We characterized whether CD45EN TU cells contained effector-like CD8POS T cells using the markers Pdcd1 (encoding PD-1),60Gzmb (encoding granzyme-B),61 and Cd101 (encoding CD101),57 which are signatures for tumor Ag reactivity, cytotoxicity, and differentiation, respectively (Figure S5L). Here, PDCD1 is linked to neoplasm.
