Objective- The purpose of present study was to investigate the viability of equine fibroblast-like synoviocytes (FLSs) treated with doxycycline. Design- Experimental study. Sample population- FLSs from metacarpophalangeal joints of six skeletally mature horses. Methods- FLSs were established from synovial fluids of healthy joints. The cells were treated with different concentr...
Recent advances in post-genomic technology enable us to analyze gene expression and protein modification comprehensively in tissues and cells, resulting in new developments in the analysis of molecular events of diseases. We have been studying the pathogenic and progressive mechanisms of diseases from the aspect of signalling pathways of cells. Inflammatory cytokines such as TNF-alpha and IL-1 ...
The activation of a vanilloid type 4 transient receptor potential channel (TRPV4) has an obligatory role in regulation of intracellular Ca(2+) (Ca(2+)(i)) in several types of cells including vascular and sensory organs. In this study, we provide evidence that TRPV4 is a functional regulator of Ca(2+)(i) in human synoviocytes. Although significant expression of TRPV4 in synoviocytes from patient...
INTRODUCTION Interleukin (IL)-6-type cytokines exert their effects through activation of the Janus kinase/signal transducers and activators of transcription (JAK/STAT) signaling cascade. The JAK/STAT pathways play an important role in rheumatoid arthritis, since JAK inhibitors have exhibited dramatic effects on rheumatoid arthritis (RA) in clinical trials. In this study, we investigated the mol...
Human tumour necrosis factor (TNF)-like weak inducer of apoptosis (hTWEAK) and two anti-hTWEAK mAbs were tested for their ability to elicit or block inflammatory responses in cultured human dermal fibroblasts and synoviocytes. Incubation with hTWEAK increased the production of prostaglandin E2, matrix metalloproteinase-1 (MMP-1), IL-6, and the chemokines IL-8, RANTES (regulated on activation, n...
An excess of the proinflammatory substance IL-18 is present in joints of patients with rheumatoid arthritis (RA), and expression of IL-18 receptor (IL-18R) regulates IL-18 bioactivity in various cell types. We examined the expression of IL-18R alpha-chain and beta-chain and the biologic effects of IL-18 in fibroblast-like synoviocytes (FLS) after long-term culture. The presence of both IL-18R c...
Calcium crystals are present in the synovial fluid of 65%-100% patients with osteoarthritis (OA) and 20%-39% patients with rheumatoid arthritis (RA). This study sought to investigate the role of fibroblast-like synoviocytes (FLSs) in calcium mineral formation. We found that numerous genes classified in the biomineral formation process, including bone gamma-carboxyglutamate (gla) protein/osteoca...
INTRODUCTION Chemerin is a chemotactic agonist identified as a ligand for ChemR23 that is expressed on macrophages and dendritic cells (DCs). In this study, we analyzed the expression of chemerin and ChemR23 in the synovium of rheumatoid arthritis (RA) patients and the stimulatory effects of chemerin on fibroblast-like synoviocytes (FLSs) from RA patients. METHODS Chemerin and ChemR23 express...
