  1. 1. Studies on hereditary C2 deficiency: Frequent occurrence of severe infections, atherosclerosis and rheumatological manifestations

    University dissertation from Department of Medical Microbiology, Lund University

    Author : Göran Jönsson; Lund University.; Lunds universitet.; [2007]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; transplantation; serology; Immunology; mykologi; bakteriologi; virologi; Mikrobiologi; mycology; Complement; Complement C2 deficiency; Infectious diseases; Atherosclerosis; SLE; Autoantibodies; GM allotypes; Immunodeficiency state; Medicine human and vertebrates ; Medicin människa och djur ; Microbiology; virology; bacteriology; Immunologi; serologi; Infections; Infektioner;

    Abstract : The complement system is a part of the innate immunity and is essential in the defence against microorganisms. Hereditary C2 deficiency (C2D) is one of the most common complement deficiency states with an estimated prevalence of 1:20,000 in persons of Western descent. READ MORE

  2. 2. Streptococcus pyogenes and its interactions with the human host

    University dissertation from Ulrika Ringdahl, Bardisangränden 3 E, 226 48 Lund

    Author : Ulrika Ringdahl; Lund University.; Lunds universitet.; [2002]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Infections; mykologi; virologi; bakteriologi; M protein; Streptococcus pyogenes; plasminogen; fibrinogen; phagocytosis; platelet; Microbiology; bacteriology; virology; Mikrobiologi; mycology; Infektioner; Immunology; serology; transplantation; Immunologi; serologi;

    Abstract : 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. READ MORE

  3. 3. Pathogen-host interactions at the surface of Streptococcus pyogenes

    University dissertation from KFS AB

    Author : Patrik Nyberg; Lund University.; Lunds universitet.; [2005]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Infektioner; Infections; C3a; LL-37; antimicrobial peptide; GRAB; alpha-2-macroglobulin; proteolysis; SpeB; internalization; virulence; protein F1; Streptococcus pyogenes; fibronectin;

    Abstract : The bacterial surface can be thought of as the interface where pathogenic bacteria encounter the human host. Interactions between bacterial surface proteins and human proteins are important determinants of the eventual outcome of infection. READ MORE

  4. 4. Interactions between streptococcal M proteins and human plasma proteins

    University dissertation from Department of Laboratory Medicine, Lund University

    Author : Charlotta Sandin; Lund University.; Lunds universitet.; [2005]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Infektioner; Infections; innate immunity; Streptococcus pyogenes; phagocytosis resistance;

    Abstract : Streptococcus pyogenes is a common human pathogen, which causes a variety of diseases. A major virulence factor of S. pyogenes is the surface-associated M protein, which mediates resistance to phagocytosis. Several studies indicate that M proteins inhibit complement deposition and thereby phagocytosis. READ MORE

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

    University dissertation from Department of Infectious Diseases, Lund University

    Author : Hans Norrgren; Lund University.; Lunds universitet.; [1998]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Infections; Africa; Guinea-Bissau; AIDS; HIV-1; HIV-2; Infektioner;

    Abstract : 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. READ MORE
