  1. 36. Membrane traffic in neutrophils and neutrophil-like cells

    Författare :Susanne Bauer; Infektionsmedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Infections; membrane traffic; Hematologi; extracellular fluids; Haematology; Medicin människa och djur ; Medicine human and vertebrates ; CD177; extracellulära vätskor; PR3; phagocytosis; Streptococcus pyogenes; Infektioner; neutrophils;

    Sammanfattning : The neutrophil constitutes the first line of defence against invading organisms and its primary function is to recognize, phagocytose and kill intruding microorganisms. In this thesis, the membrane traffic in neutrophils and neutrophil-like cells was studied. Non-opsonised S. LÄS MER

  3. 37. Streptococcus pyogenes and its interactions with the human host

    Sammanfattning : We have found that a set of group A streptococcal strains, primarily associated with skin infections, express surface-associated M proteins that bind plasminogen and plasmin with high affinity. The binding is mediated by a common 13 amino acid internal repeated sequence located in the NH2-terminal surface-exposed portion of these M proteins. LÄS MER

  4. 38. Low CXCR1 Expression and Susceptibility to Acute Pyelonephritis

    Författare :Ann-Charlotte Lundstedt; immunologi och glykobiologi - MIG Avdelningen för mikrobiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; serology; transplantation; Immunology; mykologi; virology; mycology; Mikrobiologi; bakteriologi; virologi; Microbiology; bacteriology; Polymorphisms; Acute pyelonephritis; Chemokine receptor; serologi; Infections; Infektioner; Pediatrics; Pediatri; Immunologi;

    Sammanfattning : Urinary tract infections (UTIs) are clustered in certain individuals but the molecular basis of disease susceptibility is not known. A single gene was shown to control the susceptibility to acute pyelonephritis and renal scarring in mice. LÄS MER

  5. 39. HIV-2 infection in Guinea-Bissau, West Africa, with special reference to clinical, immunological and epidemiological aspects

    Författare :Hans Norrgren; Sektion III; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Infections; Africa; Guinea-Bissau; AIDS; HIV-1; HIV-2; Infektioner;

    Sammanfattning : We have followed a cohort of police officers in Guinea-Bissau between 1990 and 1997 for the study of clinical, immunological and epidemiological aspects of HIV-2 infection. Initially the prevalence of HIV-2 was high (11.6 %) and HIV-1 infection was rare (0. LÄS MER

  7. 40. 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.
