  2. 16. Molecular regulation of somatosensory neuron development

    Author : Yiqiao Wang; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The somatosensory system of vertebrates perceives and transmits a variety of information from both external and internal environments to the central nervous system where an integrated response is established leading to adaptive outcome. Specific classes of sensory neurons convey the information consisting of touch, muscle stretch, temperature, itch, and pain. READ MORE

  4. 17. Glypican-1: Structural and functional analysis of the N-glycosylated human protein

    Author : Wael Awad Abdelhady; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Proteoglycans; glypicans; glypican-1; heparan sulphate; N-glycosylation; exostosin-proteins; X-ray crystallography; crystal dehydration; diffraction anisotropy; Small angle X-ray scattering SAXS9; protein spectroscopy;

    Abstract : Glypicans are multifunctional cell surface heparan sulphate proteoglycans co-regulating numerous signalling pathways, and are thereby involved in the control of cellular division, differentiation, and morphogenesis. The heparan sulphate (HS) chains are responsible for many of those biological functions; nevertheless recent studies suggest functional roles for the glypican core proteins in mediating the signalling of various growth factors.

  5. 18. Human Embryonic Stem Cells: Directed Differentiation into Posterior Foregut Endoderm and a Functional Assay for Definitive Endoderm

    Author : Martina Johannesson; Immunologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : A decade has passed since the first human embryonic stem cell (hESC) line was established, providing immense hope in curing diseases by cell replacement therapy. For instance, in the pancreas, the insulin-producing β-cells are damaged in diabetes patients, and a successful replacement of those cells could provide a cure. READ MORE

  6. 19. The role of transcriptional repression in Shh signalling and patterning of the ventral neural tube

    Author : Madelen Persson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : From flies to humans, members of the Hedgehog (Hh) family of secreted signalling molecules play a vital role in determining cell fate and patterning during embryonic development. In vertebrates, Sonic Hedgehog (Shh) act in a graded manner to establish distinct neural progenitor populations at different concentration thresholds in the ventral neural tube. READ MORE

  7. 20. Transcriptional regulation of thyroid development possible interplay of endoderm- and mesoderm-derived morphogenetic signals

    Author : Jessica Westerlund; Göteborgs universitet; []
    Keywords : thyroid; congenital hypothyroidism; dysgenesis; Tbx1; Shh; Isl1; Foxa2; C-cells;

    Abstract : Congenital hypothyroidism (CH) affects 1 in 3000 children and is the major cause of treatable mental retardation. Most cases are due to malformations of the gland, collectively named thyroid dysgenesis. The disease results from defective thyroid organogenesis during embryonic life. READ MORE
