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

    Författare :Nele de Klerk; Ann-Beth Jonsson; Teresa Frisan; Stockholms universitet; []

    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. Adenovirus-host interactions : implications for tropism and therapy

    Författare :Annasara Lenman; Niklas Arnberg; Lennart Svensson; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Adenoviridae; Amino Acids; Antiviral Agents; Epithelial Cells; Factor IX;

    Sammanfattning : Human adenoviruses (HAdVs) are common viruses often associated withgastrointestinal, ocular and respiratory infections. They can infect a widevariety of cells, both dividing and non-dividing. HAdVs attach to and infecttarget cells through interactions with cellular receptors. LÄS MER

  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. 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.

  7. 5. Evolutionary genomics of host-microbe interactions

    Författare :Elin Videvall; MEMEG; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; host; microbiota; avian malaria; ostrich; parasite; dual RNA-seq;

    Sammanfattning : The microbes living inside hosts have highly important consequences for host health and fitness. From the host’s perspective, some microbes exhibit mutualistic tendencies, others parasitic, and some commensal, but this is context-dependent and opportunistic lifestyles are widespread in nature.
