RATIONALE: Systemic lupus erythematosus (SLE) is a complex autoimmune disease characterized by autoantibody production, complement activation, and deposition of immune complexes in tissues and organs. SLE can involve any region of the visual system. Although ocular manifestations are not part of the classification criteria for SLE, they can be observed in up to one-third of the patients with SLE. They are rarely reported at the time of disease onset. Retinal vasculitis is usually associated with active generalized disease...

BACKGROUND Systemic lupus erythematosus (SLE) is a multisystem autoimmune disorder of unknown etiology which can present at any age with symptoms of mucocutaneous, musculoskeletal, renal, central nervous system, and nonspecific clinical pictures making the disease a "master of mimicry". CASE REPORT A 53-year-old female, who was recently diagnosed with SLE, presented with right-sided sharp and electric shock-like facial pain starting at the side of her right nostril and traveling down the naso-labial fold and then back to the angle of the jaw, mostly in the region of V2-V3 distribution with no radiation beyond trigeminal distribution...

OBJECTIVE: Effector CD8+ T cell function is impaired in SLE and associated with compromised ability to fight infections. SLAMF7 engagement has been shown to enhance NK cell degranulation. Thus, we characterized the expression and function of SLAMF7 on CD8+ T cells subsets isolated from peripheral blood of SLE patients and healthy subjects. METHODS: CD8+ T cell subset distribution, SLAMF7 expression and cytolytic enzyme expression (perforin, GzmA, GzmB) were monitored on cells isolated from SLE patients and healthy controls by flow cytometry...

Dysfunctional polymorphisms of FcγRIIb, an inhibitory receptor, are associated with Systemic Lupus Erythaematosus (SLE). Cryptococcosis is an invasive fungal infection in SLE, perhaps due to the de novo immune defect. We investigated cryptococcosis in the FcγRIIb-/- mouse-lupus-model. Mortality, after intravenous C. neoformans-induced cryptococcosis, in young (8-week-old) and older (24-week-old) FcγRIIb-/- mice, was higher than in age-matched wild-types. Severe cryptococcosis in the FcγRIIb-/- mice was demonstrated by high fungal burdens in the internal organs with histological cryptococcoma-like lesions and high levels of TNF-α and IL-6, but not IL-10...

Systemic lupus erythematosus (SLE) is a multi-organ disease of unknown etiology in which the normal immune responses are directed against the body's own healthy tissues. Patients with SLE often suffer from chronic pain. Currently, no animal studies have been reported about the mechanisms underlying pain in SLE. In this study, the development of chronic pain in MRL lupus-prone (MRL/lpr) mice, a well-established lupus mouse model, was characterized for the first time. We found that female MRL/lpr mice developed thermal hyperalgesia at the age of 13 weeks, and mechanical allodynia at the age of 16 weeks...

Vascular-targeted carriers (VTCs) are designed as leukocyte mimics, decorated with ligands that target leukocyte adhesion molecules (LAMs) and facilitate adhesion to diseased endothelium. VTCs require different design considerations than other targeted particle therapies; adhesion of VTCs in regions with dynamic blood flow requires multiple ligand-receptor (LR) pairs that provide particle adhesion and disease specificity. Despite the ultimate goal of leukocyte mimicry, the specificity of multiple LAM-targeted VTCs remains poorly understood, especially in physiological environments...

PURPOSE: Systemic lupus erythematosus (SLE) is a chronic inflammatory female-predominant autoimmune disease that can affect the central nervous system and exhibit neuropsychiatric symptoms. In SLE patients without neuropsychiatric symptoms (non-NPSLE), recent diffusion tensor imaging studies showed white matter abnormalities in their brains. The present study investigated the entire brain white matter structural connectivity in non-NPSLE patients by using probabilistic tractography and connectivity-based analyses...

OBJECTIVE: Systemic lupus erythematosus (SLE) is an autoimmune disease characterized by extensive immune response including over-activation of T and B cells development of pathogenic autoantibodies, organ damage induced by the formation and deposition of immune complex, and the abnormal elevation of type I interferon. Semaphorin5A (Sema5A), is essentially involved in immune cell regulation and also implicated in the pathogenesis of autoimmune disorders. We aimed to evaluate the role of Sema5A in patients with SLE...

Studies attempting to functionally interpret complex-disease susceptibility loci by GWAS and eQTL integration have predominantly employed microarrays to quantify gene-expression. RNA-Seq has the potential to discover a more comprehensive set of eQTLs and illuminate the underlying molecular consequence. We examine the functional outcome of 39 variants associated with Systemic Lupus Erythematosus (SLE) through integration of GWAS and eQTL data from the TwinsUK microarray and RNA-Seq cohort in lymphoblastoid cell lines...

Type I interferons (IFN-α/β)-inducible PYRIN and HIN domain-containing protein family includes Absent in Melanoma 2 (murine Aim2 and human AIM2), murine p202, and human PYRIN-only protein 3 (POP3). The generation of Aim2-deficient mice indicated that the Aim2 protein is essential for inflammasome activation, resulting in the secretion of interleukin-1β (IL-1β) and IL-18 and cell death by pyroptosis. Further, Aim2-deficiency also increased constitutive expression of the IFN-β and expression of the p202 protein...

The dentate gyrus (DG) as part of the hippocampal formation is believed to serve as a gatekeeper with strong inhibitory properties against uncontrolled propagation of neuronal activity from the entorhinal cortex and neocortical structures. In temporal lobe epilepsy, the DG becomes hyperexcitable and loses its gate function, enabling propagation of ictal activity into downstream structures such as CA3 and CA1 areas. Furthermore, the DG, apart from facilitating propagation, may also be able to autonomously generate ictal activity, but this point has remained open so far...

The nonstructural protein NS1 of human parvovirus B19 (B19) is known to exacerbate disease activity in systemic lupus erythematosus (SLE). However, no specific medicine for B19 infection is available. The roots of Gentiana macrophylla Pall. (GM), the traditional Chinese medicine "Qinjiao," have been used for centuries to treat rheumatic disease, including SLE. Herein, we aimed to investigate the effects of GM root extract (100 and 300 mg/kg body weight) on B19-NS1-exacerbated liver injury in NZB/W F1 mice; liver tissues were assessed by hematoxylin-eosin staining and immunoblotting...

Introduction Systemic lupus erythematosus (SLE) leads to a range of biopsychosocial health outcomes through an unpredictable and complex disease path. The LupusPRO is a comprehensive, self-report measure developed specifically for populations with SLE, which assesses both health-related quality of life and non-health related quality of life. Given its increasingly widespread use, additional research is needed to evaluate the psychometric integrity of the LupusPRO across diverse populations. The objectives of this study were to evaluate the performance of the LupusPRO in two divergent patient samples and the model fit between both samples...

Autoimmune/inflammatory syndrome induced by adjuvants (ASIA) has been widely described in many studies conducted thus far. The syndrome incorporates five immune-mediated conditions, all associated with previous exposure to various agents such as vaccines, silicone implants and several others. The emergence of ASIA syndrome is associated with individual genetic predisposition, for instance those carrying HLA-DRB1*01 or HLA-DRB4 and results from exposure to external or endogenous factors triggering autoimmunity...
