In order to corroborate previous findings that showed CD96-mediated immune suppression in the MC-38 tumor model, we first confirmed via flow cytometry the expressions of CD96 on both tumor infiltrating T cells and NK cells (Figure S1A), as well as the expression of the CD96 main ligand, CD155, on non-leukocytic cells (Figure S1B). The gene discussed is PVR; the disease is neoplasm.
