  2. 11. Matrix metalloproteinases in natural killer cells. Expression of MMPs, IL-2 activation and killer cell interactions with Matrigel® and model tumours

    Author : Per Albertsson; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Protease; matrix metalloproteinase; killer cell; IL-2; Matrigel; B16 melanoma; tumour infiltration; invasion assay; zymography; Western blot; RT-PCR; light microscopy; fluorescence; electron microscopy;

    Abstract : Introduction: IL-2 activated natural killer (A-NK) cells can recognize malignant cells and exert tumouricidal activities by multiple mechanisms that require close contact with the target cells. Upon adoptive transfer, some A-NK cells accumulate in tumours by migrating from the vascular bed to a position inside the malignant tissue, forming close contacts with target cells. READ MORE

  5. 13. Endosymbiosis of Frankia cluster-2

    Author : Fede Berckx; Katharina Pawlowski; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; root nodule endosymbiosis; Frankia; Datisca glomerata; nitrogen fixation; actinorhizal; peptidoglycan; RT-qPCR;

    Abstract : Actinobacteria of the genus Frankia engage in root endosymbiosis with actinorhizal plants belonging to the Fagales, Cucurbitales and Rosales. The genus Frankia consists of four different clades. Strains belonging to cluster-1, -2, and -3 exhibit host-specificity which plants they can nodulate, while cluster-4 strains do not engage in symbiosis. READ MORE

    Abstract : The gastrointestinal tract (GIT) regulates nutrient uptake, secretes hormones and has a crucial gut flora and enteric nervous system. Of relevance for these functions are the G protein-coupled receptors (GPCRs) and the solute carriers (SLCs). READ MORE

    Abstract : Aquatic organisms are constantly at risk of being exposed to potentially harmful chemical compounds of natural or anthropogenic origin. Biological life can for instance respond to chemical stressors by changes in gene expression, and thus, certain gene transcripts can potentially function as biomarkers, i.e. READ MORE
