Ina Stelzer, Ph.D., explores how the maternal immune system adapts to support a healthy pregnancy and how disruptions can lead to complications like preterm birth. Her lab identifies early immune changes linked to spontaneous preterm birth and investigates the role of the maternal brain in regulating immune responses. Stelzer uses advanced technologies like mass cytometry and spatial proteomics to map immune and molecular changes in pregnancy, integrating these data with transcriptomics and mouse models. Her team studies how antidepressants affect immune signaling during pregnancy and examines the impact of social and behavioral factors. These insights may reveal biomarkers and therapeutic targets for improving maternal and fetal health. Series: "Motherhood Channel" [Health and Medicine] [Show ID: 40773]

Michael J. Wilkinson, M.D., F.A.C.C., F.N.L.A., explores the science and clinical evidence behind intermittent fasting and its role in promoting cardiometabolic health. He explains how aligning eating patterns with the body’s natural circadian rhythms can improve weight, blood pressure, glucose regulation, and other risk factors, especially in individuals with metabolic syndrome or type 2 diabetes. Wilkinson highlights promising results from time-restricted eating studies conducted in collaboration with UC San Diego and the Salk Institute, where narrowing the daily eating window led to improved metabolic markers and potential benefits beyond weight loss. He also outlines practical tips for safely adopting this lifestyle approach and stresses the importance of ongoing research.

AI and genetic medicine are converging to transform how we diagnose, treat, and prevent disease. Gene Yeo, Ph.D., unites RNA biology with artificial intelligence to speed the path from genome sequencing to personalized RNA therapeutics. Advances in sequencing have reduced costs dramatically, making interpretation and translation into treatments the real challenge. Using deep learning and large datasets of RNA-binding proteins, Yeo predicts disease vulnerabilities and identifies therapeutic targets, including in neurodegeneration and muscular diseases. Alexis Komor, Ph.D., focuses on DNA, explaining human genetic variation—particularly single-nucleotide variants—and how genome editing technologies like CRISPR can target them. She highlights strategies to correct harmful mutations and explores precise, programmable interventions. Together, their research drives discovery and enables more effective, personalized therapies.

As part of the 2025 Developmental Disabilities Conference, Dr. Raul Gutierrez, Associate Professor of Pediatrics at San Francisco General Hospital, talks about supporting immigrant children. Series: "Developmental Disabilities Update" [Health and Medicine] [Show ID: 40619]

Dr. Robert Baron explores current strategies for treating obesity, emphasizing evidence-based approaches to diagnosis, lifestyle change, medication, and long-term weight maintenance. He explains the limitations of body mass index (BMI) as a diagnostic tool and highlights the importance of assessing both excess fat and its health consequences. He reviews dietary principles, including calorie reduction, avoiding added sugars, and the importance of sustainable habits over specific diet types. He also discusses the role of physical activity—particularly strength training—for preserving muscle and improving long-term outcomes. Baron evaluates weight loss medications such as semaglutide and tirzepatide, noting their benefits, side effects, and the need for continued use to maintain weight loss.

As part of the 2025 Developmental Disabilities Conference, Allen Friedland, Terri Hancharick and Jack Jadach talk about a collaborative approach to enhancing health in fitness centers. Series: "Developmental Disabilities Update" [Health and Medicine] [Show ID: 40613]

Dr. Robert Baron outlines major updates in type 2 diabetes care, emphasizing that blood sugar control alone does not significantly reduce cardiovascular risk, though it helps prevent microvascular complications. New guidelines now prioritize medications with proven cardiovascular and kidney benefits—GLP-1 receptor agonists and SGLT2 inhibitors—over traditional first-line therapy like metformin. Baron explains how these newer drugs not only lower blood sugar but also reduce the risk of heart attack, stroke, kidney disease, and heart failure, with added benefits such as weight loss. He also covers changes in screening, diagnosis, blood pressure goals, and individualized treatment strategies based on age, comorbidities, and patient preferences.

Sarah Banks, Ph.D. explores why Alzheimer's disease affects women differently than men, emphasizing distinct patterns in tau pathology, cognitive testing bias, and treatment response. She explains how women tend to show a rapid buildup of tau during early cognitive decline, which may contribute to their higher prevalence of Alzheimer's. Banks also highlights how common diagnostic tools may overlook symptoms in women and how approved treatments may offer less benefit for them. Her research at UC San Diego investigates key sex-based differences in risk factors, including sleep apnea, diabetes, and exercise. One study reveals that over 70% of participating women had undiagnosed sleep apnea. Another focuses on Black women, using blood biomarkers to identify overlooked risks and improve care.

Louise Laurent, M.D., Ph.D., presents new insights into placental biology using cutting-edge molecular and imaging technologies. As part of the NIH-funded Human Biomolecular Atlas Program, her research focuses on mapping the structure and function of the placenta across gestation. By combining bulk RNA sequencing, single-cell analysis, spatial transcriptomics, and imaging mass cytometry, Laurent and collaborators identify key differences in cell types and gene expression associated with pregnancy stages and labor. Her team highlights how specific cells like syncytiotrophoblasts and extravillous trophoblasts evolve over time and interact with maternal tissue. This integrated approach offers an unprecedented view of placental development and lays the groundwork for understanding reproductive health and disease.
