background: the study aimed to examine the association between human leukocyte antigen (hla) class ii allele frequencies and breast cancer in iranian women. methods: a total of 100 patients with pathologically proven breast cancer who referred to cancer institute were randomly selected and compared with a group of age matched healthy blood donors (n = 80). hla class ii alleles were determined b...

common variable immunodeficiency (cvid) is a heterogeneous heritable disease characterized by arrest in b cell differentiation. an association between cvid and two hla haplotypes, haplotype i (hla-a1, hla-b8, hla-dr3) and haplotype ii (hla-a29, hla-b44, hladr7)has been previously documented. in the present study, we have attempted to find an association between susceptibility to cvid and hla cl...

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 ...

recurrent aphthous stomatitis (ras) is known as the most common chronic disease of the oral cavity, which affects a range of 5-25% of the population. ras appears to be associated with some human leukocyte antigen (hla) class ii alleles and haplotypes. this study attempts to survey the distribution of hla-drb and -dqb alleles among iranian ras patients and healthy controls. in order to evaluate ...

host genetic factors play a central role in determining the clinical phenotype of human diseases. association between two polymorphic loci in human genome, human leukocyte antigen (hla) and killer cell immunoglobulin-like receptors (kirs), and genetically complex infectious disease, particularly those of viral etiology, have been historically elusive. hence, defining the influence of genetic di...

hepatitis b virus (hbv) infection and its sequelae such as cirrhosis and hepatocellular carcinoma has remained a serious public health problem throughout the world. the who strategy for effective control of hbv infection and its complications is mass vaccination of neonates and children within the framework of expanded programme on immunization (epi). vaccination with hepatitis b surface antige...

objective: hla-g is a nonclassical major histocompatibility complex antigen and is expressed as seven isoforms, including four membrane bound (hla-g1 to –g4) and three soluble (hla-g5 to –g7) forms. the pattern of selective expression of hla-g transcripts in tissues shows the existence of a tight transcriptional control on the gene expression. it has been revealed that cytokines including inter...

background: pediatric bronchial asthma is associated with considerable morbidity. the study was carried out to examine the association of human leukocyte antigen (hla)- class ii with the disease as we found no similar study on asian indian population. objective: to define the hla-class ii antigens in asian indian pediatric patients with asthma. methods: a total of 103 children with asthma and 1...
