  2. 1. Cross-linked Profilin:actin - A tool to study actin dynamics in non-muscle cells

    Author : Staffan Grenklo; Roger Karlsson; Dan Lindholm; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; actin dynamics; profilin; actin; Profilin-actin complex; Cell motility; synaptic vesicle trafficing; Far western; fluorescence microscopy; Cell biology; Cellbiologi;

    Abstract : The microfilament system, consisting of actin and a number of auxiliary proteins, is fundamental for cell motility. Its dynamic organization depends on receptor-mediated signals, leading to rapid polymerizations and depolymerizations of actin. READ MORE

  4. 2. The Actin Filament System : Its Involvement in Cell Migration and Neurotransmitter Release

    Author : Anna-Karin Johnsson; Roger Karlsson; Stéphane Gasman; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Actin; Profilin; Synaptotagmin; Cell biology; Cellbiologi; Cell Biology; cellbiologi;

    Abstract : The microfilament system consists of actin filaments as the major component and is regulated by a number of actin binding proteins. It is juxtaposed to the plasma membrane where it forms a dense cortical weave from where it pervades into the cell interior. READ MORE

  5. 3. Vascular smooth muscle mechanotransduction and plasticity-the role of microRNA, calcium signaling and actin polymerization

    Author : Karolina Turczynska; Kärlfysiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; PYK2; actin polymerization; calcium; microRNA; stretch;

    Abstract : Smooth muscle cells residing in the blood vessel media are constantly exposed to mechanical forces exerted by the intraluminal pressure. The smooth muscle senses and adapts to mechanical forces by activation of multiple signaling pathways and cytoskeletal rearrangements. READ MORE

  6. 4. On the role of actin in yeast protein quality control

    Author : Lisa Larsson Berglund; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Protein quality control; Actin; Protein aggregate; Segregation; Polarisome; CCT; Huntingtin;

    Abstract : Every cell is equipped with a protein quality control system to ensure the proper function of proteins. This is essential for both cell maintenance and the generation of new and healthy cells. READ MORE

  7. 5. Plasma membrane order; the role of cholesterol and links to actin filaments

    Author : Jelena Dinic; Ingela Parmryd; Gerrit van Meer; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Membrane Organization; Lipid rafts; Actin; Laurdan; di-4-ANEPPDHQ; Cholesterol; T cell signaling; Colocalization; Generalized Polarization; Cell Biology; cellbiologi;

    Abstract : The connection between T cell activation, plasma membrane order and actin filament dynamics was the main focus of this study. Laurdan and di-4-ANEPPDHQ, membrane order sensing probes, were shown to report only on lipid packing rather than being influenced by the presence of membrane-inserted peptides justifying their use in membrane order studies.
