Intra-articular (IA) Injection of Empty Large Multilamellar Vesicles Liposomes Reduces Cartilage Degeneration in Rat Osteoarthritis Model
Background/Purpose: A suspension of empty large multilamellar vesicles (MLV) liposomes composed of dimyristoylphosphatidylcholine (DMPC) and dipalmitoylphosphatidylcholine (DPPC), is currently under clinical development for symptomatic knee…Abstract Number: 1471 • ACR Convergence 2021
Oral Administration of Berberine Limits Post-traumatic Osteoarthritis Development and Associated Pain via AMP-activated Protein Kinase (AMPK) in Mice
Background/Purpose: AMP-activated protein kinase (AMPK), a master regulator of energy balance and metabolism, is implicated to play an important role in cartilage homeostasis. Berberine is…Abstract Number: 1507 • ACR Convergence 2021
Role of CD4+ T Cells in the Pathogenesis of RA: Immunization with Citrullinated T Cell Epitopes Is Sufficient to Induce Immunological and Clinical Manifestations of Arthritis in DR4-Transgenic Mice
Background/Purpose: Although the etiology of rheumatoid arthritis (RA) remains unclear, existing research suggests a complex interplay of both genetic and environmental factors. Citrullinated proteins/peptides, and…Abstract Number: 1767 • ACR Convergence 2021
CXCL5 Dampens Inflammation in Murine Lupus by Orchestral Suppression of Effector Cell Proliferation and Leukocyte Extravasation
Background/Purpose: Systemic lupus erythematosus (SLE) is a potentially fatal autoimmune disease characterized by dysregulation of both innate and adaptive immunity. Current therapeutic options are limited,…Abstract Number: 1890 • ACR Convergence 2021
Cellular Origin and Functions of Osteoclasts in Inflammatory Arthritis
Background/Purpose: Inflammatory arthritis (IA) is an autoimmune disease targeting multiple joints and characterized by joint destruction caused by osteoclasts (OC), leading to physical disability. However,…Abstract Number: 0843 • ACR Convergence 2020
Rab4A Activation Predisposes to Hepatitis in Spontaneous and Pristane-Induced Mouse Models of Systemic Lupus Erythematosus
Background/Purpose: HRES-1/Rab4 or Rab4A, a GTPase responsible for mitochondrial oxidative stress1 and activation of the mechanistic target of rapamycin2, is overexpressed in T cells of…Abstract Number: 0846 • ACR Convergence 2020
MHC Class I Epitopes Derived from Autoantibody Variable Regions, Conjugated to Synthetic Oligodeoxynuleotides, Induce Cytotoxic T Cells That Deplete Autoreactive B Cells and Ameliorate Murine Lupus
Background/Purpose: B cell depletion or modulation is emerging as a major treatment modality for autoimmune diseases. However, the current treatments to accomplish this non-specifically target…Abstract Number: 0968 • ACR Convergence 2020
Combined Inhibition of Autophagy and Glutamine Metabolism Suppresses Cell Growth of RA Synoviocytes and Ameliorates Arthritis in SKG Mice
Background/Purpose: Immunometabolism is now recognaized to be crucial in the pathogenesis of rheumatoid arthritis (RA). We have recently shown that the expression of glutaminase 1…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: 0976 • ACR Convergence 2020
Kidney-infiltrating T Cells in Murine Lupus Nephritis Exhibit Transcriptional Heterogeneity and Oligoclonal Expansion
Background/Purpose: Lupus nephritis (LN) is a hallmark of SLE, affecting 50-60% of patients within 10 years of diagnosis. Current treatments for LN have suboptimal response…Abstract Number: 1221 • ACR Convergence 2020
Evaluation of Methotrexate Efficacy and Exploration of Metabolites Associated with Disease Activity in Collagen-induced Arthritis Mouse Model
Background/Purpose: Methotrexate (MTX) is cornerstone of therapy for rheumatoid arthritis. However, response to MTX is variable and unpredictable among patients. Therefore, there is a critical…
