After coculture with the cells from D8 TDLN, the tumor peptide AH1 was able to stimulate a considerable amount of interferon-γ+ (IFNγ+) tumor-specific CD8+ T cells, while the irrelevant control antigen peptide ovalbumin (OVA) showed no effect of stimulation (Fig. 3G). Here, CD8A is linked to neoplasm.
