Cyclic thrombocytopenia complicated with Sjögren syndrome and the mechanism of periodic platelet count fluctuation

Rinsho Ketsueki. 2008 Aug;49(8):658-63 Authors: Yamauchi N, Muramatsu H, Inomata H, Numata T, Nozawa E, Nishino M, Koyama R, Ihara K, Nishisato T, Hirayama M, Katsuki S, Matsunaga T, Niitsu Y Cyclic thrombocytopenia is a rare disorder with periodic changes of the platelet count. We experienced a patient with cyclic thrombocytopenia and Sjögren syndrome (SS),…

Stimulatory role of lysophosphatidic acid in cyclooxygenase-2 induction by synovial fluid of patients with rheumatoid arthritis in fibroblast-like synovial cells.

J Immunol. 2008 Oct 1;181(7):5111-9 Authors: Nochi H, Tomura H, Tobo M, Tanaka N, Sato K, Shinozaki T, Kobayashi T, Takagishi K, Ohta H, Okajima F, Tamoto K While inflammatory cytokines are well-recognized critical factors for the induction of cyclooxygenase-2 (COX-2) in activated fibroblast-like synovial cells, the roles of biologically active components other than inflammatory…

Tumor necrosis factor alpha drives cadherin 11 expression in rheumatoid inflammation.

Arthritis Rheum. 2008 Oct;58(10):3051-62 Authors: Vandooren B, Cantaert T, ter Borg M, Noordenbos T, Kuhlman R, Gerlag D, Bongartz T, Reedquist K, Tak PP, Baeten D OBJECTIVE: Cadherin 11 expressed on fibroblast-like synoviocytes (FLS) plays a key role in normal synovial architecture. The purpose of this study was to examine the expression of cadherin 11…

Scand J Rheumatol. 2008 Nov-Dec;37(6):401-9 Authors: Bramlage CP, Kaps C, Ungethüm U, Bramlage P, Koziolek M, Wessels J, Krenn V, Pruss A, Müller GA, Strutz F, Burmester GR, Häupl T OBJECTIVE: Growth differentiation factor-5 (GDF-5), a member of the transforming growth factor (TGF)-beta family, is involved in joint development during embryogenesis and has the potential…

Mesenchymal stem cells and immunomodulation: toward new immunosuppressive strategies for the treatment of autoimmune diseases?

Rev Med Interne. 2009 Mar;30(3):287-99 Authors: Larghero J, Vija L, Lecourt S, Michel L, Verrecchia F, Farge D Mesenchymal stem cells (MSC) represent a population of the bone marrow microenvironment, which participates in the regulation of haematopoietic stem cells (HSC) self-renewal and differentiation. MSC are multipotent non-haematopoietic progenitors, which have been explored as a promising…

Mesenchymal stem cells in arthritic diseases.

Arthritis Res Ther. 2008;10(5):223 Authors: Chen FH, Tuan RS Mesenchymal stem cells (MSCs), the nonhematopoietic progenitor cells found in various adult tissues, are characterized by their ease of isolation and their rapid growth in vitro while maintaining their differentiation potential, allowing for extensive culture expansion to obtain large quantities suitable for therapeutic use. These properties…

Stem cell transplantation in rheumatoid arthritis.

Autoimmunity. 2008 Dec;41(8):625-31 Authors: Snowden JA, Kapoor S, Wilson AG The therapeutic potential of high dose cytotoxic therapy and stem cell transplantation (SCT) in severe rheumatoid arthritis (RA) was originally supported by animal studies and serendipitous clinical cases where allogeneic and autologous procedures were shown to ameliorate and potentially cure the disease. Phase I and…

Z Rheumatol. 2008 Dec;67(8):684-8 Authors: Albrecht I, Niesner U, Janke M, Radbruch A, Chang H State-of-the-art immunosuppressive therapies, though efficient in the treatment of rheumatic inflammatory disorders, in most cases do not provide a cure. Complete immunablation and the associated deletion of the reactive immunological memory followed by reconstitution of the “healthy” immune system from…
