A Dual Role for IL-23 Receptor Signaling in Normal Bone Remodeling Versus Inflammation-Mediated Bone Damage during Arthritis
Background/Purpose: The interleukin (IL)-23/IL-17A immune pathway is critical for the development of autoimmune arthritis. Systemic exposure of IL-23 induced chronic arthritis, increased osteoclast differentiation and…Abstract Number: 11L • 2016 ACR/ARHP Annual Meeting
BMS-986165 Is a Highly Potent and Selective Allosteric Inhibitor of Tyk2, Blocks IL-12, IL-23 and Type I Interferon Signaling and Provides for Robust Efficacy in Preclinical Models of Systemic Lupus Erythematosus and Inflammatory Bowel Disease
Background/Purpose: Tyk2 mediates signaling downstream of the receptors for IL-12, IL-23 and Type I interferons, all key drivers of autoimmune disorders such as SLE. BMS-986165,…Abstract Number: 2715 • 2016 ACR/ARHP Annual Meeting
Genetic Variants in TNF, TNFRSF1A, and IL23R Are Associated with Risk of Ankylosing Spondylitis
Background/Purpose: The objective of this study was to evaluate single nucleotide polymorphisms (SNPs) involved in TNFα signaling, NF-κB activation, interferon-γ signaling, or pattern recognition receptor…Abstract Number: 960 • 2016 ACR/ARHP Annual Meeting
Ultrasonographic Improvement of Peripheral Subclinical Enthesopathy in Therapy-Naive Patients Treated with Ustekinumab for Chronic Plaque Psoriasis: A 52-Week, Prospective, Open Label, Controlled Cohort Study
Background/Purpose: Subclinical enthesopathy is recognised in up to 50% of psoriasis patients and is thought to precede inflammatory PsA. It is not known if effective…Abstract Number: 1678 • 2016 ACR/ARHP Annual Meeting
JAK STAT Kinase Cascade Regulates the IL-23/IL-17 Cytokine Axis in Psoriatic Arthritis
Background/Purpose: Aberrant activation of IL-23/IL-17 cytokine axis is a dominant pathology in the psoriatic disease. IL-23 regulates expansion/maintenance/functional maturation of Th17 cells. Th17 cells along…Abstract Number: 1752 • 2016 ACR/ARHP Annual Meeting
IL-23 Promotes the Generation of DNT Cells and Shifts the Balance Between IL-2 and IL-17 Production in Murine and Human SLE
Background/Purpose: MRL/lpr mice develop a chronic inflammatory disease characterized by accumulation of CD4-CD8-B220+T cells mimicking human lupus; IL-23 driven IL-17 producing cell contribute to lupus…Abstract Number: 2694 • 2016 ACR/ARHP Annual Meeting
Treatment of ZAP-70 Mutant SKG Mice with Anti-IL-23 Antibody Alters Fecal Microbiota Composition and Prevents Outgrowth of Bacteria Associated with Susceptibility to Spondyloarthritis and Ileitis
Background/Purpose: Identification of disease-associated or protective bacteria may elucidate new biomarkers or probiotic supplements for people suffering from spondyloarthritis (SpA), or for people at-risk of…Abstract Number: 2711 • 2016 ACR/ARHP Annual Meeting
Tissue-Resident IL-23 Responsive Innate T Cells in Mice Comprise Tcrαβ+ and TCRγδ+ Subsets with Overlapping Function
Background/Purpose: Multiple lines of evidence suggest a critical role for the IL-23/IL-17A axis in spondyloarthritis. In susceptible inbred strains, hydrodynamic injection of IL-23 minicircles into…Abstract Number: 199 • 2015 ACR/ARHP Annual Meeting
Human Type 1 and Ncr-Negative Type 3 Innate Lymphoid Cells Accumulate in the Inflamed Synovium in Spondyloarthritis
Background/Purpose: Spondyloarthritis (SpA) is a major form of chronic inflammatory arthritis characterized by inflammation of axial and peripheral joints and by pathologic new bone formation…Abstract Number: 2144 • 2015 ACR/ARHP Annual Meeting
Efficacy and Safety of Different Dose Regimens of a Selective IL-23p19 Inhibitor (BI 655066) Compared with Ustekinumab in Patients with Moderate-to-Severe Plaque Psoriasis with and without Psoriatic Arthritis
Background/Purpose: IL-23 is essential for the differentiation and maintenance of Th17 cells in psoriasis and psoriatic arthritis (PsA). We assessed the efficacy and safety of…Abstract Number: 2809 • 2015 ACR/ARHP Annual Meeting
Increased Frequencies of IL-23R Positive T Cells and IL-22 and IL-17 Producing MAIT Cells in the Peripheral Blood of Patients with Ankylosing Spondylitis: Preliminary Results.
Background/Purpose: Ankylosing spondylitis (AS) is the prototypic and most common form of spondyloarthritis (SpA). It was recently suggested that IL-23 could play a pivotal role…Abstract Number: 2819 • 2015 ACR/ARHP Annual Meeting
Rorc Antagonism Inhibits IL-23-Dependent Aberrant Bone Formation in Vivo
Background/Purpose: RORγt is a nuclear hormone receptor expressed in Th17 cells and distinct subsets of lymphoid cells, including innate lymphoid cells (ILC), and γδ T-cells.…Abstract Number: 2822 • 2015 ACR/ARHP Annual Meeting
