A comprehensive transcriptional body map of Atlantic salmon unveils the vital role of the intestine in the immune system and highlights functional specialization within its compartments
Kortner, Trond M.; Afanasyev, Sergey; Koppang, Erling Olaf; Bjørgen, Håvard; Krogdahl, Åshild; Krasnov, Aleksei (Peer reviewed; Journal article, 2024)The intestine is a barrier organ that plays an important role in the immune system of Atlantic salmon. The immune functions are distributed among the diffuse gut lymphoid tissue containing diverse immune cells, and other ... -
Consequences of Haemorrhagic Smolt Syndrome (HSS) for the Immune Status of Atlantic salmon (Salmo salar L.) (Case Study)
Krasnov, Aleksei; Sommerset, Ingunn; Søfteland, Tina; Afanasyev, Sergey; Boysen, Preben; Lund, Hege (Peer reviewed; Journal article, 2020)Haemorrhagic smolt syndrome (HSS) is a disorder of unknown aetiology causing losses in the fresh water phase of Atlantic salmon farming. Normally, the mortality is limited and symptoms disappear upon seawater exposure. In ... -
Development of Atlantic Salmon (Salmo salar L.) Under Hypoxic Conditions Induced Sustained Changes in Expression of Immune Genes and Reduced Resistance to Moritella viscosa
Krasnov, Aleksei; Burgerhout, Erik; Johnsen, Hanne; Tveiten, Helge; Bakke, Anne Flore; Lund, Hege; Afanasyev, Sergey; Rebl, Alexander; Johansen, Lill-Heidi (Peer reviewed; Journal article, 2021)Atlantic salmon is characterized with high sensitivity to low dissolved oxygen (DO) levels. Hypoxia can affect diverse biological processes with consequences that can be manifested immediately or with delay. Effects of ... -
Differentiation and traffic of IgM+ B cells between focal dark spots in skeletal muscle of Atlantic salmon, lymphoid and adipose tissues
Jiménez-Guerrero, Raúl.; Karlsen, Christian; Boudinot, Pierre; Afanasyev, Sergey; Mørkøre, Turid; Krasnov, Aleksei (Journal article; Peer reviewed, 2023) -
Effect of two constant light regimens on antibody profiles and immune gene expression in Atlantic salmon following vaccination and experimental challenge with salmonid alphavirus
Bakke, Anne Flore; Rebl, Alexander; Frost, Petter; Afanasyev, Sergey; Røyset, Kristoffer Alnes; Søfteland, Tina; Lund, Hege; Boysen, Preben; Krasnov, Aleksei (Peer reviewed; Journal article, 2021)Before seawater transfer, farmed Atlantic salmon are subjected to treatments that may affect the immune system and susceptibility to pathogens. E.g., exposure to constant light (CL) stimulates smoltification, which prepares ... -
Endocrine and Transcriptome Changes Associated with Testicular Growth and Differentiation in Atlantic Salmon (Salmo salar L.)
Skjold, Vetle; Afanasyev, Sergey; Burgerhout, Erik; Sveen, Lene; Rørvik, Kjell-Arne; Mota, Vasco Filipe Cardoso Neves; Dessen, Jens-Erik; Krasnov, Aleksei (Peer reviewed; Journal article, 2024) -
Evaluation of Immune Status in Two Cohorts of Atlantic Salmon Raised in Different Aquaculture Systems (Case Study)
Lund, Hege; Bakken, Anne Marie; Boysen, Preben; Afanasyev, Sergey; Rebl, Alexander; Manji, Farah; Ritchie, Gordon; Krasnov, Aleksei (Peer reviewed; Journal article, 2022) -
IgM+ and IgT+ B Cell Traffic to the Heart during SAV Infection in Atlantic Salmon
Bakke, Anne Flore; Bjørgen, Håvard; Koppang, Erling Olaf; Frost, Petter; Afanasyev, Sergey; Boysen, Preben; Krasnov, Aleksei; Lund, Hege (Peer reviewed; Journal article, 2020)B cells of teleost fish differentiate in the head kidney, and spleen, and either remain in the lymphatic organs or move to the blood and peripheral tissues. There is limited knowledge about piscine B cell traffic to sites ...
