  1. 1. Airway epithelial shedding: Morphological and functional aspects in vivo

    Författare :Jonas Erjefält; Luftvägsinflammation; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; eosinophils; neutrophils; plasma exudation; barrier restitution; basal cells; ciliated cells; secretory cells; Epithelial repair; epithelial shedding; fibrinogen; fibronectin; Respiratory system; Andningsorganen;

    Sammanfattning : Epithelial damage may contribute to the pathology in airway diseases such as asthma and rhinitis. However, the distribution of epithelial shedding in inflammatory airway diseases and, particularly, the ensuing repair processes are largely unknown. LÄS MER

  3. 2. Grainy head target genes in epithelial morphogenesis and wound healing

    Författare :Shenqiu Wang; Christos Samakovlis; Paul Martin; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; grh; targets; epidermal wound repair; tracheal tube size control; local immune responses; stit; verm; serp; PGRP-LC; CecA-LacZ; Developmental biology; Utvecklingsbiologi; utvecklingsbiologi; Developmental Biology;

    Sammanfattning : grainy head (grh) genes encode a family of transcription factors conserved from fly to human. Drosophila grh is the founding member of this gene family and has multiple functions, including tracheal tube size control, epidermal barrier formation and reconstruction after wounding. LÄS MER

  4. 3. Pathogen entry mechanisms and endocytic responses to plasma membrane damage

    Författare :Lars Nygård Skalman; Richard Lundmark; Kristian Riesbeck; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Endocytosis; plasma membrane; pathogens; virus; bacterial membrane vesicles; Helicobacter pylori; adenovirus 37; listeriolysin O; pore-forming toxins; membrane repair;

    Sammanfattning : Endocytosis is a fundamental cellular process by which cells transport material from the outside to the inside of the cell through the formation of membrane invaginations that bud off from the plasma membrane. This process is important for nutrient uptake, regulating cell surface receptors and the overall plasma membrane composition. LÄS MER

  5. 4. Characterization of Retinal Progenitor Cells : Focus on Proliferation and the GABAA Receptor System

    Författare :Henrik Ring; Finn Hallböök; Per Söderberg; Andras Simon; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Regeneration; Proliferation; Neurotransmitters; Müller cells; Differentiation; Retinal repair; Neurogenesis; Medical Science; Medicinsk vetenskap;

    Sammanfattning : One strategy to repair an injured or degenerated retina is to stimulate the replacement of damaged or dead neurons with cells derived from endogenous stem- or progenitor cells. A successful strategy requires knowledge about how the proliferation and differentiation of the endogenous cells are regulated. LÄS MER

  7. 5. The role of PDGF-A in lung development, injury and repair

    Författare :Leonor Gouveia; Johanna Andrae; Christer Betsholtz; Brigid Hogan; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Lung; organogenesis; PDGF; signalling pathway; development;

    Sammanfattning : The developmental processes that take place during embryogenesis depend on a great number of proteins that are important for cell-to-cell communication. Platelet-derived growth factors are known to be important for epithelial-mesenchymal interactions during development and organogenesis. LÄS MER
