OBJECTIVES: Glucocorticoid-induced Tumor-Necrosis-Factor-Receptor Family-related Protein (GITR), with its ligand (GITRL), plays an important role in CD4+ T-cell-mediated autoimmunity. This study aimed to investigate the underlying mechanisms of GITRL in primary Sjögren's Syndrome (pSS). METHODS: pSS patients and healthy controls were recruited. Serum GITRL and Th17-related cytokines were determinated. RNA-Sequencing was performed to decipher key signal pathways...

OBJECTIVES: Eph/Ephrin cell-cell signaling is emerging as a key player in tissue fibrogenesis. The aim of this study was to test the hypothesis that the receptor tyrosine kinase EphB2 mediates dermal fibrosis in systemic sclerosis (SSc). METHODS: We assessed normal and SSc human skin biopsies for EphB2 expression. The in vivo role of EphB2 in skin fibrosis was investigated by subjecting Ephb2-knockout mice to both bleomycin-induced and tight skin (Tsk1/+) genetic mouse models of skin fibrosis...

OBJECTIVE: Subsets of CD21-/low memory B cells (MBCs), including double-negative (DN, CD27- IgD- ) and Tbet+ CD11c+ cells, are expanded in chronic inflammatory diseases. In rheumatoid arthritis (RA), CD21-/low MBCs correlate with joint destruction. However, whether this is due to the Tbet+ CD11c+ subset, its function and pathogenic contribution to RA are unknown. This study aims to investigate the association between CD21-/low Tbet+ CD11c+ MBCs and joint destruction as well as other clinical parameters and to elucidate their functional properties in untreated RA patients (uRA)...

OBJECTIVE: Fibroblast-like synoviocytes (FLS) contribute to the pathogenesis of rheumatoid arthritis (RA), in part due to activation of the pro-inflammatory transcription factor NF-κB. Neddylation is modulated by the negative regulator of ubiquitin-like proteins-1 (NUB1). We determined whether NUB1 and neddylation are aberrant in RA FLS thereby contributing to their aggressive phenotype. METHODS: RA or osteoarthritis (OA) FLS were obtained from arthroplasty synovia...

OBJECTIVE: To determine the event-free survival of Australian patients with diffuse systemic sclerosis (dcSSc), who meet eligibility criteria for autologous stem cell transplant (ASCT) in previously published randomised controlled trials (RCTs), but were managed without ASCT. METHODS: Patients who met inclusion criteria for the ASTIS (Autologous Stem Cell Transplantation International Scleroderma)(1) and SCOT (Scleroderma: Cyclophosphamide Or Transplantation)(2) trials were identified from the multicentre Australian Scleroderma Cohort Study (ASCS)...

INTRODUCTION: Spinal radiographic progression is an important outcome in radiographic axial spondyloarthritis (r-axSpA). SURPASS is the first head-to-head phase IIIb study comparing such changes in patients with r-axSpA treated with secukinumab (IL-17A inhibitor) versus adalimumab biosimilar (Sandoz adalimumab [SDZ-ADL]; TNF inhibitor). METHODS: Biologic-naïve patients with active r-axSpA, at high risk of radiographic progression (high-sensitivity C-reactive protein [hsCRP] ≥5 mg/L and/or ≥1 syndesmophyte[s] on spinal radiographs) were randomized (1:1:1) to secukinumab (150/300 mg) or SDZ-ADL (40 mg)...

OBJECTIVE: Rheumatoid arthritis (RA) is an autoimmune disease in which the joint lining, or synovium, becomes highly inflamed and majorly contributes to disease progression. Understanding pathogenic processes in RA synovium is critical for identifying therapeutic targets. We performed laser capture microscopy (LCM) followed by RNA sequencing (LCM-RNAseq) to study regional transcriptomes throughout RA synovium. METHODS: Synovial lining, sublining, and vessels were captured by LCM from seven RA and seven osteoarthritis (OA) patients...

OBJECTIVE: Oxylipins are bioactive lipids derived from polyunsaturated fatty acids (PUFAs) that modulate inflammation and may remain overexpressed in refractory synovitis. In plasma, they could also be biomarkers of synovial pathology. The aim of this study is to determine if synovial oxylipins in inflamed joints correlate with plasma oxylipins and with synovial histological patterns. METHODS: Patients with established rheumatoid or psoriatic arthritis with active disease despite treatment were recruited and paired ST and plasma were collected...

The discovery of interferon in the 1950s represents much more than the identification of the first cytokine and the key mediator of anti-viral host defense. Defining the molecular nature and complexity of the type I interferon family, as well as its inducers and molecular mechanisms of action, was the work of investigators working at the highest level and producing insights of great consequence. Current knowledge of receptor-ligand interactions, cell signaling, and transcriptional regulation derive from studies of type I interferon...

OBJECTIVE: In the randomized Scleroderma: Cyclophosphamide Or Transplantation (SCOT trial), myeloablation, followed by hematopoietic stem cell transplantation (HSCT), led to normalization of systemic sclerosis (SSc) peripheral blood gene cell (PBC) expression signature at the 26-month visit. Herein, we examined long-term molecular changes ensuing 54 months after randomization for individuals receiving an HSCT or 12 months of intravenous cyclophosphamide (CYC). METHOD: Global PBC transcript studies were performed at pretreatment baseline, 38 months, and 54 months post-randomization, as well as in healthy controls using Illumina HT-12 arrays...

OBJECTIVE: Relapses of ANCA-associated vasculitis are important events that can cause organ dysfunction and reduce quality of life. Understanding the effects of the initial treatments for ANCA-associated vasculitis on the subsequent risk of relapse may help guide monitoring and treatment. METHODS: We performed a post hoc analysis of participants with severe ANCA-associated vasculitis enrolled in an international, two-by-two factorial randomized controlled trial comparing the effects of plasma exchange (PLEX) to no PLEX and a regimen of reduced glucocorticoid exposure to a standard regimen...

OBJECTIVE: Lysosome-associated membrane protein 3 (LAMP3) misexpression in salivary gland epithelial cells plays a causal role in the development of salivary gland dysfunction and autoimmunity associated with Sjögren's disease (SjD). This study aimed to clarify how epithelial LAMP3 misexpression is induced in SjD. METHODS: To explore upstream signaling pathways associated with LAMP3 expression, we conducted multiple RNA sequencing analyses of minor salivary glands from patients with SjD, submandibular glands from a mouse model of SjD, and salivary gland epithelial cell lines...

Rare and complex rheumatic diseases (RDs) present with immense clinical variability inherent to all immunological diseases. In addition to systemic and organ-specific inflammation, patients may display features of immunodeficiency or allergy, and as such, they may represent major diagnostic and therapeutic challenges. The person's genetic architecture has been a well-established risk factor for RDs, albeit to variable degrees. Patients with early-onset diseases and/or positive family history have a strong genetic component, while patients with late-onset RDs demonstrate a more complex interplay of genetic and environmental risk factors...
