1. 1. Glucocorticoid in T cell differentiation

   Författare :Yintong Xue; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Thymocytes differentiate into mature T cells with an immunological restriction for self major histocompatibility complex (MHC) antigens. Cells that do not recognize self MHC expressed on thymic epithelial cells (TEC) die by a rapid induction of apoptosis (default selection). LÄS MER

3. 2. Protein Damage Control during Embryonic Stem Cell Differentiation: Role of the Proteasome

   Författare :Malin Hernebring; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Embryonic Stem Cells; Proteasome; Protein Carbonylation; Advanced Glycation End products; Cell Differentiation; Oxidative stress; Aging; RNAi;

   Sammanfattning : During the lifespan of organisms ranging from yeast to humans, there is an accumulation of macromolecular damage. However, these organisms produce youthful progeny with low damage levels. This thesis focuses on how this is accomplished. LÄS MER

4. 3. Molecular Mechanisms in Endothelial Cell Differentiation

   Författare :Emma Rennel; Pär Gerwins; Lena Claesson-Welsh; Ian Zachary; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pathology; angiogenesis; FGF-2; VEGF-A; signal transduction; in vitro angiogenesis assay; immortalized brain endothelial cells; H-Ras; tetracycline-regulated gene expression; microarray; telomerase immortalized human microvascular endothelial cells; differentiation; Patologi; Pathology; Patologi;

   Sammanfattning : Angiogenesis is the formation of new blood vessels from the pre-existing blood vessels. Blood vessels are composed of endothelial cells and supporting musculature. Angiogenesis is regulated by numerous soluble ligands and by cell-matrix interactions. LÄS MER

7. 5. Neural Stem Cell Differentiation and Migration

   Författare :Anna Erlandsson; Karin Forsberg-Nilsson; Bengt Westermark; Christer Betsholtz; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicine; CNS; stem cells; neuron; PDGF; SCF; differentiation; migration; ERK; Medicin; Dermatology and venerology; clinical genetics; internal medicine; Dermatologi och venerologi; klinisk genetik; invärtesmedicin; Medicinsk biokemi; Medical Biochemistry;

   Sammanfattning : Neural stem cells are the precursors of neurons, astrocytes and oligodendrocytes. During neural development, the division of stem cells takes place close to the lumen of the neural tube, after which they migrate to their final positions within the central nervous system (CNS).
