Project description:Due to the common presence of a non-virion NV gene absent from other fish rhabdoviruses, NV-coding rhabdoviruses, such as the viral haemorrhagic septicemia (VHSV), were placed into a new Novirhabdovirus genus. Because conflicting results do exist on the importance of NV for VHSV trout pathogenicity and the NV function is still unclear, the effects of intraperitoneal injection of recombinant NV protein were studied by using home-designed immune-related microarrays from rainbow trout Oncorhynchus mykiss. The results were compared with parallel experiments using bacterial flagellins, a well know mammalian agonist of toll receptors (tlr5) with adjuvant activity recently described also in fish Four experimental groups were formed with four biological replicates each, 16 samples in total. First one was injected with NV recombinant protein in PBS, second one was a control group injected with PBS, the third group was injected with bacterial flagellins in PBS and the fourth group was injected with polihistidine peptide as a reference group because the recombinant proteins have a polihistidine tail. There is a technical replicate within each array.

Gene expression profiles after injection of zebrafish with NV (non virion) recombinant protein from Viral Hemorrhagic Septicemia Virus (VHSV)

Project description:NV is a viral protein only present in the genus Novirhabdovirus (fam Rhabdoviridae), its function is not well characterized yet. In this study we try to shed some light in the biological function of this viral protein in the zebrafish. We describe here transcripts induced after injection of adult zebrafish with NV recombinant protein of VHSV. Two days after infection, differentially expressed transcript levels from selected immune-related zebrafish genes were studied in zebrafish internal organs (pooled spleen and head kidney).
