Session 1. Opening Session by DVC Team (Lauren Kim, Allison Kim, and Dr. Jason Kim)

We had an exciting kick-off to Diabetes Virtual Summer Camp 2025 with today’s Opening Session. Lauren Kim (Founder, Program Director, and Webmaster) welcomed the interns from all around the world and shared the story of how this program began. Allison Kim (Associate Director and Director of Outreach) welcomed the interns and discussed the goals of the program and the objectives of the virtual sessions led by leading Experts in the field. Dr. Jason Kim (Advisor) welcomed the interns and discussed the program session format and Zoom policies. Our virtual internship program began in the summer of 2020, at the height of the COVID-19 pandemic, when our world was shut down, and as an effort to use the virtual platform to gather like-minded people, sharing our passion for science, medicine, and research. Since then, our program, now the 8th program of the Diabetes Virtual Camp, has gained new, far-reaching purposes. While scientific and medical conferences serve vital objectives in sharing discoveries, brainstorming with peers, and networking for collaborations, these conferences can be prohibitive to people in many ways, with costly registration fees, expensive travel costs, and even an intimidating environment, none of which applies to our program. Thanks to the American Diabetes Association and the Leona M. and Harry B. Helmsley Charitable Trust, the Diabetes Virtual Camp comes to you, in the comfort of your home or work, no matter where you are, near and far, without any fees, restrictions, or prejudice, as we have gathered today. While COVID-19 took away so many lives and affected other people’s livelihoods, it also changed our society, perhaps some for the better, as we learned that virtual learning has no limits, no boundaries, and no discrimination. When it comes to human health and diseases, understanding and sharing the right information is an important step towards saving lives. That’s why we are here, and that’s the goal of our program. For the next 2 weeks, we will have 13 sessions led by world-renowned clinicians and scientists who will share exciting discoveries from their impactful research, passionate stories about their lifelong care for patients, and inspiring stories of their path to success. We are thrilled to meet interns joining our virtual program from all around the world to better understand diabetes and inspire our next generation of physicians and scientists.

Session 2. Introduction to Diabetes by Dr. Jason Kim (University of Massachusetts Chan Medical School)

The Expert Session kicked off with “Introduction to Diabetes.” Dr. Jason Kim discussed the basics and pathogenesis of different types of diabetes and their diagnostic criteria, characteristics and etiologies of type 1 and type 2 diabetes, diabetic complications and comorbidities, the importance of glucose homeostasis and how insulin regulates glucose metabolism, insulin action in skeletal muscle and the liver, insulin secretion by pancreatic beta-cells, insulin resistance and pre-diabetes, and progressive events during the development of type 2 diabetes. Dr. Kim also discussed the endocrine role of the pancreas, insulin signaling, molecular pathogenesis of insulin resistance, the role of diets and exercise in preventing and managing diabetes, pharmacological management of diabetes, including the newest class of diabetes drugs, GLP-1 receptor agonists (e.g., semaglutide, exenatide, liraglutide), and our current research on the mechanisms by which tirzepatide regulates insulin sensitivity. Dr. Kim further discussed the role of obesity in type 2 diabetes, multi-factorial causes of obesity and why obesity rates continue to rise globally, different types of fat (white & brown fat), the paradox surrounding lipodystrophy and type 2 diabetes, molecular mechanisms of lipid-mediated insulin resistance, and the role of ectopic fat accumulation in insulin resistance. Dr. Kim ended the session with an insightful question posed by the late Dr. Denis McGarry, “What if Minkowski had been ageusic?”, opening doors to the important notion that while diabetes is manifested as altered carbohydrate metabolism, diabetes is causally associated with altered fat metabolism. The session ended with many insightful questions from our interns. We are thrilled to meet the interns joining our virtual program from all around the world to better understand diabetes, inspiring our next generation of physicians and scientists.

Session 3. Why You Shouldn’t Drink Sweet Things by Dr. Richard Lee (Harvard University)

The DVSC25 continued today with 2 incredible Experts, Dr. Richard Lee from Harvard University and Dr. Jose Florez from Harvard Medical School. Dr. Lee began by highlighting a disturbing trend of increasing fructose consumption in the U.S., particularly in liquid form, and this trend is associated with rising rates of metabolic diseases. This undesirable relationship is exacerbated by the addition of high fructose corn syrup (HFCS), an inexpensive and more common source of dietary sugar. Dr. Lee further discussed how fructose is metabolized by the intestine and liver and contributes to fatty liver disease. The HFCS has also been shown to enhance intestinal tumor growth in mice, possibly relating to the rising colon cancer rates in young adults with high consumption of liquid fructose. While sweetened beverages are shown to increase mortality, diet sodas are also associated with an increased risk of cardiovascular disease. Large liquid phase fructose loads may be worse because lower or slowly absorbed doses are converted to glucose in the intestine, likely a natural protective mechanism that we overwhelm with sugary drinks (evolutionary mismatch!). Bottom line, Dr. Lee recommends that it’s better to eat an orange than to drink orange juice. The session ended with many insightful questions from our interns.

Session 4. Precision Medicine in Diabetes by Dr. Jose Florez (Harvard Medical School)

The DVSC25 continued today with 2 incredible Experts, Dr. Richard Lee from Harvard University and Dr. Jose Florez from Harvard Medical School. Today’s exciting program continued with Dr. Jose Florez, who began by highlighting the heterogeneity of diabetes and an important finding from the Leif group showing how diabetic subjects could be clustered based on different clinical variables. Based on more than 700 genetic variants that are associated with a higher risk of type 2 diabetes, Dr. Florez presented the key trait and variant associations for 5 clusters. The Beta-cell cluster (e.g., HNF1A, MTNR1B) is associated with lower insulin but higher proinsulin, likely due to defects in insulin processing and/or secretion. The Proinsulin cluster (e.g., ARAP1, SPRY2) is associated with lower levels of insulin and proinsulin, likely due to defects in insulin synthesis. The Obesity cluster (e.g., FTO, MC4R) is associated with higher levels of insulin and BMI, likely due to insulin resistance. The Lipodystrophy cluster (e.g., IRS1, PPARG) is associated with higher insulin but lower BMI, likely due to insulin resistance secondary to fat redistribution/ectopic fat accumulation. Lastly, Liver/Lipid cluster (e.g., GCKR, PNPLA3) is associated with higher insulin but lower triglycerides, likely due to defects in lipid metabolism. Dr. Florez further discussed how these genetic clusters are differentially distributed based on ethnic background, possibly explaining why certain populations, such as Asians, develop type 2 diabetes despite lower BMI. In the end, Dr. Florez concluded that genetics can serve as anchor subtypes, which need to be informed by physiology, and pathophysiological subtypes may help identify pathways for precision medicine.

Session 5. Role of Social Determinants of Health in Diabetes Care by Dr. Enrique Caballero (Harvard Medical School)

The DVSC25 continued today with 2 inspirational Experts, Dr. Enrique Caballero from Harvard Medical School and Dr. Maureen Gannon from the Vanderbilt University School of Medicine. Dr. Caballero began with the basic triad in diabetes care, involving the healthcare system, healthcare provider, and patient. An important variable in diabetes care lies in the social determinants of health: socioeconomic status (education, income, occupation), neighborhood and physical environment (housing, built environment, toxic environmental exposures), food environment (food insecurity, food access, food availability, food affordability), health care (access, affordability, quality), and social context (social cohesion, social capital, social support). Dr. Caballero highlighted how the same area with high diabetes prevalence is the same area with high food deserts, indicating the importance of assessing food insecurity by healthcare providers. Dr. Caballero shared how he discusses with his patients about nutrition and food resources and guides their access to healthcare, offering comprehensive care necessary to tackle a multifactorial disease, such as diabetes. He also shared some creative approaches involving group medical visits where patients learn from each other and peer support intervention, involving the community. In all, Dr. Caballero summarized the multiple voices in diabetes care, extending beyond the basic triad and including government policies, social structure, educational institutions, professional organizations, patient advocacy groups, non-profit and community-based organizations, health insurance companies, and manufacturers of pharmaceuticals and devices.

Session 6.  “How Did I Get Here? One Scientist’s Journey” by Dr. Maureen Gannon (Vanderbilt University School of Medicine)

Today’s exciting program continued with Caroline Blanco, Senior Director of Professional Engagement, introducing her role for the American Diabetes Association and celebrating our global audience. This was followed by Dr. Maureen Gannon, our 2021 Expert, whose inspirational presentation still reverberates in the minds of many of our past interns, graciously returning to lead today’s session. Dr. Gannon began by sharing how “Everyone has had different life experiences and different paths. The path you walk shapes how you see the world and what you bring to the scientific process. She shared her humble beginning and the many twists and turns throughout her journey, some unexpected, yet she made the most out of her opportunities, leading her to success. What an inspiring story and priceless advice for our interns! She then discussed her lifelong research on studying different ways to increase the functional beta-cell mass, discovering several pathways that can increase beta-cell mass and stimulate beta-cell proliferation, highlighting the role of the Foxm1 transcription factor, which decreases with age. Her research found that FoxM1 activation enhanced beta-cell proliferation in aging mice, and FoxM1 also protected beta-cells against cytokines. She further showed how prostaglandin E2 receptors, EP3 and EP4, had opposing effects on beta-cell survival and proliferation. Dr. Gannon summarized how combined EP3 antagonism EP4 agonism preserves beta-cell mass and may prevent or delay type 1 diabetes.

Session 7.  “Preparing for a Career in Science and Medicine” by Dr. Jason Kim (University of Massachusetts Chan Medical School)

The DVSC25 continued today with more informative and exciting sessions from Dr. Jason Kim from the University of Massachusetts Chan Medical School and Dr. Vasilis Vasiliou from the Yale School of Public Health.
Dr. Kim began by illustrating how medical education is not for everyone due to its high cost, and should be pursued by one’s passion and strong interest. He noted how graduation from a medical school offers many different career paths. For high school and college students aspiring to be physicians, he discussed what they can do to prepare for medical school. He discussed the medical school application process and gave insightful advice on college activities/experiences and interviews. He also described the differences between the MD and MD/PhD dual programs. For medical students and residents, Dr. Kim shared a curriculum for the gastroenterology and hepatology fellowship training program at the University of Massachusetts Chan Medical School. He then discussed the importance of research in clinical training and elaborated on the investigative approach to science and medicine, including helpful tips on how to critically assess peer-reviewed research articles when searching for scientific information. For clinical fellows and early-career scientists and clinicians, Dr. Kim discussed what institutions look for in hiring new faculty, the tenure process, and professorship in academic medicine. He gave an example of what a day in the life of a professor would look like with respect to the administrative, teaching, clinical, and research roles for the institution and outside the institution at the national and international levels. Dr. Kim discussed what an early-career investigator should do to establish a productive research program and further shared insightful tips on writing an NIH grant (Grant Writing 101!). Dr. Kim ended his presentation by highlighting the University of Massachusetts Chan Medical School as a leading medical institution with outstanding patient care, education, and research.

Session 8.  “Redox Biology in Diabetes: Lessons from the Glutathione Spectrum” by Dr. Vasilis Vasiliou (Yale School of Public Health)

Dr. Vasiliou began with an introduction to the glutathione (GSH) spectrum as a double-edged sword in redox biology, describing GSH in diabetes and redox biology in metabolism. He discussed the important role of oxidative stress in human diseases, highlighting low GSH levels in the pathogenesis of fatty liver disease, and the protective role of the antioxidant system. Catalase is an antioxidant enzyme, and his earlier research found that the loss of catalase can promote prediabetic and obesity phenotypes. Dr. Vasiliou showed how a conditional deletion of glutamate-cysteine ligase catalytic (Gclc) subunit, the rate-limiting step in GSH biosynthesis, in the pancreas results in a severe diabetes phenotype at an early age due to loss of insulin-producing beta-cells and defects in glucose-stimulated insulin secretion. These effects were associated with oxidative stress in their islets. Using a tamoxifen-inducible approach to ablate the Gclc gene in later life, Dr. Vasiliou found that mice initially developed hyperinsulinemia that was followed by hyperglycemia and delayed diabetes phenotypes. The early preservation of redox balance despite reduced GSH levels may be due to compensatory mechanisms that are insufficient to maintain beta-cell function over time. In all, these exciting findings from Dr. Vailiou’s laboratory offer new insight into the role of GSH biosynthesis in maintaining beta-cell health in the adult pancreas.

Session 9.  “A Quest for Impact” by Dr. Robert Gabbay (Harvard Medical School)

The DVSC25 continued today with more inspiring and exciting sessions from Dr. Bob Gabbay from Harvard Medical School and Dr. Jean Schaffer from Harvard Medical School.
Dr. Gabbay began by asking our interns to describe what diabetes means to them in one word. Some of the answers from our interns were very insightful: “everywhere”, “long-term”, “epidemic”, “preventable”, “complex”, “life-changing”, “treatable”, “stressful”, “heterogeneous”, and “multifaceted.” Dr. Gabbay shared the story of his own journey, beginning with graduate education and research that led to medical school and clinical training with a growing desire to interact with patients. He then realized how he wanted to do more than just care for a patient and wanted to make an impact on population health, which became possible upon joining the Joslin Diabetes Center as Chief Medical Officer, overseeing more than 25,000 patients. He was able to make an even greater impact upon joining the American Diabetes Association as Chief Scientific and Medical Officer, leading the ADA’s global effort to drive discovery within the world of diabetes research, care, and prevention. In addition to the roles played by a researcher, clinician, and educator, Dr. Gabbay discussed how one can have an impact on diabetes through digital health, data science, drug discovery, device development, leadership, health writing, content creation, entrepreneurship, government, and policy. He ended with some helpful tips for our interns: reach out to people who are doing what you want to do someday, and find out the pros and cons of their work and what their day in the life is like. He also advised our interns to say “yes” to opportunities because one never knows where an opportunity may lead. A very perceptive advice indeed!

Session 10.  “Glucose Excess in Diabetes Pathogenesis” by Dr. Jean Schaffer (Harvard Medical School)

Dr. Schaffer began by outlining the role of hyperglycemia in type 1 and type 2 diabetes and the biochemical and genetic consequences of hyperglycemia. She highlighted how, despite recent advances in diabetes treatment, hyperglycemia remains common, as half of American adults with diabetes fail to meet HbA1C targets. This is critical since intensive insulin therapy and better glucose monitoring improve beta-cell function and reduce diabetic complications in people with type 1 and type 2 diabetes. Dr. Schaffer introduced how excess glucose can be metabolized through the aldose reductase pathway and the hexosamine pathway, leading to oxidative stress in the cells. Hyperglycemia can also increase advanced glycation end-products and lipid intermediates that are known to activate deleterious signaling cascades involved in diabetic complications. Dr. Schaffer discussed how hyperglycemia can regulate mRNA production by impacting chromatin confirmation and activity of transcriptional factors, one example being glucose regulation of ChREBP. She further discussed how not only does glucose stimulate insulin secretion by the beta-cells, glucose also increases insulin synthesis. Importantly, Dr. Schaffer’s laboratory found that chronic glucose inhibits glucose-stimulated insulin secretion by affecting many genes critical for glucose metabolism and insulin processing in the beta-cells at the level of mRNA translation. In all, Dr. Schaffer is elucidating the mechanism by which translational machinery, in particular ribosomes, may be affected by nutrients and developing novel therapeutics to interrupt glucotoxicity.

Session 11.  “Anti-Diabetic Effects of Estrogen and Testosterone in Women and Men” by Dr. Franck Mauvais-Jarvis (Tulane University School of Medicine)

After 2 weeks of exciting and inspiring sessions from the Experts, we have reached the finale of this year’s program. Dr. Mauvais-Jarvis began by illustrating how sex is a genetic modifier of human diseases. Estradiol and testosterone are key metabolic hormones in females, with estrogens playing a potent role in regulating insulin sensitivity and glucose homeostasis. Interestingly, all autoimmune disorders have a female bias in prevalence, except for type 1 diabetes, which may relate to estrogen’s protective effects on beta-cell function and survival in females. Estradiol was also shown to improve human islet engraftment and revascularization in insulin-deficient diabetic mice. Dr. Mauvais-Jarvis further discussed how estrogens promote degradation of misfolded proinsulin, thereby protecting insulin production and delaying diabetes. Targeting estrogen delivery selectively to the brain and beta-cells was achieved using GLP-1-E2 fusion peptides, conferring metabolic protection via GLP-1R and ERa. Dr. Mauvais-Jarvis also discussed polycystic ovary syndrome, a topic of high interest to our interns. He then discussed how testosterone is an anti-diabetic hormone in men, and the testicular-islet axis uses testosterone to enhance GLP-1 action. He further presented how a conditional loss of androgen receptor in beta-cells resulted in type 2 diabetes phenotypes in mice, implicating an important role of testosterone in beta-cells. Dihydrotestosterone was shown to increase GLP-1 action as the androgen receptor interacts with GLP-1 receptor, resulting in increased GLP-1-mediated insulin secretion by the beta-cells. Dr. Mauvais-Jarvis ended by discussing how sex differences in human islet cell transcriptomes predominantly affect sex chromosome genes. Very interesting science on our sex hormones as they relate to diabetes!

Session 12.  “Role of Inflammation in Type 2 Diabetes and Fatty Liver Disease” by Dr. Jason Kim (University of Massachusetts Chan Medical School)

The Closing Sessions continued with a more exciting session on type 2 diabetes and one of its major comorbidities, fatty liver disease, from Dr. Jason Kim. Dr. Kim began by introducing key discoveries made in early 2000 with IL-6 regulating insulin action and macrophages infiltrating adipose tissue in obesity, shaping an exciting new paradigm on the role of inflammation in type 2 diabetes. He discussed how IL-10 is a major anti-inflammatory cytokine in our body, and muscle-selective overexpression of IL-10 rescued mice from insulin resistance associated with obesity and aging. This was due to IL-10’s effects to suppress obesity and aging-mediated inflammation in skeletal muscle. Dr. Kim further highlighted how excess weight gain is a common issue in pregnancy, and offspring mice from high-fat diet-fed females developed insulin resistance with inflammation in the liver, supporting the important notion that excess weight gain during pregnancy may contribute to gestational diabetes and intergenerational risk for diabetes. He then discussed metabolic dysfunction-associated steatotic liver disease and how IFNg signaling in macrophages regulates obesity-mediated inflammation and insulin resistance in the liver. Mice with a conditional loss of IFNg signaling in macrophages were protected from diet-induced insulin resistance in the liver and fatty liver progression to inflammation and fibrosis, implicating macrophage IFNg signaling as a critical checkpoint in the development of metabolic dysfunction-associated steatohepatitis. Dr. Kim ended by briefly sharing some preliminary data from recent projects focusing on the molecular relationship between Alzheimer’s disease and type 2 diabetes.

Session 13.  Closing Session by the DVC Team (Lauren Kim, Allison Kim, and Dr. Jason Kim)

After 13 exciting sessions of the Diabetes Virtual Summer Camp 2025, we arrived at the Closing Session with Lauren Kim (Founder, Program Director, and Webmaster), Allison Kim (Associate Director and Director of Outreach), and Dr. Jason Kim (Advisor). Lauren and Allison expressed heartfelt appreciation to the DVSC25 interns for their growing passion and commitment to diabetes research, education, and care. Our interns asked outstanding questions using the Chat box following each session, demonstrating vital traits of an investigator, observation, and inquiry. Their dedication to learning was demonstrated through the pre-session Q&A period and echoed during the open-mic forum. Dr. Kim explained the process of requesting a program certificate for the Diabetes Virtual Summer Camp 2025.  The Diabetes Virtual Camp Team then administered electronic polls and surveys to collect important feedback from the interns about the program and explained the final program task to be completed within a week. Our interns didn’t want to leave as we held a final open-mic forum where the interns were unmuted to directly ask questions and provide more feedback on our program. The Closing Sessions ended with the final farewells to everyone as we remain hopeful that our program has met the goals to supporting the next generation of physicians and scientists and one day finding a cure for diabetes.  The Diabetes Virtual Camp looks forward to seeing you all in 2026!
