  1. 16. Regulation of the pro-apoptotic protein Bim by T cell receptor triggering in human T cells

    Författare :Elena Sandalova; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Bim; Apoptosis; Mitochondria; CTLs; AICD; TCR activation;

    Sammanfattning : Bim is a significant pro-apoptotic member of Bcl-2 family of proteins; it is proved to be an important regulator of apoptosis: over the years it has been shown to play a pivotal role for the development and maintenance of homeostasis in many cellular systems and tissues. The Bcl-2 family of proteins is a group of key regulators of the mitochondrial, or intrinsic, pathway of apoptosis. LÄS MER

  3. 17. Elicitor-induced formation of secondary products in plant cell cultures. Production of benzophenanthridine alkaloids in Eschscholtzia californica Cham. and hydroxycinnamic acid tyramides in Nicotiana glutinosa L

    Författare :Mirza Villegas; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; macarpine; chelerythrine; sanguinarine; benzophenanthridine alkaloids; Nicotiana glutinosa; Eschscholtzia californica; secondary metabolites; Key words elicitors; immobilisation; hydroxycinnamoyltyramides.; Plant biochemistry; Växtbiokemi;

    Sammanfattning : Biotic and abiotic elicitors induce biosynthesis of secondary metabolites (phytoalexins) as a defense against pathogenic organisms in plants. The use of cell suspension cultures in combination with elicitors offer excellent experimental model systems for studies on various elicitor-induced responses of plant tissues. LÄS MER

  4. 18. Regulation of Polyamine Analogue-Induced Apoptosis in Human Breast Cancer Cells

    Författare :Martina Holst; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cancer; Animal physiology; Djurfysiologi; Pharmacological sciences; pharmacognosy; pharmacy; onkologi; Cytologi; cancerology; oncology; Cytochrome c; Cytology; Bcl-2; Mitochondrial respiration; Apoptosis; Human breast cancer cells; toxicology; Farmakologi; farmakognosi; farmaci; toxikologi; Social medicine; Socialmedicin; samhällsmedicin; Mitochondria; Polyamine analogues;

    Sammanfattning : Apoptosis is a defined process for cells to commit suicide through a set of biochemical and morphological cell changes. Activated apoptotic signals converge on the mitochondria, leading to permeabilization of mitochondrial membranes and release of different apoptosis regulatory proteins into the cytosol. LÄS MER

  5. 19. Effects of Pulsed Electric Fields on Plant Tissue

    Författare :Yongyut Chalermchat; Livsmedelsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Technological sciences; Electropermeabilization; Pulsed electric fields; Plant Tissue; Teknik;

    Sammanfattning : The interaction between biological cells and external electric fields has been of interest by scientists for several decades. Exposure of the cells to electric fields leads to various kinds of biophysical and biochemical responses. These responses can be used to characterize cell properties and/or to manipulate cell characteristics. LÄS MER

  7. 20. Deep Candida infections. Serology for laboratory diagnosis and antifungal activity of lactoferrin derived fragments

    Författare :Nahid Kondori; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Deep Candida infections (DCI) in patients who are immunocompromised or in intensive care units present both diagnostic and therapeutic problems. Serological tests for diagnosis of invasive fungal infections are used with varying results. Moreover, long term therapies with antifungal agents have led to the emergence of resistant Candida strains. LÄS MER
