2. 1. Genetic Variation in Mhc Class II B in Atlantic Salmon: Evolutionary and Ecological Perspectives

   Author : Åsa Langefors; Biodiversitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; recombination; genetic variation; Mhc class II B; Atlantic salmon; evolution; population genetics; Animal ecology; Djurekologi;

   Abstract : The Major Histocompatibility Complex (Mhc) genes are crucial for the recognition of self and non-self peptides by the immune defence system. They are extremely variable in most studied vertebrate species. I have studied the extent and the importance of Mhc variation in Atlantic salmon (Salmo salar), mainly from the Baltic Sea. READ MORE

4. 2. European Black Grouse : MHC Genetic Diversity and Population Structure

   Author : Tanja Strand; Jacob Höglund; Helena Westerdahl; David S. Richardson; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Major Histocompatibility Complex; BLB; balancing selection; concerted evolution; bottleneck; fragmentation; 3 UTR; Biologi med inriktning mot populationsbiologi; Biology with specialization in Population Biology;

   Abstract : Black grouse Tetrao tetrix is a bird species composed of large, continuous as well as severely reduced and fragmented populations, making it an optimal species to investigate how genetic diversity is affected by habitat fragmentation. I have focused on genetic diversity in the Major Histocompatibility Complex (MHC) to measure the ability of the black grouse to respond to environmental changes. READ MORE

5. 3. Structural Basis of Immune Receptor Binding by Staphylococcal Superantigens

   Author : Karin Rödström; Medicinsk strukturbiologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Superantigen; X-ray Crystallography; T cell receptor; Major histocompatibility complex;

   Abstract : Superantigens (SAgs) are toxins capable of inducing a massive immune response, leading to severe disease. They are secreted by the bacteria Staphylococcus aureus and Streptococcus pyogenes, which produce the staphylococcal enterotoxins and streptococcal pyogenic exotoxins, respectively. READ MORE

6. 4. Immunoecology of the Great Snipe (Gallinago media) : Mate Choice, MHC Variation, and Humoral Immunocompetence in a Lekking Bird

   Author : Robert Ekblom; Jacob Höglund; Mats Grahn; Scott V. Edwards; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biology; Behaviour; Major histocompatibility complex class II B; Sexual selection; Evolution; Leks; Biologi; Biology; Biologi;

   Abstract : At the centre of the vertebrate immune system is a group of proteins called MHC (major histocompatibility complex) molecules. These function in self – non self recognition and activation of the immune defence against intruding parasites and pathogens. READ MORE

7. 5. MHC and Transgenic Mice. A study into polymorphism and function of class I and class II molecules

   Author : Mikael Vestberg; Immunologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MHC rat mouse transgenic autoimmunity collagen peptide; Clinical biology; Klinisk biologi;

   Abstract : Transplantation antigens encoded in the major histocompatibility complex (MHC) bind peptides and present them to T cells. We showed that mouse T cells expressing transgenic human CD8 can recognise human MHC class I. READ MORE
