Several different theories of schizophrenia (SCZ) were discussed; the causes of this disease are not yet clear. Using ELISA, it was shown that titers of autoantibodies against myelin basic protein (MBP) in SCZ patients are ~1.8-fold higher than in healthy individuals but 5.0-fold lower than in patients with multiple sclerosis. Several rigid criteria were checked to show that the MBP-hydrolyzing activity is an intrinsic property of SCZ IgGs. Approximately 82% electrophoretically homogeneous SCZ IgGs purified using several affinity sorbents including Sepharose with immobilized MBP hydrolyze specifically only MBP but not many other tested proteins...

PURPOSE OF REVIEW: Lupus nephritis is a frequent complication of systemic lupus erythematosus and is more common and severe in children. This is a disease of the immune system characterized by T cell, B cell, and complement activation, as well as immune complex formation and deposition. The introduction of steroids and later cyclophosphamide transformed lupus nephritis from a fatal to a treatable condition. However, the standard therapies currently used for treatment carry significant toxicity and chronic kidney disease still remains a far too frequent outcome...

Patients with systemic lupus erythematosus (SLE) have a tremendously increased risk for cardiovascular disease (CVD), which could not be accounted in entirety by traditional Framingham risk factors. To study whether the accelerated atherosclerosis in SLE patients is mediated by type I interferon (IFN-I) through the regulation of endothelial progenitor cells (EPCs), we created a line of C57BL/6 mice with deficiency in both apolipoprotein E (ApoE-/-) and fas ligand (FasL-/-, gld.). As expected, the resultant gld...

Background: Accumulating evidence indicates that microRNAs play a pivotal role in the pathogenesis of systemic lupus erythematosus (SLE). This study tested the hypothesis that microRNA is associated with the mitochondrial apoptotic pathway in patients with SLE. Methods: Thirteen patients were in the clinical comparison study and microRNA study and overall 19 patients in the study of intracellular protein. Levels of microRNAs were determined by miRNeasy kit in 13 patients with SLE and 29 volunteer normal controls...

Mouse p202 is a disease locus for lupus and a dominant-negative inhibitor of AIM2 inflammasome activation. A human homolog of p202 has not been identified so far. Here, we report a novel transcript isoform of human IFI16-designated IFI16-β, which has a domain architecture similar to that of mouse p202. Like p202, IFI16-β contains two HIN domains, but lacks the pyrin domain. IFI16-β is ubiquitously expressed in various human tissues and cells. Its mRNA levels are also elevated in leukocytes of patients with lupus, virus-infected cells, and cells treated with interferon-β or phorbol ester...

REVIEW
Anselm Mak
Over the past two decades it has been increasingly recognized that vitamin D, aside from its crucial involvement in calcium and phosphate homeostasis and the dynamics of the musculoskeletal system, exerts its influential impact on the immune system. The mechanistic roles that vitamin D plays regarding immune activation for combating infection, as well as pathologically and mediating autoimmune conditions, have been progressively unraveled. In vitro and in vivo models have demonstrated that the action of vitamin D on various immunocytes is not unidirectional...

INTRODUCTION:  Systemic lupus erythematodes (SLE) represents an autoimmune disease with a highly variable clinical course affecting numerous organs. Hepatic manifestation seems to be rare. It is not clear whether hepatic disease in SLE is of any prognostic importance or whether it correlates with disease activity. METHODS:  Our patient cohort included 172 patients with proven SLE, all treated at Bogenhausen Hospital between 01.2009 and 12.2015. Retrospectively, all admissions as inpatients and outpatients were analyzed (n = 671; mean 3...

BACKGROUND: Adipokines are chemical mediators released from adipose tissue involved in regulation of appetite, insulin sensitivity, immune system and inflammatory responses. Adipokines contributes to low grade inflammatory response in autoimmune disease like Systemic Lupus Erythematosus (SLE) but the pathophysiology is yet not clear. The aim of this study is to understand role of adipokine interactions in SLE disease pathogenesis. METHODS: Sixty newly diagnosed treatment naïve SLE patients fulfilling the ACR criteria and forty age-sex matched healthy subjects were enrolled in thiscase-control study...

Takayasu arteritis (TA) is a large vessel vasculitis of unknown pathogenesis. Assessment of disease activity is a challenge and there is an unmet need for relevant biomarker(s). In our previous study, NMR based serum metabolomics had revealed distinctive metabolic signatures in TA patients compared with age/sex matched healthy controls and Systemic Lupus Erythematosus (SLE). In this study, we investigate whether the metabolites correlate with disease activity. Patients with TA fulfilling American College of Rheumatology (ACR) criteria were enrolled and disease activity was assessed using Indian Takayasu Clinical Activity Score using Acute Phase Reactant - Erythrocyte Sedimentation Rate [ITAS-A (ESR]...

SLE is a complex autoimmune disease that results from the interplay of genetics, epigenetics and environmental exposures. DNA methylation is an epigenetic mechanism that regulates gene expression and tissue differentiation. Among all the epigenetic modifications, DNA methylation perturbations have been the most widely studied in SLE. It mediates processes relevant to SLE, including lymphocyte development, X-chromosome inactivation and the suppression of endogenous retroviruses. The establishment of most DNA methylation marks occurs in utero; however, a small percentage of epigenetic marks are dynamic and can change throughout a person's lifetime and in relation to exposures...

Objectives: Cardiovascular diseaseand heart failure (CHF) are leading causes of death in systemic lupus erythematosus (SLE). The underlying mechanisms for increased CHF in SLE are unclear but myocardial inflammation and lupus myocarditis (LM) may play a role. We propose that 18 F-fluorodeoxyglucose-positron emission tomography (18 F-FDG-PET)/CT can help diagnose LM. Methods: This report describes eight patients with presumed LM; five patients were evaluated due to active cardiorespiratory symptoms and three patients were participating in a pilot study to determine the prevalence of subclinical myocarditis in SLE...
