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. Regulation of neutrophil apoptosis

   Författare :Maria Alvarado-Kristensson; Malmö Molekylär patologi; []

   Sammanfattning : The human neutrophil is the most abundant granulocyte and the major type of cell involved in an acute inflammatory response. Neutrophils are armed with various systems of enzymes, that can find and kill pathogens, but unfortunately, these "weapons" cannot distinguish between the host tissues and the "invaders. LÄS MER

5. 4. The primed neutrophil : a friend or a foe in inflammation

   Författare :Per Follin; Staffan Ahlstedt; Linköpings universitet; []
   Nyckelord :MEDICINE; MEDICIN;

   Sammanfattning : Human neutrophils are the most abundant of the white blood cells in circulation and represent the first line of defense against invading microorganisms. With a membrane-bound enzyme system (the NADPH oxidase), these cells can generate reactive oxygen metabolites that serve efficiently in antimicrobial defense. LÄS MER

7. 5. Chemotactic factors in the human follicle at ovulation

   Författare :Eva Runesson; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; chemokine; follicle; gonadotropin; human; ovary; ovulation;

   Sammanfattning : Ovulation is initiated by the midcycle gonadotropin surge, which leads to a controlled degradation of the follicle wall ending in follicular rupture and oocyte extrusion. The gonadotropins triggers several biochemical and biophysical changes such as vascular alterations, increased proteolytic enzyme activity and leukocyte extravasation, within the preovulatory follicle.
