CD4 and glioblastoma: Otherwise, in GBM, GPX7 only positively correlated with common lymphoid progenitors (ρ = 0.485; p = 1.89e−09), CD8+ (ρ = 0.290; p = 0.0005), myeloid-derived suppressor cells (ρ = 0.379; p = 4.93e−06) and CAFs (ρ = 0.220; p = 0.009), while it was negatively correlated with B cells (ρ = − 0.322; p = 0.0001), eosinophils (ρ = − 0.413; p = 5.13e−07), monocytes (ρ = − 0.348; p = 3.03e−05), CD4 + T cells (ρ = − 0.354; p = 2.08e−05), NK cells (ρ = − 0.393; p = 2.02e−06) and NKT cells (ρ = − 0.331; p = 0.0006) (Fig. 11 and Supplementary Table S7).
