Systemic lupus erythematosus (SLE) is a chronic autoimmune inflammatory disease and currently has no effective therapy. The genome-wide analyses indicate that interleukin-1 receptor associated kinase 1 (IRAK1) is associated with the susceptibility of SLE in humans. In the present study, we identified that IRAK1 was overexpressed and hyper-activated in splenic mononuclear cells from B6.MRL-Fas(lpr)/Nju (B6.lpr) mice and peripheral blood mononuclear cells (PBMCs) from SLE patients. Intraperitoneal treatment with a small molecular inhibitor of IRAK1 (IRAK1/4 inhibitor or IRAK-Inh) significantly mitigated inflammatory responses and renal injury in B6...

Aberrant CD11a overexpression in CD4+ T cells induces T cell auto-reactivity, which is an important factor for systemic lupus erythematosus (SLE) pathogenesis. Although many studies have focused on CD11a epigenetic regulation, little is known about histone methylation. JMJD3, as a histone demethylase, is capable of specifically removing the trimethyl group from the H3K27 lysine residue, triggering target gene activation. Here, we examined the expression and function of JMJD3 in CD4+ T cells from SLE patients...

Systemic lupus erythematosus (SLE) is a multisystem autoimmune disorder punctuated by varied multiorgan complications all along the course of its natural history. Lymphoma represents a relatively well-recognized malignant phenomenon associated with lupus. The cause and effect relationships of lymphoma in SLE have been subject to extensive scrutiny with several studies reporting on clinic-pathologic characteristics and risk factors predicting lymphoma development in SLE. However, the pathogenic role of immunosuppressives in SLE-related lymphoma still remains unclear, and indices to help guide diagnosis, prognostication, therapy, and posttreatment monitoring are yet to be established...

Deimination, a posttranslational modification of arginine to citrulline carried out by peptidylarginine deiminases, may compromise tolerance of self-antigens. Patients with connective tissue autoimmunity, particularly rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), or Felty's syndrome, present with autoantibodies to deiminated histones (dH), which thus form a category of antibodies to citrullinated protein antigens (ACPA). In general, ACPA are a sensitive diagnostic for RA and may form in response to the release of nuclear chromatin (DNA plus dH) from granulocytes, usually referred to as neutrophil extracellular traps...

Despite increasing evidence that long non-coding RNAs (lncRNAs) widely take part in human diseases, the role of lncRNAs in systemic lupus erythematosus (SLE) is largely unknown. In this study, we performed a two-stage study to explore the plasma levels of five lncRNAs (GAS5, linc0949, linc0597, HOTAIRM1 and lnc-DC) and their potential as SLE biomarkers. Compared with healthy controls, plasma levels of GAS5 and lnc-DC were significantly decreased (P < 0.001 and P = 0.002, respectively) while linc0597 were overexpressed in SLE patients (P < 0...

The immune system provides protection to tissues damaged by infectious microrganisms or physical damage. In autoimmune diseases, the immune system recognizes and attacks its own tissues i.e., self-destruction. Various agents such as genetic factors and environmental triggers are thought to play a major role in the development of autoimmune diseases. A common feature of all autoimmune diseases is the presence of autoantibodies and inflammation, including mononuclear phagocytes, autoreactive T lymphocytes and autoantibody producing B cells (plasma cells)...

Scabies is a commonly occurring infectious immune-mediated inflammatory skin disease. Immune-mediated inflammatory processes are also observed in autoimmune diseases. There have been very few previous studies; however, that have investigated the possible association between scabies and autoimmune diseases. To address this research gap, we conducted a nationwide population-based cohort study that included a total of 4481 scabies patients and 16,559 control subjects matched by gender, age, insured region, urbanization and income...

Type I interferons (IFNs) are essential mediators of antiviral responses. These cytokines have been implicated in the pathogenesis of autoimmunity, most notably systemic lupus erythematosus (SLE), diabetes mellitus, and dermatomyositis, as well as monogenic type I interferonopathies. Despite a fundamental role in health and disease, the direct quantification of type I IFNs has been challenging. Using single-molecule array (Simoa) digital ELISA technology, we recorded attomolar concentrations of IFNα in healthy donors, viral infection, and complex and monogenic interferonopathies...

Background Cathelicidin (LL-37), an endogenous antimicrobial peptide, has recently been involved in the pathogenesis of autoimmune diseases. To assess whether LL-37 reflects disease activity, we measured serum levels of it in systemic lupus erythematosus (SLE) patients with active and inactive disease compared to healthy controls. LL-37 was also compared between new and old cases. Moreover, the correlation of LL-37 and pro-oxidant, antioxidant balance (PAB) was measured. Methods The study population consisted of 50 SLE patients and 28 healthy controls...

Objectives Childhood-onset systemic lupus erythematosus (cSLE) is a multisystemic autoimmune disease characterized by inflammatory organ damage by means of vasculitis. Pentraxin-3 (PTX3) is expressed locally at the sites of inflammatory processes, predominantly from endothelial cells. In adult studies, PTX3 has shown to be an indicator of active vasculitis both in large-vessel and small-vessel vasculitides, as well as in SLE. Moreover, in SLE it has found to be correlated with disease activity, and with some of the clinical manifestations and laboratory parameters...
