Abstract

Viral oncogenes, mutated cellular oncogenes, or other adventitious agents that might contaminate vaccine preparations on inoculation of the host will encounter a T cell-mediated immune response which will play a determining role in the progression of neoplastic events or replication of contaminating viral agents. Using SV40 T antigen tumour systems as a model we discuss the regions of the oncoprotein that have an impact on tumourigenicity and the role of CD8 T lymphocyte immune responses in eliminating potential tumour cells. In addition, we discuss measures that counteract T cell immune responses to abrogate T cell-mediated immunosurveillance.
