Summary:碩士 === 國立彰化師範大學 === 生物技術研究所 === 103 === The n-3 PUFA is important for human health, but can not be synthesised these essential fatty acid in human body. It’s well known that n-3 fatty acids in dietary fish oil are reported to have anti-inflammatory and injury effects in humans, but the biochemical basis and the molecular mechanism for these beneficial health effects is still not well understood. In our results, Streptococcus iniae can alter the host immune response through toll-like receptors (TLRs), and then promote the downstream target, Myd88 to induce the expression of inflammatory related genes, and cause high mortality. By comparison, the surrvival rate of transgene Δ5 and Δ6 desaturase zebrafish is higher than wild type 1.33 folds. By the way, we try to use PD1 as a novel inhibitor for NNV replication. The survival rate of PD1 treated GF1 was similar to the control. ROS level significantly when comparing to the control cells. The PD1 treated cells also decreased the cytopathic effect(CPE) at 42 hpi, but the results is not so clear. We also machinery, and to understand the role of ROS during NNV infection.
