  1. 1. Neutrophil chemotaxis. Analyses of neutrophil chemotaxis i a new fluid gradient chamber

    Detta är en avhandling från Göteborg

    Författare :Reza Ebrahimzadeh Pirshahid; Göteborgs universitet.; Gothenburg University.; [2000]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell movement; Chemotaxis; Leukocyte; Neutrophil; Human; Filter; Methods; N-Formylmethionine-Leucyl-Phenylalanine; Normal distribution; Partial differential equation;

    Sammanfattning : The leukocytes have, as part of their function in immune system, the ability to leave the bloodstream, penetrate the vascular wall and migrate towards extravascular targets. This behaviour of the leukocytes has been extensively studied both in vivo and in vitro since the 19th century but the mechanisms underlying leukocyte migration are not yet fully understood. LÄS MER

  2. 2. The role of the epithelial cell in Escherichia coli induced neutrophil migration into the urinary tract

    Detta är en avhandling från Divison of Medical Microbiology

    Författare :William Agace; [1996]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Immunology; E.coli; cytokines; epithelial cell; mucosal inflammation; neutrophil; serology; transplantation; Immunologi; serologi;

    Sammanfattning : This study examined the molecular mechanisms of neutrophil migration to sites of mucosal bacterial infection. (1) Bacterial induction of neutrophil chemotactic cytokines and their role in neutrophil migration. Uropathogenic E. LÄS MER

  3. 3. Mechanisms of neutrophil recruitment in septic lung injury

    Detta är en avhandling från Surgery Research Unit

    Författare :Karzan Palani; [2013]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; sepsis; infection; neutrophil; lung; chemokines; apoptosis; CD44; F-actin; peptides;

    Sammanfattning : Sepsis is one of leading cause of death despite aggressive surgical intervention and antibiotic therapies. Excessive neutrophil recruitment is a major feature in early phase with immune system dysfunction at later phase. Lung is the most vulnerable, critical and sensitive organ during sepsis process.

  4. 4. Neutrophil Chemotaxis and Respiratory Burst in Term and Preterm Newborn Infants

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Maria Stålhammar; Uppsala universitet.; [2016]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; innate immunity; neutrophil; term newborn infants; preterm newborn infants; chemotaxis; respiratory burst; reactive oxygen species; cell surface receptor; IL-8; bacterial N-formyl peptide;

    Sammanfattning : Neutrophil activation is the most important initial immune defense against invading microbes in newborn infants. The reduced neutrophil migration and uncontrolled regulation of reactive oxygen species (ROS) production observed in neonates, could result in a diminished infectious response or in tissue damage.

  5. 5. Neutrophil recruitment in H. pylori induced inflammation: characterization of regulatory factors

    Detta är en avhandling från Göteborg

    Författare :Mikael Innocenti; Göteborgs universitet.; Gothenburg University.; [2001]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Helicobacter pylori; endothelial cells; neutrophils; monocytes; transendothelial; migration; chemokines; cytokines; adhesion molecules inflammation; LPS; CagPAI; VacA;

    Sammanfattning : Helicobacter pylori, a bacterium colonizing the human gastric mucosa, is strongly associatedwith the development of gastric and duodenal ulcers, as well as gastric, adenocarcinoma.Virtually all infected individuals develop active chronic gastritis characterized by a continousinfiltration of neutrophils as well as mononuclear cells.
