  1. 11. Regulators of Membrane Fluidity

    Författare :Kiran Busayavalasa; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; PAQR; LRIG; membrane fluidity;

    Sammanfattning : Caenorhabditis elegans PAQR-2 (a homolog of the mammalian AdipoR1 and AdipoR2 proteins) and IGLR-2 (homolog of the mammalian LRIG proteins) form a complex at the plasma membrane that regulates fatty acid desaturation to protect against saturated fatty acid-induced membrane rigidification. Maintenance of membrane homeostasis is fundamental for most cellular processes and, given its importance, robust regulatory mechanisms must exist that adjust lipid composition to compensate for dietary variation.

  3. 12. Interaction Between Antimicrobial Peptides and Phospholipid Membranes : Effects of Peptide Length and Composition

    Författare :Lovisa Ringstad; Martin Malmsten; Per Hansson; Jeremy Ramsden; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Adsorption; antibacterial; antimicrobial peptide; bilayer; ellipsometry; electrochemistry; electrostatic interactions; hydrophobicity; liposome; membrane; monolayer; phospholipid; secondary structure; supported bilayer.; PHARMACY; FARMACI; Pharmaceutical Physical Chemistry; farmaceutisk fysikalisk kemi;

    Sammanfattning : Due to increasing problems with bacterial resistance development, there is a growing need for identifying new types of antibiotics. Antimicrobial peptides constitute an interesting group of substances for this purpose, since they are believed to act mainly by disrupting the bacterial membrane, which is a fast and non-specific mechanism.

  4. 13. Molecular properties of disordered plant dehydrins : Membrane interaction and function in stress

    Författare :Sylvia Eriksson; Pia Harryson; Steffen Graether; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; abiotic stress; dehydrin; intrinsically disordered proteins; Lea-proteins; phospholipids; Biochemistry; biokemi;

    Sammanfattning : Dehydrins are intrinsically disordered plant stress-proteins. Repetitively in their sequence are some highly conserved stretches of 7-17 residues, the so called K-, S-, Y- and lysine rich segments. LÄS MER

  5. 14. Probing and elucidating the dynamics of virus-membrane interaction via plasma membrane mimics

    Författare :Konrad Thorsteinsson; Marta Bally; Hudson Pace; Gisa Gerold; Susan Daniel; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Plasma membrane; supported lipid bilayer; binding kinetics; equilibrium fluctuation analysis; TIRF; FRET; norovirus; HSV; SARS-CoV-2; histo-blood group antigens; ApoE; heparan sulfate; mikrobiologi; Microbiology;

    Sammanfattning : Virus infection is initiated by the attachment of a virion to a susceptible cell’s plasma membrane, in a highly dynamic and well-orchestrated process that encompasses various steps and engages numerous viral and cellular factors. These dynamic steps may include initial non-specific binding to ubiquitous cell-membrane ligands, diffusion across the membrane to a suitable entry site and virus engagement with various receptors and co-receptors on the cell surface.
