Arthritogenic T Cells Harbor a Transcriptional Program of T Cell Activation and a Repertoire Pruned by Endogenous Superantigen
Background/Purpose: It is widely accepted that activation of specific CD4 T cells through their TCRs by self-antigen (Ag) is necessary for rheumatoid arthritis (RA) onset.…Abstract Number: 1891 • ACR Convergence 2021
Variable Effects of Testosterone on Male versus Female Derived Macrophages in Inflammatory Arthritis
Background/Purpose: Rheumatoid arthritis (RA) is a chronic inflammatory joint disease that is female predominant. The TNF-transgenic (TNF-Tg) mouse model of RA also develops a sexually…Abstract Number: 0774 • ACR Convergence 2020
Nr4a1-high Arthritogenic T Cells from SKG Mice Are Associated with Markers of Recent and Chronic Antigen-stimulation and an Altered T Cell Receptor Repertoire
Background/Purpose: T cells can either be activated through their T cell receptor (TCR) in an antigen-specific manner, or in response to cytokines. Identification of antigen-reactive…Abstract Number: 0778 • ACR Convergence 2020
Bacterial Families Lachnospiraceae/Ruminococcaceae Are Immunologically Targeted in Individuals At-risk for RA and a Specific Strain Is Arthritogenic in Monocultured Gnotobiotic Mice
Background/Purpose: Circulating autoantibodies, including anti-CCP and RF, develop years before physical manifestations of rheumatoid arthritis (RA), with several lines of evidence suggesting that these autoantibodies…Abstract Number: 0781 • ACR Convergence 2020
Phenotypic and Functional Characterisation of Synovial Fluid-derived Fibroblast-like Synoviocytes in Rheumatoid Arthritis
Background/Purpose: Fibroblast-like synoviocytes (FLS) are central cellular components in persistent inflammatory joint diseases such as rheumatoid arthritis (RA). Pathological subsets of FLS have been identified…Abstract Number: 0966 • ACR Convergence 2020
Decoupling Inflammation and Bone Loss in Rheumatoid Arthritis via Schnurri-3
Background/Purpose: Rheumatoid arthritis (RA) is a chronic inflammatory disease that leads to local and systemic bone loss. TNF is a key mediator of bone loss,…Abstract Number: 0969 • ACR Convergence 2020
Investigating Murine Joint-Draining Lymphatics: Lineage Tracing and Single Cell RNA Sequencing Reveal Evidence That Popliteal Lymphatic Muscle Cells and Their Progenitors Represent Distinct Cell Types Divergent from Striated and Vascular Muscle Cells
Background/Purpose: Previous studies demonstrated that tumor necrosis factor transgenic (TNF-Tg) mice with inflammatory arthritis have damaged lymphatic muscle cells (LMCs) and eventual loss of popliteal…Abstract Number: 1407 • ACR Convergence 2020
Resolvin D5 Modulates Th17/Treg Cell Differentiation and Suppresses Osteoclastogenesis
Background/Purpose: Over the last two decades, it has become increasingly clear that resolution of acute inflammation is not a passive process, but requires active modulation.…
