OVA‐specific IFNγ‐producing CD8 T cells in spleen and tumor, as well as OVA‐tetramer positive CD8 T cells in the blood, were clearly detectable in the VSV‐GP group but only in about 30% of the mice (Figs. 2a and 2b, Supporting Information Fig. S4). The gene discussed is CD8A; the disease is neoplasm.
