Membrane peptidases play important roles in cell activation, proliferation and communication. Human fibroblast-like synoviocytes express considerable amounts of aminopeptidase N/CD13, dipeptidyl peptidase IV/CD26, and neprilysin/CD10, transmembrane proteins previously proposed to be involved in the regulation of intra-articular levels of neuropeptides and chemotactic mediators as well as in adh...

Human activated T cells adhere to synovial fibroblast-like cells in vitro. The present study was conducted to investigate the consequences of T cell-synovial fibroblast interactions with regard to induction of adhesion molecules and proinflammatory cytokines. A sensitive Western blot technique, polymerase chain reaction (PCR) amplification, and fluorescence-activated cell sorter (FACS) analysis...

Background Rheumatoid Arthritis (RA) is a chronic inflammatory disease, which characterized by synovial inflammation resulting in bone and cartilage destruction. Crosstalk between activated fibroblast-like synoviocytes (FLS) immune cells, such as CD4 + T within the synovium might amplify joint Objectives To define interaction profile of FLS cells an setting to elucidate its consequence on infla...

Casticin, as a major effective component in Chinese herbal medicine Vitex agnus-castus exhibits an antiinflammatory property to rheumatoid arthritis (RA), while the potential mechanism is unclear. We aim at investigating the mechanism of Casticin on lipopolysaccharides (LPS)-induced fibroblast-like synoviocytes (LiFLSs) inflammation model. Fibroblast-like synoviocytes (FLSs) were treated with 2...

INTRODUCTION In the present study, we investigated the ability of microparticles isolated from synovial fluids from patients with rheumatoid arthritis or osteoarthritis to induce the synthesis and release of key cytokines of B-lymphocyte modulation such as B cell-activating factor, thymic stroma lymphopoietin, and secretory leukocyte protease inhibitor by rheumatoid fibroblast-like synoviocytes...
