Genetic Deletion of Toll-like Receptor 4 (Tlr4) Abrogates TGF-β1-Induced Endothelial-to-Mesenchymal Transition (EndoMT) in Murine Pulmonary Endothelial Cells
Background/Purpose: Systemic sclerosis (SSc) is a systemic autoimmune disease of unknown etiology whose pathogenesis involves the regulation of a diverse range of molecular pathways. The…Abstract Number: 1880 • 2015 ACR/ARHP Annual Meeting
Circulating Microparticle Populations May Differentiate Between Connective Tissue Diseases.
Background/Purpose: Microparticles (MPs) are membrane-bound vesicles derived from vascular and intravascular cells such as endothelial cells (EMPs) and platelets (PMPs). Circulating MPs levels are altered…Abstract Number: 1175 • 2015 ACR/ARHP Annual Meeting
Blood Outgrowth Endothelial Cells Isolated from Systemic Sclerosis Patients Exhibit a Pro-Inflammatory Phenotype
Background/Purpose: Vascular complications are a key pathological feature of systemic sclerosis (SSc) affecting the microcirculation and arterioles. Under normal circumstances the endothelium acts as a…Abstract Number: 591 • 2015 ACR/ARHP Annual Meeting
Rosuvastatin Improves Endothelial Function in Patients with Inflammatory Joint Diseases, Longitudinal Associations with Atherosclerosis and Arteriosclerosis
Background/Purpose: Endothelial dysfunction is an early step in the formation of atherosclerotic lesions and can be quantified by the degree of flow mediated vasodilation (FMD)…Abstract Number: 4 • 2015 ACR/ARHP Annual Meeting
The Influence of Adipokines on the Interaction of Rheumatoid Arthritis Synovial Fibroblasts with Endothelial Cells
Background/Purpose: Rheumatoid Arthritis (RA) is a systemic chronic inflammatory disease. Adipose tissue, being an endocrine organ, plays an important role in inflammatory processes. Adipokines are…Abstract Number: 3085 • 2015 ACR/ARHP Annual Meeting
Platelet Activation and Endothelial Reactivity in the Pathogenesis of Tissue Inflammation/Injury in Systemic Lupus Erythematosus
Background/Purpose: Patients with systemic lupus erythematosus (SLE) are at increased risk for widespread endothelial dysfunction, vascular thromboses, and premature cardiovascular disease. Enhanced platelet activation and…Abstract Number: 3003 • 2014 ACR/ARHP Annual Meeting
Am80 Ameliorates Bleomycin-Induced Dermal Fibrosis By Suppressing the Pro-Fibrotic Phenotype of Fibroblasts, Endothelial Cells, and Immune Cells
Background/Purpose: Am80 is a synthetic retinoid serving as an agonist for retinoic acid receptor α/β with chemical and pharmacological advantages over all-trans retinoic acid, such…Abstract Number: 2445 • 2014 ACR/ARHP Annual Meeting
A Distinct Profile of Circulating Microparticles Is Associated with Disease Features in Rheumatoid Arthritis Patients and Impairs Endothelial Functionality in Vitro
Background/Purpose Cell-derived microparticles (MPs) could be considered biomarkers of cell damage and activation and they are thought to have a role in cardiovascular (CV) and inflammatory…Abstract Number: 1980 • 2014 ACR/ARHP Annual Meeting
Thrombospondin-1 Is Elevetad in the Plasma of Patients with Antiphospholipid Syndrome and Is Correlated with Soluble Fas Ligand and Free Active TGF-B levels
Background/Purpose Antiphospholipid syndrome (APS) is an acquired thombophillia characterized by recurrent thromboembolism and pregnancy morbidity. Thrombospondin (TSP-1) is a matricellular glycoprotein with antiangiogenic and proapoptotic…Abstract Number: 1717 • 2014 ACR/ARHP Annual Meeting
Endothelial to Mesenchymal Transition Contributes to the Development of Pulmonary Vasculopathy in Systemic Sclerosis PAH
Background/Purpose Vascular complications in Scleroderma (SSc) patients are associated with high mortality, particularly in patients who develop pulmonary arterial hypertension (SSc-PAH). Vascular complications, thought to…
