1. Fc receptors and feedback regulation by antibodies
Sammanfattning : The purpose of this investigation was to determine the role of Fc receptors for IgG (FcγRI, FcγRIIB, FcγRIII and FcRn) in immunoregulation. IgG is known to enhance the response to soluble antigens such as bovine serum albumin whereas the response to particulate antigens is suppressed. LÄS MER
2. Feedback Enhancement of Antibody Responses via Complement and Fc Receptors
Sammanfattning : IgG, IgM and IgE in complex with antigen have the capacity to regulate specific immune responses. In this investigation, the role of Fc receptors for IgG (FcγRI, FcγRII and FcγRIII) and complement receptors 1 and 2 (CR1/2) for antibody-mediated enhancement of antibody responses are investigated. LÄS MER
3. Fcγ Receptors in the Immune Response
Sammanfattning : Circulating immune complexes play an important role in the modulation of antibody responses and in the pathogenesis of immune diseases. This thesis deals with the in vivo regulatory properties of antibodies and their specific Fc receptors. LÄS MER
4. Fc receptors and feedback enhancement of antibody responses
Sammanfattning : Antibodies are important for the defence against microorganisms, but are also involved inpathological reactions such as allergy or autoimmunity. The exact mechanisms involved inregulation of antibody responses is still largely unknown. In this thesis, immune regulationby antibodies and the receptors they bind to (FcR), were investigated.

5. The Role of Fc Gamma Receptors in Experimental Arthritis
Sammanfattning : Induction of collagen-induced arthritis (CIA), an animal model for human rheumatoid arthritis, is dependent on anti-collagen type II (CII) antibodies. The effector mechanism by which autoantibodies contribute to inflammatory reactions in autoimmune diseases is not well understood. LÄS MER
