  1. 11. Cell-penetrating peptide based nanocomplexes for oligonucleotide delivery

    Författare :Jakob Regberg; Ülo Langel; Arwyn Tomos Jones; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Cell-penetrating peptides; oligonucleotides; gene therapy; drug delivery; scavenger receptors; blood-brain barrier; neurokemi med molekylär neurobiologi; Neurochemistry with Molecular Neurobiology;

    Sammanfattning : Oligonucleotide-based drugs hold great promise for the treatment of many types of diseases, ranging from genetic disorders to viral infections and cancer. The problem is that efficient delivery across the cell membrane is required for oligonucleotides to have their desired effect. Cell-penetrating peptides (CPPs) provide a solution to this problem.

  3. 12. Cell-penetrating peptides, novel synthetic nucleic acids, and regulation of gene function : Reconnaissance for designing functional conjugates

    Författare :Peter Guterstam; Ülo Langel; Stockholms universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell-penetrating peptide; nucleic acids; alternative splicing; mismatch discrimination; Neurochemistry; Neurokemi;

    Sammanfattning : Our genome operates by sending instructions, conveyed by mRNA, for the manufacture of proteins from chromosomal DNA in the nucleus of the cell to the protein synthesizing machinery in the cytoplasm. Alternative splicing is a natural process in which a single gene can encode multiple related proteins. LÄS MER

  4. 13. Detection and quantification of lipid-mediated siRNA delivery to the cytosol

    Författare :Hampus Hedlund; Tumörmikromiljö; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; RNA Interference; RNA Therapeutics; Endosomal Escape; Lipid Mediated Delivery; Live-Cell Imaging;

    Sammanfattning : Cancer is one of the leading causes of death globally. Novel therapeutics is urgently needed to advance treatment, especially for generalized disease where current treatment options have a poor prognosis. In particular, targeted therapy that can address genetic changes would be of great value. LÄS MER

  5. 14. Endocytosis of therapeutic macromolecules in tumor cells - Mechanistic aspects of the proteoglycan receptor function

    Författare :Anders Wittrup; Bröstcancer-genetik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; LL-37; heparan sulfate; glypican; endocytosis; drug delivery; DNA uptake; Cancer; cell penetrating peptides; non-viral gene delivery; organelle purification; proteoglycan; syndecan.;

    Sammanfattning : Novel therapeutics to combat cancer are urgently needed. Most current pharmacological therapies have severe side effects and are seldom curative. Macromolecular drugs, and in particular nucleic acid based drugs, offer a potential remedy for this situation. LÄS MER

  7. 15. The development of synthetic gene delivery systems

    Författare :Lars J Brandén; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :gene transfer; synthetic vector; gene therapy; Bioplex; PNA; NLS;

    Sammanfattning : This thesis describes a new platform technology. The technique is referred to as Bioplex (biological complex) in analogy with the nomenclature for other transfection reagents, since we attach biological functions to a nucleic acid complex via sequence-specific hybridisation.
