  2. 1. Antibody Evolution and Repertoire Development

    Author : Johan Lantto; Institutionen för immunteknologi; []
    Keywords : 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;

    Abstract : 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.

  4. 2. Generation and evolution of human antibody repertoires

    Author : Helena Persson; Institutionen för immunteknologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; specificity; Immunology; serology; transplantation; Immunologi; serologi; Biotechnology; Bioteknik; phage display; IgE; hapten; grass pollen allergen; diversity; antibody repertoire; antibody library; antibody evolution; affinity maturation; allergy;

    Abstract : This thesis, which is based on five original papers, covers different aspects of antibody specificity and diversity, with the overall goal to understand the makeup of antibody repertoires and their functionality as they occur in vivo or as they are developed in the laboratory. Besides their importance in the adaptive immune response, antibodies have emerged as an invaluable tool in applications ranging from basic research to disease diagnostics and therapy. READ MORE

  5. 3. Studies on Potency and breadth of HIV-1, HIV-2 and SIV neutralizing antibody responses

    Author : Gülsen Özkaya Sahin; Avdelningen för medicinsk mikrobiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; HIV-1; HIV-2; SIV; envelope; neutralizing antibody; breadth; potency; IgG; IgA; complement; antibody-dependent complement-mediated inactivation; virus evolution; diversity; divergence;

    Abstract : Even though the relative contribution of neutralizing antibodies (Nab) to prevent progression to AIDS during HIV-1 infection is still unclear, the induction of broadly NAb directed against HIV-1 through vaccination is considered to represent an important goal for the development of HIV-1 vaccines. Factors contributing to the induction of NAb may include the strength and duration of antigenic stimulation, the preservation of CD4+ T and B cells, the conformation of the HIV-1 envelope glycoprotein complex (Env), and the evolution of Env during infection.

  6. 4. Intrapatient evolution of HIV-1 in the context of coreceptor usage

    Author : Mattias Mild; Avdelningen för medicinsk mikrobiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; coreceptor switch; Medicine human and vertebrates ; Medicin människa och djur ; biological cloning; R5-X4; coreceptor usage; glycosylation; recombination; HIV; evolution;

    Abstract : The variable region 1 to 3 (V1-V3) of the HIV-1 envelope plays an important role in coreceptor usage. Early in infection HIV- 1 is using CCR5 as coreceptor to enter target cells (R5 viruses) whereas viruses using CXCR4 as coreceptor (X4 viruses) may appear later in infection. READ MORE

  7. 5. Influenza A Virus : Spatial analysis of influenza genome trafficking and the evolution of the neuraminidase protein

    Author : Dan Dou; Robert Daniels; Martin Schwemmle; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Influenza A virus; IAV; neuraminidase; NA; IAV genome trafficking; viral entry; viral replication; co-infection; antigenic drift; antigenic shift; NA assembly; transmembrane domain; evolution; Biochemistry; biokemi;

    Abstract : Influenza A viruses (IAVs) are a common infectious agent that seasonally circulates within the human population that causes mild to severe acute respiratory infections. The severity of the infection is often related to how the virus has evolved with respect to the pre-existing immunity in the population. READ MORE
