Profiling of murine resident adipose tissue and aortic macrophages according to their expression status of LYVE-1

ABSTRACT: Beside their role in conventional immune regulation, macrophages are now recognised as essential regulator of local tissue homeostasis depending on the tissue in which they reside. Using phenotyping, we found that LYVE-1+ macrophages are the major resident macrophage population in murine aorta and adipose tissues under steady state. Furthermore, imaging analysis revealed the exclusive association of adipose tissue LYVE-1+ macrophages with smooth muscle positive large blood vessels. Hence, we hypothesize that LYVE-1+ macrophages sustain large vessel functional homeostasis. The present experiment aims to better characterize resident LYVE-1+ vs LYVE-1- macrophages in aorta and adipose tissues.

Resident macrophages promote homeostasis of hyaluronan-associated extracellular matrix in the mammary gland stroma

Project description:Tissue resident macrophages in the mammary gland are found in close association with epithelial structures and within the adipose stroma, and are important for mammary gland development and tissue homeostasis. While epithelial-associated macrophages have been linked to ductal development, the contributions of stromal macrophages to mammary gland homeostasis remain unknown. Using transcriptional profiling, we identify a distinct resident stromal macrophage subpopulation that is characterized by expression of Lyve-1, a receptor for the extracellular matrix component hyaluronan. This subpopulation is enriched in genes associated with extracellular matrix remodeling and is found to be specifically associated with hyaluronan-rich regions within the mammary stroma. Furthermore, macrophage depletion leads to increased accumulation of hyaluronan-associated extracellular matrix in the mammary stroma. These results demonstrate the presence of a distinct subpopulation of macrophages and provide insights into the functional contributions of these macrophages to stromal homeostasis in the mammary gland.

Transcription profile of adipose-resident macrophages and mesenchymal stem cells.

Project description:It is commonly-recognized that hematopoietic cells residing in adipose tissue (AT) exhibit a broad range of physiological functions for maintenance of homeostasis and remodeling and repair of tissues aside from the involvement in inflammation. We evaluated the cell composition of hematopoietic cells in human non-obese AT and analyzed AT-resident macrophages in detail. Liposuction aspirates were obtained from healthy donors undergoing liposuction of the abdomen and thighs. CD34-positive AT resident macrophages (ATMs), CD34-negative ATMs and adipose stromal cells were sorted from aspirated AT by a multiparameter fluorescent-activated cell sorter. Circulating monocytes were also sorted from peripheral blood.These 4 condition were analysed transcription profile.

Lyve-1 deficiency plasma proteomics

Project description:Hyaluronan receptor LYVE-1 is expressed by liver sinusoidal endothelial cells (LSEC), lymphatic endothelial cells and specialized macrophages. Besides binding hyaluronan, LYVE-1 mediates adhesion of leukocytes and cancer cells to endothelial cells. Here, we analyzed the impact of LYVE-1 on physiological liver functions and metastasis. Mice with deficiency of Lyve-1 (Lyve-1 KO) were analyzed using histology, immunofluorescence, RNA sequencing, plasma proteomics and flow cytometry. Liver metastasis was studied by intrasplenic/intravenous injection of melanoma (B16F10luc2, WT31) or colorectal carcinoma (MC38) cell lines. Results: Hepatic architecture, liver size, endothelial differentiation and angiocrine functions were unaltered in Lyve-1 KO mice. Hyaluronan plasma levels were significantly increased in Lyve-1-KO mice; besides, plasma proteomics revealed increased carbonic anhydrase-2 and decreased FXIIIA, potential modulators of metastatis. Furthermore, gene expression analysis of LSEC indicated regulation of immunological pathways. Therefore, liver metastasis of a highly and of a weekly immunogenic tumor, i.e. melanoma and colorectal carcinoma (CRC), was analyzed in Lyve-1 KO mice. Hepatic metastasis of B16F10 luc2 and WT31 melanoma cells, but not MC38 CRC cells, was significantly reduced in Lyve-1 KO mice. While short-term adhesion assays with B16F10 luc2 cells in vivo did not show differences between Lyve-1 KO and wild-type mice, increased numbers of resident hepatic CD4+, CD8+ and regulatory T cells were detected in Lyve-1 KO livers. In addition, iron deposition was detected in F4/80+ liver macrophages known to exert pro-inflammatory effects. Conclusions: LYVE-1 deficiency controlled hepatic metastasis in a tumor cell-specific manner reducing hepatic metastasis of melanoma, but not CRC. Anti-tumorigenic effects are likely due to enhancement of the resident hepatic immune microenvironment.

White adipose tissue resident macrophages are required for adipogenesis and energy storage.

Project description:White adipose tissue (WAT) stores energy in the form of lipids. WAT macrophages cause adipose tissue inflammation and insulin resistance when intake exceeds expenditures, but their contribution to homeostasis remain poorly understood. Here, we show that two populations, ã and ä, of TNF-producing bone marrow-derived monocytic cells are transiently recruited to damaged adipocytes and mediate insulin resistance. In contrast, we identify α/β yolk-sac derived resident macrophages that produce adipogenic growth factors, and form a niche required for adipogenesis as white adipocytes do not differentiate in their absence. Production of adipogenic growth factors by α/β macrophages increases with lipid storage, but they do not contribute to inflammation. Thus the molecular identities and functions of resident macrophages and BM-derived cells are specified by their lineage rather than diet variation. These results identify an essential function of WAT resident macrophages in adipogenesis and energy homeostasis, separate from inflammation mediated by the recruitment of inflammatory leukocytes.

microRNA transcriptome data from wild type and Gata6-deficient tissue resident peritoneal macrophages

Project description:microRNA transcriptome data from wild type and Gata6-deficient tissue resident peritoneal macrophages. Tissue resident macrophages are notoriously heterogeneous, exhibiting discrete phenotypes as a consequence of tissue- and micro-anatomical niche-specific functions, but the molecular basis for this is not understood. Gata6 itself has been shown to be a target of multiple miR. However, microRNA transcriptome and its dependence on tissue-specific macrophage programming, such as effected by GATA6, has not been explored. We used microRNA sequencing to determine the patterns of microRNA expression in peritoneal resident macrophages at homeostasis in the absence of GATA-6 against wild type.

Tissue-resident macrophage enhancer landscapes are shaped by the local microenvironment [RNA-seq]

Project description:Macrophages are hematopoietic cells critical for innate immune defense, but also control organ homeostasis in a tissue-specific manner. Tissue-resident macrophages, therefore, provide a well-defined model to study the impact of ontogeny and microenvironment on chromatin state. Here, we profile the dynamics of four histone modifications across seven tissue-resident macrophage populations, as well as monocytes and neutrophils. We identify 12,743 macrophage-specific enhancers and establish that tissue-resident macrophages have distinct enhancer landscapes. Our work suggests that a combination of tissue and lineage-specific transcription factors form the regulatory networks controlling chromatin specification in tissue-resident macrophages. The environment has the capacity to alter the chromatin landscape of macrophages derived from transplanted adult bone marrow in vivo and even differentiated macrophages are reprogrammed when transferred into a new tissue. Altogether, these data provide a comprehensive view of macrophage regulation and highlight the importance of microenvironment along with pioneer factors in orchestrating macrophage identity and plasticity. 7 tissue-resident macrophage populations were isolated, as well as monocytes and neutrophils, and transcriptome analysis was performed. Experiment was done in duplicates.

Wildtype and NRP1 knockout macrophages

Project description:Obesity gives rise to metabolic complications by mechanisms that are poorly understood. While chronic inflammatory signaling in adipose tissue is typically associated with metabolic deficiencies linked to excessive weight gain, we identified a subset of NRP1-expressing myeloid cells that accumulate in adipose tissue and protect against obesity and metabolic syndrome. Ablation of NRP1 in macrophages compromised lipid uptake in these cells, which reduced substrates for fatty acid β-oxidation and shifted energy metabolism of these macrophages towards a more inflammatory glycolytic metabolism. Conditional deletion of NRP1 in LysM Cre-expressing cells lead to inadequate adipose vascularization, accelerated weight gain and reduced insulin sensitivity even independent of weight gain. Transfer of NRP1+ hematopoietic cells improved glucose homeostasis, resulting in the reversal of a prediabetic phenotype. Our findings suggest a pivotal role for adipose tissue resident NRP1+-expressing macrophages in driving healthy weight gain and maintaining glucose tolerance.

Heterogeneous Origins and Functions of Mouse Skeletal Muscle Resident Macrophages

Project description:Tissue resident macrophages can arise from either embryonic or adult hematopoiesis and play important roles in a wide range of biological processes, such as tissue remodeling during organogenesis, tissue homeostasis in the steady state, tissue repair following injury, and immune response to pathogens. Although the origins and tissue-specific functions of resident macrophages have been extensively studied in many other tissues, they are not well characterized in skeletal muscle. In the present study, we have characterized for the first time the ontogeny of skeletal muscle resident macrophages, showing evidence that they arise from both embryonic hematopoietic progenitors, including yolk sac primitive macrophages and fetal liver monocytes, and adult bone marrow hematopoietic stem cells. Single cell-based transcriptome analysis revealed that skeletal muscle resident macrophages were highly distinctive from resident macrophages in other tissues, expressing a specific set of transcription factors and containing functionally diverse subsets correlating to their origins. They appear more active in maintaining tissue homeostasis and promoting muscle growth and regeneration.
