mtDNA Cybrids from OA Patients Are Less Efficient Using Glycolysis and Are More Susceptible to Apoptosis Under Stress Conditions
Background/Purpose: Previous studies have showed that chondrocytes from OA patients had mitochondrial alteration in comparison with healthy. However the role of mitochondria in the biological…Abstract Number: 810 • 2016 ACR/ARHP Annual Meeting
Microrna-125b As a Potential Anti-Fibrotic and Anti-Apoptotic Regulator in Systemic Sclerosis
Background/Purpose: MicroRNAs (miRs) are a class of small, noncoding RNAs that regulate many biological processes. Some microRNAs are involved in skin fibrosis. Here, we aimed…Abstract Number: 1747 • 2016 ACR/ARHP Annual Meeting
Dissecting the Role of Single Complement Deficiencies in a Novel Model for Apoptotic Cell-Induced Lupus
Background/Purpose: The role of complement in Systemic Lupus Erythematosus (SLE) is complex as complement deficiencies in early components of the classical pathway cause lupus with…Abstract Number: 1916 • 2016 ACR/ARHP Annual Meeting
Heightened MAIT Cell Sensitivity to MR1 Ligands Could Impact Control of Dysbiosis in Patients with Rheumatoid Arthritis and Ankylosing Spondylitis
Background/Purpose: Mucosal associated invariant T (MAIT) cells are an innate-like lymphocyte population predominant at mucosal sites, which express a semi-invariant T cell receptor restricted to…Abstract Number: 2060 • 2016 ACR/ARHP Annual Meeting
Bim Suppresses the Development of SLE By Limiting Macrophage Inflammatory Responses
Background/Purpose: The Bcl-2 family guards the mitochondrial apoptotic pathway. Among numerous Bcl-2 antagonists, only the loss of Bim in mice leads to the development of…Abstract Number: 2557 • 2016 ACR/ARHP Annual Meeting
Tumor Necrosis Factor (TNF) Sensitizes Rheumatoid Synovial Fibroblasts to TRPA1-Mediated Calcium Flux, Anti-Proliferation and Cell Death
Background/Purpose: In rheumatoid arthritis (RA), synovial fibroblasts (SF) are one main contributor of joint destruction since they resist apoptosis and secrete pro-inflammatory cytokines and matrix…Abstract Number: 2558 • 2016 ACR/ARHP Annual Meeting
Dissociation of the Inhibitory Apoptosis Stimulating Protein of p53 (iASPP) Binding with Transcription Factor p73 Induces Synovial Fibroblast Apoptosis in the Rheumatoid Joint
Background/Purpose: Apoptosis-resistant synovial fibroblasts (SFs) constitute the major cell component of pannus tissues in rheumatoid arthritis (RA). In tumor cells, the binding of inhibitory…Abstract Number: 2561 • 2016 ACR/ARHP Annual Meeting
A Novel Pharmacological Action of MTX on RA Fibroblast-like Synoviocytes Via Circadian Clock Genes
Background/Purpose: The circadian rhythm is disrupted in patients with rheumatoid arthritis (RA), and we have shown that tumor necrosis factor(TNF)-ƒ¿ inhibits the expression of circadian…Abstract Number: 3143 • 2016 ACR/ARHP Annual Meeting
The Caspase 8/RIPK3 Signaling Axis in Dendritic Cells Controls Joint Homeostasis Under Steady-State and Arthritic Conditions
Background/Purpose: Rheumatoid arthritis (RA) manifests in persistent synovial inflammation, cellular infiltration and pro-inflammatory cytokine production, and results in progressive joint destruction. Dendritic cells (DCs) have…Abstract Number: 1616 • 2015 ACR/ARHP Annual Meeting
Identification of Genes Regulating TRAIL-Induced Apoptosis in Rheumatoid Arthritis Fibroblasts-like Synoviocytes (RA FLS)
Background/Purpose: We previously described that sensitivity to TRAIL-induced apoptosis varied in rheumatoid arthritis (RA) fibroblasts-like-synoviocytes (FLS) from one patient to another, and was inversly correlated…Abstract Number: 2559 • 2015 ACR/ARHP Annual Meeting
PRO-Resolving Mediators Issued from Apoptotic CELL Efferocytosis (SUPERMAPO) Modulate Antigen Presenting CELL Properties Toward a Tolerogenic Profile: Efficacy in the Treatment of Collagen- Induced Arthritis
Background/Purpose: Pro-resolving mediators produced by macrophages eliminating apoptotic effector cells during the resolution of inflammation have been shown to stop inflammation, favor tissue repair and…Abstract Number: 2705 • 2015 ACR/ARHP Annual Meeting
AAA-Atpase p97-HDAC6 Controlled Poly-Ubiquitin Turnover Regulates Apoptotic and Autophagy-Associated Cell Death in Arthritis
Background/Purpose: The AAA-ATPase valosin containing protein (p97) and histone deacetylase 6 (HDAC6) interact with each other and are implicated in the degradation of ubiquitin-labelled proteins.…Abstract Number: 3003 • 2015 ACR/ARHP Annual Meeting
Increased Heparanase Expression in Keratinocytes Promotes Dermal Fibrosis in Scleroderma
Background/Purpose: Interactions between keratinocyte and dermal fibroblast via paracrine loop play an important role in wound repair and keloid formation. In this study, we investigated…Abstract Number: 3215 • 2015 ACR/ARHP Annual Meeting
Bim Suppresses the Development of SLE By Limiting Macrophage Inflammatory Responses
Background/Purpose: The Bcl-2 family guards the mitochondrial apoptotic pathway. Among numerous Bcl-2 antagonists, only the loss of Bim in mice leads to the development of…Abstract Number: 8 • 2015 ACR/ARHP Annual Meeting
Bay 11-7085 Induces Glucocorticoid Receptor Activation and Autophagy to Initiate Human Synovial Fibroblast Cell Death
Background/Purpose: BAY 11-7085 is an inhibitor of IκBα phosphorylation that leads to NF-κB inactivation and downregulation of inflammation in mouse model of asthma, in articular…
