Technical Summary
Porcine Reproductive and Respiratory Syndrome which is caused by a viral pathogen (PRRSv) is an endemic disease with major effects on pig production. We will investigate the host's response to PRRSv infection in cultured alveolar macrophages and whole animals. We will identify genes involved in the host's response to PRRSv infection by expression profiling using microarray technology. We will identify loci determining the host's response to PRRSv through a genome scan exploiting linkage disequilibrium to single nucleotide polymorphisms. This project represents a paradigm for exploiting genomic and post-genomic knowledge and technology to identify the genes involved in the host's response to infectious disease in pigs. The knowledge acquired from this project will underpin improvements in healthier animal production. (Joint with grants 104/EGA16309 and 8/EGA16308).

Sector | Private |
PI Contribution | This collaborative project was led from the Roslin Institute, which was integrated into the University of Edinburgh as The Roslin Institute towards the end of the project. In addition to overall leadership of the project staff based at Roslin undertook the expression profiling experiments and analysis of the microarray results, the in vitro challenges of macrophages with PRRSV, and the genetic analysis of the field data. |
Collaborator Contribution | The Veterinary Laboratory Agency acting as a sub-contractor to the Cambridge partner undertook the animal challenge experiments - a PRRSV challenge of growing pigs and a PSSRV challenge of pregnant gilts. The Wellcome Trust Sanger Institute undertook a programme of SNP (single nucleotide polymorphism) discovery. The University of Cambridge performed SNP discovery experiments on physiological candidate genes. Sygen/PIC provided animals for the challenge experiments and as a source of cells for the in vitro experiments. Sygen/PIC also provided DNA samples for the SNP discovery experiments |
Impact | The SNPs discovered within this project together with SNPs discovered by collaborators in Denmark and Norway were used to design the first genomewide SNP panel for genetic studies in pigs (Gregersen et al., 2008). The 7K SNP chip was developed in collaboration with Illumina Inc. In addition to being used in this PRRS project (ca. 1000 samples) the chip has also been used by Roslin Institute in another BBSRC-funded project (ca. 1000 samples) and an EU-funded project (ca. 1000 samples). At least 20,000 samples have been genotyped with this chip in a range of research projects across Europe. SNPs discovered in this BBSRC PRRS project have also been incorporated into the design of the second generation pig (60K) SNP chip in collaboration with research groups in Europe and the USA and Illumina Inc. This 60K SNP chip is currently being manufactured. Orders from around the globe have been placed for sufficient chips to genotype > 40,000 samples. The Expressed Sequence Tags (ESTs) generated within this project were included in the sequence data from which the second generation international pig long oligonucleotide set for microarray fabrication was designed (Fahrenkrug et al., 2007). The oligonucleotides were synthesised and marketed by Invitrogen. |
