| Summary |
More than a century ago Metchnikoff defined neutrophils as small amoeboid-like cells that harbored peculiar polymorphonuclear structures. While since these early studies much has been learned about neutrophil physiology, mechanistic insight into neutrophil polymorphonuclear assembly remains rudimentary. Here we found that depletion of factors, that initiate the loop extrusion program, including NIPBL and MAU2, greatly accelerated the conversion of mononuclear to polymorphonuclear cells and orchestrated the induction of a neutrophil specific transcription signature. Remarkably, mere ablation of either NIPBL or MAU2 expression under conditions that normally prevent neutrophil differentiation, swiftly converted mono-nuclear into polymorphonuclear cells that expressed a neutrophil specific gene program. Depletion of NIPBL and MAU2 in neutrophil progenitors activated an armamentarium of neutrophil-specific enhancers to establish a neutrophil genome depleted for loop extrusion-induced looping. These observations indicate that extinction of the loop extrusion program converts mononuclear progenitor cells into polymorphonuclear cells and suffices to induce a neutrophil specific program of gene expression.
