  • CpGs Induce Differentiation of Atlantic Salmon Mononuclear Phagocytes Into Cells With Dendritic Morphology and a Proinflammatory Transcriptional Profile but an Exhausted Allostimulatory Activity 

    Iliev, Dimitar Borisov; Lagos, Leidy; Thim, Hanna Leena; Jørgensen, Sven Martin; Krasnov, Aleksei; Jørgensen, Jorunn B (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-03-13)
    Due to their ability to present foreign antigens and prime naïve T cells, macrophages, and dendritic cells (DCs) are referred to as professional antigen-presenting cells (APCs). Although activated macrophages may function as APCs, these cells are particularly effective at directly engaging pathogens through phagocytosis, and production of antimicrobial compounds. On the other hand, DCs possess superb ...
  • Rethinking capitalist transformation of fisheries in South Africa and India 

    Menon, Ajit; Sowman, Merle; Bavinck, Jan Maarten (Journal article; Tidsskriftartikkel; Peer reviewed, 2018)
    The industrialization of fisheries and the growth of a capitalist sector within fisheries have received considerable scholarly attention. For the most part, scholars have emphasized how capitalism has led to privatization of the commons, forced small-scale resource users into wage labor, and marginalized the sector. This analysis does not, however, explain the continued presence of such a vibrant ...
