HLA-B27 is the most researched HLA-B allele due to its high relationship with spondyloarthropathies. Although it is not apparent how HLA-B27 promotes disease, theories exist and can be divided between antigen-dependent and antigen-independent categories.

2023年7月4日 · Acute anterior uveitis (AAU) has been strongly linked with HLA-B27 and is the most common cause of non-infectious uveitis. HLA-B27 associated uveitis is more common in younger patients with a typical age range of 20 to 40. Young patients presenting with acute anterior uveitis should be evaluated for systemic symptoms of spondyloarthritis.

One gene, HLA-B27, is strongly associated with a big family of rheumatic diseases called spondyloarthropathies. It includes: These diseases mainly cause pain, stiffness and inflammation in the spine, hip joints and entheses – places where ligaments and tendons attach to bones.

2018年6月5日 · During the course of a workup for possible autoimmune arthritis or autoimmune back disease, your rheumatologist may order something called a HLA-B27 test. So what does a positive HLA-B27 mean? HLA-B27 is a genetic test. The majority of people who have a positive HLA-B27 are perfectly healthy.

2018年11月13日 · The human leukocyte antigen B27 (HLA-B27) blood test is used to help diagnose autoimmune disorders. Learn more about what to expect during the test.

The human lymphocyte antigen B27 (HLA B27) is a member of the HLA class I family of genes in the major histocompatibility complex whose name goes back to its discovery in studies of transplanted tissue compatibility. Its prevalence in the mid-European population is about 8%.

2018年2月5日 · As a gene that codes for a protein that presents antigen to induce an immune response and that also regulates positive and negative selection of T cells in the thymus, HLA-B27 almost certainly does have an effect on normal human microbial flora.

2014年1月1日 · Here, we focus on the biology of HLA-B27 from the genetics to the biochemistry and to the structural/dynamical properties of B27:peptide complexes as obtained from atomistic molecular dynamics simulation. Overall, the results point at the antigen presentation as the key event in the disease pathogenesis.

El antígeno HLA B27 está asociado con una gran cantidad de enfermedades autoinmunitarias. Veremos las causas, qué significa tener HLA-27 positivo, etc. Ver todos los resultados

Es un examen de sangre para buscar una proteína específica que se encuentra en la superficie de los glóbulos blancos. Dicha proteína se denomina antígeno leucocitario humano B27 (HLA-B27).
