1. Interactions between Streptococcus pyogenes and the Human Immune System
Sammanfattning : Streptococcus pyogenes is a common human pathogen causing mild infections such as tonsillitis and pharyngitis, but is also the cause of life-threatening conditions. To be able to infect the human host, S. pyogenes express different virulence factors. The surface-expressed M protein is a major virulence factor of S. LÄS MER
2. Studies on streptococcal M proteins. Interactions with IgA and human complement regulators
Sammanfattning : The human pathogenic bacterium Streptococcus pyogenes (group A Streptococcus) expresses several different virulence factors. Of these, the M protein is regarded as one of the most important, because it confers resistance to phagocytosis, allowing the bacterium to multiply in blood. LÄS MER
3. Effects of galectins and antibodies in HIV infection; Novel Assays
Sammanfattning : The high variability of the HIV envelope glycoproteins (Env), and their heavy glycan coating, contributes to the limited host immune control. Still, broadly neutralizing antibodies (bnAbs) are found in some chronically infected HIV-infected individuals, which has spurred the research on antibody-based vaccines. LÄS MER
4. Streptococcal protein Rib and related proteins: a family of repetitive surface proteins that elicit protective immunity
Sammanfattning : ABSTRACT Streptococci constitute a heterogeneous group of Gram-positive bacteria, divided into different serological groups on the basis of antigenic differences in a cell wall-associated carbohydrate. This thesis describes related surface proteins expressed by bacteria in two of these groups, the group B streptococcus (GBS) and the group A streptococcus (GAS). LÄS MER
