Interestingly, the kinetic and extent of NKG2A expression was found to differ depending on the compartment; faster up-regulation was observed in the tumor, where already 24 h post VSV-GP-HPV boost 90% of E7-specific CD8 T cells expressed higher levels of NKG2A and maintained it until at least day 14 post boost. This evidence concerns the gene CD8A and neoplasm.
