    FcRn is a key player in several immunological and non-immunological processes, as it mediates maternal-fetal transfer of IgG, regulates the serum persistence of IgG and albumin, and transports both ligands between different ...

    TCTP has been implicated in a plethora of important cellular processes related to cell growth, cell cycle progression, malignant transformation and inhibition of apoptosis. In addition to these intracellular functions, ...

    European eel migrate from freshwater or coastal habitats throughout Europe to their spawning grounds in the Sargasso Sea. However, their route (∼ 6000 km) and orientation mechanisms are unknown. Several attempts have been ...
  • Mysterud, Atle; Easterday, William Ryan; Qviller, Lars; Viljugrein, Hildegunn; Ytrehus, Bjørnar (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2013)
    Background. Understanding the variation in prevalence of Borrelia burgdorferi sensu lato (Lyme Borreliosis Spirochaetes, LBS) and Anaplasma phagocytophilum (causing tick-borne fever in ruminants and human granulocytic ...
  • Gautestad, Arild O.; Mysterud, Atle (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2013)
    Background. The Lévy flight foraging hypothesis predicts a transition from scale-free Lévy walk (LW) to scale-specific Brownian motion (BM) as an animal moves from resource-poor towards resource-rich environment. However, ...
  • Harbeck, Michaela; Seifert, Lisa; Hänsch, Stephanie; Wagner, David; Birdsell, Dawn; Parise, Katy L.; Wiechmann, Ingrid; Grupe, Gisela; Thomas, Astrid; Keim, Paul; Zöller, Lothar; Bramanti, Barbara; Riehm, Julia; Scholz, Holger C. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2013)
    Yersinia pestis, the etiologic agent of the disease plague, has been implicated in three historical pandemics. These include the third pandemic of the 19th and 20th centuries, during which plague was spread around the ...
