ATAC-seq of Keratinocytes and Langerhans cells in normal and hyperproliferative epithelium

Project description:In an HPV-induced hyperplastic epithelium mouse model, hyperproliferative Keratinocytes (KCs) showed reduced Interleukin 34 (IL34) expression and chromatin accessibility, associating disturbing cell-cell interaction and immune response genes. Correspondingly, Langerhans cells (LCs) exhibited altered chromatin accessibility, including increased accessibility of IL34's receptor - the colony-stimulating factor 1 receptor (Csf1r) and reduced accessibility in antigen uptake and presentation genes.

Notch is active in Langerhans Cell Histiocytosis and confers pathognomonic features on dendritic cells.

Project description:Langerhans cell histiocytosis (LCH) is a disease characterized by the accumulation of eponymous CD1a+ Langerin+ Langerhans-cell (LC)-like dendritic cells (DC) of largely unknown origin. Here we have performed comparative transcriptome analysis of highly purified CD207+/CD1a+ Langerhans cell histiocytosis (LCH) cells derived from different locations and disease courses and three major human dendritic cell lineages: epidermal Langerhans cells, myeloid dendritic cells (mDC1) and plasmacytoid dendritic cells (pDC) in order to investigate the relationship between LCH cells and naturally occurring dendritic cells. Data obtained indicate that LCH cells form a distinct DC entity. Furthermore, we have identified transcripts that are uniquely expressed by LCH cells in comparison to LC, mDC1, and pDC, and induce LCH-specific features in human DC. Primary cells were isolated from peripheral blood (mDC1 and pDC), skin (epidermal Langerhans cells) and CD207+/CD1a+ Langerhans cell histiocytosis (LCH) cells derived from different locations. RNA was isolated from these cells ex vivo.

RNA-seq analysis of αPD-1 treatment outcomes in IL-34 expressing or not expressing CT26 cell line

Project description:Interleukin-34 (IL-34) is an alternative ligand to colony-stimulating factor-1 (CSF-1) for the CSF-1 receptor that acts as a key regulator of monocyte/macrophage lineage. In this study, we show that cancer cells-derived IL-34 mediates resistance to immune checkpoint blockade regardless of CSF-1 existence. In a therapeutic study of a programmed death-1 and cytotoxic T-lymphocyte-associated antigen-4 blocking monoclonal antibody, the expression of IL-34 in tumors was accompanied with limited benefits compared to IL-34 non-expressing tumors in various murine cancer models. Consistent with its immunosuppressive characteristics, the expression of IL-34 in tumors correlates with decreased frequencies of cellular (such as CD8+ and CD4+ T cells) and molecular (including various cytokines and chemokines) effectors at the tumor microenvironment. In addition, IL-34 blockade expands the M1-macrophage population. Then, a neutralizing antibody against IL-34 helped to reverse these effects and improved the therapeutic effects of the immune checkpoint blockade in combinatorial therapeutic models, including a patient-derived xenograft model of primary lung adenocarcinoma. Collectively, we revealed that tumor-derived IL-34 inhibits the efficacy of immune checkpoint blockade and proposed the utility of IL-34 blockade as a new strategy for cancer therapy.

Monocytes Give Rise To Langerhans Cells That Preferentially Migrate To Lymph Nodes At Steady State

Project description:It is still debated whether the homeostatic function of tissue macrophages is dependent on their origin, and evidence suggests this may depend on the tissue of macrophage residence. Here, we answered this question for Langerhans cells (LCs), an embryonic-derived mononuclear phagocyte that has features of both tissue macrophages and dendritic cells. Using time-course analyses, bone marrow chimeras and fate tracing models, we found that the complete elimination of embryonic-derived LCs at steady state results in their repopulation from circulating monocytes. However, monocyte-derived LCs inefficiently replenished the epidermal niche. Instead, these cells preferentially migrated to skin draining lymph nodes. Mechanistically, we show that the superior migratory capability of monocyte-derived LCs is associated with higher expression of CD207/Langerin, a C-type lectin involved in the capture of skin microbes. Our data shows that ontogeny plays a role in the migratory behavior of epidermal LCs.
