Juvenile systemic lupus erythematosus (JSLE) is a multi-system autoimmune inflammatory disease. Generally, 60% of patients will develop lupus nephritis (LN); thus, early recognition and treatment is associated with better outcome. Interleukin 22 (IL-22) is involved in tissue inflammation and is regulated by interleukin 22 binding protein (IL-22BP). This study aimed to use IL-22BP as a non-invasive marker for disease activity in JSLE and LN. This is a cross-sectional study conducted on 82 subjects: 51 JSLE patients and 31 healthy controls of matched age and gender...

The IL-23/IL-17 pathway is important in multiple autoimmune diseases, but its effect on lupus pathology remains unclear, with opposing trials in murine models of the disease. In this study, we show a disease activity-related upregulation of serum IL-23 and IL-23 receptor in patients with systemic lupus erythematosus (SLE) as compared with healthy controls. When added in SLE T cell in vitro cultures, IL-23 induced IL-17 and limited IL-2 production, whereas T follicular helper and double negative (DN) T cells significantly expanded...

BACKGROUND: Interferon (IFN)-α is thought to have a pivotal role in systemic lupus erythematosus (SLE), and type III IFNs (IFN-λ) were recently also associated with SLE. In this study, we measured levels of IFN-α, IFN-λ1, and related cytokines, such as IL-17A, IL-23, and interferon-γ-induced protein 10 (IP-10), in a Karolinska University Hospital cohort of patients with SLE and control subjects. The objective of the study was to investigate if cytokine measurements could identify different subsets of patients with active SLE and higher disease damage...

T-follicular helper (Tfh) cells are a specialized subset of T cells that provide help to B cells and promote the formation of germinal centers (GCs). Tfh cells transmit important signals to B cells that drive class switch recombination, somatic hyper-mutation, the generation of high-affinity antibodies, immunological memory and their differentiation into plasma cells or memory B cells in the GCs. Tfh-cell differentiation is regulated by the coordinated functions of distinct cytokines, including interleukin (IL)-6, IL-21, IL-12, IL-23, IL-2, IL-7 and transforming growth factor-β (TGF-β), as well as transcription factors, including B-cell lymphoma 6 protein (Bcl-6), Signal transducers and activators of transcription (STAT)1, STAT3, STAT4, B-cell activating transcription factor (Batf), interferon regulatory factor 4 (IRF4), v-maf avian musculoaponeurotic fibrosarcoma oncogene homolog (C-Maf), T-cell-specific transcription factor 1 (TCF-1) and Achaete-scute homolog 2 (Acl2), which have been shown to form a complex transcriptional network...

Probiotics are commensal or nonpathogenic microbes that colonize the gastrointestinal tract and confer beneficial effects on the host through several mechanisms such as competitive exclusion, anti-bacterial effects, and modulation of immune responses. There is growing evidence supporting the immunomodulatory ability of some probiotics. Several experimental and clinical studies have been shown beneficial effect of some probiotic bacteria, particularly Lactobacillus and Bifidobacteria strains, on inflammatory and autoimmune diseases...

We evaluated plasma IL-10, IFN-alpha, IL-23, IFN-gamma, IP-10, MCP-1, 8-OHdG, leukocyte mtDNA, serum anti-dsDNA antibodies and disease activity index (SLEDAI) in SLE patients. 93 patients (35 nephritis, 4 under dialysis, 5 under rituximab) and 50 healthy controls were recruited. Compared with healthy controls, SLE patients had higher IL-10, IFN-alpha, IL-23, IFN-gamma, IP-10 and MCP-1 (p<0.05). High IFN-alpha (p=0.031) and IP-10 (p=0.026) correlated with high SLEDAI; high IFN-alpha (p<0.001), IL-23 (p=0...

Interleukin-12 family cytokines have emerged as critical regulators of immunity with some members (IL-12, IL-23) associated with disease pathogenesis while others (IL-27, IL-35) mitigate autoimmune diseases. Each IL-12 family member is comprised of an α and a β chain, and chain-sharing is a key feature. Although four bona fide members have thus far been described, promiscuous chain-pairing between alpha (IL-23p19, IL-27p28, IL-12/IL-35p35) and beta (IL-12/IL-23p40, IL-27/IL-35Ebi3) subunits, predicts six possible heterodimeric IL-12 family cytokines...

Inflammation instigated by interleukin (IL)-17-producing cells is central to the development and pathogenesis of several human autoimmune diseases and animal models of autoimmunity. The expansion of IL-17-producing cells from healthy donors is reportedly promoted by mesenchymal stem cells derived from fetal bone marrow. In the present study, human umbilical cord-derived mesenchymal stem cells (hUC-MSCs) were examined for their effects on lymphocytes from healthy donors and from patients with systemic lupus erythematosus (SLE)...

Th1 and Th17 cells have been strongly implicated in the pathogenesis of systemic lupus erythematosus (SLE). Interleukin (IL)-12 and IL-23 respectively drive the polarization of Th1 and Th17 cells and share a common p40 subunit. In this study, the protective and therapeutic effects of a truncated human IL-12rβ1 receptor (tIL12rβ1) targeting IL-12/IL-23 p40 were evaluated in chronic graft-versus-host disease (cGVHD)-induced SLE-like model. The results indicated that tIL12rβ1 treatment effectively delayed the proteinuria onset and induced a significant remission of proteinuria, autoantibody production, and immune complex deposition in the mouse model...

OBJECTIVES: Patients with systemic lupus erythematosus (SLE) and primary Sjögren's syndrome (pSS) have increased IL-1β levels. IL-1β and other pro-inflammatory cytokines have a modulating activity on cardiac ion channels and have been associated with increased arrhythmic risk in rheumatoid arthritis patients. Likewise, adult patients with connective tissue diseases (CTDs) may have prolonged QTc intervals associated with the presence of anti-Ro/SSA antibodies. Our objective was to evaluate the presence of serum IL-1β in subjects with CTDs, in relation to the presence of anti-Ro/SSA antibodies and QTc interval duration...

BACKGROUND: Systemic lupus erythematosus (SLE) is a multisystem autoimmune disease. Emerging data suggests that T helper 17 (Th17) cells play a pathogenic role in SLE and the increased number of these cells correlates with disease activity. In recent years, 1α, 25-dihydroxyvitamin D3 (1,25VitD3) has been considered as an immunomodulatory factor. OBJECTIVE: To investigate the effect of 1,25VitD3 on Th17 cells and on the expression of related cytokines in SLE patients...

Th17 cells are a discrete subset of T cell subpopulation, which produce IL-17 and certain other pro-inflammatory cytokines. A regulatory role of Th17 cells have been proposed in several autoimmune diseases including psoriasis, psoriatic arthritis (PsA), ankylosing spondylitis (AS), rheumatoid arthritis, inflammatory bowel disease, systemic lupus erythematosus, and multiple sclerosis. Psoriatic disease is an autoimmune disease which mainly involves skin and joints. Until recently, psoriasis and PsA were thought to be Th1 mediated disease, but after the discovery of IL-17 and IL-17 knockout animal studies as well as human experimental data indicate a crucial role of the Th17 cells in the pathogenesis of psoriasis and PsA...

PURPOSE OF REVIEW: Interleukin (IL)-23 and the related cytokine IL-17 play vital roles in immune-mediated inflammatory pathology. In the years since its discovery, IL-23 has been implicated as a central pathogenic factor in multiple rheumatic conditions and has been shown to act via a wide range of immune cells including type 17 T-helper (Th17) cells and innate-like immune cells. We review here the pivotal role of these cytokines and IL-23-responsive cells in both the bona fide autoimmune rheumatic diseases rheumatoid arthritis and systemic lupus erythematosus, as well as the spondyloarthropathies which more closely resemble the auto-inflammatory conditions...

Making a correct diagnosis is pivotal in the practice of clinical rheumatology. Occasionally, the consultation fails to provide desired clarity in making labeling an individual as having fibromyalgia (FM), systemic lupus erythematosus (SLE) or rheumatoid arthritis (RA). A chemokine and cytokine multiplex assay was developed and tested with the goal of improving and achieving an accurate differential diagnosis. 160 patients with FM, 98 with RA and 100 with SLE fulfilling accepted criteria were recruited and compared to 119 controls...
