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: 794 • 2015 ACR/ARHP Annual Meeting
CD163+ Macrophages Display Mixed Polarizations in Discoid Lupus Skin

Divergent Phenotypic Patterns Between Systemic Lupus Erythematosus and Healthy Anti-Nuclear Antibody Positive Individuals Reveal Distinct Differences in B Cell and Myeloid Populations Among Ethnicities
Background/Purpose: Systemic lupus erythematosus (SLE) is an autoimmune disorder that arises from genetic and environmental factors. Thus, patients with different ancestral backgrounds display differences in…Abstract Number: 798 • 2015 ACR/ARHP Annual Meeting
Keratinocyte-Associated IL-6 Is Elevated in Cutaneous Lupus Rashes and Production of IL-6 By Keratinocytes Is Enhanced in Non-Involved Lupus Skin
Background/Purpose: Systemic lupus erythematosus (SLE) is a devastating autoimmune disease with severe complications such as immune-complex mediated nephritis and scarring skin lesions. Treatment modalities for…Abstract Number: 799 • 2015 ACR/ARHP Annual Meeting
Transcriptional Profiling of Cutaneous Lupus Reveals Pronounced Changes in Keratinocyte and Myeloid Lineage Expressed Genes and Demonstrates Uniquely Regulated Interferon Pathways Between Rash Subtypes
Background/Purpose: Cutaneous lupus rashes can be substantial, disfiguring, and often refractory to usual lupus therapies. Phenotypic presentation and risk of systemic lupus manifestations differs by…Abstract Number: 800 • 2015 ACR/ARHP Annual Meeting
A High-Throughput System for Quantification of in Vitro Neutrophil Extracellular Trap Formation with Fluorescence Immunocytochemistry
Background/Purpose: Neutrophil extracellular traps (NETs) consist of decondensed chromatin and antimicrobial peptides and are able to trap and kill pathogens. Several studies suggest a pathogenic…Abstract Number: 801 • 2015 ACR/ARHP Annual Meeting
Artesunate Modulates Atherosclerosis Related Factors through the Inhibition of STAT1
Background/Purpose: While type I interferon (IFN) has been linked to atherosclerosis progression in systemic lupus erythematosus (SLE), little is known about its regulation and intervention.…Abstract Number: 802 • 2015 ACR/ARHP Annual Meeting
Identification of Cyclin-Dependent Kinase 1 As a Novel Regulator for Controlling Type I Interferon Signaling in Systemic Lupus Erythematosus
Background/Purpose: Type I interferon (IFN) signaling has been a central pathogenic pathway in systemic lupus erythematosus (SLE). The application of specific inhibitors of IFN pathway has emerged…Abstract Number: 803 • 2015 ACR/ARHP Annual Meeting
Interferon-Alpha Mediated Lowering of Pentraxin-3 Levels in Systemic Lupus Erythematosus?
Background/Purpose: The type I interferon (IFN) system is important in the pathogenesis of systemic lupus erythematosus (SLE). We have previously shown an inhibitory effect of…Abstract Number: 804 • 2015 ACR/ARHP Annual Meeting
Prolactin Induces Interferon Regulatory Factor 1 Activation and Histone H4 Hyperacetylation in Primary Monocytes Comparable to Changes Seen in Monocytes from Systemic Lupus Erythematosus Patients
Background/Purpose: : Epigenetic changes have been described in systemic lupus erythematosus (SLE) and offer a potential explanation for the chronicity of disease. We previously found…Abstract Number: 805 • 2015 ACR/ARHP Annual Meeting
Interferon Activity in Early and Established SLE: Interferon Score Is Lower in Early Disease and Not Seen without Antibodies to Extractable Nuclear Antigens
Background/Purpose: SLE patients have increased expression of interferon-stimulated genes (ISG) and multiple autoantibodies. Some patients initially present with early incomplete SLE (E-ILE) with ANA but…Abstract Number: 806 • 2015 ACR/ARHP Annual Meeting
STAT1 Activation Promotes TLR8 Overexpression and Facilitates Mirokine Signaling Via Exosomes Containing a Mir-21 Endogenous Ligand: A Novel Innate Inflammatory Pathway in Systemic Lupus Erythematosus
Background/Purpose: The adaptive arm of the immune system plays a significant role in the pathophysiology of Systemic Lupus Erythematosus (SLE). However, recent studies suggest that…Abstract Number: 807 • 2015 ACR/ARHP Annual Meeting
High Levels of Serum IFN-Alpha Mark a Subgroup of SLE Patients with Distinct Immunophenotypic Features and Hyperresponsiveness to Toll-like Receptor Stimulation
Background/Purpose: IFN-alpha is a pathogenic factor in SLE. High serum interferon activity (IFN-high) marks a subgroup of SLE patients strongly associated with increased disease severity…
