    Sammanfattning : Although macroalgae usually are inconspicuous on pristine coral reefs, they often thrive on reefs that are subjected to various types of anthropogenic disturbance. This thesis consists of five papers and investigates how biomass and composition of macroalgal communities on coral reefs are affected by regulating factors, such as nutrient availability, herbivory, substrate availability and hydrodynamic forces.

  2. 2. Transcription factors regulating the Btk promoter

    Författare :Susanne Müller; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; Btk; X-linked agammaglobulinemia; transcription factors; repression; synergism; Sp 1; Sp3; PU.l; Spi-B; genetherapy.;

    Sammanfattning : Bruton's agammaglobulinemia tyrosine kinase (Btk) is a cytoplasmic tyrosine kinaserelated to the Src family of kinases. Mutations in various parts of the gene havebeen shown to lead to X-linked agammaglobulinemia, an immunodeficiency disease whichis characterized by a defect in B-cell development. LÄS MER

    Sammanfattning : The mature vascular system is composed of a network of blood vessels organized into arteries, capillaries, and veins. The vessels are composed of endothelial cells surrounded by smooth muscle cells and embedded in a specialized basement membrane. LÄS MER

  4. 4. Factors regulating lymphocyte development and peripheral activation

    Författare :Anna Makowska; Malmö Institutionen för kliniska vetenskaper; []

    Sammanfattning : Peripheral tolerance is regulated by different types of regulatory T cells, including CD1-restricted T cells and CD4+CD25+ regulatory T (Treg) cells. This thesis has focused on the interactions between T cells and antigen presenting cells (APCs) and the immunregulatory function of TGF-b as two important factors regulating differentiation and activation of T cells in the periphery.
