  3. 12. Studies on the immuno-modulating properties of the cholera toxin A1-based fusion protein CTA1-DD

    Författare :Anna Eriksson; Göteborgs universitet; []
    Nyckelord :adjuvant; cholera toxin; mucosa; targeting; B cell; immuno-modulation; vaccine;

    Sammanfattning : The present work was aimed at exploring the immuno-modulating properties of the novel cholera toxin (CT)-based vaccine adjuvant CTA1-DD, which combines the full enzymatic activity of the A1 subunit of CT with B cell targeting. We have studied the efficacy of the CTA1-DD adjuvant to enhance immune responses in mice after nasal administration. LÄS MER

  4. 13. Effects of toxin-producing phytoplankton on copepods: feeding, reproduction and implications to the fate of toxins

    Författare :Betina Kozlowsky-Suzuki; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ecology; Ekologi; GSH transferase; oocyte development; fate of toxins; toxin accumulation; toxic phytoplankton; copepods;

    Sammanfattning : Phytoplankton growth and loss rates are governed by several factors and in many cases, when growth control fails, algal blooms are established. Such blooms can be formed by different phytoplankton species and some of them have harmful impacts on marine ecosystems. LÄS MER

  5. 14. Lipooligosaccharide and Cytolethal distending toxin of Haemophilus ducreyi and antibody responses

    Författare :Annika Lundqvist; Göteborgs universitet; []
    Nyckelord :Haemophilus ducreyi; lipooligosaccharide; cytolethal distending toxin;

    Sammanfattning : The Gram-negative bacterium Haemophilus ducreyi causes chancroid, a sexually transmitted infection characterized by persistent ulcers on genitals. The disease is prevalent in developing countries and facilitates transmission and acquisition of HIV. LÄS MER

  7. 15. The Kluyveromyces lactis killer toxin is a transfer RNA endonuclease

    Författare :Jian Lu; Anders Byström; Leif Kirsebom; Umeå universitet; []
    Nyckelord :Molecular biology; K. lactis γ-toxin; tRNA endonuclease; modified nucleosides; 5-methoxycarbonylmethyl-2-thiouridine; 5-methylaminomethyl-2-thiouridine; anticodon stem loop; Molekylärbiologi; molekylärbiologi; Molecular Biology;

    Sammanfattning : Killer strains of the yeast Kluyveromyces lactis secrete a heterotrimeric protein toxin (zymocin) to inhibit the growth of sensitive yeasts. The cytotoxicity of zymocin resides in the γ subunit (γ-toxin), however the mechanism of cytotoxicity caused by γ-toxin was previously unknown. LÄS MER
