Outline of Final Research Achievements

We had previously produced pigs with high immune competence by selection of phagocytic capacity, complement-activating capacity by alternative pathway, and antibody response after vaccination with swine erysipelas. In this study, we performed microarray analysis by using macrophages from pigs of high immune competence or control, and identified 44 immune genes showed more than three times difference in the changes of gene expression after ligand stimulation between pig groups. Furthermore, we searched polymorphisms which had biased distribution between the pig groups in 5 kb of promoter region of these genes, and estimated haplotypes consisting of these polymorphisms. As a result, we elucidated specific types of promoter which were considered to be significantly increased in frequency by selection of immune competence in the genes encoding RNASEL, SAMHD1, STAT3, TRIM21, and TMEM150C, respectively.
