Conserved TCR β chain usage in reactive arthritis; evidence for selection by a putative HLA-B27-associated autoantigen

2002

Previous work suggested that expanded CD8+ T-cell clones in the synovial fluid (SF) of HLA-B27+ patients with reactive arthritis (ReA) preferentially use the T-cell receptor variable region (TCRBV) 1, similar CDR3 sequences, and joining region (BJ) 2S3. To determine the range of conservation and disease-specificity of CDR3-sequences, we analyzed the TCRBV1-J2S3 repertoire from 33 healthy HLA-B27+ individuals, patients with various types of spondyloarthropathies (SpA), and with rheumatoid arthritis (RA) by CDR3-spectratyping. After collection and database submission of all available TCRB-CDR3 from HLA-B27-restricted or SpA-derived T cells, we systematically screened the entire human sequence…

Targeting of the transcription factor STAT4 by antisense phosphorothioate oligonucleotides suppresses collagen-induced arthritis

2007

Abstract The transcription factor STAT4 mediates signals of various proinflammatory cytokines, such as IL-12, IL-15, and IL-23, that initiate and stabilize Th1 cytokine production. Although Th1 cytokine production has been suggested to play a major pathogenic role in rheumatoid arthritis, the role of STAT4 in this disease is poorly understood. In this study, we demonstrate a key functional role of STAT4 in murine collagen-induced arthritis (CIA). In initial studies we found that STAT4 expression is strongly induced in CD4+ T cells and to a lesser extent in CD11b+ APCs during CIA. To analyze the role of STAT4 for arthritis manifestation, we next investigated the outcome of interfering with S…

The Pro-Inflammatory IL23/IL23R/IL17 Axis Is Active in IL23R-Expressing Circulating CLL Cells in Patients with Poor Prognosis

2012

Abstract Abstract 3889 Inflammatory cytokines play a biological role in the pathogenesis of Chronic lymphocytic leukemia (CLL). IL23 is a pro-inflammatory cytokine involved in T-cell responses and in tissue remodeling. It has been shown that the IL23 receptor (IL23R) is up-regulated in primary acute lymphoblastic leukemia (ALL) cells, and that IL23 inhibits ALL cell growth. Nevertheless, the anti-tumor function of IL23 still remains controversial. The role of the IL23R/IL23 axis in CLL has not been investigated so far. Herein we evaluated the expression pattern of IL23R/IL23 axis and its correlation with progression free survival (PFS) in CLL patients. A total of 233 newly diagnosed Binet s…

Non-conventional forms of HLA-B27 are expressed in spondyloarthritis joints and gut tissue

2016

Objectives Human leukocyte antigen (HLA)-B27 (B27) is the strongest genetic factor associated with development of Ankylosing Spondylitis and other spondyloarthropathies (SpA), yet the role it plays in disease pathogenesis remains unclear. We investigated the expression of potentially pathogenic non-conventional heavy chain forms (NC) of B27 in synovial and intestinal tissues obtained from SpA patients. We also determined the presence of NC-B27 in joints, lymphoid and gastrointestinal tissue from B27 transgenic (TG1) rats with M.tuberculosis-induced SpA. Methods Expression of NC-B27 in human SpA joints and gut and in (21-3 × 283-2)F1 HLA-B27/Huβ2m rat tissue was determined by immunohistochem…

Zīdaiņu barošanas veids, pēcdzemdību saikne ar bērnu un pēcdzemdību depresija

2015

Pētījuma mērķis bija izpētīt vai un kādas ir pēcdzemdību depresijas un kādas ir pēcdzemdību saiknes atšķirības mātēm, kas bērnu baro ar krūti, un mātēm, kas bērnu ar krūti nebaro, un kādas ir pēcdzemdību saiknes ar bērnu atšķirības mātēm, kas bērnu baro ar krūti, un mātēm, kas bērnu ar krūti nebaro. Pētījumā piedalījās bērnu mātes, kurām bērni bija vecumā līdz 6 mēnešiem (n=60). Pētījumā tika izmantotas metodes: Pēcdzemdību saiknes aptauja (The Postpartum Bonding Questionnaire (PBQ) un Edinburgas pēcdzemdību depresijas skala (Edinburg Postnatal Depression Scale (EPDS) kā arī respondentu grupēšana ar papildus jautājumu, lai noskaidrotu zīdaiņa barošanas veidu (barošana ar krūti vai mātes pie…

Microwave-assisted synthesis of semiconductor nanoparticles in water/oil microemulsion

2005

Stable CdS and ZnS nanoparticles with exalted luminescence properties have been obtained in water/sodium bis (2-ethylhexyl) sulfosuccinate (AOT)/n-heptane microemulsion using microwave in order to take away selectively water molecules from microemulsion system. The nanoparticles synthesis was performed using a microwave exposure set-up opportunely assembled that allows irradiating the reactor with microwave of 2.45 GHz maintaining constant the temperature. The nanoparticles growth kinetics, as a function of irradiation time, was performed by means of UV-Vis spectroscopy. Information about the structural changes that microemulsion undergoes when irradiated with microwave was obtained by mean…

The Impact of Single-Level ACDF on Neural Foramen and Disc Height of Surgical and Adjacent Cervical Segments: A Case-Series Radiological Analysis

2023

Background: ACDF has become one of the established procedures for the surgical treatment of symptomatic cervical spondylosis, showing excellent clinical results and effective improvements in neural functions and neck pain relief. The main purpose of ACDF is neural decompression, and it is considered by some authors as an indirect result of the intervertebral distraction and cage insertion and the consequent restoration of the disc space and foramen height. Methods: Radiological data from 28 patients who underwent single-level ACDF were retrospectively collected and evaluated. For neural foramen evaluation, antero-posterior (A-P) and cranio-caudal (C-C) diameters were manually calculated; fo…
