    Sammanfattning : Spinocerebellar Ataxia type 7 (SCA7) is a genetic neurodegenerative disease with lethal outcome that affects the cerebellum and retina of patients. This thesis focuses on characterising molecular pathological pathways that cause toxicity and cell death in SCA7. LÄS MER

  3. 2. Cell-penetrating peptides in protein mimicry and oligonucleotide delivery : Applications and mechanisms

    Författare :Henrik Johansson; Ülo Langel; Michael Gait; Stockholms universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; peptide; oligonucleotide; cell-penetrating peptide; PNA; splicing; Neurochemistry; Neurokemi; Neurochemistry and Molecular Neurobiology; neurokemi med molekylär neurobiologi;

    Sammanfattning : The plasma membrane functions as a barrier, restricting entry of hydrophilic pharmaceutical agents. Cell-penetrating peptides (CPPs) are capable of transporting bioactive cargos into the cell and have consequently been extensively investigated for their mechanism of entry and capability to deliver various cargos spanning from peptides to plasmids.

  4. 3. Cell-penetrating peptides as delivery vectors for oligonucleotides and proteins : Studies on applications and toxicity

    Författare :Peter Järver; Ülo Langel; Gilles Divita; Stockholms universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurochemistry; Neurokemi; neurokemi med molekylär neurobiologi; Neurochemistry with Molecular Neurobiology;

    Sammanfattning : Cell-penetrating peptides (CPPs) have for a little bit more than a decade been employed as delivery vectors for a wide range of cargoes, ranging from gold particles to entire plasmids. Although CPP are well studied and utilized in numerous publications, our knowledge about CPP mediated transport is still poor. LÄS MER

  5. 4. Oxidative stress and alterations in the mammalian iron metabolism : A study on iron, inflammation, oxidative stress and neurodegeneration

    Författare :Jonas Hälldin; Tiit Land; Paolo Arosio; Stockholms universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurochemistry; Neurokemi; Neurochemistry and Molecular Neurobiology; neurokemi med molekylär neurobiologi;

    Sammanfattning : Iron is essential for all living organisms, from bacteria to man for a broad variety of biological functions, including oxygen transport and DNA synthesis. However, iron can also be toxic, due to its involvement in the formation of highly reactive oxygen species through Fenton chemistry. LÄS MER

  7. 5. Activation and Regulation of TRPV1 : Studies in Recombinant Human Neuroblastoma TRPV1-SHSY5Y Cells

    Författare :Johanna EL Andaloussi-Lilja; Anna Forsby; Antonio Ferrer-Montiel; Stockholms universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; nociception; neurotrophic factors; eye irritation; stable transfection; Ca2 ; Neurochemistry; Neurokemi; Neurochemistry and Molecular Neurobiology; neurokemi med molekylär neurobiologi;

    Sammanfattning : TRPV1 is a transmembrane non-selective cation channel with preference for Ca2+. The receptor is primarily localised on dorsal root ganglion neurons and is activated by numerous endogenous and exogenous potentially irritating ligands eliciting pain. LÄS MER
