Abstract

The aim of the present study was to develop an animal model to test the therapeutic potential of purified CD4 and CD8 T-lymphocytes against the intracerebrally implanted rat glioma cell line TZ363. Peripheral immunization of donor rats was performed by subcutaneous injection of viable TZ363 tumor cells while control animals received buffer injection. Donor splenic T-lymphocytes were prepared 14 days later and enriched by immune-bead MACS sorting. FACScan analysis revealed that of the pooled and sorted cells 91% of the tumor immune group were T-lympocytes and from the control animals 96%. The purified immune CD4/CD8 T-lymphocytes (1.2 to 5x10(7) cells) were injected intraperitoneally into 12 adult rats (three groups; each four animals), which were challenged five days later by an intracerebral injection of 5x10(4) TZ363 glioma cells. Four rats received 1.4x10(7) T-cells from control animals. While 3 of 4 animals developed a brain tumor and died in the control group, all animals, which received 5x10(7) immune T-cells survived the intracerebral tumor challenge. In the other groups survival rate depended on the amount of T-cells given. All other rats were sacrificed 32 days after intracerebral grafting. No tumor was found in these animals. Our data demonstrate that an anti-tumor T-cell response can be raised against the malignant rat glioma TZ363 and that purified CD4 and CD8 T-lymphocytes from tumor immunized donors can transfer protective immunity across the blood-brain barrier into recipient rats which are tumor challenged intracerebrally.
