BACKGROUND Once a list of differentially expressed genes has been identified from a microarray experiment, a subsequent post-analysis task is required in order to find the main biological processes associated to the experimental system. This paper describes two pathways analysis tools, ArrayUnlock and Ingenuity Pathways Analysis (IPA) to deal with the(More)
The innate immune system has the basic function of identifying and eradicating microbial invaders and alerting the adaptative immune system to their presence. In this study, the porcine intestinal innate immune response was evaluated by analysing the expression of TLRs, cytokines and chemokines in two porcine epithelial cell lines from different regions:(More)
Salmonella enterica serovar Typhimurium causes enteric disease and compromises food safety. In pigs, the molecular response of the intestine to S. typhimurium has been traditionally characterized by in vitro models that do not reflect the actual immunological competence of the intestinal mucosa. In this work, we performed an oral S. typhimurium infection(More)
In this paper, we present the protein map corresponding to the porcine peripheral blood mononuclear cells (PBMC) to better understand the role of these cells in the pig immune system. To conform the map, the proteins were separated by 2-DE using a 5-8 range pH gradient in IEF and approximately 800 spots were detected. Due to the high level of indeterminate(More)
Alveolar macrophages (AM) are the primary phagocytes of the innate immune systems, constituting a link between innate and adaptive immunity. With the aim of studying the porcine AM biology and the dynamics of pig-pathogen cell interactions, we have obtained a reference 2-DE map of the porcine AM proteins. The proteins were separated by 2-DE using a 5-8(More)
BACKGROUND The aim of this paper was to describe and compare the methods used and the results obtained by the participants in a joint EADGENE (European Animal Disease Genomic Network of Excellence) and SABRE (Cutting Edge Genomics for Sustainable Animal Breeding) workshop focusing on post analysis of microarray data. The participating groups were provided(More)
Porcine circovirus type 2 (PCV2) has been identified as the essential causal agent of postweaning multisystemic wasting syndrome. However, little is known regarding the mechanism(s) underlying the pathogenesis of PCV2-induced disease and the interaction of the virus with the host immune system. Here, we present a proteomics study on inguinal lymph nodes of(More)
