Mesenchymal Stem Cells Promote the Generation of CD206+ Macrophage and Increase Its Phagocytic Activity in Systemic Lupus Erythematosus
Background/Purpose: Umbilical cord (UC)-derived mesenchymal stem cells (MSCs) have been confirmed to exert therapeutic effects on systemic lupus erythematosus (SLE). Deficiency in SLE macrophages exhibits…Abstract Number: 1033 • 2015 ACR/ARHP Annual Meeting
Novel Ligand-Independent Peptide Inhibitors of Triggering Receptor Expressed on Myeloid Cells 1 (TREM-1) and T Cell Receptor (TCR): Efficacy in a Collagen-Induced Arthritis Model Suggests New Targeted Treatment for Rheumatoid Arthritis
Background/Purpose: Macrophages and T cells are central to the pathophysiology of autoimmune diseases. Synovial macrophages, synovial fibroblasts and infiltrating T lymphocytes are the most abundant…Abstract Number: 2151 • 2015 ACR/ARHP Annual Meeting
Inhibition of Myeloid-Associated Gene Expression in Skin Biopsy Samples of Systemic Sclerosis Patients Treated with Tocilizumab
Background/Purpose: Systemic sclerosis (SSc) is a progressive, debilitating disease with limited treatment options. IL-6 has been implicated in disease pathogenesis. Tocilizumab (TCZ), an IL-6Rα inhibitor,…Abstract Number: 1198 • 2014 ACR/ARHP Annual Meeting
Prolactin Is Locally Produced in the Synovium of Patients with Inflammatory Arthritic Diseases and Promotes Macrophage Activation
Background/Purpose The sex hormone prolactin (PRL) has immunomodulatory properties, can be produced by immune cells, and elevated PRL serum levels have been reported in rheumatoid…Abstract Number: 2875 • 2014 ACR/ARHP Annual Meeting
Macrophage Expression of Hypoxia-Inducible Factor-2 Alpha Promotes Rheumatoid Arthritis Progression
Background/Purpose Hypoxia exists in many diseased tissues including arthritic joints, atherosclerotic plaques and malignant tumours. Macrophages accumulate in these hypoxic sites where they possess broad…Abstract Number: 2175 • 2014 ACR/ARHP Annual Meeting
Macrophages from the Synovium of Active Rheumatoid Arthritis Exhibit an Activin a- Dependent Pro-Inflammatory Profile
Background/Purpose: Synovial macrophages are key effector cells in rheumatoid arthritis (RA), where they are a major source of pro-inflammatory cytokines and contribute to the cartilage…Abstract Number: 1510 • 2014 ACR/ARHP Annual Meeting
Blockade of TLR5 Ligation Is a Novel Strategy for RA Therapy
Background/Purpose: TLR5 expression is highly elevated in RA and CIA lining and sublining macrophages and endothelial cells compared to non-arthritic controls. Additionally, expression of TLR5…Abstract Number: 1151 • 2013 ACR/ARHP Annual Meeting
Snapin Is Required For Functional Autophagy and Is Critical For Monocyte To Macrophage Differentiation
Background/Purpose: Our recent data indicate that Snapin, a SNAP associated protein, is significantly increased in macrophages (MΦs) in rheumatoid arthritis (RA) synovial tissue and its…Abstract Number: 530 • 2013 ACR/ARHP Annual Meeting
Pattern Recognition Receptor Stimulated Cytokine Expression By Spondyloarthritis Patient Macrophages
Background/Purpose: Spondyloarthritis (SpA) encompasses a group of chronic inflammatory conditions involving axial arthritis that includes ankylosing spondylitis (AS). GWAS studies in AS have implicated multiple…Abstract Number: 1078 • 2012 ACR/ARHP Annual Meeting
Prolactin Is Increased in Responders to Anti-TNFá Treatment and the Role of the Prolactin Receptor in Rheumatoid Arthritis
Background/Purpose: Rheumatoid arthritis (RA) is the most common rheumatic disease which mainly affects women. In the last decade, it is known that prolactin (PRL) is…Abstract Number: 1057 • 2012 ACR/ARHP Annual Meeting
A Specific Inhibitor of Spleen Tyrosine Kinase, PRT062607, Is a Potent Modulator of Innate Immune Cell Function
Background/Purpose: Tumor Necrosis Factor-α (TNF-α) is an essential component of the inflammatory stimuli leading to rheumatoid arthritis (RA). Therapeutics targeting TNF-α are the standard of…Abstract Number: 901 • 2012 ACR/ARHP Annual Meeting
Colony-Stimulating Factor (CSF) Receptor 1 Blockade Overcomes Overlapping Effects of M-CSF and Interleukin-34 On Myeloid Differentiation and Gene Expression to Reduce Inflammation in Human and Murine Models of Rheumatoid Arthritis
Background/Purpose: Disease activity and response to therapy in RA correlates with changes in synovial macrophage numbers and their products. M-CSF or IL-34 stimulation of their…Abstract Number: 880 • 2012 ACR/ARHP Annual Meeting
Interferon Regulatory Factor 8 Regulates BAFF Production in Murine Macrophages and Is a Nexus for Cross Talk Between IFN-γ and TGF-β
Background/Purpose: Lupus is a systemic autoimmune disease that can lead to severe end-organ damage characterized by unabated inflammation and aberrant tissue repair. Macrophage dysregulation plays…Abstract Number: 882 • 2012 ACR/ARHP Annual Meeting
Anti-Inflammatory Effects of Phosphodiesterase 4 Inhibition Are Mediated by Mitogen-Activated Protein Kinase Phosphatase-1
Background/Purpose: MAP kinase phosphatase-1 (MKP-1) is a nuclear tyrosine/threonine phosphatase that limits p38 MAP kinase activity. MKP-1 KO mice display excessive inflammatory response, and exhibit…
