  1. 1. Peptidoglycan Recognition Proteins Major Regulators of Drosophila Immunity

    University dissertation from Stockholm : Institutionen för genetik, mikrobiologi och toxikologi

    Author : Peter Mellroth; Stockholms universitet.; [2005]
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Innate immunity; peptidoglycan recognition protein; PGRP; Toll; Imd; Drosophila immunity; VETERINARY MEDICINE Microbiology and immunology; VETERINÄRMEDICIN Mikrobiologi och immunologi;

    Abstract : All eukaryotic organisms have an innate immune system characterized by germ-line encoded receptors and effector molecules, which mediate detection and clearance of microbes such as bacteria, fungi, and parasites. VertebrateDrosophila as a genetically tractable organism with aThis thesis concerns the peptidoglycan recognition protein (PGRP) gene family in the fruit fly. READ MORE

  2. 2. Peptidoglycan recognition proteins in Drosophila melanogaster

    University dissertation from Umeå : Umeå centrum för molekylär patogenes (UCMP) (Medicinska fakulteten)

    Author : Thomas Werner; Umeå universitet.; [2004]
    Keywords : 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;

    Abstract : 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). READ MORE

  3. 3. Innate Immune Proteins in a Crustacean Pacifastacus leniusculus

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Chenglin Wu; Uppsala universitet.; [2011]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; 2-DE; hematopoiesis; marker protein; melaniztion inhibiting protein; proPO-system; pattern recognition protein; PGN; ficolin-like protein; NATURAL SCIENCES Biology Cell and molecular biology Immunology; NATURVETENSKAP Biologi Cell- och molekylärbiologi Immunologi; Biology with specialization in Comparative Physiology; Biologi med inriktning mot jämförande fysiologi;

    Abstract : Hemocytes (blood cells) are important in the immune defense against pathogens in invertebrates. In crusteacean, the hemocytes and plasma components mount a strong innate immune response against different pathogens including bacteria and virus. READ MORE

  4. 4. Vesicle-mediated and free soluble delivery of bacterial effector proteins by oral and systemic pathogens

    University dissertation from Umeå : Umeå Universitet

    Author : Bernard Thay; Umeå universitet.; [2013]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Periodontitis; Aggregatibacter actinomycetemcomitans; Staphylococcus aureus; membrane vesicles; vesicle-host cell interaction; protein delivery; molekylärbiologi; Molecular Biology;

    Abstract : Periodontitis, the primary cause of tooth-loss worldwide, is a bacterially induced chronic inflammatory disease of the periodontium. It is associated with systemic conditions such as cardiovascular disease (CVD). However, pathogenic mechanisms of periodontitis-associated bacteria that may contribute to the CVD association are unclear. READ MORE

  5. 5. Identification and characterisation of five innate immune genes in the cabbage looper Trichoplusia ni

    University dissertation from Stockholm : Department of Microbiology, Stockholm University

    Author : Annika Lundström; Stockholms universitet.; [2001]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; mikrobiologi; Microbiology;

    Abstract : When insects are infected with bacteria, they respond by producing a range of different antibacterial peptides and by activating protease cascades leading to coagulation and melanisation. Cellular defence mechanisms are also involved in killing of microorganisms through phagocytosis and encapsulation. READ MORE
