Background: Autoimmune blistering diseases (AIBDs) are a group of rare acquired skin diseases, which divided into five major subtypes based on the clinical appearance and pathology: pemphigus bullous pemphigoid (BP), epidermolysis bullosa acquisita (EBA), dermatitis herpetiformis (DH) Linear IgA dermatosis (LigA). Current understanding has been greatly increased by genetic investigations mainly...
The Major Histocompatibility Complex (MHC, 6p21) codes for traditional HLA and other host response related genes. The polymorphic HLA-DRB1 gene in MHC Class II has been associated with several complex diseases. In this study we focus on MHC haplotype structures in the Finnish population. We explore the variability of extended HLA-DRB1 haplotypes in relation to the other traditional HLA genes an...
Rheumatoid arthritis (RA) is strongly associated with the human leukocyte antigen (HLA)-DRB1 locus that possesses the shared susceptibility epitope (SE) and the citrullination of self-antigens. We show how citrullinated aggrecan and vimentin epitopes bind to HLA-DRB1*04:01/04. Citrulline was accommodated within the electropositive P4 pocket of HLA-DRB1*04:01/04, whereas the electronegative P4 p...
BACKGROUND Knowledge of allele and haplotype frequencies of the human leukocyte antigen (HLA) system is important in the search for unrelated bone marrow donors. The Brazilian population is very heterogeneous and the HLA system is highly informative of populations because of the high level of polymorphisms. AIM The aim of this study was to characterize the immunogenetic profile of ethnic grou...
This is the first report of high-resolution human leukocyte antigen (HLA) typing in four indigenous groups in Malaysia. A total of 99 normal, healthy participants representing the Negrito (Jehai and Kensiu), Proto-Malay (Temuan) and a native group of Borneo (Bidayuh) were typed for HLA-A, -B, -DRB1 and -DQB1 genes using sequence-based typing. Eleven HLA-A, 26 HLA-B, 16 HLA-DRB1 and 14 HLA-DQB1 ...
Immune disorders may play an important role in the pathogenesis of Parkinson's disease (PD). Recently, polymorphisms in the HLA-DR region have been found to be associated with sporadic PD in European ancestry populations. However, polymorphisms in the HLA complex are highly variable with ethnic and geographic origin. To explore the relationships between polymorphisms of the HLA-DR region and sp...
هدف: تأثیر آلل ها، ژنوتیپ ها و هاپلوتایپ های hla–drb1 و hla–dqb1 بر سن شروع بیماری دیابت نوع یک در ایران بررسی شد. مواد و روش ها: آلل های hla–drb1, -dqb1 در 105 بیمار دیابتی نوع یک و 100 فرد سالم از قومیتهای مختلف، با سن شروع بیماری مقایسه شد. بیماران براساس سن شروع بیماری به 4 گروه سنی (1-5، 6- 10، 11-15، 16- 20 سالگی) طبقه بندی شدند و فراوانی هر یک از آلل ها، ژنوتیپ ها و هاپلوتایپ های مستعد...
Background: Human leukocyte antigen (HLA) complex is a gene family involved in antigen presentation associated with protection or susceptibility to inflammatory, infectious and autoimmune diseases. Atherosclerosis is a chronic inflammatory disease in which HLA molecules play a role in the initiation and development of the disease through presentation of self or foreign antigens to T cells. Obje...
Background: Human leukocyte antigens (HLAs) are found to be significant genetic factors concerning the susceptibility of an individual to certain diseases. Objective: To determine the association between variants of class I (A and B) and class II (DRB1) HLA alleles and chronic renal failure (CRF), compared with healthy controls, in Yemen. Methods: A case-control study in the Urology and Nephrol...
The association of HLA class II genes with ulcerative colitis (UC) as an autoimmune disease has been investigated for several years. However, factors responsible for genetic predisposition of this disease have so far not been clearly understood. In this study, for the first time, we aimed to investigate the association between HLA-DRB1 types and UC in the population of Kerman, a city southeast ...
