    Compact Bone-Derived Multipotent Mesenchymal Stromal Cells (MSCs) for the Treatment of Sjogren's-like Disease in NOD Mice.
    Methods Mol Biol 2017 ;1553:25-39
    Craniofacial Tissue Engineering and Stem Cells Laboratory, Faculty of Dentistry, McGill University, 3640 University Street, M43, Montreal, QC, Canada.
    Compact bone (cortical or dense bone) is among the organs that contain multipotent mesenchymal stromal cells (MSCs). Unlike bone marrow plugs where MSCs were initially isolated, compact bone has minimal (amount of) hematopoietic cells and thus facilitates the MSCs isolation process. In vitro, MSCs from compact bone show multipotency and differentiation into mesenchymal tissues such as bone, adipose, and cartilage, under certain conditions. Read More

    La deletion from mouse brain alters pre-tRNA metabolism and accumulation of pre-5.8S rRNA, with neuron death and reactive astrocytosis.
    Mol Cell Biol 2017 Feb 21. Epub 2017 Feb 21.
    Commisioned Corps, U.S. Public Health Service, Rockville, Maryland
    Human La antigen (Sjögren's syndrome antigen B, SSB) is an abundant multifunctional RNA-binding protein. In the nucleoplasm, La binds to and protects from 3' exonucleases, the ends of precursor-tRNAs and other transcripts synthesized by RNA polymerase III, and facilitates their maturation, while a nucleolar isoform has been implicated in rRNA biogenesis by multiple independent lines of evidence. We showed earlier that conditional La knockout (La cKO) from mouse cortex neurons results in defective tRNA processing although pathway(s) involved in neuronal loss thereafter was unknown. Read More

    Targeting BAFF and APRIL in systemic lupus erythematosus and other antibody-associated diseases.
    Int Rev Immunol 2017 Jan;36(1):3-19
    d Department of Biochemistry , University of Lausanne , Lausanne , Switzerland.
    The B cell-stimulating molecules, BAFF (B cell activating factor) and APRIL (a proliferation-inducing ligand), are critical factors in the maintenance of the B cell pool and humoral immunity. In addition, BAFF and APRIL are involved in the pathogenesis of a number of human autoimmune diseases, with elevated levels of these cytokines detected in the sera of patients with systemic lupus erythematosus (SLE), IgA nephropathy, Sjögren's syndrome, and rheumatoid arthritis. As such, both molecules are rational targets for new therapies in B cell-driven autoimmune diseases, and several inhibitors of BAFF or BAFF and APRIL together have been investigated in clinical trials.

    Interleukin-33 produced by M2 macrophages and other immune cells contributes to Th2 immune reaction of IgG4-related disease.
    Sci Rep 2017 Feb 13;7:42413. Epub 2017 Feb 13.
    Section of Oral and Maxillofacial Oncology, Division of Maxillofacial Diagnostic and Surgical Sciences, Faculty of Dental Science, Kyushu University, Fukuoka, Japan.
    IgG4-related disease (IgG4-RD) is characterized by elevated serum IgG4 and marked infiltration of IgG4-positive cells in multiple organs. Interleukin-33 (IL-33) is a recently described cytokine that is secreted by damaged epithelial cells, macrophages, and dendritic cells, and potently activates helper T type 2 (Th2) immune responses, which have been suggested to play a major role in IgG4 production of IgG4-RD. Here, we assessed the expression of IL-33 and related molecules in the salivary glands (SGs) of patients with IgG4-RD versus that in patients with Sjögren's syndrome (SS) and controls. Read More

    Ectopic lymphoid neogenesis in rheumatic autoimmune diseases.
    Nat Rev Rheumatol 2017 Mar 9;13(3):141-154. Epub 2017 Feb 9.
    Centre for Experimental Medicine and Rheumatology, John Vane Science Centre, William Harvey Research Institute, Barts and the London School of Medicine and Dentistry, Queen Mary University of London, Charterhouse Square, London EC1M 6BQ, UK.
    Ectopic lymphoid neogenesis often occurs in the target tissues of patients with chronic rheumatic autoimmune diseases such as rheumatoid arthritis, Sjögren syndrome and other connective tissue disorders, including systemic lupus erythematosus and myositis. However, the mechanisms of ectopic lymphoid-like structure (ELS) formation and function are not entirely understood. For example, it is unclear whether ELSs indicate distinct disease phenotypes or whether they are evolutionary manifestations of chronic inflammation. Read More

    Anti-Ro/SS-A is one specific type of antinuclear antibodies. They are in the majority of cases associated with primary Sjögren syndrome (SS) but also in Systemic Lupus Erythematosus (SLE), rheumatoid arthritis (RA), and in healthy people. During pregnancy, they are mainly associated to congenital heart block (CHB) and neonatal lupus (NL). Read More

    Experiments with B cell-deficient (B-/-) mice indicate that a number of autoimmune diseases require B cells in addition to T cells for their development. Using B-/- Non-obese diabetic (NOD) and NOD.H-2h4 mice, we demonstrated that development of spontaneous autoimmune thyroiditis (SAT), Sjogren's syndrome and diabetes do not develop in B-/- mice, whereas all three diseases develop in B cell-positive wild-type (WT) mice.

    POEMS syndrome (polyneuropathy, organomegaly, endocrinopathy, monoclonal gammopathy, and skin changes) is a paraneoplastic syndrome driven by plasma cell dyscrasias. We report a patient with novel initial manifestation of polyneuropathy, which was considered due to Sjögren's syndrome but with poor response to methylprednisolone (120 mg/d) and intravenous immunoglobulin (IVIg). Further investigation by imaging tests and following biopsy eventually confirmed the diagnosis of POEMS syndrome secondary to solitary plasmocytoma. Read More

    A 33 year-old woman presented with intentional incontinence, motor aphasia, supranuclear gaze palsy, and spasticity after parotitis. Brain magnetic resonance images (MRI) showed abnormal signaling in long corticospinal tract involving internal capsules and cerebral peduncles, middle cerebellar peduncle, and frontal subcortical white matter lesions. She had a long history of dry eye and mouth. Read More
