spondylarthropathies/tyrosine

Spondylarthritis (SpA) is an inflammatory rheumatic disease associated with increased incidence of major adverse cardiovascular events (MACEs). Recently, Paramarta et al. proposed the use of the tyrosine kinase inhibitor Nilotinib in Spondyloarthritis to target certain inflammatory pathways.

To evaluate the immunomodulating and clinical effects of nilotinib, a tyrosine kinase inhibitor, in a proof-of-concept study in spondyloarthritis (SpA) assessing the mast cell as potential novel therapeutic target in this disease. Twenty eight patients with active peripheral (pSpA) and/or axial SpA

The close association between HLA-B27 and spondyloarthropathies remains unexplained. Twelve HLA-B27 subtypes designated B*2701 to B*2712 have been described in various populations. Variations in the ability of these alleles to carry susceptibility to spondyloarthropathies may exist, and may be

BACKGROUND We previously described the presence of nerve growth factor receptors in the inflamed synovial compartment. Here we investigated the presence of the corresponding nerve growth factors, with special focus on nerve growth factor (NGF). METHODS mRNA expression levels of four ligands (NGF,

Uveitis is a frequently occurring extra-articular manifestation of spondyloarthropathies (SpAs), ankylosing spondylitis (AS), reactive arthritis (ReA), psoriatic arthritis (PsA) and inflammatory bowel disease (IBD), occurring in both adults and children with SpA. Uveitis occurs with varying

HLA-B27-associated spondyloarthritides are associated with an altered intestinal microbiota and bowel inflammation. We undertook this study to identify HLA-B27-dependent changes in both host and microbial metabolites in the HLA-B27/β2 -microglobulin (β2 m)-transgenic rat and to determine whether

B*2704 and B*2706 are two closely related HLA-B27 subtypes, which differ from the common B*2705 by the Asp > Ser77, Val > Glu152, and Ala > Gly211 amino acid changes. In addition, B*2706 differs from B*2704 by the His > Asp114 and Asp > Tyr116 changes. In spite of their similarity B*2704, but not

Alkaptonuria (AKU) is a hereditary disorder that results from altered structure and function of homogentisate 1,2 dioxygenase (HGD). This enzyme, predominantly produced by liver and kidney, is responsible for the breakdown of homogentisic acid (HGA), an intermediate in the tyrosine degradation

Autoimmune diseases have become a major medical problem of recent years. Celiac disease is an autoimmune disease model. The aim of our study was to follow the changes in the clinical autoimmunity picture of the celiac disease from recent years. The study of autoimmunity in celiac disease has focused

Selected HLA-B27 subtypes are associated with spondyloarthropathies, but the underlying mechanism is not understood. To explain this association in molecular terms, a comparison of peptide-dependent dynamic and structural properties of the differentially disease-associated subtypes HLA-B*2705 and

To dissect the mechanisms of anti-TNFα-induced autoimmunity we examined the phenotype and function of B cells from anti-TNFα-treated patients. Levels of Lyn, Syk, SHP-1, tyrosine 348 phospho-Syk (Y348-Syk) and tyrosine phosphorylated (P-Y) proteins were evaluated and B-cell-surface CD20, CD21 and

Ochronosis is a disease of tyrosine metabolism. Although most commonly associated with alcaptonuria and spondyloarthropathy, cardiovascular abnormalities have been associated. We describe a case which exemplifies the cardiovascular findings in this entity.

OBJECTIVE The present study first utilized a standardized shotgun proteomic analysis method to determine differences in protein expression of fibroblasts in the ligament between AS patients and healthy controls. METHODS Proteins extracted from primarily cultured FLLs from 35 AS patients and 10

Ochronosis is a rare disorder of tyrosine metabolism due to a deficiency of the enzyme homogentisic acid oxidase. The most common clinical manifestations include alkaptonuria, spondyloarthropathy, large joint arthritides and pigmentation of cartilage. Cardiac involvement may occur due to the
