ACTIVE MOIETY

Comments:

The existence of overlapping CD8 and CD4 T-cell epitopes within certain tumor antigens provides an opportunity to test the hypothesis that relatively short peptides could be used to generate both CD8 and CD4 T cells against tumor. In this report, T-cell responses to a fragment of the tumor antigen NY-ESO-1 that contained an HLA-DP4-restricted helper T cell epitope as well as an HLA-A2-restricted cytotoxic T cell epitope were analyzed. One peptide, ESO:157170 (SLLMWITQCFLPVF) was recognized by both NY-ESO-1-reactive CD8 and CD4 T-cell clones. Both CD4 and CD8 T cells were efficiently generated from the peripheral blood of multiple melanoma patients after in vitro stimulations using ESO:157170. Dual-specific peptides containing both cytotoxic T-cell and helper T-cell epitopes may represent an attractive strategy of vaccine design aimed at generating tumor-reactive CD4 and CD8 T cells.

ACTIVE MOIETY

Comments:

The most frequently detected response was toward the HLA-DP4-restricted NY-ESO-1(157-170) epitope, which is also recognized by effector T cells. Notably, functional Treg specific for an HLA-DR-restricted epitope within the NY-ESO-1(115-132) peptide were also identified at high frequency in tumor tissue, suggesting that NY-ESO-1-specific Treg may suppress local anti-tumor immune responses. Together, our data provide compelling evidence for the ability of a cancer vaccine to expand tumor antigen-specific Treg in the setting of advanced cancer, a finding which should be given serious consideration in the design of future cancer vaccine clinical trials.
