Influence of HLA-B27 on the Ankylosing Spondylitis phenotype: results from the REGISPONSER database

Arthritis Research & Therapy, 2018
Objective To assess HLA-B27 influence on the clinical phenotype of Ankylosing Spondylitis (AS) patients. Method An observational, cross-sectional and descriptive study of AS patients from the Spanish REGISPONSER database was performed.

Measuring the Impact: Magnetic Resonance Imaging Response of Sacroiliac Joints to Tumor Necrosis Factor Inhibitors in Youth With Axial Disease

Arthritis &Rheumatology, EarlyView.
Objective To evaluate the timeline for resolution of sacroiliac joint (SIJ) inflammation, changes in structural lesions, and their correlation with patient‐reported outcomes (PROs) in youth with axial juvenile spondyloarthritis (axJSpA) initiating tumor necrosis factor inhibitor (TNFi).

Phosphorylation of STAT-1 serine 727 is prolonged in HLA-B27-expressing human monocytic cells. [PDF]

PLoS ONE, 2013
A tissue antigen, HLA-B27, is strongly associated with a group of rheumatic diseases called spondyloarthritides. Despite the intensive research, the exact role of HLA-B27 in the pathogenesis of these diseases is still unclear. Here we studied whether HLA-

Putative Pathobionts in HLA-B27-Associated Spondyloarthropathy

Frontiers in Immunology, 2021
Spondyloarthritis (SpA) is a group of immune mediated inflammatory diseases with a strong association to the major histocompatibility (MHC) class I molecule, HLA-B27. Although the association between HLA-B27 and AS has been known for almost 50 years, the

Monocytes with trained immunity–like signatures are associated with acute anterior uveitis in ankylosing spondylitis

Interdisciplinary Medicine, EarlyView.
In ankylosing spondylitis‐acute anterior uveitis (AS‐AAU), trained immunity monocytes (Mono‐TI) differentiate into macrophages in the eye, retaining trained immunity features. Mono‐TI cells secrete pro‐inflammatory cytokines and chemokines, including IL‐1β, TNF‐α, and CCL3.

HLA-B27 frequency in a group of patients with psoriatic arthritis Freqüência de HLA-B27 em uma amostra de pacientes com artrite psoriática

Anais Brasileiros de Dermatologia, 2012
BACKGROUND: HLA-B27 is associated with spondyloarthritis, a group of diseases that includes psoriatic arthritis. OBJECTIVES: To describe the HLA-B27 frequency in a group of Brazilian patients with psoriatic arthritis and correlate its presence or absence

Mydriasis as a Secondary Effect in Patients With HLA‐B27–Associated Uveitis

Medicine Advances, EarlyView.
HLA‐B27‐associated acute anterior uveitis causes significant inflammation of the iris and anterior chamber, which disrupts normal parasympathetic control and results in increased sympathetic tone leading to pupil dilation (mydriasis). This finding can sometimes resemble herpetic uveitis, making a clinical context and careful evaluation crucial for ...

Brain Pericytes and Wnt/β‐Catenin Signaling Induce Functional Blood–Brain Barrier Phenotype in Human iPSC‐Derived Model

Small Methods, EarlyView.
This study shows that human iPSC‐derived endothelial cells acquire a functional blood–brain barrier phenotype when co‐cultured with brain pericytes and stimulated with CHIR‐99021, a Wnt/β‐catenin activator. This model recapitulates key barrier properties, inflammatory responses, and transcriptomic features of the native human BBB, offering new ...

Association of HLA-B27 Gene and Rheumatoid Arthritis: Analysis of Potential Role as a Predictive Biomarker

Kurdistan Journal of Applied Research
Rheumatoid arthritis (RA) is a predominant inflammatory arthritis in human. The function of HLA-B27 gene in other types of arthritis has been studied, however, its function in RA is unclear. This study investigated the relative expression of HLA-B27 gene

Differences in Cellular Clearing Mechanisms of Aggregates of Two Subtypes of HLA-B27

Frontiers in Immunology, 2022
Ankylosing spondylitis (AS) belongs to a group of diseases, called spondyloarthropathies (SpA), that are strongly associated with the genetic marker HLA-B27. AS is characterized by inflammation of joints and primarily affects the spine. Over 160 subtypes
