The Differences Between Childhood and Adult Onset Antiphospholipid Syndrome.

Front Pediatr 2018 27;6:362. Epub 2018 Nov 27.

Department of Rheumatology, University College London, London, United Kingdom.

Antiphospholipid syndrome (APS) is a rare autoimmune disease of unknown etiology that represents a leading cause of acquired thromboembolism and recurrent miscarriage. It is characterized by the persistent elevated presence of pathogenic antiphospholipid auto-antibodies directed against cardiolipin, ß2-glycoprotein-I, and/or a positive lupus anticoagulant test. As with many autoimmune disorders, the pathogenesis of APS is believed to be the result of a complex interaction between environmental triggers and genetic predisposition. Read More

Inhibition of Membrane-Bound BAFF by the Anti-BAFF Antibody Belimumab.

Front Immunol 2018 20;9:2698. Epub 2018 Nov 20.

Department of Biochemistry, University of Lausanne, Lausanne, Switzerland.

B cell activating factor of the TNF family (BAFF, also known as BLyS), a cytokine that regulates homeostasis of peripheral B cells, is elevated in the circulation of patients with autoimmune diseases such as systemic lupus erythematosus (SLE). BAFF is synthetized as a membrane-bound protein that can be processed to a soluble form after cleavage at a furin consensus sequence, a site that in principle can be recognized by any of the several proteases of the pro-protein convertase family. Belimumab is a human antibody approved for the treatment of SLE, often cited as specific for the soluble form of BAFF. Read More

Neutrophils in lupus nephritis.

Curr Opin Rheumatol 2018 Dec 11. Epub 2018 Dec 11.

Center for Excellence in Vascular Biology, Department of Pathology, Brigham and Women's Hospital & Harvard Medical School, Boston, USA.

Purpose Of Review: Systemic lupus erythematosus (SLE) is a multiorgan autoimmune disease characterized by IgG-autoantibodies to nuclear antigens that can deposit in the kidney and trigger lupus nephritis. Neutrophils accumulate in the kidneys of patients with proliferative LUPUS NEPHRITIS and neutrophil products and a subset of granulocytes, called low-density granulocytes (LDG) may contribute to lupus nephritis pathogenesis. Here, we will discuss recent studies implicating neutrophils in the pathogenesis of human SLE nephritis and then examine studies that provide mechanistic insights into how these cells are recruited to the glomerulus following immune complex deposition and how their products may promote lupus nephritis.

Detection of Autoantibodies to Complement Components by Surface Plasmon Resonance-Based Technology.

Methods Mol Biol 2019 ;1901:271-280

INSERM, UMR_S 1138, Centre de Recherche des Cordeliers, Paris, France.

The innate immune complement system is a powerful defense cascade against pathogens, but can induce host tissue damage when overactivated. In pathological conditions, mainly but not restricted to renal diseases, such as lupus nephritis, atypical hemolytic uremic syndrome, and C3 glomerulopathies, complement is overactivated or dysregulated by autoantibodies directed against its components and regulators. Among the key autoantibody targets are the initiator of the classical complement pathway C1q, the alternative pathway regulator Factor H, the components of the alternative pathway C3 convertase complex C3 and Factor B and the convertase complex itself.

Analysis of Anti-C1q Autoantibodies by Western Blot.

Methods Mol Biol 2019 ;1901:183-189

Clinical Immunology and Transfusion Medicine, Region Skåne, Sweden.

Anti-C1q autoantibodies may be found in many conditions, most commonly in systemic lupus erythematosus (SLE) and hypocomplementemic urticarial vasculitis syndrome (HUVS), and are diagnostic markers as well as disease activity markers in lupus nephritis. Sera from patients with SLE and HUVS show partly distinct autoantibody reactivities to separated protein chains B and C of the first component of complement, C1q. These different binding specificities can be detected by Western blot analysis of the autoantibodies under reducing conditions. Read More

Detection of DNA Autoantibodies by Electrophoretic Mobility Shift Assay.

Methods Mol Biol 2019 ;1901:133-152

Laboratory for Life Sciences, Tehran, Iran.

Although the presence of antibodies against double-stranded (ds) DNA is considered the serological hallmark of systemic lupus erythematosus (SLE), it is not detected in all SLE patients by routine laboratory tests. Looking at DNA-anti(ds)DNA interaction as one kind of DNA-protein interaction gave us the grounds for a novel type of assay, easy to perform, and providing a direct insight on DNA-anti(ds)DNA IgG interaction. The assay is an application of the electrophoretic mobility shift assay (EMSA) and is based on the observation that the electrophoretic mobility of a DNA-protein complex is typically less than that of free DNA.

An Efficient Method to Generate Monoclonal Antibodies from Human B Cells.

Methods Mol Biol 2019 ;1904:109-145

Department of Medicine, Section of Rheumatology, The Knapp Center for Lupus and Immunology, University of Chicago, Chicago, IL, USA.

In the age of personalized medicine, an efficient method to generate monoclonal antibodies (mAbs) is essential for biomedical and immunotherapeutic research. Numerous aspects of basic B-cell biology can be studied at the monoclonal level, including B-cell development, antibody responses to infection or vaccination, and autoimmune responses. Single-cell B-cell receptor cloning allows for the rapid generation of antigen-specific mAbs in a matter of several weeks. Read More

Habitat use of sympatric prey suggests divergent anti-predator responses to recolonizing gray wolves.

Oecologia 2018 Dec 11. Epub 2018 Dec 11.

School of Environmental and Forest Sciences, University of Washington, Seattle, WA, USA.

The non-consumptive effects of predators on prey are now widely recognized, but the need remains for studies identifying the factors that determine how particular prey species respond behaviorally when threatened with predation. We took advantage of ongoing gray wolf (Canis lupus) recolonization in eastern Washington, USA, to contrast habitat use of two sympatric prey species-mule (Odocoileus hemionus) and white-tailed (O. virginianus) deer-at sites with and without established wolf packs.

An Unusual Presentation of Lupus Vulgaris and the Practical Usefulness of Dermatoscopy.

Case Rep Dermatol Med 2018 14;2018:1036162. Epub 2018 Nov 14.

Specialist in Dermatology-Venereology, Chief of State Clinic of Dermatology, Hospital for Skin and Venereal Diseases, Delfon 124, 54643 Thessaloniki, Greece.

We report a case report of lupus vulgaris (LV) presented on the extremities of an 80-year-old man. He was misdiagnosed as having psoriasis and referred to our department for a second-opinion evaluation. The discrepancy between the clinical manifestation which was misleading and the dermatoscopic findings raised the suspicion of an underlying granulomatous disease and we proceeded to skin biopsy.
