Mucification of the cumulus layer around the oocyte is an obligatory process for female fertility. Tumor necrosis factor-induced protein-6 (TNFIP6 or TSG6) has been shown to be specifically expressed during this process. We have generated TNFIP6-deficient mice and tested the ability of their cumulus cells to undergo mucification. Cumulus cell-oocyte(More)
OBJECTIVE Associations have been found between ankylosing spondylitis (AS) and polymorphisms in the aminopeptidase regulator of TNFR1 shedding (ARTS1) gene. We studied the association of 5 polymorphisms within the ARTS1 gene with AS in Hungarian patients. We also investigated the prevalence of HLA-B27 subtypes in the Hungarian population. METHODS A(More)
In this study, we have documented an essential role for ADP-ribosylation factor 6 (ARF6) in cell surface remodeling in response to physiological stimulus and in the down regulation of stress fiber formation. We demonstrate that the G-protein-coupled receptor agonist bombesin triggers the redistribution of ARF6- and Rac1-containing endosomal vesicles to the(More)
OBJECTIVE Studies indicate that ankylosing spondylitis (AS), as well as rheumatoid arthritis, may be associated with accelerated atherosclerosis and vascular disease. We assessed endothelial dysfunction, carotid atherosclerosis, and aortic stiffness in AS in context with clinical and laboratory measurements. METHODS Forty-three patients with AS and 40(More)
OBJECTIVE To determine the genetic, clinical and serological characteristics of systemic sclerosis (SSc)-rheumatoid arthritis (RA) overlap syndrome. METHODS Clinical manifestations and immunolaboratory features of 22 SSc-RA patients were assessed. The HLA-DR genotype of the 22 SSc-RA patients determined by SSP-PCR was compared with that of 38 SSc(More)
OBJECTIVE Assess ustekinumab efficacy (week 24/week 52) and safety (week 16/week 24/week 60) in patients with active psoriatic arthritis (PsA) despite treatment with conventional and/or biological anti-tumour necrosis factor (TNF) agents. METHODS In this phase 3, multicentre, placebo-controlled trial, 312 adults with active PsA were randomised (stratified(More)
Chemotactic cytokines, termed chemokines, mediate the ingress of leukocytes into the inflamed synovium. In this review, authors discuss the role of the most relevant chemokines and chemokine receptors involved in chronic inflammatory rheumatic diseases. Rheumatoid arthritis was chosen as a prototype to discuss these issues, as the majority of studies on the(More)
Numerous autoimmune-inflammatory rheumatic diseases have been associated with accelerated atherosclerosis or other types of vasculopathy leading to increased cardio- and cerebrovascular disease risk. Traditional risk factors, as well as the role of systemic inflammation including cytokines, chemokines, proteases, autoantibodies, adhesion receptors and(More)
OBJECTIVE To gain insight into the mechanisms of the antiinflammatory effect of tumor necrosis factor alpha (TNFalpha)-induced protein 6 (Tnfip6) in arthritis, using Tnfip6-deficient animals. METHODS TNFalpha-stimulated gene 6 (TSG-6) coding for Tnfip6 was disrupted. Tnfip6-deficient mice were backcrossed into proteoglycan-induced arthritis(More)
