  1. 11. On the regulation of immune responses to dietary and self antigens

    Författare :Susanne Lindgren; Göteborgs universitet; []
    Nyckelord :Tolerance; regulatory T cells; self antigens; oral tolerance; dietary antigens; intestinal epithelial cells; exosomes; Staphylococcus aureus enterotoxin A;

    Sammanfattning : Regulatory mechanisms are necessary to avoid the misdirected aggressive immune responses responsible for the pathology seen in autoimmunity and allergy. Thymic-derived CD4+CD25+ regulatory T cells are indispensible for this regulation. We investigated if CD4+CD25+ Treg prevents auto-reactive responses in adult peripheral blood and cord blood.

  3. 12. CRISPRi/a for investigating yeast tolerance to inhibitors in lignocellulosic hydrolysates

    Författare :Ibai Lenitz Etxaburu; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lignocellulosic hydrolysates; ChIP-exo; Screening; Biosensor; Formic acid; Competitive growth assay; Yeast; Tolerance; CRISPRi a; Acetic acid;

    Sammanfattning : Saccharomyces cerevisiae has immense potential as a cell factory in various biotechnological processes where biomass from agricultural industry residues is used as feedstock. Nonetheless, the inhibitors released during the pretreatment of the biomass makes lignocellulosic hydrolysates a challenging substrate for microorganisms. LÄS MER

  4. 13. Managing Geometrical Variation in Complex Assemblies through Visualization and Tolerance Allocation

    Författare :Johan Lööf; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tolerance analysis; and motion envelope.; variation simulation; tolerance allocation; visualization;

    Sammanfattning : To stay competitive in the market today, manufacturing companies have to shorten their time to market. This implies that time also has to be saved during the product development phase. This thesis will mainly focus on how to be more efficient in the detail design phase through different design activities. LÄS MER

  5. 14. Tolerance Mechanisms in Collagen-Induced Arthritis an Animal Model of Rheumatoid Arthritis

    Författare :Alexandra Treschow; Immunologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Skeleton; Tolerance; Regulation; IFN-beta; Macrophages; Immunology; serology; transplantation; Immunologi; serologi; Arthritis; Collage; rheumatology locomotion; muscle system; Skelett; muskelsystem; reumatologi;

    Sammanfattning : Collagen-induced arthritis (CIA) is one of the most commonly used animal models for Rheumatoid arthritis (RA). CIA is induced in susceptible mouse strains after immunization with heterologous type II collagen (CII). In mice of the H-2q haplotype rat CII (rCII) is used whereas in mice of the H-2r haplotype bovine CII is utilized. LÄS MER

  7. 15. Impacts of Antifouling Compounds on Photosynthesis, Community Tolerance and psbA Genes in Marine Periphyton

    Författare :Martin Eriksson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PICT; antifouling; periphyton; photosynthesis; D1; psbA; tolerance; resistance; periphyton;

    Sammanfattning : Toxicants can act as selective pressures in the environment, eliminating sensitive genotypes or species and favouring tolerant ones. Such toxicant-induced selection can be detected in natura... LÄS MER
