Abstract
The priming of tumor-antigen-specific T cells is critical for the initiation of successful anti-tumor immune responses, yet the fate of such cells during tumor progression is unknown. Naive CD4+T cells specific for an antigen expressed by tumor cells were transferred into tumor-bearing mice. Transient clonal expansion occurred early after transfer, accompanied by phenotypic changes associated with antigen recognition. Nevertheless, these cells had a diminished response to peptide antigenin vitroand were unable to be primedin vivo. The development of antigen-specific T cell anergy is an early event in the tumor-bearing host, and it suggests that tolerance to tumor antigens may impose a significant barrier to therapeutic vaccination.
