  2. 6. Endothelial Nitric Oxide in the Control of Glomerular Hemodynamics

    Author : János Pittner; Daniel H. Casellas; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell biology; Juxtamedullary nephron; afferent arteriole; nitric oxide; endothelial calcium; diaminofluoresceins; fura-2; autoregulation; shear stress; flow; videomicroscopy; Cellbiologi; Cell biology; Cellbiologi; Physiology; fysiologi;

    Abstract : The afferent arteriole of the kidney is a unique vascular segment: it is the effector of the renal hemodynamic autoregulation. The use of the isolated, perfused juxtamedullary nephron preparation makes it possible to visualize the afferent arteriole while preserving its tissue surroundings and the functional integrity of the nephron.

  4. 7. Cellular Origin and Development of Glioma

    Author : Nanna Lindberg; Lene Uhrbom; Bengt Westermark; Kristian Pietras; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Glioma; brain tumor; PDGF; RCAS TV-A; cell of origin; glial cell; oligodendrocyte progenitor cell; DNA repair; homology-directed repair; RAD51; angiogenesis; histidine-rich glycoprotein; Morphology; cell biology; pathology; Morfologi; cellbiologi; patologi; Molecular Medicine; molekylär medicin genetik och patologi ;

    Abstract : Gliomas are the most common primary tumors of the central nervous system believed to arise from glial cells. Invasive growth and inherent propensity for malignant progression make gliomas incurable despite extensive treatment. READ MORE

  5. 8. Roles of the Shb and Cbl Proteins in Signal Transduction and Blood Vessel Formation

    Author : Lingge Lu; Michael Welsh; Lars Holgren; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell biology; Shb; Cbl; FGF-2; NGF; PDGF; VEGF; VEGFR-2; differentiation; blood vessel formation; PC12 cells; endothelial cells; embryoid bodies; Rap1; CrkII; Cellbiologi; Cell biology; Cellbiologi; medicinsk cellbiologi; Medical Cell Biology;

    Abstract : Formation of blood vessels occurs through two processes: vasculogenesis and angiogenesis, which are regulated by various growth factors such as vascular endothelial growth factor, fibroblast growth factor and platelet-derived growth factor. The present study was carried out in order to investigate the roles of the Shb and Cbl proteins in growth factor-mediated signal transduction and blood vessel formation. READ MORE

  6. 9. Exploring Cellular Dynamics : From Vesicle Tethering to Cell Migration

    Author : Parham Ashrafzadeh; Johan Kreuger; Jonas Fuxe; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; angiogenesis; cancer; cell migration; exocyst complex; exocytosis; FGD5; lipid rafts; plasma membrane; receptor trafficking; VEGFR2;

    Abstract : Cells in the body communicate with each other in order to cooperate efficiently. This communication is in part achieved by regulated secretion of signaling molecules, which when released from a cell may activate receptors present at the plasma membrane of an adjacent cell. Such signals affect both cell fate and behavior. READ MORE

  7. 10. Talking to the Brain at the Blood-Brain Barrier through Inflammation-Induced Prostaglandin E2

    Author : Ana Maria Vasilache; Camilla Nilsberth; Sivert Lindström; Fredrik Elinder; Ted Ebendal; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The immune-to-brain signaling is a critical survival factor when the body is confronted by pathogens, and in particular by microorganisms. During infections, the ability of the immune system to engage the central nervous system (CNS) in the management of the inflammatory response is just as important as its ability to mount a specific immune response against the pathogen, since the CNS can provide a systemic negative feed-back to the immune activation by release of stress hormones and also can prioritize the usage of the energy resources by the vital organs.
