Thus, future studies should investigate the correlations among Th2 scores, the PD-L1/PD-1 axis, and the expression profiles based on the 14 candidate genes, especially SLC11A1, TNFRSF1B, and LTBR, as well as how these parameters can be used to effectively predict prognoses of GBM patients. The gene discussed is TNFRSF1B; the disease is glioblastoma.
