  1. 1. Leukocyte responses to pathogens : integrins, membrane rafts and nitric oxide

    Author : Martin Winberg Tinnerfelt; Birgitta Rasmusson; Maria Lerm; Eva Särndahl; Hans Tapper; Håkan Eriksson; Linköpings universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICINE; MEDICIN;

    Abstract : During microbial invasion, leukocytes of the innate immunity are rapidly recruited to the site of infection where they internalize (phagocytose), kill and digest the invaders. To aid this process, leukocytes express surface receptors such as Toll-like receptors, β2-integrins and Fc-receptors. READ MORE

  2. 2. Mucosal immunity in the respiratory tract : The role of IgA in protection against intracellular pathogens

    Author : Ariane Rodríguez; Carmen Fernández; Lennart Hammarström; Stockholms universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mucosal immunity; respiratory tract; IgA; intracellular pathogens; Immunology; Immunologi;

    Abstract : The lungs and upper airways are mucosal surfaces that are common site for infection with an enormous variety of inhaled pathogens. Therefore, induction of immune responses in the respiratory tract is crucial for protection against respiratory diseases. One of the pathogens infecting the host via the respiratory tract is Mycobacterium Tuberculosis. READ MORE

  3. 3. Pathogen entry mechanisms and endocytic responses to plasma membrane damage

    Author : Lars Nygård Skalman; Richard Lundmark; Kristian Riesbeck; Umeå universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; NATURAL SCIENCES; MEDICAL AND HEALTH SCIENCES; Endocytosis; plasma membrane; pathogens; virus; bacterial membrane vesicles; Helicobacter pylori; adenovirus 37; listeriolysin O; pore-forming toxins; membrane repair;

    Abstract : Endocytosis is a fundamental cellular process by which cells transport material from the outside to the inside of the cell through the formation of membrane invaginations that bud off from the plasma membrane. This process is important for nutrient uptake, regulating cell surface receptors and the overall plasma membrane composition. READ MORE

  4. 4. Microbial risk assessment and its implications for risk management in urban water systems

    Author : Therese Westrell; Thor-Axel Stenström; Nick Ashbolt; Linköpings universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Quantitative microbial risk assessment; pathogens; urban; decentralised; failures; noroviruses; water consumption; HACCP; drinking water; wastewater; sludge; faeces; risk management; Water in nature and society; Vatten i natur och samhälle;

    Abstract : Infectious disease can be transmitted via various environmental pathways, many of which are incorporated into our water and wastewater systems. Quantitative microbial risk assessment (QMRA) can be a valuable tool in identifying hazard exposure pathways and estimating their associated health impacts. READ MORE

  5. 5. Spatial patterns in the interaction between Salix triandra and associated parasites

    Author : Lena Niemi; Anders Wennström; Lars Ericson; Keith Clay; Umeå universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Gonioctena linnaeana; host-parasite interactions; leaf beetle; local adaptation; Melampsora amygdalinae; phenolics; pathogens; plant host; secondary chemistry; Terrestrial ecology; Terrestisk ekologi;

    Abstract : This thesis focuses on mechanisms and processes underlying spatial patterns of resistance and virulence and on local adaptations in plant–parasite interactions. The model system used comprises the plant host Salix triandra, the pathogenic rust fungus Melampsora amygdalinae, the leaf beetle Gonioctena linnaeana, and the galler Pontania triandrae. READ MORE
