Increase in Macrophage Infiltration in Scleroderma Esophageal Mucosa Is Associated with Motility and Mucosal Complications
Background/Purpose: The macrophage activation is elevated in systemic sclerosis (SSc) patients, and is implicated in pathogenesis of tissue inflammation, fibrosis, and the development of skin…Abstract Number: 2440 • ACR Convergence 2023
Synovial Shaping of Skin-derived Migrating Immune Cells Determines Initiation of Inflammation in Psoriatic Arthritis
Background/Purpose: Around 30% of the patients with psoriasis (PsO) develop psoriatic arthritis (PsA) overtime, suggesting the existence of a disease mediated skin-joint crosstalk. To date,…Abstract Number: 0035 • ACR Convergence 2023
Using Genotyping and Functional Data from Monocytes to Identify Risk-Driving SNPs on JIA Risk Haplotypes
Background/Purpose: GWAS have identified multiple genetic regions that confer risk for juvenile idiopathic arthritis (JIA).However, identifying the single nucleotide polymorphisms (SNPs) that drive disease risk…Abstract Number: 0041 • ACR Convergence 2023
Interactions Between Synovial Fibroblasts and Macrophages: Implications for Tissue Remodeling in Chronic Inflammatory Diseases and Macrophage Differentiation in Response to the Immune Microenvironment
Background/Purpose: Activated macrophages (Mph) can be subdivided in at least 2 major subgroups according to their polarization into classical pro-(M1-Mph) or anti-inflammatory (M2-Mph) subtypes. Together…Abstract Number: 0054 • ACR Convergence 2023
RA Monocytes and Monocyte-Derived Macrophages Display Heightened Inflammatory Responses, Reduced Endocytic Capacity and Distinct TET Expression Compared to PsA Monocytes
Background/Purpose: RA and PsA share various pathogenic features, while also displaying significant differences at the clinical, cellular and molecular levels. In this study, we investigate…Abstract Number: 0061 • ACR Convergence 2023
Discovery of a RIPK2 Scaffolding Inhibitor for the Treatment of Joint Autoimmune Diseases
Background/Purpose: Receptor interacting protein kinase 2 (RIPK2) is a key signaling node for inflammation caused by peptidoglycan (PGN). In the intestine, RIPK2 integrates signaling originating…Abstract Number: 037 • 2023 Pediatric Rheumatology Symposium
Transcriptional Analysis of CD14+ Monocytes During Macrophage Activation Syndrome Highlights Role for Interferons and RNA Sensing in Monocytes
Background/Purpose: Macrophage activation syndrome (MAS), a form of secondary hemophagocytic lymphohistiocytosis (HLH), is a potentially fatal complication of rheumatic diseases. MAS is a dysfunctional hyperinflammatory…Abstract Number: 0652 • ACR Convergence 2022
Serum from Patients with SLE and Anti-MDA5 Antibody-Positive Dermatomyositis Induce Shared Monocyte Cytokine Signature Through Type 1 Interferon Pathway
Background/Purpose: Although type 1 interferon (IFN) plays a pivotal role in the pathogenesis of systemic lupus erythematosus (SLE) and polymyositis/dermatomyositis (PM/DM) [1] as typically evidenced…Abstract Number: 0654 • ACR Convergence 2022
Lymphatic Dysfunction and Immune Activation in Lupus
Background/Purpose: Systemic lupus erythematosus is a prototypic autoimmune disease in which patients frequently have photosensitivity. Exposure to ultraviolet radiation (UVR) causes the eruption of cutaneous…Abstract Number: 0663 • ACR Convergence 2022
Anti-Erythrocyte Antibodies in Childhood Onset Systemic Lupus Erythematosus
Background/Purpose: Systemic Lupus Erythematosus (SLE) is a disease characterized by the presence of auto-antibodies, immune complex deposition, and a robust type 1 interferon signature. It…Abstract Number: 1167 • ACR Convergence 2022
Towards an Autologous 3D Skin-like Tissue Harboring Patient-Derived Fibroblasts, Keratinocytes, T-cells and Macrophages
Background/Purpose: Scleroderma (Systemic Sclerosis; SSc) is an autoimmune disease of unknown etiology that is characterized by vascular dysfunction, fibrosis, and inflammation. A lack of human…Abstract Number: 1169 • ACR Convergence 2022
Downregulated Fli1 in Systemic Sclerosis Myeloid Cells Contributes to Enhanced Transendothelial Migration
Background/Purpose: The mononuclear phagocytic system in Systemic Sclerosis (SSc) is central to fibrogenesis and may contribute to fibrosis via enhanced monocyte migration into injured tissues…Abstract Number: 1565 • ACR Convergence 2022
Dissection of Ocular and Peripheral Blood Immune Phenotypes Suggests Preferential Transmigration of CD16+ Monocytes to Effector Sites in Behçet’s Disease
Background/Purpose: Cellular immunity of Behçet's Disease (BD) remains poorly understood. Previous work has provided clues pointing to most innate and adaptive immune cell types in…Abstract Number: 1699 • ACR Convergence 2022
