    Agonistic Anti-PDGF Receptor Autoantibodies from Patients with Systemic Sclerosis Impact Human Pulmonary Artery Smooth Muscle Cells Function In Vitro.
    Front Immunol 2017 8;8:75. Epub 2017 Feb 8.
    Clinica Medica, Dipartimento di Scienze Cliniche e Molecolari, Università Politecnica delle Marche , Ancona , Italy.
    One of the earliest events in the pathogenesis of systemic sclerosis (SSc) is microvasculature damage with intimal hyperplasia and accumulation of cells expressing PDGF receptor. Stimulatory autoantibodies targeting PDGF receptor have been detected in SSc patients and demonstrated to induce fibrosis in vivo and convert in vitro normal fibroblasts into SSc-like cells. Since there is no evidence of the role of anti-PDGF receptor autoantibodies in the pathogenesis of SSc vascular lesions, we investigated the biologic effect of agonistic anti-PDGF receptor autoantibodies from SSc patients on human pulmonary artery smooth muscle cells and the signaling pathways involved.

    Morphea "en coup de sabre": An unusual oral presentation.
    J Clin Exp Dent 2017 Feb 1;9(2):e315-e318. Epub 2017 Feb 1.
    DDS, MSc, Department of Oral Medicine and Oral Pathology, Universidad Andres Bello, Viña del Mar, Chile. Avenida Valparaíso 1560, Viña del Mar, Chile.
    Morphea, or localized scleroderma, is an inflammatory disease that leads to sclerosis of the skin and underlying tissues due to excessive collagen deposition. Oral involvement is unusual and it may produce white linear fibrotic areas with a scar-like appearance, atrophy of tongue papillae, gingival recession and alveolar bone resorption. We report a case of a 13-year-old girl who consulted for progressive recession on the attached gingiva of her upper left incisors. Read More

    Isolated Ro52 Antibodies as Immunological Marker of a Mild Phenotype of Undifferentiated Connective Tissue Diseases.
    Int J Rheumatol 2017 22;2017:3076017. Epub 2017 Jan 22.
    Immunology Unit, Central Laboratory, Complejo Hospitalario Universitario de Canarias, Tenerife, Spain.
    The term undifferentiated connective tissue disease (UCTD) is used to describe undiagnosed patients that do not fulfill classification criteria for definite connective tissue disease (Systemic Lupus, Systemic Sclerosis, Sjögren Syndrome, and Dermatomyositis/Polymyositis). It is important to find serological markers as predictors of the evolution or severity of these diseases. The objective of this retrospective study was to investigate if there was a milder subgroup of UCTD with a special clinical profile consisting only in the presence of anti-Ro52 autoantibodies.

There are no disease modifying therapies for this condition and the treatment remains symptomatic, largely owing to the lack of a clear understanding of its pathogenesis.

    Aims: To investigate novel aspects of the pathogenesis of gastrointestinal involvement in SSc. Read More

    Recent advances in managing systemic sclerosis.
    F1000Res 2017 30;6:88. Epub 2017 Jan 30.
    Division of Rheumatology, Medicine III, University Medical Center and Faculty of Medicine Carl Gustav Carus at the TU Dresden, Dresden, Germany.
    How the main components in systemic sclerosis-namely autoimmunity, vasculopathy, and fibrosis-fit together is still not sufficiently clear. However, vascular treatment options are well established, the body of evidence for the efficacy of immunomodulatory approaches is increasing, and now at least one hopeful substance that may directly interfere with fibrosis is being tested. Although we still wait for important breakthroughs, there is grounds for hope that better therapeutic options will be available in the near future. Read More

    Proangiogenic effects of soluble α-Klotho on systemic sclerosis dermal microvascular endothelial cells.

    Oral Multiple Sclerosis Drugs Inhibit the In vitro Growth of Epsilon Toxin Producing Gut Bacterium, Clostridium perfringens.
    Front Cell Infect Microbiol 2017 25;7:11. Epub 2017 Jan 25.
    Laboratory of Bacterial Pathogenesis and Immunology, Rockefeller University New York, NY, USA.
    There are currently three oral medications approved for the treatment of multiple sclerosis (MS). Two of these medications, Fingolimod, and Teriflunomide, are considered to be anti-inflammatory agents, while dimethyl fumarate (DMF) is thought to trigger a robust antioxidant response, protecting vulnerable cells during an MS attack. We previously proposed that epsilon toxin from the gut bacterium, Clostridium perfringens, may initiate newly forming MS lesions due to its tropism for blood-brain barrier (BBB) vasculature and central nervous system myelin.

    Nanobiomaterials' applications in neurodegenerative diseases.
    J Biomater Appl 2017 Feb 11;31(7):953-984. Epub 2016 Nov 11.
    4 Nanotechnology Laboratory, National Institute of Neurology and Neurosurgery, México City, Manuel Velasco Suárez, Mexico.
    The blood-brain barrier is the interface between the blood and brain, impeding the passage of most circulating cells and molecules, protecting the latter from foreign substances, and maintaining central nervous system homeostasis. However, its restrictive nature constitutes an obstacle, preventing therapeutic drugs from entering the brain. Usually, a large systemic dose is required to achieve pharmacological therapeutic levels in the brain, leading to adverse effects in the body. Read More

    Vitamin D in Autoimmunity: Molecular Mechanisms and Therapeutic Potential.
    Front Immunol 2016 20;7:697. Epub 2017 Jan 20.
    Department of Rheumatology, Erasmus MC, University Medical Center, Rotterdam, Netherlands; Department of Immunology, Erasmus MC, University Medical Center, Rotterdam, Netherlands.
    Over the last three decades, it has become clear that the role of vitamin D goes beyond the regulation of calcium homeostasis and bone health. An important extraskeletal effect of vitamin D is the modulation of the immune system. In the context of autoimmune diseases, this is illustrated by correlations of vitamin D status and genetic polymorphisms in the vitamin D receptor with the incidence and severity of the disease.
