The  IMMUPIGEN project (AGL2016-75432-R) aimed to decipher the molecular basis of immunity traits in pigs with the ultimate goal of including them in pig breeding programs to produce more robust and disease resistant animals. The METAPIGEN project (PID2020-112677RB-C21) pursues the research initiated with the IMMUPIGEN project and will focus on assessing the genetic relationships of the immunity and health-related traits with production performance, on identifying novel genes, transcripts, key regulators and biomarkers of immunocompetence (from transcriptomics and lipidomics data), and on the genetic and functional validation of polymorphisms identified in genes associated to health/immunity.
