[Comparative immunogenicity of irradiated and nonirradiated syngeneic and xenogeneic tumor cells containing a common specific transplantation antigen].
The authors compared the immunogenic activity for Syrian hamsters of native and irradiated syngeneic and xenogeneic tumour cells bearing on their surface common and SV40-specific transplantational antigen. The results obtained showed syngeneic tumour cells to be more immunogenic for the recipient than the xenogeneic tumour cells containing an antigen of the same specificity. Irradiation renders tumour cells, including the xenogeneic ones, more immunogenic, this possibly being associated with the capacity of nonirradiated cells to escape from immune recognition through their ability to divide.
