Frequency of Major Histocompatibility Antigens Class I in Mazandaran Province
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 کاملMajor Histocompatibility Complex, Class I, B
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 C...
متن کاملChicken major histocompatibility complex class I definition using antisera induced by cloned class I sequences.
Alloantisera directed against chicken class I MHC (BFIV) antigens were produced by using transfected cell lines expressing cloned BFIV sequences. The cloned BFIV sequences were from haplotypes *12, *13, and *21. Two laboratory-derived class I mutant sequences (BFIV13m126 and BFIV21m78) were developed to analyze cross-reactive epitopes and to induce specific alloantisera. Antisera were tested in...
متن کاملGeometry Dynamics of α-Helices in Different Class I Major Histocompatibility Complexes
MHC α-helices form the antigen-binding cleft and are of particular interest for immunological reactions. To monitor these helices in molecular dynamics simulations, we applied a parsimonious fragment-fitting method to trace the axes of the α-helices. Each resulting axis was fitted by polynomials in a least-squares sense and the curvature integral was computed. To find the appropriate polynomial...
متن کاملRedox-regulated export of the major histocompatibility complex class I-peptide complexes from the endoplasmic reticulum.
In contrast to the fairly well-characterized mechanism of assembly of MHC class I-peptide complexes, the disassembly mechanism by which peptide-loaded MHC class I molecules are released from the peptide-loading complex and exit the endoplasmic reticulum (ER) is poorly understood. Optimal peptide binding by MHC class I molecules is assumed to be sufficient for triggering exit of peptide-filled M...
