  The importance of cellular metabolism has long been known as Warburg effect; cancer cells are characterized by mitochondrial defect that shifts towards aerobic glycolysis. Recently, many reports have revealed that immune metabolism is a key factor for controlling immune cell proliferation and differentiation. Resting lymphocytes generate energy through oxidative phosphorylation and fatty acid oxidation, whereas activated lymphocytes rapidly shift to glycolysis. Especially in T cells, more precise mechanism of regulating metabolism have been clarified on differentiation from naïve T cells to effector T cells...

Systemic lupus erythematosus (SLE) is a chronic autoimmune inflammatory disease which follows a relapsing and remitting course that can manifest in any organ system. While classic manifestations consist of arthralgia, myalgia, frank arthritis, a malar rash and renal failure to name a few, cardiac tamponade, however, is a far less common and far more dangerous presentation. We highlight the case of a 61year-old male with complaints of acute onset shortness of breath and generalized body aches associated with a fever and chills in the ER...

Systemic lupus erythematosus (SLE) is characterized by a multifaceted pathogenesis and a heterogeneous clinical expression. The kidney involvement is almost unavoidable in all forms of SLE with chronic evolution, 75% of patients developing renal lesions defined as lupus nephritis (LN) - a glomerulonephritis with an extremely diverse lesion spectrum. The present study aimed to reevaluate a series of cases diagnosed as LN, focusing on the histological features in correlation with the level of activity and chronicity...

Ju-Yang Jung, Chang-Hee Suh
Systemic lupus erythematosus (SLE) is a chronic autoimmune disease with diverse manifestations, and its pathogenesis is unclear and complicated. Infection and SLE are similar in that they both cause inf lammatory reactions in the immune system; however, one functions to protect the body, whereas the other is activated to damage the body. Infection is known as one of the common trigger factors for SLE; there are a number of reports on infectious agents that provoke autoimmune response. Several viruses, bacteria, and protozoa were revealed to cause immune dysfunction by molecular mimicry, epitope spreading, and bystander activation...

Systemic lupus erythematosus (lupus, SLE) is a chronic autoimmune disease characterized by the production of autoantibodies, which bind to antigens and are deposited within tissues to fix complement, resulting in widespread systemic inflammation. The studies presented herein are consistent with hyperpolarized, adenosine triphosphate (ATP)-deficient mitochondria being central to the disease process. These hyperpolarized mitochondria resist the depolarization required for activation-induced apoptosis. The mitochondrial ATP deficits add to this resistance to apoptosis and also reduce the macrophage energy that is needed to clear apoptotic bodies...

OBJECTIVE: We have previously established that NCF2 (Neutrophil cytosolic factor 2) is a lupus predisposing gene and identified lupus patients with point mutations that are predicted to cause reduced NADPH oxidase activity. This study was undertaken to investigate the relationship between reduced leukocyte NADPH oxidase activity and immune dysregulation associated with SLE. METHODS: We generated NCF2-null mice, in which NADPH oxidase activity is absent, on the non-autoimmune C57BL/6 background and on the NZM...

Lupus nephritis is a leading cause of mortality among systemic lupus erythematosus (SLE) patients, and its heterogeneous nature poses a significant challenge to the development of effective diagnostics and treatments. Single cell RNA sequencing (scRNA-seq) offers a potential solution to dissect the heterogeneity of the disease and enables the study of similar cell types distant from the site of renal injury to identify novel biomarkers. We applied scRNA-seq to human renal and skin biopsy tissues and demonstrated that scRNA-seq can be performed on samples obtained during routine care...

Systemic lupus erythematosus (SLE) is a chronic disease that considerably hampers patient's daily living. Qualitative studies with patients' interviews have been conducted to describe the experiences and perspectives of adults living with SLE. Among existing generic and disease-specific quality of life (QOL) questionnaires, none succeeded to exhaustively measure patient's preoccupations. However, these tools are useful to quantify the burden of the disease. Social precariousness, socioeconomic status and education level are intimately correlated to QOL measures, either generic or disease-specific...

Systemic Lupus Erythematosus (SLE) is a clinically heterogeneous chronic, inflammatory autoimmune disorder that affects multiple organs where exact etiology of the disease is not yet clearly understood. Various evidences suggest that genetic polymorphisms in inflammatory mediators like cytokines and chemokines may influence development of the disease. Here, we investigated whether functional polymorphism at the Monocyte Chemoattractant Protein-1 (MCP-1) regulatory region associates with disease phenotype in Indian SLE patients...

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...

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)...

Nova Scotia Duck Tolling Retrievers (NSDTRs) are a dog breed often affected by immune-mediated rheumatic disease (IMRD), a disorder characterised by chronic stiffness and joint pain. Most, but not all, dogs with IMRD, have antinuclear antibodies (ANA), which are also commonly present in the autoimmune disease systemic lupus erythematosus (SLE). The clinical and diagnostic findings of IMRD indicate that it is an SLE-related disorder. C-reactive protein (CRP), an acute phase protein, is a quantitative marker of inflammation for many diseases and is used for diagnosing and monitoring systemic inflammation in both humans and dogs...
