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...

background: hla-g gene contains 15 alleles including a null allele, hla-g*0105n. previous studies have shown that hla-g*0105n does not encode the complete hla-g1 or hla-g5 isoforms but encodes a functional hla-g protein with the ability to in-hibit nk cell cytolysis. thus, although the biological functions of hla-g1 and hla-g5 proteins are abrogated, other isoforms such as hla-g2 can replace th...

Background: The origin and function of human leukocyte antigen (HLA) class I molecules on platelets are still highly arguable. Given the differences in the results of the previous studies in this regard, the lack of research in recent years, and the clinical importance of HLA class I molecules, the absorption capacity of platelets for soluble HLA class I molecules was studied in this investigat...

introduction: the major histocompatibility complex (mhc) is a group of cell surface proteins that are essential for recognizing foreign molecules in human and other mammals. the physiologic function of mhc molecules is the presentation of peptides to t cells. in this study, we evaluated the purification of a class ii mhc molecule (hla-dr) from a human burkitt′s lymphoma cell line; daudi. materi...

Background: Human leukocyte antigen (HLA) class II has shown potential in determining prognosis, understanding medication reactions, and predicting onset of Graves’ disease. The aim this study is to further investigate the association between disease HLA II, specifically HLA-DQ HLA-DR, via meta-analysis find HLAs that can be examined for prognostic reasons.

The pathogenesis of classical Hodgkin lymphoma (cHL) involves environmental and genetic factors. To explore the role of the human leukocyte antigen (HLA) genes, we performed a case-control genotyping study in 338 Dutch cHL patients using a PCR-based sequence-specific oligonucleotide probe (SSOP) hybridization approach. The allele frequencies were compared to HLA typings of more than 6,000 contr...

BACKGROUND Pulmonary tuberculosis (PT) is one of the endemic diseases in Iraq, and among the suggested predisposing factors are alleles of the human leukocyte antigen (HLA) system. We sought to investigate the association between HLA-class I (A and B) and -class II (DR and DQ) alleles in a sample of PT Iraqi patients. METHODS lymphocytes of 105 PT patients and 40 controls were phenotyped for ...
