Dr. Gwendalyn J Randolph's lab focuses on understanding and treating intestinal failure-associated liver disease (IFALD), especially in pediatric patients suffering from short gut syndrome and inflammatory bowel diseases. The research involves investigating how specific signaling pathways in the intestines and lymphatic systems contribute to these conditions and exploring potential therapeutic approaches using novel compounds. By combining studies in mouse models and piglet models, the lab aims to translate their findings into effective treatments for children.

Dr. Keith B. Hengen's lab at Washington University focuses on understanding the relationship between sleep and brain health, particularly in the context of neurodegenerative diseases like Alzheimer's. The research aims to uncover how sleep can help maintain optimal neural activity and prevent cognitive decline. By using innovative techniques to enhance sleep and its restorative effects, the lab seeks to identify new therapeutic strategies for combating neurodegeneration.

Dr. Jonathan Kipnis's lab at Washington University focuses on understanding how the immune system influences brain function and contributes to age-related cognitive decline and diseases like Alzheimer's. The research explores the role of meningeal lymphatics and immune cells in maintaining cognitive health, especially in older adults. The lab aims to develop innovative treatments that may enhance brain health by modulating immune responses.

Dr. Michael Benjamin Major's lab at Washington University explores innovative treatments for head and neck cancers, focusing on a protein called NRF2 that helps tumors resist radiation therapy. The team is testing new drugs that inhibit NRF2 to make these cancers more sensitive to radiation, aiming to improve patient outcomes. This research holds the potential to significantly enhance the effectiveness of existing cancer treatments and provide new therapeutic strategies for challenging cases.

Dr. Polina Lishko's lab at Washington University focuses on understanding how sperm function is regulated, particularly through a calcium channel called CatSper, which is critical for male fertility. The lab studies how environmental factors like temperature and certain chemicals influence sperm motility and capacitation—the process that enables sperm to fertilize an egg. Their research has important implications for addressing male infertility issues, such as those associated with varicocele, a condition that can impair sperm function.

Dr. Xiaoxiao Wan's lab at Washington University explores how certain molecules in pancreatic beta cells can trigger autoimmunity, specifically in type 1 diabetes. The lab focuses on understanding neoepitopes—modified pieces of proteins that can provoke harmful immune responses. By studying how these neoepitopes are formed and their role in autoimmune diseases, particularly type 1 diabetes, the lab aims to identify new targets for potential therapies and improve our understanding of disease mechanisms.

Dr. Hani Zaher's lab at Washington University studies how cells respond to stress by examining the ribosome's role in managing and repairing RNA during damage. They explore how ribosomes signal for quality control and stress responses, helping to maintain cellular health. Their research aims to better understand how these mechanisms support cellular functions and protect against diseases like cancer and neurodegeneration.
