1. 21. Plant Membrane Proteomics - using isolated membranes and proteins to compare and quantify subproteomes

   Författare :Katja Bernfur; Biokemi och Strukturbiologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mass spectrometry; quantification; proteomics; metabolic labeling; plasma membrane;

   Sammanfattning : Membrane proteins are particularly important to characterize, since they are involved in cellular processes of utmost importance in control and regulation of cells, such as transport across membranes, signal transduction and photosynthesis. The word "proteome" means all proteins expressed by a e.g. LÄS MER

3. 22. HLA class I maturation - in the presence and absence of tapasin

   Författare :Linda Geironson Ulfsson; Biologiska institutionen; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Human leukocyte antigen class I (HLA-I) molecules are present on all nucleated cells and present the cell content to cytotoxic T lymphocytes in the form of peptides. Maturation of HLA-I occurs in the endoplasmic reticulum and results in stable peptide-HLA-I complexes, in the presence of proper quality control. LÄS MER

4. 23. Peptide-tagged proteins in aqueous two-phase systems

   Författare :Anna Nilsson; Biokemi och Strukturbiologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Metabolism; Biokemi; metabolism; Biochemistry; green fluorescent protein; cutinase; tryptophan; Aqueous two-phase system; peptide-tagged protein;

   Sammanfattning : This thesis deals with proteins containing peptide tags for improved partitioning in aqueous two-phase systems. Qualitatively the peptide-tagged protein partitioning could be predicted from peptide data, i.e. partitioning trends found for peptides were also found for the peptide-tagged proteins. LÄS MER

5. 24. Helicobacter pylori cell surface interactions with glycosaminoglycans. Identification and characterisation of proteins binding to heparin/heparan sulphate

   Författare :Meeme Utt; Celiaki och diabetes; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; SELDI-TOF MS; bioinformatics; proteomics; immunoblotting; 2-DE; biosensor; heparan sulphate; heparin; binding; Helicobacter pylori; cell surface; bakteriologi; Mikrobiologi; mycology; bacteriology; Microbiology; mykologi; virologi; virology;

   Sammanfattning : Helicobacter pylori is a gastric pathogen which cause chronic type B gastritis and peptic ulcer disease. H. pylori produces virulence factors such as urease, vacuolating cytotoxin VacA, cag pathogenicity island-associated proteins, flagella and adhesins. LÄS MER

7. 25. Eco-immunological studies of innate immunity in Mallards (Anas platyrhynchos)

   Författare :Anu S. Helin; Jonas Waldenström; Edwin Veldhuizen; Linnéuniversitetet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Avian β-defensins AvBDs ; Avian gene expression; Host-pathogen interactions; Innate immunity; Mallard Anas platyrhynchos ; Myxovirus resistance gene Mx ; Retinoic acid inducible gene 1 RIG-I ; Avian β-defensins AvBD ; Genuttryck; Gräsand Anas platyrhynchos ; Immunförsvar; Immungener; Myxovirus resistant gene Mx ; Patogen; Retinoic acid inducible gene 1 RIG-I ; Ecology; Ekologi;

   Sammanfattning : This thesis comprises two sections, both of which explore eco-immunology of the innate immune system of mallards (Anas platyrhynchos). The innate immune system serves a pivotal role as the first line of defense against invading pathogens, and is comprised of physical and chemical barriers. LÄS MER
