| Outline of Final Research Achievements |
We analyzed RNA sequence data on several glioma tissues. We also conducted expression profiling of immuno-related gene using data of 158 glioblastoma multiforme (GBM) patients with clinical information available at The Cancer Genome Atlas. The results revealed that Th1HighTh2Low and Th1LowTh2Low statuses indicated better prognosis than Th1HighTh2High, and were evaluated based on the down regulation of PD-L1, PD-L2, and PD-1. These results suggest that low Th2 balance and low activity of the PD-L1/PD-1 axis predict good prognosis in GBM. Furthermore, CD276 expression and the gene signature composed of GATA3 and LGALS3 are effective for prognosis in GBM and will help us understanding target pathways for immunotherapy in GBM.
