  1. 1. Secondary Nucleation in Amyloid Formation

    Författare :Mattias Törnquist; NanoLund: Centre for Nanoscience; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Alzheimer s disease; amyloid; Ab42; aggregation mechanism; aggregation kinetics; secondary nucleation; Protein misfolding;

    Sammanfattning : Research into Alzheimer's disease is still hampered by a lack of fundamental understanding of the underlying mechanisms. While the aggregation of the amyloid β peptide (Aβ) into amyloid fibrils is highly implicated as a key factor in the disease, the molecular nature of its involvement has proven complex and elusive.

  2. 2. Systems Biology of the Secondary Metabolism in Filamentous Fungi

    Författare :Jens Christian Froslev Nielsen; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; genomics; systems biology; secondary metabolites; antibiotics; Next-generation sequencing; secondary metabolism; filamentous fungi; cell factories; Penicillium;

    Sammanfattning : Filamentous fungi constitute a rich reservoir of pharmaceutically relevant bioactive small molecules. These compounds, commonly referred to as secondary metabolites, are widely used as antibiotics for the treatment of microbial infections, but also as other pharmaceuticals such as immunosuppressors, cholesterol lowering agents and anticancer drugs.
