| Research Abstract |
We examined T cell proliferation assay by co-culturing the T cells extracted from spleens of mice and mouse DFAT. In result, it was possible to suppress the proliferation of T cells in a concentration dependent of the DFAT. Then we examined for the immunosuppressive effect of DFAT in vivo. At first, establish a skin replacement transplant model and ectopic cardiac transplant model, we examined the survival prolongation of graft by DFAT administration. However, we didn't observed survival prolongation of graft by DFAT administration. Immunosuppressive effect in vitro is present, but it was found that not resulting to suppress rejection in vivo.
