1. The Role of IgM and Complement in Antibody Responses
Sammanfattning : An intact complement system including the complement receptors 1 and 2 (CR1/2) is crucial for the generation of a normal antibody response in animals and humans. Moreover, activation of the classical pathway is thought to be important since deficiency in complement components C1q, C2, C4 or C3 lead to impaired antibody responses. LÄS MER
2. Feedback Enhancement of Immune Responses by IgE, IgM, and IgG3 Antibodies
Sammanfattning : Antibodies can enhance or suppress the immune responses against their specific antigens. This phenomenon is known as antibody-mediated feedback regulation. We have studied the mechanisms underlying IgE-, IgM-, and IgG3-mediated enhancement of immune responses in mouse models using intravenous immunization. LÄS MER
3. IgG3 Complements IgM in the Complement-Mediated Regulation of Immune Responses
Sammanfattning : An intact complement system is essential for the initiation of a normal antibody response. Antibodies can regulate their own production against the antigens that they are specific for. Both IgG3 and IgM are able to enhance the antibody response via complement. LÄS MER
4. Diagnostic and prognostic value of proteinuria in chronic renal diseases
Sammanfattning : To the extent that increased urinary protein excretion is an indicator of alterations of the glomerular capillary wall (GCW) and appearance of tubulointerstitial damage, proteinuria can be a good marker of the overall severity of the glomerular and tubulointerstitial damage, and therefore, the prognosis of glomerular diseases. Studies I, II, and III show that it is the type of proteinuria, rather than the degree of albuminuria, that predicts the progression in renal, proteinuric diseases. LÄS MER
5. 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.
