Eight cellular networks most frequently associated with altered gene expression in L. intracellularis infected pig ileum. As described by [31], the network function score ranks the network and takes into account the number of Network Eligible molecules in the network and its size, as well as the total number of Network Eligible molecules analysed and the total number of molecules in the Ingenuity Knowledge Base that could potentially be included in networks.
