After using the TISIDB database, 6 immunoinhibitors (CD160, CD244, CD96, HAVCR2, IL10, and PVRL2) (Figure 6(a)) and 11 immunostimulators (C10orf54, CD276, CD48, CD86, PVR, TMIGD2, TNFRSF14, TNFRSF8, TNFSF13, TNFSF13B, and TNFSF14) (Figure 6(b)) were identified significantly associated with EFNB1 in GBM. This evidence concerns the gene HAVCR2 and glioblastoma.
