6. Complement aberrations and autoantibodies to complement proteins in relation to disease mechanisms
Abstract : The complement system, a part of the innate immune system with several links to the adaptive immune system, plays an important role in the pathogenesis of many diseases. The purpose of this thesis was to document and clarify some of these mechanisms. The thesis is based on four papers (I-IV). READ MORE

7. The role of the complement system in arthritis and stroke
Abstract : Complement is part of the innate immune system and functions primarily as a first line of defense against invading microorganisms. It is a complex cascade, which can be activated via three pathways: the classical, alternative and mannan-binding lectin pathway. READ MORE

8. Rules of engagement - Regulation of complement response in tissue
Abstract : Always in motion and probing for danger, complement proteins are found in every space and notch of the body. Their omnipresence combined with an ability to wreak havoc when activated, mandates a strong leash! The how, when, and where to unleash or constrain the complement response remain partly answered questions, despite the significant progress made in the field in the past 100 years. READ MORE

9. Interactions between Streptococcus pyogenes and the human immune defence
Abstract : 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.

10. Interactions between extracellular matrix proteins and the complement system - In the perspective of cartilage degradation in inflammatory joint diseases
Abstract : Abstract: The joint diseases osteoarthritis and rheumatoid arthritis are characterized by destructive inflammatory processes that result in pathological changes of the joint tissues, including proteolytic degradation of cartilage and release of extracellular matrix proteins or fragments to the synovial fluid. The complement system, which is a part of the innate immune system, plays a central role in promoting the joint inflammation in these diseases. READ MORE
