Dr. Deng’s research focuses on the mechanisms underlying immune dysregulation during sepsis and trauma. Major areas of emphasis in her lab include the role of DNA-sensing in innate immunity and the immunoregulatory role of fibroblastic reticular cells.

Dr. Deng’s lab is focused on understanding the molecular mechanisms of how DNA-sensing pathways regulate the pathogenesis of sepsis and trauma in a cell type-specific manner. Dr. Deng’s lab has found that experimental therapies in mice using Tlr9-deficient FRCs have successfully improved the therapeutic efficacy of FRC-based therapy by reducing mortality from an intra-abdominal infection model (Xu et al. JCI 2019). Her team will continue studying how cell-specific DNA-sensing controls the body’s response to overwhelming inflammation. The findings from these studies will identify ways to improve the effectiveness of experimental cell-based therapies, which will help us move closer to finding new treatments for sepsis in humans that will reduce morbidity and mortality.
