【Abstract】Objective  To explore the feasibility that the recipient against donor antigen-specific T lymphocytes clones are formed,and the suicide genes are induced into the clone. In the end it may induce the transplanted-organ tolerance. Methods  The recipient rats were immunized by the donor rats-splenocytes, then the recipient’s T cell were isolated, purified and diluted with limited-dilute methods into single cell.The T cells were cultured by adding raise cells,ConA or IL2 under the different concentration and at last the T cell clone were formed. Results  A stable recipient against donor antigen-specific T cell clone was established. The difference among the different immune groups was very significant(t gt;t0.05). The T cell clone was not formed without raise cells or only with raise cells. The rare clone could be formed by ConA stimulation but without IL-2. The clone-forming rate was associated with concentration of IL-2. Conclusion The mature T cell is able to proliferate to form clone when the condition is suitable. The recipient is immunized with donor rats spleen cellular antigen. The T cells clones selected in the end are donor antigen-specific.
