Autoantibody Mediated Salivary Gland Hypofunction in Sjögren’s Syndrome Involves Activation of Innate Immunity and Endothelial Cells
Background/Purpose: The presence of autoantibodies reactive against the Ro52/TRIM21 protein is a hallmark of Sjögren’s syndrome. We have reported that Ro52-immunized mice develop IgG deposits…Abstract Number: 2075 • 2018 ACR/ARHP Annual Meeting
Vascular Endothelial and Inflammatory Differences in Psoriasis and Psoriatic Arthritis Patients
Background/Purpose: Psoriatic arthritis (PsA) and Psoriasis (PsO) are chronic inflammatory diseases associated with vascular inflammation and increased CVD risk. Few studies have examined vascular inflammatory…Abstract Number: 2076 • 2018 ACR/ARHP Annual Meeting
Transmembrane TNF (tmTNF) Transgenic Mice Exhibit Enlarged Lymph Nodes and Elevated Numbers of High Endothelial Cells Associated with Increased Lymphocyte Recruitment
Background/Purpose: The NF-κB family of transcription factors plays a crucial role in chronic inflammatory diseases and can be activated via two distinct pathways. Non-canonical NF-κB…Abstract Number: 92 • 2018 ACR/ARHP Annual Meeting
Lupus Nephritis Serum Induces Neutrophil Chemotaxis Towards Glomerular Endothelial Cells in Vitro
Title: Lupus Nephritis Serum Induces Neutrophil Chemotaxis towards Glomerular Endothelial Cells In Vitro Background/Purpose: Systemic lupus erythematosus (SLE) is a chronic inflammatory disease associated with…Abstract Number: 2010 • 2018 ACR/ARHP Annual Meeting
Anti-Endothelial Cell Antibodies in Pediatric Rheumatic Diseases
Background/Purpose: Anti-endothelial cell antibodies (AECA) are antibodies detected in multiple autoimmune and inflammatory diseases. Increased levels of such antibodies may be involved in disease activity…Abstract Number: 8 • 2017 ACR/ARHP Annual Meeting
Antiphospholipid Syndrome Leukocytes Demonstrate Increased Adhesive Potential: a Search for Novel Therapeutic Targets
Background/Purpose: Adhesion of leukocytes to the endothelium is an initiating event in the thrombosis inherent to antiphospholipid syndrome (APS). Over the years, a number of…Abstract Number: 686 • 2017 ACR/ARHP Annual Meeting
Endothelial Dysfunction in Systemic Lupus Erythematosus Patients without Cardiovascular events and Risk Factors: Correlation with Microvascular Alterations and angiogenic t Cells
