title: Tumor-specific T-cell memory: clearing the regulatory T-cell hurdle.
abstract: Antitumor immune responses can be stimulated by interfering with regulatory T-cell (T(reg)) function. However, this effect is short lived unless T-cell memory to tumor antigens can be generated. Our recent studies show that T(reg) cells not only limit primary responses to tumor/self-antigens in tumor-bearing hosts but also prevent the natural generation of T-cell memory to such antigens. Here, we discuss the role of T(reg) cells in suppressing T-cell memory after surgical excision of tumors and the potential clinical benefits of overcoming this suppression.
