Resumen

Abstract Abstract 2794 Poster Board II-770 Myeloid-derived suppressor cells (MDSCs) are a heterogeneous mix of myeloid cells in different maturation stages generated in the bone marrow. The role of MDSCs in cancer is to suppress T-cell responses, thereby likely regulating tumor progression. In mice, MDSCs are identified by the expression of the surface markers CD11b and Gr-1. Recently, Ly6G+ granulocytic (PMN-MDSC) and Ly6G− monocytic (MO-MDSC) subsets could be distinguished (Movahedi et al. Blood 2008, 111:4233-44). In multiple myeloma patients, the immune function is impaired and this is cau

Resumen

Abstract The immunosuppressive tumor microenvironment presents a significant challenge to developing effective T cell-based cancer immunotherapies. Myeloid-derived suppressor cells (MDSCs), a heterogeneous group of cells, are a major contributor to the suppressive tumor microenvironment. MDSCs are immature myeloid cells that develop in response to chronic inflammation generated by an infection or a tumor. Currently, strategies to block MDSC-mediated suppression generate modest anti-tumor responses. This is in part due to lack of specific markers to target MDSCs and inability to simultaneously

Resumen

Abstract Myeloid-derived suppressor cells (MDSC) are a heterogeneous population of cells that accumulate in individuals with cancer and inflammation and play a pivotal role in tumor immunity by suppressing T-cell activation and secreting proinflammatory molecules. The suppressive capacity of MDSC is mediated by immune suppressive factors such as arginase and reactive oxygen species (ROS). Nuclear protein, High Mobility Group Box1 (HMGB1), is present in nearly all cells and is released from myeloid cells as a danger response to sepsis, infection, or arthritis. Its release promotes inflammatory

Resumen

BackgroundImmune suppression is common in neoplasia and a major driver is tumor-induced myeloid dysfunction. Yet, overcoming such myeloid cell defects remains an untapped strategy to reverse suppression and improve host defense. Exposure of bone marrow progenitors to heightened levels of myeloid growth factors in cancer or following certain systemic treatments promote abnormal myelopoiesis characterized by the production of myeloid-derived suppressor cells (MDSCs) and a deficiency in antigen-presenting cell function.

Abstract INTRODUCTION Infiltrating immune-suppressive myeloid cells represent a tumor supportive population that contributes to immune checkpoint inhibitor resistance and poor survival in Glioblastoma (GBM) patients. We have previously characterized monocytic-myeloid derived suppressor cells (M-MDSCs) based on their dual expression of chemokine receptors CCR2 and CX3CR1(CCR2+/CX3CR1+). Genetic and pharmacologic targeting of CCR2, in combination with PD-1 blockade, reduced the percentage of M-MDSCs in the glioma-microenvironment and slowed the progression of KR158 and 005GSC murine gliomas.

Resumen

Activated normal density granulocytes (NDGs) can suppress T-cell responses in a similar way as myeloid-derived suppressor cells (MDSCs). In this study, we tested the hypothesis that NDGs from blood and bone marrow of multiple myeloma (MM) patients have the ability to suppress T-cells, as MDSC. MM is an incurable plasma cell malignancy of the bone marrow. Like most malignancies, myeloma cells alter its microenvironment to promote tumor growth, including inhibition of the immune system. We found that MM NDG from the bone marrow suppressed proliferation of T-cells, in contrast to healthy donors.

Resumen

Tumor–stroma interactions contribute to tumorigenesis. Tumor cells can educate the stroma at primary and distant sites to facilitate the recruitment of heterogeneous populations of immature myeloid cells, known as myeloid-derived suppressor cells (MDSCs). MDSCs suppress T cell responses and promote tumor proliferation. One outstanding question is how the local and distant stroma modulate MDSCs during tumor progression. Down-regulation of β-catenin is critical for MDSC accumulation and immune suppressive functions in mice and humans. Here, we demonstrate that stroma-derived Dickkopf-1 (Dkk1) ta

Abstract Radiation therapy (RT) can both stimulate antitumor immunity and induce immunosuppressive responses, complicating its therapeutic efficacy. Data indicate that certain patient subsets—such as those undergoing combination treatment with radiation and immune-oncology drugs and/or targeted therapies may benefit from strategies that target immunosuppression or metastasis-promoting factors. One of the key challenges is the heterogeneous and context-dependent nature of myeloid suppressive states in the tumor microenvironment, which often leads to resistance to RT and immunotherapy.

Since DC and MDSC arise from common myeloid progenitors, and Flt3L-driven DC expansion is STAT3-dependent, we sought to precisely define the role of STAT3 in MDSC downstream of Flt3L signaling. We bred myeloid cell-specific STAT3-deficient mice (LysMCre x STAT3loxP) and administered Flt3L (10 μg/d ip, 10d). Splenic DC (CD1

While inflammation is linked to MDSC function, it is unknown if MDSC isolated from the inflammatory site possess equal regulatory function as those in distal sites such as the spleen.

Abstract Balance between immune activation and immune suppression is important for immune homeostasis. Toll-like receptors (TLRs) play key roles in the innate immune system, initiating inflammatory responses against pathogen infections and internal danger signals. Different TLRs recognize different kinds of ligands, but not all the TLRs do have same effect: some TLRs are immune stimulatory, while the others are immune suppressive. For instance, TLR5 ligand has been known to be immune suppressive, while TLR7 ligand has been used for immune activation. To understand how these TLR ligands lead to

Resumen

Oncolytic reovirus preferentially targets and kills cancer cells via the process of oncolysis, and additionally drives clinically favorable antitumor T cell responses that form protective immunological memory against cancer relapse. This two-prong attack by reovirus on cancers constitutes the foundation of its use as an anticancer oncolytic agent. Unfortunately, the efficacy of these reovirus-driven antitumor effects is influenced by the highly suppressive tumor microenvironment (TME). In particular, the myeloid cell populations (e.g., myeloid-derived suppressive cells and tumor-associated mac

INTRODUCTION: Mutations in isocitrate dehydrogenase (IDH) are a significant prognostic and biological factor leading to slower growth and T cell suppression within diffuse gliomas. However, the effect of IDH and its downstream metabolites specifically on intratumoral myeloid cells remains underexplored. METHODS: Utilizing patient tumor samples, we performed RNA-sequencing and quantitative immunofluorescence on IDH-wildtype glioblastoma and IDH-mutant grade 4 astrocytoma cases. We then engineered the murine GL261 glioma cell line to harbor mutant IDH, comparing transcriptomic and cell-level cha

Resumen

Abstract Myeloid-derived suppressor cells (MDSC) are a heterogeneous population of cells that accumulate in individuals with cancer and inflammation and play a pivotal role in tumor immunity by suppressing T-cell activation and secreting proinflammatory molecules. MDSC potency is mediated by immune suppressive factors such as inducible NO synthase (iNOs), arginase, and reactive oxygen species (ROS). MDSC also impair tumor immunity through crosstalk with macrophages in which IL-10 production increases while IL-12 production decreases, causing a shift in innate and adaptive immunity towards a ty

Resumen

Abstract The immune-editing effect of myeloid leukemia has recently been reported in several studies. We previously demonstrated that the K562 leukemia-derived cell line suppresses T cell proliferation, which suggests that myeloid leukemia may function in a similar way to myeloid derived suppressor cells (MDSC). While the mechanism of suppression in leukemia is not fully understood, recent murine and human studies suggest that the STAT3 and arginase pathways play a key role in the immunosuppressive function of MDSC. We hypothesized that myeloid leukemia utilizes the MDSC STAT3 and arginase pat

Resumen

Neonates are at an increased risk of an infectious disease. This is consistent with an increased abundance of myeloid-derived suppressor cells (MDSCs) compared with older children and adults. Using a murine model of neonatal bacterial sepsis, we demonstrate that MDSCs modulate their activity during an infection to enhance immune suppressive functions. A gene expression analysis shows that MDSCs increased NOS2, Arg-1 and IL-27p28 expression in vitro and in vivo in response to Escherichia coli O1:K1:H7 and this is regulated at the level of the gene expression.

Resumen

Abstract Persistent viral infections in mice (e.g. lymphocytic choriomeningitis virus, LCMV) and humans (e.g. HIV, hepatitis C virus) are characterized by chronic inflammation. This sustained inflammatory milieu promotes T cell exhaustion, which limits harmful tissue damage but prevents effective viral control. We found that natural killer (NK) cells aid in the establishment of this tolerogenic state through cytolytic elimination of antiviral T cells. In parallel, others shown that chronic infection encourages expansion of immunoregulatory IL-10-expressing myeloid cells and bona fide myeloid-d

Abstract We recently demonstrated that human BM cells can be treated in vitro with defined growth factors to induce the rapid generation of myeloid-derived suppressor cells (MDSCs), hereafter defined as BM-MDSCs. Indeed, combination of G-CSF + GM-CSF led to the development of a heterogeneous mixture of immature myeloid cells ranging from myeloblasts to band cells that were able to suppress alloantigen- and mitogen-stimulated T lymphocytes. Here, we further investigate the mechanism of suppression and define the cell subset that is fully responsible for BM-MDSC–mediated immune suppression. This

The presence of MDSCs also results in elevation of IL-17A production and upregulation of the orphan nuclear receptor RORA and RORC in T cells.

The role of BTK in B cell receptor signaling is well defined and is known to play a key role in the proliferation and survival of malignant B cells. Moreover, BTK has been found to be expressed in cells of the myeloid lineage. BTK has been shown to contribute to a variety of cellular pathways in myeloid cells including signaling in the NLRP3 inflammasome, receptor activation of nuclear factor-κβ and inflammation, chemokine receptor activation affecting migration, and phagocytosis.

Abstract Myeloid cells are increasingly recognized for their potent regulatory abilities. However, factors influencing regulatory myeloid cell (regMC) differentiation remain poorly understood. Retinoic acid (RA) is a steroid hormone important in regulating mucosal (gut) immunity. RA also promotes myeloid differentiation. We hypothesize that RA during differentiation will promote regMC formation (both regulatory DCs and macrophages). Using in vitro differentiation of myeloid cells with GM-CSF with or without RA, we found that day 6-7 RA BM-MCs were more mature/activated (i.e. increased expressi
