  1. 1. Cholesterol in T cells : homeostasis, plasma membrane organization and signaling

    Författare :Saleemulla Mahammad; Ingela Parmryd; Thomas Harder; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Plasma membrane; T cells; Cholesterol; Lipid rafts; Membrane organization; Cholesterol homeostasis; cholesteryl esters; Cell biology; Cellbiologi; Cell Biology; cellbiologi;

    Sammanfattning : The plasma membrane of eukaryotic cells contains cholesterol and glycosphingolipids enriched nanodomains known as lipid rafts; which are believed to exist in a liquid ordered (lo) state. Methyl-beta-cyclodextrin (MBCD) is used to deplete cellular cholesterol and a widespread assumption is that MBCD preferentially targets cholesterol in lipid rafts. LÄS MER

  3. 2. Cell Membrane Homeostasis in Mammals - The roles of ADIPOR2 and TLCD1 & 2

    Författare :Henrik Palmgren; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Membrane lipids; Membrane fluidity; Membrane homeostasis; Dietary lipids; Phospholipids; Genetics; Lipotoxicity; Lipidomics; ADIPOR2; TLCD1; TLCD2;

    Sammanfattning : Ten nanometers. That is the approximate thickness of the plasma membrane that separates the extracellular space from the entire cellular machinery. An asymmetrical bilayer consisting of predominantly phospholipids in which proteins and carbohydrates are anchored and exert their function. LÄS MER

  4. 3. Membrane morphology and homeostasis: An electron microscopy approach

    Författare :Dimitra Panagaki; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; nuclear envelope bud; AdipoR2; membrane homeostasis;

    Sammanfattning : Biological membranes allow life as we know it to exist. Primarily assembled from lipids and proteins, their morphology and function can greatly vary between species or even within the same cell. They create physical boundaries, separating different cells from each other and forming functional compartments within the cells. LÄS MER

  5. 4. Membrane Fluidity Regulation: From C. elegans to mammalian cells

    Författare :Ranjan Devkota; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PAQR-2; adiponectin receptors; IGLR-2; saturated fats; membrane fluidity; fatty acid desaturation; unsaturated fatty acid; membrane homeostasis;

    Sammanfattning : Biological membranes are primarily an assembly of lipids and proteins. Collectively, these constituents within a phospholipid bilayer determine the physical membrane properties such as fluidity, viscosity, thickness, packing and permeability. Maintenance of membrane properties within acceptable margins, i.e. LÄS MER

  7. 5. Pathogen entry mechanisms and endocytic responses to plasma membrane damage

    Författare :Lars Nygård Skalman; Richard Lundmark; Kristian Riesbeck; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Endocytosis; plasma membrane; pathogens; virus; bacterial membrane vesicles; Helicobacter pylori; adenovirus 37; listeriolysin O; pore-forming toxins; membrane repair;

    Sammanfattning : Endocytosis is a fundamental cellular process by which cells transport material from the outside to the inside of the cell through the formation of membrane invaginations that bud off from the plasma membrane. This process is important for nutrient uptake, regulating cell surface receptors and the overall plasma membrane composition. LÄS MER
