    Structure and conserved function of iso-branched sphingoid bases from the nematode Caenorhabditis elegans

    Hannich, J. Thomas ; Mellal, Denia ; Feng, Suihan ; Zumbuehl, Andreas ; Riezman, Howard

    In: Chemical Science, 2017, vol. 8, no. 5, p. 3676–3686

    Sphingolipids are bio-active metabolites that show structural diversity among eukaryotes. They are essential for growth of all eukaryotic cells but when produced in an uncontrolled manner can lead to cell death and pathologies including auto-immune reactions, cancer, diabetes and neurodegeneration. Caenorhabditis elegans is an important genetic model organism both to find new drug-targets...

    Exit-strategies – smart ways to release phospholipid vesicle cargo

    Mellal, Denia ; Zumbuehl, Andreas

    In: Journal of Materials Chemistry B, 2014, vol. 2, no. 3, p. 247–252

    This highlight describes recent trends in fundamental phospholipid research towards possible future drug delivery technology. In particular it focuses on synthetic phospholipids and their vesicular constructs and describes selected “smart” ways to release cargo from liposomes. Various chemical and physical release triggers are discussed such as temperature changes, application of ultrasound,...
