    Abstract : Background Dengue is a significant problem of international health concern. According to the World Health Organization in 2012, globally, dengue is “the most important mosquito borne viral disease” with incidence 30 higher than it had been 50 years ago. READ MORE

    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

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

    Author : Ulrika Ringdahl; Institutionen för Immunteknologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 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

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

    Author : Patrik Nyberg; Infektionsmedicin; []
    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

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

    Author : Charlotta Sandin; Avdelningen för medicinsk mikrobiologi; []
    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
