Uncovering common transcriptional features shared by mature PMN-MDSCs and tumor-associated neutrophils in humans

ABSTRACT: In this study, we performed single-cell transcriptomic profiling of mature PMN-MDSCs (mPMN-MDSCs) from non-small cell lung cancer (NSCLC) patients and identified a distinct cell cluster (NSCLC c6) exhibiting immunosuppressive and protumor features. Comparative analysis with publicly available single-cell RNA sequencing (scRNA-seq) datasets of tumor-associated neutrophils (TANs) revealed shared transcriptomic features between the identified NSCLC mPMN-MDSC and TAN clusters. These transcriptomic features included the expression of common genes, activation of the hypoxia signaling pathway, and metabolic reprogramming. Additionally, scRNA-seq analysis of mature immunosuppressive neutrophils from G-CSF-treated donors (GDs) – which are a reliable model of circulating mPMN-MDSCs - demonstrated similar dysregulation of hypoxia and metabolic pathways, further reinforcing the existence of transcriptomic similarities between circulating mPMN-MDSCs and TANs.

10x Single-cell Sequencing for Smad3 wild-type and knockout neutrophils

Project description:The role of neutrophils in tumor is still controversial and largely unknown. We previously identified an anticancer tumor microenvironment from mice lacking Smad3, but the underlying mechanism is still largely unclear. Interestingly, depletion of neutrophils largely suppressed the anticancer phenotype of Smad3-KO mice against syngeneic murine Lewis lung carcinoma (LLC). Here, we discovered that Smad3 is essential for promoting N1/N2 polarization of the tumor_x0002_associated neutrophils (TANs) in lung carcinoma. We found that Smad3 deficiency dramatically increased N1 TANs associated with an anticancer phenotype in mice and detected a negative correlation between Smad3 activation and anticancer N1 associated with a higher mortality of NSCLC. By conducting a neutrophil-specific single-cell RNA-sequencing, we uncovered that Smad3 is essential for completing the N1/N2 polarization of TANs, whereas N1 will be the dominated phenotype in the Smad3-KO TME by analyzing the developmental pathways of TANs with pseudo-time at transcriptome level. Mechanistically, direct binding of Smad3 on the developmental genes in neutrophils under cancer condition was evidenced by ChIP-sequencing at genomic level. Importantly, both neutrophil-specific and pharmaceutical inhibition of Smad3 effectively enhanced the anticancer activity of human and murine TANs, thereby suppressing the progression of lung carcinoma in vivo. Thus, Smad3 may represent a precision therapeutic target for enhancing the anticancer activity of TANs via blocking N1/N2 polarization in NSCLC. in C57BL6 (wild-type) and Smad3-deficient (Smad3-/- ) mice and submitted for cell encapsulation and library construction by Chromium controller with 5’ expression kit (10x genomics)

Myeloid-derived suppressor cells promote lung cancer metastasis

Project description:Myeloid-derived suppressor cells (MDSCs) suppress antitumor immune activities and facilitate cancer progression. Although the concept of immunosuppressive MDSCs is well established, the mechanism that MDSCs regulate non-small cell lung cancer (NSCLC) progression through the paracrine signals is still lacking. Here, we reported that the infiltration of MDSCs within NSCLC tissues were associated with the progression of cancer status, and were positively correlated with the Patient-derived xenograft (PDX) model establishment, and poor patient prognosis. Intratumoral MDSCs directly promoted NSCLC metastasis and highly expressed chemokines that promote NSCLC cells invasion, including CCL11. CCL11 was capable of activating the AKT and ERK signaling pathways to promote NSCLC metastasis through the epithelial-mesenchymal transition (EMT) process. Moreover, high expression of CCL11 was associated with a poor prognosis in lung cancer as well as other types of cancer. Our findings underscore that MDSCs produce CCL11 to promote NSCLC metastasis via activation of ERK and AKT signaling and induction of EMT, suggesting that the MDSCs-CCL11-ERK/AKT-EMT axis contains potential targets for NSCLC metastasis treatment.

Single-cell RNA-sequencing of tumor associated neutrophils and control peripheral blood neutrophils in a novel lung squamous cell carcinoma mouse model

Project description:Tumor-associated neutrophils (TANs) can be conditioned to become “N2” pro-tumorigenic neutrophils in the tumor microenvironment. TANs have been shown to acquire N2 features and promote multiple aspects of tumor growth in mouse models of many cancers, including non-small cell lung cancer. We developed a novel mouse model for lung squamous cell carcinoma (LSCC): Rosa26LSL-Sox2-IRES-GFP;Nkx2-1fl/fl;Lkb1fl/fl (SNL). SNL mice develop tumors with short latency of ~3 months and SNL tumors have high neutrophil infiltration similar to other LSCC mouse models. We employed this novel model and single-cell RNA-sequencing to profile TANs in SNL lung tumors in comparison to peripheral blood neutrophils (PBNs) from tumor-bearing SNL mice.

Whole genome expression profile of human decidual PMN-MDSC and autologous neutrophils in normal pregnancy

Project description:It is suggested that decidual polymorphonuclear myeloid-derived suppressor cell (PMN-MDSCs) are a group of activated suppressive neutrophils. Decidual microenvironment can facilitate circulating neutrophils with phenotypes and functions of PMN-MDSCs. The mechanism of PMN-MDSCs differentiation induced by decidual microenvironment has not been fully understood. Here we performed whole genome expression profile of 3 decidual PMN-MDSCs and autologous neutrophils from normal early pregnancy. Total RNA were extracted. The arrays were scanned by the Agilent Scanner G2505C. There were differences of gene expression pattern between decidual PMN-MDSCs and autologous neutrophils in early normal pregnancy.

Myeloid-derived suppressor cells exhibit distinct characteristics in bone marrow and blood of individuals with diffuse large B-cell lymphoma

Project description:Antitumor immune surveillance is the key feature of tumour progression and response to treatment in various malignancies, such as lymphomas. Myeloid derived suppressor cells (MDSCs) are bone marrow (BM)-derived cells with potent suppressive properties, implicated in T cell inhibition and tumour dissemination. In Diffuse Large B-cell Lymphoma (DLBCL), circulating MDSCs constitute the immunosuppressive tumor microenvironment, while the contribution of BM MDSCs in disease pathogenesis remains elusive. In the present study we aimed to evaluate both the frequencies as well as the molecular signatures of MDSCs in blood and BM from newly diagnosed DLBCL patients prior to treatment initiation and from age matched healthy donors. Circulating levels of total, monocytic (M-) and polymorphonuclear (PMN-) MDSCs were found increased in DLBCL compared to healthy control, while in DLBCL patients the BM MDSCs were significantly increased compared to blood. Transcriptomic analysis revealed significantly different molecular fingerprints to characterize circulating and BM M-MDSCs, implying that MDSCs exhibit their function with distinct mechanisms depending on the anatomical compartment. Despite that MDSC frequencies did not demonstrate any significant correlation with disease characteristics and outcome, our findings propose that gene expression profiling should be evaluated for their potential prognostic impact. Overall, the findings presented here, provide new insights in the immunosuppressive networks that operate in DLBCL and importantly propose new molecular mechanisms expressed by BM MDSCs which may be explored therapeutically.

RNA-seq analysis of sorted CD45+CD11b+Ly6G+ cells from C57BL/6 and Traj18-/- CRC samples and healthy controls

Project description:We performed RNA-seq analysis of tumor infiltrating neutrophils from C57BL/6 mice and iNKT deficient Traj18-/- mice to understand the role of iNKT cells in affecting phenotype and functions of neutrophils in CRC. We observed that TANs from B6 animals were enriched for transcripts of chemokines and inflammation as well as of immune suppression. These data suggest that iNKT cells condition the phenotype of TANs.

Tumor-associated neutrophils display a distinct N1 profile following TGFβ modulation: A transcriptomics analysis of pro- vs. antitumor TANs

Project description:It is becoming increasingly clear that tumor-associated neutrophils (TANs) play an important role in cancer biology, through direct impact on tumor growth and by recruitment of other cells types into the tumor. The function of neutrophils in cancer has been the subject of seemingly contradicting reports, pointing toward a dual role played by TANs in tumor progression. The existence of multiple neutrophil subsets, as well as phenotypic modulation of the neutrophils by various factors in the tumor microenvironment, has been shown. TGFβ plays a significant role in the determination of neutrophils' phenotype, by shifting the balance from an antitumor (N1) toward a more permissive (N2) phenotype. The full range of mechanisms responsible for the pro- vs. antitumor effects of TANs has not yet been elucidated. Therefore, the ability to identify the different neutrophil subpopulations in the tumor is critical in order to understand TANs evolution and contribution throughout tumor progression. Using a transcriptomic approach, we identified alternations in gene expression profile following TGFβ inhibition. We show that N1 and N2 TANs represent distinct subpopulations with different transcriptional signatures and both differ from naive bone marrow neutrophils. The analysis highlights a clear difference in pathways involved in neutrophil function such as cytoskeletal organization and antigen presentation, as well as alterations in chemokine profile, eventually affecting their effect on tumor cells and tumor growth. These data highlights several potential new pathways and mechanisms by which neutrophils can influence both the tumor cells and the adaptive immune system.

Expression profiling of lung neutrophils

Project description:Neutrophils are the most abundant circulating leucocytes and constitute an essential component of innate immunity. Although their role in cancer development is still poorly defined, pro- or anti-tumor properties have been attributed to tumor-associated neutrophils (TANs), suggesting major functional diversities. In this study, we focused on the mechanisms involved in neutrophil accumulation within the lung tumor mass. We first identified G-CSF as an inducer of the high-affinity glucose transporter Glut1 in neutrophils, increasing their survival ex vivo. In a genetically engineered mouse model of lung adenocarcinoma, we report that TANs have an increased Glut1 expression and glucose metabolism compared to normal neutrophils. To elucidate the impact of glucose uptake on TANs, we used an in vivo strategy based on two recombinases, Flp to initiate lung tumors, and Cre to delete Glut1 specifically in neutrophils. We demonstrate that the loss of Glut1 decreases the SiglecFhigh TAN subpopulation by accelerating neutrophil turnover in tumors through reduced survival and augmented recruitment. Accelerated TAN turnover led to a decreased tumor growth and synergized with radiotherapy. Altogether, our results demonstrate the importance of Glut1 for neutrophil turnover, which directly affects the pro- versus anti-tumor balance within the tumor. These results also suggest that metabolic vulnerabilities can be exploited to target tumor-supportive neutrophil populations.
