CD8A and neoplasm: When B16 tumor cells constitutively expressing ovalbumin were used, tetramer analysis of T-cell receptors showed that ACE 10/10 mice have more circulating tumor-specific CD8+ T cells with specificity for the ovalbumin epitope SIINFEKL and the B16 TRP-2 epitope (SVYDFFVWL) than WT mice.
