ABSTRACT
Objective:
The present study was designed to investigate whether transfecting DC with tumor derived total RNA is an effective way to induce CTL and antitumor immunity.Methods:
DC were propagated from bone marrow(BM) of C57BL/6J(H 2k b?I A b)mice in vitro with GM CSF+IL 4.Tumor derived total RNA extracted from actively growing Hepa 1 6 cells was used to transfected DC.The phenotypes of DC were detected by FACS,the cytotoxicity of CTL was assayed by MTT method.Results:
The tumor derived total RNA transfected DC exhibited much more and longer plasm membrane processes and increased expression of MHC Ⅰ?MHC Ⅱ?CD80(B7 1)?CD86(B7 2).Conclusion:
This experiment has shown that DC transfected with tumor derived total RNA of C57BL/6J cells could stimulate effectively the responsiveness of syngenic splenic T cells to induce specific CTL against C57BL/6J cells.
