Major Histocompatibility Complex, Class I, B

چکیده
Description The genes of the Human Leukocyte Antigen (HLA) system reside on chromosome 6, and code for cellsurface proteins that play a crucial role in the presentation of endogenic peptides to effector cells of the immune system. The HLA Class I protein molecule is a heterodimer, made up of two chains; a heavy one and a light one (beta 2 microglobulin). The HLA-B gene is one of the three HLA Class I heavy chain paralogues. The HLA Class I protein presents peptides from the lumen of the endoplasmic reticulum to T-cells, thereby effecting a cascade of immunologic reactions.

MMP3 -1171 5A/6A Promoter Polymorphism Affects Level of Serum Major Histocompatibility Complex Class Chain Related B in Breast Cancer Patients
Background and Aims: Involvement of matrix metalloproteinases 3 (MMP3) in breast cancer tumor progression and metastasis has been revealed. MMP3 -1171 5A/6A and 5A/5A polymorphisms in the gene promoter increase expression of the enzyme. The possible relationship of these polymorphisms and serum levels of major histocompatibility complex class I chain-related protein A and B (MICA/B) in br...

Background and purpose: Major histocompatibility antigens are the most polymorphic components of the immune system. The purpose of this study was to determine the frequency of human leukocyte antigens (HLA) in a population in Mazandaran province, Iran. Materials and methods: In a cross sectional study, peripheral blood samples were obtained from 550 people in Immunogenetics Research Center af...
متن کاملIdentification and characterization of major histocompatibility complex class IIB alleles from three species of European ranid frogs
Immune genes of the major histocompatibility complex (MHC) are among the most polymorphic genes in the vertebrate genome. Due to their polymorphic nature, they are often used to assess the adaptive genetic variability of natural populations. This study describes the first molecular characterization of 13 partial MHC class IIB sequences from three European ranid frogs. The utility of previously...
متن کاملA Case of Probable MHC Class II Deficiency with Disseminated BCGitis
Major histocompatibility complex (MHC) class II deficiency is a primary immunodeficiency disease characterized by abnormality of MHC class II molecules surface expression on peripheral blood lymphocytes and monocytes. Clinical manifestations include extreme susceptibility to viral, bacterial, and fungal infections but the immunodeficiency is not as severe as SCID (severe combined immunodeficien...
متن کاملTransfer of GRP94(Gp96)-associated peptides onto endosomal MHC class I molecules.
GRP94 (gp96)-associated peptides can elicit cellular immune responses, an activity thought to reflect the presence of a cell surface receptor (CD91) on antigen-presenting cells that mediates GRP94 internalization and trafficking to an amenable site for peptide transfer to major histocompatibility complex class I molecules. We report that GRP94 internalized by receptor-mediated endocytosis is tr...
متن کاملFrequencies of HLA-A, B and DRB1 alleles in a large normal population living in the city of Mashhad, Northeastern Iran
Objective(s): The population in Iran is a genetic admixture of the ancestral Aryan and other populations neighboring Iran. Different ethnic groups in Iran show wide regional distributions for many human leukocyte antigen (HLA) alleles. Therefore, it is necessary and sensible to study the differences in HLA allele distribution in different area. We studied the HLA class I and II allele frequenci...
