16. Staphylococcal enterotoxin H - structure and function of a superantigen
Sammanfattning : The aim of this thesis was to characterise the biological functions of the superantigen staphylococcal enterotoxin H (SEH). Superantigens are highly immunostimulatory proteins, which crosslink T cells and antigen presenting cells (APCs). LÄS MER
17. Interplay between superantigens and immunoreceptors
Sammanfattning : This thesis deals with the interactions between superantigens and their receptors. Superantigens are proteins that are secreted by various bacteria, such as Staphylococcus aureus and Streptococcus pyogenes. Superantigens are able to cross-link T cells and antigen presenting cells by binding to the T cell receptor (TCR) and MHC class II. LÄS MER
18. Dendritic cell presentation of type II collagen
Sammanfattning : Type II collagen (CII) is the main protein component of cartilage and immune recognition of CII plays a critical role for the development of collagen induced arthritis (CIA), a widely used animal model for rheumatoid arthritis (RA). Antigen presentation is an important requirement for the immune response, the more efficient presentation of the antigen the better tolerance will be induced and thereby protect against arthritis.

19. The Germinal Centre reaction - Genetic and proteomic analysis of factors important for survival and growth of B lymphocytes
Sammanfattning : During an immune response the B lymphocytes main function is to produce antibodies in the specific defence against the pathogen. When naïve B lymphocytes become activated by binding of an antigen, the cells differentiate to become antibody producing plasma cells. LÄS MER
20. The importance of major histocompatibility complex class II genes for the development of autoimmune inflammation
Sammanfattning : In this thesis the role of major histocompatibility complex (Mhc) class II molecules in development of autoimmune disease such as rheumatoid arthritis (RA), was studied. By combining an experimental model for RA, collagen type II induced arthritis (CIA), with molecular biology methods the importance of polymorphism in Mhc class II genes for disease development was investigated.
