Critical Role of Synovial Tissue-resident Macrophage Niche in Joint Homeostasis and Suppression of Chronic Inflammation

ABSTRACT: During synovial tissue homeostasis, both monocyte-derived F4/80int, and self-renewing F4/80hi tissue-resident, macrophage populations were identified. In contrast, in HUPO mice, decreased synovial tissue-resident macrophages preceded chronic arthritis, opened a niche permitting the influx of activated monocytes, which differentiated into F4/80hi macrophages.

Locally renewing resident synovial macrophages provide a protective barrier for the joint [scRNA-seq]

Project description:Macrophages (MΦs) are considered to contribute to chronic inflammatory diseases such as rheumatoid arthritis 1. However, both the exact origin and role of MΦs during inflammatory joint disease remain unclear. Here, we used multiple fate-mapping approaches in conjunction with 3D-light-sheet fluorescence microscopy and single cell RNA sequencing to perform a comprehensive spatiotemporal analysis of the composition, origin and differentiation of MΦ subsets within the healthy and inflamed joint and subsequently studied their roles during arthritis. This approach revealed dynamic membrane-like structures consisting of a distinct population of CX3CR1+ tissue-resident MΦs that formed an internal immunological barrier at the synovial lining and physically secluded the joint. Barrier-forming MΦs displayed features otherwise typical of epithelial cells, and maintained their numbers through a pool of locally proliferating CX3CR1- mononuclear cells embedded into the synovial tissue. Unlike recruited monocyte-derived MΦs, which actively contributed to joint inflammation, such epithelial-like CX3CR1+ lining MΦs restricted the inflammatory reaction by providing a tight junction-mediated shield for intra-articular structures. Our data thus reveal an unexpected functional diversification among synovial MΦs and have important implications for the general role of MΦs in health and disease

RNAseq of renal dendritic cells from adult Clec9a-Cre Rosa-YFP mice

Project description:We use bulk RNA sequencing of sorted cells to characterize the gene expression profiles of renal dendritic cell (DC) subsets, cDC1 and cDC2, as well as MHCII+CD64+ F4/80hi and MHCII+CD64+ CD11bhi cells. Splenic DCs and red pulp macrophages serve as reference populations for a macrophage-like or DC-like phenotype. By sorting YFP+/YFP- F4/80hi or YFP+/YFP- CD11bhi cells from Clec9a-Cre Rosa-YFP mice we aim to reveal transcriptional differences between YFP-labelled and unlabelled cells. We showed that F4/80hi cells resemble macrophages on a transcriptional level, despite their DC origin, and that renal CD11bhi cells are a transcriptionally unique subset. However, we were not able to reveal differences between YFP+ and YFP- populations.

CRIG identifies a novel population of highly phagocytic peritoneal macrophages associated with disease severity in patients with cirrhosis and ascites

Project description:Infections are an important cause of morbidity and mortality in patients with decompensated cirrhosis and ascites. Hypothesising that innate immune dysfunction contributes to susceptibility to infection, we assessed ascitic fluid macrophage phenotype and function. The expression of complement receptor of the immunoglobulin superfamily (CRIg) and CCR2 defined two phenotypically and functionally distinct peritoneal macrophage sub-populations. The proportion of CRIgHi macrophages differed between patients, and in the same patient over time, and a high proportion of CRIgHi macrophages was associated with reduced disease severity (Model for End Stage Liver Disease (MELD)) score. As compared to CRIgLow macrophages, CRIgHi macrophages were highly phagocytic and displayed enhanced antimicrobial effector activity. Transcriptional profiling by RNA Sequencing and comparison with human macrophage and murine peritoneal macrophage expression signatures highlighted similarities between CRIgHi cells, human macrophages and mouse F4/80Hi resident peritoneal macrophages, and between CRIgLow macrophages, human monocytes and mouse F4/80Low monocyte-derived peritoneal macrophages. These data suggest CRIgHi and CRIgLow macrophages may represent a tissue-resident population and a monocyte-derived population, respectively. In conclusion, ascites fluid macrophage subset distribution and phagocytic capacity is highly variable between patients with chronic liver disease. Regulating the numbers and/or functions of these macrophage populations could provide therapeutic opportunities in cirrhotic patients.

Transcriptome-based profiling reveals a macrophage pedigree and identifies Irf8 as pivotal for macrophage homeostasis and function

Project description:Recent studies have shown that tissue macrophages (MF) arise from embryonic progenitors of the yolk sac (YS) and fetal liver and colonize the tissues before birth. Further studies have proposed that developmentally distinct tissue MF can be identified based on the differential expression of F4/80 and CD11b, but whether a characteristic transcriptional profile exists is largely unknown. Here, we established an inducible fate mapping system that facilitated the identification of A2 progenitors of the YS as source of F4/80hi but not CD11bhi MF. Large-scale transcriptional profiling of MF precursors from the YS until adulthood allowed the description of a complex MF pedigree. We further identified a distinct molecular signature of F4/80hi and CD11bhi MF and found that Irf8 was vital for MF maturation and the innate immune response. Our data provide new cellular and molecular insights into the origin and developmental pathways of tissue MF. All samples are from mouse tissue at early developmental stages (E8, E9.5, E14) and from adulthood (6 weeks old). For the early developmental time points timed matings were performed. Macrophage populations were isolated from each tissue. RNA was isolated using Arcturus PicoPure isolation kit from yolk sac, brain, liver, kidney and skin samples after FACS sorting. Three replicates per cell population were included. Wildtype and Irf8 knockout samples were analyzed.
