To address this, we performed CyTOF profiling of tumor-infiltrating immune cell populations (Fig. 3A–I, Figure S3A and B), including lymphocytes (CD45+CD66b−) (Fig. 3B), granulocytes (CD45lowCD66b+) (Fig. 3C), CD3+ T cells (CD45+CD3+) (Fig. 3D), NK cells (CD45+CD56+) (Fig. 3E), gamma delta (γδ) T cells (CD4−CD8−TCRγδ+) (Fig. 3F), B cells (CD19+CD3−) (Fig. 3G), monocytes/macrophages (CD11c+HLA-DR+) (Fig. 3H), and dendritic cells (HLA-DR+) (Fig. 3I). Here, CD19 is linked to neoplasm.
