Platelets Specifically Interact with Remigrating Neutrophils and Promote Immunogenic Cellular Death in Systemic Lupus
Background/Purpose: In SLE, platelet activation (express P-selectin+) follows the disease activity, which plays a role in thrombosis as well as in inflammation (1). Neutrophils express high levels of PSGL-1,…Abstract Number: 0057 • ACR Convergence 2023
GM-CSF receptor/SYK/JNK/FOXO1/CD11c Signaling Enhances Cell Migration to Promote Atherosclerosis
Background/Purpose: Atherosclerosis involves both dyslipidemia and chronic inflammatory disease; however, lipid-lowering agents do not completely eliminate the risks of cardiovascular events. In addition, chronic systemic…Abstract Number: 0795 • ACR Convergence 2023
The Focal Adhesion Protein Lasp1 Links the Arp2/3 Complex to Cell-to-cell Contact Formation in Arthritic Fibroblast-like Synoviocytes
Background/Purpose: In rheumatoid arthritis (RA), fibroblast-like synoviocytes (FLS) undergo a stable transformation leading to an aggressive phenotype that mediates cartilage damage through increased levels of…Abstract Number: 0963 • ACR Convergence 2023
Anti-Topoisomerase Antibody in dcSSc: Unravelling Its Intracellular Effects in Systemic Sclerosis
Background/Purpose: The presence of autoantibodies, especially directed towards topoisomerase I (ATA), in diffuse cutaneous Systemic Sclerosis (dcSSc) is known to be associated with severe clinical…Abstract Number: 0585 • ACR Convergence 2022
Baricitinib Inhibits Proinflammatoly Cytokine Production, Proliferation and Cell Migration in Human Lung Fibroblasts
Background/Purpose: Rheumatoid arthritis (RA) is a systemic autoimmune disease characterized by inflammation and joint destruction. Baricitinib is a selective small molecule inhibitor of JAK 1…Abstract Number: 0587 • ACR Convergence 2022
Increase of Intercellular Adhesion Molecule-1 Linked to Lung Damage of Interstitial Lung Disease in Patients with Autoimmune Diseases
Background/Purpose: Intercellular adhesion molecule-1 (ICAM-1) regulates leukocyte recruitment from circulation to sites of inflammation, being considered as a marker of underlying endothelial damage [1]. Moreover,…Abstract Number: 0607 • ACR Convergence 2022
Cadherin 6 Regulates Rheumatoid Arthritis Fibroblasts-Like Synoviocyte Aggressiveness
Background/Purpose: Rheumatoid arthritis (RA) fibroblast-like synoviocytes (FLS) display an aggressive behavior. Previous studies have implicated cadherins in FLS function in this phenotype, which are type…Abstract Number: 1356 • ACR Convergence 2022
Patient-perceived Disease Burden and Self-reported Medication Adherence in Systemic Autoimmune Diseases: A Monocentric Observational Study
Background/Purpose: Systemic autoimmune diseases (AID) are chronic conditions with significant burden related to the disease itself, its management, and treatments. Burden refers to the workload…Abstract Number: 0020 • ACR Convergence 2022
Redoxosomes Mediate a Feed-forward Loop of Cartilage Matrix Destruction Through α5β1 Integrin Signaling in Response to a Fibronectin Matrikine
Background/Purpose: Degradation of pericellular matrix proteins creates bioactive fragments called "matrikines" that include fibronectin fragments (FN-f). FN-f found in OA cartilage and synovial fluid exhibit…Abstract Number: 0031 • ACR Convergence 2021
A New Pharmacostatistical Model to Assess MTX-adherence in RA Patients
Background/Purpose: Methotrexate (MTX) is the first-line therapy for rheumatoid arthritis (RA). While therapeutic adherence is essential to the successful management of the patient, an estimated…Abstract Number: 0057 • ACR Convergence 2021
Molecular Profiling of Radiographic Axial Spondyloarthritis Patients Reveals an Association Between Innate and Adaptive Cell Populations and Therapeutic Response to Adalimumab
Background/Purpose: The response to treatment in spondylarthropaties is heterogeneous, due to factors yet to be better described. For that reason, it is important to find…Abstract Number: 0514 • ACR Convergence 2021
Extracellular Sulfatase-2 Mediates TNF-α Inflammatory Signaling in Human Rheumatoid Arthritis Synovial Fibroblasts
Background/Purpose: TNF-α drives RA synovial fibroblast (RASF)-mediated hyperplasia and joint tissue destruction. Extracellular sulfatase-2 (Sulf-2) influences receptor/ligand binding and subsequent signaling of chemokines, cytokines, and…Abstract Number: 0552 • ACR Convergence 2021
Long Non-coding RNA H19X as a Regulator of Endothelial Adhesion Molecules in Systemic Sclerosis
Background/Purpose: Long non-coding RNAs (lncRNAs) are non-coding transcripts involved in the regulation of gene expression; their role in disease development, to date, remains largely under…Abstract Number: 0286 • ACR Convergence 2020
An SLE-linked ITGAM Gene Variant Changes Mac-1 Structure, Signaling, and Surface Expression and Enhances IFNg Production and Antigen Presentation by B Cells
