Project description:We found that fuse ΔLMP1 to MAVS could strengthen MAVS mediated inhibition of PRRSV replication in MARC-145 cells. To better understand the biological function of the fusion protein ΔLMP1-MAVS, overall gene expression of MARC-145 cells transfected with ΔLMP1-MAVS or MAVS was evaluated by mRNA-seq. The result showed that ΔLMP1-MAVS upregulated a number of genes associated with innate immune responses to viral infection, including plenty of interferon-stimulated genes. This study provides reference date to research the working mechanism of ΔLMP1-MAVS.
Project description:Perkinsus marinus is an intracellular parasitic protozoan that is responsible for serious disease epizootics in marine bivalve molluscs worldwide and along with P. olseni belongs to the OIE list of notified diseases. Despite all available information on P. marinus genomics, more baseline data is required at the proteomic level for a better understanding of P. marinus biological processes, including virulence mechanisms. In the present study, we have established in vitro clonal cultures of P. marinus from infected gills and mantle tissues of C. rhizophorae to evaluate the parasite cellular proteomic profile. A high throughput label-free shotgun HDMS approach using nanoUPLC-MS was used. Our intention was to provide the first comprehensive proteome profile of P. marinus that might serve as a valuable resource for future investigations involving comparative analyses of P. marinus from different regions, as well as comparisons of different species of Perkinsus.
