(英) T cell immune responses are regulated by the interplay between effector and suppressor T cells. Immunization with Ag leads to the selective expansion and survival of effector CD4(+) T cells with high affinity TCR against the Ag and MHC. However, it is not known if CD4(+)CD25(+) regulatory T cells (T(reg)) recognize the same Ag as effector T cells or whether Ag-specific TCR repertoire modification occurs in T(reg). In this study, we demonstrate that after a primary Ag challenge, T(reg) proliferate and TCR repertoire modification is observed although both of these responses were lower than those in conventional T cells. The repertoire modification of Ag-specific T(reg) after primary Ag challenge augmented the total suppressive function of T(reg) against TCR repertoire modification but not against the proliferation of memory CD4(+) T cells. These results reveal that T cell repertoire modification against a non-self Ag occurs in T(reg), which would be crucial for limiting excess primary and memory CD4(+) T cell responses. In addition, these studies provide evidence that manipulation of Ag-specific T(reg) is an ideal strategy for the clinical use of T(reg). |
