  2. 1. Effects of invasin and YopH of Yersinia pseudotuberculosis on host cell signaling

    Author : Anna Gustavsson; Maria Fällman; Arnoud Sonnenberg; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; β1-integrin; Yersinia pseudotuberculosis; Invasin; YopH; Cell-Matrix Adhesion; Filopodia; Cell Spreading; Molekylärbiologi; Molecular biology; Molekylärbiologi; molekylärbiologi; Molecular Biology;

    Abstract : Integrins are a large family of membrane-spanning heterodimeric (αβ) receptors that bind to ligands on other cells or to extracellular matrix (ECM) proteins. These receptors mediate bidirectional signaling over the cell membrane to induce signaling cascades mediating functions as cell adhesion, spreading and migration. READ MORE

  4. 2. The paralemmin protein family : Phosphoproteins involved in filopodia and dendritic spine formation

    Author : Nicole G. Neumann; Klas Kullander; Karin Nordström; Eirc Hanse; Uppsala universitet; []
    Keywords : ;

    Abstract : Dendritic spines, which connect neurons with each other, constitute most of the excitatory synapses and undergo experience-dependent neuronal plasticity. The function of dendritic spines and their synaptic strength are highly correlated with morphological changes. READ MORE

  5. 3. Water Fluxes and Cell Migration : How Aquaporin 9 Controls Cell Shape and Motility

    Author : Thommie Karlsson; Karl-Eric Magnusson; Roger Karlsson; Linköpings universitet; []
    Keywords : ;

    Abstract : Prerequisites for all modes of cell migration are cell-substratum interactions that require a sophisticated interplay of membrane dynamics and cytoskeletal rearrangement. Generally, a migrating cell is polarized with a distinct rear and front, from which it extends a wide and thin membrane protrusion- lamellipodium, small fingerlike projections- filopodia, and membrane blisters- blebs.

  6. 4. The N-methyl-D-aspartate receptor subunit NR3A : cloning, expression and interacting proteins

    Author : Maria Eriksson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : This thesis focuses on the subunit NR3A, which together with subunits NR1, NR2A-NR2D and NR3B builds the excitatory glutamate receptor N-methyl-D-aspartate (NMDA). The receptor is most likely a tetramer, containing at least one NR1, probably two NR2 and sometimes one NR3 subunit. READ MORE

  7. 5. Tumor angiogenesis. Regulation of mural cell recruitment and endothelial sprouting

    Author : Alexandra Abramsson; Göteborgs universitet; []
    Keywords : Angiogenesis; tumor; retina; PDGF; VEGF; platelet-derived growth factor; guidance; vascular endothelial growth factor.;

    Abstract : The formation of new blood vessels is an inherent part of many physiological and pathological processes. Currently, there is a strong hope pathological situations like stroke, diabetic retinopathy and cancer may be affected by pharmacological regulators of blood vessel formation. READ MORE
