1. 21. 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.

3. 22. Feedback Enhancement of Antibody Responses via Complement and Fc Receptors

   Författare :Jörgen Dahlström; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Genetics; Mouse; transgenic knockout; immune regulation; B lymphocytes; Fc receptors; complement; IgG; IgM; IgE; Fc-gamma-RI; Fc-gamma-RII; Fc-gamma-RIII; CR1; CR2; CD21; CD35; Genetik; Clinical genetics; Klinisk genetik; Pathology; patologi;

   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.

4. 23. The role of the complement system in arthritis and stroke

   Författare :Max Albert Hietala; Göteborgs universitet; []
   Nyckelord :complement; C3; factor B; transgenic knockout; arthritis; focal cerebral ischemia;

   Sammanfattning : 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. LÄS MER

5. 24. Regulation of hematopoiesis by the Smad signaling pathway

   Författare :Ulrika Blank Savukinas; Avdelningen för molekylärmedicin och genterapi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicine human and vertebrates ; retroviral mediated gene expression; conditional knockout; hematopoietic stem cell; hematopoiesis; Transforming growth factor-beta; Smad signaling; Medicin människa och djur ;

   Sammanfattning : Hematopoietic stem cells (HSCs) reside in the bone marrow (BM) of adult individuals and are ultimately responsible for the continuous production of blood cells throughout life. The regulation of HSCs in vivo is tightly regulated by both intrinsic and extrinsic factors. LÄS MER

7. 25. Fcγ Receptors in the Immune Response

   Författare :Teresita Díaz de Ståhl; Jan van de Winkel; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Genetics; Fc Receptors; IgG Receptors; IgE Receptors; Immune regulation; In vivo animal models; Mouse; Rh prophylaxis; Rheumatoid arthritis; Transgenic knockout; Genetik; Clinical genetics; Klinisk genetik; Pathology; patologi;

   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
