1. 1. Antibody Evolution and Repertoire Development

   Författare :Johan Lantto; Institutionen för immunteknologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Immunology; serology; transplantation; Immunologi; serologi; virus neutralization; trinucleotide repeat; insertion; immunoglobulin variable genes; human cytomegalovirus; glycoprotein B; deletion; antibody; antibody repertoire;

   Sammanfattning : Antibodies are key players of the immune system in higher vertebrates, which provide a defense against potentially lethal threats from the environment. Besides their importance in the immune defense, antibodies have a great potential as reagents in biological chemistry and diagnostics, and as therapeutic agents against both infectious diseases and cancer.

3. 2. Cellular responses to amyloid-beta protofibrils : Focus on astrocytes, extracellular vesicles and antibody treatment

   Författare :Elisabeth Nikitidou; Anna Erlandsson; Martin Ingelsson; Gunnar K. Gouras; Uppsala universitet; []
   Nyckelord :Alzheimer’s disease; Amyloid-beta; Protofibrils; Astrocytes; Extracellular vesicles; Antibody; Neurons; Degradation; Medicinsk vetenskap; Medical Science;

   Sammanfattning : Knowledge about the cellular mechanisms behind the initiation and propagation of Alzheimer’s disease (AD) is limited. Decades of research have focused on neuronal abnormalities in AD, but recently more attention has been given to the glial cells. LÄS MER

4. 3. Antibody Development - Examples from viral and proteomic studies

   Författare :Fredrika Carlsson; Institutionen för immunteknologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; proteome specific antibodies; cytomegalovirus; phage display; antibody characterization; antibody development; antibody repertoires;

   Sammanfattning : This thesis, which is based on four original papers, covers different aspects of antibody development. The overall goal of my work has been to obtain an increased understanding of antibody repertoires as they develop in vivo and in vitro. LÄS MER

5. 4. IgM and Complement in Regulation of Antibody Responses

   Författare :Anna Sörman; Birgitta Heyman; Michael Holers; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; IgG; GC responses; feedback regulation; T-cell responses; antigen presentation; complement receptors 1 and 2; Immunologi; Immunology;

   Sammanfattning : Animals deficient in complement components C1q, C4, C3, and CR1/2 have severely impaired antibody responses. C1q is primarily activated by antibody-antigen complexes. Antigen-specific IgM in complex with an antigen is able to enhance the antibody response against that antigen. This is dependent on the ability of IgM to activate complement. LÄS MER

7. 5. 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
