    B Cells Are Indispensable for a Novel Mouse Model of Primary Sjögren's Syndrome.
    Front Immunol 2017 24;8:1384. Epub 2017 Oct 24.
    Xiamen-Borstel Joint Laboratory of Autoimmunity, Medical College of Xiamen University, Xiamen, China.
    Primary Sjögren's syndrome (pSS) is characterized by a panel of autoantibodies, while it is not clear whether B cells and autoantibodies play an essential role in pathogenesis of the disease. Here, we report a novel mouse model for pSS which is induced by immunization with the Ro60_316-335 peptide containing a predominant T cell epitope. After immunization, mice developed several symptoms mimicking pSS, including a decreased secretion of tears, lymphocytic infiltration into the lacrimal glands, autoantibodies, and increased levels of inflammatory cytokines.

    Sci Rep 2017 Nov 6;7(1):14537. Epub 2017 Nov 6.
    Molecular and Cellular Therapeutics, Royal College of Surgeons in Ireland, 123 St. Stephen's Green, Dublin 2, Ireland.
    La/SS-B (or La) is a 48 kDa RNA-binding protein and an autoantigen in autoimmune disorders such as systemic lupus erythematosus (SLE) and Sjögren's syndrome (SS). La involvement in regulating the type I interferon (IFN) response is controversial - acting through both positive and negative regulatory mechanisms; inhibiting the IFN response and enhancing viral growth, or directly inhibiting viral replication. We therefore sought to clarify how La regulates IFN production in response to viral infection. Read More

    Activation of plasmacytoid dendritic cells by apoptotic particles - mechanism for the loss of immunologic tolerance in Sjögren's syndrome.

    Cytokines as therapeutic targets in primary Sjögren syndrome.
    Pharmacol Ther 2017 Oct 29. Epub 2017 Oct 29.
    Sjögren Syndrome Research Group (AGAUR), Laboratory of Autoimmune Diseases Josep Font, CELLEX-IDIBAPS, Spain; Autoimmune Diseases Unit, Department of Medicine, Hospital CIMA-Sanitas, Barcelona, Spain; Department of Autoimmune Diseases, ICMiD, Hospital Clínic Barcelona, Spain.
    Primary Sjögren syndrome (SjS) is a systemic autoimmune disease that may affect 1 in 1000 people (overwhelmingly women) and that can be a serious disease with excess mortality due to severe organ-specific involvements and the development of B cell lymphoma; systemic involvement clearly marks the disease prognosis, and strongly suggests the need for closer follow-up and more robust therapeutic management. Therapy is established according to the organ involved and severity. As a rule, the management of systemic SjS should be organ-specific, with glucocorticoids and immunosuppressive agents limited to potentially-severe involvements; unfortunately, the limited evidence available for these drugs, together with the potential development of serious adverse events, makes solid therapeutic recommendations difficult.

    Antigen-driven lymphoproliferations in Sjögren's Syndrome patients accumulate in complement receptor 2/CD21(-/low) B cells.
    Arthritis Rheumatol 2017 Oct 26. Epub 2017 Oct 26.
    Department of Immunobiology, Yale University School of Medicine, New Haven, Connecticut, USA.
    Objective: Sjögren's Syndrome (SS) patients are prone to develop malignant lymphomas and a correlation has been established between lymphoproliferations and the presence in patients' blood of an unusual B cell population that downregulated complement receptor 2/CD21. We sought to determine from which B cell compartment lymphoproliferations in SS patients emerge and what are the mechanisms that promote these clonal B cell expansions.

    Methods: Using a PCR-based approach that allows us to clone and express, in vitro, recombinant antibodies produced by single B cells, we tested the reactivity of antibodies expressed by CD19(+) CD10(-) CD27(-) IgM(+) CD21(-/low) cells from SS patients. Read More

    An accurate dissection of peripheral blood enumeration is lacking in primary Sjögren's syndrome. The purpose of this study was to quantify different leukocyte populations in peripheral blood of patients with pSS. Numbers of specific leukocyte subsets were determined in 86 pSS patients and 74 healthy donors quantifying 21 distinct subtypes by flow cytometry. Read More

    Background: Systemic lupus erythematosus (SLE) and primary Sjögren's syndrome (pSS) are autoimmune disorders characterized by autoantibodies, dysregulated B cells, and notably high female-to-male incidence ratios. Genome-wide association studies have identified several susceptibility SNPs for both diseases. Many SNPs in the genome are expression quantitative trait loci (eQTLs), with context-dependent effects.

    Objective To assess the inter- and intraobserver reliability of ultrasound of major salivary glands in patients clinically suspected of having primary Sjögren's syndrome (pSS) as well as to assess sources of variation in outcomes of ultrasonographic evaluation. Methods 80 consecutive outpatients with clinically suspected pSS underwent ultrasound evaluation. The following ultrasound variables of the parotid and submandibular salivary glands were assessed: echogenicity, parenchymal homogeneity, presence of hypoechogenic areas, hyperechogenic reflections and clearness of posterior glandular border, according to the scoring system of Hocevar et al.
