abstract = {Human polymorphonuclear-myeloid-derived suppressor cells
(PMN-MDSCs) consist of circulating low-density neutrophils
(LDNs) characterized by the ability to inhibit T-cell
responses. In previous studies, we demonstrated that the
mature fraction of PMN-MDSCs (i.e. mPMN-MDSCs) exerts more
potent immunosuppressive functions than its immature
counterpart. More recently, we defined a specific gene
signature of mPMN-MDSCs from cancer patients and
G-CSF-treated donors (GDs) by bulk RNA sequencing (RNA-seq)
experiments. In this study, by performing single-cell
RNA-seq (scRNA-seq) experiments of circulating mPMN-MDSCs
from non-small cell lung cancer (NSCLC) patients, we
identified a major scRNA-seq cell cluster (arbitrarily named
NSCLC c6) specifically displaying immunosuppressive and
protumor transcriptomic features. Then, by analyzing
publicly available scRNA-seq datasets from human
tumor-associated neutrophils (TANs), we uncovered three TAN
clusters (arbitrarily named TAN c6-c8) that were found to
share with NSCLC c6 several common genes and transcription
factor (TF) regulons associated with response to hypoxia,
positive regulation of angiogenesis, and metabolic
reprogramming. Furthermore, by performing scRNA-seq
experiments of GD mPMN-MDSCs, we uncovered four scRNA-seq
cell clusters (arbitrarily named GD c4-c7) that were
enriched for the same genes and pathways characterizing
NSCLC c6 and TAN c6-c8 cells. Altogether, these data uncover
that human circulating mPMN-MDSCs and TANs from different
cancer types share scRNA-seq cell clusters with
transcriptomic similarities, supporting the notion that they
might be strictly related.},
