In the PPI network of the Tuberculosis pathway, we found 21 mRNAs marked by the blue oval (Figure 5B), and we also obtained an important module with the following ranking order: TNF, IL6, IL1B, NFKB1, TRAF6, IL1A, IRAK2, ITGAM, RIPK2, JAK1 (Table 3). The gene discussed is RIPK2; the disease is tuberculosis.
