B lymphocyte hyperactivity in systemic lupus erythematosus (SLE) is T cell-dependent, and CD4(+) T cell activation is essential to SLE pathogenesis. However, the mechanism of the deregulation of CD4(+) T cells in SLE is largely unknown. T-cell immunoglobulin and ITIM domain (TIGIT) is a new inhibitory receptor preferentially expressed on activated CD4(+) T cells. Here, we addressed the role of TIGIT in the pathogenesis of SLE. Our results showed that TIGIT expression on CD4(+) T cells was significantly elevated in patients with SLE and highly correlated with the activity of the disease...

We recently identified ten novel SLE susceptibility loci in Asians and uncovered several additional suggestive loci requiring further validation. This study aimed to replicate five of these suggestive loci in a Han Chinese cohort from Hong Kong, followed by meta-analysis (11,656 cases and 23,968 controls) on previously reported Asian and European populations, and perform bioinformatic analyses on all 82 reported SLE loci to identify shared regulatory signatures. We performed a battery of analyses for these five loci, as well as joint analyses on all 82 SLE loci...

We reported a rare case of topical 5-aminolevulinic acid (ALA)-photodynamic therapy (PDT) in the treatment of a systemic lupus erythematosus (SLE) patient with lower limb multiple Bowen's disease (BD). At the end of the treatment, an excellent clinical response was observed and no recurrence of rash after 2 months of treatment. The recovery time was prolonged only after the first treatment, however, no photosensitive phenomena were observed during and after the treatment. This is the first report to describe ALA-PDT for patient-confirmed photosensitivity in an Asian patient...

Psychological effects related to systemic lupus erythematosus (SLE) are tremendous. While a variety of psychological treatments have been applied to assist SLE patients, the effects of mindfulness practice were never documented in SLE. Mindfulness-based psychotherapy includes several techniques, including body-scan, breathing exercises, and full awareness during daily activities. In this case report, we present a first attempt at conducting mindfulness-based group therapy among SLE patients. Six female SLE patients participated in an 8-week program...

The aberrant generation or activation of T follicular helper (Tfh) cells contributes to the pathogenesis of systemic lupus erythematosus (SLE), yet little is known about how these cells are regulated. In this study, we demonstrated that the frequency of Tfh cells was increased in lupus-prone B6.MRL-<em>Fas<sup>lpr</sup></em> (B6.<em>lpr</em>) mice and positively correlated to plasma cell proportions and serum total IgG as well as anti-dsDNA antibody levels. Transplantation of human umbilical cord mesenchymal stem cells (UC-MSCs) ameliorated lupus symptoms in B6...

Patients presenting with bone marrow fibrosis not accompanied by well-established autoimmune diseases, such as systemic lupus erythematosus, or malignant diseases, are considered to have primary autoimmune myelofibrosis (AIMF). Primary AIMF has been reported to follow a benign course and responds well to treatment with immunosuppressive agents. Immune thrombocytopenia (ITP) is also an autoimmune disorder characterized by antiplatelet-antibody-mediated thrombocytopenia in the absence of other causes of thrombocytopenia...

Interest in cell-derived extracellular vesicles and their physiological and pathological implications is constantly growing. Microvesicles, also known as microparticles, are small extracellular vesicles released by cells in response to activation or apoptosis. Among the different microvesicles present in the blood of healthy individuals, platelet-derived microvesicles (PMVs) are the most abundant. Their characterization has revealed a heterogeneous cargo that includes a set of adhesion molecules. Similarly to platelets, PMVs are also involved in thrombosis through support of the coagulation cascade...

This study aims to determine whether uric acid levels contribute to new renal damage in systemic lupus erythematosus (SLE) patients. This prospective study was conducted in consecutive patients seen since 2012. Patients had a baseline visit and follow-up visits every 6 months. Patients with ≥2 visits were included; those with end-stage renal disease (regardless of dialysis or transplantation) were excluded. Renal damage was ascertained using the SLICC/ACR damage index (SDI). Univariable and multivariable Cox-regression models were performed to determine the risk of new renal damage...

(5R)-5-Hydroxytriptolide (LLDT-8), a triptolide derivative with low toxicity, was previously reported to have strong immunosuppressive effects both in vitro and in vivo, but it remains unknown whether LLDT-8 has a therapy effect on systemic lupus erythematosus. In this study, we aimed to investigate the therapeutic effects of LLDT-8 on lupus nephritis in MRL/lpr mice, a model of systemic lupus erythematosus. Compared with vehicle group, different clinical parameters were improved upon LLDT-8 treatment: prolonged life-span of mice, decreased proteinuria, downregulated blood urea nitrogen and serum creatinine, reduced glomerular IgG deposits, and ameliorated histopathology...

Galectin-1 is an endogenous immunoregulatory lectin-type protein. Its most important effects are the inhibition of the differentiation and cytokine production of Th1 and Th17 cells, and the induction of apoptosis of activated T-cells. Galectin-1 has been identified as a key molecule in antitumor immune surveillance, and data are accumulating about the pathogenic role of its deficiency, and the beneficial effects of its administration in various autoimmune disease models. Initial animal and human studies strongly suggest deficiencies in both galectin-1 production and responsiveness in systemic lupus erythematosus (SLE) T-cells...

Autophagy is associated with various immune diseases, including systemic lupus erythematosus (SLE). Seven variants within autophagy-related genes previously reported to show top association signals by genome-wide association studies in immune diseases were selected for analysis. Initially, 510 SLE patients (631 controls) were enrolled in the study. An additional independent cohort of 511 SLE patients (687 controls) was included for replication. Polymorphism rs2638272 in LRRK2 gene showed significant association with susceptibility to SLE (P = 1...

A hallmark of autoimmunity in murine models of lupus is the formation of germinal centers (GCs) in lymphoid tissues where self-reactive B cells expand and differentiate. In the host response to foreign antigens, follicular dendritic cells (FDCs) maintain GCs through the uptake and cycling of complement-opsonized immune complexes. Here, we examined whether FDCs retain self-antigens and the impact of this process in autoantibody secretion in lupus. We found that FDCs took up and retained self-immune complexes composed of ribonucleotide proteins, autoantibody, and complement...

Hydroxychloroquine is the cornerstone of medical therapy in systemic lupus erythematosus (SLE). We report a case of erythema multiforme in association with this medication in a 25-year-old white woman with SLE. We provide a detailed review of the reported cases in the literature of hydroxychloroquine-induced severe cutaneous adverse reactions. To our knowledge, this is the first reported case of hydroxychloroquine-induced erythema multiforme in the setting of SLE.

Systemic lupus erythematosus (SLE) is a systemic autoimmune disease with multiple etiological factors. Mannose-binding lectin (MBL) plays a key role in innate immunity by activating antibody-independent lectin complement pathway, opsonisation, phagocytosis, and immune complex (IC) clearance. Genetic polymorphisms in the promoter and coding regions of MBL gene affect the circulatory levels and biological activity of MBL. Defects in MBL can lead to defective opsonisation and, hence, hamper clearance of apoptotic debris, the persistence of which can drive autoantibody formation in lupus...

Similar to patients with other rheumatic diseases, patients with systemic lupus erythematosus (SLE) nowadays can also have the desire to terminate immunosuppressive and immunomodulatory medications. In order to provide appropriate advice to patients, the two main issues are the risk of severe adverse events under long-term therapy with any drug and the perceived risk of a flare, in particular of severe flares. The risks of long-term therapy vary greatly between drugs, ranging from severe unacceptable risks with cyclophosphamide and higher dose glucocorticoids to low risks usually outweighed by long-term benefits with hydroxychloroquine...

Amino acid replacement mutations in certain CLL stereotyped B-cell receptor (BCR) immunoglobulins (IGs) at defined positions within antigen-binding sites strongly imply antigen selection. Prime examples of this are CLL subset 4 BCR IGs using IGHV4-34/IGHD5-18/IGHJ6 and IGKV2-30/IGKJ2 rearrangements. Conspicuously and unlike most CLL IGs, subset 4 IGs do not bind apoptotic cells. By testing the (auto)antigenic reactivities of subset 4 IGs toward viable lymphoid-lineage cells and specific autoantigens typically bound by IGHV4-34(+) IGs, we found IGs from both subset 4 and non-subset 4 IGHV4-34-expressing CLL cases bind naïve B cells...

A SNP identified as rs548234, which is found in PRDM1, the gene that encodes BLIMP1, is a risk allele associated with systemic lupus erythematosus (SLE). BLIMP1 expression was reported to be decreased in women with the PRDM1 rs548234 risk allele compared with women with the nonrisk allele in monocyte-derived DCs (MO-DCs). In this study, we demonstrate that BLIMP1 expression is regulated by the binding of Kruppel-like factor 4 (KLF4) to the risk SNP. KLF4 is highly expressed in MO-DCs but undetectable in B cells, consistent with the lack of altered expression of BLIMP1 in B cells from risk SNP carriers...
