PD-L1 and PD-L2 expression in pulmonary squamous cell carcinoma is associated with an increased number of CD8(+) tumor infiltrating lymphocytess and increased MET expression.

Data indicate that pulmonary pleomorphic carcinoma (PC) very frequently express CD274 antigen (PD-L1) and CD273 antigen (PD-L2).

PD-L2 copy number gains were not related to PD-L2 augmentation in non-small cell lung cancer.

High PD-L2 expression may be a target of immunotherapy in patients with PD-L1-negative Non-small Cell lung cancer.

PD-L2-positive lung adenocarcinomas are less radiologically malignant and invasive than their PD-L1-positive counterparts

Low PD-L2 expression is associated with lung Adenocarcinoma.
