Biochem Pharmacol. 2010 Jun 1;79(11):1648-57 Authors: Tang CH, Hsu CJ, Yang WH, Fong YC Patients with rheumatoid arthritis (RA) are at increased risk of developing infections and appear to be particularly susceptible to septic arthritis. Lipoteichoic acid (LTA), a cell wall component of Gram-positive bacteria is an amphiphilic, negatively charged glycolipid. However, the effects of…

Arthritis Rheum. 2010 Mar;62(3):683-93 Authors: Sacre S, Medghalchi M, Gregory B, Brennan F, Williams R OBJECTIVE: Selective serotonin reuptake inhibitors (SSRIs), in addition to their antidepressant effects, have been reported to have antiinflammatory effects. The aim of this study was to assess the antiarthritic potential of 2 SSRIs, fluoxetine and citalopram, in murine collagen-induced arthritis…

Scand J Rheumatol. 2010;39(1):1-11 Authors: Szodoray P, Varoczy L, Szegedi G, Zeher M Autoimmune diseases have a multifactorial origin. Because of disturbances of the immune system, autoreactive T and B cells target self-antigens, leading to permanent organ damage. Despite novel therapeutic protocols, the disease course is chronic and in many instances the outcome is lethal.…

Immunol Rev. 2010 Jan;233(1):233-55 Authors: Bartok B, Firestein GS Rheumatoid arthritis (RA) remains a significant unmet medical need despite significant therapeutic advances. The pathogenesis of RA is complex and includes many cell types, including T cells, B cells, and macrophages. Fibroblast-like synoviocytes (FLS) in the synovial intimal lining also play a key role by producing…

Arthritis Res Ther. 2010;12(2):R49 Authors: Page CE, Smale S, Carty SM, Amos N, Lauder SN, Goodfellow RM, Richards PJ, Jones SA, Topley N, Williams AS INTRODUCTION: The first few months after symptom onset represents a pathologically distinct phase in rheumatoid arthritis (RA). We used relevant experimental models to define the pathological role of interferon-gamma (IFN-gamma)…

Cytokine. 2010 Jul;51(1):35-41 Authors: Bader RA, Wagoner KL Although physical therapy has been shown to be an effective method for treatment of rheumatoid arthritis, a thorough investigation on the impact of mechanical signals upon the complex cytokine network associated with pathogenesis has not yet been conducted. In the current study, our research group investigated the…

Curr Opin Investig Drugs. 2010 May;11(5):515-26 Authors: Bourgoin SG, Zhao C Autotaxin (ATX) is an autocrine motility-stimulating factor and an extracellular enzyme that catalyzes the hydrolysis of lysophosphatidylcholine (LPC) to lysophosphatidic acid (LPA). Although ATX can also hydrolyze sphingosylphosphorylcholine (SPC) to sphingosine-1-phosphate (S1P), the major source of extracellular S1P originates from the intracellular phosphorylation of…

HNO. 2010 Jun;58(6):556-63 Authors: Rotter N, Schwarz S, Jakob M, Brandau S, Wollenberg B, Lang S Adult stem cells are actively investigated in the fields of regenerative medicine and tissue engineering, as they exhibit specific characteristics that make them promising candidates for cellular therapies. Depending on their tissue of origin these characteristics include long-term proliferation…

J Cell Biochem. 2010 Oct 1;111(2):249-57 Authors: Chanda D, Kumar S, Ponnazhagan S Mesenchymal stem cells (MSCs) are the most popular among the adult stem cells in tissue engineering and regenerative medicine. Since their discovery and functional characterization in the late 1960s and early 1970s, MSCs or MSC-like cells have been obtained from various mesodermal…

Cell Immunol. 2010;264(1):7-17 Authors: Ichim TE, Harman RJ, Min WP, Minev B, Solano F, Rodriguez JP, Alexandrescu DT, De Necochea-Campion R, Hu X, Marleau AM, Riordan NH Since the days of Medawar, the goal of therapeutic tolerogenesis has been a “Holy Grail” for immunologists. While knowledge of cellular and molecular mechanisms of this process has…
