  2. 1. Models of Retinal Development and Disease

    Author : Minas Hellsand; Finn Hallböök; Emma Andersson; Department of Cell and Molecular Biology Karolinska Institutet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Developmental neurobiology; retinal organoids; retinoblastoma; MYCN; Stargardt disease; Bardet-Biedl syndrome; model systems;

    Abstract : For a model of a human disease to be valid and useful, it is important that key genotypic and phenotypic traits are shared between model system and human. The work in this thesis has been focused on generating new and characterizing spontaneous models of three genetic disorders affecting the retina: retinoblastoma, a childhood cancer with its origin in the fetal retina, Stargardt disease, a juvenile form of macular degeneration, and Bardet-Biedl syndrome, a pleiotropic ciliopathy featuring retinal degeneration.

    Abstract : 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. READ MORE

  5. 3. Identification and characterization of nuclear envelope protein interactions

    Author : Balaje Vijayaraghavan; Einar Hallberg; Ing-Marie Nilsson; Bengt Mannervik; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Samp1; MCLIP; Nuclear envelope; Ran; Emerin; neurokemi med molekylär neurobiologi; Neurochemistry with Molecular Neurobiology;

    Abstract : The Nuclear envelope which surrounds the chromatin of eukaryotic cells contains more than a hundred transmembrane proteins. Mutations in some genes encoding nuclear envelope proteins give rise to human diseases including neurological disorders. The function of many nuclear envelope proteins is not well established.

  6. 4. Multifaceted roles of the transmembrane nuclear envelope protein, Samp1

    Author : Mohammed Hakim Jaffer Ali; Einar Hallberg; Giovanna Lattanzi; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Nuclear envelope; transmembrane protein interaction studies; cell differentiation; stem cells; myopathies; neurokemi med molekylär neurobiologi; Neurochemistry with Molecular Neurobiology;

    Abstract : The eukaryotic nuclear envelope (NE), separates the nucleoplasm from cytoplasm and is made up of two concentric lipid membranes, the outer and the inner nuclear membranes (ONM and INM), the nuclear pore complexes (NPCs) and an underlying filamentous nuclear lamina. The INM contains hundreds of unique transmembrane proteins of which only a handful have been characterized. READ MORE

  7. 5. Caspase activation in human neuroblastoma cells: mechanisms and spatiotemporal aspects

    Author : Elena V. Ivanova; Kerstin Iverfeldt; Boris Zhivotovsky; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; apoptosis; caspase; local caspase activation; neurodegeneration; tau-anchored FRET sensors; tAFS; cancer; neuroblastoma; TNF-related apoptosis inducing ligand; TRAIL; protein kinase C; PKC; X-linked inhibitor of apoptosis protein; XIAP; neurokemi med molekylär neurobiologi; Neurochemistry with Molecular Neurobiology;

    Abstract : Apoptosis is one of the modes of programmed cell death, in which several members of the caspase family of proteases play the central role. However, activation of apoptotic caspases does not necessarily lead to cell death. READ MORE
