    Sammanfattning : Neutrophil granulocytes constitute the front line of defense in the innate immune response to invading microorganisms, but can also contribute to development of inflammatory disease and tissue destruction following e.g. myocardial infarction or stroke. LÄS MER

  3. 17. Perturbation of the epithelial barrier by enteric pathogens

    Författare :Farideh Tafazoli; Magnusson Karl-Eric; Hakon Leffler; Linköpings universitet; []
    Nyckelord :enteric pathogens: signal transduction; barrier function; MEDICINE; MEDICIN;

    Sammanfattning : Gastrointestinal infections in humans have been associated with a number of diseased condition, including stomach ulcers, gastroenteritis, Crohn's disease, and rheumatic arthritis. Such infections often cause altered intestinal permeability through perturbation of the tight junctions that hold epithelial cells together. LÄS MER

  4. 18. Leishmania donovani Lipophosphoglycan : Modulation of Macrophage and Dendritic Cell Function

    Sammanfattning : Leishmania donovani is a blood-borne tropicial parasite, which infects humans through bites by Phlebotomus sandflies. The parasite survives and multiplies inside macrophages in inner organs, and causes the deadly disease visceral leishmaniasis (Kala-Azar). LÄS MER

  5. 19. Complement activation - good or evil in HIV-1 infection? : interaction of free and complement opsonized HIV-1 with monocyte derived dendritic cells and immune cells in the cervical mucosa

    Författare :Veronica Tjomsland; Marie Larsson; Jorma Hinkula; Karl-Eric Magnusson; Barbara Shacklett; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : Worldwide, the heterosexual route is the most common mode of sexual transmission of HIV-1 and women are particularly susceptible to this infection. After penetration of the mucosal epithelium HIV-1 interacts with potential target cells, i.e. dendritic cells (DCs) and CD4+ T cells. LÄS MER

  7. 20. Sperm Membrane Channels, Receptors and Kinematics : Using boar spermatozoa for drug toxicity screening

    Författare :Alejandro Vicente Carrillo; Heriberto Rodríguez-Martínez; Karl-Eric Magnusson; Rudolf Rigler; Vesa Loitto; Stefan Arver; Linköpings universitet; []

    Sammanfattning : Internal fertilization usually implies that a spermatozoon, with intact attributes for zygote formation, passes all hurdles during its transport through the female genitalia and reaches the oocyte. During this journey, millions to billions of other spermatozoa perish. LÄS MER
