Coexpression with high level of both PD-L1 and B7-H4 expression was limited in the IHC cohort. Distributions of PD-L1/B7-H4 subgroups in gliomas (A). Representative cases of PD-L1/B7-H4 subgroups were shown with the same area for per sample: case 1, High-PD-L1 subgroup; case 2, high-B7-H4 subgroup; case 3, double-Low subgroup; case 4, double-High subgroup (B). Magnification, ×40 objective; Bar, 20 um. PD-L1, programmed death ligand 1.
