded MD-PhD program (MSTP) at Indiana, leading two separate diabetes centers (Indiana and Chicago) to NIH funding, and training a generation of physician-scientists who have achieved academic leadership and NIH funding. Raghu was awarded the 2023 Albert Renold Award from the American Diabetes Association.

Abstract Presenters

As an Assistant professor at the University of Colorado Anschutz Medical Campus, I lead computational biology initiatives across multiple research programs at the Barbara Davis Diabetes Center, where I develop and implement advanced analytical approaches to understand the complexities of diabetes. Through long-term collaborations with experimental biologists, I bridge computational and biological insights to drive discoveries in beta cell biology and immune system dynamics in Type 1 Diabetes. My integrated approach spans multiple scales – from single-cell genomics to systems-level analyses – allowing me to explore connections across T cells, B cells, macrophages, and pancreatic islet endocrine cells. This cross-disciplinary perspective enables me to identify patterns and mechanisms that might be missed in isolated analyses.
