  1. 1. Host-bacteria interactions : Host cell responses and bacterial pathogenesis

    Författare :Nele de Klerk; Ann-Beth Jonsson; Teresa Frisan; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Host-bacteria interaction; Helicobacter pylori; Neisseria gonorrhoeae; Lactobacillus; Epithelial cells; Macrophages; EGR1; Amphiregulin; SabA; molekylär biovetenskap; Molecular Bioscience;

    Sammanfattning : Helicobacter pylori colonizes the human stomach, where it causes gastritis that may develop into peptic ulcer disease or cancer when left untreated. Neisseria gonorrhoeae colonizes the urogenital tract and causes the sexually transmitted disease gonorrhea. LÄS MER

  3. 2. Ecology and evolution in a host-parasitoid system : Host search, immune responses and parasitoid virulence

    Författare :Lisa Fors; Peter Hambäck; Wertheim Bregje; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Host-parasitoid interactions; Plant-herbivore interactions; Host search; Volatiles; Pheromones; Geographic variation; Cellular defence; Melanisation; Encapsulation; Asecodes; Galerucella; Plant Ecology; växtekologi;

    Sammanfattning : In host-parasitoid systems, there is a continuous coevolutionary arms race where each species imposes a strong selection pressure on the other. The host needs to develop defence strategies in order to escape parasitism and the parasitoid must evolve counter-defence strategies in order to overcome the host’s immune defence and successfully reproduce.

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

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

    Sammanfattning : 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. LÄS MER

  5. 4. Host cell responses to Helicobacter pylori secreted factors

    Författare :Raquel Garcia Lobato Tavares; Sushil Kumar Pathak; Åsa Sjöling; Stockholms universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Helicobacter pylori; Secreted proteins; Host cell responses; Macrophages; Apoptosis; Pro-inflammatory cytokines; MAPKs; molekylär biovetenskap; Molecular Bioscience;

    Sammanfattning : The infection of the human gastric mucosa by the bacterium Helicobacter pylori can lead to the development of gastritis, gastroduodenal ulcers, and cancer. The factors that determine disease development in a small percentage of infected individuals are still not fully understood. LÄS MER

  7. 5. Host-Pathogen Responses during Giardia infections

    Författare :Emma Ringqvist; Staffan Svärd; Patricia Johnson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Giardia; parasite infection; host-parasite releationship; immune activation; virulence factor; immune evasion; Cell and molecular biology; Cell- och molekylärbiologi; Microbiology; Mikrobiologi; mikrobiologi; Microbiology;

    Sammanfattning : Giardia lamblia is a eukaryotic parasite of the upper small intestine of humans and animals. The infecting trophozoite cells do not invade the epithelium lining of the intestine, but attach to the brush border surface in the intestinal lumen. The giardiasis disease in humans is highly variable. LÄS MER
