  2. 6. Studies on cell wall recycling and modification in Gram-negative bacteria

    Author : Michael C. Gilmore; Felipe Cava; Peter A Lind; Teresa Frisan; Jean-François Collet; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Peptidoglycan recycling; bacterial cell wall; antibiotics; Agrobacterium tumefaciens; Escherichia coli; Legionella pneumophila; mikrobiologi; Microbiology; Biochemistry; biokemi;

    Abstract : The bacterial cell wall is made from peptidoglycan (PG), a heteropolymer which forms a bag-like exoskeleton that envelopes the cell. PG is constantly remodelled during growth and division, and in response to environmental stimuli. READ MORE

  4. 7. Regulatory roles of two small RNAs in the human pathogen Listeria monocytogenes and the evaluation of an alternative infection model

    Author : Jonas Gripenland; Jörgen Johansson; Tom Geissmann; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; small RNA; sRNA; Riboswitch; Listeria monocytogenes; ncRNA; PrfA; molekylärbiologi; Molecular Biology;

    Abstract : Listeriosis is a potentially lethal disease caused by the Gram-positive facultative intracellular pathogen Listeria monocytogenes (L.m.). L. READ MORE

  5. 8. Probing and elucidating the dynamics of virus-membrane interaction via plasma membrane mimics

    Author : Konrad Thorsteinsson; Marta Bally; Hudson Pace; Gisa Gerold; Susan Daniel; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Plasma membrane; supported lipid bilayer; binding kinetics; equilibrium fluctuation analysis; TIRF; FRET; norovirus; HSV; SARS-CoV-2; histo-blood group antigens; ApoE; heparan sulfate; mikrobiologi; Microbiology;

    Abstract : Virus infection is initiated by the attachment of a virion to a susceptible cell’s plasma membrane, in a highly dynamic and well-orchestrated process that encompasses various steps and engages numerous viral and cellular factors. These dynamic steps may include initial non-specific binding to ubiquitous cell-membrane ligands, diffusion across the membrane to a suitable entry site and virus engagement with various receptors and co-receptors on the cell surface.

  6. 9. Evolution and host-specific adaptations of Legionella pneumophila

    Author : Anaísa B. Moreno; Lionel Guy; Dan I. Andersson; Fredrik Söderbom; Alexander W. Ensminger; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Evolution; Legionella pneumophila; host-adaptation; experimental evolution; Acanthamoeba castellanii; transfection; Mikrobiologi; Microbiology;

    Abstract : How bacteria evolve pathogenic traits is shaped by their communities and environments. Legionella pneumophila is ubiquitous in aquatic habitats, where it persists by replicating within a broad range of protozoan hosts. Using the same mechanisms, L. READ MORE

  7. 10. Genetic and serologic characterization of a Swedish human hantavirus isolate

    Author : Marie Lindkvist; Göran Bucht; Clas Alhm; Per Juto; Rainer Ulrich; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; hantavirus; puumalavirus; diagnostics; HFRS; nucleocapsid protein; B-cell epitopes; epitope-mapping; protein interactions; glycosylation; antibody response; cross-reactivity; Virology; Virologi;

    Abstract : Hantaviruses are found practically all over the world and cause hemorrhagic fevers in man. Each year about 150,000 people are hospitalized in these zoonotic infections which can be of two types: hemorrhagic fever with renal syndrome (HFRS) or hantavirus cardiopulmonary syndrome (HCPS), depending on the infecting virus.
