High Level of CD38 Expression in SLE CD8 T Cells Dictates Decreased Cytotoxicity
Background/Purpose: CD38 is an ectonucleotidase that has the ability to degrade nicotinamide adenine dinucleotide (NAD). The percentage of CD38 expressing CD8 T cells are increased…Abstract Number: 149 • 2018 ACR/ARHP Annual Meeting
Deep Immune-Profiling of CD4+ T Cells in Behçet’s Disease
Background/Purpose: Functionality and immune-phenotypes of the human CD4+ T-cell compartment in Behçet’s disease (BD) are under-investigated, but several lines of evidence point to its relevance…Abstract Number: 150 • 2018 ACR/ARHP Annual Meeting
PD-1 Signaling Interferes with OX40L to Alter the Suppressive Function and Proliferation of CD4+ Regulatory T Cells in Lupus Mice
Background/Purpose: In systemic lupus erythematosus (SLE), the dysregulated production of autoantibodies is a consequence of disrupted T cell homeostasis. Programmed death-1 (PD-1), a negative regulator…Abstract Number: 151 • 2018 ACR/ARHP Annual Meeting
Molecular Mechanisms of Pathogenic T Cell Resilience in Human Arthritis
Background/Purpose: T-cell resilience is critical to the immune pathogenesis of human autoimmune arthritis. Autophagy is essential for memory T cell generation and is associated with…Abstract Number: 152 • 2018 ACR/ARHP Annual Meeting
Polymorphonuclear Neutrophils and Regulatory T Lymphocytes (Treg) Cooperate to Sustain Treg Activity in Normal and Arthritic Contexts
Background/Purpose: Polymorphonuclear neutrophils (PMN) are abundant and activated in rheumatoid arthritis (RA) joints. In addition to their pro-inflammatory role, PMN exert immunoregulatory functions and may…Abstract Number: 153 • 2018 ACR/ARHP Annual Meeting
Chemotaxis of Vδ2 T Cells to the Joints Contributes to the Pathogenesis of Rheumatoid Arthritis
Background/Purpose: To explore the role of Vδ2 t cells in the pathogenesis of rheumatoid arthritis (rA) Methods: Sixty-eight patients with RA, 21 patients with osteoarthritis…Abstract Number: 154 • 2018 ACR/ARHP Annual Meeting
Epigenetic Editing of FOXP3 in Human T Cells Is Sufficient to Induce Overexpression and Create a Regulatory T Cell Phenotype in Vitro
Background/Purpose: Defects in the number and function of naturally-occurring regulatory T cells (Tregs) have been identified in a variety of autoimmune diseases. The development of…Abstract Number: 155 • 2018 ACR/ARHP Annual Meeting
Polyfunctional Synovial T-Cell Responses and Synovial Invasiveness Repressed By Blockade of Phosphodiesterase 4
Background/Purpose: Genetic and functional studies strongly support the role of T-cells in PsA pathophysiology. Effective targeting of T-cells requires a detailed understanding of their phenotypic…Abstract Number: 156 • 2018 ACR/ARHP Annual Meeting
Assessing the Role of Ascvd Score in Primary Thrombosis Prophylaxis Strategy Among Asymptomatic Antiphospholipid Antibody Carriers
Background/Purpose: Primary thrombosis prophylaxis among asymptomatic antiphospholipid antibody (aPL) carriers is challenging. The presence of aPL does not always lead to thromboembolic events. Additional factors…Abstract Number: 157 • 2018 ACR/ARHP Annual Meeting
Identifying Additional Risk Factors Associated with Thrombosis and Pregnancy Morbidity in a Unique Cohort of Antiphospholipid Antibody Positive Chinese Patients
Background/Purpose: Risk stratification of asymptomatic aPL carriers is difficult. Our objective was to identify additional clinical and epidemiological predictors of arterial thrombosis, venous thrombosis, and…
