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.

Myeloid-derived Suppressor Cells in Colorectal Cancer

Project description:The aim of the study is to evaluate whether the preoperative level of myeloid-derived suppressor cells is associated with postoperative complications classified by Clavien-Dindo categories. Levels of all MDSC, polymorphonuclear MDSC (PMNMDSC), monocytic MDSC (MMDSC), early-stage MDSC (EMDSC) and monocytic to polymorphonuclear MDSC ratio (M/PMN MDCS) were established and compared in patients with postoperative complications, severe postoperative complications (>= IIIA according to Clavien-Dindo) and severe septic complications.

The ETS transcription factor Elf5 drives lung metastasis in luminal breast cancer via recruitment of Gr-1+CD11b+ myeloid derived suppressor cells [acute]

Project description:Elf5 expression in mammary progenitor cells regulates a cell fate decision that establishes the alveolar cell lineage. In luminal breast cancer cells, increased Elf5 expression suppressed estrogen receptor and FoxA1 expression and was implicated in the acquisition of resistance to the cytostatic effects of antiestrogen therapy. We show that in the PyMT model of luminal breast cancer, increased Elf5 expression drives lung metastasis by recruiting myeloid-‐derived suppressor cells, and that this activity overcomes the epithelializing influence of Elf5. Breast cancer expression signatures identify a similar process in humans, and increased Elf5 immunohistochemical staining predicts poor prognosis in the luminal A subgroup. Thus Elf5 may promote escape from hormonal therapy and drive metastasis in luminal breast cancer.

Cell surface proteome profiling of cancer-associated fibroblast-induced myeloid-derived suppressor cells and related cell types

Project description:Cancer-associated fibroblasts (CAF) promote immune suppression in the tumor microenvironment by polarizing monocytes to myeloid-derived suppressor cells (MDSC) that potently suppress T-cell function. Using a patient-derived coculture system, we profiled the cell surface proteome of CAF-induced MDSC to identify potential mechanism through which T-cell function is impaired.

Proteomic profiling of extracellular vesicles from cancer-associated fibroblast-induced myeloid-derived suppressor cells and related cell types

Project description:Cancer-associated fibroblast (CAF) promote immune suppression in the tumor microenvironment by polarizing monocytes to myeloid-derived suppressor cells (MDSC) that potently suppress T-cell function. Using a patient-derived coculture system, we found that extracellular vesicles (EV) released by CAF-induced MDSC directly suppress T-cell proliferation. In this study, we profiled the protein cargo of the EVs isolated from CAF-MDSC and compared to related cell types.
