Abstract:
Objective:To investigate the effect and the mechanism of T cell vaccination in inducing heterologous antigen specific immune tolerance Methods:T cell vaccination were made from the spleen cells of SD rats, which were induced by ConA and were challenged with the spleen cells of guinea pig (the heterologous specific antigen) Normal SD rats were vaccinated intraperitoneally with TCV or 1640 culture buffer(blank control) respectively One way mixed lymphocyte reaction(MLR)?the apoptosis of peripheral T cells and the rate of CD4/CD8 in peripheral blood were assayed before and after vaccination.Results:MLR showed that the response captivity of SD rat spleen cells in TCV group were suppressed significantly after vaccination(P
