21. Regulation of cell morphology and adhesion in B lymphocytes by interleukin-4
Sammanfattning : The different stages in lymphocyte differentiation and activation are associated with profound changes in cell morphology. Under normal development, lymphocytes are at different times in direct contact with stromal cells and extracellular matrix, they transverse endothelium, are transported via blood and lymphatic vessels, home to specific lymphoid organs and may undergo antigen-driven activation events.

22. Function and Regulation of B-cell Subsets in Experimental Autoimmune Arthritis
Sammanfattning : B lymphocytes play a significant role in autoimmune arthritis, with their function stretching beyond autoantibody production to cytokine secretion and presentation of autoantigen. However, the involvement and activation of different B-cell subset in the autoimmune response is not fully clear. LÄS MER
23. 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.

24. Role of Toll-like receptors in airway inflammation
Sammanfattning : Toll-like receptors (TLRs) are germline-encoded pathogen-recognition receptors that detect different microbial structures and activate the immune system. The human TLR family presently comprises ten members (TLR1-TLR10), each with distinct properties. LÄS MER
25. 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
