  2. 21. Links between activation and cytoskeletal regulation of B lymphocytes

    Author : Gediminas Greicius; Edvard Smith; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Zoological Developmental Biology; zoologisk utvecklingsbiologi;

    Abstract : Interplay between adhesion molecules and the cytoskeleton is involved in many aspects of B lymphocyte behaviour during an immune response. Events such as cell polarisation and locomotion, collaboration with T lymphocytes and segregation in secondary lymphoid tissues all include mechanisms that recognise microenvironment and accordingly adjust morphological features of the cell.

  4. 22. Mediator synergism in mast celldependent inflammation : role of histamine for leukocyte recruitment

    Author : Henrik Thorlacius; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Chemoattractants; dexamethasone; histamine; inflammation; intravital microscopy; mast cells; leukocyte adhesion; leukocyte rolling; microcirculation; mast cells; nitric oxide; leukotrienes; P-selectin.;

    Abstract : The aim of the present thesis was to study functional interactions between histamine and chemotactic mediators, and the role of histamine for leukocyte recruitment in mast cell-dependent inflammation. Leukocyte rolling, adhesion and emigration. READ MORE

  5. 23. Platelet activation and tissue factor release in hemolytic uremic syndrome

    Author : Anne-lie Ståhl; Lund Pediatrik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hemolytic uremic syndrome; platelets; tissue factor; LPS; Shiga toxin; complement system; factor H; clusterin;

    Abstract : Hemolytic uremic syndrome (HUS) is a clinical syndrome characterized by microangiopathic hemolytic anemia, thrombocytopenia and acute renal failure. There are two subtypes: typical HUS associated with enterohemorrhagic E. coli (EHEC) and atypical HUS associated with uninhibited activation of the alternative pathway of complement. READ MORE

  6. 24. Leukocyte recruitment and control of vascular permeability in acute inflammation

    Author : Ellinor Kenne; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The inflammatory process is fundamental in host defense against tissue injury or infection. However, the inflammatory reaction may itself cause harm to the host and contribute to tissue damage and organ dysfunction. Leukocyte recruitment and edema formation are key components of the inflammatory response. READ MORE

  7. 25. Signaling determinants in Trojan horse-mediated dissemination of Toxoplasma gondii

    Author : Einar B. Ólafsson; Antonio Barragan; Eva Frickel; Stockholms universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Apicomplexa; leukocyte motility; dendritic cell; amoeboid migration; host-parasite interactions; podosome; integrin; ITGB1; ECM; MAT; TIMP; MMP; MAPK; Erk; RTK; HGFR; Ras; calcium; VDCC; VGCC; calmodulin; CaMkII; CD63; FAK; SRC; Pi3k; hypermigration; molekylär biovetenskap; Molecular Bioscience;

    Abstract : Toxoplasma gondii is an obligate intracellular parasite that infects all warm-blooded vertebrates including one third of the global human population. While infection is typically asymptomatic in healthy human hosts, reactivated and acute infection in immunosuppressed or immunecompromised individuals can lead to lethal toxoplasmic encephalitis After ingestion, the parasite crosses the intestinal epithelium and rapidly achieves systemic dissemination, ultimately establishing chronic infection in the brain.
