  1. 1. Neutrophil recruitment in periodontal disease

    Författare :Agnes Dahlstrand Rudin; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neutrophil; periodontitis; P. gingivalis; F. nucleatum; SCFA; FFAR2; CD177; A1AT;

    Sammanfattning : Neutrophils are the first immune cells to arrive in infected or injured tissues, where they engulf microbes and clean up cell debris. Periodontitis is one of the typical symptoms of both neutropenia and defect neutrophil functionality, suggesting an important role for these cells in maintenance of periodontal health. LÄS MER

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

    Författare :Reza Ebrahimzadeh Pirshahid; Göteborgs universitet; []
    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

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

    Författare :William Agace; Slemhinnans immunologi; []
    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

  5. 4. Mechanisms of neutrophil recruitment in septic lung injury

    Författare :Karzan Palani; Kirurgi; []
    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.

  7. 5. Neutrophil Chemotaxis and Respiratory Burst in Term and Preterm Newborn Infants

    Författare :Maria Stålhammar; Richard Sindelar; Jens Schollin; Uppsala universitet; []
    Nyckelord :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.
