Aim.To study the immunogenetic prerequisites of idiopathic recurrent spontaneous pregnancy losses in humans allo- and autoimmune genesis. Methods. PCR-SSP (polymerase chain reaction with sequence-specific primers). Results. A comprehensive analysis distribution frequency allelic variants HLA-DRB1, HLA-DQA1, HLA-DQB1 genes testifies to an increased risk a total homology 50 % or more couples pres...

Objective To explore genetic association between human leukocyte antigen (HLA) and neurodegenerative diseases investigate mechanisms behind the association. Background Pathophysiology of Alzheimer's disease (AD), Parkinson's (PD) amyotrophic lateral sclerosis (ALS) involves accumulation tau (neurofibrillary tangles) amyloid-ß-rich (amyloid plaques) aggregates in AD, a-synuclein-rich (Lewy bodie...

Abstract Background : Suicide is a complex phenomenon determined by the interaction of various risk factors. The Major Histocompatibility Complex most polymorphic gene cluster entire human genome, being linked to both regulation immune system and psychiatric diseases. aim this study was identify HLA-DQB1 DRB1 alleles genotypes susceptible influence suicidal behavior. Methods We explored associa...

objective: type 1 diabetes mellitus (t1d) is an autoimmune and multifactorial disorder. subsequent analysis on human leukocyte antigen ( hla) region shows that hla-drb1 and -dqb1 genes have the strongest association with t1d. in this study, for the first time, we investigated the influence of gender on the hla-drb1 and -dqb1 association with type 1 diabetes mellitus in iranian patients in order...

The major histocompatibility complex is directly involved in the immune response, and thus genes coding for its proteins are useful markers study of genetic diversity, susceptibility to disease (autoimmunity infections), transplant medicine, pharmacogenetics, among others. polymorphism system also allows researchers use it as a proxy population genetics analysis, such admixture structure. In or...

background and objective: the outcome of hepatitis b virus (hbv) infection may be influenced by host factors like human leukocyte antigen (hla). we have investigated hla-a and drb1 alleles in patients with persistent hepatitis b infection compared to subjects who had spontaneously recovered from hbv infection. to complete the findings of this study we performed another survey in certain hla all...

multiple sclerosis (ms) is an inflammatory demyelinating disease of the central nervous system. it is a clinically heterogeneous disorder especially in terms of disease severity. current investigations suggest that genes and gene-gene interactions not only influence on susceptibility to ms but also affect the disease severity. in this study, we investigated the contribution of the hladrb1*1501 ...

Multiple sclerosis (MS) is a complex trait in which alleles at or near the class II loci HLA-DRB1 and HLA-DQB1 contribute significantly to genetic risk. HLA-DRB1*15 and HLA-DRB1*17-bearing haplotypes and interactions at the HLA-DRB1 locus increase risk of MS but it has taken large samples to identify resistance HLA-DRB1 alleles. In this investigation of 7,093 individuals from 1,432 MS families,...

Background: Different studies have demonstrated that a small proportion of healthy individuals receiving the hepatitis B (HB) vaccine do not produce protective levels of anti-HB antibody, a phenomenon which could be linked to certain human leukocyte an-tigen (HLA) class-II alleles or haplotypes. Objectives: The present study was under-taken to determine the frequency of HLA class-II alleles in ...
