  2. 16. Glioma as an Ecosystem : Studies of Invasion, Onco-miR Addiction and Mast Cell Infiltration

    Author : Jelena Põlajeva; Bengt Westermark; Ingemar Ernberg; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; glioblastoma; mast cell; miR-21; RAP1; CXCL12; SOX2;

    Abstract : Despite recent advances in oncology and extensive research efforts, gliomas remain essentially incurable. Glioblastoma multiforme (GBM, WHO grade IV) is the most common glioma and may arise de novo or progress from a lower-grade lesion. GBM is characterized by invasive growth, aberrant angiogenesis and necrosis. READ MORE

  4. 17. The rhomboid family of intramembrane proteases, conserved regulators of cell communication

    Author : Marco Gallio; Per Kylsten; Pernille Rørth; Södertörns högskola; Karolinska Institutet; Karolinska Institutet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cell communication; proteolysis; EGF receptor; development; genetics;

    Abstract : The development of multicellular organisms relies heavily on cell communication. Cells send and receive complex sets of signals, harmonising their growth and differentiation with that of other, often distant, cell populations. In animals, the Epidermal Growth Factor Receptor (EGFR) is an important mediator of cell communication. READ MORE

  5. 18. Storage organelles that are distinct from the classical granules in human neutrophils

    Author : Sara Pellmé; Göteborgs universitet; []
    Keywords : neutrophil; HL-60 cells; cytoplasts; granules; CXCL-8; ER; phagocytosis; HLA-I; subcellular fractionation; immunogold;

    Abstract : The human neutrophil is a crucial participant in acute inflammation. Appropriate immune response is dependent on rapid direction of phagocytic cells through the tissue, towards the inflammatory focus. Such movement is governed by chemoattractants, e.g. READ MORE

  6. 19. Brain-derived neurotrophic factor and endocannabinoid functions in gabaergic interneuron development

    Author : Paul Berghuis; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Formation of the cerebral cortex is controlled by tightly regulated processes: the proliferation and survival decisions of neural progenitors, radial and tangential migration of neuronal precursors, axon guidance and dendritic growth underpinning the formation of synapses. Patterning of the neocortex has been extensively studied and significant progress has been made in understanding the principles of cortical neuronal circuit formation. READ MORE

  7. 20. Coagulase-negative staphylococci septicaemia in newborns : aspects on host-bacterial interactions with special regard to neutrophil and endothelial response

    Author : Maria Björkqvist; Stellan Håkansson; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : Newborn infants, especially those born preterm, are immunologically immature and prone to invasive infections. As a result of the increasing survival of very preterm (VPT < 31 weeks gestational age) newborns, nosocomial septicaemia has become a major concern the neonatal intensive care, and coagulase-negative staphylococci (CoNS) are nowadays the most frequently isolated pathogens in neonatal blood cultures.
