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-B27 modulates the phosphorylation of signal transducer and activator of transcription 1 (STAT-1) serine 727 residue and the localization of ST...
the human major histocompatibility complex (mhc) plays a crucial role in transplantation, transfusion, paternity test and assessment of susceptibility to some diseases associated with hla-b27. three of the most fashionable methods for determination of hla antigens in clinical and research laboratories are microlymphocytotoxicity (mlct), flowcytometry and polymerase chain reaction (pcr). the pur...
■ Acute anterior uveitis (AAU) accounts for 90% of all uveitis cases seen by the general ophthalmologist. ■ About half of all AAU cases are HLA-B27associated. ■ HLA-B27+ AAU represents a distinct clinical entity with important ocular and extraocular consequences. ■ The typical ocular phenotype of HLA-B27+ AAU is that of acute onset, unilateral inflammation of the iris and ciliary body, with a t...
INTRODUCTION Spondyloarthropathies are a heterogeneous group of rheumatic disorders that commonly present with axial skeleton or sacroiliac joints involvement. Ocular involvement like uveitis, iritis and conjunctivitis can be present in up to a third of the patients. Genetic factors play a part in the pathogenesis of spondyloarthropathies. Association with the HLA-B27 gene, especially that betw...
HLA-B27 transgenic rats are a model of spontaneous gastrointestinal inflammation associated with expression of human leukocyte antigen (HLA) B27 and beta(2)-microglobulin. Our goal was to investigate in vitro enteric nerve regulation and contractile activity in isolated longitudinal muscles from the jejunum and colon of HLA-B27 rats. Nontransgenic age-matched Fisher 344 rats were used as contro...

Inflammatory arthritis, tendinitis, and fasciitis after non-specific urethritis ("sexually acquired reactive arthritis" (SARA)) was studied prospectively in 531 men with non-specific urethritis, with particular reference to the frequency of isolation of Chlamydia trachomatis and the presence of HLA-B27. Satisfactory cultures were obtained from the urethral swabs from 384 patients; and HLA typin...
We describe a patient with Noonan syndrome who presented with Human Leukocyte Antigen B27-associated recurrent acute anterior uveitis and manifestations of congenital fibrosis of the extraocular muscles, which has not been reported before.
Psoriatic arthritis is a chronic destructive joint disease. About 40% of psoriatic arthritis patients are positive for human lymphocyte antigens (HLA)-B27. This study investigated the relationship between HLA-B27 and clinical manifestations and prognosis in psoriatic arthritis patients. Demographic, clinical, and laboratory data were analyzed from 41 psoriatic arthritis patients with regular fo...
