  1. 1. Effects of retinoic acid in the mouse olfactory sensory systems

    Author : Maria Hörnberg; Staffan Bohm; Finn Hallböök; Umeå universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; olfactory; retinoic acid; neuron survival; Molecular biology; Molekylärbiologi;

    Abstract : A common characteristic in neurodegenerative diseases of the brain is death of specific neuronal populations. The lack of neuron proliferation and axon extension in most parts of the central nervous system leads to chronic loss of neurons in the case of injury or disease. READ MORE

  2. 2. From sequence to function : Comparative studies of insect olfactory receptors

    Author : Xiaoqing Hou; Funktionell zoologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Olfactory receptor; Heterologous expression; Pheromone; Plant volatile; Insect;

    Abstract : In insects airborne odors are detected by the odorant receptors (ORs) and ionotropic receptors (IRs), located on the dendritic membrane of the olfactory sensory neurons (OSNs) housed in olfactory sensilla. The OR and IR gene families show high plasticity in lineage expansion and contraction following the birth-and-death evolutionary model. READ MORE

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

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

    Abstract : 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. READ MORE

  4. 4. Insights into the Evolution of Moth Pheromone Communication: Lessons from the European Corn Borer

    Author : Jean-Marc Lassance; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; biosynthetic enzymes; evolution; Ostrinia nubilalis; mate choice; mate finding; olfaction; biosynthesis; speciation; moth; pheromone; olfactory receptors.;

    Abstract : Chemical communication by means of sex pheromones is central to the mating systems of a wide range of organisms. Because reproductive isolation is often based on pheromone differences, understanding how pheromones diverge is necessary for a complete comprehension of the speciation process. READ MORE

  5. 5. Factors influencing the turnover of olfactory receptor neurons

    Author : Maja-Lena Deckner; Karolinska Institutet; Karolinska Institutet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; immunohistochemistry; in situ hybridization; rat; olfactory bulb; olfactory epithelium; axotomy; regeneration; apoptosis; BBB; VEGF; blood vessels; trophic factor; BDNF; trkB; tenascin;

    Abstract : The olfactory system has a striking capacity for neuronal plasticity throughout life and the olfactory epithelium is able to generate both neuronal and non-neuronal cells in the normal adult animal as well as after experimental injury. In contrast to primary sensory neurons, olfactory axons are able to cross the border between the PNS and CNS in the olfactory bulb after transection in the adult animal. READ MORE
