1. 6. Glucose and insulin modulate phagocytosis and production of reactive oxygen metabolites in human neutrophil granulocytes

   Författare :Daniel Saiepour; Per-Arne Oldenborg; Janove Sehlin; Olle Stendahl; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neutrophil granulocytes; glucose; insulin; protein kinase C; diacylglycerol; phagocytosis; respiratory burst; diabetes; Histology; Histologi;

   Sammanfattning : Neutrophil granulocytes play an important role in the host defence against invading microorganisms and constitute the frontline of defence within the innate immune system and are among the first cells to arrive at the site of inflammation. Effective phagocytosis and killing of invading pathogens by neutrophils is of significant importance for successful resistance to infectious diseases. LÄS MER

3. 7. Neutrophil phagocytosis and secretion : The role of calcium and the cytoskeleton

   Författare :Lena Serrander; Joel D. Ernst; Linköpings universitet; []
   Nyckelord :MEDICINE; MEDICIN;

   Sammanfattning : Neutrophils assure rapid removal of bacteria by a variety of processes. They crawl out of the vessels, phagocytose the bacteria and kill them by secretion of bactericidal substances and production of oxidative metabolites. LÄS MER

4. 8. Storage organelles that are distinct from the classical granules in human neutrophils

   Författare :Sara Pellmé; Göteborgs universitet; []
   Nyckelord :neutrophil; HL-60 cells; cytoplasts; granules; CXCL-8; ER; phagocytosis; HLA-I; subcellular fractionation; immunogold;

   Sammanfattning : The human neutrophil is a crucial participant in acute inflammation. Appropriate immune response is dependent on rapid direction of phagocytic cells through the tissue, towards the inflammatory focus. Such movement is governed by chemoattractants, e.g. LÄS MER

5. 9. Exploring Monoclonal Antibody Action Against the Group A Streptococcal M Protein

   Författare :Sebastian Wrighton; Infektionsmedicin; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; group A streptococcus; Streptococcus pyogenes; fibronectin; phagocytosis; innate immunity; antibodies; adaptive immunity;

   Sammanfattning : Group A Streptococcus (GAS) is a significant human pathogen that has developed multipleimmune evasion mechanisms to counter the host immune response. One of these mechanisms involvesthe production of the M protein, which, amongst other things, acts as an anti-phagocytic factor and canbind host proteins. LÄS MER

7. 10. Leishmania donovani Lipophosphoglycan : Modulation of Macrophage and Dendritic Cell Function

   Författare :Katarina Tejle; Birgitta Rasmusson; Karl-Eric Magnusson; Olle Stendahl; Marita Troye-Blomberg; Linköpings universitet; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Lipophosphoglycan; Leishmania donovani; macrophage; actin; phagocytosis; PKC alpha; dendritic cell; Microbiology and immunology; Mikrobiologi och immunologi;

   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
