CD274 and neoplasm: OC patients with residual tumor after surgery demonstrated elevated levels of PB-circulating PD-L1+ non-classical monocytes as well as tumor-infiltrated neutrophils, e-MDSC, γδTCM, and PD-L1+ γδT cells, with the corresponding other OC-associated compartments showing the same trends for these immune cell phenotypes (Supplementary Figure 18B).
