  2. 1. Characterization of artificial and biological lipid vesicles using TIRF and SPR

    Author : Thomas Olsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; membrane permeability; chromaffin vesicle; fluorescence; total internal reflection TIRF microscopy; surface plasmon resonance SPR ; vesicle; osmotic shock; cell membrane; liposome; nanoparticle tracking analysis NTA ; large dense core vesicles LDCVs ;

    Abstract : Synthetic lipid vesicles serve as important mimics of cells and the natural membranes that they are enclosed by. As such they are frequently used as simplified models of the highly complex cell membrane to aid in-depth physicochemical and biological characterization of this essential biological structure.

  4. 2. Interaction of Calcium Ions with Lipid Membranes

    Author : Baharan Ali Doosti; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; phospholipid bilayer membrane; membrane dynamics; micromanipulation; calcium ions; cell migration.; membrane nanotube; membrane tubular protrusions; calcium ion concentration gradient; membrane bending; giant unilamellar vesicle;

    Abstract : Bilayer membranes enclose and shield the biological cell and its inner compartments, as well as the tubular networks that exist within and between the cells. Due to their fluidic nature, the membranes are incredibly dynamic and flexible, which allows them to bend, reshape and fuse in response to mechanical and chemical stimuli within their natural microenvironments.

    Abstract : Within life science, there is currently an intense search for novel techniques that enable efficient and reliable analysis of biomolecular interactions. Such methods have future applications within medical diagnostics and drug development, as well as within proteomic research in general. READ MORE

  6. 4. The cell biology and catalytic properties of the nutrient-induced signaling endoprotease Ssy5

    Author : António Martins; Per O. Ljungdahl; Bruno André; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nutrient sensing; signal transduction; regulated proteolysis; endoprotease; serine protease; substrate specificity; subcellular fractionation; Saccharomyces cerevisiae; Cell Biology; cellbiologi;

    Abstract : Cells continuously sense and respond to changes in the presence, quality and quantity of external and internal nutrients. Specific signaling proteases have been identified based on their roles in processing or destruction of distinct sets of downstream effector proteins in response to environmental cues. READ MORE

  7. 5. Drug Partitioning into Natural and Artificial Membranes : Data Applicable in Predictions of Drug Absorption

    Author : Caroline Engvall; Birgitta Tomkinson; Katarina Edwards; Sven Engström; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Bilayer disk; Cholesterol; Drug partitioning; Drugs; Electrostatic effects; Immobilized liposome chromatography; Liposome; Membrane protein; Model membrane; Oligonucleotide-liposome complex; Phospholipid; Phospholipid bilayer; Proteoliposome; Surfactant; Biokemi; Biochemistry; Biokemi;

    Abstract : When drug molecules are passively absorbed through the cell membrane in the small intestine, the first key step is partitioning of the drug into the membrane. Partition data can therefore be used to predict drug absorption. READ MORE
