  1. 31. Hemolin expression during Cecropia development and its effect on malaria parasites

    Författare :Yohannes Assefaw-Redda; Ingrid Faya; Lage Cerenius; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Genetics; Genetik;

    Sammanfattning : Hemolin is a lepidopteran member of the immunoglobulin superfamily, initially isolated from the giant silkmoth Hyalophora cecropia. Hemolin is also induced by stimulation with microbial cell wall components and was recently shown to be strongly upregulated by baculovirus and double stranded RNA. LÄS MER

  3. 32. Hemolin, a versatile immune protein from the Cecropia moth

    Författare :Raul Bettencourt; Kenneth Söderhäll; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Genetics; genetik;

    Sammanfattning : Insects have become useful models for the study of innate immune mechanisms, due to their lack of antibodies and receptors involved in adaptive immune response. However, the molecules and mechanisms involved in primordial immune recognition are still poorly understood. LÄS MER

  4. 33. Site-specific recombination in P2-like coliphages

    Författare :Carlos Cardoso Palacios; Elisabeth Haggård-Ljungquist; Didier Mazel; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Genetics; Genetik; molekylärgenetik; Molecular Genetics;

    Sammanfattning : The scope of these studies has been to investigate the site-specific recombination systems of P2-like coliphages, both in an evolutionary perspective by a comparative analysis of related phages as well as in a functional perspective. Surveys of P2-like phages in Escherichia coli isolated from nature reveal the existence of seven discrete immunity classes and three integration sites, one of them previously unknown. LÄS MER

  5. 34. Functional characterization of interactions between the flavivirus NS5 protein and PDZ proteins of the mammalian host

    Författare :Karin Ellencrona; Magnus Johansson; Andrew Davidson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Tick-borne encephalitis virus TBEV ; West-Nile virus WNV ; Dengue virus DENV ; flavivirus; PDZ domains; ZO-2; ZO-1; RIMS2; Scribble; Interferon; JAK-STAT signaling; PDZ array; virus-host protein interaction; Genetics; Genetik; molekylärgenetik; Molecular Genetics;

    Sammanfattning : Flaviviruses are found all over the world and affect and infect millions of people every year. Flavivirus infection can lead to severe clinical outcomes resulting in neuronal damages e.g. Tick-borne encephalitis virus (TBEV), or severe hemorrhagic fevers e. LÄS MER

  7. 35. Structure-Function Studies of Bacteriophage P2 Integrase and Cox protein

    Författare :Jesper Eriksson; Elisabeth Haggård; Karin Hammer; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Bacteriophage P2; site-specific recombination; integrase; transcriptional switch; Genetics; Genetik;

    Sammanfattning : Probably no group of organisms has been as important as bacteriophages when it comes to the understanding of fundamental biological processes like transcriptional control, DNA replication, site-specific recombination, e.t.c.The work presented in this thesis is a contribution towards the complete understanding of these organisms.
