1. 1. Antibody Feedback Regulation and T Cells

   Författare :Fredrik Carlsson; Birgitta Heyman; Alf Grandien; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Fc receptors; B cell; T cell; antigen presentation; complement receptors; complement; IgE; IgG3; CD23; antibody; Immunology; Immunologi;

   Sammanfattning : Antibodies, passively administered or actively produced, regulate immune responses to the antigen they recognize. This phenomenon is called antibody-mediated feedback regulation. Feedback regulation can be positive or negative, resulting in >1000-fold enhancement or >99% suppression of the specific antibody response. LÄS MER

3. 2. Fc receptors and feedback enhancement of antibody responses

   Författare :Sara Wernersson; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Genetics; mouse; transgenic knockout; immune regulation; B lymphocytes; Fc receptors; IgG; IgE; FcgRI; FcgRII; FcgRIII; CD23; Genetik; Clinical genetics; Klinisk genetik; Pathology; patologi;

   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.

4. 3. Fc receptors and feedback regulation by antibodies

   Författare :Mikael Karlsson; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Genetics; Mouse; B lymphocytes; Fc; receptors; IgG; IgE; FcgRI; FcgRII; FcgRIII; Fc e RI; CD23; Rh prophylaxis; Haemolytic disease of the newborn; Genetik; Clinical genetics; Klinisk genetik; Pathology; patologi;

   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

7. 5. Diffuse large B-cell lymphoma - tumour characteristics on RNA and protein level associated with prognosis

   Författare :Johan Linderoth; Bröstcancer-genetik; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cancerology; Cytologi; Cytology; oncology; prognosis; Diffuse large B-cell lymphoma; CD40; gene expression profiling; tumour microenvionment; Medicin människa och djur ; Medicine human and vertebrates ; onkologi; cancer;

   Sammanfattning : Diffuse large B-cell lymphoma (DLBCL) is the most frequent lymphoma subtype. In Sweden 450 new cases are diagnosed annually. With modern anthracycline-containing chemotherapy DLBCL is potentially curable, with an estimated overall cure rate of approximately 50% for patients with advanced stage disease. LÄS MER
