The cell biology of major histocompatibility complex class I assembly: towards a molecular understanding.
Major histocompatibility complex class I (MHC I) proteins protect the host from intracellular pathogens and cellular abnormalities through the binding of peptide fragments derived primarily from intracellular proteins. These peptide-MHC complexes are displayed at the cell surface for inspection by cytotoxic T lymphocytes. Here we reveal how MHC I molecules achieve this feat in the face of numer...
متن کاملThe major histocompatibility complex.
The major histocompatibility complex on the sixth chromosome controls expression of a complex series of cell surface antigens which comprise the human leukocyte antigen (HLA) system. These markers, beyond their importance in human organ transplantation, have been demonstrated to occur with an increased prevalence in certain disease states. The group of conditions showing the closest association...
متن کاملEvolution of the major histocompatibility complex: molecular cloning of major histocompatibility complex class I from the amphibian Xenopus.
Class I major histocompatibility complex (MHC) cDNA clones have been isolated from an expression library derived from mRNA of an MHC homozygous Xenopus laevis. The nucleotide and predicted amino acid sequences show definite similarity to MHC class I molecules of higher vertebrates. The immunoglobulin-like alpha-3 domain is more similar to the immunoglobulin-like domains of mammalian class II be...
متن کاملMajor Histocompatibility Complex (MHC) Markers in Conservation Biology
Human impacts through habitat destruction, introduction of invasive species and climate change are increasing the number of species threatened with extinction. Decreases in population size simultaneously lead to reductions in genetic diversity, ultimately reducing the ability of populations to adapt to a changing environment. In this way, loss of genetic polymorphism is linked with extinction r...
متن کاملPorcine major histocompatibility complex.
The major histocompatibility complex in swine (swine leucocyte antigen: SLA) is located on chromosome 7 with the class I and class III regions separated by the centromere from the class II region. The overall molecular organisation of the class I and III regions is well known, but further research is needed to establish that of the class II region. Approximately sixty genes have been characteri...
