Abstract

The invention is a simplified model on kidney rejection in animals and its setting approach. The method involves isolating dendritic cells from male mice and isolating T cells from female mice and then using the naive T cells in vitro to culture concurrently with male dendritic cells. Those activated T cells from female origin were injected into renal cortex in male mice for the purpose of attacking renal cortex. The animal model simulates the renal transplant rejection method to enable effective induction of renal transplant immune reaction.

Claims (16)

1. A method for preparing an animal model simulating a transplant rejection, which includes:

(a) providing a dendritic cell, wherein the dendritic cell is obtained from a first animal subject;

(b) providing a lymphocyte, wherein the lymphocyte is selected from a second animal subject;

(c) co-culturing the dendritic cell and lymphocyte in vitro to form an activated T lymphocyte;

(d) creating an implant position in renal cortex of a third animal subject; and

(e) transplanting the activated T lymphocyte into the implant position in the renal cortex of the third animal subject;

wherein the first subject, the second subject, and the third subject are same species, and the activated T lymphocyte would attack the renal cortex after being transplanted into the implant position in the renal cortex of the third animal subject, thus a transplant rejection model in animals would be induced in the third animal subject.

2. The method of claim 1 , wherein the first animal subject, the second animal subject, and the third animal subject are mice.

3. The method of claim 1 , wherein the gender of the first animal subject and the second animal subject are different.

4. The method of claim 3 , wherein the first animal subject is a male mouse and the second animal subject is a female mouse.

5. The method of claim 1 , wherein the implant position is a tunnel or a pouch.

6. The method of claim 1 , wherein the lymphocyte is a CD4 + entity or a CD8 + entity.

7. The method of claim 1 , wherein the dendritic cell is obtained from a thigh bone marrow of the first animal subject.

8. The method of claim 1 , wherein the dendritic cell is obtained from a lymph node of the first animal subject.

9. The method of claim 5 , wherein a depth of the tunnel or a pouch is 0.5 cm.

10. The method of claim 2 , wherein an age of the mouse is 6-10 weeks old.
