  1. 1. Drosophila Sensory Neuroethology

    Detta är en avhandling från Lund University, Faculty of Science, Department of Biology

    Författare :Suzan Mansourian; [2018-05]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Drosophila melanogaster; Vinegar Fly; olfactory system; hygrosensation; receptor; ancestral habitat;

    Sammanfattning : Animals, like humans, need to perceive their surroundings via their senses in order to make sensible behavioral decisions, reproduce successfully, and survive. Animals are equipped with audition, vision, thermosensation, hygrosensation, mechanosensation, magnetoception, gustation, and olfaction, which detects physical and chemical changes in their habitats.

  2. 2. Peptidoglycan recognition proteins in Drosophila melanogaster

    Detta är en avhandling från Umeå : Umeå centrum för molekylär patogenes (UCMP) (Medicinska fakulteten)

    Författare :Thomas Werner; Dan Hultmark; Bruno Lemaitre; [2004]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; Drosophila; PGRP; peptidoglycan; pattern recognition; imd; Relish; isoform; RNAi; mbn-2; Molekylärbiologi; NATURAL SCIENCES Biology Cell and molecular biology Molecular biology; NATURVETENSKAP Biologi Cell- och molekylärbiologi Molekylärbiologi; molekylärbiologi; Molecular Biology;

    Sammanfattning : The fruit fly Drosophila melanogaster is an excellent model organism to study the innate immune response, because insects and mammals share conserved features regarding the recognition and destruction of microorganisms and Drosophila is easily accessible to genetic manipulation. In my present study, I identified a new family of pattern recognition molecules for bacterial peptidoglycan in Drosophila, the Peptidoglycan Recognition Proteins (PGRP). LÄS MER

    Sammanfattning : In general the work behind this thesis has revolved around the interesting pattern recognition gene family PGRPs (peptidoglycan recognition proteins). In particular the transmembrane PGRP-LC and to investigate its multifaceted role in the immune response of the fruit fly. LÄS MER

  4. 4. Mitochondrial Iron Metabolism Study of mitoferrin in Drosophila melanogaster

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Christoph Metzendorf; Maria Lind Karlberg; Kenneth Söderhäll; Martina Muckenthaler; [2010]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; iron; Drosophila; mitochondria; mitoferrin; ferritin; spermatogenesis; cell cycle; DFO; MRS12; NATURAL SCIENCES Biology Cell and molecular biology; NATURVETENSKAP Biologi Cell- och molekylärbiologi; Biology with specialization in Comparative Physiology; Biologi med inriktning mot jämförande fysiologi;

    Sammanfattning : Iron has a dualistic character. On the one hand it is essential for the life of most organisms, on the other hand it is involved in the generation of reactive oxygen species that are implicated in diseases and aging. LÄS MER

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

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Karin Johansson; Uppsala universitet.; [2005]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cell biology; Drosophila; innate immunity; bacteria; host - pathogen interaction; Cellbiologi; NATURAL SCIENCES Biology Cell and molecular biology Cell biology; NATURVETENSKAP Biologi Cell- och molekylärbiologi Cellbiologi;

    Sammanfattning : 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.
