Interaction network. Proteins from M. musculus homologous to those identified in F. catus as differentially abundant on day 21 after inoculation with T. gondii. Each node represents a protein. The larger triangle-shaped nodes denote the proteins identified as having increased abundance, and the inverted triangle-shaped proteins represent those that were identified as having reduced abundance in comparison with the proteins identified on day 5. The proteins within the red square also had a significant difference of expression on day 21 after inoculation compared to proteins identified on day 0. The node degree is represented by the edge of the nodes, where wider edges correspond to greater node degrees. The betweenness value is represented on the blue tone scale. Clusters are numbered and separated into grids. One or two biological processes were assigned to each cluster. The p-value of the hypergeometric test with Benjamini & Hochberg false discovery rate (FDR) correction is shown for each process
