  2. 1. Interaction Between Drosophila melanogaster mbn-2 Cells and Bacteria

    Author : Karin Johansson; Kenneth Söderhäll; Lage Cerenius; Martin Bilej; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cell biology; Drosophila; innate immunity; bacteria; host - pathogen interaction; Cellbiologi; Cell biology; Cellbiologi;

    Abstract : Innate immunity relies on a repertoire of germline-encoded non-rearranging pattern recognition receptors that bind to invariant microbial surface molecules. This event initiates a number of signal transduction cascades that lead to humoral and cellular defense responses like synthesis of antimicrobial peptides, phagocytosis and coagulation – mechanisms that efficiently fight infectious microorganisms and have been evolutionary conserved to exist in parallel with the antibody-based adaptive immunity found in vertebrates.

  4. 2. The RNA exosome and the maintenance of genome integrity

    Author : Judit Domingo Prim; Neus Visa; Andrés Aguilera; Stockholms universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; EXOSC10; RRP6; DNA damage; diRNA; DDRNA; DNA end resection; homologous recombination; molekylär biovetenskap; Molecular Bioscience;

    Abstract : The RNA exosome is a ribonucleolytic complex that acts on different RNA substrates and plays important roles in RNA metabolism. In recent years, the synthesis and the processing of RNA have been directly linked to the integrity of the genome. READ MORE

  5. 3. Revisiting cell specification and differentiation in the Drosophila airways, an insect organ homologous to our lung and blood vessels

    Author : Ryo Matsuda; Christos Samakovlis; Payre Francois; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; cell differentiation; airways; Drosophila; cell signaling; transcription factors; utvecklingsbiologi; Developmental Biology;

    Abstract : Oxygen is essential for life. Aquatic ancestral animal species are thought to have independently terrestrialized and invented distinct strategies for efficient oxygen supply. The respiratory system of vertebrates like us is composed of lungs connected to the vasculature while insects have a single system delivering air directly to internal tissues. READ MORE

  6. 4. 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

  7. 5. Fatty Acyl Reductases and Fatty Acyl Desaturases. Deciphering the biosynthesis of species-specific moth female sex pheromones from common fatty acids

    Author : Åsa Hagström; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Moth; pheromone; insect; evolution; fatty acyl desaturase; fatty acyl reductase; endoplasmic reticulum; fatty acid biosynthesis; GFP; heterologous expression; phylogeny; cell factory; lepidoptera;

    Abstract : Moths (Lepidoptera) are dependent on female produced pheromones, chemical signals, for attracting a mate. Pheromones are most commonly made up by saturated and/or unsaturated fatty acid derived alcohols, acetates, and/or aldehydes that are produced by a set of enzymes in the female pheromone gland.
