RecruitingClinical trialDysfunctional Myelopoiesis and Myeloid-Derived Suppressor Cells in SepsisAdverse outcomes in surgical sepsis patients are secondary to dysregulated emergency myelopoiesis, and expansion of myeloid-derived suppressor cells. Here we propose to determine the underlying mechanisms behind the increased expansion of these leukocyte populations and the underlying mechanisms that drive inflammation and immune suppression.
