Sepsis arises from diverse and incompletely understood dysregulated host response processes following infection that leads to life-threatening organ dysfunction. Here we showed neutrophils emergency granulopoiesis drove a maladaptive during sepsis. We generated whole-blood single-cell multiomic atlas (272,993 cells, n = 39 individuals) of the sepsis immune identified populations immunosuppressive mature immature neutrophils. In co-culture, CD66b+ inhibited proliferation activation CD4+ T...
