The Role of Dual Specificity Phosphatase 22 (DUSP22) in Rheumatoid Arthritis: Mechanism and Genetic Investigations
Background/Purpose: Rheumatoid arthritis (RA) is a debilitating autoimmune disorder characterized by chronic inflammation and joint damage. This study investigates the role of Dual Specificity Phosphatase…Abstract Number: 0836 • ACR Convergence 2024
NF-κB Inducing Kinase Is a Therapeutic Target for Autoimmune Diseases by Orchestrating Both B Cell and T Follicular Helper Cell Responses
Background/Purpose: T follicular helper (Tfh) cells are a specialized CD4+ T cell subset which can help B cells in the germinal center (GC) to drive…Abstract Number: 0840 • ACR Convergence 2024
The Platelet Adenosinergic Axis as a Novel Therapeutic Target for Thrombotic APS
Background/Purpose: How to most effectively inhibit antiphospholipid antibodies (aPL)-mediated platelet activation remains incompletely understood. CD73 is an ectoenzyme expressed on the platelet surface that generates…Abstract Number: 0879 • ACR Convergence 2024
A Novel, Oral, Allosteric Inhibitor of Tyrosine Kinase 2 (TYK2) Demonstrates In Vitro Potency, Selectivity, and In Vivo Efficacy in Mouse Models of Psoriasis
Background/Purpose: Tyrosine kinase 2 (TYK2), a member of the Janus kinase (JAK) family, plays a key role in several inflammatory diseases. Orthosteric, small molecule inhibitors…Abstract Number: 0932 • ACR Convergence 2024
IRAK4 Degrader GS-6791 Inhibits TLR and IL-1R-Driven Inflammatory Signaling, and Ameliorates Disease in a Preclinical Arthritis Model
Background/Purpose: Despite advances in treatment, chronic inflammatory diseases such as rheumatoid arthritis (RA) represent areas of high unmet medical need. IRAK4 is a proximal mediator…Abstract Number: 2596 • ACR Convergence 2024
Clock Gene Bmal1 Contributes to Inflammation via Phosphorylation of NF-κB/p65 in RA-FLS
Background/Purpose: Inflammatory cytokines such as TNF-α, IL-6, and IFN-γ show their peaks at midnight in sera of patients with rheumatoid arthritis (RA), which is thought…Abstract Number: 0021 • ACR Convergence 2024
A Novel Small Molecule Screening Assay Using Normal Human Chondrocytes Toward Osteoarthritis Drug Discovery
Background/Purpose: A central feature of osteoarthritis (OA) is progressive cartilage degradation driven by increased production of matrix degrading enzymes including MMP-13. There is a critical…Abstract Number: 0023 • ACR Convergence 2024
Adenosine and Guanosine-based Oligonucleotide Attenuates Catabolic Phenotypes in Chondrocytes and Slows Progression of Surgically Induced Osteoarthritis
Background/Purpose: Adenosine is a potent endogenous modulator of inflammation; however, its clinical application is limited due to its extremely short half-life in blood. In this…Abstract Number: 0011 • ACR Convergence 2023
Clock Gene Bmal1 Promotes Transcriptional Activity of NF-κB to Regulate Production of Inflammatory Mediators in RA-FLS
Background/Purpose: Rheumatoid arthritis (RA), an autoimmune polyarthritis characterized by 'tumor-like' proliferation of RA fibroblast-like synovial cells (RA-FLS), has characteristic symptoms such as "morning stiffness of…Abstract Number: 0799 • ACR Convergence 2023
Human Chimeric Antigen Receptor (CAR)-Tregs Targeting OX40L for Treatment of Systemic Lupus Erythematosus
Background/Purpose: Chimeric Antigen Receptor Regulatory T cells (CAR-Tregs) are an emerging strategy to restore immune tolerance during auto- or allo-immune conditions. However, most autoimmune diseases…Abstract Number: 0942 • ACR Convergence 2023
G Protein-coupled Receptor Kinase 5 in Fibrotic Tissue Remodeling
Background/Purpose: G-protein coupled receptor kinase 5, GRK5, is a central regulator of G protein-coupled receptors (GPCRs), a vast family of cell surface receptors involved in…Abstract Number: 0964 • ACR Convergence 2023
Systemic Sclerosis (SSc) Dermal Fibroblasts Show Shortened Primary Cilia Due to Aberrant Aurora a Kinase Activation Independently of Transforming Growth Factor β Signalling
Background/Purpose: Systemic Sclerosis (SSc) is an autoimmune disorder characterised by abnormal activation of tissue fibroblasts, resulting in tissue and vascular fibrosis of the skin and…Abstract Number: 1602 • ACR Convergence 2023
NADPH Oxidase Exerts a B Cell-intrinsic Contribution to Lupus Risk by Modulating Endosomal Toll-like Receptor (TLR) Signals
Background/Purpose: Genome-wide association studies in systemic lupus erythematosus (SLE) have linked loss-of-function mutations in phagocytic NADPH oxidase complex (NOX2) genes, including NCF1 and NCF2, to…Abstract Number: 1778 • ACR Convergence 2023
Role of GITR/GITRL Interaction in Modulating T Helper 9, T Helper 17 and T Regulatory Response in Psoriatic Arthritis
Background/Purpose: The inflammatory process characterizing Psoriatic Arthritis (PsA) is mainly driven by interleukin (IL)-23/IL-17 axis and IL-9 overexpression, in presence of T helper (Th)17 and…Abstract Number: 1787 • ACR Convergence 2023
Regulatory Role of JAK-1/TYK2 Signaling on the Pannus Formation: Novel Mechanisms for JAK Inhibitors in Psoriatic Disease
Background/Purpose: In psoriatic arthritis (PsA) aberrant activation/migration of specific T cell subpopulations (Th17/Th9/MAIT cells) in the joint synovium induce synovial inflammation and pannus formation. Several…
