Gene interaction network representing the interferon-induced antiviral effectors differentially expressed in both mediastinal lymph node and blood datasets. Small red circles indicate up-regulated genes. The Metacore software (GeneGO Inc.) was used to create the network. The six common genes to mediastinal lymph node and blood datasets, indicated by tricolor circles, were the starting nodes. Blue circles represent genes added manually. Red, green, and grey arrows indicate activation, inhibition and unspecified interactions between connected genes, respectively. (A color version of this figure is available at: www.vetres.org.)
