    Abstract:
    Hydrolyzed fish proteins (H-pro) contain high concentrations of free amino acids and low molecular peptides that potentially may benefit fish health. The following study aimed to test whether the water-soluble phase of H-pro could attenuate lipopolysaccharide (LPS) provoked inflammation in liver cells and head kidney cells isolated from Atlantic salmon. Cells were grown as mono cultures or co cultures to assess possible crosstalk between immune cells and metabolic cells during treatments. Cells were added media with or without H-pro for 2 days before LPS exposure and harvested 24 h post LPS exposure. Respective cells without H-pro and LPS were used as controls. H-pro alone could affect expression of proteins directly as H-pro increased catalase protein expression in head kidney- and liver cells, regardless of culturing methods and LPS treatment. Leukotriene B4 (LTB4) production was also increased by H-pro in head kidney cells co cultured with liver cells. H-pro increased LPS induced interleukin 1β (IL-1β) transcription in liver cells co cultured with head kidney cells. All cultures of head kidney cells showed a significant increase in IL-1β transcription when treated with H-pro + LPS. H-pro decreased caspase-3 transcription in liver cells cultured co cultured with head kidney cells. Peroxisome proliferator activated receptor α (PPAR α) was upregulated, regardless of treatment, in liver cells co cultured with head kidney cells clearly showing that culturing method alone affected gene transcription. H-pro alone and together with LPS as an inflammation inducer, affect both antioxidant and inflammatory responses.
