Title |
Single-cell transcriptome profiling reveals neutrophil heterogeneity in homeostasis and infection |
Organisms |
Homo sapiens; Mus musculus |
Experiment type |
Expression profiling by high throughput sequencing

Summary |
The full neutrophil heterogeneity and differentiation landscape remains incompletely characterized. Here we profiled more than 25,000 mouse differentiating and mature neutrophils using single-cell RNA sequencing to provide a comprehensive transcriptional landscape of neutrophil maturation, function, and fate decision in their steady state and during bacterial infection. Eight neutrophil populations (including the GMP population) were defined by distinct molecular signatures, including a new circulating mature neutrophil population highly expressing interferon-stimulated genes. The three mature peripheral blood neutrophil subsets arise from distinct maturing bone marrow neutrophil subsets, a novel mechanism that highlights the complex and precise regulation of neutrophil production. Neutrophil heterogeneity and differentiation are driven by both known and uncharacterized transcription factors. Neutrophils gradually acquire microbicidal capability as cells traverse the transcriptional landscape, representing an evolved mechanism for fine-tuned regulation of an effective but balanced neutrophil response. Bacterial infection reprograms the genetic architecture of neutrophil population, alters dynamic transition between each subpopulation, and primes neutrophils for augmented functionality without affecting overall heterogeneity. Bacterial infection-induced emergency granulopoiesis is mediated by augmented proliferation of early-stage neutrophil progenitors and accelerated post-mitotic maturation. In summary, single-cell transcriptomics enabled the reconstruction of neutrophil differentiation and maturation trajectories and uncovered neutrophil subpopulations, gene pathways, and regulators of neutrophil function and fate decisions. These data establish a reference model and general framework for studying neutrophil-related disease mechanisms, biomarkers, and therapeutic targets at single-cell resolution.

Overall design |
There are 10 mouse samples and 1 human sample. All relative organs consist of bone marrow (BM), peripheral blood (PB), spleen (SP), liver (LV) and peritoneal cavity (PC). 4 mouse control samples: BM sorted by cKit+ Gr1+; BM, PB, SP sorted by Gr1+. 6 mouse E. coli challenged samples: BM sorted by cKit+ Gr1+; BM, PB, SP, LV and PC sorted by Gr1+. 3 human control samples: PB sorted by CD33.
