  2. 11. In-silico design of peptide-based transfection systems, in-vitro validation, and up-take pathways investigation

    Author : Moataz Dowaidar; Ülo Langel; IngMarie Nilsson; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Cell-penetrating peptides; QSAR; PepFect; neurokemi med molekylär neurobiologi; Neurochemistry with Molecular Neurobiology;

    Abstract : Cell-penetrating peptide-based transfection systems (PBTS) are a promising group of drug delivery vectors. Cell-penetrating peptides (CPPs) are short cationic peptides that are able of transporting cell non-permeant cargos into different cell types. READ MORE

  4. 12. Gene therapy tools: oligonucleotides and peptides

    Author : Jonas Eriksson; Ülo Langel; Jens Kurreck; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Gene therapy; oligonucleotide; peptide; RNA-cleaving deoxyribozyme; deoxyribozyme; DNAzyme; cell-penetrating peptide; CPP; enzyme; enzyme kinetics; kinetic assay; assay; telomerase; telomerase inhibitor; imetelstat; GRN163L; neurokemi med molekylär neurobiologi; Neurochemistry with Molecular Neurobiology;

    Abstract : Genetic mutations can cause a wide range of diseases, e.g. cancer. Gene therapy has the potential to alleviate or even cure these diseases. READ MORE

  5. 13. Oligonucleotide Complexes with Cell-Penetrating Peptides : Structure, Binding, Translocation and Flux in Lipid Membranes

    Author : Luis Daniel Ferreira Vasconcelos; Ülo Langel; Tore Bengtsson; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cell-penetrating peptide; Large unilamellar vesicle; Membrane perturbation; Endosomal escape; neurokemi med molekylär neurobiologi; Neurochemistry with Molecular Neurobiology;

    Abstract : The ability of cell-penetrating peptides to cross plasma membranes has been explored for various applications, including the delivery of bioactive molecules to inhibit disease-causing cellular processes. The uptake mechanisms by which cell-penetrating peptides enter cells depend on the conditions, such as the cell line the concentration and the temperature. READ MORE

  6. 14. The role of nuclear membrane proteins in differentiation and chromatin organization

    Author : Cecilia Bergqvist; Einar Hallberg; Neus Visa; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; nuclear membrane proteins; chromatin organization; epigenetics; differentiation; stem cells; neurokemi med molekylär neurobiologi; Neurochemistry with Molecular Neurobiology;

    Abstract : The nuclear envelope, consisting of an outer and an inner nuclear membrane, surrounds the genomic material. The genomic material (chromatin) is highly structured with (transcriptionally inactive) heterochromatin mostly found in the nuclear periphery and (transcriptionally active) euchromatin mostly found in the nuclear interior.

  7. 15. The amyloid-β precursor protein (APP) and its adaptor protein Fe65 : Two key players in Alzheimer’s disease

    Author : Preeti Menon; Anna-Lena Ström; Thorsten Müller; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Alzheimer s disease; APP; Fe65; Meprinβ; α-secretase; APP processing; neurokemi med molekylär neurobiologi; Neurochemistry with Molecular Neurobiology;

    Abstract : Alzheimer’s disease (AD) is a neurodegenerative disease characterized by the abnormal accumulation and aggregation of amyloid beta (Aβ) peptides within the brain. Generation of Aβ occur when the amyloid-beta precursor protein (APP) is proteolytically processed by β- and then γ-secretase in the amyloidogenic pathway. READ MORE
