  2. 21. Immunocytochemical visualization of cathepsin D during oxidative stress

    Author : Karin Roberg; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : Cathepsin D is the major aspartic protease in lysosomes, and it is found in almost all animal cells. In the present studies, a pre-embedding immunocytochemical method was used to visualize cathepsin D in cultured cells. The protein can be detected at both light and electron microscopic levels by neutral-pH silver enhancement of ultrasmall (0. READ MORE

  4. 22. 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

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

    Abstract : 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. READ MORE

  5. 23. The role of mast cell proteases in allergic disease and apoptosis

    Author : Ida Waern; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Mast cells (MCs) are key effector cells in allergic reactions, through the release of a wide variety of granule-stored and de novo synthesized inflammatory mediators. The MC secretory granules contain exceedingly high levels of serglycin proteoglycan and the heparin-binding proteases chymase, tryptase and carboxypeptidase A. READ MORE

  6. 24. Bacteria-host cell interactions : Studies on initial colonization, antimicrobial peptides, and biofilms

    Author : Gabriela Wassing; Ann-Beth Jonsson; Elena Vikström; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Neisseria meningitidis; Lactobacillus; host responses; EGR1; antimicrobial peptides; hBD2; A20; biofilm; molekylär biovetenskap; Molecular Bioscience;

    Abstract : The obligate human pathogen Neisseria meningitidis asymptomatically colonizes the upper respiratory tract, but crossing of the epithelial barrier can cause life-threatening meningitis and/or sepsis. N. READ MORE

  7. 25. Apoptotic mechanisms in the neonatal brain following hypoxia-ischemia

    Author : Ylva Carlsson; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; hypoxia-ischemia brain caspase-2 cyclophilin D MLK neonatal.;

    Abstract : Neonatal encephalopathy is often perinatally acquired and caused by hypoxia-ischemia (HI). Brain injury develops with a delay, over 12-48 hours, after the insult. Hypothermia, an established neuroprotective treatment, saves 1 infant in 9 from neurological deficits suggesting that there is room for further improvement. READ MORE
