  1. 1. Gene conversion of the mouse MHC class II

    Author : Kari Högstrand; Ulf Gyllensten; Stockholms universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MHC; H2; gene conversion; evolution; polymorphism; Immunology; Immunologi; immunologi; Immunology;

    Abstract : The major histocompatibility complex (MHC) is the most polymorphic vertebrate gene loci known to exist. Gene products of the MHC are responsible for presentation of antigen derived peptides to T cells of the immune system, which thereby become activated and involved in the elimination of particles recognised as non-self.

  2. 2. The quality control of MHC class I antigen presentation

    Author : Kajsa M Paulsson; Antigen presentation; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; chaperone; assembly; COPI; antigenic peptide; TAP; MHC; tapasin; Immunology; serology; transplantation; Immunologi; serologi;

    Abstract : Major histocompatibility complex (MHC) class I molecules present antigenic peptides to CD8+ T cells. The peptides are generated by proteasomes in the cytosol, then translocated across the membrane of the endoplasmic reticulum (ER) by the transporter associated with antigen processing (TAP).

  3. 3. MHC polymorphism in a songbird : Fitness, mate choice, and sexual conflict

    Author : Jacob Roved; MEMEG; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Major histocompatibility complex; MHC diversity; MHC haplotypes; sexually antagonistic selection; costs of immune responses; adaptive immunity; great reed warbler; songbird;

    Abstract : Sex differences in immune responses have been observed across a wide range of animal species, with the generaltendency that males have weaker immune responses than females. These differences are at least partly caused by immune-regulating effects of sex hormones, and have been associated with an increased prevalence of autoimmune disorders in females and with a general tendency for males to be parasitized more often than females.

  4. 4. Design strategies for new drugs targeting multicomponent systems : focusing on class II MHC proteins and acetylcholinesterase

    Author : Cecilia Lindgren; Anna Linusson; Antti Poso; Umeå universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; acetylcholinesterase; class II MHC protein; drug design; molecular dynamics simulation; multicomponent system; nerve agent; oxime; quantitative structure-activity relationship; reactivator; rheumatoid arthritis; statistical molecular design; T-cell receptor;

    Abstract : The field of medicinal chemistry is constantly evolving. Aided by advances within techniques as well as knowledge of biological systems, increasingly complex targets and drugs can be considered. READ MORE

  5. 5. Avian MHC: variation and selection in the wild

    Author : Helena Westerdahl; MEMEG; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; polymorphism; balancing selection; cDNA; avian malaria; great reed warbler; Djurekologi; bird; Animal ecology; immune defence; MHC class II; Major Histocompatibility Complex; MHC class I;

    Abstract : In vertebrates the Major Histocompatibility Complex (MHC) plays a central role in the specific immune defence against various pathogens. Compared with other coding genes the MHC genes exhibit an extremely high level of polymorphism that is maintained by balancing selection. READ MORE
