  1. 1. Molecular and functional anatomy of the mouse olfactory epithelium

    Författare :Viktoria Vedin; Anna Berghard; Urban Lendahl; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; olfactory epithelium; odorant receptor; zone; odorant; gene expression; cell specification; c-Fos; dichlobenil; olfactometry; proliferation; Molecular biology; Molekylärbiologi;

    Sammanfattning : The olfactory system is important for social behaviors, feeding and avoiding predators. Detection of odorous molecules is made by odorant receptors on specialized sensory neurons in the olfactory epithelial sheet. LÄS MER

  3. 2. The Role of Lhx2 During Organogenesis : - Analysis of the Hepatic, Hematopoietic and Olfactory Systems

    Författare :Åsa Kolterud; Leif Carlsson; Stefan Thor; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; LIM-homeobox gene; Lhx2; fetal liver; hepatic stellate cells; hematopoietic stem cells; septum transversum; self-renewal; odorant receptor genes; olfactory epithelium; olfactory sensory neuron; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi; molekylärbiologi; Molecular Biology;

    Sammanfattning : During embryonic development a variety of tissues and organs such as the lung, eye, and kidney are being formed. The generation of functional organs is regulated by reciprocal cell-cell interactions. Via the secretion of soluble molecules one type of cells affect the fate of their neighboring cells. LÄS MER

  4. 3. Structure and Function of Odorant Binding Proteins and Chemosensory Proteins in Moths

    Författare :Severine Jansen; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NMR structure; Ecology; Ekologi; Development; Lepidoptera; Odorant Binding Proteins; Chemosensory Proteins;

    Sammanfattning : Odorant Binding Proteins (OBPs) and Chemosensory Proteins (CSPs) are small soluble proteins found in the lymph of insect sensillae located on insect antennae. Odorant Binding proteins are implied in olfaction, by binding hydrophobic odorant molecules and transporting them to the olfactory receptor located on the dendrite of the olfactory neurons. LÄS MER

  5. 4. Regulatory mechanisms in olfactory system assembly and function

    Författare :Carolyn Marks; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The mammalian sense of smell relies on the detection of odorants by a large family of G protein coupled receptors, encoded by ~1300 different genes in mice (Buck and Axel, 1991; Zhang et al., 2007). These odorant receptors (ORs) are expressed in olfactory sensory neurons (OSNs) in the main olfactory epithelium (MOE). LÄS MER

  7. 5. Chemosensation in Aedes aegypti: from molecular response profiles to host-seeking behaviour

    Författare :Anaïs Tallon; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The female mosquito Aedes aegypti is the primary urban vector of various highly infectious neglected tropical diseases. Disease transmission relies heavily on odourmediated behaviours, including e.g., sugar- and host-seeking, which are crucial during the mosquito life cycle and has dire impacts on vectorial capacity.
