The majority of the granulocytes were CD15+CD16+CD14±, corresponding with granulocyte-MDSCs (G-MDSC) [27,28] or antigen-presenting tumour associated neutrophils [29], marked by their HLA-DR expression (metacluster 4), although we also observed the co-expression of PD-L1. The gene discussed is CD14; the disease is neoplasm.
