Glycosphingolipids as toxin receptors.

Abstract:

:A number of proteins produced by certain bacteria and plants are potently toxic to mammalian cells. This toxicity results from their ability to catalytically modify macromolecules that are required for essential cellular functions such as vesicular trafficking, cytoskeletal assembly, signalling or protein synthesis. To reach their targets, these proteins bind specific surface receptors before endocytosis and translocation across an internal membrane. The surface receptors exploited by different toxins include a range of proteins and lipids. Here we focus on specific glycosphingolipid receptors and two well-characterised subsets of toxins that exploit them for surface binding, intracellular trafficking, and signalling events.

  • Epidermal growth factor, from gene organization to bedside.

    abstract::In 1962, epidermal growth factor (EGF) was discovered by Dr. Stanley Cohen while studying nerve growth factor (NGF). It was soon recognized that EGF is the prototypical member of a family of peptide growth factors that activate the EGF receptors, and that the EGF/EGF receptor signaling pathway plays important roles in...
