Association of MHC and rheumatoid arthritis: HLA-DR4 and rheumatoid arthritis - studies in mice and men
نویسندگان
چکیده
Inherited susceptibility to rheumatoid arthritis (RA) is associated with the DRB1 genes encoding the human leukocyte antigen (HLA)-DR4 and HLA-DR1 molecules. Transgenic mice expressing these major histocompatibility complex (MHC) class II molecules have been developed to generate humanized models for RA. The relevance of these models for understanding RA will be discussed.

بررسی ارتباط HLA-DR4 و ساب تایپ‌های آن با ابتلا به آرتریت روماتوئید
Background: There are several evidences that genetic factors besides environmental triggers have important role in initiating the rheumatoid arthritis (RA). The aim of this study was to investigate the association of rheumatoid arthritis with different subtypes of HLA DR4 in Iranian patients. Methods: In an un-matched case control study, 110 rheumatoid arthritis patients (case) and 56 knee ost...
متن کاملAssociation of MHC and rheumatoid arthritis: Association of RA with HLA-DR4 - the role of repertoire selection
Most patients with rheumatoid arthritis (RA) express HLA-DR4, HLA-DR1 or HLA-DR10. These alleles share a common amino acid motif in their third hypervariable regions: the shared epitope. In normals and patients with RA, HLA-DR genes exert a major influence on the CD4 alpha beta T-cell repertoire, as shown by studies of AV and BV gene usage and by BV BJ gene usage by peripheral blood CD4 alpha b...
متن کاملIdentification of an altered peptide ligand based on the endogenously presented, rheumatoid arthritis-associated, human cartilage glycoprotein-39(263–275) epitope: an MHC anchor variant peptide for immune modulation
We sought to identify an altered peptide ligand (APL) based on the endogenously expressed synovial auto-epitope of human cartilage glycoprotein-39 (HC gp-39) for modulation of cognate, HLA-DR4-restricted T cells. For this purpose we employed a panel of well-characterized T cell hybridomas generated from HC gp-39-immunized HLA-DR4 transgenic mice. The hybridomas all respond to the HC gp-39(263-2...
متن کاملChinese with rheumatoid arthritis
Accepted for publication 15 March 1993 Abstract Objectives-Several studies have suggested that genetic predisposition to rheumatoid arthritis may be related to the presence of specific polymorphic HLA sequences that are often associated with HLA-DR4 haplotypes. This study was performed to determine if an association exists between Chinese with rheumatoid arthritis and a particular HLA-DR, or DQ...
متن کاملAssociation of MHC and rheumatoid arthritis: Regulatory role of HLA class II molecules in animal models of RA - studies on transgenic/knockout mice
Human leucocyte antigen (HLA) class II molecules have been shown to be associated with predisposition to rheumatoid arthritis (RA). We generated HLA-DR and DQ transgenic mice that lacked endogenous class II molecules to study the interaction between the DR and DQ molecules and define the immunologic mechanisms in rheumatoid arthritis. Using collagen-induced arthritis (CIA) as an experimental mo...
