INTRODUCTION Rheumatoid arthritis synovial fibroblasts (RASF) are key players in synovial pathophysiology and are therefore examined extensively in various experimental approaches. We evaluated, whether passaging during culture and freezing has effects on gene expression and cell proliferation. METHODS RASF were passaged for up to 8 passages. RNA was(More)
Synovial pathophysiology is a complex and synergistic interplay of different cell populations with tissue components, mediated by a variety of signaling mechanisms. All of these mechanisms drive the affected joint into inflammation and drive the subsequent destruction of cartilage and bone. Each cell type contributes significantly to the initiation and(More)
BACKGROUND In scrapie and prion diseases, the knowledge concerning genes involved in host response during the early infection period in the lymphoid tissues, still remains limited. In the present study, we have examined differential gene expression in ileal Peyer's patches and in laser microdissected follicles of sheep infected with scrapie. METHODS Ileal(More)
BACKGROUND MicroRNAs (miRNAs) are involved in the neuroplastic changes which induce and maintain neuropathic pain. However, it is unknown whether nerve injury leads to altered miRNA expression and modulation of pain relevant target gene expression within peripheral nerves. In the present study, expression profiles of miR-1 and the pain-relevant targets,(More)
Total knee replacement (TKR) is a common therapeutic option to restore joint functionality in chronic inflammatory joint diseases. Subsequent arthrofibrotic remodeling occurs in 10%, but the underlying pathomechanisms remain unclear. We evaluated the association of xylosyltransferases (XT), fibrotic mediators catalyzing glycosaminoglycan biosynthesis,(More)
Inflammation has been recognized as a common trait in the pathogenesis of multifactorial diseases including obesity, where a low-grade inflammation has been established and may be responsible for the cardiovascular risk related to the disease. Obesity has also been associated with the increased incidence and a worse outcome of rheumatoid arthritis (RA) and(More)
BACKGROUND We investigated two distinct synovial fibroblast populations that were located preferentially in the lining or sub-lining layers and defined by their expression of either podoplanin (PDPN) or CD248, and explored their ability to undergo self-assembly and transmigration in vivo. METHODS Synovial fibroblasts (SF) were cultured in vitro and(More)
The 'How to cite this article' section quoted an incorrect abbreviation for Dina N. Abd-Elshafy. In addition, there were errors in the Author Contributions Statement, " A.D. wrote the initial draft of the manuscript and modified by P.B. Experiments were planned and performed by A.D. and P.B. Initial figure drafts were created mainly by BM (Figures 1–4) and(More)
BACKGROUND MicroRNAs (miRNAs) regulate gene expression in physiological as well as in pathological processes, including chronic pain. Whether deletion of a gene can affect expression of the miRNAs that associate with the deleted gene mRNA remains elusive. We investigated the effects of brain-derived neurotrophic factor (Bdnf) gene deletion on the expression(More)
Glycinergic inhibitory neurotransmission plays a pivotal role in the development of neuropathic pain. The glycine concentration in the synaptic cleft is controlled by the glycine transporters GlyT1 and GlyT2. GlyT1 is expressed throughout the central nervous system, while GlyT2 is exclusively located in glycinergic neurons. Aim of the present study was to(More)
