  1. 1. Human Abuses of Coral Reefs- Adaptive Responses and Regime Transitions

    University dissertation from Stockholm : Institutionen för systemekologi

    Author : Ingrid Nordemar; Stockholms universitet.; [2004]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Coral Reefs; Disturbance; Stress; Adaptive responses; Macroalgae; Ecosystem regimes; Resilience; Competition; Traits; NATURAL SCIENCES Biology Terrestrial; freshwater and marine ecology; NATURVETENSKAP Biologi Terrestisk; limnisk och marin ekologi;

    Abstract : During the last few decades, coral reefs have become a disappearing feature of tropical marine environments, and those reefs that do remain are severely threatened. It is understood that humans have greately altered the environment under which these ecosystems previously have thrived and evoloved. READ MORE

  2. 2. Intestinal dendritic cell migration and induction of T cell responses

    University dissertation from Section for Immunology, Lund University

    Author : Karin Hägerbrand; Lund University.; Lunds universitet.; [2015]

    Abstract : The intestine represents the body’s largest surface exposed to the outer world and is thus a major entry site for pathogens such as bacteria and viruses. The intestinal immune system has the important task of protecting us against infection while maintaining tolerance against the vast amount of commensal microbes populating the intestinal tract and the multitude of foreign antigen present in the diet.

  3. 3. Regulatory properties of dendritic cells and B cells in adaptive immunity

    University dissertation from Bengt Johansson-Lindbom, Dept. of Immunotechnology, Sölvegatan 33A, 223 62 Lund

    Author : Bengt Johansson Lindbom; Lund University.; Lunds universitet.; [2002]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; serology; transplantation; Immunologi; serologi; Immunology; Cellular differentiation; Cytokines; Dendritic cells; B lymphocytes; T lymphocytes;

    Abstract : This thesis is based upon four original papers in which human dendritic cells (DCs) and B cells have been analyzed in terms of how they influence the character of adaptive immune responses. DCs isolated from human tonsils were found to possess a capacity to directly regulate proliferation, isotype switching, and antibody production in B cells. READ MORE

  4. 4. Adaptive responses during giardia-host interactions

    University dissertation from Stockholm : Karolinska Institutet, Microbiology and Tumor Biology Center (MTC)

    Author : Daniel Palm; Karolinska Institutet.; Karolinska Institutet.; [2005]

    Abstract : Giardia lamblia is a major cause of water-borne enteric disease. The parasite is a noninvasive, flagellated protozoan that inhabits the upper part of the small intestine of its vertebrate hosts. READ MORE

  5. 5. Regulation of the germinal center response by T follicular helper cells and type I interferons

    University dissertation from Faculty of Medicine, Lund University

    Author : Madelene Dahlgren; Lund University.; Lunds universitet.; [2016]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Germinal Center; T follicular helper cell; type I interferon; dendritic cell; adjuvant; differentiation; IgG;

    Abstract : The protective effect of most currently available vaccines is dependent on high-affinity antibodies and long lived B cell memory, which develop within organized structures of secondary lymphoid organs called germinal centers (GCs). GC formation is supported by T follicular helper (Tfh) cells, a subset of CD4+ T cells that develop in parallel to other effector T cells and specifically localizes to B cell follicles. READ MORE
