Effect of Anti-inflammatory Drugs on Intestinal Epithelial Damage and Bacterial Translocation in the Adjuvant-induced Arthritis Model
Background/Purpose: The intestine is no longer considered as an organ targeted by spondyloarthritis (SpA) but also an actor of the disease alongside environmental and immunological…Abstract Number: 0459 • ACR Convergence 2021
CCN1: An Angiogenic Actor Implicated in the Structural Damages of Rheumatoid Arthritis
Background/Purpose: We have previously shown that decreased expression of the deacetylase sirtuin-1 (SIRT1) contributes to the proliferative, activated and proangiogenic profile of endothelial cells (EC)…Abstract Number: 0534 • ACR Convergence 2021
Lymphatic Dysfunction in Murine Lupus Photosensitivity
Background/Purpose: The lymphatic system is composed of vessels which carry fluid, soluble molecules, and cells from peripheral tissue to draining lymph nodes. Photosensitivity, an exaggerated…Abstract Number: 0536 • ACR Convergence 2021
The EIF4 Translational Inhibitor Pateamine a Improves Immunological and Neurological Functions in BXSB.yaa Lupus Mice
Background/Purpose: Systemic Lupus Erythematosus (SLE) is an autoimmune disease characterized by loss of tolerance and activation of the immune response. Clinical manifestations are heterogeneous and…Abstract Number: 1017 • ACR Convergence 2021
Osteoclast-Specific Transmembrane Protein (OC-STAMP) Regulates Osteoclastogenesis and Inhibits Inflammation in an Acute Arthritis Model
Background/Purpose: Dendritic Cell (DC)-Specific Transmembrane Protein (STAMP) expressed by osteoclast precursors is required for cell-cell fusion in the formation of the osteoclast (OC) polykaryon. Genetic…Abstract Number: 1019 • ACR Convergence 2021
Cigarette Smoking Induces Post-translational Protein Modifications in Both in Vitro and in Vivo Models of Rheumatoid Arthritis-associated Interstitial Lung Disease
Background/Purpose: Cigarette smoking has been epidemiologically linked to the development of ACPA+ rheumatoid arthritis (RA) and, by extension, RA-associated interstitial lung disease (RA-ILD). Providing strong…Abstract Number: 1020 • ACR Convergence 2021
Enhancing Endothelial Cell Barrier Function via Sphingosine -1 Phosphate Receptor 1 (S1PR1) – a Novel Treatment for Experimental Arthritis
Background/Purpose: S1PR1 signaling plays critical roles in EC barrier function and vascular health, but until now, research on S1PR1 modulation in autoimmune rheumatic disease has…Abstract Number: 1021 • ACR Convergence 2021
Organic Dust Exposure Induces Post-translational Protein Modifications and a HLA-DR4-dependent Pro-inflammatory Lung Phenotype in a Murine Model of Interstitial Lung Disease
Background/Purpose: Environmental and occupational exposures have been epidemiologically linked to the development of rheumatoid arthritis-associated interstitial lung disease (RA-ILD). Previous investigation and modeling have also…Abstract Number: 1432 • ACR Convergence 2021
Modulation of Auto-Inflammation with a Novel Selective Cyclic GMP-AMP Synthase (cGAS) Inhibitor in a Trex1-/- Model
Background/Purpose: The detection of viral nucleic acids (NA) elicits a transient type I interferon (IFN) response central to antiviral immunity. Chronic type I IFN responses…Abstract Number: 1468 • ACR Convergence 2021
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…
