  1. 11. Structural and functional studies on nerve regeneration in the rat

    Författare :Bo Povlsen; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Peripheral nerves cannot be repaired, but they may be helped to regenerate. The results of surgical treatment of nerve injuries remain disappointing, however. This is a biological rather than a technical challenge. LÄS MER

  3. 12. Apoptosis of Peripheral Blood Leukocytes in Systemic Lupus Erythematosus: Studies on Serum Induction and Complement-Dependent Clearance Mechanisms

    Författare :Birgitta Gullstrand; immunologi och glykobiologi - MIG Avdelningen för mikrobiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Complement; Apoptosis; SLE; Autoimmunity;

    Sammanfattning : Systemic lupus erythematosus (SLE) is an autoimmune disease involving many organ systems. The cause is not known, but a complex combination of environmental and genetic factors seems to be involved. LÄS MER

  4. 13. Interactions between Streptococcus pyogenes and the human immune defence

    Författare :Maria E Nilsson; immunologi och glykobiologi - MIG Avdelningen för mikrobiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; M protein; Streptococcus pyogenes; Streptolysin O; The complement system; Neutrophils; Biomedical sciences; Biomedicinska vetenskaper; General biomedical sciences; Biomedicinska vetenskaper allmänt ; Microbiology; transplantation; Immunology; serology; mykologi; virologi; bakteriologi; Mikrobiologi; mycology; virology; Immunologi; serologi; Infections; Infektioner; Clinical biology; Klinisk biologi; bacteriology;

    Sammanfattning : Streptococcus pyogenes is an important human pathogen frequently colonizing the throat and skin of humans. To facilitate colonization and spread and to avoid the host immune defence, streptococci are endowed with a variety of virulence factors, two of which are investigated in this thesis namely streptolysin O (SLO) and M protein.

  5. 14. Role of the Yersinia protein YopK in microbe-host interactions

    Författare :Sara Thorslund; Maria Fällman; James Bliska; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Yersinia; YopK; T3SS; antiphagocytosis; neutrophil; translocation; virulence; molekylärbiologi; Molecular Biology;

    Sammanfattning : There are three human pathogenic species of the genus Yersiniae: Yersinia pestis, Yersinia enterocolitica, and Yersinia pseudotuberculosis. To cause disease, these strains inhibit several key innate defense mechanisms, including phagocytosis, the critical process for bacterial clearance. LÄS MER

  7. 15. Inflammatory cell death of human macrophages induced by Aggregatibacter actinomycetemcomitans leukotoxin

    Författare :Peyman Kelk; Anders Johansson; Charels A Dinarello; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Aggregatibacter actinomycetemcomitans; leukotoxin; IL-1β; caspase-1; inflammatory cell death; pyroptosis; ODONTOLOGY; ODONTOLOGI; odontologi; Odontology;

    Sammanfattning : Aggregatibacter (Actinobacillus) actinomycetemcomitans is a bacterium mainly associated with aggressive forms of periodontitis. Among its virulence factors, a leukotoxin is suggested to play an important role in the pathogenicity. LÄS MER
