We have identified a precursor that differentiates into granulocytes in vitro and vivo yet belongs to the monocytic lineage. termed these cells monocyte-like precursors of (MLPGs). Under steady state conditions, MLPGs were absent spleen barely detectable bone marrow (BM). In contrast, significantly expanded tumor-bearing mice differentiated polymorphonuclear myeloid-derived suppressor (PMN-MDSCs). Selective depletion had no effect on number naive but decreased population PMN-MDSCs by 50%....
By binding to Notch target genes, Ikaros shuts off the expression of these genes in T cells and prevents development cell acute lymphoblastic leukemia.
New strategies are needed to enhance the efficacy of anti–programmed cell death protein antibody (anti–PD-1 Ab) in cancer. Here, we report that inhibiting palmitoyl-protein thioesterase 1 (PPT1), a target chloroquine derivatives like hydroxychloroquine (HCQ), enhances antitumor anti–PD-1 Ab melanoma. The combination resulted tumor growth impairment and improved survival mouse models. Genetic suppression core autophagy genes, but not Ppt1, cancer cells reduced priming cytotoxic capacity...
The role of myeloid cells as regulators tumor progression that significantly impact the efficacy cancer immunotherapies makes them an attractive target for inhibition. Here we explore effect a novel, potent, and selective inhibitor serine/threonine protein kinase casein 2 (CK2) on modulating in microenvironment. Although inhibition CK2 caused only modest dendritic tumor-bearing mice, it substantially reduced amount polymorphonuclear myeloid-derived suppressor tumor-associated macrophages....
Multiple myeloma is characterized by clonal proliferation of plasma cells that accumulate preferentially in the bone marrow (BM). The tumor microenvironment one leading factors promote progression. Neutrophils and monocytes are a major part BM microenvironment, but mechanism their contribution to multiple progression remains unclear. Here, we describe novel which S100A8/S100A9 proteins produced neutrophils expansion megakaryocytes supporting alone was not sufficient drive megakaryopoiesis...
Natural killer (NK) cells are innate effector lymphocytes with strong antitumor effects against hematologic malignancies such as chronic lymphocytic leukemia (CLL). However, NK fail to control CLL progression on the long term. For effective lysis of their targets, use a specific cell-cell interface, known immunological synapse (IS), whose assembly and function critically rely dynamic cytoskeletal changes in cells. Here we explored role cell actin cytoskeleton during attack. We found that can...
Plasmacytoid and conventional dendritic cells (pDCs cDCs) arise from monocyte progenitors (MDPs) common (CDPs) through gene expression changes that remain partially understood. Here we show the Ikaros transcription factor is required for DC development at multiple stages. cooperates with Notch pathway activation to maintain homeostasis of MDPs CDPs. then antagonizes TGFβ function promote pDC differentiation Strikingly, Ikaros-deficient CDPs pDCs express a cDC-like transcriptional signature...
Abstract Alterations in the myeloipoiesis during cancer lead to production of myeloid-derived suppressor cells (MDSC). MDSC are comprised two subsets: monocytic (M-MDSC) and polymorphonuclear (PMN-MDSC). Both subsets contribute immunosuppressive tumor microenvironment. Therefore elimination could potentially improve clinical success immune therapy. Direct targeting progenitors is an attractive possibility. Our laboratory has recently discovered that M-MDSC from bone-marrow can give rise...
