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

    Author : Viktoria Vedin; Anna Berghard; Urban Lendahl; Umeå universitet; []
    Keywords : 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. 2. Structure and Function of Odorant Binding Proteins and Chemosensory Proteins in Moths

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

    Abstract : 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.

  5. 3. Olfactory genomics of bark- and ambrosia beetles : Evolution and function of chemoreceptors

    Author : Twinkle Biswas; Feromongruppen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Curculionidae; functional characterisation; odorant receptors ORs ; gustatory receptors; ionotropic receptors; orthologues; paralogues; olfactory sensory neurons; OR-ligand interaction;

    Abstract : Insect behaviours, such as host and mate selection, are often mediated by chemical cues. The chemical cuesare detected by large and rapidly evolving families of chemoreceptors which include odorant receptors (ORs),gustatory receptors (GRs) and ionotropic receptors (IRs). READ MORE

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

    Author : Åsa Kolterud; Leif Carlsson; Stefan Thor; Umeå universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

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

    Author : Carolyn Marks; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : 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). READ MORE
