  2. 1. Signal Transduction in Photoreceptor Proteins : Insights From Time-Resolved X-ray Solution Scattering

    Author : Oskar Berntsson; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Signal transduction; Photoreceptor; Time-resolved X-ray solution scattering; Protein dynamics; Phytochrome; Light-oxygen-voltage; Cryptochrome;

    Abstract : The ability to sense and react to different light conditions is of great importance for many organisms on the face of the earth. Specialized proteins known as photoreceptor proteins provide bacteria, plants and animals with this ability. READ MORE

  4. 2. ß2 integrin-induced signal transduction events in human neutrophils

    Author : Fredrik Melander; Malmö Experimentell patologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Inflammation; integrins; signal transduction; Rho GTPases; kinases; c-Cbl; General pathology; patologisk anatomi; pathological anatomy; Patologi allmän ; neutrophils;

    Abstract : Inflammation is a localized protective response in vascularized tissues and can be induced by microbial infection or cell and tissue injury. Polymorphonuclear neutrophils (PMN) are the most common white blood cells and are recognized as major cellular mediators of acute inflammation. READ MORE

  5. 3. Adaptive Responses by Transcriptional Regulators to small molecules in Prokaryotes : Structural studies of two bacterial one-component signal transduction systems DntR and HpNikR

    Author : Cyril Dian; Peter Brzezinski; Séan McSweeney; Elisabeth Sauer-Eriksson; Stockholms universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; transcription regulator; bacterial biosensor; LysR family; Inducer-binding; nickel-sensing; NikR; signal transduction system; Helicobacter pylori; Biochemistry; Biokemi; biokemi; Biochemistry;

    Abstract : Prokaryotes are continually exposed to variations in their environment. Survival in unstable milieu requires a wide range of transcriptional regulators (TRs) that respond to specific environmental and cellular signals by modulating gene expression and provide an appropriate physiological response to external stimuli.

  6. 4. Fibroblast growth factor-induced signal transduction

    Author : Peter Klint; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; Biokemi; Biochemistry; Biokemi; molekylär cellbiologi; Molecular Cellbiology;

    Abstract : Fibroblast growth factors (FGFs) evoke cellular responses by binding to FGF receptors (FGFRs). FGFRs are cell surface expressed membrane-spanning receptors with intrinsic stimulatable tyrosine kinase activity. This thesis describes the cell proliferation or differentiation. READ MORE

  7. 5. Stem Cell Factor Induced Signal Transduction

    Author : Johan Lennartsson; Christer Larsson; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Oncology; Onkologi; Oncology; Onkologi; molekylär cellbiologi; Molecular Cellbiology;

    Abstract : Stem Cell Factor (SCF) can function as a survival factor, a mitogen or a chemoattractant depending on cell type. Binding of SCF to c-Kit induces dimerization and subsequent autophosphorylation of the receptor. This thesis describes the intracellular signal transduction elicited by c-Kit. READ MORE
