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...

HLA (Human Leukocyte Antigen) gene is located on chromosome 6’s short arm, including several loci. genotyping necessary for transplantation, especially in hematopoietic stem cell transplantation. A cross-sectional study to determine the frequency of HLA-A, HLA-B, and HLA-DRB1 alleles 122 patients admitted National Children’s Hospital Hematopoietic transplantation from year between 2010 2020. Th...

Background: HLA-G, as a tolerogenic molecule, expressed in cytotrophoblast cells and playing an important role in the suppression of the immune response in maternal decidua. Today Interaction of the extracellular domains of HLA-G protein with cell receptors of immune system, including CD8, LILRB1, LILRB2 and killer cell immunoglobulin-like receptor KIR2DL4, was well known. Materials and Methods...

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...

To investigate the human leukocyte antigen (HLA) association with anti-synthetase syndrome (ASSD). We conducted largest immunogenetic HLA-DRB1 and HLA-B study to date in a homogeneous cohort of 168 Caucasian patients ASSD 486 ethnically matched healthy controls by sequencing-based-typing. A statistically significant increase HLA-DRB1*03:01 HLA-B*08:01 alleles compared was disclosed (26.2% versu...
