Lining macrophages initiate articular inflammation

Project description:Lining macrophages initiate articular inflammation

Macrophages in the synovial lining niche initiate neutrophil recruitment and articular inflammation.

Project description:The first immune-activating changes within joint resident cells that lead to pathogenic leukocyte recruitment during articular inflammation remain largely unknown. In this study, we employ state-of-the-art confocal microscopy and image analysis in a systemic, whole-organ, and quantitative way to present evidence that synovial inflammation begins with the activation of lining macrophages. We show that lining, but not sublining macrophages phagocytose immune complexes containing the model antigen. Using the antigen-induced arthritis (AIA) model, we demonstrate that on recognition of antigen-antibody complexes, lining macrophages undergo significant activation, which is dependent on interferon regulatory factor 5 (IRF5), and produce chemokines, most notably CXCL1. Consequently, at the onset of inflammation, neutrophils are preferentially recruited in the vicinity of antigen-laden macrophages in the synovial lining niche. As inflammation progresses, neutrophils disperse across the whole synovium and form swarms in synovial sublining during resolution. Our study alters the paradigm of lining macrophages as immunosuppressive cells to important instigators of synovial inflammation.

RNASeq of bone lining niche cell components from myeloma-bearing mice treated daily with small molecule LDN193189 (LDN) or vehicle control

Project description:We compare gene expression in FACS-sorted bone lining cell components (stromal progenitors, osteoprogenitors, endothelial cells) from LDN193189 vs. vehicle-treated myeloma-bearing mice, and in myeloma cells flushed from the central marrow vs. myeloma cells digested from the bone-lining niche. The myeloma model used is the murine 5TGM1 cell line injected into immunocompetent KaLwRij mice. LDN193189 is a type 1 BMP receptor inhibitor.

The soluble CD83 protein prevents bone destruction by inhibiting the formation of osteoclasts and inducting resolution of inflammation

Project description:Here we show that soluble CD83 induces resolution of inflammation in the antigen-induced arthritis (AIA) model. Joint swelling as well as arthritis related expression levels of IL‐1β, IL‐6, RANKL, MMP9 and OC‐Stamp were strongly reduced, while Foxp3 was induced. In addition, we observed a significant inhibition of TRAP+ osteoclast formation, correlating with the reduced arthritic disease score. In contrast, cell specific deletion of CD83 in human and murine precursor cells resulted in an enhanced formation of mature osteoclasts. RNA-sequencing analyses, comparing sCD83- with mock treated cells, revealed a strong downregulation of osteoclastogenic factors, such as OC-STAMP, MMP9, NFATC1, Ctsk and Trap. Concomitantly, transcripts typical for pro-resolving macrophages, e.g. Mrc1/2, Marco, Klf4 and Mertk, were upregulated. Interestingly, also members of the metallothionein (MT) family, which have been associated with a reduced arthritic disease severity, were highly induced by sCD83 also in samples derived from RA patients. Finally, we elucidated the sCD83-induced signalling cascade, downstream to its binding to the Toll-like receptor 4/(TLR4/MD2) receptor complex, using CRISPR/Cas9-induced knockdowns of TLR4/MyD88/TRIF and MTs, revealing that sCD83 acts via the TRIF-signalling cascade. In conclusion, sCD83 represents a promising therapeutic approach to induce resolution of inflammation and to prevent bone erosion in autoimmune arthritis.

Pathologically distinct fibroblast subsets drive inflammation and tissue damage in arthritis

Project description:The identification of lymphocyte subsets with non-overlapping effector functions has been pivotal to the development of targeted therapies in immune mediated inflammatory diseases (IMIDs). Yet, despite their key role in disease, it remains unclear whether fibroblast subclasses with non-overlapping functions also exist and are responsible for the wide variety of tissue driven pathologies observed in IMIDs such as inflammation and damage . Here we identify and describe the biology of distinct subsets of fibroblasts responsible for mediating either inflammation or tissue damage in arthritis. We show that deletion of FAPa+ synovial cells suppressed both inflammation and bone erosions in murine models of resolving and persistent arthritis. Single cell transcriptional analysis identified two distinct fibroblast subsets: FAPa+ THY1+ immune effector fibroblasts located in the synovial sub-lining, and FAPa+ THY1- destructive fibroblasts restricted to the synovial lining. When adoptively transferred into the joint, FAPa+ THY1- fibroblasts selectively mediate bone and cartilage damage with little effect on inflammation whereas transfer of FAPa+ THY1+ fibroblasts resulted in a more severe and persistent inflammatory arthritis, with minimal effect on bone and cartilage. Our findings describing anatomically discrete, functionally distinct fibroblast subsets with non-overlapping functions have important implications for cell based therapies aimed at modulating inflammation and tissue damage.

Transcription profiling of human cord lining epithelial cells after phage integrase mediated integration

Project description:The two obstacles that impede a wider application of genetically modified cells expressing therapeutic transgenes for ex vivo gene therapy are the immune mediated rejection of the transplanted cells, combined with their potential to cause iatrogenic oncogenesis. In this study we describe a new cellular vehicle for this form of therapy,; termed the cord lining epithelial cell (CLEC). CLECs are derived from the human amnion and incorporate many of the immunoregulatory functions associated with the fetal/maternal interface. We show that CLECs can be safely transfected by phage ÏC31 integrase to accomplish site-specific integration of a therapeutic human transgene. We also show that transplanted CLECs are not oncogenic in vivo and can be maintained in immunocompetent mice where acute xeno-rejection rapidly destroys other human cell types. Finally, we demonstrate the utility of CLECs for ex vivo gene therapy by delivering human coagulation factor 8 to mice with Hemophilia A. Experiment Overall Design: The transcriptome datasets of human umbilical cord lining epithelial cells were compared before(CLEC) and 1 month after(CLEC-GFP) phage integrase mediated integration of EGFP cDNA into the genome. Transcriptome datasets were generated in singles and genes differentiallty expressed in cells before and after phage integrase treatment were analysed. Genes differentially expressed by at least 2 fold as compared to untreated CLEC were considered to be significantly dysregulated. List of genes with significant dysregulation were used for further analysis and to used to determine if genomic integration events had resulted in any potential geno-toxicity.
