Heatmap of probesets showing individual Log2 fold gene expression level with the different treatments and the pig groups (unvaccinated control, CNTRL; Low Responder, LR; High Responder, HR). Pig identification is shown below heatmap: pig number 24, 34 and 5 for control pigs; pig number 26, 59 and 61 for LR pigs; pig number 16, 21, 38 for HR pigs. Rows, representing gene symbols for each probeset except for LOC396781, were ordered by hierarchical clustering and columns were displayed ordered by treatment (mock, in grey; PHA, in orange; vaccine, in blue). Log2 expression scale is shown. A red line box highlights heatmap of groups treated with vaccine.
