  1. 21. Direct Conversion of Human Fibroblasts to Induced Neurons

    Author : Ulrich Pfisterer; Utvecklings- och regenerativ neurobiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cellular Reprogramming; Direct Conversion; Human Induced Neurons; Dopaminergic; Cell Replacement Therapy; Lentiviral Vectors;

    Abstract : During direct cellular reprogramming, forced expression of key transcription factors (TFs) directly converts one terminally differentiated cell type into that of another fate, exemplified in this theses by the conversion of fibroblasts into functional induced neurons (iNs). Direct conversion of mouse fibroblasts to functional neurons was established in 2010, and the starting point of my doctoral thesis was the aim to transfer iN-technology to human cells and to explore the potential of this technique in regards to generate subtype-specific neurons as well as to use these cells for transplantation studies.

  2. 22. Semliki forest virus-derived packaging system for production of retroviral vectors

    Author : Ke-Jun Li; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Moloney murine leukemia virus; Semliki Forest virus; gene therapy; retroviral vector; intron; human bone marrow stromal cell;

    Abstract : Gene therapy is a treatment of disease by transfer of genetic material into somatic cells of an individual. Successful gene therapy depends on a delivery system which can efficiently transfer the gene into target cells and lead to high level expression of the gene. READ MORE

  3. 23. Enhancing the efficiency of viral and non-viral gene delivery vectors

    Author : Safa Bazaz; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Gene therapy, which involves the introduction, alteration, or deletion of genetic material within cells to treat or prevent disease, holds great promise for addressing various genetic disorders and other medical conditions. However, several challenges remain in the field, particularly concerning nucleic acid delivery into target cells. READ MORE

  4. 24. Restorative and neuroprotective treatment strategies for Parkinson’s disease: tudies on fetal dopamine cell transplants and GDNF delivery by intracerebral injections and recombinant AAV vectors

    Author : Deniz Kirik; Neurobiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; adeno-associated virus; regeneration; neuroprotection; glial-cell-line-derived-neurotrophic factor; cell death; substantia nigra; dopamine; neurofysiologi; neuropsykologi; Neurologi; neurophysiology; neuropsychology; Neurology; tyrosine hydroxylase; sensorimotor behavior; transplantation; gene therapy;

    Abstract : The intrastriatal 6-hydroxydopamine lesion model in rats is particularly useful in studies testing new therapeutic strategies for Parkinson’s disease. This thesis work (1) describes the characterization of the motor deficits after different types of intrastriatal lesions and identifies the four-site terminal lesion as a model of symptomatic Parkinson’s disease; (2) using the same model, provides evidence that the functional impact of the dopamine cell grafts are dependent on interactions with the host brain; (3) demonstrates that protection or restitution of normal motor function after 6-hydroxydopamine lesions can be achieved if glial cell line-derived neurotrophic factor is administered in the striatum at the time of the terminal fiber degeneration.

  5. 25. Modeling Diamond-Blackfan Anemia in the Mouse: Disease Pathogenesis and Evaluation of Novel Therapies

    Author : Pekka Jaako; Avdelningen för molekylärmedicin och genterapi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : Diamond-Blackfan anemia (DBA) is a congenital erythroid hypoplasia that presents early in infancy. The main hematopoietic symptoms include macrocytic anemia with reticulocytopenia and selective absence of erythroid precursors in a normocellular bone marrow. READ MORE
