Single Cell Transcriptomic Analysis of Popliteal Lymph Nodes from TNF-Tg Mice with Early and Advanced Inflammatory-Erosive Arthritis

ABSTRACT: Immune cell dynamics in lymph nodes downstream of inflamed joints are associated with inflammatory-erosive arthritis in both tumor necrosis factor transgenic (TNF-Tg) mice and rheumatoid arthritis (RA) patients. In TNF-Tg mice, "Early" stages of arthritis are related to dramatic PLN "Expansion" with increases in joint-draining popliteal lymph node (PLN) volume and fluid flow, while CD21-high / CD23+ B-cells in inflamed nodes (Bin cells) accumulate in the PLN follicles. Onset of "Advanced" inflammatory-erosive arthritis is related to a PLN "Collapse" where fluid flow is reduced as Bin cells translocate from the PLN follicles into the sinuses and are thought to mechanically inhibit lymphatic drainage. Through single-cell RNA-sequencing, we aimed to evaluate changes in PLN immune cell populations during Early and Advanced arthritis to determine mechanisms mediating the Bin cell translocation and the relationship with arthritic progession in the afferent joints.

Spatial Transcriptomics of Joint-Draining Popliteal Lymph Nodes from Wild-type and TNF-Tg Mice with Early and Advanced Inflammatory-Erosive Arthritis

Project description:Lymphatic dysfunction is an integral aspect of rheumatoid arthritis (RA) pathogenesis. During "Early" arthritis in tumor necrosis factor transgenic (TNF-Tg) mice, the joint-draining popliteal lymph nodes (PLNs) dramatically expand in volume. After a prolonged expansion phase, at ~8-months-old the PLNs stochastically collapse with reduced bone volume and associated onset of "Advanced" inflammatory-erosive arthritis in affected joints. Through this pathologic process, B-cells are known to translocate into the PLN sinuses. Bulk tissue approaches (i.e. bulk genomics, flow cytometry, and ex vivo cell cultures) have been insufficient to specifically evaluate the transcriptional changes of B-cells within the sinuses of TNF-Tg PLNs. Thus, we utilized spatial transcriptomics technology to evaluate transcriptional changes in sinus B-cells and the functional genomic relationships with arthritic severity.

Proteome of neutrophils upon migration towards inflamed synovial fluid

Project description:Analysis of neutrophil proteomic alterations induced by migration towards inflamed joints in juvenile idiopathic arthritis (JIA). In this experiment neutrophil proteomes were investigated after migration towards JIA synovial fluid in an in vitro model of a synovial membrane, compared to neutrophils incubated in synovial fluid without migration. The migration model consisted of transwell inserts with human knee synoviocytes on the undersides and HMEC endothelial cells on the insides, placed in wells containing medium with 10 % JIA synovial fluid.

CTLA-4-Ig internalizes CD80 in fibroblast-like synoviocytes from chronic inflammatory arthritis mouse modelinflammatory arthritis mouse model

Project description:In this study, the therapeutic effect of CTLA-4-Ig in a mouse model of rheumtaoid arthritis, in which CD80 is expressed in chondrocytes and the synovial cells of joints. The therapeutic effect of CTLA-4-Ig appears to extend beyond the lymph nodes into the inflamed synovial compartment through the synergistic inactivation of T cells by the CD80 and PD-L1 axes.

Single-cell transcriptomes and T cell receptor sequences of memory T lymphocytes from the peripheral blood and the synovial fluid of patients with juvenile idiopathic arthritis.

Project description:Antigen-experienced (or memory) T lymphocytes were isolated from the synovial fluid of inflamed joints and the peripheral blood of patients with juvenile idiopathic arthritis (JIA). After flow-sort of CD4+CD45RO+CD25- (Tcon), CD4+CD45RO+CD127loCD25+ (Treg) and CD8+CD45RO+ T cells, single-cell RNA-sequencing was conducted to perform paired analyses of gene transcription and T cell receptor (TCR) repertoires in the same cells. The study aimed to identify T memory cells that were stimulated by antigens in inflamed joints of JIA patients and which perpetuate chronic inflammation by expression pro-inflammatory genes. In addition, the study aimed at understanding the clonal relationships of T cells differentiating at chronically inflamed sites, as well as to identify blood-circulating T cell clones that shared gene expression and antigen-specificity with T cells in inflamed joints in order to improve patient stratification and diagnostics of patients with chronic inflammatory diseases in the future.

Dissecting the molecular control of immune cell accumulation in the inflamed joint

Project description:Mechanisms governing entry and exit of immune cells into, and out of, inflamed joints, remain poorly understood. We sought herein to identify the key molecular pathways regulating such migration. Using murine models of inflammation in conjunction with mice expressing a photoconvertible fluorescent protein we characterized the migration of cells from joints to draining lymph nodes (LN) and performed RNA-seq analysis on isolated cells, identifying genes associated with migration and retention. We further refined the gene list to those specific for joint inflammation. RNA-seq data revealed pathways and genes previously highlighted as characteristic of Rheumatoid arthritis (RA) in patient studies, validating the methodology. Focusing on pathways associated with cell migration, adhesion and movement, we identified genes involved in the retention of immune cells in the inflamed joint, namely JAM-A, and identified a role for such molecules in T cell differentiation in vivo. Thus, using a combination of novel cell tracking approaches and murine models of inflammatory arthritis we have identified genes, pathways and anatomically specific tissue signatures regulating cell migration in a variety of inflamed sites. This unique skin and joint specific dataset will be an invaluable resource for the identification of novel therapeutic targets for arthritis and other inflammatory disorders.

Single Cell Transcriptomic Analysis of Popliteal Lymphatic Vessels and Peripheral Veins with Smooth Muscle Cell Enrichment in TNF-Tg vs WT Mice

Project description:Lymphatic dysfunction exists in tumor necrosis factor transgenic (TNF-Tg) mice and rheumatoid arthritis (RA) patients. While joint-draining TNF-Tg popliteal lymphatic vessels (PLVs) have deficits in contractility during end-stage arthritis, the nature of lymphatic muscle cells (LMCs) and their TNF altered transcriptome remain unknown. Thus, we performed single-cell RNA-sequencing (scRNAseq) on TNF-Tg vs wild-type peripheral vasculature. We utilized strategic enrichment for smooth muscle cells using a Cspg4-Cre;tdTomato reporter model, and through post-hoc analysis we validated the ability to enrich for these tdTomato+ populations based on scatter alone. As such, we evaluated changes in LMC populations vs vascular smooth muscle cells (VSMCs), and dynamic changes in peri-vascular immune cell populations during chronic inflammatory-erosive arthritis.

RNA-seq of mouse fibroblast-like synoviocytes (FLS) isolated from mice with collagen-induced arthritis (CIA) and naive littermates

Project description:Fibroblast-like synoviocytes (FLS) were isolated from the inflamed joints of mice with collagen-induced arthritis (CIA) or the joints of naive littermates to characterise gene expression changes in response to chronic inflammation. Cells were isolated at two times of day (zeitgeber time, ZT4 and ZT16) to characterise diurnal variation in inflammatory symptoms and responses. FLS cells were isolated from joint digests based on Podoplanin expression prior to RNA extraction and library preparation for sequencing.
