Next, we detected the expression of PD‐L1 in NF2‐associated meningiomas and found that positive expression of PD‐L1 was observed in 38.46% (5/13) of NF2‐associated meningiomas according to IHC and 53.85% (7/13) of NF2‐associated meningiomas according to Western blotting. The gene discussed is CD274; the disease is meningioma.
