  1. 1. Stopover Ecology of Mallards : Where, when and how to do what?

    Författare :Daniel Bengtsson; Jonas Waldenström; W. Michael Eichholtz; Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Age characters; body condition; departure decision; effects of influenza A virus; habitat selection; mallard; movement; Ottenby Bird Observatory; stopover ecology; weather; wild birds; Ecology; Ekologi;

    Sammanfattning : The mallard (Anas platyrhynchos) is the most numerous and widespread duck in the northern hemisphere and a model species in ecology and harvest management. Migration is a crucial life stage for many birds and understanding the drivers of migration has important implications for conservation biology and assessment of animal population responses to global changes.

  3. 2. Neurotropic influenza A virus infection in the mouse brain : targeting, persistence and functional effects

    Författare :Fredrik Aronsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Influenza A virus; nervous system;

    Sammanfattning : Viral infections of the central nervous system have been associated with sensory, motor and behavioral disturbances both in humans and in animals. An example of this is influenza A virus infection that causes acute respiratory diseases, which occasionally are followed by complications from the central nervous system. LÄS MER

  4. 3. Roles of mammalian Scribble in polarity signaling, virus offense and cell-fate determination

    Författare :Michael Wigerius; Magnus Johansson; Lawrence Banks; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cell polarity; scribble; tbev; RhoGTPase; jak-stat; mapk; neurite outgrowth; influenza a virus; Biochemistry; Biokemi; biokemi; Biochemistry;

    Sammanfattning : Mammalian Scribble is a target for proteins encoded by human papilloma virus, retro- and flaviviruses. Tick-borne encephalitis virus (TBEV) is a flavivirus that have evolved distinct strategies to escape antiviral responses. LÄS MER

  5. 4. Influenza A virus in natural and artificial environments

    Författare :John Wahlgren; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Influenza is caused by influenza A virus, a single stranded RNA virus of the orthomyxoviridae family. In humans, it causes yearly outbreaks with high morbidity and excess fatality rates as a direct effect. Placed in its ecological niche however, in dabbling ducks, avian influenza virus (AIV) induce quite mild disease. LÄS MER

  7. 5. Effects of influenza A virus infections and interferon-gamma on synapse formation and function in hippocampal neurons in culture

    Författare :Johan Brask; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Influenza A virus; hippocampal neurons; interferon-gamma; electrophysiology; synapses.;

    Sammanfattning : The central nervous system (CNS) can be the target for several infections that include those with RNA viruses. The parenchyma of the CNS is considered an immuneprivileged site since it is protected behind the blood-brain barrier, expresses no or only low levels of major histocompatibility complex (MHC) molecules and contains a paucity of antigenpresenting cells that prime an immune response.
