英文摘要
(1) Using P25 TCR-Tg mice, we demonstrated that direct interaction between TCR and peptide-loaded antigen-presenting cells primarily determines the fate of naive CD4^+ T cells, even in the absence of T-bet expression and costimulatory signals. (2) Coimmunization of mice with P25 and OVA resulted in the enhancement of CD8^+ cytotoxic T cells specific for OVA and growth inhibition of EL-4 thymoma expressing OVA peptide leading to the tumour rejection, indicating that P25 exerts a potent adjuvant activity for antitumour immunity. (3) P25-stimulated P25 CD4^+ T cells augment antigen cross-presentation by APC. IFN-γ and IFN-γ-inducible genes play indispensable roles the Th1-mediated cross-presentation.
