ABSTRACT

Dendritic cells (DCs) in lymphoid tissue arise from precursors that also produce monocytes and plasmacytoid DCs (pDCs). Where
DC and monocyte lineage commitment occurs and the nature of the DC precursor that migrates from the bone marrow to peripheral
lymphoid organs are unknown. We show that DC development progresses from the macrophage and DC precursor to common DC precursors
that give rise to pDCs and classical spleen DCs (cDCs), but not monocytes, and finally to committed precursors of cDCs (pre-cDCs).
Pre-cDCs enter lymph nodes through and migrate along high endothelial venules and later disperse and integrate into the DC
network. Further cDC development involves cell division, which is controlled in part by regulatory T cells and fms-like tyrosine
kinase receptor-3.

    • "+ ) can only generate cDCs [165]. Thus, it is possible that GM-CSF merely acts as a growth factor for certain DC precursors in vivo, whose increased turnover leads to the observed increase in DC numbers after GM-CSF treatment. "

    ABSTRACT: GM-CSF was originally identified as a colony stimulating factor (CSF) because of its ability to induce granulocyte and macrophage populations from precursor cells. Multiple studies have demonstrated that GM-CSF is also an immune-modulatory cytokine, capable of affecting not only the phenotype of myeloid lineage cells, but also T-cell activation through various myeloid intermediaries. This property has been implicated in the sustenance of several autoimmune diseases like arthritis and multiple sclerosis. In contrast, several studies using animal models have shown that GM-CSF is also capable of suppressing many autoimmune diseases such as Crohn's disease, Type-1 diabetes, Myasthenia gravis and experimental autoimmune thyroiditis. Knockout mouse studies have suggested that the role of GM-CSF in maintaining granulocyte and macrophage populations in the physiological steady state is largely redundant. Instead, its immune-modulatory role plays a significant role in the development or resolution of autoimmune diseases. This is mediated either through the differentiation of precursor cells into specialized non-steady state granulocytes, macrophages and dendritic cells, or through the modulation of the phenotype of mature myeloid cells. Thus, outside of myelopoiesis, GM-CSF has a profound role in regulating the immune response and maintaining immunological tolerance. Copyright © 2015 Elsevier Ltd. All rights reserved.

    • "In mice, splenic DCs are entirely replaced by circulating progenitors within 2 weeks (121). One would therefore expect the “adjuvant” effect of commensals on myeloid function to be transient and reversible. "

    ABSTRACT: Granulocytes, monocytes, macrophages, and dendritic cells (DCs) represent a subgroup of leukocytes, collectively called myeloid cells. During the embryonic development of mammalians, myelopoiesis occurs in a stepwise fashion that begins in the yolk sac and ends up in the bone marrow (BM). During this process, these early monocyte progenitors colonize various organs such as the brain, liver, skin, and lungs and differentiate into resident macrophages that will self-maintain throughout life. DCs are constantly replenished from BM precursors but can also arise from monocytes in inflammatory conditions. In this review, we summarize the different types of myeloid cells and discuss new insights into their early origin and development in mice and humans from fetal to adult life. We specifically focus on the function of monocytes, macrophages, and DCs at these different developmental stages and on the intrinsic and environmental influences that may drive these adaptations.

    • "The integrin CD11c is the hallmark surface marker for all DCs, although it is not exclusively expressed on DCs [59] [60]. The short-lived, phagocytic cDCs derive via pre-cDC progenitors [24] from CDPs [20]. In lymphoid organs, cDCs can be further subdivided into CD8α+ and CD4+ cDCs that are responsible for cross presentation of antigens to CD8α+ T cells or activation of CD4 + T cells, respectively [58].

    ABSTRACT: Cellular commitment to differentiation requires a tightly synchronized, spatial-temporal interaction of regulatory proteins with the basic DNA and chromatin. A complex network of mechanisms, involving induction of lineage instructive transcription factors, installation or removal of histone modifications and changes in the DNA methylation pattern locally orchestrate the three dimensional chromatin structure and determine cell fate. Maturation of myeloid lineages from haematopoietic stem cells has emerged as a powerful model to study those principles of chromatin mechanisms in cellular differentiation and lineage fate selection. This review summarizes recent knowledge and puts forward novel ideas on how dynamics in the epigenetic landscape of myeloid cells shape the development, immune-activation and leukaemic transformation outcome.
