  1. 1. Angiostatic treatment of neuroblastoma

    Författare :Erik Wassberg; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell biology; Angiogensis; Angiostatic treatment; Apoptosis; Chromogranin A; Differentiation; Neuroblastoma; 2-Methoxyestradiol; 2-Propynylestradiol; TNP-470; Cellbiologi; Cell biology; Cellbiologi; medicinsk cellbiologi; Medical Cell Biology;

    Sammanfattning : Neuroblastoma is a malignant solid tumor of childhood with a poor prognosis. The growth of solid tumors has been shown to be dependent on new blood vessel formation, i.e. angiogenesis. LÄS MER

  3. 2. Studies of molecular events during peripheral B cell differentiation

    Författare :Jens Wrammert; Immunologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; transplantation; Immunologi; serologi; serology; Immunology; B cells; Differentiation;

    Sammanfattning : This thesis focuses on molecular changes occuring during terminal B cell differentiation as well as on somatic hypermutation and the generation and maintenance of B cell memory. During T cell dependent immune responses the average affinity for the eliciting antigen increases with time. LÄS MER

  4. 3. Device Bonding and Antibody Binding: Developments for On-Chip Differentiation of Induced Pluripotent Stem Cells into Hepatocytes

    Författare :Philip Dalsbecker; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Microfluidics; liver-on-a-chip; organ-on-chip; PDMS; oxygen plasma; immunofluorescence; fluorescence microscopy; hepatocytes; iPSC; induced pluripotent stem cells; differentiation; on-chip differentiation; definitive endoderm;

    Sammanfattning : Abstract This thesis describes the bonding optimization of a liver-on-a-chip microfluidic device for evaluation of cultured induced pluripotent stem cell (iPSC)-derived definitive endoderm (DE) cells during their targeted differentiation into mature hepatocytes. Furthermore, it describes the optimization of a number of antibody assays for use during said differentiation, for the purpose of studying the cellular phenotype. LÄS MER

  5. 4. Regulation of B cell development by antigen receptors

    Författare :Jannek Hauser; Thomas Grundström; Yuan Zhuang; Umeå universitet; []
    Nyckelord :calcium; calmodulin; e-proteins; E2A; B cell development; antigen receptor signaling; surrogate light chains; RAG; allelic exclusion; V D J recombination; AID; negative feedback regulation; plasma cell differentiation;

    Sammanfattning : The developmental processes of lymphopoiesis generate mature B lymphocytes from hematopoietic stem cells through increasingly restricted intermediates. Networks of transcription factors regulate these cell fate choices and are composed of both ubiquitously expressed and B lineage-specific factors. LÄS MER

  7. 5. Novel roles of ErbB3 receptor tyrosine kinase in vesicular trafficking

    Författare :Ana Rosa Saez-Ibañez; Ingvar Ferby; Carl-Henrik Heldin; Johanna Ivaska; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ErbB3; Integrin; GGA3; Rabaptin5; PKD; Ack1; endocytic recycling; exosome; Biology with specialization in Molecular Cell Biology; Biologi med inriktning mot molekylär cellbiologi;

    Sammanfattning : ErbB3 is a catalytically impaired receptor tyrosine kinase (RTK) from the EGFR family. Upon ligand binding, ErbB3 forms heterodimers with other members of the family and triggers phosphorylation cascades that promote crucial cellular functions as proliferation, differentiation and survival.
