Amoebic gill disease (AGD) is an emerging disease in North European Atlantic salmon (Salmo salar Linnaeus 1758) aquaculture caused by the amoeba Paramoeba perurans. The host immune response to AGD infection is still not well understood despite past attempts to investigate host-pathogen interactions. With the significant increase in our knowledge of cytokine(More)
In this study we show that four arginase isoforms (arg1a, arg1b, arg2a, arg2b) exist in rainbow trout (Oncorhynchus mykiss) and Atlantic salmon (Salmo salar). We have characterised these molecules in terms of a) sequence analysis, b) constitutive expression in different tissues, and modulated expression following c) stimulation of head kidney macrophages in(More)
Aeromonas salmonicida subsp. salmonicida is the etiologic agent of furunculosis, a frequent and significant disease of fisheries worldwide. The disease is largely controlled by commercial oil adjuvanted vaccines containing bacterins. However, the mechanisms leading to a protective immune response remain poorly understood. The type-three secretion system(More)
Aeromonas salmonicida subsp. salmonicida, the etiologic agent of furunculosis, is a major pathogen in aquaculture. Together with other pathogens, it is characterized by the presence of a type 3 secretion system (T3SS). The T3SS is the main virulence mechanism of A. salmonicida. It is used by the bacterium to secrete and translocate several toxins and(More)
ZBTB46 and DC-SCRIPT/ZNF366 are two zinc finger transcription factors that play important roles in regulating differentiation of dendritic cells in mammals. In this study, the ZBTB46 and DC-SCRIPT/ZNF366 homologues were identified in rainbow trout Oncorhynchus mykiss and their expression analysed in vivo and in vitro. As transcription factors, they are well(More)
